True bearing turning torque readings can only be obtained
with the gear train removed from the case.
(1) Remove bearing cup and existing shim from clutc h
housing case.
(2) Press in new bearing cup into bell housing case (or use
a cup that has been ground down on the outer edge
for ease of measurement).
(3) Press in new bearing cup into gear case side.
(4) Lubricate differential bearings with SAE
engine
oil. Install differential assembly in transaxle gear case.
Install clutch bell housing over gear case.

(5) Position transaxle with bell housing facing dow n on work-

(6) Apply a medium load to differential with

a T-Handle, in the downward direction. Roll differe ntial
assembly back and forth many times. This will settl e the
bearings. Zero dial indicator. To obtain end play r eadings,
apply a medium load in the upward direction while r olling
differential assembly back and forth. Record end play.
(7) The shim required for proper bearing preload is total of

(8) Remove case bolts. Remove clutch bell housing d ifferen-

press the bearing cup into clutch bell housing.
(9) Install and torque case bolts to 26 Nm (19

torque is too low, install a 0.5 mm in.) thicker shim.
(11) Recheck turning torque. Repeat Step (10) until the proper
turning torque is obtained.
