Removal & Installation
- Remove the transmission.
- On manual transmission vehicles, remove the clutch.
On automatic transmission vehicles, remove the torque converter from the flywheel.
NOTEThe flywheel bolts should be loosened a little at a time in a crisscross pattern to avoid warping the flywheel. Also, some vehicles will have an orange bolt hole on the torque converter, which should be matched with the orange line on the flexplate for proper balance. If the flywheel is not equipped with the orange markings, matchmark the flywheel to the engine block so that it can be reinstalled in the original position (of course for this to work the crankshaft cannot be rotated after the flywheel is removed).
Loosen the flywheel bolts (gradually, using several passes of a crisscross pattern) and remove the flywheel from the engine.
NOTEOn vehicles with manual transmissions, replace the pilot bearing in the end of the crankshaft, if removing the flywheel.
- The flywheel should be checked for cracks and glazing. Resurface or replace as necessary.
- Coat the threads of the flywheel bolts using a thread-locking compound.
Install the flywheel on the end of the crankshaft. Be sure and line up match-marks. Tighten the bolts a little at a time, in a crisscross pattern. Tightening torque:
- 3.8L and 4.6L SOHC engines: 59 ft. lbs. (80 Nm)
- 4.0L engines: step one: 10 ft. lbs. (13 Nm), step two: 52 ft. lbs. (71 Nm)
- 4.6L DOHC engines: 63 ft. lbs. (85 Nm)
- Install the clutch or torque converter.
- Install the transmission.
