Tony, Gurneejoe might have identified your pressure issue. As I recall from your email I received earlier the fast hitch hydraulic circuit was removed and capped at the remote valve. My tractor hydraulics book is with my tractor where we are restoring it and can't look up the system to see if the relief valve for the system with the fast hitch set-up is down stream from the remote valve on the right side of the touch control unit. It might be in that block which mounts to the transmission cover in front of the operators seat where the hoses from the remote valve go before going under the seat/tool box to the hydraulic cylinder on the fast hitch. From looking at your photos the whole hydraulic system needs a good cleaning including the pump and that block which contains something like a check, poppit, or relief valve might need to be in the loop for your testing process. You might want to clean and flush out the whole thing and install that block and all the hoses and see what kind of pressure you have on the system at that time. Just more thoughts but seems like you are making progress, good luck and thanks for the follow-ups,Hal.
