I ruined a clutch by just adjusting the pedal free play I had always adjusted them that way and never had a problem. I put a new clutch in and the throw-out bearing rode on the pressure plate fingers until it damaged the bearing and chewed up the fingers. Now I remove the inspection cover and adjust the linkage so that the bearing clears the fingers by .030 or so. (I don't measure just adjust so there is a gap between the two) I craul out from underneath and cycle the pedal a couple times then double check it. This procedure works best for me. tmm
