Removing double-mass flywheel

Component overview





^ 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)

Note
The toothed segment 9538/1 must be bored to diameter 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).





2. Loosen and unscrew fastening screws on flywheel. Carefully take off flywheel (watch the thread!). Undo fastening screw for toothed segment.





Note
Check the friction surface of the flywheel. The flywheel must be replaced if it is damaged or discolored.

3. Inspect the friction surface of the flywheel visually.

Note
Before re-installation, clean the friction surface of the flywheel with a clean lint-free cloth that has been soaked in solvent naphtha or acetone.

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.
