SECTION 6. TRANSMISSION AND RELATEDCOMPONENTSThis section will detail the servicing procedures on the transmission assembly whichhas splines formed on the agitator drive shaft. An "O" ring is installed on the shaft justabove the center post to provide a center post seal when the agitator is installed.


CENTER POST ASSEMBLY

The center post assembly consists of aplastic center post. A nylon agitatorbearing slips over the lower portion onthe center post body.

The center post assembly is secured tothe basket hub assembly by the spinbasket, and to the agitator shaft. Asmall rubber gasket is installed in agroove on the bottom flange of the centerpost, and a foam gasket is placedbetween the bottom of the spin basketand the basket hub assembly.

The center post can be removed afterremoving the spin basket, and the agita-tor shaft "O" ring.

The die-cast bearing and seal housingslips over a machined area on the lowerdrive tube. The basket hub assemblythreads downward over the drive tubeand secures the bearing and seal hous-ing.

The spin bearing and the tub seal areinstalled in a cavity in the center of thehousing. The sheet metal tub support isattached to the under side of the housingwith three (3) mounting screws. Thespin bearing has been pressed into theunderside of the housing cavity and issecured by the tub support.

The center of the tub assembly mounts tothe upper flange of the housing with a tubgasket and a tub seal installed between.The bottom of the tub sits on, and isattached to, the tub support.

BEARING AND SEAL HOUSING

REMOVAL:

1. Disconnect the unit from the powersource.

2. Remove the agitator, spin basket,tub assembly, and center post.

3. Remove the Seal nut with 2202898 and35-2968

4. Remove the basket hub assemblyby turning it in a counterclock-wise direction, using tool number35-2968.

5. Remove the suspension springs toprevent damage to the tub bracesand unbolt the tub braces from thetub support.

6. To remove, lift up on the bearingand seal housing with tub supportattached.

7. To disassemble tub support fromhousing, remove mounting screwsfrom underside.


TUB SEALThere are 2 Tub Seal designs, the originalFace Seal and the new Triple Lip Sealintroduced at series 17.

Face SealThe tub Face Seal consists of the seal faceand seal body.

NOTE: All parts of the seal must bereplaced if either of the sealing surfacesare damaged.

The seal face fits into a recess in the under-side of the basket hub assembly. Also, theseal body installs in the cavity on the top sideof the bearing and seal housing. The spinbearing is located in a cavity on the under-side of the bearing and seal housing.

Each of the two (2) sealing parts, the sealface and the seal body, have sealing faceswhich are brought into contact with oneanother when the basket hub assembly isthreaded down on the drive tube. Thesprings in the seal body exert pressure tokeep the sealing faces in contact.

Triple Lip Seal Triple Lip Tub Seal

Assembly used with the21001867 Hi-TorqueTransmission Assembly.

NOTE: Sealing surfaceare on the O.D. of thealuminum spinner hubwith no seal in the hubcavity.

NOTE: The Triple Lip Seal and Bearing is only used with the High Torque Dual Drive transmission. The 21001867 High Torque service transmission will include a Triple Lip Seal and Bearing for proper matching of parts. The High Torque transmission will have An “HT” next to the date code for field identification purposes. Do not use 21001868 Seal kit on older transmissions not de signed to operate at higher torque levels. Always refer to Parts Pro or Microfiche for proper parts ordering. The 21001868 Triple Lip Seal kit will include a sticker to be placed on the Outer Tub of the washer to identify the washer has been modified with a High Torque Transmission and Triple Lip Seal kit.

TUB SEAL REPLACEMENT:

Should the tub seal begin to leak or developexcess seal drag, it must be replaced. Theservice replacement seal includes all theparts necessary to replace the entire seal.Be sure to replace all parts of the seal even ifonly one part is found to be damaged.

NOTE: If the tub seal is being replacedbecause it has begun to leak, the spinbearing is probably defective also andshould be replaced. To replace the spinbearing, the bearing and seal housingmust be removed as previously de-scribed. This also allows access to thetub seal for removal and replacement(refer to steps 2 and 3 below when in-stalling).

Removal and replacement of the tub sealcan ONLY be accomplished as follows:

1. Follow steps 1 through 3 for theface seal

NOTE: For Triple Lip Seal special instuction,see next column

FACE SEAL 2. Before installing the new seal, coat

the mounting recess of the housingswith silicone grease (part number203959). This will allow the sealbody and seal face to slip into posi-tion.

NOTE: MAKE SURE NO GREASECOMES IN CONTACT WITH THEMATING SURFACES OF THE SEAL.

SPIN BEARINGThe spin bearing is installed in a cavity onthe underside of the bearing and sealhousing. It is also press fitted and bot-toms out on the cavity shoulder. It isfurther secured in place by the innerdiameter of the tub support.

SPIN BEARING REPLACEMENT:


2. Remove the bearing and seal hous-ing and the tub support as previ-ously described.

3. Remove the seal body from thehousing cavity.

4. Press the spin bearing out ofthe cavity from the opposite side ofthe housing.

5. When installing the replacementbearing into the housing cavity, besure to press against the outer raceof the bearing to avoid damage tothe bearing shield and causing pre-mature failure.

Triple Lip Seal (056016) grease

NOTE: Do not use any agent other thanalcohol to clean the mating surface. Donot use any lubricant other than SiliconeGrease, part number 203959.

3. Make sure both seal mating surfacesare free of foreign matter, then cleanboth surfaces with an alcohol satu-

rated cloth.

TRIPLE LIP SEAL 1. Apply center seal grease (056016) to

Seal Nut and Triple Lip Seal beforeinstalling.

Seal Nut (056016) grease


onto the bottom of the hub. The purposeof the pulley and cam arrangement is todrive the clutch assembly during theagitate and spin cycle, and to disengagethe brake assembly during the spin cycle.

The drive pulley slips over the drive shaftand rests against a series of washers, athrust bearing, and a large washer typespacer. The spacer locates against thebottom of the brake rotor and liningassembly. (See the illustration onpage 6-6.)

The lower cam slips over the end of thedrive shaft where splines formed in thecam engage with mating splines on thedrive shaft end. This imparts a directdrive from the cam to the drive shaft.A shoulder molded on the bottom of thepulley hub engages "dogs" formed on thesides of the lower cam, and will drive itand the drive shaft in either direction.

A washer and retaining ring secure thepulley and cam on the drive shaft. Aplastic dust cap snaps to the undersideof the pulley to keep the cam surfacesclean.

OPERATION:

When the drive pulley rotates CLOCK-WISE, the upper and lower cams aredesigned to nest together which allowsthe drive pulley to remain in position onthe drive shaft. The break remains en-gaged and the drive pulley will turn thelower cam and drive the shaft to causethe transmission to agitate.

When the drive pulley rotates COUNTER-CLOCKWISE, the upper cam and pulleyride up the lower cam approximately 3/16of an inch before the driving shoulders onthe pulley hub engage the "dogs" on thelower cam.

This causes the top of the pulley hub topush against the spacer which com-presses the brake spring and lifts thebrake rotor and lining assembly off thebrake stator. The brake is disengagedand the pulley will turn the lower camand drive shaft to cause the transmissionto spin.

DRIVE PULLEY AND CAMS

The drive pulley and cam is located belowthe brake assembly on the drive shaft.

Models are equipped with a plastic drivepulley which has the upper cam molded


Spacer

BrakeStator

Original Thrust Washer Design


REMOVAL:


2. Tip the unit over and remove thedrive belt.

3. Remove the dust cap from the underside of pulley.

4. Remove retaining ring and washerfrom end of drive shaft.

5. Firmly pull lower cam off the driveshaft splines, then slide the otherparts off the shaft. This will alsoallow access to the brake assemblyfor removal.

REASSEMBLY:

After reassembling the components onthe drive shaft, it will probably be neces-sary to pull down on the shaft to take theend play out of it before the thrust washerand retaining ring can be reinstalled.

NOTE: Each time the cams are reas-sembled on the drive shaft, the point inthe cam rise where the brake disengagesthe stator should be checked and ad-justed as necessary.

Reference marks have been moldedaround the bottom outer edge of thelower cam as an aid in checking the pointof brake disengagement (see followingfigure). Each mark, from right to left,represents approximately .010 of an inchcam rise.

To Check Brake Disengagement:

1. Manually rotate the drive pulley in aslow counterclockwise direction until

If the position of the pulley hub shoulderis not within these parameters and thebrake has started disengaging, adjust-ment is required.

To Adjust Brake Disengagement:

1. If the position of the pulley hubshoulder is less than 3 referencemarks, remove the standard (.062thickness) thrust washer and replaceit with a thinner (.032 thickness)thrust washer (part number 35-2132).Recheck disengagement.

2. If the position of the pulley hubshoulder is more than 9 referencemarks, add a 35-2132 thrust washer(.032) to the standard thrust washerand recheck disengagement.

the brake starts to release and thetransmission begins to turn.(See following figure).

2. Counting the reference marks on thelower cam from right to left, thepulley hub shoulder should be posi-tioned between reference marks 9and 3, with 6 being the median.(Shown in the following figure).


BRAKE ASSEMBLY

The brake assembly is located inside thedomed area of the suspension housingand consists of the following compo-nents: brake spring retainer, brakespring, rotor and lining assembly, andthe brake stator.

The brake assembly, as well as the snub-ber, is held in position by the brake statorwhich is secured to the underside of thesuspension housing by six (6) mountingscrews.

Spring pressure forces the rotor andlining assembly down on the brake statorand prevents the transmission fromturning during agitation.

As stated previously, the drive pulley andcams provide a cam action which raisesthe drive pulley during the counterclock-wise (spin) direction of the motor. Whenthe drive pulley hub travels upward, itcompresses the brake spring and movesthe rotor and lining assembly up the drivetube disengaging it from the stator. Thetransmission is now free to spin.

Splines in the brake rotor hub mesh withsplines on the drive tube end to providepositive vertical movement for the rotorand lining assembly. The splines aregreased for ease of movement.

2. Remove the drive pulley and camcomponents as previously de-scribed.

3. Using brake removal tool number 35-2442, proceed as follows:

• Pull out and remove "U" retainerfrom tool.

• Slip the splined end of the driveshaft into hole located in the toolinner plunger.

• Looking at the side of the tool,align slots on tool barrel and holesin tool plunger between splinesand chamfered shoulder of shaft.

• Slip "U" retainer through tool slotsand holes capturing the driveshaft behind the chamfered shoul-der.

NOTE: Be sure "U" retainer iscompletely through both sides oftool.

• Tighten tool nut to compressbrake spring until transmissionturns freely.

• Remove the six (6) screws whichsecure the brake stator and snub-ber to the underside of the sus-pension housing.

• Loosen tool nut until the brakespring reaches its free length.

• Remove "U" retainer from tool andremove tool from drive shaft.

• Remove brake components.DISASSEMBLY:


The brake assembly has a compres- sive spring force of approximately 200 pounds. See the following in- structions for disassembly.

TRANSMISSION HOUSINGASSEMBLYThe die-cast aluminum transmissionhousing has four studs pressed into itsupper region. The studs provide mount-ing for the two crank and two clustergears. The top cover is threaded into thelower housing. A sealant is used on thethreads as a gasket material. A steeldrive tube with a splined end is pressedinto the bottom of the transmission hous-ing. A sleeve bearing is installed in thelower I. D. of the drive tube. Anotherbearing is pressed into the lower housingabove the drive tube. These bearingsprovide a path for the drive shaft to ridein. An oil seal is installed in the bottom ofthe drive tube. The oil seal can be re-placed as a separate part.

5. Remove the cone-shaped end fromthe seal protector tool and slide thetool, drive washer, and new seal overthe drive shaft up to the seal cavity.

6. Slide the transmission seal driver(tool number 14242) over the driveshaft until it makes contact with thedrive washer. Use the impact sleeveof the tool to "tap" the seal into theend of the drive tube.

Oil Seal Replacement:

The oil seal is located in the spline end ofthe drive tube. The seal can be replacedwithout removing or disassembling thetransmission, as outlined below:


2. Remove the brake assembly toaccess the seal.

3. Use a thin, flat bladed screwdriver tocarefully pry the old seal out.

4. Place the drive washer (tool number14242) and the new seal overthe seal protector.

The lower bearing assembly consists of aball type bearing which has been installedin an aluminum die-cast housing. Thetransmission assembly must be removedfrom the washer cabinet before the lowerbearing assembly can be replaced.

The lower bearing assembly provideslateral support for the drive tube andshaft against the tension of the drive belt.The top of the suspension housingis attached to the underside of the lowerbearing assembly.

REPLACEMENT:

Because the lower bearing assembly has been pressed onto the drive tube

under approximately 1,000 pounds of pressure, a puller must be used to remove it. However, the puller forcing screw must not be used on the end of the drive shaft or the clutch assembly could be damaged. Instead, a simple pipe and cap as-

sembly can be made to slip over the drive shaft, with end clearance, and rest against the end of the drive tube.

LOWER BEARING ASSEMBLY

IMPORTANT


5. Slip the pipe and cap assembly overthe drive shaft and up against thedrive tube.

6. Using a puller with at least a 3 1/2inch spread and sufficient reach toencompass the pipe and cap assem-bly, remove the lower bearing as-sembly.

NOTE: When installing the new lowerbearing assembly, be sure to driveagainst the inner race only to avoiddamaging the bearing shield whichcould cause premature failure.

The puller forcing screw is used on theend of the pipe cap which directs theforward thrust of the puller to the bottomof the drive tube.

REMOVAL:


2. Remove the transmission from thewasher cabinet.

3. Remove the cams, drive pulley, andbrake assembly.

4. Remove the three (3) screws whichsecure the suspension housing tothe lower bearing assembly.


NOTE: Before starting these tests, thewasher should be operated in the agita-tion cycle with hot water for about two(2) minutes, and then for two (2) min-utes in a spin cycle. This warms up thetransmission oil and the spin drive traincomponents.

Available Torque

Place a 1/2 inch socket and torquewrench on the agitator retaining bolt.

Depress the safety spin switch to allowthe washer to operate in the spin cycle,then while reading the torque allow thewrench to turn slowly (about 6 R.P.M.)through a complete 360 degree cycle.The reading should be between 18 and25 inch pounds throughout the complete360 degree rotation of the wrench.

Listed below are most of the servicecomplaints which would normally becaused by a malfunctioning componentof the transmission assembly.

DIAGNOSING TRANSMISSION PROBLEMS

Oil Leaks

Oil leaks can be caused by faulty seals,gaskets, or a loose fitting stud.

Slow Spin Speed

Slow spin speed can be caused by abinding tub seal and/or bearing, brakerotor assembly not disengaging properly,a slipping clutch spring, or an off balanceclothes load. The test that follows can beused to isolate the problem.

TORQUE TESTING:

A quick test of the efficiency of the spinoperation components can be made byplacing a 3 1/2 pound weight, such as abag of sand, in the washer basket andstarting the machine in the spring cycle.If the basket appears to reach full spinwith the weight, the machine compo-nents are performing as intended. If thebasket does not attain full spin speed, thetorque test procedures as outlined in thefollowing paragraphs should be per-formed to determine the problem.

The torque available to drive the spinbasket is determined by the amount ofdrag or resistance presented by the tubseal and spin bearing, deducted from theinput torque imparted to the transmissionhousing assembly by the clutch assembly.

The Following Torque Tests Will Allow aProblem in the Spin Drive Train to bePinpointed:


If the reading is still over 4 inch pounds,the tub seal and/or spin bearing is bind-ing and should be replaced.

If the available torque reading is below18 inch pounds and the drag torquereading is not over 4 inch pounds, followthe procedure for checking the clutchassembly as to its input torque.

Input Torque

NOTE: It will be observed that thereadings used to check the input torqueare slightly lower than the readings usedto check the available torque. The rea-son for this is when the brake is disen-gaged, as in checking the availabletorque, the compressed brake springexerts a downward force on the bottomof the clutch hub and thrust washers.This keeps the clutch spring from slip-ping quite as readily as in checking theinput torque where the brake is engagedand the downward force on the clutchhub is minimized.

To check the input torque, remove thedrive pulley and position the washer sothe scale on the torque wrench can beread when it is placed on the input (drive)shaft. Attach the torque wrench adapterfirmly to the shaft, place the wrench inthe adapter and slowly rotate the wrenchin a counterclockwise direction. A prop-erly operating clutch assembly will have atorque reading between 17 and 20 inchpounds.

If the input torque is less than 17 inchpounds, the clutch assembly is defectiveand must be repaired or replaced.

If the input torque exceeds 20 inchpounds, remove the clutch assemblyfrom the transmission. Secure the drive

If the torque readings are within theselimits, the washer is performing properlyand any slow spin complaints can beassumed to have been the result of off-balance loads.

If the torque reading exceeds 25 inchpounds, the input torque outlined latershould be checked to determine thecause. Probable causes are that the driveshaft is binding in the transmission hous-ing (drive tube) sleeve bearings, or thatthe clutch spring is binding on the driveshaft hub.

If the available torque reading is less than20 pounds, follow the procedure fortesting the drag torque.

Drag Torque

Position the washer so the drive pulleycan be accessed, and remove the drivebelt. While holding the transmission tokeep it from turning, manually rotate thedrive pulley counterclockwise until thebrake stays disengaged. Make certainthe drive pulley hub shoulder has rotatedfully against the cams in the spin drivingposition to ensure the complete disen-gagement of the brake. Release thetransmission so it is free to turn.

Place a 1/2 inch socket and torquewrench on the agitator retaining bolt.

Slowly rotate the wrench 360 degrees atapproximately 6 R.P.M. and read thetorque. If the torque reading is over 4inch pounds, remove the brake stator (asdetailed earlier in this section) and re-check the drag torque.

If the torque reading is now under 4 inchpounds, the brake is binding and shouldbe repaired.


NOTE: If the "O" ring is to be reused, beextremely careful not to damage it dur-ing the removal.

Remove the center post, "O" ring andagitator once the drive train is back inplace.

The transmission assembly, when re-moved as described, will have the relatedcomponents assembled to it. Theserelated components should be examinedcarefully before reinstalling.

When installing the transmission, it is necessary that the tub be located on the tub support a certain way if all the

mounting holes are to be properly aligned. This should be done before attempting to mount the tub to the bearing and seal housing.

To assist in correctly positioning the tub, asmall indentation has been formed on thetub support just above one of the tubbrace mounting areas. This is the leftfront tub brace.

When the tub is in proper position andready to be mounted to the tub support,the large tub cover lock (on the side ofthe tub) should be located directly abovethe indentation and tub brace.(See the illustration on page 6-14.)

pinion in a vise using two (2) small blocksof wood to prevent damage to the gearteeth, and repeat the input torque check.

If the torque reading is between 17 and20 inch pounds, the drive shaft is bindingin the sleeve bearings.

If the torque reading still exceeds 20 inchpounds, the clutch assembly is defectiveand must be repaired or replaced.

TRANSMISSION REMOVAL:

The transmission assembly can be re-moved from the washer cabinet afterremoving the drive belt, spin basket,outer tub and the suspension springs.

NOTE: Be sure to dust the base domelightly with cornstarch before installingthe transmission.

IMPORTANT

CAUTION Once the agitator has been removed, the center post slips off the shaft. Therefore, do not attempt to handle the drive train by the center post after the agitator has been removed. In- stead, after removing the agitator and the agitator shaft "O" ring, slip the center post off the shaft and handle the drive train by the shaft.
