This kit allows the fitment of a concentric hydraulic release bearing to the Toyota W series range of gearboxes, replacing the original external slave cylinder. The original thrust bearing tube is removed and shortened with the original bolts being substituted for the longer supplied 8mm bolts. The bolts are refitted through the supplied adaptor plate and spacers. The supplied slave cylinder can then be fitted directly to the adaptor plate using the 3 x 6mm bolts in 2 different positions. There is no need to disturb the front gearbox bearing.

To be used in conjunction with our Duratec to Toyota W Series Gearbox

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.

Note:It is necessary to shorten the original thrust bearing tube and substitute the original bolts for the longer ones supplied. There is no need to disturb the front gearbox bearing.

Please see the Fitting Instructions for more information.

Please see this image for an illustration of how to configure the plumbing to allow bleeding. The feed and bleed use the same port with the hose nearest the slave cylinder connecting to the master cylinder and the other hose connecting to the remote bleed screw. Please note the plumbing is not included. It will be necessary to build your own plumbing kit or purchase the Plumbing Kit for Toyota Hydraulic Release Bearing
