I have a WD with a loader that I have been using for small jobs around the house for about 8 years now. The large loader tractor and Kubota skid steer that we use on the farm are only about a mile from my house, so I can grab them if I need them, but having the WD around for moving stuff is pretty handy.

My issue has become that my hydraulic lever has gotten to the point where it will no longer stay in position. I have tried pretty much everything I can do to make it stay put. It not just a creep. It either wants to be full pressure up, or drop. I am not going to waste a bunch of money rebuilding the selector assembly. The hydraulics are strong. I would like to just plumb in a spool valve and run my loader from that. I am not that familiar with the AC high pressure/ low volume system and it only needs to be a one way valve on top of that. My loader is a trip bucket. 

If anyone has ever done this before and could steer me in the right direction to do it as efficiently and cheap as possible, it would be much appreciated. 

I also use to worry that the control valve was leaking in situations like you have.  Most times it is internal seals in the ram, and no oil is leaking to the outside.

If you are referring to something else as being the rams, then you will have to elaborate for me. 

Sorry, I guess I didn't explain it very well. Even if I hold the lever in one position, it still will not stop moving. I even tried clamping the lever in place to the quadrant with vice grips but it still would either be dropping or raising. I feel like it is something further into the valving other than just the lever itself.

I dont have a battery box, let alone a decal. This is a working tractor, not a barn queen.

I guess I need to rephrase my initial question. I don't want to keep messing with the lever set up anymore.

Can anyone tell me how to add a hydraulic spool valve to a WD?

Thank you.

So you dont just leave the pump on and let it dead head against a valve? Is this to prevent heat build up or does the pump not bypass internally at a given pressure?

I am not using the rear lift. I have a counter weight box permanently mounted on the rear anyway. I really on need to be able to run the loader.

Do you have a manual for the tractor?  The directions are in there for setting up the pump and the linkage.  You need to have the linkage set up for 'Hold'.

After you get this set, you'll have NO problems using it.
