GEAR CASE
The sealant used to seal the transaxle case halves is Loctite
51817 or equivalent. The sealant used for the bearing end
plate cover is Loctite
or equivalent.
The components that are left in the gear cases when the
gear train is pulled out are the:
Axle shaft seals
Output bearing race and retainer Input bearing and sleeve
Differential bearing cones
Shifter rail bushings ,
Shifter shafts
Shifter shaft seals

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

(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

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

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.
