  Note
t  Refer to general repair instructions → Chapter.
t  The dual-mass flywheel, clutch pressure plate and clutch plate are matched together; components from another manufacturer must not be installed on the same vehicle.
t  Always renew clutch plate and clutch pressure plate together and select the correct parts according to engine code → Electronic parts catalogue.
t  To avoid damaging clutch pressure plate when removing and installing, observe assembly instructions → Chapter „Removing and installing clutch (Sachs version)“.
t  Renew clutch plate and pressure plate if riveted fastening is damaged or loose.
t  Clean input shaft splines and (in the case of used clutch plates) the hub splines. Remove corrosion and apply only a very thin coating of grease for clutch plate splines -G 000 100- to the splines. Then move clutch plate backwards and forwards on input shaft until hub moves freely on shaft. It is important to remove excess grease.
t  Clutch pressure plates have an anti-corrosion coating and are greased. With the exception of the friction surface for the clutch plate, the pressure plate must not be cleaned. Otherwise the service life of the clutch will be considerably reduced.
t  The friction surface of the clutch pressure plate and the dual-mass flywheel must be cleaned (degreased) thoroughly.
t  If the clutch has burnt out, thoroughly clean the clutch housing, flywheel and parts of the engine facing the gearbox in order to reduce the smell of burnt linings.
