TRANSPORT & STORAGEInspection

Immediately inspect your Sundyne product upon receipt of the equipment. Check for any damage, which may have occurred during

shipment. Notify the carrier and Sundyne immediately if damage is evident.

Storing Your Bearing Box Short-Term

If your Sundyne bearing box is not to be installed immediately, protect it from exposure to moisture and dust. Do not remove the factory

installed shipping covers for casing flanges and seal ports, if applicable. Ensure that the shipping covers be kept securely in place.

Storing Your Bearing Box Long-Term

In addition to the precautions in the short-term section above, additional precautions are required for long-term storage.

If your Sundyne bearing box will not be operated for a period of time exceeding six months from the date of shipment, long-term storage conditions must be met to ensure minimum corrosion damage to components.

Note: Sundyne does not accept liability for equipment damaged during the storage period. Sundyne does not guarantee the quality of equipment during and after the storage period.

To ensure the original quality of the Sundyne bearing box after storage, all components must be inspected by an authorized Sundyne service engineer. Components that are not manufactured by Sundyne must be inspected by its own manufacturer.

Note: Any inspection fees are the sole responsibility of the purchaser.

Factors, which affect the quality of a Sundyne bearing box, when stored, are:

• Humidity

• Temperature

• Surrounding chemicals

Long-term storage methods must prevent damaging conditions from making contact with the internal components of the equipment. When the equipment is stored in strong chemical environments or near salt water, protection must occur immediately upon receipt of the equipment.

Recommended Long-Term Storage Procedures Sundyne recommends that you do the following to prevent damage to your bearing box during long-term storage:

1. Store your bearing box only in an indoor, climate-controlled building. These conditions will maintain constant temperature and humidity.

2. Perform inert gas purging of component internals.

3. Use desiccant bags.

Note: Because long-term storage of equipment is of a highly critical nature, it is recommended that Sundyne be contacted to provide more details on the above procedures.

LUBRICATION Lubrication Options

There are three lubrication options available for the Sundyne bearing box. All lubrication options are available with a standard shaft or a high power fat shaft for motors larger than 60 hp. Grease Lube These bearings are packed with grease and shielded. They require no service for the life of the bearings. Pressure Lube ISO VG 46 mineral oil or equivalent synthetic oil is recommended. Oil Mist The oil mist lubrication system is to be provided by the user. Air flow rates, oil flow rates, and oil type are specified by the supplier of the oil mist system equipment. Sundyne recommends using reclassifiers rated for 0.18 SCFM @ 20 in H2O. The exploded view, later in this manual, identifies the two ports to be used for the oil mist inlets and the one port to be used for the return to the oil mist system.

Pressure Lube - Lubricator

Correct installation, adjustment, and operation of the lubricator are the keys to a successfully operating pressure lube bearing box. Please read and follow the instructions carefully.

1. Unscrew the fasteners and remove the wire guard cage.

2. Loosen the reservoir locking thumb

screw enough to remove the reservoir and level adjuster mechanism from the lubricator base.

3. Inspect the parts to be sure they are

free from debris and contaminants. If necessary, remove burrs from the inside of the connecting pipe to ensure oil can flow freely.

4. Attach the lubricator to the lube pump

housing with the connecting pipe. Apply pipe thread compound on all threaded connections, before tightening.

5. Check centerline of lubricator base to

ensure it is parallel to the bearing box housing. Most importantly, the connecting pipe must be level for the lubricator to work properly. Make adjustments if necessary.

6. Remove the oil level adjuster

mechanism from the base and set oil level by threading the top adjuster arm up to within one to two threads from the top thread. Lock in place by threading the lower adjuster arm up against the upper adjuster arm. Hand tighten only.

Caution: The oil level should never be set

above the top edge of the lower bearing housing flange. Reference Figure 1.

7. Fill the reservoir, invert and place

reservoir over the lubricator base. Ensure the thumb screw lock for the reservoir base is backed off enough to avoid interfering with the seating of the reservoir.

8. Use 3 full volumes of the reservoir. This

will leave the reservoir partially full, after inverting the third volume into the lubricator base. As the bearing box



5

sump oil level drops, oil will automatically be drawn from this reservoir.

Note: Never use the lubricator base as a fill

spout; always fill using the reservoir.

9. When the appropriate oil level is reached, the oil level in the reservoir will stabilize.

Additional oil should only be added if the reservoir level is less than 1/3 full. Note: The appropriate quantity of oil required

for the bearing box is 0.67 quarts (0.63 liters). Additional oil is required to fill the connecting pipe and reservoir.

10. Lock the reservoir assembly in place using the thumb screw.

11. Replace the wire guard cage.

Once the lubricator has been properly adjusted, no further adjustments are necessary, only a periodical filling of the lubricator’s reservoir is required. Note: If the oil level is too high, churning

occurs causing an increase in temperature resulting in reduced oil life. If the oil level is too low, excessive heating or premature bearing failure will occur. Investigate these problems immediately and correct them so as to avoid extensive machine damage and costly shut downs.

Inspection and Cleaning

Inspect All Parts Prior to Reassembly 1. Housing preparation:

1.1 Make sure all passages are drilled through and water can flow continuously through all port holes. 1.2 Check all passages and port holes with a flashlight to ensure they are all free from burrs, chips,

and other contaminants. 1.3 Polish all nicks, dings, and scratches on mating and critical surfaces with a fine stone.

2. For each machined part, remove all sharp edges completely from lead-in chamfers, keyways, and

retaining ring grooves.

3. Thoroughly clean and dry all parts prior to assembly, according to industry standards, to remove all grease, oil and foreign particles. All surfaces shall be clean, dry, and free of contamination.

4. Verify that the lube jet (11) has the hole drilled completely through and that the passage is not blocked

by contaminants.

5. Inspect bearings for smooth rotation, and signs of wear on outer and inner races.

Replace bearings if:

• They have been in operation for over three years

• If rotation is not smooth

• If outside or inside diameters are worn

Note: Do not tamper with or attempt to remove the shields on the grease packed bearings. Only replace bearings with Sundyne approved replacement bearings. Non-approved bearings may jeopardize the mechanical integrity of the bearing box and pump assembly.

6. All machined surfaces should be lightly oiled before assembly to protect from rusting. 7. Inspect the seals to ensure they are clean and not damaged including the o-ring condition. 8. Sundyne recommends replacing all o-rings whenever the unit is disassembled.

Hole should be completely through



13

Assembling the Grease Lube or Oil Mist Bearing Box STEP 1 Press the upper and lower bearings (22 & 23) onto the shaft (1) using a press which contacts only the inner race. The bearing seating surface should be lightly oiled before pressing on the bearings.

Note: For the grease lube model the bearings

are shielded and for the oil mist option the bearings are open conrad style.

Note: Damage to the bearing can occur by

pressing against the outer raceway. STEP 2 Place the bearing lock washer (28) on the shaft (1) and thread the bearing lock nut (27) onto the shaft to secure the upper bearing (22). Note that the bevel side of the lock nut should be oriented towards the bearing. A tang on the lock washer should be placed into the keyway on the shaft.

Note: Tighten the lock nut by hand tightening

only. The lock nut should be as tight as possible by hand.

After tightening the lock nut, bend one tang of the lock washer into a slot on the lock nut. STEP 3 Place the lower bearing retainer (24) into an oven heated to 400°F (204°C) for 30 minutes.
