e. Attach dial indicator on differential case at converter housing
side.
f. Insert SST into differential side gear from transaxle case side.
g. Move SST up and down and measure dial indicator deflection.
h. 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
i. Remove converter housing from transaxle case.
j. Remove final drive assembly from transaxle case.
k. Remove differential side bearing outer race from transaxle case.
l. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from “Parts Information” on
transaxle case.
m. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT-257, "
Components" .
n. 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.Suitable shim thickness = Dial indicator deflection +
Specified bearing preload
