^ Tools Required:
- J 34943 Pinion Pilot Bearing Installer
- J 8092 Driver Handle

INSTALL OR CONNECT

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.





1. Pinion pilot bearing using J 34943 and J 8092.
A. Bolt the guide plate to the axle housing.
B. Place the bearing onto the guide.
C. Drive the bearing into the housing. The part number of the bearing must face the pinion flange.
2. Measure the pinion bearing shims. If a new ring and pinion is installed, the pinion bearing shim pack must be adjusted.
- Pinion service shims are available in sizes from 0.152 to 0.6096 mm (0.006 to 0.024 inch).
- If the original pinion is being reused, the original pinion shims should also be reused.
3. Pinion bearing shims to the pinion cage.
