Inspection and Adjustment of Teeth Contact
1. Coat both surfaces of 6-8 teeth of the ring gear
uniformly with a thin coat of red lead.
2. While moving the ring gear back and forth by hand,
rotate the drive pinion several times and check the
tooth contact.
3. If the tooth contact is good, wipe off the red lead.
4. If it is not good, adjust the pinion height, and then
adjust the backlash.

Replace the spacer with a thinner one to move
the drive pinion outward.
