` DETERMINING No. 4 THRUST PLATE THICKNESS-INPUT SHAFT END PLAY

Fig. 340:

Fig. 341:

To determine the proper thickness of the No. 4 thrust plate, select the thinnest No. 4 thrust plate. Using petrolatum (Fig. 340) to hold thrust plate in position, install input clutch assembly. Be sure the input clutch assembly is completely seated (Fig. 341).

CAUTION: If view through input speed sensor hole is not as shown above, the input clutches assembly is not seated properly.

Remove the oil pump O-ring (Fig. 342). You will be able to install and remove the oil pump and gasket very easily to select the proper No. 4 thrust plate.

NOTE: Use screw-in dowels or phillips-head screwdrivers to align pump to case.

CAUTION: Be sure to reinstall O-ring on oil pump after selecting the proper No. 4 thrust plate.

Measure the input shaft end play with the transaxle in the vertical position. This will ensure that the measurement will be accurate.

Fig. 343:

Set up and measure endplay using End Play Set 8266 and Dial Indicator Set C3339 as shown in (Fig. 343).

NOTE: Input shaft end play must be 0.005 to 0.025 inch.

For example, if end play reading is.055 inch, select No. 4 Thrust Plate which is 0.071 to 0.074 thick. This should provide an input shaft end play reading of 0.020 inch which is within specifications.

No. 4 Thrust Plate Chart:

See chart to select the proper No. 4 thrust plate.
Reinstall the input clutches assembly with the selected thrust plate.

Install both speed sensors from transaxle case (Fig. 362).

As a final check of the transaxle, measure the input shaft end play. This will indicate when a # 4 thrust plate change is required. The number 4 thrust plate is located behind the overdrive clutch hub. Attach a dial indicator to transaxle bell housing with its plunger seated against end of input shaft (Fig. 363). Move input shaft in and out to obtain end play reading. End play specifications are 0.13 to 0.64 mm (0.005 to 0.025 inch). If not within specifications, make the necessary thrust plate adjustment.
