Pinion Depth Adjustment

^ Tools Required:
- J 33838 Pinion Shim Setting Gage
- J 29763 Dial Indicator

1. Pinion depth is adjusted by selecting a shim of the proper thickness.
2. Lubricate the inner and outer pinion bearings liberally with axle lubricant.








3. Hold the pinion bearings in position and install J 33838 and J 29763.
- Set the dial indicator at ZERO, then position it in J 33838. Push the dial indicator downward until the needle rotates approximately 3/4 turns to the right.
4. Tighten the dial indicator in this position.
5. Set the button of J 33838 on the differential bearing bore.
6. Rotate the tool slowly back and forth until the dial Indicator reads the lowest point of the bore. Set the dial indicator to ZERO. Repeat the rocking action of the tool to verify the ZERO setting.
7. After the ZERO setting is obtained and verified, move the tool button out of the differential side bearing bore.
- Record the dial indicator reading.
8. The dial indicator reading is equal to the required shim size.
- Example: If the dial indicator reads 0.84 mm (0.003 inch), a 0.84 mm (0.003 inch) shim is required. Available shim sizes are listed in SPECIFICATIONS.
9. Remove tools and bearing cones.
