Clutch: Repairing (in conjunction with a flywheel)
  Note
Single flywheel, the pressure plate and the clutch plate are matched and cannot be combined with components from other manufacturers.
  Note
t  Always replace clutch disks and pressure plates with damaged or loose rivet connection.
t  Select correct clutch plate and pressure plate by checking the → Electronic spare parts catalogue (ETKA) and the engine code.
t  Check if the centring sleeves are installed in the engine for the purpose of centring the engine with the gearbox and insert these if they are not installed.
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).

q   Spring cage aligned towards pressure plate
q   Centring → Fig.
q   Lightly grease splines
  Note
Clean input shaft splines and in the case of used clutch plates, also the hub. Remove corrosion and apply only a very thin coating of grease -G 000 100- to the splines of the input shaft. 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.

q   removing and fitting → Fig.
q   Checking ends of diaphragm spring → Fig.
q   Check the elastic and riveted joints → Fig.

Central clutch disk and remove and install the pressure plate
–  Remove -T20176-the assembly tool from gear selector mechanism.
–  Reverse position of counterhold -T20176- when removing.
–  Insert the pressure plate in its guides.
–  To centre the clutch plate, use the centring guide -U 10050/A- with the adaptor -U-10050/T -.
  Note
The contact surfaces of the pressure plate and the clutch plate must rest entirely on the flywheel. Tighten the securing bolts uniformly and diagonally to avoid damage to the clutch plate centring holes and the centring pins on the flywheel.
