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.

Backlash between Spiral Bevel Pinion Shaft and Spiral Bevel
Gear
1. Set a dial gauge (lever type) with its finger on the spline of spiral
bevel pinion shaft.
2. Measure the backlash by moving the spiral bevel pinion shaft by
hand lightly.
3. If the backlash is not within the factory specifications, change the
adjusting collar (3), (4).
For example, when the backlash is too large, change the collar
(3) to thinner one and change the collar (4) to thicker one. At this
time, if the collar (3) is thinned by 1 mm, the collar (4) must be
thickened by 1 mm.
(Reference)
• Standard size of adjusting collar (3), (4) :
6.0 mm (0.236 in.) of thickness (total 12.0 mm)
• Standard size of adjusting shim (5) :
2.0 mm (0.079 in.) of thickness
4. Adjust the backlash properly by repeating the above procedures.
