measure the oil pump housing-to-rotor clear-
ance.

D: ASSEMBLY
1) Measure the dimension “A” of the drive pinion
shaft.

2) Using a press, press–fit the new roller bearing
into the specified position.
NOTE:
If excessive force is applied to roller bearing, the
roller bearing will not turn easily.
3) After fitting a new O-ring to the shaft, attach the
drive pinion collar to the shaft.
4) Tighten the new lock nuts using ST1, ST2 and
ST3.
Using the following equation, calculate the tighten-
ing torque.
T2 = L2/(L1 + L2) × T1
T1: 116 N·m (11.8 kgf-m, 85.3 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST2 length 0.072 m (2.83 in)
L2: Torque wrench length

ST3 499787500 ADAPTER
NOTE:
Attach ST2 to torque wrench as straight as possi-
ble.
5) Measure the starting torque of the bearing. Make
sure the starting torque is within the specified
range. If the torque is not within specified range, re-
place the roller bearing.
Starting torque:
7.6 — 38.1 N (0.776 — 3.88 kgf, 1.7 — 8.6 lb)

4) Adjust the drive pinion and hypoid driven gear
backlash. Differential Assembly.>
5) Apply red lead evenly to the surfaces of three or
four teeth on hypoid driven gear. Rotate the drive
pinion in the leftward and rightward for several
times. Remove the oil pump cover, and check the
tooth contact pattern.
If the teeth contact is inappropriate, adjust the
backlash or thickness of the shim. ADJUSTMENT, Front Differential Assembly.>
•Correct tooth contact
Check item: Tooth contact surface is slightly
shifted toward the toe side under a no-load con-
dition. (When driving, it moves towards the heel
side.)
