5. Attach dial indicator on differential case at converter housing
side.
6. Insert SST into differential side gear from transaxle case side.
7. Move SST up and down and measure dial indicator deflection.
8. Select proper thickness of differential side bearing adjusting
shim. Refer to “Parts Information” for differential side bearing
adjusting shim selection.
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload
9. Remove converter housing from transaxle case.
10. Remove final drive assembly from transaxle case.
11. Remove differential side bearing outer race from transaxle case.
12. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from “Parts Information” on
transaxle case.
13. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT- 2 4 6 , "
Components" .
14. Insert SST and measure turning torque of final drive assembly.
Turn final drive assembly in both directions several times
to seat bearing rollers correctly.
When old bearing is used again, turning torque will be
slightly less than the above.
Make sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Remove converter housing and final drive assembly from tran-
saxle case.
2. Select proper thickness of reduction pinion gear bearing adjust-
ing shim using the following procedures.

CAUTION:
Lock idler gear with parking pawl when tightening lock nut.
8. Measure turning torque of reduction pinion gear.
When measuring turning torque, turn reduction pinion
gear in both directions several times to seat bearing roll-
ers correctly.
If turning torque is out of specification, decrease or
increase thickness of reduction pinion gear adjusting
shim.
