Illustration 18 g01290833
Attach a suitable lifting device and Tooling (D) to differential (8) .
Install differential (8) . The weight of differential (8) is approximately 182 kg (400 lb).
Install dowel (7) .
Illustration 19 g01001439
Attach differential and bevel gear (1) to Tooling (A) so the ring gear is facing upward.
Install cap (6) and bolts (5) . Tighten bolts (5) to a torque of 370 50 N m (273 37 lb ft).
Install O-ring seal (2) .
Illustration 20 g01291343
Rotate gear (31) . Adjust nut (15) to read zero and back off the nut to the closest lock position on nut (15) .
Rotate nut (11) until a heavy drag is felt. Loosen nut (11) and hand tighten nut (11) .
Illustration 21 g01291391
Install Tooling (G) .Note: Be sure to preload the indicator.
Rotate nut (11) and rotate gear (31) .Note: Preload the bearings by watching the indicator movement. The indicator should move 0.25 0.05 mm (0.009 0.002 inch).
Remove Tooling (G) .
Illustration 22 g01001453
Install Tooling (G) . Check the backlash between gear (31) and pinion (49) . The backlash should be 0.25 + 0.10 mm - 0.07 mm (0.010 + 0.004 inch - 0.003 inch).Note: Make the check at the heel of gear (31) in three places.
Advance and retract nuts (11) and (15) equal amounts. Maintain the bearing preload.
Illustration 23 g01001446
Check the rolling torque at pinion (49) . The rolling torque should be 2.2 .4 N m (20 4 lb in).Note: The rolling torque for a used bearing should be 1.1 .2 N m (10 2 lb in).
Tighten bolts (5) to a torque of 370 50 N m (273 37 lb ft).
The contact pattern between the pinion shaft and bevel gear must be checked. Apply marking compound to three teeth that are adjacent to the bevel gear.
Rotate the pinion shaft for several revolutions in one direction. Rotate the pinion shaft for several revolutions in the opposite direction. Turn the pinion shaft in one direction until the teeth that are marked can be viewed.
Illustration 24 g00101201
The correct area of tooth contact starts near the inside end of the teeth of the bevel gear. The maximum correct area of tooth contact is half the length of the teeth.
Illustration 25 g00101202
If the tooth contact looks like the contact pattern in Illustration 25, proceed to Step 41.
Illustration 26 g00101203
If the tooth contact looks like the contact pattern in Illustration 26, proceed to Step 43.
Remove some of the shims from the pinion housing. Recheck the
