I have an old hy reach and the control block for lift reach and tilt has been replaced with a generic block which works fine. However I am missing the bypass block which connects the breakaway ram and the flail start/stop & direction of rotation. Any ideas where I can pick up a replacement? even Something not standard would be fine. I have the exploded part diagram if I sent this to a hydraulic supplier would they be able to work out what types of valves I will need?
