Picked up a ‘75 Ramcharger & trying to diagnose an occasionally shaky clutch pedal when it’s depressed. The Z bar is floppy on the ball stud but there is no spring on the clutch fork but the most issue I think I have is the up & down movement of the throwout bearing on the shaft. Is there suppose to me that much room for movement in the throwout bearing or should the throwout bearing have had a smaller inside diameter? Or does the spring on the fork keep slight pressure to keep it in the right spot?
