3. Inspect thrust washer surfaces for signs of
scoring or wear.
4. Inspect bushing for damage. If bushing is dam­
aged, reaction c a r r i e r must be replaced.
5. Inspect reaction c a r r i e r pinions for damage,
rough bearings or excessive t i l t .
6. Check reaction c a r r i e r pinion end play. Should
be .009"-.024" (Fig. 7E-115).
7. Inspect r o l l e r clutch for damaged members.
8. Inspect r o l l e r clutch cage for damage.
9. Inspect front internal gear (output c a r r i e r ) for
damaged teeth.
10. Inspect output c a r r i e r pinions for damage,
rough bearings or excessive t i l t .

2. Using a 1/2" diameter d r i l l , remove stake
marks from end of the pinion pin or pins to be r e ­
placed. This w i l l reduce the probability of cracking
the c a r r i e r when pinion pins are pressed out.
CA UTION: Do not allow drill to remove any stock
from the carrier as this will weaken the part and
future failure would be probable.
3. Using a tapered punch, drive or press pinion
pins out of c a r r i e r (Fig. 7E-117).
4. Remove pinions, thrust washers and r o l l e r
needle bearings.
5. Inspect pinion pocket thrust faces for b u r r s
and remove i f present.
6. Install eighteen (18) needle bearings into each
pinion, using petrolatum to hold bearings i n place.
Use pinion pin as guide (Fig. 7E-118).
