I recently replaced my clutch when I could no longer shift without grinding the gears. I assumed my problem was a spring slipping out of place on the clutch disk. What I found was a broken rivet. I got a new disk and reassembled the whole clutch assembly with one difference; I measured the gap between the flywheel housing and the block. The gap was .020” so I added extra shims. Now I have severe shuddering when shifting into 1st and reverse Did I just screw up? Another observation: I adjusted for the normal 1” of free play on the clutch pedal but when I look at the throw out bearing, it starts catching when the free play is only 1/4”
TIA Ian
