SEAT Workshop Service and Repair Manuals

Removing and installing „LuK“ clutch (vehicles with turbo diesel engine) Special tools and workshop equipment required t  Counterhold tool -3067- t  Torque wrench -V.A.G 1331- t  Grease for clutch plate splines -G 000 100- t  Centring mandrel. -T10097-

t  For engines having a crankshaft of smaller diameter or having needle bearings in the crankshaft - → Fig.centring mandrel -3176- Detaching l  Remove gearbox. –  Insert counterhold tool -3067- to slacken bolts. –  Loosen diagonally in several stages. –  Remove pressure plate and clutch plate. Installing Installation is carried out in the reverse sequence; note the following:   Note t  Select clutch plate and pressure plate according to engine code and → Electronic parts catalogue „ETKA“. t  Check whether dowel sleeves for centring the engine/gearbox assembly are fitted 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).

Installation position of clutch plate l  The inscription „Getriebeseite“ should face the gearbox

Check ends of diaphragm spring l  Wear to half the thickness of the diaphragm spring -arrows- is permitted.

Checking spring connections and riveted connections –  Check spring connections -arrows A- for damage and riveted connections -arrows B- for secure seating.

Checking position of adjustment mechanism (new pressure plates only) l  The two edges -A- of the adjuster ring should be located between the two notches -arrows B-. l  If the adjuster ring is in a different position on a new pressure plate, the pressure plate and clutch plate must not be installed. l  The adjuster ring may take up a position outside the notches in used clutches.   Note t  Renew clutch plate and pressure plate if riveted joints are damaged or loose. t  Renew pressure plate and clutch plate together only. t  Select clutch plate and pressure plate according to engine code and → Electronic parts catalogue „ETKA“. t  Clean input shaft splines and, on used clutch plate, hub splines. Remove corrosion and apply only a very thin coat of clutch plate spline grease -G 000 100- to splines. Then move the clutch plate on the input shaft from side to side, until the hub moves smoothly on the shaft. Excess grease must be removed. t  Pressure plates are protected against corrosion and greased. Only the contact surface may be cleaned, otherwise the service life of the clutch will be considerably reduced. t  Pressure plate contact surface and clutch plate lining must make full contact with flywheel. Only then insert bolts.

–  Reverse position of counter-hold tool -3067- when installing.

For engines having a crankshaft of smaller diameter -arrow- or having an needle bearing -arrow- in the crankshaft

Centring clutch disc and removing and installing pressure plate for engines having a crankshaft of smaller diameter or having a needle bearing -arrow- in the crankshaft   Note Disregard arrows -A- and -B-. Continuation for all vehicles Install pressure plate as follows so it is not deformed during installation (leads to jolts when moving off): –  Position pressure plate on dowel pins. –  Screw in all bolts evenly by hand until bolt heads make contact with pressure plate. –  Tighten bolts in small steps diagonally in order not to damage centring holes of pressure plate and centring pins of dual-mass flywheel → Item. l  Install gearbox.
