• ◆ Installation position: Shorter hub end (arrow) faces pressure plate
• ◆ Centring => Fig.1
• ◆ Lightly grease splines

Note:

Clean input shaft splines and on used clutch plates, the hub splines, remove corrosion and apply only a very thin coating of grease Part No: G 000 100 to the input shaft splines. Then move clutch plate to and fro on input shaft until hub moves freely on shaft. Excess grease must be removed.

• Pressure plate
• ◆ Removing and installing => Fig.1
• ◆ Check ends of diaphragm spring
  => Fig.2

Note:

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.

• Bolt

• ◆ Allocate using parts catalogue
• ◆ Loosen and tighten gradually and diagonally

→ Fig.1     Centring clutch plate and removing and installing pressure plate

• ‒ Loosen and tighten bolts gradually and diagonally.
• ‒ Reverse position of retainer 3067 when removing.

Note:

Pressure plate contact surface and clutch plate must make full contact with flywheel. Tighten bolts diagonally and evenly to prevent damage to the centring holes in the pressure plate housing and the centring pins in the flywheel.
