Hydrolic TO Barring

the hydraulic throwout bearing rides against the fingers. It will have some pressure against the fingers. I can't tell you how much. You will probably have to play with it. Install with as many shims as is needed to have it ride against the fingers. Then bleed the system until maximum exstension has been achieved and see if the clutch disengages. If it does not then add another shim until it does. What kind of hyd t.o bearing did you get? If you have a part number maybe I can look it up and possibly help you out a little better.
