Ring and Pinion Gears

NOTE: Ring and pinion gears are matched sets and both are replaced any time a replacement of either is necessary.

Inspect
- Ring and pinion gear teeth for cracking, chipping, scoring, or excessive wear.
- Pinion gear splines for wear.
- Pinion flange splines for wear. The fit of the pinion gear splines on the pinion flange.
- The sealing surface of the pinion flange for nicks, burrs, or rough tool marks that could cause damage to the seal's inside diameter and result in an oil leak.
- All worn or broken parts and replace if necessary.

Important: A new pinion flange must also be replaced when ring and pinion gears are replaced to maintain proper system balance.
