Backlash between Bevel Pinion Shaft and Bevel Gear
1. Set a dial gauge (lever type) with its finger on the spline of bevel
pinion shaft.
2. Measure the backlash by moving the bevel pinion shaft by hand
lightly.
3. If the backlash is not within the factory specifications, change the
adjusting collars (3), (4). For example, change the adjusting
collar (4) to 0.1 mm (0.0039 in.) smaller size, and change the
adjusting collar (3) to 0.1 mm (0.0039 in.) larger size.
4. Adjust the backlash properly by repeating the above procedures.

(Reference)
• Above factory specification should be measured on the tooth of
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 (3), (4) :
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.)

Backlash between 12T Bevel Gear and 12T Bevel Gear
1. Place three trips of fuse wire around the 12T bevel gear (1) with
grease.
2. Fix the rear axle case, bevel gear case and front gear case.
3. Turn the axle.
4. Remove the bevel gear case from rear axle case, and measure
the thickness of the fuse wires with an outside micrometer.
5. If the backlash is not within the factory specifications, adjust with
shim (3).
