INSPECTION





One-way Clutch 2
1. Inspect for detached rollers, damage, or wear.
2. Install the inner race into the one-way clutch 2, and verify that the one-way clutch 2 turns smoothly and only clockwise. If the one-way clutch 2 turns or locks in both directions, replace the one-way clutch 2. If the one-way clutch 2 turns only counterclockwise, it is installed upside down.





Carrier Hub Assembly
Check for the following and repair or replace as necessary.
1. Damaged or worn gear and operation.
2. Clearance between pinion washers and planetary carrier. Clearance should be 0.2 - 0.7 mm (0.008 - 0.027 inch).
3. Replace the carrier hub assembly if necessary.

ASSEMBLY
1. Assemble in the reverse order of disassembly, referring to the following steps.





2. Install the carrier hub assembly to the inner race.

4. Apply petroleum jelly to the bearing races and the thrust bearing.
5. Install the tabs of the bearing races into the alignment holes on each side of the one-way clutch/carrier hub assembly.
6. Install the thrust bearing to the sun gear drum side of the one-way clutch and carrier hub assembly. Bearing race outer diameter for the sun gear drum side is 72.0 mm (2.83 inch) and the 3-4 clutch side is 57.0 mm (2.24 inch).
