9) Calculate the following equation, then select one
or two pieces of drive pinion shim from the table be-
low.

— A)]
NOTE:
A: Measured value from step 1).
B: Measured value from step 8).

10) Apply gear oil to the side face of taper roller
bearing, then install the drive pinion shaft and se-
lected shim to adapter plate.
Tightening torque:

E: INSPECTION
1) Using the spring balancer, measure the starting
torque. If the starting torque is out of specification,
replace the taper roller bearing.
Starting torque:
0 — 0.95 N (0 — 0.097 kgf, 0 — 0.21 lb)
2) Gears
Replace the gears in the following case.
• Gear teeth surfaces are broken or excessively
worn.
3) Bearings
Replace the bearings in the following cases.
• Worn, rusted and damaged bearing
• Bearings that fail to turn smoothly or make ab-
normal noise when turned
4) Adapter plate
Replace the adapter plate in the following cases.
• Worn, rusted and damaged bearing
• Damaged adapter plate
5) Make sure the pipe and pipe chamber is not
damaged or clogged. Repair or replace if damaged
or clogged.
F: ADJUSTMENT
1) Inspect and adjust the backlash between hypoid
driven gear and drive pinion. <Ref. to 6MT-108,
HYPOID GEAR BACKLASH, ADJUSTMENT,
Front Differential Assembly.>
2) Apply a uniform thin coat of red lead on both
teeth surfaces of three or four teeth of the hypoid
driven gear.
3) Install the drive pinion shaft assembly to clutch
housing, then tighten at least four bolts.
