I have a IH-3400A backhoe in decent condition but the power steering has gone out. It started failing by working intermittently and now, it is completely gone. Yes, it has fluid. Sometimes the steering wheel will turn if you put a great about of force on it and the front tires will turn. At other times, the steering wheel will easily turn but not front wheel action.
I do have a limited service manual for the machine showing the flow for the steering. I was thinking of getting a 0 to 4500 p.s.i. gauge and working down the line to see where I am not getting pressure but I don't know what I am doing.
Any ideas that don't cost an arm and a leg?
Thanks
Joe
