Interesting thread you guys got here. I've switched over to a automatic (old age I guess) but I used a Tilton with no problems what so ever before the switch. I did use a pedal stop and had a couple of custom hoses made instead of using the cheap "fittings and hose kit" that came with the bearing. My pedal stop was just a block of wood that would stop the arm. (old Sox and Martin trick)
A word to the wise; all hydro. throw out bearings have a rating that will limit the pressure plate weight rating you can use. If your clutch pressure plate is too heavy it will cause premature o-ring failure/leakage. The Tilton I used would be maxed out at about 3000 lbs I was told by Tilton. Matter of fact they also told me that their bearing was really designed to be use with a duel friction Centerforce clutch. Most of them are rated at about 2500 static they said.
I can't help but think some of you guys that have had o-ring failures and leaks also have heavy clutches I'd bet. Understand, hyd. T.O. bearings will work with a heavy clutch, for a while,,,,,,,,,, A alternitive to a heavy clutch is to use a so called "Pro" clutch pressure plate, but that is a subject for another thread.

Cul8er - Your pressure plate was too heavy. That's the reason the buttons wore on the fingers. The throwout bearing was operating past its pressure hold limit, causing the T.O. bearing itself to flutter. Your really lucky you know, you found a problem before all of that stuff came unglued in a power shift. Food for thought.
