6. Zero the dial indicator; then while holding the pinion
stationary, rock the ring gear assembly forward and
back and record the backlash. Backlash must be
0.011-0.015 in. If backlash is within specifications,
proceed to Ring Gear End-Play. If backlash is not
within specifications, increase shim thickness to
increase backlash or decrease shim thickness to
decrease backlash.

NOTE: Higher backlash settings usually result in
quieter gear operation.
Ring Gear End-Play
After correcting backlash, ring gear end-play can be
adjusted. To adjust end-play, use the following proce-
dure.
1. Secure the gear case in a holding fixture with the
cover side up; then install a dial indicator contacting
the ring gear axle flange.

2. Zero the dial indicator; then push the ring gear
toward the dial indicator and release. End-play
should be 0.004-0.008 in.
3. To increase end-play, decrease the shim thickness.
To decrease end-play, increase the shim thickness.

NOTE: Once proper backlash and end play are
established, the gear case can be assembled.
