sonett - yet another diaphragm clutch

The clutch is finally working again. The problem was the clutch pressure plate. The release bearing was pushing in too far, which cause the center ring on the fingers of the pressure plate to hit the friction disc. The center ring wore away, the fingers got bent in not uniformily causing a shudder and poor engagement.
