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.

torque case bolts to 29 Nm (21
(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.

8. Turn the adjustment screw of the regulator valve and
adjust so that the line pressure (kickdown brake pressure)
becomes the standard value.
When the adjustment screw is turned clockwise, the line
pressure decreases; when it is turned to counterclockwise,
it increases.
Standard value: psi)

for adjustment of the line pressure. The valve body need
not be removed.
2.Tune the adjustment screw of the lower valve body a nd

When the adjustment screw is turned clockwise, the reduc-
ing pressure decreases; when it is turned counterclock-
wise, it increases.

4. Perform the oil pressure test. Readjust if neces sary.
WHEN SCAN TOOL IS USED 1. Use the scan tool to force-actuate the pressure control
solenoid valve to 50

brake apply pressure at that time. If the brake
apply pressure is not within the standard value, ad just
using the reducing pressure adjustment screw.
Standard value:
