I recently purchased an Oliver 1800A at an auction. The tractor is in great condition, but I purchased a used Dunham Lehr loader for it and I am having trouble with the valve. The loader works fine, but I can't get fluid to return to the tractor when the loader isn't being used. The valve is a Cross brand. I believe that my tractor is an open center hydraulic system, not sure, and was wondering if I need an open center type loader valve. I think my current valve may be closed center, but not sure about that. The loader will work, but when Im not using it the fluid pressure builds because its not returning to the tank on the tractor. I removed a plug from the valve that allowed fluid to flow through when the loader isn't in use, but the loader won't move when I use the lever. I replaced the plug. I don't want to damage my hydraulic pump. Any help would be appreciated.
