Gears
1.
Check gear teeth for frosting and pitting. Frosting of gear teeth
faces presents no threat of transmission failure. Often in continued
operation of the unit, frosted gears “heal” and do not progress to
the pitting stage. In most cases, gears with light to moderate pitted
teeth have considerable gear life remaining and can be reused, but
gears in the advanced stage of pitting should be replaced.
2.
Check for gears with clutching teeth abnormally worn, tapered, or
reduced in length from clashing during shifting. Replace gears
found in any of these conditions.
3.
Check axial clearance of gears.
