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" .

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”.

SELECTING ADJUSTING SHIMS
Measurement points
Gear Ring Bearing Adjusting Shim (Transfer Case Side)
1. Measure the points F, H, I, R and U shown in the measurement points.
2. Convert the values F, H, I, R and U according to the standards below.
3. Check dimension Z on the drive gear side face.
NOTE:
Dimension Z indicates the difference between the optimum engagement and the standard dimensions in
increments of 0.01mm (0.0004 in) written on the drive gear side face.
4. Use the formula below to calculate gear ring bearing adjusting shim (transfer case side) thickness T
1 .
5. Select the gear ring bearing adjusting shim (transfer case side).

For information on selecting an adjusting shim, refer to TF-74, "Gear ring Bearing Adjusting Shim
(Transfer Case Side)" .
CAUTION:

Only one adjusting shim can be selected.

If no adjusting shim with the calculated value is available, select the thicker and closest one.
Gear Ring Bearing Adjusting Shim (Adapter Case Side)
1. Measure the points F, H, J, K, U and V shown in the measurement points.
2. Convert the values F, H, J, K, U and V according to the standards below.
