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

(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

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

in.).
(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

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)

9. Check that the O-ring is installed on the upper surface
of the valve body at the place shown in the figure.
10. Replace the O-ring of the solenoid valve harnes s grommet
with a new one.
11. Pass the solenoid valve connector through the i nside

REDUCING PRESSURE ADJUSTMENT 23100180033
WHEN SCAN TOOL IS NOT USED 1. Remove parts up to the oil filter in the same wa y as
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
adjust so that the reducing pressure is the standard value.
When the adjustment screw is turned clockwise, the reduc-
ing pressure decreases; when it is turned counterclock-
wise, it increases.
NOTE
When adjusting the reducing pressure, aim for the c enter
value
(60 psi)] of the standard value allowance.
Standard value: 415-435 psi)
Oil pressure change for each turn of adjustment,
screw: 45
(6.5 psi)
3. Install the oil filter and oil
in the same way as for
adjustment of the line pressure.
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
duty, and measure the
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:
(36-44 psi)
Oil pressure change for each turn of adjustment
screw: 22
(3.2 psi)
2. Check to be sure, after completing this adjustme nt, that
the reducing pressure is within the range of
(51-68 psi).
Caution
The adjustment should be made at an oil temperature
of
If the adjustment is made at an oil temperature tha t
is too high, the line pressure will decrease during
idling, with the result that a correct adjustment c annot
be made.
