Backlash between Differential Pinion and Differential Side
Gear

1. Set a dial gauge (lever type) on a tooth of the differential pinion.

2. Fix the differential side gear and move the differential pinion to

measure the backlash.

3. If the measurement exceeds the factory specifications, adjust

with the differential side gears shims.

(Reference)

• Thickness of adjusting shims

0.4 mm (0.016 in.)

0.6 mm (0.024 in.)

0.8 mm (0.031 in.)

1.0 mm (0.039 in.)

1.2 mm (0.047 in.)

• Tooth contact: More than 35 %

Turning Torque of Spiral Bevel Pinion Shaft (Pinion Shaft Only)

1. Install the spiral bevel pinion shaft assembly only to the front

axle case.

2. Measure the turning torque of spiral bevel pinion shaft.

3. If  the  turning  torque  is  not  within  the  factory  specifications,

adjust with the lock nut.

If the turning torque is not able to adjust by lock nut (2), change

the thickness of collar (1) and adjust with lock nut (2) again.

(Reference)

• Standard size of collar (1): 10.0 mm (0.394 in.) of thickness

NOTE

• After turning torque adjustment, be sure to stake the lock

nut.
