Pinion Bearing Preload

NOTE: The pinion gear depth must be set before the preload. Refer to
1. Install the pinion gear, spacer, and shims into the housing.
2. Install the outer pinion bearing.
3. Install the main gear onto the pinion shaft and torque the pinion nut to 154-169 ft lbs.
4. Measure the torque required to rotate the pinion shaft in the housing.
5. The torque required to rotate the pinion shaft should be between 1.1 and 2.9 ft-lbs. If the
torque is not within specifications then add or subtract from the total shim thickness and
repeat this procedure until the proper preload is obtained.
NOTE: Add shims to decrease torque.
