I have to ask, the little bimba air cylinder for the orientation arm, what keeps it tight? Mine has no lock nuts on the adjustment and there aren't any pinch bolts so the cylinder is pretty loose in the threads. The parts break down doesn't show anything either. Seems that looseness will wear crap out pretty quick with it working back and forth.
Is there something mines missing between #2 and #7 or should the cylinder just jamb up and tighten against #7 block?
