  Note
t  Refer to general repair instructions → Chapter.
t  The gearbox must be removed to work on the clutch → 6-speed manual gearbox 0B3, front-wheel drive; Rep. Gr.34.
t  So as not to damage the SAC pressure plate on removal and installation, always observe the fitting instructions for the SAC pressure plate → Chapter „Removing and installing pressure plate and clutch plate (LuK version)“.
t  With the SAC clutch pressure plate (self-adjusting clutch pressure plate), an adjuster ring has to be reset if just the clutch plate is replaced → 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  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 is not to be cleaned, as otherwise the service life of the clutch would be considerably shortened.
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.
t  The clutch module is only to be blown out using compressed air.
   
t  If there is visible damage on the surface of the input shaft in the vicinity of the needle bearing for the dual-mass flywheel -arrow-, both the input shaft and the needle bearing in the dual-mass flywheel must be renewed → Chapter.
t  For input shaft replacement, refer to → Chapter „Fitting sequence - dismantling and assembling gearbox “.
  A30-10212
t  Check the input shaft for scoring around the bearing in the drive plate -arrow-. Renew the needle bearing in the drive plate if necessary → Rep. Gr.13.
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  Remove grease from input shaft bearing journal as far as splines.
  A34-10780
t  A lack of grease at the bearing points at the release bearing -arrows- may cause “creaking noise” on pressing the clutch.
t  Grease bearings -arrows- on release bearing assembly thoroughly with lubricating paste -G 000 150-.
  A30-10221
t  Do not put down clutch module with flange -arrow- for drive plate facing downwards.
t  This could bend the flange -arrow- for the drive plate, which would cause problems with clutch operation.
