Clutch Overview, LuK






Clutch Overview, LuK

Replace the clutch disc and pressure plate if the rivets are damaged or loose.

Replace the pressure plate and the clutch disc together.

Either a "Sachs" or a "LuK" clutch may be installed.

Allocate the clutch disc and pressure plate to match the engine code. Refer to the Parts Catalog.

Clean the input shaft splines and (on a used clutch disc) the hub splines. Remove any corrosion and apply a very thin coating of grease for clutch plate splines (G 000 100) onto the splines. Then move the clutch disc back and forth on the input shaft until the hub moves freely on the shaft. Remove any excess grease.

The pressure plate is corrosion protected and lubricated. Only the running surfaces may be cleaned. Otherwise the service life of the clutch will be shortened considerably.

The pressure plate contact surface and the clutch disc lining must completely touch the flywheel. Install the bolts.

Make sure the alignment sleeves for centering the engine/transmission are installed inside the cylinder block. Install them if necessary.

If the alignment sleeves are missing, it will be difficult to shift, there will be clutch problems and the transmission may make noises (loose rattling).

For the correct clutch, refer to the Parts Catalog.
