Backlash between Spiral Bevel Pinion Shaft and Spiral Bevel
Gear
1. Place the solder wire (2) on the gear tooth of the spiral bevel
gear (1).
2. Install the spiral bevel gear (1) and the differential yoke shaft (3)
into the front axle case.
3. Install the spiral bevel pinion shaft (4) to the front axle case.
Install the internal cir-clip to the front axle case.
4. Turn the spiral bevel pinion shaft (4) holding the differential yoke
shaft (3) by hand lightly.
5. Remove the solder wire (2). And measure the solder wire (2).
6. If the backlash is not within the factory specifications, change
the adjusting collars (5), (6). For example change the adjusting
collar (6) to 0.1 mm (0.004 in.) smaller size, and change the
adjusting collar (5) to 0.1 mm (0.004 in.) larger size.
7. Adjust the backlash properly by repeating the above
procedures.

(Reference)
• Above factory specification should be measured on the tooth of
spiral bevel pinion. When measuring the backlash on the spline
of its shaft, factory specification will be 0.0571 to 0.1714 mm
(0.00225 to 0.00675 in.).
• Thickness of adjusting collars (5), (6):
3.4 mm (0.134 in.)
3.6 mm (0.142 in.)
3.8 mm (0.150 in.)
4.0 mm (0.157 in.)
4.1 mm (0.161 in.)
4.2 mm (0.165 in.)
4.4 mm (0.173 in.)
4.6 mm (0.181 in.)
