POWER TRAIN TM 5-3805-263-14&P-2 5. 6. 7. 8. 9. 10. 11. 12. 13. DISASSEMBLY AND ASSEMBLY DIFFERENTIAL Heat bearing (4) in oil to a temperature of 275^oF (135^oC). Install bearing (4) on pinion (1). Make sure the bearing is in its seat in the bearing cup. Lift the carrier and remove the block from under the pinion. Put the carrier on the floor. Remove tooling (A) from the carrier. Install the washer, the lock and nut (5) on the pinion. Do not tighten the nut. Put two .250 in. (6.35 mm) dowels in the splines of the pinion. Put the dowels in position 180^o apart. Install tooling (B) over the pinion and the dowels. Check the amount of torque needed to move the pinion without any preload on the pinion bearings. Remove the torque wrench from tooling (B). Install a ratchet on tooling (B). Install tool (C) on nut (5). Tighten nut (5) with tool (C) while holding the pinion with the ratchet. Tighten the nut enough to get a torque of 6 ± 4 lb. in. (6.9 ± 4.6 cm.kg) more than the torque needed to turn the pinion when the bearings were not preload- ed. Remove tooling (B) and (C). Put clutch housing (7) in position on the floor as shown. Put a block of wood 2 1/2 in. (63.5 mm) high in the center of the housing. Put gear (6) in position on the block. Put the pressure disc in position in clutch housing (7). Install the eight discs and the seven disc assemblies in the housing starting with a disc. NOTE: Put clean SAE 30 oil on the discs and disc assemblies (8) at installation. 14. Put the large brass washer on the face of gear (6). Make sure the hole in the washer is in alignment with the dowel in the housing. 2-82
