I’m doing some reassemble on my press after having some work done on the bed and I don’t know what this part is called but it has something to do with the grippers in relation to trip/print mode. This is on the side opposite the operator at the head of the bed. It connects to the trip mechanism. I can’t find anything in my manual that helps me understand why there is a sliding bar and why there is a latch. Is this bolt and screw meant to be tightened down after some adjustment is made or is it supposed to slide around? It also affects the wedge just to the left of it and how much movement in and out it has. The parts as listed in my manual are screw x-11007 and QR-103 and latch x-11066 which all sit on block x-11171. Thanks!
