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.
