TURBO HYDRA-MATIC TRANSMISSION 7E-43
INSPECTION OF REACTION CARRIER, ROLLER
CLUTCH AND OUTPUT CARRIER ASSEMBLY
1
B
Inspect band surface on reaction carrier for
signs of burning or scoring.
2. Inspect roller clutch outer race for scoring or
wear.
3. Inspect thrust washer surfaces for signs of
scoring or wear.
4. Inspect bushing for damage. If bushing is dam-
aged, reaction carrier must be replaced.
5. Inspect reaction carrier pinions for damage,
rough bearings or excessive tilt.
6. Check reaction carrier pinion end play. Should
be .009"-.024" (Fig. 7E-115).
7. Inspect roller clutch for damaged members.
8. Inspect roller clutch cage for damage.
9. Inspect front internal gear (output carrier) for
damaged teeth.
10. Inspect output carrier pinions for damage,
rough bearings or excessive tilt.
11. Check output carrier pinion end play. Should
be .009"-.024" (Fig. 7E-116).
12. Inspect parking pawl lugs for cracks or
damage.
13. Inspect output locating splines for damage.
14. Inspect front Internal gear ring for flaking.
PINION REPLACEMENT PROCEDURE
(Reaction Carrier Shown)
1. Support carrier assembly on its front face.

Fig. 7E-116 Checking Output Carrier Pinion End Play
2. Using a 1/2" diameter drill, remove stake
marks from end of the pinion pin or pins to be re-
placed. This will reduce the probability of cracking
the carrier 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 carrier (Fig. 7E-117).
4. Remove pinions, thrust washers and roller
needle bearings.
5. Inspect pinion pocket thrust faces for burrs
and remove if present.
6. Install eighteen (18) needle bearings into each
pinion, using petrolatum to hold bearings in place.
Use pinion pin as guide (Fig. 7E-118).
