Mcleod hydraulic throwout bearing problems. We appreciate all of our customers for their support during this difficult time. Since the slip on bearing actually threads onto a sleeve perhaps it is the tolerancing of the threads between the bearing and the sleeeve. We would like to show you a description here but the site wont allow us. Let us know if you have any questions. Then we put 2 c clamps on the throwout bearing piston so that we could lightly push the pedal confirm that it was the fitting leaking. Pump the pedal 3 to 4 times with the bleeder valve open and the end of the opening submerged in a cup partially filled with brake fluid.
Tune in to watch chad and joe as they take you through the process of using our rebuild kits for our hydraulic throw out bearings 1300 and 1400 series. If you have any questions or concerns our tech lines are open at this time. Continue the bleeding process until all of the air is removed from the system. It was not the fitting and we could not reproduce the leak. We could reproduce the leak when only 1 c clamp was on though as the piston would slightly tilt making a poor seal. This will release fluid and air trapped in the system.
Mcleod tech suggested that maybe there was preload or lack of upward travel on the master cylinder pushrod not allowing the piston to retract far enough to get a full charge of fluid from the reservoir. 1 the seals of the bearing could be very sensitive to any angle ing of throwout bearing. The problem is that we never got any pedal resistance or even a twitch of movement at the throwout bearing after many many attempts at bleeding the system. Mcleod racing continues to fulfill assemble and ship product during this time. When the driver releases the clutch pedal the hydraulic system is deactivated and the throwout bearing is pushed away by the diaphragm spring thus resuming contact between the clutch plate and the flywheel. The sloppiness in the threads is noticeable because you can wobble the throwout bearing by hand.
