  Note
t  Refer to general repair instructions → Chapter.
t  Select the correct clutch plate and pressure plate according to the engine code → Electronic parts catalogue.
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 pressure plate and the dual-mass flywheel must be cleaned (degreased) thoroughly.
t  If the clutch has burnt out, thoroughly clean the gearbox housing in area of clutch and parts of the engine facing the gearbox in order to prevent odours.
