Hello bluefish628,
I assume that you are saying that the gripper bow does not turn to the left or the right and becomes stuck on the turntable!
You need to strip down the gripper bow assembly and check on the plastic moulding of the gripper bow arm there is two small pips on each side of the moulding if these are worn or damaged the index solenoids do not have anything to turn over the arm.
