Bearings

Make sure bearings roll freely and are free from noise, cracks,
pitting or wear. Replace if necessary.
CAUTION:
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
gear thrust washers.

Apply ATF to pinion mate shaft.
3. Measure clearance between side gear and differential case with
washers following the procedure below:
a. Set SST 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 clearance by changing thick-
ness of differential side gear thrust washers. Refer to “Parts
Information” for side gear thrust washers selection.
4. Install lock pin with pin punch.
CAUTION:

Do not reuse lock pin.

Make sure that lock pin is flush with differential 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- 3 4 0 ,
"Adjustment (1)" .
7. Tighten final gear and tighten fixing bolts to the specified torque
in numerical order as shown in the figure after temporarily tight-
ening them. Refer to AT- 3 3 5 , "
COMPONENTS" . Clearance between side gear and differential
case with washer:

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.

Drive differential side oil seals into case until it became flush.
Refer to dimensions “A”, “B”.
Unit: mm (in)
NOTE:
Differential side oil seal pulling direction is used as the refer-
ence.
2. Install parking actuator support to transaxle case. Tighten park-
ing actuator support bolts to the specified torque. Refer to AT-
246, "Components" .
CAUTION:
Be careful to direction of parking actuator support.

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.

5. Attach dial indicator on differential case at converter housing
side.
6. Insert SST 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. Refer to “Parts Information” for differential side bearing
adjusting shim selection.
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload
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 “Parts Information” on
transaxle case.
13. Reinstall converter housing on transaxle case and tighten con-
verter housing mounting bolts to the specified torque. Refer to
AT- 2 4 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 bearing adjust-
ing shim using the following procedures.
a. Place reduction pinion gear on transaxle case as shown.Suitable shim thickness = Dial indicator deflection +
Specified bearing preload
