Flywheel: Service and Repair
Secondary Flywheel
NOTE: The secondary flywheel inertia mass contains the clutch friction surface. Excessive clutch slipping can result in warpage or other surface distress
which requires resurfacing or replacement of the secondary flywheel. The back side of the secondary flywheel contains a friction surface which is used in
the internal torque limitation system of the dual mass flywheel assembly.
