Removing clutch slave cylinder





The clutch slave cylinder -arrow- is located to the left of the transmission, at the center section of the clutch bell-housing (shown here on removed transmission).





Information
^ Once the lead is separated from the clutch slave cylinder, the clutch pedal must not be pressed until reinstallation is complete.
^ During removal, do not bend the clutch slave cylinder more than 3° from the installation position. Greater deflections of the pushrod can damage the clutch slave cylinder and cause brake fluid to run into the bellows.

1. Unclip the line -arrow- on the clutch slave cylinder (remove retaining spring) and seal using a suitable plug. Pay attention to the seal on the line. This can remain stuck in the clutch slave cylinder. Carefully remove the seal and replace with a new one, if necessary.





2. Remove the fastening screw -arrow- on the clutch slave cylinder.





3. Press the clutch slave cylinder carefully outwards -arrow 1-. During removal, do not bend the clutch slave cylinder more than 3° from the installation position.





4. Remove the clutch slave cylinder to the rear -arrow 2- without tilting it. Wipe off any emerging brake fluid with a lint-free cloth.





Installing clutch slave cylinder





Information
^ Drain the clutch slave cylinder fully before installation. Check the bellows for ingress of fluid and clean with a lint-free cloth if necessary.
^ Pay attention to the seal on the clutch slave cylinder. This may have been left behind in the clutch slave cylinder during removal.
^ 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.





Plastic trim on clutch slave cylinder

^ 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.





Rubber seal on clutch line

^ A rubber seal (not to be confused with the seal over the plastic trim!) must be fitted on the push-on connector on the clutch line -arrow-. Check that this seal is seated correctly and is not damaged.

1. Remove the seal from the clutch slave cylinder and fit it in the correct position on the line. Use a new seal,if necessary.
