II. Introduction to the Sundyne CompressorIntroduction to the Sundyne Compressor

Sundyne Pinnacle LF-2000 compressors have 1 to 4 compressor stages mounted to an integralgearbox, which increase the pressure of a continuous flow gas by applying centrifugal action.Sundyne Pinnacle LF-2000 compressors are most commonly used in chemical process plants toincrease the pressure in a recycle loop. They are also used in refineries, petrochemical plants, andpower generation plants. Within these facilities, Sundyne Compressors are used in booster,regeneration, vapor recover, boil-off, and other gas process applications.

Sundyne Pinnacle LF-2000 compressors offer industrial quality in a compact unit that features highreliability and ease of operation. It provides high-energy performance and competitive efficiencies.For detailed specifications for Sundyne Pinnacle LF-2000 compressors, see the specification sheetand bill of materials or consult Sundyne Compressors. For the primary components, see Section E,Unit Specific Data.

For information about additional custom equipment for the basic Sundyne LF-2000 products, seethe brochure that accompanies this manual.



III. Lifting Instructions

It is extremely important for the safety of personnel that proper lifting procedures befollowed for the Sundyne product. Lifting should only be done by trained personnel, using adequatelifting equipment, and by connection to proper lifting points on the Sundyne equipment. Thefollowing are instructions specific to utilizing the proper lifting provisions for the Sundyne equipment,and are meant to supplement your company’s training, experience, and procedures.

Lifting of Upper Housing

Two lifting eyes (851) are provided on top of the upper gearbox housing (101 upper), capable oflifting the upper housing alone, NOT for the entire gearbox assembly. The housing center of gravitylies between these lifting eyes, and therefore the housing will not tip forward or backward when thelifting eyes are used.

Lifting of Gearbox Assembly

Four lifting lugs (852) are provided on the lower gearbox housing (101 lower), two at each end,capable of lifting the entire gearbox assembly including upper and lower housings, shafts, gears, andbearings. The assembly center of gravity lies between these lifting eyes, and therefore the housingwill not tip forward or backward when the lifting lugs are used (as long as there are not anycompressor ends attached – see Lifting of Entire Compressor Assembly).

Lifting of Compressor End Assemblies

Each compressor case (1) has four lifting lugs welded at 90 degree positions around the outside ofthe case, each of which is capable of lifting the entire compressor end assembly including inlethousing, diffuser, shroud, seals, and seal housing. Use the lug that is positioned at the top of theassembly.

The cases and compressor end assemblies will hang at an angle when lifted by the lug. Thismeans that when removing from the gearbox mounting, the assembly may move abruptly from themounting orientation to a hanging angle, and can potentially cause harm during this process. Beextremely careful of the assembly movement during lifting.

Lifting of Entire Compressor and Gearbox Assembly

Four lifting lugs (852) are provided on the lower gearbox housing (101), two at each end, capableof lifting the entire compressor and gearbox assembly, including upper and lower housings, andcompressor ends.

With compressor ends mounted to thegearbox, the assembly center of gravity may lieoutside of these lifting eyes, especially withtwo compressor ends on one side and none onthe other side to provide counter balance.Therefore two of the lugs will becomeineffective as the assembly tilts forward. Toaccount for this, attach chains around the inletflanges of the compressor end assemblies,while also utilizing the two rear lifting lugs. Thefront two lifting lugs may be utilized if desired,but are not necessary.

IV. Inspection, Storage, and Installation

Inspection1. When you receive the Sundyne LF-2000 compressor, check for any

damage. If you find any, inform the carrier and Sundyne Corporationpromptly.

2. Use Outline drawing, Compressor and Gearbox drawings and bill ofmaterials to ensure that all auxiliary items are properly included.

3. Check the input shaft carefully. Seal drag may cause it not to turnfreely at first. This is normal. But if the shaft binds, it may bedamaged.

Short-term Storage − 1 day to 6 months1. If the compressor is to be stored near strong chemicals or salt water,

protect it immediately. To do this, follow steps 8 through 11 from thelong-term storage procedures. Failure to protect the compressor andthe auxiliary equipment could result in damaged parts.

2. Protect the unit from moisture and dust.

3. Make sure that the factory’s shipping covers for the housing flangesand the seal ports are securely in place.

4. Carefully follow the instructions provided by the manufacturer of themotor or turbine driver. If the motor was provided by Sundyne, thenthe motor manual is included in the Final Data package.

Long-term Storage − 6 months or more

If you store the LF-2000 for a long period, the methods you use are veryimportant. Please contact Sundyne at +1 303 425-0800, Arvada,Colorado, U.S.A. or +33 3 8038 3300, Longvic Cedex, France and askfor the Field Service Department for further instructions. Failure to storethe Sundyne equipment correctly can cause damage to the components.1. The best way to store the unit is to purge the gearbox and lube oil

system with Nitrogen to prevent condensation and dust frompenetrating into internal components. Otherwise, be sure the storagearea has:

♦ Relative humidity of 80% maximum; and

♦ Temperature range from 45° − 85°F (7° − 29°C).2. Make sure drain valves are open to allow any condensation to drain.



3. Coat internal parts of gearbox, wet end, and lube oil reservoir with oilsoluble rust preventative.

4. If the auxiliary lube system is available, circulate the oil and manuallyspin the bull gear once a month.

5. Do not allow contact of airborne chemicals with the internalcomponents of the unit.

6. If the unit is being stored near strong chemicals or salt water, protect itimmediately.

7. Protect the unit from moisture and dust.

8. Make sure that the factory’s shipping covers for housing flanges andseal ports are securely in place.

9. Store the unit indoors.

10. Use desiccant bags to absorb moisture.

11. After long-term storage, have an authorized Sundyne service engineerinspect all components to be sure that they work properly. Anycomponents not made by Sundyne (except mechanical seals) must beinspected or replaced by the manufacturer’s authorized personnel, atthe purchaser’s expense.

Because the storage location and unknown factors at the site ofstorage are beyond our control, Sundyne Corporation does notaccept any liability for damage to the equipment during storage, nordo we guarantee the quality of the equipment during and after thestorage period.

Installing the Suction and Discharge Piping

Guidelines:1. Clean the suction line.

2. Install a suction strainer to protect the impeller from damage by millscale, welding slag, or other foreign particles.

3. Make sure that the piping is aligned with the compressor flanges. Ageneral rule is to align the flanges with 1/16 inch (1.6 mm) maximummisalignment between parallel flange faces.

4. Support all piping independently of the compressor.

5. When you move the piping into place, never use excessive force at theflanged suction and discharge connections. This could strain the unit.



6. Use suction pipe that has a diameter at least as large as the diameter ofthe suction inlet of the compressor.

7. Make sure that the suction and discharge piping have no unnecessaryelbows, bends, and fittings. These increase the losses caused byfriction. Also, be sure that all piping and fittings are large enough tominimize losses caused by friction.

8. Before you connect the piping to the compressor, tighten the hold-down bolts on the compressor.

Leave a straight length of pipe, which is at least ten times the diameterof the pipe, between an elbow and the suction flange. If you useelbows at all, use only long-radius elbows.

9. Use block valves on both suction and discharge pipes to isolate thecompressor during shutdown, minimize process leakage, and reducethe likelihood of backflow through the compressor, which can causereverse rotation.

Seal Environment Control System

For the seal used with the compressor, always maintain the environmentshown on the specification sheet for your unit. For some arrangements andapplications, you may need a system to control the seal environment. Formany applications, you can obtain a standard system from the factory.

Make sure that the system is installed properly and that the ports are openor plugged. See Process and Instrumentation Diagram (P&ID) on theoutline drawing provided in the final data package.

You must drain all case drain ports and all gas tubing lines for liquid andreclose all drain ports previously identified before startup. Any liquid in theprocess loop can cause damage to the compressor components. Any liquidor contaminants in the seal system can damage the gas seals.

The gas seal system is shown in the outline drawing. The logic description islocated withing this manual in Section D, Compressor Operating Logic.



Baseplate Mounting

The baseplate must be leveled on the foundation using the leveling screwsmounted in the base’s beam bottom flanges. Use steel leveling padsbetween the leveling screws and concrete foundation. Level the baseplateso that the compressor and motor machined pads are within .002 in/ft (.17mm/m). After leveling fasten all of the anchor bolts.

Figure 1.1, Cross-section for Baseplate Mounting (Grout Optional)

Driver and Coupling

The motor and compressor coupling is installed at the factory if the motorwas provided by Sundyne (to locate the motor foot holes). Otherwise, themotor foot holes will have to be drilled in the field. In either case, the motorwill require realignment at the field site.

Alignment of the compressor and motor will take place after grouting andbefore connecting the suction and discharge piping. Ensure that thecompressor is fastened to its mounting plate. Using the motor jack screwsand motor foot shims align the motor to the compressor with the couplinginstalled and connecting the two machines. During alignment thrust thecompressor-input shaft toward the motor. It is recommended that laseralignment equipment be used to perform the alignment.



Alignment ParametersParallel misalignment allowed

.004 in (.101 mm)Equivalent Angulardisplacement allowed .004 in (.101 mm)Axial displacement allowed +/- .010 in (+/- .254 mm) from

Do not use tolerances given by the coupling manufacturer as thesetolerances indicate the maximum values the coupling can survive. Too largetolerances will cause added vibration, bearing damage, etc., and therefore itis recommended to align the motor as close to perfect as possible.

Temperatures have considerable influence on alignment and should beconsidered during alignment. Thermal growth of compressor can beestimated by the equation ∆H .α ( ).∆T H during cold alignments.

The following is the expected thermal growth of a Pinnacle LF-2000gearbox, which is independent of the process temperatures:

After cold alignment is complete and all systems are connected properly themotor and compressor should be operated until running temperatures arereached (approximately 2 hours). Shut down the unit and check to ensurethe alignment is still within tolerances. If tolerances are out then adjust thealignment to be true in the hot condition. Draw up a record for futurechecks.

V. Servicing

Lock-out/Tag-out GuidelinesFollow Your Companies Lock-Out / Tag-Out Procedure When Servicing Sundyne Compressors.

Never remove a lock or tag applied by someone else. Additional locks or tags should be applied ifmultiple groups are working on the equipment. Each responsible work group leader should apply alock or tag. Always treat conductors and equipment as if they are energized.

General Requirements

To increase the operating life of your compressor and keep it in good operatingcondition, you should inspect and service it regularly. Measure all of the operatingparameters as documented in the specific maintenance procedures and log yourmeasurements.

Make sure that all major equipment, such as lubricating pumps, heat exchangers,and instrumentation, perform according to the manufacturer’s recommendations.

Whenever you find a deviation from specifications, identify its source immediately,and take any corrective steps that are needed.

Gearbox Oil Specification

The oil used in Sundyne gearboxes must meet the specifications presentedin Field Engineering Bulletin 40.2.04. In general, an ISO viscosity grade 32 oil willmeet these specifications. Before using any oil, you should verify its properties byconsulting its manufacturer. Failure to use the proper gearbox lubricant will void thewarranty. The following page shows Revision C of Engineering Bulletin 40.2.04.Refer to Section D, Compressor Operation Logic, for lube system info specificto your unit.



FIELD ENGINEERING BULLETIN Effective August 1998 40.2.04 Rev. C

GEARBOX LUBRICANT RECOMMENDATIONSFor years the preferred gearbox lubricant for Sundyne compressors and compressors has been automotiveautomatic transmission fluid (ATF). However, over time the additives in automatic transmission fluid havechanged to coincide with the technical improvements in automobile transmissions. The additives in the newformulations of ATF, such as Dexron III, have been found to have negative effects on Sundyne gearboxesand could compromise mechanical integrity and reliability of the equipment.

ISO Viscosity Grade 32 general purpose or synthetic oils are the recommended lubricants for the Sundynegearboxes. Gearbox lube oil should be changed twice yearly or more frequently in severe environmentswhich may be detrimental to the lubricant. Oxidized oil is frequently characterized by a darkening and/orthickening of the oil. Operating of gearboxes with oxidized lubricant should be avoided.

Synthetic oils possess different characteristics than conventional oils which make them desirable forvarious extreme conditions such as high and low temperature operation. Synthetic oils offer very low pourpoints, high temperature oxidation stability and a higher viscosity index.

The operation of Sundyne equipment in high or low ambient conditions may require special consideration ofgearbox lubricant and/or supplemental protective equipment such as heat exchangers or gearbox heaters.

The lubricant chosen must be compatible with gearbox elastomers, Viton and Buna N. Any oil that containsan inert additive such as PTFE, molybdenum disulfide or silicon should not be used in Sundyne gearboxes.Use of lubricants containing inert additives will void the product warranty.

Regular Maintenance1. Gearbox oil: Check the level of the oil in the gearbox immediately

before and after initial startup, and regularly while the compressor isrunning. Be sure to keep the level of the oil within the design limit. Youcan add oil while the compressor is running.

2. Oil pressure: In normal operation, the oil pressure supplied to thegearbox should be between 2.1 − 4.1 barg (40 − 60 psig).

3. Changing the gearbox oil and filter: Change the oil in the reservoirand the oil filter elements every 6 months.

4. Seal leakage: Check the gas seal flow rates. If the flow rate exceeds150% of the value that is established as normal then investigate. Theseal may need to be replaced.

5. Driver: Inspect the driver to make sure that it performs according tothe manufacturer’s specifications, found in the Final Data package if themotor was provided by Sundyne.

6. Coupling: Inspect the coupling according to the manufacturer’sspecifications, found in the Final Data package if provided by Sundyne.

Never operate the compressor without first checking the coupling guard. Acompressor with a missing or incorrectly installed guard can allow rotating shafts tocontact clothing, body parts, tools or other loose items, and result in severepersonal injury or loss of life.

VI. Start-up/Operation/Shutdown

If a Sundyne supplied control panel is to be used with the Sundyne Pinnacle LF-2000 compressor,use the control panel recommended start-up procedure in addition to these instructions.

Some form of control is required for the majority of Sundyne compressor applications. The purposeof control is twofold: 1) to achieve the desired performance as required by process conditions and2) to protect the compressor from mechanical damage due to surge or overload conditions.

This section is a general guideline on controls. Refer to Section D, Compressor OperatingLogic, for detailed information on operation of your unit.



Surge ControlIt is recommended that a surge control system be installed whenever there is any chancethat the process flow could decrease appreciably from design flow. In most surge controlsystems, a flow sensor is placed in the suction line to the compressor. The signal from thissensor is input to a controller which controls a valve in the bypass loop. When the minimumsafe flow is reached, this valve opens and the flow through the compressor is kept abovethe surge point. Again, the recycled gas must be cooled to prevent heat build-up. Bothpneumatic and electrical surge control systems are available.

Suction ThrottlingSuction throttling is generally the most economical control method with a constant speeddrive. Throttling the control valve on the suction side causes a reduction of inlet pressure tothe compressor. Although the compressor creates the same compression ratio as if it wereunthrottled, the discharge pressure is reduced. The reduction of inlet pressurecorrespondingly decreases inlet gas density, and thus, power consumption. Suction throttlingalso has the advantage of slightly lowering the compressor surge point.

Discharge ThrottlingDischarge throttling is control by means of a valve placed at the compressor discharge. Aconstant speed compressor will always operate on its design head-flow curve. For a givensystem operating point, the compressor will operate at the system flow rate, thus producingmore head than the system requires. This excess head is throttled by the discharge valve.Since the throttling occurs downstream of the compressor, there are no power savings bythis method. Discharge throttling offers no real advantages over suction throttling, but isnonetheless an acceptable control method.

Speed ControlSpeed control is the most efficient means of compressor control. To operate at pointsbelow the design head-flow curve, the driver speed may be reduced accordingly. Thiscreates an infinite “family” of head-flow curves on which the compressor may operate.Since consumed horsepower, assuming constant inlet conditions, varies as the cube of thespeed, substantial power savings can be realized. Also, the compressor surge point islowered proportional to the speed decrease. This method is used mainly on turbine drivenunits although variable speed motors or mechanical drives are available. Since the main lubeoil pump in the Sundyne compressor is driven by the gearbox input shaft, provision must bemade so the speed is not reduced to a point where adequate lube oil pressure is no longerpresent.

Flow Bypass

Flow bypass requires a recycle line from the compressor discharge to suction. Thecompressor is operated at the desired flow or discharge pressure and the excess flow notrequired by the process is recycled through the bypass. A cooler is required in the loop to



cool the recycled gas to normal suction temperature. This method is generally less efficientthan other methods discussed, but may be warranted in some special situations.

Compressor Control During Start-Up

A. Suction throttling (preferred method). Start compressor with the discharge valveopen while throttling the suction valve to bring the compressor to the designoperating point.

B. Discharge throttling. Start the compressor with the suction valve completely openwhile throttling the discharge valve to bring the compressor to the design operatingpoint.

C. Other Methods – Insure that the compressor does not go into surge (flow too low)or that the design horsepower is not exceeded (flow too high) while starting oroperating the compressor. Check the unit specification sheet for flow limits

Run-In of the Compressor

If the compressor is to be run-in or mechanically tested under conditions which areconsiderably different from those that the unit is designed for (such as gas molecular weight,suction pressure, flow rate, etc.) Sundyne should be consulted to insure that the run-inconditions are compatible with the compressor.



VII. TroubleshootingGearbox and Compressor

Many factors affect the performance of your compressor. Among them are suction pressure,temperature, molecular weight, driver speed, flow rate, and discharge control. You need to checkall of these when there is a problem with the compressor and when you are analyzing theperformance of the system. For details on the performance of the compressor including theperformance curve, refer to the final data package, sections 1 and 2, and specification sheets.Table 10.1 provides information for analyzing gearbox and compressor problems.

Table 10.1 Troubleshooting for Gearbox and CompressorTrouble Possible Cause Investigative and Corrective Action

A component of the drive, such asthe coupling, has failed, or an item ismissing from the assembly

Disassemble and inspect the failedcomponent, if it is present. If not, add therequired component to the assembly.

The drive shaft rotates in the wrongdirection

Make sure that the drive shaft is rotating inthe direction shown by the arrow on thecompressor gearbox.

The compressor produces noflow and no pressure at start-up

The suction valve or the dischargevalve is closed.

Check the valving (see Section D,Compressor Operating Logic).

The flow is too high. Check the head rise and the flow rateagainst the performance curve.

The driver shaft is rotating in thewrong direction.

Make sure that the drive shaft is rotating inthe direction shown by the arrow on thecompressor gearbox.

The suction pressure is low. Check the Sundyne specification sheets.

Recirculation from the discharge tothe inlet is excessive.

Check the flow through the external piping,such as the bypass

The molecular weight is not that forwhich the compressor wasdesigned.

Check the molecular weight against thevalue given on the specification sheet. Lowmolecular weight will cause low dischargepressure.

The driver speed is too low. Check the speed against the value listed onthe Sundyne specification sheets.

The head rise is insufficient.

The pressure gauges or the flowmeters are in error

Calibrate the instrumentation.

The pressure gauge is faulty. Check the accuracy of the gauge.The oil pressure in the gearboxis low.

The main lubricating pump has failed. Remove the pump and check for damage.

Compressor Mechanical Seals

Table 10.2 provides information on problems with single, double, and tandem seal units.

Table 10.2 Troubleshooting for Compressor Mechanical SealsTrouble Possible Cause Investigative/Corrective Action

The system is operating at a low flowrate or a low inlet pressure, causingvibration of the high-speed shaft,bouncing on the face of the seal, andchipping on the nose of the carbonseal.

Make sure that the compressoralways operates above the specifiedminimum flow rate and/or inletpressure.

The action of the stationary facespring on the seal is rough and sticky

If contamination in the process gas(from entrained solids) causes asticky seal, there may be need for aseal flush, double seals, or tandemseals.

The seal is worn or damaged. Replace cartridge seal.

Leakage around the sealsuddenly increases

The seal on a low-temperaturecompressor is icing, or there is heavycondensation on the atmosphericside of the seal.

Purge the atmospheric side of the sealwith dry nitrogen gas.

Detailed Description of Compressor End Assembly:

Detailed descriptions of the assembly steps are listed below. These steps are to be followed foreach stage of the compressor. Item numbers are provided in parenthesis. . Refer to theCompressor Gearbox Drawing, found in Section E, for a cross-section view with item numbersidentified, and the unit BOM for part numbers corresponding to each item number. This sectionassumes the gearbox is complete and shaft end-play dimensions are within tolerance:

1) Install Seal Housing (30) into Compressor Case (1).

1a) Lift compressor case (1) usingwelded on lifting lug, and set on its sidewith the discharge flange oriented as it willbe when mounted to the gearbox.

1b) Apply silicone based lubricant to o-ring(900), and install on the seal housing (30)that will insert into the compressor case(1). Slide the o-ring (900) down the postOD until it seats in the corner.

1c) Lift the seal housing (30) with its flangesoriented approximately relative to the case(1) as required.

TIP: Use a hoist with lifting strap around theupper pipe of the seal housing, in line withthe center line of the seal housing.

1d) Install seal housing (30) into compressorcase (1).



1e) Lubricate the eight ¾”-10 mountingscrews (501) with Anti-Seize ThreadLubricant and install to mount the sealhousing to the case. Torque to the valuespecified in Table I.

1f) Install the drain pipe (800) into the sealhousing (30). The port is oriented with theslot in the mounting face of the compressorcase (1). The port and pipe are an NPTconnection, and the pipe may be tightenedusing a pipe wrench on its exposed lengthbeyond the case mounting surface.

1g) Apply silicone based lubricant to o-ring(901), and install into groove on the noseof seal housing (30) that will insert into thegearbox housing (101).

2) Mount Compressor Case (1) onto Lower Gearbox Housing (101).

2a) Apply Locktite 242 Thread-locker (blue)to the six case studs (500), and install intomounting face of compressor case (1).Thread in until they bottom out in tappedhole.

Apply Anti-Seize Thread Lubricant to theexposed end of thread where the nut(700) will go.



2b) The compressor case (1) and compressorend assembly should only be lifted by thelifting lug attached to the compressor case(1).

2c) Using a hoist and adequate connection tothe lifting lug of the compressor case (1),lift the case into position near the gearbox(101) mounting face.

Use caution to avoid hitting the end ofthe high speed shaft with any part of thecompressor end assembly.

2d) Align studs (500) with holes in gearbox(101) mounting face, and insert until studsare extending through the holes by severalthreads only.

NOTE: There is not enough clearance behindthe mounting face to put nuts onto thestuds when they are extending all the waythrough the mounting holes.



2e) Slide 6 nuts (700) behind the gearbox(101) mounting face, and thread them ontothe studs (500) as far as possible.

2f) Several iterations of moving thecompressor case closer to the gearbox,and threading the nuts onto the studs, maybe required before compressor casemounts flush to the gearbox.

When tightening nuts to pull the case ontothe gearbox, be sure to alternate tighteningof the nuts to keep the case square to thegearbox. Excessive force should not beused to tighten the nuts.

If excessive force is required to tightenthe nuts before the case contacts thegearbox mounting face, then STOP. Thecase may not be square to the gearbox,and damage may be caused to the case,seal housing, and/or gearbox. Loosen thenuts and start over.

2g) Tighten the 6 nuts (700) (1”-8)tocomplete mounting of compressor case (1)to gearbox (101). Use an alternatingsequence to tighten the nuts, starting atsnug tight, and advancing to full strengthtightening. Because of the limitedclearance for turning the wrench at someof the nut locations, a special wrench (1-1/2” open end 4-way angle head) isprovided in the Tool Kit to facilitatetightening.



3) Install Seal Cartridge (60).

3a) The seal cartridge (60) has a 2 pieceinstallation plate mounted to thecompressor side of the seal (away fromthe gearbox).

The seal installation plate must not beremoved until after the seal is mountedonto the shaft and into the seal housing(30).

Remove the plastic shipping cover fromthe opposite end of the seal cartridge (30).

3b) The seal drive pins (562) on theoutput shaft (140) must be orientedproperly relative to the seal when the sealis installed. Otherwise the seal may shearor otherwise damage the pins uponinstallation.

Use a straight edge tool, such as a smallruler, to align one of seal drive pins (562)on the output shaft (140) with the sealhousing (30) mounting hole that is justslightly to the right of 12 o’clock. Rotatethe shaft (140) if required, using the shaftrotation tool supplied in the Tool Kit.



3c) Remove plastic shipping cover from theseal cartridge (60), and Krytox o-ringlubricant to the 5 o-rings (906, 907, and908) on the OD of the seal cartridge (60).

Krytox o-ring lubricant isrecommended by seal manufacturer,instead of silicone based lubricant. Avoidexcessive amounts of lubricant, as it couldcontaminate the seal faces.

The seal cartridge installation plate,mounted to the front of the seal cartridge(60), has a deep scribe across both piecesaligned with one mounting hole. Wheninstalling the seal cartridge (60), align thescribe with same hole in the seal housing(30) that the drive pins (562) were alignedwith.

3d) Slide seal cartridge (60) into seal housing(30) until it is several inches away fromcomplete installation. Use two hands, withpalms on the installation plate and fingersbehind the seal cartridge flange. Gettingthe seal started into the seal housing maypresent some difficulty because of themultiple o-rings and matching steps in boreand on the seal OD. Moderate pressureand slight rocking back-and-forth of theseal will facilitate the installation.



3e) To prevent rotation of the sealduring the final part of the installation(when the drive pins (562) will engage),two pieces of 3/8-16 UNC “All-Thread”studs, approximately 6” long, should beinstalled into two mounting holes 180°apart. Two nuts jammed together at theends will facilitate removal of the studs.

3f) Push the seal cartridge (60) in as far aspossible.



3g) Remove the two “All-Thread” studs.

3h) Lubricate the twelve screws (502) (3/8”-16) with Anti-Seize Thread Lubricant andinstall 2 screws in place of the studs (at180° apart). Use these to pull the sealcartridge (60) into place, by alternatelyturning each about a ½ turn until the seal iscompletely seated.

If excessive force is required to tightenthe screws before the seal is seated, thenSTOP. The seal may not be square to theseal housing, and damage may be causedto the seal or shaft. Remove the screws,utilize the jack screw holes in the seal toback the seal off, and start the installationover.

Install the rest of the twelve seal mountingscrews (502) (3/8”-16) and tighten to thetorque specified in Table I.

3h) Remove the outer portion of the sealinstallation plate (part of the seal cartridge(60) assembly) by removing the 6attachment screws (#10-24 x .62”LG).

Lift carefully away from seal.



3j) Remove the inner portion of the sealinstallation plate (part of the seal cartridge(60) assembly) by removing the 6attachment screws (#10-24 x .75”LG).

Lift carefully away from seal.

3k) Set aside the 2 piece installation/removalplate and 12 screws to use if the seal isever removed.

NOTE: These pieces are supplied as partnumber TK01GC02 for new compressorassemblies with seals installed at thefactory.

4) Install Backing Ring (61) if required

Refer to your BOM to determine whichstages, if any, require a backing ring.

4a) Place backing ring (61) onto seal cartridge(60).



4b) Install the 6 mounting screws (508) (#10-24 x .5”LG) to mount the backing ring tothe seal. Torque to the value specified inTable I.

5) Install Impeller (2).

5a) Check the impeller (2) by first inspectingthe blades and shroud for any rubs ormaterial build-up.

If any physical discrepancies are found,have the impeller re-balanced at a qualifiedSundyne facility.

Inspect nose face, where impeller nutcontacts, for evidence of galling. Stonesurface if required.

5b) Check the hirth coupling on the impeller(2) for any raised material on the teeth ordebris in alignment hole. Ensure the teethare clean and free of any deformation.



5c) Apply Anti-Seize Thread Lubricant tothreads on both ends of impeller stud (3).Install impeller stud (3) into end of outputshaft (140) by inserting the end of the studthat has approximately ¼” thread relief atthe tip.

Insert impeller stud (3) until it bottomsout in output shaft (140).

NOTE: The impeller studs (3) and impellernuts (5) will have LH (left-hand) threadsfor compressor Posts A and C, and RH(right-hand) threads for compressor PostsB and D.

5d) Approximately align the alignment hole inthe hirth of the impeller with the pin in thehirth of the shaft (140). Install impeller (2)over stud (3) until hirth teeth on impeller(2) and shaft (140) lightly contact. Rotategently back and forth until the hirth teethand alignment pin and hole engage.

5e) Apply a thin layer of MoS2 Dry FilmLubricant to the flat mating faces of theimpeller nut (5), and the impeller (2), toprevent galling between the two parts.

Sundyne has determined that the MoS2

Dry Film Lubricant prevents galling at thisinterface much better than Anti-SeizeThread Lubricant.



5f) Lubricate the impeller nut o-ring (902) witha silicone based lubricant, and bottom it onthe pilot of the impeller nut (5).

If PTFE static seals are utilized in the unit,this position will utilize a spring energizedPTFE seal. When installing the seal on thenut pilot the open end of the seal will facethe mating face of the impeller nut.

5g) In order to torque the impellers (2),rotation of the shafts must be prevented.This is done by inserting a rod through theholes in the upper gearbox housing andone of four holes in the bull gear. Do notrotate the shaft any more than necessary toalign the closest hole in the gear with therod hole, so that rubbing of the seal facesis minimized.

Remove the pipe plugs (850) from bothsides of the upper gearbox housing (101).

5h) Insert a rod entirely through the uppergearbox housing (101) and the bull gearon the low speed shaft (120). If at first ahole on the bull gear is not aligned with theholes, rotate the input shaft using a strapwrench.

Paint the holding rod red and make extralong for increased visibility as a reminderto remove before operation of unit.



5j) Install the impeller nut (5) (with o-ring andlubricated face) onto the exposed threadof the impeller stud (3) until the nutcontacts the impeller. Torque to 160 ft-lbs.

NOTE: Impeller studs (3) and impeller nuts(5) will have LH (left-hand) threads forcompressor Posts A and C, and RH(right-hand) threads for compressor PostsB and D.

5g) The holding rod for the bull gear must be

removed after applying torque to theimpellers. Serious damage to the unit willoccur if a start-up is attempted withoutremoving the rod. Replace the pipe plugs(850) into both sides of the upper gearboxhousing.

6) Install Shroud (7) into Diffuser (13).

6a) Orient diffuser (13) with flange side up.

6b) Insert 2 pieces of .062” thick shim stock(158) into diffuser (13), aligning thediffuser pins (503) with the correspondingholes in the shim stock.

Installing shim stock during the initialclearance check ensures that there will beinitial impeller clearance, and the impellerwill not be damaged



6c) Install lifting eyes (provided in the ToolKit) into each of the 3 threaded holes (½”-13UNC) in end of shroud (7) (oppositethe impeller profile surface).

6d) Lower shroud (7) into diffuser (13),aligning the diffuser pins (503) with thecorresponding holes in the shroud (7).

6e) Remove the 3 lifting eyes from the shroud(7).

6f) Install the screws (504) to attach theshroud (7) to diffuser (13). Quantity andsize will vary by unit. Torque to the valuespecified in Table I.



7) Lift Assembly of Shroud (7) and Diffuser (13).

7a) Attach the Diffuser Lifting Tool, providedin the Tool Kit, to diffuser (13) by insertingone end of “C” into diffuser opening andsecuring with a ½”-13UNC x 3.00” LGscrew through the slot on the tool into oneof the threaded jack screw holes on thediffuser flange. Attach an eyebolt throughone of the holes in the other end of thetool, such that the diffuser hangsapproximately horizontally when lifted.

7b) Slowly lift the diffuser by the eyebolt onthe Diffuser Lifting Tool, using a suitablestrap or other connection



8) Check Clearance Between Shroud (7) and Impeller (2).

8a) Using about a 3 foot length of lead solderwire (.06”-.12” dia), create a circular ringat the base of the shroud profile, attachingwith standard masking tape along itslength. Cut off excess wire where thecircle joins back together.

8b) Carefully slide the assembly of shroud (7)and diffuser (13) into the compressor case(1) (which is already mounted on thegearbox). The mounting provisionsbetween the diffuser (13) and compressorcase (1) are not used for this assembly.

8c) Lubricate o-ring (904) with siliconelubricant, and install on the smallestdiameter groove of the shroud (7).

If PTFE static seals are utilized in the unit,this position will utilize a spring energizedPTFE seal. When installing the seal on theshroud the open end of the seal will facethe mating face the step on the shroud.



8d) Lift the inlet housing (6) using a hoist andan eyebolt installed into the 5/8”-18 UNCthreaded hole on OD of flange.

8e) Assemble inlet housing (6) to compressorcase (1) over compressor case studs(505).

8f) Install four of the compressor case nuts(705) and tighten to the torque specified inTable I.

8g) Remove the four compressor case nuts(705) and inlet housing (6) fromcompressor case (1).



8h) Remove the assembly of the diffuser (13)and shroud (7), using the Diffuser LiftingTool.

8i) Remove the lead solder wire, which shouldhave “pinched” impressions from each ofthe impeller blades (if not, the initial shimstack was too large).

8j) Measure several of the “pinched”impressions in the wire and calculate themean value for the clearance between theimpeller (2) blades and the shroud (7).

If the measurements vary more than +/-.003”, redo the impression after verifyingthe following:- ensure that the lead circle was attachedat a constant shroud diameter.– ensure that the shroud was seatedsquarely in the diffuser. Verify using adepth micrometer from the diffuser flangeto the shroud flat surface.

Shimming/Clearance Setting Note:. The relation between the installed shim thickness andthe desired running clearance will depend upon the thrust position and the end-play of the highspeed shaft. The lead impression height represents the impeller being thrust towards thegearbox, and does not factor in the end-play. The clearance setting will vary from unit to unitand from stage to stage within the same unit. For setting the clearance of a particular stage on aparticular unit, the Build Sheet (form number ISO2840, found in Section E) and the calculationsbelow must be referred to.

Calculations :

Factory Impeller Clearance (A) from Build Sheet = _______________

Subtract measured clearance from lead impression − _______________

Add Shaft End Play (H) from Build Sheet + _______________

SUBTOTAL = required additional shim = _______________

Add measured shim thickness (already installed) + _______________

TOTAL = required total shim thickness = _______________ ± .003”



8k) Based upon the lead impressionmeasurements, and the Build Sheetinstructions (see note above), install therequired thickness of shim pack (158).

8m) Confirm the clearance by repeating steps8a through 8k. Repeat as necessary untilcorrect clearance is obtained

9) Install Assembly of Shroud (7) and Diffuser (13) into Compressor Case (1).

9a) Follow the instructions from steps 7a, 7b,8a, and 8b.



10) Install inlet housing (6) into compressor case (1).

10a) Lift the inlet housing (6) using a hoist andan eyebolt installed into the 5/8”-18 UNCthreaded hole on OD of flange.

10b) Assemble inlet housing (6) tocompressor case (1) over compressorcase studs (505).

10c) Install the compressor case nuts (705)onto the case studs (505). Quantity andsize will vary by unit. Torque to the valuespecified in Table I. Use a crossingpattern to alternately tighten nuts, first tosnug tight, then to specified torque (seeexample below for an 8 nut configuration).

Detailed Description of Compressor End Disassembly:

Detailed descriptions of the disassembly steps are listed below. These steps are to be followedfor each stage of the compressor. Item numbers are provided in parenthesis. . Refer to theCompressor Gearbox Drawing, found in Section E, for a cross-section view with item numbersidentified, and the unit BOM for part numbers corresponding to each item number. Suction,discharge, and seal support piping do not need to be disconnected, unless the compressor casewill be disassembled from the gearbox. The unit should be allowed to cool down beforeperforming any disassembly.

1) Remove Inlet Housing (6) from the Compressor Case (1).

1a) Remove the compressor case nuts (705)from the case studs (505). Quantity andsize will vary by unit.

1b) Support the inlet housing (6) usinga hoist and an eyebolt installed into the5/8”-18 UNC threaded hole on OD offlange.

1c) Slide the inlet housing (6) away from thecompressor case (1) over the compressorcase studs (505).

The lifting point is not at the center-of-gravity of the inlet housing, so the housingwill tend to swing out when leaving theassembly. Be extremely careful as it isremoved.



2) Remove assembly of shroud (7) and diffuser (13) from compressor case (1).

2a) Start to slide the diffuser (13) outof the compressor case (1), by using the 3jack screw holes in the diffuser flange and ½”-13UNC x 3.00” LG screws.

2b) Attach the Diffuser Lifting Tool, providedin the Tool Kit, to the diffuser (13) by insertingone end of the “C” into the diffuser opening,and securing with a ½”-13UNC x 3.00” LGscrew through the slot on the tool into one ofthe threaded jack screw holes on the diffuserflange. Attach an eyebolt through the hole inthe other end of the tool, and support with ahoist. Carefully slide the diffuser (13) out ofcompressor case (1).

The lifting point may not be at thecenter-of-gravity of the diffuser, so it may tendto swing out when leaving the assembly. Beextremely careful as it is removed.

3) Remove shroud (7) from diffuser (13) (if required).

NOTE: The shroud should only be removed ifit needs service or replacement, or ifshimming for impeller clearance needs tobe redone.

3a) Set the diffuser (13) on a flat surface, withthe flange side up.

3b) Remove the screws (504) that attach theshroud (7) to diffuser (13). Quantity andsize will vary by unit.



3c) Install lifting eyes (provided in the ToolKit) into each of the 3 threaded holes (½”-13UNC) in exposed end of shroud (7).

3d) Raise shroud (7) out of diffuser (13), usinga hoist and the three lifting eyes.

3e) Set the shroud (7) on a flat surface, beingcareful to avoid damaging the impellerprofile surface.

3f) Inspect impeller profile surface of theshroud (7) for any rubs, material build up,or damage. Buff out small discrepancies,but contact Sundyne if any significantdamage is present.

4) Remove Impeller (2).

4a) In order to remove the impeller (2),rotation of the shafts must be prevented.This is done by inserting a rod through theholes in the upper gearbox housing andone of four holes in the bull gear. Do notrotate the shaft any more than necessary toalign the closest hole in the gear with therod hole, so that rubbing of the seal facesis minimized.

Remove the pipe plugs (850) from bothsides of the upper gearbox housing (101).

4b) Insert a rod entirely through the uppergearbox housing (101) and the bull gearon the low speed shaft (120). If at first ahole on the bull gear is not aligned with theholes, rotate the input shaft using a strapwrench.

Paint the holding rod red and make extralong for increased visibility as a reminderto remove before operation of unit.



4c) Remove the impeller nut (5) from theimpeller stud (3) by unscrewing in theproper direction (see note below).

NOTE: Impeller studs (3) and impeller nuts(5) will have LH (left-hand) threads forcompressor Posts A and C, and RH(right-hand) threads for compressor PostsB and D.

4d) Remove impeller (2) by sliding off overstud (3)..

4e) Remove impeller stud (3) from end ofoutput shaft (140) by unscrewing in theproper direction (see note below). Twonuts may be jammed together on exposedthreads to facilitate removal. Left-handthread nuts are provided in the Tool Kit.Threads are 5/8”-18 UNF.

NOTE: The impeller studs (3) and impellernuts (5) will have LH (left-hand) threadsfor compressor Posts A and C, and RH(right-hand) threads for compressor PostsB and D.



4f) Check the impeller (2) by first inspectingthe blades and shroud for any rubs ormaterial build-up.

If any physical discrepancies are found,have the impeller re-machined and/or re-balanced at a qualified Sundyne facility.

4g) Check the hirth coupling on the impeller(2) for any raised material on the teeth ordebris in alignment hole. Ensure the teethare clean and free of any deformation.

5) Remove Backing Ring (61) (if required).

Refer to your BOM to determine whichstages, if any, require a backing ring.

5a) Remove the 6 mounting screws (508)from the backing ring (61).



5b) Remove backing ring (61) from sealcartridge (60).

6) Remove Seal Cartridge (60).

6a) Locate the 2 piece installation/removalplate and 12 screws.

NOTE: For seals that were installed in theunit at the factory, these pieces aresupplied as part number TK01GC02. Ifthe seals were installed by the end-user,these pieces should have been stored forlater seal removal.

6b) The inner rotating member of theseal cartridge has a radial scribe line on itsface, as does the inner portion of theinstallation plate. These two lines must bealigned, otherwise damage to the shaftdrive pins (562) will occur during re-installation of the seal cartidge (60).

Install the inner portion of the sealinstallation plate to the seal cartridge (60),using the 6 attachment screws (#10-24 x.75”LG).



6c) Install outer portion of the seal installationplate to the seal cartridge (60) using the 6attachment screws (#10-24 x .62”LG).Be sure to align the scribe line on the outerportion with that on the inner portion.

6d) After installing the installation plate,remove the 12 screws (502) that mountthe seal cartridge (60) to the seal housing(30).

6e) Use two of the seal mounting screws(502) as jacking screws in the twothreaded holes in the seal cartridge (60)flange. Unseat far enough to grab theflange, and pull to remove the sealcartridge (60) from the seal housing (30).

The seal weighs approximately 20 lbs,and therefore must be carefully supportedwhen removing, to avoid dropping anddamaging the delicate internals of the seal.



7) Remove the Compressor Case (1) from the Gearbox Housing (101).

7a) Support the compressor case (1) using ahoist attached to the welded on lifting lug.

7b) Loosen the 6 nuts (700) on thecompressor case studs (500), behind thegearbox (101) mounting flange, and backthem off as far as possible. They will notcome off yet since the end of the studs areinserted into counter-bore holes in the wallof the gearbox (101).

Keep fingers away from the ends of thestuds and nuts (only contact the nutwrench flats), to avoid injury if thecompressor case should unexpectedly shiftas the nuts are backed off.

7c) Several iterations of moving thecompressor case (1) away from thegearbox (101), and backing the nuts (700)off of the studs (500), may be requiredbefore the the nuts (700) are able to beremoved from the studs (500).

Keep the compressor case square withthe gearbox mounting to avoid damagingthe shaft and seal.



7d) Using a hoist and adequateconnection to the lifting lug of thecompressor case (1), lift the case awayfrom the gearbox (101), and set downcarefully with the seal housing (60)exposed for removal.

Do not attempt to lift thecompressor case by the seal housingpiping, as the piping will break and severeinjury may result.

Use caution to avoid hitting the end ofthe high speed shaft with any part of thecompressor end assembly.

8) Remove the Seal Housing (60) from the Compressor Case (1).

8a) Attach a lifting strap around the upperpipe of the seal housing, in line with thecenter line of the seal housing, and supportwith a hoist during disassembly.

Detailed Description of the Gearbox Assembly:

Detailed descriptions of the assembly steps are listed below. Item numbers are provided inparenthesis. . Refer to the Compressor Gearbox drawing CG01GC03 for a cross-section viewwith item numbers identified, and the unit BOM for part numbers corresponding to each itemnumber:

1) Clean Gearbox Housing (101).

1a) Thoroughly clean each half of the gearboxhousing (101), inside and out, of old oiland foreign materials. All sealant materialon the split line surfaces must be removedusing a scraper, then the surfaces must becleaned thoroughly, and stoned. Removeany sealant that may have extruded aroundthe edges or into any slots or holes.Carefully inspect the mating surfaces of thegearbox halves, all the bores, and o-ringgrooves. Clean and deburr as needed.

If the gearbox is mounted to the base-plate and integral oil sump, care must betaken to avoid dropping any material intothe oil sump, especially old sealant anddebris.

Split Bearing Functional Note: All the bearings (151A through F) on this unit have a splitbody design, enabling them to be removed one half at a time while the shafts and compressorends remain intact. A radial pin extending from the bearing OD sits within a slot on the lowergearbox housing (101) split line to orient the bearing during operation. In order to remove abearing half, the upper gearbox housing (101) must be removed, and the bearing rotated to aposition where its own split line is horizontal. In this position the two socket head cap screwsthat hold the halves together may be removed, and then the bearing half itself may be removed.Each bearing will require a different degree of rotation to achieve this position.



2) Install Output Bearings (151A & B, or C & D)

It is a good idea to mark each bearing half and end plate with a lettercorresponding to it’s Post position (A, B, C, or D). When they are separated later forendplay shimming, they will need to be kept together for proper re-assembly. It is alsoimportant that they are installed at the proper location, since they have a particular rotationdirection (see rotation arrow on bearing) and load carrying orientation. Anti-rotation pinson the bearing fit OD ensure that the bearing is oriented correctly when installed at theproper location, by fitting into a groove on split line of the lower gearbox housing.

2a) Having the vibration probe bearingbrackets already installed on the bearingsfacilitates handling of the bearings.Carefully lower the bearing into the bore,with the bracket at the top of the bearingfacing the inside of the gearbox. Slide thebearing toward the outside of the gearboxuntil the bearing flange seats properly.Repeat for all the output bearings (151A& B for a single pinion machine, and C &D for a double pinion machine).

Be extremely careful with the temperature element and vibration probe leads extendingfrom the bearings, especially when rotating. When the bearing is rotated with probesmounted in brackets, the lube supply pipe to the bearing will be very close to the probes

2b) Rotate the bearing in the bore until thebearing split line is horizontal, and therecessed socket head cap screws holdingthe halves together are accessible. Thismay require the bracket to be rotated tothe bottom.

2c) Remove the 2 recessed socket head capscrews (#8-32UNC) holding the halves ofthe bearing together.



2d) The bearing halves are pinned together,and require some effort to separate. Usethe pry grooves, located within the lubeannulus feature, to begin the separation.

A simple pry bar may be constructedto make the separation easier. Use an allenwrench, ground down to a flat “screw-driver”tip at the end.

2e) Complete the bearing separation byholding the lower half down in the gearboxbore while pulling the upper half off.

2f) For units with two output shafts (130 and140), repeat all of the steps of this sectionfor the second set of bearings.

3) Install Input Bearings (151E & F).

3a) The vibration probe bearing bracketsshould already be installed on the bearings.Carefully lower the bearing into the bore,with the bracket at the top of the bearingfacing the inside of the gearbox. Slide thebearing toward the outside of the gearboxuntil the bearing flange seats properly.Repeat for the other input bearing.



Be extremely careful with thetemperature element leads extending fromthe bearings, especially when rotating.

The temperature element leads on theinput bearings exit the bearing at a locationthat would allow them to be sheared off ifthe bearing were rotated quickly in thebore. Therefore, move the lead towardsthe inside of the gearbox when rotating thebearing.

3b) Rotate the bearing in the bore until thebearing split line is horizontal, and therecessed socket head cap screws holdingthe halves together are accessible.

3c) Remove the 2 recessed socket head capscrews (#8-32UNC) holding the halves ofthe bearing together.

3d) The bearing halves are pinned together,and require some effort to separate. Usethe pry grooves, located within the lubeannulus feature, to begin the separation.

A simple pry bar may be constructedto make the separation easier. Use anallen wrench, ground down to a flat“screw-driver” tip at the end.



3e) Complete the bearing separation byholding the lower half down in the gearboxbore while pulling the upper half off.

4) Install Output Shafts (130 or 140).

4a) Generously lubricate the bore ofthe bearing lower halves with ISO Grade32 oil (see lube oil recommendations)

Do this for both of the bearings on thisshaft (151A&B or 151C&D).



4b) Orient the shaft so that the shaft ends areon the correct sides of the gearbox (101).For a single ended output shaft, this iseasily determined by the hirth connectionlocation. For double ended output shafts(hirth attachments on both ends), the shaftend with the smaller thrust runner ODpoints towards the main driver. Carefullyplace the output shaft (130 or 140) intothe bearing bores.

There is not much clearance betweenthe thrust bearings and thrust surfaces onthe shaft, so care must be taken not todamage the babbit on the thrust bearingsurfaces when installing the shaft into thebores.

4c) Generously lubricate the portion of theshaft (130 or 140) exposed in the bearingbores with ISO Grade 32 oil (see lube oilrecommendations).

Do this for both ends of the shaft, at eachbearing bore.

4d) Place the correct upper bearing half ontothe lower half, aligning the pins. Use asmall rubber mallet to lightly tap together ifrequired.




4e) Rotate the bearing so that the holes for thesocket head cap screws are facingupwards.

Be careful of the temperature elementwires when rotating the bearing, especiallywhen passing near the lube piping below.

4f) Install and tighten the 2 recessed sockethead cap screws (#8-32UNC) holding thehalves together.

4g) Rotate the bearing to the proper runningposition, where the anti-rotation pin sits inthe groove in the split line.

Repeat all of the steps in this section for bothof the bearings (151A&B or 151C&D) onthis shaft.

4f) For units with two output shafts (130 and 140), repeat all of the steps found above in thissection for the second shaft and second set of bearings.

5) Shim Output Bearings (151A and 151C) to Specified Endplay.

If endplay had been previously set, only redo this if endplay changes due to a shaft orbearing change.

5a) Ensure that both bearing flanges are fullyseated against the gearbox housing.Measure the endplay of the shaft whilefirmly pushing/pulling the shaft between thetwo thrust bearings. Required endplay is0.012”+/-.002”. If the measurement is outof this range, one of the bearings must beshimmed.



5b) Orient the bearing with the holes for thesocket head cap screws facing upwards.This may require rotating the bearing in thebore. Remove the 2 recessed sockethead cap screws (#8-32UNC) holding thehalves together.

Be careful of the probe wires whenrotating the bearing, especially whenpassing near the lube piping below.


5c) Remove the upper half of the bearing.


Keep track of which bearing halfbelongs at which position, so that when thelower halves are removed they may bekept with the proper upper halves andmarked as a matched set.

5d) Carefully remove the shaft by liftingstraight upwards.

5e) Remove the lower half of the bearing thatis opposite of the motor side (post positionA or C) for shimming. The other bearinglower half may remain in place since it willnot be shimmed.



If the bearing halves and backing plateshave not yet been matched marked, do sonow. Mark each bearing half body andend plate with a letter corresponding to it’sPost position (A, B, C, or D).

5f) Place the 2 bearing halves for shimming ona protected surface, and remove the 3socket head screws (#8-32UNC) holdingon each backing plate (and passingthrough the bearing holding on the thrustplate).

5g) Remove the end plate and thrust platefrom each half of the bearing.

Be extremely careful whendisassembling bearings with temperatureelements. Observe how the wiring isrouted within the bearing, and be sure toduplicate when reassembling bearing.



5h) The shim stock is cut in half, with throughholes for the end plate screws, to matcheach half of the proper bearing. There isone set for the CW bearings and anotherfor the CCW bearings. Be sure to removeany burrs or raised edges from the shimstock.

Install required amount of shim stockbehind thrust plate, lining up the throughholes with the screw holes.

5i) Reassemble the end plates and thrustplates to the bearing.

5j) Reinstall the lower bearing half, thencarefully reinstall the shaft back into thebearings by following all of the steps ofSection 4, “Install Output Shafts (130 &140).”

5k) Repeat all of the steps found above in thissection until the specified endplay is met.

5m) For units with two output shafts (130 and 140), repeat all of the steps found above in thissection for the second shaft and second set of bearings.



6) Install Output Bearing Probe Brackets and Probes.

6a) Assemble the axial probe bracket (154) tothe radial probe bracket (152) by installingthe socket head cap screws (1/4”-20UNC) with Locktite 242 Thread-locker(blue). Position approximately so that thetip of the bracket is not touching the shaft.Tighten only enough to hold the bracket inplace.

6b) Install the set screw (3/8”-16UNC) withLocktite 242 Thread-locker (blue), andtighten only enough to hold the axialbracket (154) in place.

6c) Adjust the axial probe bracket (154) sothat the probe is aligned approximatelywith the center of the thrust face width (onthe shaft (130 or 140)). Verify that thereis at least .060” clearance between thebottom of the bracket and the shaft (130or 140).

Tighten the 2 socket head cap screws(1/4”-20UNC) and the set screw (3/8”-16UNC).



6d) Install the radial probes into the radialprobe bracket (152) by backing off thelock nuts and threading in the probes.Gap the probes (set the probe tip to shaftdistance reading) per the manufacturer’srecommended gap voltage. Tighten thelock nuts.

6e) Install the axial probe into the axial probebracket (154) by backing off the lock nutand threading in the probe. Thrust theshaft so that the thrust runner face movestowards the probe tip (minimum gap).Gap the probe (set the probe tip to shaftdistance reading) per the manufacturer’srecommended gap voltage, so that the.012”±.002” end-play may beaccommodated. Tighten the lock nut.

6f) Route the probe and temperature elementcables along the sides of the gearbox,using the welded on studs and cableclamps. Refer to the unit outline drawingfor proper exit locations for each cable.

Ensure that cables are securelyfastened, and that there is no possibility ofcables interfering with rotating componentsor the clamping of the upper gearboxhousing. Utilize cable ties between theclamps, where required, to eliminate loosecables.



7) Install and Position Lube Oil Spray Bars (if required).

7a) The height and location of the lower spraybar is controlled by an “L” shaped pieceof tubing, sized properly at the factory forthe unit’s gear set. Ensure that all tubefittings are tight.

7b) Ensure that the drilled holes in the spraybar (there are 2 rows of 3 holes) areoriented such that they direct oil to eachside of the exiting gear mesh. The spraybar is easily oriented by loosening theclosest tube fitting, rotating the spray bar,then re-tightening the fitting.



7c) The upper spray bar is located by beinginstalled in one of two ports in the uppergearbox housing (101) above Post D. AnNPT to tube fitting connects the port tothe spray bar, and allows the bar to beeasily rotated into position. Ensure thatthe drilled holes in the spray bar (there are2 rows of 3 holes) are oriented so thatthey direct oil to each side of the exitinggear mesh. The other port must beplugged.

If the spray bar is located in the wrongport, it may damage the gear when theupper housing is assembled to the lower.The spray bar should remain in the factoryset location, or it should be assembledthough the inspection window afterassembling the upper and lower housings.



8) Install Input Shaft Assy (120).

8a) Using a suitable hoist andconnecting member, lift the input shaftassembly (120) (approximately 1000 lbs).The holes in the gear may be used toattach a suitable lifting strap.

8b) Generously lubricate the bore of thebearing lower halves with ISO Grade 32oil (see lube oil recommendations)

Do this for both of the input bearings(151E and 151F).

Make sure the input bearing flangesare seated against the gearbox, becausethere is not much clearance between thethrust bearings and thrust surfaces on theshaft. Care must be taken not to damagethe babbit on the input thrust bearingsurfaces when installing the shaft into thebores.

Also, care must be taken to avoid anyimpact with the hardened gear teeth duringthe assembly.

8c) Generously lubricate the portion of theshaft (120) exposed in the bearing boreswith ISO Grade 32 oil (see lube oilrecommendations).

Do this for both ends of the shaft, at eachbearing bore.



8d) Place the correct upper bearing half ontothe lower half, aligning the pins. Use asmall rubber mallet to lightly tap together ifrequired.

Do this for both of the bearings (151E and151F) on this shaft (120).

8f) Rotate the bearing so that the holes for thesocket head cap screws are facingupwards.

Be very careful of the temperatureelement wires when rotating the bearing,especially when the exiting wires pass bythe split line, since their exit location makesit possible for them to be sheared off.

8g) Install and tighten the 2 recessed sockethead cap screws (#8-32UNC) holding thehalves together.

8h) Rotate the bearing to the proper runningposition, where the anti-rotation pin sits inthe groove in the split line.

Repeat all of the steps in this section for bothof the bearings (151E and 151F) on thisshaft (120).



9) Install Input Bearing Probe Brackets and Probes.

9a) Assemble the key phasor probe bracket(153) to the radial probe bracket (152) byinstalling the 2 socket head cap screws(1/4”-20UNC) with Locktite 242 Thread-locker (blue), and tightening.

9b) Install the radial probes into the radialprobe bracket (152) by backing off thelock nuts and threading in the probes.Gap the probes (set the probe tip to shaftdistance reading) per the manufacturer’srecommended gap voltage. Tighten thelock nuts.

9c) Install the key phasor probe into the keyphasor probe bracket (154) by backingoff the lock nut and threading in the probe.Gap the probe (set the probe tip to shaftdistance reading) per the manufacturer’srecommended gap voltage. Tighten thelock nut.

10) Apply Sealant to Split Line Surface of Lower Gearbox Housing (101).

10a) Thoroughly clean the split line surface oneach half of the gearbox housing (101) ofold gasket sealant, oxidation, debris,residual oil, etc. (see section 1).



10b) Apply Permatex #2 Gasket Sealant, NonHardening #30515, only to the split linesurface of the lower gearbox housing(101), as follows;

Apply a bead of sealant around the outerand inner edges of each split line surface.Run a bead around all of the mountingholes (this prevents pressurized oil thatmay enter the split line from migrating upthe fasteners). Maintain at least a 1/4”distance from the edges and holeswherever possible.

10c) On each side of the input shaft bearingbores there are lube grooves that have a“dead-end” before reaching the outboardbore face. This area requires sealantaround the end of the groove, and alongthe bore face edges, which are beyondwhere the cover o-ring seals (the o-ringcover o-ring seals within the bearing bore).



11) Assemble Upper and Lower Gearbox Housings (101).

11a) Install “All-Thread” guide studs,into the center threaded holes at the endsof the lower housing (101) split line (seenext photo). The length of these guidestuds should be approximately 23” long,or enough to ensure that the studs engagethe upper housing before reaching theheight of the bull gear profile. This willkeep the assembly aligned as the upperhousing is lowered onto the lower housing.

11b) Using a suitable hoist andconnecting member, lift the upper housing(101) (approximately 1000 lbs) by thelifting eyes (851) at the top of the upperhousing.

11c) Push all of the bearings towards their respective thrust runners (towards the centerof the gearbox) to allow clearance as the upper housing is lowered onto the lower housing.Be sure that all of the bearing anti-rotation pins are seated in the split line grooves.

Care must be taken to avoid any impact with the hardened gear teeth during theassembly.



11d) Lower the upper housing down onto theguide studs by aligning them with thematching holes on the upper housing(101).

Carefully continue lowering theupper housing, being sure that alltemperature and vibration leads are clearof the mating surfaces, including the upperbearing bores.

Remove the “All-Thread” guide studs fromthe assembly.

11e) Ensure that all residual sealant has beencleaned from taper pin holes in both theupper and lower housings (101), as it willtend to extrude into the holes when theupper is placed onto the lower. Insert thefive taper pins (560) into theircorresponding locations. These shouldhave a nut and washer as part of theirassembly.

11f) Tap the 5 taper pins (560) securely intoplace using a rubber mallet. The nutshould be backed off enough so that whenthe pin is tapped into place, there is stillclearance between the nut and washer.



11g) Lubricate the threads of the 10 split linescrews (557) (3/4”-10UNC) with an ISOGrade 32 oil. Install the 10 split linescrews (557) with the 10 washers (657)into the gearbox housing (101) until fingertight.

11h) Lubricate both ends of the 4 input bossstuds (558) (3/4”-10UNC) and the 8output boss studs (559) (3/4”-10UNC)with an ISO Grade 32 oil. Install all 12studs into their respective positions untilthey bottom out in the lower housing.Install the 12 washers (658 and 659),followed by the 12 nuts (758 and 759)(3/4”-10UNC) until finger tight.

11j) Snug down the 10 split line screws (557)and the 12 stud nuts (758 and 759), thenagain tap the 5 taper pins (560) securelyinto place.

Torque the 10 screws (557) and the 12stud nuts (758 and 759) to 200 ft-lbs, byprogressing in 70 ft-lb increments. Startwith those closest to the input shaft (120),and work outwards, while alternatingfasteners on each side, as shown below:



12) Assemble Retainer (162) to Gearbox Housing (101).

12a) Lubricate the o-ring (956) with a siliconelubricant, and install on the retainer (162).

12b) Install the retainer (162) onto thegearbox housing (101) by placing over theinput shaft (120) through the hole near theOD NPT port. The retainer o-ring shouldbe facing the housing. Carefully align theretainer boss with the bore on the housing,and push in until the retainer is flush withthe housing.

12c) Apply Anti-Seize lubricant to the threadsof the 4 retainer screws (556) (5/8”-11UNC), install into the housing, andtorque to the value specified in Table 1.



13) Assemble Adapter Flange (161) to the Lube Pump (160)

To prevent the cover from sliding downthe slope of the housing, and riskingdislodging of the o-ring, first insert the 2upper screws and washers to hold thecover in place.



IV. Gearbox Disassembly

This section provides procedures for disassembly of the LF-2000 gearbox, with the primaryobjective of removing the bearings. The gearbox has been designed with several innovativefeatures that facilitate disassembly and servicing. The first is being able to remove the upperhousing, providing access to the gearbox internals, without removing the compressor ends, sincethey are mounted only to the lower gearbox. The second is being able to remove bearingswithout first removing the shafts that they support (while also leaving the compressor endsmounted to the gearbox). This is accomplished by a split bearing design.

Follow your organization's lockout/tag-out instructions before working on thecompressor. Failure to follow adequate lockout/tag-out procedures could result in severepersonal injury or loss of life.

Use proper lifting devices and methods. Failure to do so could result in serious injury toyou or others.

A summary of the disassembly steps is listed below, followed by detailed descriptions andimages. Item numbers are provided in parenthesis. Refer to the Compressor Gearbox drawingCG01GC03 for a cross-section view with item numbers identified, and the unit BOM for partnumbers corresponding to each item number:

1. Remove the Output Shaft Covers (181) from the Gearbox Housing (101).

2. Remove the Front Input Shaft Cover (102) from the Gearbox Housing (101).

3. Unfasten the Retainer (162) from the Upper Gearbox Housing (101).

4. Remove the Upper Gearbox Housing (101) from the Lower Gearbox Housing (101).

5. Remove/Replace the Input Bearings (151E & F).

6. Remove/Replace the Output Bearings (151A & B, or C & D).



Detailed Description of the Gearbox Disassembly:

Detailed descriptions of the disassembly steps are listed below. Item numbers are provided inparenthesis. . Refer to the Compressor Gearbox drawing CG01GC03 for a cross-section viewwith item numbers identified, and the unit BOM for part numbers corresponding to each itemnumber. Disassembly may be done up to a certain point with the compressor cases mounted tothe gearbox:

1) Remove the Output Shaft Covers (181) from the Gearbox Housing (101).

This will be done for all the post locationswhich do not have compressor ends.

1a) Remove the 6 cover screws (555) andwashers (655), then remove the cover(181). Jacking screw holes, which acceptthe cover screws, are provided to facilitateremoval.

If desired, the covers may be “backedoff” rather than removed. This is done byremoving the 3 screws which insert intothe upper gearbox housing, while “backingoff” the remaining 3 lower screws about ahalf inch. Then the cover may also be“backed off” away from the upperhousing.



2) Remove the Front Input Shaft Cover (102) from the Gearbox Housing (101).

2a) Remove the 6 cover screws (550) andwashers (650), then remove the cover(102). Jacking screw holes, which acceptthe cover screws, are provided to facilitateremoval.

If desired, the covers may be “backedoff” rather than removed. This is done byremoving the 3 screws which insert intothe upper gearbox housing, while “backingoff” the remaining 3 lower screws about ahalf inch. Then the cover may also be“backed off” away from the upperhousing.



3) Unfasten the Retainer (162) from the Upper Gearbox Housing (101).

3a) Remove the upper 2 retainer screws (556)which fasten the retainer (162) to theupper gearbox housing (101), and loosenthe lower 2 retainer screws (556) whichfasten the retainer (162) to the lowergearbox housing (101).

The lube pump retainer (162) must bebacked off slightly to prevent damaging theface o-ring (956) when removing theupper housing (as well as when replacingit).

3b) The lube pump piping, connected by twoSAE type flanges to the lube pump (160),may either cause the retainer (162) toback off when loosened due to pipe strain,or it may prevent the retainer from backingoff due to pipe rigidity. The separation gaspiping at the top of the retainer may alsorestrict retainer movement. If the retainerdoes not back off when loosened,disconnect the SAE flanges, and theseparation gas piping if necessary, andslide the retainer and lube pump awayfrom the gearbox about ½”.

CAUTION: Before reinstalling the upper gearbox housing (101), make sure that all thecovers and retainer that were backed off or removed in the previous steps remain backedoff or removed to provide clearance when lowering the upper housing back into place. Usecaution to ensure that none of the o-rings on these components are damaged during thereassembly. The covers and retainer should be reinstalled only after the upper gearboxhousing is reassembled.



4) Remove the Upper Gearbox Housing (101) fromthe Lower Gearbox Housing (101).

4a) Loosen the 10 split line screws (557) andthe 12 stud nuts (758 and 759), andtighten down the nuts for the 5 taper pins(560) so that the taper pins disengage.

4b) Remove the 10 split line screws (557), the12 stud nuts (758 and 759), and the 5taper pins (560).

(Photo shows lifting off already in process) 4c) Install “All-Thread” guide studs, providedin the Tool Kit, into the center threadedholes at the ends of the lower housing(101) split line. Ensure that the length ofthese guide studs are long enough toensure that the studs remain engaged in theupper housing until the bull gear is cleared.



Care must be taken to avoid anyimpact with the hardened gear teeth duringthe disassembly.

4d) Lift the upper gearbox housing(101) off of the lower gearbox housing(101), utilizing the lifting instructionprovided in Section A.

4e) Remove the “All-Thread” guide studsfrom the lower gearbox housing.

5) Remove/Replace the Input Bearings (151E & F).

(Pictures show assembly without input shaft,but instructions explain bearing removal withshaft in place)

Be extremely careful with thetemperature element leads extending fromthe bearings, especially when rotating.

The temperature element leads on theinput bearings exit the bearing at a locationthat would allow them to be sheared off ifthe bearing were rotated quickly in thebore. Therefore, move the lead towardsthe inside of the gearbox when rotating thebearing.



Use a lifting strap and crane tosupport the weight of the input shaftassembly (120) near the bearing beingremoved. Otherwise the bearing will notbe able to be rotated, and the bearing maybe damaged.

5a) Rotate the bearing in the bore until thebearing split line is horizontal, and therecessed socket head cap screws holdingthe halves together are accessible.

5b) Remove the 2 recessed socket head capscrews (#8-32UNC) holding the halves ofthe bearing together.

5c) The bearing halves are pinned together,and require some effort to separate. Usethe pry grooves, located within the lubeannulus feature, to begin the separation.

A simple pry bar may be constructedto make the separation easier. Use anallen wrench, ground down to a flat“screw-driver” tip at the end.



5d) The top half of the bearing may be liftedoff of the lower half of the bearing and theinput shaft (120).

5e) In order to remove/replace an entirebearing with the input shaft (120) in place,one half of a bearing must always besupporting the shaft. Therefore, afterremoving the top half, a new top half mustbe assembled to the old bottom half, thenthe assembly must be rotated to removethe old bottom half. Then finally the newbottom half may be assembled to the newtop half, and the bearing assembly may berotated into position.

6) Remove/Replace the Output Bearings (151A & B, or C & D).

Be extremely careful with the temperature element and vibration probe leads extendingfrom the bearings, especially when rotating. When the bearing is rotated with probesmounted in brackets, the lube supply pipe to the bearing will be very close to the probes

6a) Orient the bearing with the holes for thesocket head cap screws facing upwards.This may require rotating the bearing in thebore. Remove the 2 recessed sockethead cap screws (#8-32UNC) holding thehalves together.

To rotate the bearing it may benecessary to support the weight of theshaft (130 or 140) by hand.

Be careful of the probe wires whenrotating the bearing, especially whenpassing near the lube piping below.




(Pictures show assembly without output shaft,but instructions explain bearing removal withshaft in place)

6b) The bearing halves are pinned together,and require some effort to separate. Usethe pry grooves, located within the lubeannulus feature, to begin the separation.

A simple pry bar may be constructedto make the separation easier. Use an allenwrench, ground down to a flat “screw-driver”tip at the end.

6c) The top half of the bearing may be liftedoff of the lower half of the bearing and theoutput shaft (130 or 140).

6d) In order to remove/replace an entirebearing with the output shaft in place, onehalf of a bearing must always besupporting the shaft. Therefore, afterremoving the top half, a new top half mustbe assembled to the old bottom half, thenrotate the assembly to remove the oldbottom half. Then finally the new bottomhalf may be assembled to the new top half,and the bearing assembly may be rotatedinto position.

6e) For units with two output shafts (130 and140), repeat all of the steps of this sectionfor the second set of bearings.

6f) Be sure to verify the shaft endplay byrepeating Step 5 in the Gearbox Assemblyinstructions found above.
