WD Hydraulic valve

Rifman · Mar 18, 2015

Hello,
I have a WD with the factory valve that controls the 3 point. The left side of the valve body has two outlets. One that goes to the remote, and one that goes to the left hydraulic cylinder for the 3 point. The right side of the valve body outlet goes to the right 3 point hydraulic cylinder. There is no return line. How do these valves work?
The question I have is: Can I plug the right side valve outlet that goes to the right three point hitch cylinder, and then run a T-line off the left cylinder over to the right cylinder? I am wanting to add a selector valve, and plumbing the 3 point this way would help. Any problems from doing this? Thanks in advance. Rifman

That valve on top of the hydraulic pump is the "hold control" valve. It's operation and adjustment was complicated enough there was a decal on the side of the battery box showing the adjustments. Of course that is all in the operators manual too.

Of the three ports, the two across from one another will work for "hold position". The third port does not. Otherwise you can plumb off there any way you desire. AC recommended plumbing when adding a loader was to place a tee in the line on the right side, inside the frame, of the line which went to the right rockshaft cylinder. Then a coupler and lines fed the loader cylinders. So most anything is possible.
