Removing double-mass flywheel
Component overview
Overview of double-mass flywheel, 3.6 l
- 1 - Double-mass flywheel
- 2 - Fastening screw for double-mass flywheel, (8 M10 x 50 screws)
- 3 - Clutch plate
- 4 - Clutch pressure plate
- 5 - Fastening screw for clutch pressure plate, (6 M8 screws)
Information
The toothed segment 9538/1 must be bored to dia. 15 mm to guarantee a perfect fit and to avoid damaging the thread in the crankcase.
1. To counter, fit toothed segment 9538/1 to the crankcase using an M12 x 50 hexagon-head bolt (fine thread).
Toothed segment 9538/1
2. Loosen and unscrew fastening screws on flywheel. Carefully take off flywheel (watch the thread!). Undo fastening screw for toothed segment.

Information
Before re-installing the flywheel, clean the friction surface of the flywheel using a clean, lint-free cloth soaked in acetone or solvent naphtha).
1. Position double-mass flywheel on the crankshaft's dowel pin and press on to the crankshaft flange. Insert all fastening screws (8).
2. Align toothed segment 9538/1 and tighten fastening screw again.
3. Screw in and tighten fastening screws in diagonally opposite sequence. => Initial tightening: 19 ftlb.; => Final tightening - torque angle: 120°
4. Remove toothed segment.
