Removing and installing pressure plate and clutch plate („LuK“ version)
   
Removing and installing pressure plate and clutch plate („LuK“ version)
Special tools and workshop equipment required
t  Thrust plate -VW 402-
t  Press tool -VW 412-
t  Thrust pad -VW 510-
t  Assembly tool -T10254-
t  Thrust piece -T40089-

   
t  Centring mandrel -T40171-
  W00-10586
Removing
–  Remove clutch module → Chapter.
1 - Clutch pressure plate
  Caution
Take care not to damage pressure plate and dual-mass flywheel.
t  Pressure plate -1- must be compressed before removing or installing.
t  If the pressure plate is not compressed, it will become distorted when the bolts -2- are slackened or tightened (causes clutch grab when driving off).
t  The dual-mass flywheel -3- must rest only on the bearing washer -arrow A- when compressing the pressure plate -1- in the hydraulic press.
t  If the dual-mass flywheel is supported on the flange for drive plate -arrow B- the flange will become distorted and the flywheel will thus be damaged. In this case, the dual-mass flywheel will have to be renewed.
–  Position the clutch module so that the thrust pad -VW 510- makes contact with the bearing washer -arrow A- in the dual-mass flywheel.
–  Place the assembly tool -T10254/3- on the spring tongues in the diaphragm of the pressure plate -1- and apply the press.
l  Distance of travel: dimension -x- = 8 to 9 mm
  Note
A second mechanic is required for the next step.
–  Remove all 6 bolts -2- and release press.
–  Remove pressure plate -1- and clutch plate.

   
Installing
Installation is carried out in reverse sequence; note the following:
  Note
t  Check that pressure plate is not distorted → Fig..
t  When only the clutch plate is being renewed, the adjuster ring in the pressure plate has to be reset before assembly → Chapter.
–  Use centring mandrel -T40171- to centralise clutch plate.
l  Installation position of clutch plate: damper assembly (coil springs) or marking „Getriebeseite“ (gearbox side) point towards pressure plate.
–  Position pressure plate on centring pins.
  A30-10173
–  Position the clutch module so that the thrust pad -VW 510- makes contact with the bearing washer -arrow A- in the dual-mass flywheel.
1 - Clutch pressure plate
  Caution
Take care not to damage dual-mass flywheel.
t  The dual-mass flywheel -3- must rest only on the bearing washer -arrow A- when compressing the pressure plate -1- in the hydraulic press.
t  If the dual-mass flywheel is supported on the flange for drive plate -arrow B- the flange will become distorted and the flywheel will thus be damaged. In this case, the dual-mass flywheel will have to be renewed.
–  Place assembly tool -T10254/3- over centring mandrel -T40171-.
–  Apply press until pressure plate -1- just makes contact with dual-mass flywheel -3--arrows C-.
  Note
A second mechanic is required for the next step.
–  Screw in each of the 6 bolts -2- in succession and tighten to final torque.
–  Release press.
–  Install clutch module → Chapter.
