SLAVE CYLINDER Removal and Installation

If a new slave cylinder is to be fitted, have the replacement cylinder at hand for immediate fitment to minimise fluid loss. Otherwise, either the hose end must be plugged, or the hydraulic system drained to prevent fluid being spilled. To drain the system, attach a bleed tube to the bleed valve on the slave cylinder, open the valve and pump the clutch pedal until all the fluid is drained out. To remove the slave cylinder, first disconnect the release lever return spring from the lever and the tag at the bleed valve . Slacken the hose connection at the cylinder. Remove the two bolts securing the cylinder to the flywheel housing and pull the cylinder off the push rod. Unscrew the unit from the hose connection. Install the slave cylinder in the reverse order of removing. Screw the cylinder fully onto the hose before attaching it to the flywheel housing. The connection should be fully tightened once the unit is secured in place. When installation is completed, bleed the clutch hydraulic system as detailed later in this section. Seal Replacement A cylinder overhaul kit containing all the necessary seals, etc., should be obtained before starting work on the cylinder. Detach the dust cover from the end of the cylinder, extract the retaining circlip and remove the piston, cup seal, cup filler and coil spring from the cylinder bore . Clean all the components with methylated spirits and inspect carefully. Check the cylinder bore for any signs of scores, ridges or corrosion pits. If the bore is in good condition, a new seal can be fitted, otherwise the complete unit must be renewed. Lubricate all the internal components with clean brake fluid. Insert the return spring, small end outermost, into the bore, then fit the cup filler, new seal and piston. The cup seal ig.'fitted with the hollow side towards the bottom of the bore. Secure the components in position with the circlip. Smear rubber lubricant around the sealing areas on the dust cover, then fit the cover onto the end of the cylinder.
