O. K. Donald I need to think a minute, it has been over 34 years since I worked on one. Do the remore  outlets and the 3 point work? What happens if you raise the 3 point, hit the brakes and turn the steering wheel at the same time? Is this an early or late 1955? Remember this is a closed center system and if you have internal leakage you can have problems? Have you checked  pressures anyplace such as the remote couplers, the PTO and the power steering. How fast will the 3 point raise and is it a Cat 2 or 3 unit?
