1. Before the bevel gear group is installed in the carrier, tighten nut (14) on pinion shaft (11) finger tight, and check for the torque needed to turn the pinion shaft (any resistance to turning will be caused by seal (1) on the pinion shaft). Make a record of the torque.2. Tighten nut (14) on pinion shaft (11) until the torque needed to turn the pinion shaft is 0.7 to 0.5 N m (6.00 to 4.00 lb in) more than the torque found in Step 1.3. Install the bevel gear group in the carrier and tighten bolts.4. Put the carrier in a position so the centerline for the axle is vertical and bevel gear (13) is on the bottom.5. Make an adjustment to nut (12) until free movement (backlash) between bevel gear (13) and pinion shaft (11) is ... 0.25 0.05 mm (.010 .002 in) Make adjustments to nut (12) to remove end play while the adjustment is made to nut (15).6. Tighten nut (15) to be sure the bearings and cages are against their seats. Loosen nut (15), then finger tighten the nut to remove end play.7. Install the locks.8. Tighten the bolts.9. Turn the bevel gear in the carrier and check the free movement (backlash) again between the bevel gear (13) and the pinion shaft (11).Adjustment Procedure For Backlash Of Ring Gear And Preload Of Differential Support Bearings Through The Side Bores In The Differential Case
1. Disconnect the parking brake actuator by releasing it with air pressure and removing the cotter pin and pin or use air to keep the brake disengaged while adjustments are being
