Planetary Gear and Output Shaft Inspection

Reassemble components by reversing disassembly procedure and noting the following points.

- Refer to Components Planetary Gear and Output Shaft Components
when installing each component.
- When installing new seal ring, use new one.
- Install planetary sun gear as shown in figure.

NOTE:
A is longer than B.





- Fit retaining rings into groove securely.
- Install one-way clutch as shown in figure.











- Install reverse brake reaction plate (2) to front planetary gear (1).
With reverse brake reaction plate (2) fixed stationary, turn front planetary gear (1) clockwise to check that it locks and then counterclockwise to check that it turns smoothly.
