I am hooking up remote hydraulics on my WD45. I have a three way Cross control. Where would be the best place to hook the return line up to the pump. How about the pressurized out line. I was planning to hook into the current lines that go to the rams for the pressurized out line. Would this work. I can only figure to hook the return line to the current fill hole. Is this best, how would I do it. One of the Cross controls can be converted to open or closed so I want to use the present rams on my lift arms and keep it single acting. Is that open or closed. Would I just plug the in line on the control and divide the out line to the rams. Will I need more hydraulic storage capacity. Thanks.

I read a reply on this subject somewhere about a guy that welded a pipe bushing into the belt pulley hole plug. You would probably have to secure the plug using some large washer and bolts in the nearby holes in the frame rail. Seemed like a good idea if you don't need the belt pulley.

I have seen people run the return line back to the drain plug on the bottom of the reservior. This seems to be a good solution. I plan to do a hydraulic update to my WD in the future with 2 way valves for remote cylinders. I will run the return line to the drain plug. I will also put an inline spin on filter in the return line. Northern Tool has most of the need components online.

Required storage capacity depends on the volume of the cylinder you plan to extend. Return line does not go back to the pump- it goes back to the resevoir. Works ok to go back to the filler pipe if nothing else is available. To get pressure, don't need to tap in to the lift cylinders- there should be an open port available next to the two hose ports that the cylinders draw from. Closed center hydraulics are a rather recent innovation, so I would guess that AC hydraulics were open center.
