The dual mass flywheel is bolted on the rear of the crankshaft with eight bolts. A dowel on the crankshaft flange ensures that the flywheel is correctly located. A ring gear is fitted on the outer diameter of the flywheel. The ring gear is not serviceable. Thirty blind holes are drilled in the outer diameter of the flywheel adjacent to the ring gear. The holes are positioned at 10° intervals with four 20° spaces. The holes are used by the crankshaft position sensor for engine management.
