Where are the shims on a ring and pinion?
Where are the shims on a ring and pinion?
Pinion depth is controlled by shims. Shims may be located between the Inner pinion bearing & pinion head or they may be between the inner Pinion bearing cone and carrier housing. In either case removing a shim will Move the pinion away from the center line of the ring gear while adding a shim will move it toward the centerline 1.
When to add shims to a ring gear?
If the wit- ness pattern shows heavy on the “toe” (inboard area of the ring gear), sub- tract shims. If the pattern is heavy on the “heel” (outboard area of the ring gear teeth), add shims. Ideally, the contact pattern should be seen in the middle area of the teeth. Resetting the pinion depth may be necessary as well.
What do you need to know about ring and pinion installation?
During the ring & pinion installation, there are four pr imary adjustments that will need to be made. 1. Pinion Depth ± The distance from the face of the pinion gear to the centerline of the ring gear. This is adjusted by adding or subtracting shims to the inner pinion bearing.
How is the depth of the pinion gear adjusted?
The pinion gear depth is adjusted using shims placed in the housing. This adjustment determines the mesh of the pinion into the ring gear. Adding shims will increase the depth of the pinion shaft, and removing shims will decrease the depth.

Where does the drive pinion Shim need to be?
The differential ring gear backlash is correct, a thinner drive pinion shim is needed. A decrease will move the drive pinion toward the differential ring gear. A high, thin contact pattern that is worn toward the toe.
