Troubleshooting: Hydraulic Clutch Bearings

Hydraulic Clutch Bearings Fitment Instructions

As installation of Hydraulic Clutch Bearings (also called concentric slave cylinders) may require specialist tools we will assume that you are a professional brake and clutch specialist and as such know how to install these units.

If you are a do-it-yourselfer or inexperienced in mechanical work we stress that you have the brake and clutch parts fitted by qualified installers only. This will ensure that the supplied items give many years of great service and severely lower the chances of incorrect fitment and premature failure.

WARNING: Brake and clutch items are safety critical items, as a result we recommend installation of LMB OE replacement parts to be done by professional installers and/or workshops only.
Failure to fit these items correctly can cause major damage to the parts in question and other parts of the transmission.
NEVER MANUALLY COMPRESS THE UNIT WITHOUT PROPER LUBRICATION. THIS WILL DAMAGE INTERIOR SEAL AND CAUSE THE UNIT TO FAIL.
