CLUTCH FITTING GUIDE

COVER ASSEMBLY

• Remove rust preventative from the pressure plate surface.

• Ensure locating dowels are fitted.

• Tighten bolts one to two turns at a time in diagonal pairs to manufacturer’s specified torque.

DRIVEN PLATE

Concentric Slave Cylinder Installation Tips

• Keep clutch facings clean. Contamination can cause shudder and slipping.

• Ensure that the correct side of the clutch plate is facing the flywheel.

• Clean splines and lubricate with spline grease. Be careful to use a minimum of spline grease; too much will radiate outwards in operation and contaminate the clutch facings.

• Ensure clutch plate slides freely on gearbox spline.

• Use an alignment tool to centralise the clutch plate.

• Support the weight of the transmission when fitting to prevent distortion of the plate.

RELEASE BEARING

• Check the release bearing guide for wear. Wear in this area can cause a notchy or jammed pedal.

FLYWHEEL

• Inspect flywheel for hot spots, scoring, and warping.

• It is recommended that the flywheel be resurfaced to manufacturer's specifications. Alternatively, replace with new flywheel prior to clutch replacement.

SPIGOT

• Inspect the spigot bearing or bush for wear and damage. Replace if necessary.

BELL HOUSING

• Thoroughly clean the interior of the bell housing.

• Dirt or other material left in the housing can contaminate the clutch facings, causing clutch shudder.

TRANSMISSION LOCATION

• Worn or missing dowel locations will cause driveline misalignment, resulting in rapid wear of the new clutch assembly.

• Ensure dowels are fitted and in good condition.

• Clean all mounting faces.

OIL SEALS

• Oil can contaminate the clutch plate facings, causing shudder and slippage.

• Inspect crankshaft and gearbox seals. Replace as necessary.

RELEASE MECHANISM

• Wear or incorrect adjustment in this area can cause non-release of the clutch.

• Inspect and adjust (or replace) clutch fork, pivot ball, clutch cable, and hydraulic cylinders.

1. Do no compress the cylinder prior to installation as this can deform and break the seals, causing premature failure.

2. Ensure the installation area is clean and free from debris to make sure the CSC sits correctly.

3. Make sure the locating bolts are evenly torqued to manufacturers specifications.

4. Before bleeding the system, it is important to make sure the gearbox is located correctly and securely.

5. Bleed the system following the manufactures guidelines, making sure to not rapidly depress the pedal as this may damage the CSC seals.
