Take extreme care when removing, and installing bearing
cups and cones. Use only
arbor for installation,
as a hammer may not properly* align the
or cone. Burrs or nicks on the bearing
give a end
play reading while gauging. for proper shims. Impro perly
seated bearing cups and cones are subject to low mi leage’
failure.
Bearing cups and ‘cones should be replaced if they
signs of pitting or heat distress., If distress seen on’
either the cup or bearing rollers, both cone must
be replaced.
Bearing preload and drag torque specifications
maintained to avoid premature’

ADJUSTMENT
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-
bench with C-clamps. Position dial indicator.
(6) Apply a medium load to differential with
and
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
end play and (constant) preload of 0.18 mm
in.).
(8) Remove case bolts. Remove clutch bell housing d ifferen-
tial bearing cup. Install shim(s) selected in step (7). Then
press the bearing cup into clutch bell housing.
(9) Install and torque case bolts to 26 Nm (19
(lO)Using and an inch-pound torque wrench,
check turning torque of the differential assembly c lockwise
and counterclockwise. The turning torque should be 68
to 136 Ncm (6 to 12
If the turning torque is too
high, install a 0.5 mm in.) thinner shim. If the turning
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.
