Ring Gear: Adjustments
Fig. 24 Measuring ring gear backlash
1.
Install a dial indicator on the back of the ring gear and measure the amount of runout. Runout should be less than 0.002 inch. If the ring gear
indicates excessive runout, change the position of the assembly with the differential case and measure the runout again. If the runout is still
excessive, replace the ring gear or the differential case as necessary.
2.
Measurement of backlash of the drive pinion against the ring gear should be measured at 4 points on the ring gear with the drive pinion fixed
securely to its final position. Install a dial indicator to the ring gear tooth edges. Backlash should be within specifications.
3.
If the measured backlash is greater than specified, shift shims in an appropriate thickness of the ring gear teeth side to the other side (back of the
ring gear) to obtain the proper backlash.
4.
If the measured backlash is smaller than specified, reverse shifting of shims stated above.
