Case 311 hydraulic conversion for remote cylinder

[blueridgetim]

Newby here. I picked up a 1957 Case 311 RN that had been sitting for a while and was able to get it running thanks to all of the great information here, so first, a sincere thank you to everyone.

To the issue at hand, this tractor has the Eagle Hitch and I would ideally like to add lines for a remote cylinder (see diagram below). I have both the owners and service manual and can see the parts required (hand control and linkage, additional control valve body, body gasket, hoses w/ fittings, and the rear bracket). Would anyone with the parts manual mind sharing the part number for the control valve body, as it is likely the linchpin in this whole endeavor, what other models might use the same part, or best of all a source to buy one? I searched online last night for a while and was unsuccessful.

Anything else that I should think about, or that I don't know that I don't know?

I appreciate it,
Tim

This pertains to 300 DA hydraulic controls only and some common misunderstandings.

The controls valves are the same in all respects, the top valve is mounted upside on the lower control valve to have the interlock block and hydraulic lines on the left side of the tractor. When mounted the spool in the control valve needs to be rotated so the slot on the end for the bellcrank is down as it is in the parts view.

DA & SA interlock blocks are the same in all respects with the exception that the DA interlock has a 1/4 inch recessed head npt pipe plug in port C. Pic 2.

SA interlock block port C needs to be open to keep the pump from going in relief when the oil in the SA piston is returning to the sump, in the this case the Eagle hitch control valve lever is in the lowering position. Pic 3

This is likely to be mostly a salvage yard hunt. Don Livingston, Austin MN, (507) 433-0073 may have what you need.

Joe, thank you very much. Very generous of you and, from what I've seen from you on countless threads, it's just how you roll. I will update if i can track the parts down.
