Hi John,
Sorry to hear that you are still having issues. My 2 cents on clutch installation. With a modern clutch I have always adjusted the linkage to ensure that there is no pressure plate contact with the throughout bearing in the disengaged position (pedal free play). I would adjust linkage to ensure that the clutch disengages around half travel of the clutch pedal.
As I found out with the three arm old style clutch, centrifugal force will cause those arms to fly away from the pressure plate as rpm’s increase. I believe this is why there is a measurement between the throughout bearing and the pressure plate arms. If the arms are too far from the throughout bearing they could open and tear themselves up like I experienced when I fired up my rebuilt engine without the transmission installed. Also the other important thing to ensure with the three finger pressure plate is that each arm is equidistant to the throughout bearing face plate.
If the 30U plate is of the style like a modern pressure plate then there shouldn’t be any concern for the pressure plate arms opening with centrifugal force. Please verify these ramblings before taking any actions.., this is my limited understanding based on my past experiences.
Good luck, Chet…
