4. Inspect direct clutch housing for cracks, worn or damaged clutch lugs, snap ring groove damage or bushing scored or damaged.
5. Inspect clutch backing plate for scoring or heat damage.
6. Inspect composition and steel clutch plates for plate tang damage, delamination, heat damage and wear.
7. Inspect retainer and spring assembly for distortion or collapsed springs and retainer. Check spring guide for damage.
