Resetting adjuster ring in SAC clutch pressure plate
Resetting adjuster ring in SAC clutch pressure plate
  Note
t  “SAC” stands for “Self-Adjusting Clutch”.
t  When fitting a new clutch plate in conjunction with a used SAC pressure plate, the adjuster ring in the pressure plate has to be reset by turning it back as far as it will go. If you do not reset the adjuster ring in the pressure plate, the SAC pressure plate will operate with reduced clamping force, which will cause excessive wear, especially of the clutch plate (clutch will then slip).
t  If the clutch plate is not renewed, it is not necessary to reset the adjuster ring.
t  New SAC pressure plates are pre-set accordingly, and do not have to be reset.

  Caution
Do not use force when performing the following steps, as this could cause the forks on the adjuster ring to break off.
–  Apply two screwdrivers to the forks on the adjuster ring. Use the press to apply pressure to the pressure plate until it is just possible to move the adjuster ring.
–  Using the two screwdrivers, turn back the adjuster ring evenly in -direction of arrows- until it reaches the stop.
–  Hold the adjuster ring against the stop and relieve the pressure applied by the press so that the adjuster ring is held in this position.
