PREINSPECTION
While holding the one-way clutch outer race, verify that the one-way clutch inner race rotates smoothly when turned counterclockwise and locks when turned clockwise. If not as specified, replace the one-way clutch 1.





DISASSEMBLY
Disassemble in the order shown in the illustration.





INSPECTION
1. Measure the small sun gear and sun gear drum inner diameters. Inner diameter of the small sun gear is 24.0 mm (0.945 inch) maximum and the sun gear drum is 33.4 mm (1.31 inch) maximum.
2. If not within the specification, replace the small sun gear or sun gear drum.

ASSEMBLY
- Assemble in the reverse order of disassembly, referring to the following steps:
1. Install the small sun gear into the sun gear drum.





2. Install a new snap ring.





3. Apply petroleum jelly to the thrust bearing and secure it to the one-way clutch inner race. Thrust bearing outer diameter is 62.5 mm (2.46 inch).





4. Verify that the spring cage of the one-way clutch faces toward the outer race as shown.
5. Apply petroleum jelly to the thrust bearing and secure it to the one-way clutch 1. Thrust bearing outer diameter is 62.5 mm (2.46 inch).
6. Apply ATF to the one-way clutch and one-way clutch outer race.
7. Install the one-way clutch inner race into the one-way clutch outer race by turning the inner race counterclockwise. If the one-way clutch inner race turns or locks in both directions, replace the one-way clutch 1.
8. Apply ATF to the one-way clutch inner race.





9. Hold the one-way clutch outer race. Verify that the inner race rotates smoothly in the counterclockwise direction only. If the one-way clutch inner race turns only clockwise, the spring cage could be installed upside down.





10. Align the splines of the one-way clutch inner race with the splines on the small sun gear hub as shown in the figure.





11. Install a new snap ring.





12. Verify that when the small sun gear is held, the one-way clutch outer race turns smoothly and only clockwise.
