I have an older industrial Massey ferguson 40B that has a weak steering issue.
Wheels on the ground engine running - mid to low rpm I can see the wheels trying to turn but don't. WOT and turning back and forth it will suddenly decides to turn. Seems to turn left better than right, but not much better.
Wheels off the ground engine off - Through the steering wheel it feels like a rough gear is turning somewhere internally but the wheels do turn back and forth.
Wheels off the ground engine running - at idle at wheel lock I get about 1000psi when I can get it to turn. At WOT I get about 1600psi, so it's in spec range. Problem is that I have to sit there and turn back and forth until you feel a slight drag and the engine sounds like it's under a load and the pressure will jump up.
This makes me think it's not the pump. Does anyone have experience with bad orbital valves to know if this sounds like the issue?

After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
