4. In order to get bearing preload, subtract 0.05 mm (.002 in.) from the shim pack thickness found in Step 3. This is the shim pack thickness that needs to be installed. Power Transfer Group Bearing and Gear Clearance (Backlash) Adjustments 5. Install the correct thickness of shims (1), bearing cone (2), the washer, lockwasher, and nut (3). Tighten nut (3) to a torque of 180 L 25 NҐm (135 L 18 lbҐft). Tools Needed: Dial Indicator Group (A) 4 1 3 2 Rolling Torque Check 9 8 7 5 6. Check the rolling torque of the pinion as shown. It must be 0.85 to 1.70 NҐm (7.5 to 15.0 lbҐin). If the torque is not correct, add or remove shims (1) until it is correct.
Removal of shims (1) increases the rolling torque. Adding shims (1) decreases the rolling torque. Record the actual rolling torque after the shims have been added or removed. Backlash Adjustment (1) Bearing Cone. (2) Bevel Gear. (3) Bolt. (4) Bearing Cup. (5) Bearing Cap. (7) Lockwasher. (8) Locknut. (9) Pinion Gear. 1. Install bearing cones (1) on the differential case. 2. Put bevel gear (2) on the differential case and tighten ten bolts (3) to a torque of 70 L 15 NҐm (50 L 11 lbҐft). Put bearing cups (4) on bearing cones (1). Power Train Testing And Adjusting 25
