I posted a similar thread in the wheel loader section, but got no response. I am working on a JD 544j. The steering system is not activating the pump. When in a bind the steering is weak but will kick in if you work a lift function at same time. I have found the steering compensator valve and removed the cartridge . The cartridge does not look like it could be disassembled and the orings are good. A small line comes from the steering valve and goes to the compensator block, also a small line goes from the steering motor to the main control valve. So my question is , how can I determine where I am loosing the load sense signal from the steering valve without replacing parts?
