I have asked several questions about this backhoe before, and each time I think it's the last time, but I really hope this is it. I have replaced the pump and it all works well now except that the engine will quickly stall when a cylinder reaches the end of it's stroke. When I say quickly, I mean there is not enough time to let up on the control to prevent it. Since the pump is moving oil any time it is operating, and it will run while I am not operating a cylinder it must have a functioning relief valve, right? Should that same valve relieve the pressure when I reach the end of a cylinder? Would an easy (and reasonably correct) solution be to put a relief valve just before the controls that would run the oil back into the tank and adjust the pressure to the point that the engine struggles but doesn't stall right away?
