Information 

• Drain the clutch slave cylinder fully before installation. Check the bellows for signs of fluid and clean with a lint-free cloth if necessary. 
• Check the seal of the clutch slave cylinder. This may have remained in the clutch slave cylinder when removed. 
• During installation, do not bend the pushrod of the clutch slave cylinder more than 3° from the installation position. Greater deflections of the pushrod can damage the clutch slave cylinder. 
• Make sure the clutch slave cylinder is positioned correctly during installation. 
• Check that the pushrod of the clutch slave cylinder is definitely centered in the release lever. 
• Ensure that the cap is seated correctly on the pushrod. 

• A turquoise-colored plastic trim with a bore of approx. 1.5 mm must be visible in the line connection on the slave cylinder -arrow-  . Check that this is seated correctly and is not damaged.
