Bearings

Make sure bearings roll freely and are free from noise, cracks,
pitting or wear.

When replacing taper roller bearing, replace outer and inner
race as a set.
ASSEMBLY
1. Attach side gear thrust washers to side gears, then install pinion
mate thrust washers and pinion mate gears in place.
CAUTION:
Apply ATF to any parts.
2. Insert pinion mate shaft.
CAUTION:
When inserting, be careful not to damage pinion mate
thrust washers.
3. Measure the clearance between side gear and differential case
with washers following the procedure below:
a. Set the special tool and dial indicator on side gear.

b. Move side gear up and down to measure dial indicator deflec-
tion. Always measure indicator deflection on both side gears.
c. If not within specification, adjust the clearance by changing the
thickness of differential side gear thrust washers. Refer to AT-
535, "Final Drive" .
4. Install lock pin.
CAUTION:

Do not reuse lock pin.

Make sure that lock pin is flush with case.
5. Press on differential side bearings.
CAUTION:
Apply ATF to differential side bearings.
6. Install differential side bearing outer race and differential side
bearing adjusting shim on transaxle case. Refer to AT- 5 0 8 ,
"Adjustment (1)" .
7. Tighten final gear and tighten fixing bolts to the specified torque
in numerical order shown in the figure after temporarily tighten-
ing them. Refer to AT- 5 0 3 , "
COMPONENTS" . Clearance between side gear and differential case
with washer:
0.1 - 0.2 mm (0.004 - 0.008 in)

1. Install differential side oil seals on transaxle case and converter housing.
CAUTION:

Do not reuse differential side oil seals.

Apply ATF to differential side oil seals.
2. Install parking actuator support to transaxle case. Tighten park-
ing actuator support bolts to the specified torque. Refer to AT-
416, "Components" .
CAUTION:
Pay attention to the direction of parking actuator support.
3. Install parking pawl on transaxle case and fix it with parking
shaft.

DIFFERENTIAL SIDE BEARING PRELOAD
1. Install differential side bearing outer race without differential side
bearing adjusting shim on transaxle case.
CAUTION:
Apply ATF to differential side bearing outer race.
2. Install differential side bearing outer race on converter housing.
CAUTION:
Apply ATF to differential side bearing outer race.
3. Place final drive assembly on transaxle case.
4. Install transaxle case on converter housing. Tighten transaxle
case fixing bolts to the specified torque. Refer to AT- 4 1 6 , "
Com-
ponents" .
5. Attach dial indicator on differential case at converter housing
side.
6. Insert Tool into differential side gear from transaxle case side.
7. Move SST up and down and measure dial indicator deflection.
8. Select proper thickness of differential side bearing adjusting
shim(s). Refer to AT- 5 3 6 , "

9. Remove converter housing from transaxle case.
10. Remove final drive assembly from transaxle case.
11. Remove differential side bearing outer race from transaxle case.
12. Reinstall differential side bearing outer race and differential side
bearing adjusting shim selected from SDS table on transaxle
case. Refer to AT- 5 3 6 , "
DIFFERENTIAL SIDE BEARING PRE-
LOAD ADJUSTING SHIMS" .
13. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT- 4 1 6 , "
Components" .
14. 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.
REDUCTION PINION GEAR BEARING PRELOAD
1. Remove converter housing and final drive assembly from tran-
saxle case.
2. Select proper thickness of reduction pinion gear adjusting shim
using the following procedures.
a. Place reduction pinion gear on transaxle case as shown.
b. Place idler gear bearing on transaxle case.
c. Measure the dimensions “B” “C” and “D” and calculate dimen-
sion “A”.
