Anybody familiar with Hydraulic Throw-Out Bearings. I have a McLoed Racing throw out bearing in my rod. Early Hemi backed up by Muncie 4spd. Trying to find out if the problem I'm having is something others have run into. The Throw-Out bearing was originally set up with approximately 1/8 inch clearance between the T/O bearing and the pressure plate clutch fingers. (it's a diaphragm type pressure plate.) Well as time went on, the clearance gap closed up and the bearing is constantly against the fingers and is under slight pressure. The problem is that this constant pressure is pushing the crankshaft forward and wearing out the thrust surface on the crankshaft main bearings. I've been told that as the clutch "disc" wears, the pressure plate fingers extend backward closing up the clearance gap to the T/O bearing. This doesn't make sense to me. ANY THOUGHTS ?
