IMPORTANT: 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.

Install 2 bolts into the clutch pressure plate mounting hole 180 degrees apart.
Using a long pry bar, turn the secondary ring of the dual mass flywheel clockwise until the flywheel mounting bolts can be accessed. It may be required to turn the secondary ring past the bolt holes in order to compensate the spring tension.
