Special tools and workshop equipment required





^ 3190 A - Mandrel





^ 3067 Counterhold tool





Notes:
^ Clutch plates and pressure plates with damaged or loose rivets must be replaced.
^ Select correct clutch plate and pressure plate according to parts list and engine code.

1. Flywheel
^ Make sure centering pins are a tight fit
^ Contact surface for clutch lining must be free of grooves, oil and grease
^ Removing and installing
2. Clutch plate
^ Installation position on dual - mass flywheel: shorter hub end (arrow) points toward pressure plate
^ Installation position with single piece flywheel: spring cage faces the pressure plate
^ Centering
^ Lightly grease splines

Notes: Clean input shaft splines. On used clutch plates, also clean the hub splines. Remove corrosion and apply only a very thin coating of grease Part No: G 000 1000 to the input shaft splines. Then move clutch plate up and down input shaft until hub moves freely on shaft. Excess grease must be removed.
3. Pressure plate
^ Assembly possible only in one position
^ Removing and installing - Fig. 1
^ Check ends of diaphragm spring - Fig. 2

Notes: Pressure plates are protected against corrosion and greased. Only the contact surface may be cleaned, otherwise the service life of the clutch will be considerably reduced.

4. Bolt
^ Select correct type from Parts Supplier On dual - mass flywheel
^ 13 Nm On single piece flywheel
^ 20 Nm
^ Loosen and tighten gradually and in diagonal sequence





Fig. 1 Centering clutch plate and removing and installing pressure plate
- Loosen and tighten bolts gradually and in diagonal sequence.
- Reverse position of retainer 3067 when removing.

Notes:
^ Pressure plate contact surface and friction material of clutch plate must make full contact with flywheel. Then loosely thread in mounting bolts
^ Pressure plate can only be installed in one position on the flywheel.
^ Then insert and tighten bolts evenly and in diagonal sequence to prevent damage to the centering holes in the pressure plate housing and to the centering pins in the flywheel.
