>> D << Drive Pinion Rotation Torque Adjustment/Oil Seal Press-Fitting

Adjust the drive pinion rotation torque in the following steps:

1. Insert the drive pinion into the gear carrier. From rear side of the carrier, assemble the drive pinion spacer, drive pinion front shim and drive pinion front bearing inner race.
   NOTE: Do not assemble the oil seal.
2. Use the following special tools to tighten the differential nut to the specified torque:
   • Locking nut wrench (MB992112)
   • Drive pinion holder (MB992113)
3. Rotate the drive pinion several turns, and then measure the drive pinion rotation torque.
   STANDARD VALUE SPECIFICATION
   
   

   Bearing type	Bearing lubrication	Rotation torque N.m (in-lb)
   New	None (coated with rust inhibitor oil)	0.7 - 1.2 (7 - 10)

4. When the rotation torque is not within the standard value range, adjust the torque by selecting the drive pinion front shim(s).
   NOTE: When selecting the drive pinion front shim(s), select the drive pinion spacer to minimize the number of the shims to be used. There are two drive pinion spacers available:

   Drive pinion spacer height A mm (inch)
   24.3 (0.96)
   23.6 (0.93)

5. Use the following special tools to tighten the differential nut to the specified torque:
   • Locking nut wrench (MB992112)
   • Drive pinion holder (MB992113)

     Tightening torque: 190 ± 3 N.m (140 ± 22 ft-lb)

6. Use special tool bushing remover and installer base (MB991180) to press-fit the oil seal.
7. Rotate the drive pinion several turns, and then measure the drive pinion rotation torque.

   STANDARD VALUE SPECIFICATION
   
   

   Bearing type	Companion flange lubrication	Rotation torque N.m (in-lb)
   New	None (coated with rust inhibitor oil)	0.7 - 1.2 (7 - 10)

8. When the rotation torque is not within the standard value, check the differential locking nut tightening torque or the oil seal assembly condition.
