Backlash between Spiral Bevel Pinion and Spiral Bevel Gear
1. Set the dial indicator (lever type) with its finger on the end of
spiral bevel pinion (4).
2. Move the spiral bevel pinion back and forth to each end and
measure the side clearance.
3. If the side clearance exceeds the factory specifications, adjust
with the shims (3) at front end of spiral bevel pinion.
4. Set the dial indicator (lever type) with its finger on the tooth
surface of bevel gear.
5. Measure the backlash by fixing the spiral bevel pinion (4) and
moving bevel gear (2) by hand.
6. If the backlash exceeds the factory specifications, adjust with the
shims (1), (5) at bearing holder (6) and differential case.
7. Adjust the backlash properly by repeating the above procedures.
