Instruction. Before replacing the clutch disc and pressure plate, observe the requirements in section "Transmission diagnostics, clutch and clutch drive claims". Check the presence of fitted bushings in the cylinder block for centering the engine / gearbox, insert bushings if necessary. In the absence of centering bushings, difficulties arise when shifting gears, problems in the operation of the clutch and, accordingly, noise in the gearbox (crunching gears). Replace clutch discs and plates with damaged or loose rivets. Select the clutch disc and pressure plate according to the electronic, spare parts catalog and the letter, engine designation.
1. Flywheel. Make sure that the centering pins are securely installed; there should be no grooves, oil stains or traces of grease on the working surface of the clutch linings.
2. Driven clutch disc. Compliance with the electronic parts catalog. Mounting position with conventional flywheel: Clutch cover facing pressure plate. Center. Lightly grease the spline connection with grease. Clean the toothed connection of the input shaft and when using the clutch disc. Remove corrosion from hub toothing and apply a very thin layer of clutch disc toothing grease -G 000 100- to toothing. 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. Check the ends of the membrane spring, check the keyed and riveted connections. The pressure 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. Bolt, 20 Nm, unscrew and tighten in stages in a cross pattern.
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 riveted connections for tightness.
