Conventional Differential (Gear Assembly)

Fig. 9 Installing side & pinion gears:

1. Install the thrust spacers in the original positions behind the side gears, then assemble the pinions and side gears, right and left, in the differential gears.
2. With pinion washers attached to the pinion gears, insert both pinion gears at the same time into mesh with the side gears by rotating the pinions.
3. Insert the drive pinion shaft.

Fig. 10 Checking side & pinion gear backlash:

4. Check the pinion and side gear backlash. If the backlash is out of limits, adjust by selecting a side gear thrust spacer of proper size. In this case, the backlash, right and left, should be adjusted to an equal value.
5. With the drive pinion shaft aligned with the drive pinion shaft lock pin hole in the differential case, drive the lock pin into the hole from the back side of the ring gear. Securely stake the lock pin at two places with a punch to prevent its dislocation.
6. Clean all the foreign substances completely from the ring gear mounting surface of the differential case. Place the ring gear in proper position on the case. On A type units, install bolts with lock washers. Temporarily tighten each bolt evenly, then torque to 47-54 ft. lbs., in a crossing pattern. Secure bolts by bending lock washers. For B type units, apply Loctite No. 271 or equivalent anaerobic adhesive to ring gear bolts and threaded holes. Tighten in same manner as above and torque to 58-65 ft. lbs. Do not move vehicle for one hour to allow anaerobic adhesive to harden. The lock washers should be replaced with new parts whenever they have been removed. They should be securely bent to the shape of differential case.
