ADJUSTMENT - CONTINUED

Rotate differential assembly and ring gear (13) and read dial indicator. If runout of ring gear (13) exceeds 0.008 in. (2.03

mm), remove differential assembly and ring gear (13) and inspect differential assembly for problem. Replace defective

parts and reinstall differential assembly and ring gear (13) into differential carrier (8). Repeat preload adjustment of dif-

ferential bearings.

To adjust backlash of ring gear (13), attach a dial indi-

cator to the mounting flange on differential carrier (2).

10.

Adjust dial indicator so that plunger is against the

tooth surface on ring gear (13).

11.

Adjust dial of indicator to zero.

12.

Hold bevel pinion in position.

13.

Read dial indicator while rotating ring gear (13) a

small amount in both directions.

14.

Adjust backlash of old gear set to setting measured

before carrier was disassembled, 0.008 to 0.018 in.

(2.032 to 0.457 mm).

409-1255

15.

If new gear set is installed, adjust backlash to 0.012 in. (0.304 mm).

NOTE

When adjusting backlash, adjust only the ring gear; do not adjust the bevel pinion.

16.

Increase backlash by loosening bearing adjusting ring (4) opposite teeth of ring gear (13), and tightening bearing adjust-

ing ring (4) on ring gear (13) side of differential assembly. Make adjustments one notch at a time until backlash is within

specifications.

17.

Decrease backlash by tightening bearing adjusting ring (4) opposite teeth of ring gear (13), and loosening bearing

adjusting ring (4) on ring gear (13) side of differential assembly. Make adjustments one notch at a time until backlash is

within specifications.
