Fig. 42 Seal Protector
CAUTION: Lube threads and o-ring on adjuster be-
fore installing. Failure to due so will result in thread
damage to the adjuster and differential cover.
(48) Install outer adjuster with new o-ring (Fig.
43). Torque the outer adjuster (special tool 6503) to
the torque reading recorded in step 25. Then seat
bearings by turning differential three or four revolu-
tions in both directions. Tighten adjuster a second
time to same torque recorded in step 25. Again re-
seat bearings. Repeat this sequence until correct ad-
juster torque is maintained.
Fig. 43 Outer Adjuster Installation
(49) To check and/or adjust backlash remove the
inspection plug from the top of the differential and
install dial indicator as shown in figure 44. The tip of
the dial indicator must be perpendicular against one of
the ring gear teeth. Hold transfer shaft with locking
pliers. Move ring gear back and forth with special tool
6548. Read the amount of backlash with dial indicator.
Backlash should be 0.006 to 0.009 thousands of an
inch.

If there is too much backlash, loosen the outer
adjuster with special tool 6503. Then turn the inner
adjuster so that it moves away from the ring gear.
After adjusting the inner adjuster, retighten the outer
adjuster to the torque recorded in step 25. The inner
adjuster should be turned in small increments.
If there is not enough backlash, loosen the outer
adjuster with special tool 6503. Then turn the inner
adjuster so that it moves towards the ring gear.
After adjusting the inner adjuster, retighten the outer
adjuster to the torque recorded in step 25. The inner
adjuster should be turned in small increments.
