Secondary Driven Gear Shaft
Tapered Roller Bearing Preload Adjustment
NOTE: If the transmission housing, torque converter
housing, secondary driven gear shaft, tapered roller
bearing, outer race, thrust shim, or thrust washer were
replaced, the bearing preload must be adjusted.
1. Remove the oil seals from both housings.
2. Remove the bearing outer race and thrust shim from
the transmission housing by heating the housing to
about 212°F (100°C) with a heat gun.
CAUTION:
• Do not heat the housing in excess of 212 F
(100°C).
• Replace the tapered roller bearing whenever the
outer race is removed.
NOTE: Let the transmission housing cool to room
temperature before adjusting the bearing preload.
