Clutch - V8 (Description): Description and operation (page 2 of 4)

Flywheel The flywheel is bolted to a flange on the rear of the crankshaft with six bolts. A dowel on the crankshaft flange ensures that the flywheel is correctly located. A ring gear is fitted on the outside diameter of the flywheel and seats against a flange. The ring gear is an interference fit on the flywheel and is installed by heating the ring and cooling the flywheel. The ring gear is a serviceable item and can be replaced if damaged or worn.

The operating face of the flywheel is machined to provide a smooth surface for the drive plate to engage on. Three dowels and six threaded holes provide for the location and attachment of the pressure plate. The flywheel is balanced to ensure that it does not produce vibration when rotating. A machined slot, with a series of holes within the slot, is located on the engine side of the flywheel. The slot accommodates the tip of the crankshaft position sensor which is used by the Engine Control Module (ECM) for engine management.
