Suggestions on Adding a Hydraulic Valve on a WD

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello. I usually frequent a different tractor related forum, but most of the tractor guys have left and it is mostly lawn and garden stuff now. 
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.

	A simple no cost way to check out if the problem is the packing on the piston in the rams. Lift the boom up and let it drop a number of times. Put your hand on the ram, if it is much warmer than surrounding metal it is, it is the ram not your control valve. If the seal is bad on the piston of the ram oil leaks past and the friction creates heat. 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 the lift cylinders on my loader as being the rams, then I know they are not the problem. I honed and re-cupped them and replaced the wiper seals when I got the tractor running. They will hold position if the engine is off. If you are referring to something else as being the rams, then you will have to elaborate for me.
