Borg Warner T5 Hydraulic Release Bearing Kit


This kit utilises a concentric release bearing and aluminium boss, with modification to the standard gearbox nose. The kit comes completed with all fixings required to convert your existing T5 gearbox. The slave cylinder inlet and bleed should be located vertically and the hydraulic clutch pipe routed through 2 holes drilled in the best location within the bellhousing flange for your application.

Please note that the slave cylinder must be in a partially compressed form when installed. Fitment of the slave cylinder in the extended state will result in the bearing being forced off the end of the inner shaft when the clutch is depressed. When used in a custom installation please check the actuation of the slave cylinder over the entire clutch pedal stroke.

The slave cylinder and bearing work in a different way to a manual installation in that the release bearing is in constant light contact with the clutch diaphragm fingers. This is achieved by an internal spring within the thrust bearing. There is no need to be concerned that the release bearing is in contact with the diaphragm at all times.

*** Dimensions
Mounting plate height 40mm
Slave cylinder height 60mm open, and 40mm fully closed
Assembled heights 100mm open and 80 mm fully closed
The adjustment shims are 3mm thick

Note:It is necessary to shorten the original thrust bearing tube and substitute the original bolts for the longer ones supplied. See the second picture for an illustration of how to achieve this. There is no need to disturb the front gearbox bearing.

A mechanical clutch pedal stop must be fitted to prevent the slave cylinder over throwing, which will lead to fluid leaks and seal damage.

Please see the Fitting Instructions for more information.

If you require a plumbing kit please use the Plumbing Kit for Type 9 or T5 Hydraulic Release Bearing.
