and burns ]

• Check spring connection and rivets, refer to => [ Checking spring connection and rivet ]

6 Bolt - 22 Nm

• Observe instructions for installation, refer to => [ Clutch with SAC Pressure Plate ] Clutch With SAC Pressure Plate.

Checking ends of diaphragm spring





• Wear up to half the thickness of the diaphragm spring is permitted.

• When performing repairs, always select the correct clutch pressure plate and clutch plate by checking engine code.

Checking spring connection and rivet





- Check spring connections - arrows A - for damage and make sure riveted fastenings - arrows B - are seated tightly.

• Replace pressure plate if spring connections are broken or badly bent, or if riveted fastenings are loose.

Check SAC pressure plate for warpage, cracks and burns





A Straightedge

B Feeler gauge

• Pressure plate warpage up to 1.0 mm is allowed

Removing dual-mass flywheel





• Do not use an impact wrench or pneumatic wrench to remove bolts - B -: this would severely damage the dual-mass flywheel. Bolts - B - must always be removed by hand.

- Rotate flywheel - A - so that bolts - B - are aligned centrally behind the holes - arrows -.

- When removing bolts - B -, make sure bolt heads do not contact flywheel - arrows - because this would damage flywheel when bolts are turned further.
