  Note
t  Refer to general repair instructions → Chapter.
t  Observe notes on removing and installing clutch master cylinder and slave cylinder → Chapter.
t  On vehicles with SAC pressure plate (self-adjusting clutch, LuK version) an adjuster ring has to be reset when only the clutch plate is renewed → Chapter.
t  “SAC” stands for “Self-Adjusting Clutch”.
t  To avoid damaging SAC pressure plate when removing and installing, observe assembly instructions for SAC pressure plate → Chapter.
t  Check that SAC pressure plate is not distorted → Fig..
t  If the vehicle is fitted with a self-adjusting clutch (Sachs version), the clutch plate and pressure plate can only be renewed together → Chapter.
t  Renew clutch plate and pressure plate if riveted fastening is damaged or loose.
t  Select the correct clutch plate and pressure plate according to engine code → Electronic parts catalogue.
t  To avoid damaging dual-mass flywheel during removal, please observe instructions for removal → Fig..
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  Only blow out dual-mass flywheel with compressed air.
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.
