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.

In order to access the flywheel to crankshaft bolts re-index the dual mass flywheel using the following procedure:
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.
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.
