Tools Required

1. Inspect the reverse clutch housing (500) for the following:

•	Plugged feed holes

•	Snap ring for overexpansion

•	Outer surface for scoring or burning

•	Reverse clutch housing checkball for damage, the checkball should move freely in the capsule.





Important: Some models will have a reverse clutch pack consisting of a belleville plate (514), three steel plates (511), three fiber clutch plate assemblies (513) and a backing plate (512) with identification marks of A, B or C.

Some models will have a reverse clutch pack consisting of a waved plate (514), two steel plates (511), two fiber clutch plate assemblies (513) and a backing plate (512) with identification marks of 1, 2 or 3.
2. Inspect the reverse clutch steel plates (511), the backing plate (512) and the belleville plate (514) for scoring or burning.
3. Inspect the snap ring (510) for overexpansion.
4. Replace all of the fiber clutch plate assemblies (513).



5. Inspect the reverse clutch piston inner seal (506) and outer seal (507) for damage.
6. Inspect the checkball orifices on the reverse clutch piston assembly (505) for damage caused by peening. The checkball should move freely in the piston capsule.



7. Inspect the reverse clutch housing bushings (502, 503) for damage.



8. Inspect the spring and retainer assembly (508) for damaged or missing springs.



9. Inspect the second sprag (517) for flipped or damaged sprags. Inspect both of the second sprag races for damage.



10. Install new seals (506, 507) on the reverse piston (505).



11. Install the reverse clutch piston (505) into the reverse clutch housing. Install the J 39054 in order to protect the inner seal. Make sure that the outer seal does not roll backwards. Apply a light coating of Transjel™ so that the seal will slide easily.



12. Install the spring and retainer assembly (508, 509) into the reverse clutch housing (500).



13. Use the J 39694 spring compressor to compress the spring and install the snap ring (510). Remove the compressor tool.
