Good evening gentlemen, I have recently acquired an AD3 Grader and the steering assist doesn't work. I removed the cylinder and put a seal kit in it and took the steering valve to my local trusted hydraulic shop. We tested the valve and found that the oil was bypassing straight to the ram. I left it with them and upon their teardown discovered that water had been in the valve and it was pitted pretty bad. Are there any outlets to find a replacement for this valve? any input would be greatly appreciated, Thanks in advance.
