Hope someone can help. I installed aftermarket power steering on a Ford 3000 and bled the system, but I still have no movement at all of the cylinder. The system consists of a gear driven pump mounted to the engine, and a cylinder that pulls and pushes on a pitman arm, so it's very simple. The cylinder on this system has a built in control lever that extends and retracts the cylinder when the steering rod pushes or pulls on it. I unhooked the steering rod from the control so I could verify the lever moves ok, which it does. Tried unscrewing the lever a few turns to get more travel, still the cylinder won't move. Verified oil is in the reservoir, cracked open the cylinder lines and fresh oil comes out. I extended and retracted the cylinder by hand a few times to bleed it. Seems like I should have at least some motion by now. I was thinking of unscrewing the lever to look for debris blocking oil flow, but I have no parts manual to tell me what's inside. Please post your ideas on what to try next.
