Withdrawal
Compress the locking lugs -arrows- on the reverse side of the clutch release lever and remove the release bearing -A- from it. To install, press release bearing -A- into clutch release lever until lugs -arrow- engage.
Clutch repair
Instruction. Before replacing the clutch disc and pressure plate, check whether there are centering sleeves for centering the engine/gearbox in the cylinder block, insert them if necessary. In the absence of centering sleeves, shifting difficulties, clutch problems and, accordingly, noise in the gearbox occur (crackling in drive wheels). Replace clutch/pressure plate with damaged or loose rivets. Select the clutch disc and pressure plate according to the electronic parts catalog and the engine code.
1. Flywheel. Make sure that the centering pins are securely installed; there should be no oil stains and traces of grease on the working surface of the clutch linings.
2. Clutch disc. Select the pressure plate according to the electronic parts catalog and the engine code. Installation position with dual-mass flywheel: The shorter end of the hub -arrow- points towards the pressure plate. Mounting position with conventional flywheel: Clutch cover facing pressure plate. Center. Lightly grease the spline connection with grease. Clean input shaft splines and, if using a used clutch disc, also its hub splines, remove any signs of corrosion and apply a very thin coat of clutch disc spline grease -G 000 100- to the splines. Then move the clutch disc in one direction and the other until the hub can easily walk on the shaft. Be sure to remove excess grease.
3. Plate. Installation is only possible in one position. Check the ends of the membrane spring, check the keyed and riveted connections. The plates are corrosion protected and grease lubricated. Only cleaning of their working surface is allowed, otherwise the service life of the clutch will be significantly reduced.
4. Screw. Select from the electronic parts catalog. Mb = 13 Nm, M7 = 20 Nm, unscrew and tighten in stages crosswise.
Mounting position of pressure plate
The TDC marking -B- on the flywheel must be between the two reference marks -A-.
Checking the ends of the diaphragm spring
Acceptable wear is up to half the thickness of the petals of the diaphragm spring.
Check keyed and riveted connections
Check the spring connections between the pressure plate and the cover for cracks, and the rivet connections for secure installation. A pressure plate with damaged spring connections or loose riveted connections -arrows- must be replaced.
Removal and installation of the friction clutch
Remove CP.
Insert support -3067- for loosening and tightening screws. Loosen the screws little by little, crosswise. Remove pressure plate and clutch disc.
Installation
Push the pressure plate onto the centering pins. Tighten all screws evenly by hand until the head of the screw is in contact with the pressure plate. Tighten the bolts progressively in a diagonal pattern so as not to damage the centering holes of the pressure plate and the centering pins of the flywheel. Install CP.
