Farmall 560 Power Steering

Heat Houser · Mar 13, 2011

Just got the hydraulics working (the tractor sat for years) and the power steering pulls to the right. It will spin the steering wheel until it hits the stops. You can turn to the left but the wheel is biased to the right.

Question, is there a centering adjustment to correct this? I would have to assume so but don"t have the manuals on the steering system, only the engine, tranny, PTO, etc.

Looking at the parts book, it appears that there is a link that operates the spool. Since the book mentions a jam nut, I assume this would be the ajustment I am looking for.

Any guidance is appreciated.

The centering is not adjustable. The jam nut is tightened to bottom out. However, no doubt the control valve is not centering. May be due to a broken washer under that nut. First thing I would check though is the steering shaft itself where it enters the bolster. It should move in and out as you turn it back and forth. You may have external shaft problems so it cannot move in and out. The knuckle is splined at bolster shaft and should be free to move on splines. That is the way it is supposed to work, they don't all do it very well. It is acceptable for the entire shaft all the way to steering wheel to move back and forth if for some reason , like worn out splines, the knuckle has been fastened solid. I have seen them pinned on or clamped tight so as to keep from replacing that shaft and knuckle. It of course costs several hundred dollars to replace. There are other issues internally but I think this is your problem. You can take that control valve from underneath to repair it if necessary.
