1. Set the dial indicator (lever type) with its finger on the tooth surface.
2. Measure the backlash by fixing the 8T spiral bevel pinion and moving the bevel gear by hand.
3. If the backlash exceeds the factory specification, decrease the number of shims at right bearing case (right) and insert the removed shims to the left bearing case (left).
If the backlash is less than the factory specification, decrease the number of shims at left bearing case (left) and insert the removed shims to the right bearing case (right).
4. Adjust the backlash properly by repeating the above procedures.
5. Apply red lead lightly over several teeth at three positions equally spaced on the bevel gear.
6. Turn the 8T spiral bevel pinion while pressing a wooden piece against the periphery of the bevel gear.
7. Check the tooth contact. If not proper, adjust according to the instructions below.
