Flywheel: Service and Repair
Engine Flywheel Replacement - Manual TransmissionTools Required
* J44643 Flywheel Holding Tool
* J36660-A Torque Angle Meter
Removal Procedure
1. Remove the clutch.
2. Remove the starter.
3. Install J44643 in order to hold the flywheel.
Important: The dual mass flywheel may require re-indexing in order to access the flywheel to crankshaft bolts through the secondary ring of the flywheel.
4. In order to access the flywheel to crankshaft bolts re-index the dual mass flywheel using the procedure:
4.1. Install 2 bolts into the clutch pressure plate holes 180 degrees apart. Do not use the clutch pressure plate bolts. Use a bolt of the correct thread and length that protrudes enough to use a pry bar.
4.2. Using a long pry bar turn the secondary ring of the dual mass flywheel clockwise until the flywheel bolts can be accessed. It may require turning the secondary ring past the bolt holes in order to compensate the spring tension.
5. Remove and discard the flywheel bolts.
6. Remove J44643.
Caution: When removing or installing the flywheel wear protective gloves. The teeth on the ring gear may be very sharp and may cut you.
7. Remove the flywheel.
8. Remove the pilot bearing using a hammer and a punch from the flywheel. The pilot bearing is removed from the crankshaft side of the flywheel.
