Assembly (1)UCS005WG
1. Drive each differential side oil seal evenly using a drift (SST and
commercial service tool) so that differential side oil seal pro-
trudes by the dimension “C” or “D” respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)
NOTE:
Differential side oil seal pulling direction is used as the reference.
Drift to be used:
2. Install O-ring on governor cap.
CAUTION:

Do not reuse O-ring.

Apply ATF to O-ring.
3. Install governor cap in transaxle case.
4. Install snap ring in transaxle case.
5. Install parking actuator support (1) on transaxle case.
(A): Inside
(B): Outside
CAUTION:
Be careful with the direction of parking actuator support (1).
6. Tighten parking actuator support fitting bolts to the specified
torque. Refer to AT-257, "
Components" .
7. Install parking pawl (2) on transaxle case, and fix it with parking
shaft (1).
Dimension “C” 0 ± 0.5 (0 ± 0.020)

DIFFERENTIAL SIDE BEARING PRELOAD
1. Select proper thickness of differential side bearing adjusting shim using the following procedures.
a. Install differential side bearing outer race without differential side
bearing adjusting shim on transaxle case.
CAUTION:
Apply ATF to differential side bearing outer race.
b. Install differential side bearing outer race on converter housing.
CAUTION:
Apply ATF to differential side bearing outer race.
c. Place final drive assembly on transaxle case.
d. Tighten converter housing fitting bolts (1) and (2) to the specified
torque. Refer to AT-349, "

e. Attach dial indicator on differential case at converter housing
side.
f. Insert SST into differential side gear from transaxle case side.
g. Move SST up and down and measure dial indicator deflection.
h. Select proper thickness of differential side bearing adjusting
shim. Refer to “Parts Information” for differential side bearing
adjusting shim selection.
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload
i. Remove converter housing from transaxle case.
j. Remove final drive assembly from transaxle case.
k. Remove differential side bearing outer race from transaxle case.
l. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from “Parts Information” on
transaxle case.
m. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT-257, "
Components" .
n. Insert SST and measure turning torque of final drive assembly.

Turn final drive assembly in both directions several times
to seat bearing rollers correctly.

When old bearing is used again, turning torque will be
slightly less than the above.

Make sure torque is close to the specified range.Suitable shim thickness = Dial indicator deflection +
Specified bearing preload
Bearing preload: Refer to AT- 3 8 2 , "
Final Drive" .
