Servicing clutch
  Note
t  Refer to general repair instructions → Chapter.
t  Before renewing the clutch plate and pressure plate refer to Fault finding on power transmission - Complaints regarding clutch and clutch mechanism → Chapter.
t  Check that dowel sleeves for centralising engine/gearbox are in the cylinder block; install if necessary.
t  If the dowel sleeves are not fitted, this will lead to gear-change problems, clutch malfunction and in some cases gearbox noise (gears will make rattling noises).
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  On vehicles with SAC pressure plate (self-adjusting clutch) an adjuster ring has to be reset when only the clutch plate is renewed → Chapter.
t  To avoid damaging SAC pressure plate when removing and installing, observe assembly instructions for SAC pressure plate → 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  Pressure plates have an anti-corrosion coating and are greased. Only the contact surface may be cleaned, otherwise the service life of the clutch will be considerably reduced.
t  If the clutch has burnt out, thoroughly clean the bell housing, flywheel and parts of the engine facing the gearbox in order to prevent odours.
