Build up the clutch disc assemblies properly. Proper clearance between parts is critical to the operation of the unit. Adjust the backlash and thrust block clearance in the following order: 1. The left side gear backlash 2. The right side gear backlash 3. The thrust block clearance Left Side Gear Backlash Adjustment Fig. 292: View Of Left Side Gear Thrust Washer

washers to the pinion shaft opening in the differential case. 4. Install the pinion shaft. It may be necessary to press down on the side gear in order to align the pinion gear shaft opening with the pinion shaft opening in the differential case. If the pinion shaft cannot be installed after pressing on the side gear, replace the locking 5. Install the pinion shaft lock bolt. Tighten: Tighten the pinion shaft lock bolt finger tight. 6. Rotate the pinion gear closest to the lock bolt so that one of the teeth is pointing downward, perpendicular to the ring gear flange. 7. Install a brass drift between the side gear and the pinion shaft. Press the brass drift in far enough in order to compress the clutch discs. NOTE: Refer to Fastener Notice .

Fig. 294: Measuring Backlash Of Differential Pinion Gear & Side Gear 8. Measure the backlash of the pinion gear and the side gear by doing the following: 1. Install the J 7872 (1) to the ring gear flange. See Special Tools. 2. Loosely clamp the J 8001-3 (2) onto the stem on the J 7872 (1). See Special Tools.
