Checking ends of diaphragm spring l  Wear up to half the thickness of the diaphragm spring is permissible.   Note Important: When performing repairs, always match up pressure plate and clutch plate by checking engine code → Electronic parts catalogue.

Checking springs and riveting I -  Springs OK l  Slight kinking on the outside -arrows A- is normal on production parts. II -  Springs damaged l  Renew pressure plate if springs are broken or badly bent -arrow B-.

–  Check that riveting -arrows B- is secure at all springs -arrows A-. l  Renew pressure plate if rivets -arrows B- are loose.

Checking SAC pressure plate for distortion, cracks and burning A -  Straightedge B -  Feeler gauge l  Pressure plate distortion up to 0.8 mm is permissible

Removing dual-mass flywheel   Caution 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 unscrewing bolts -B-, make sure the bolt heads do not contact the flywheel -arrows- because this would damage the flywheel when the bolts are turned further. –  Removing and installing dual-mass flywheel → Rep. gr.13.
