Concentric Slave Cylinder Leaking?

We have included LUK Technical Bulletin 0018.

Which explains the correct procedure to follow for bleeding and installing a Concentric Slave Cylinder (CSC).

Through our warranty procedures we do receive Concentric Slave Cylinders returned to ourselves with the Seals which have burst apart or have leaked.

This is usually down to the incorrect installation procedure followed! Not a Part with a Manufactured Defect.

 Unless a Part fails through a  manufactured defect it will not be covered by a warranty!

When fitting a Clutch, Flywheel and Concentric Slave Cylinder always check to make sure their is a related Technical Bulletin and always follow any necessary procedures to prevent premature failure of the part.
