4500 ford power steering adjustment

mrfabjr · Jul 3, 2019

My 4500 ford frt. end loader and backhoe has a power steering problem. It will turn to the right easily but it takes all I can do to turn it to the left. I think I have found the adjustment for it but I am not sure. What I think is the adjustment for it is a small rod (5/16 I think) off of the top of the steering cylinder. It has a long nut with a lock nut on each end. Does this need to be longer or shorter for the proper adjustment? Is there anything else I need to know about it?

Thanks

You said it steers easily in one direction, so I'm thinking we can rule out the pump. That rod is actually operating the control valve. With the loader securely blocked in the raised position, have an assistant turn the steering wheel lock to lock while you observe the action of the rod/spool assembly. Then, starting from a full right turn, slowly turn the wheel to the left until increased effort is noted, and instruct your assistant to hold it at that point. With the engine running, grab the rod with vice-grips, and move it in the direction required to make a left turn. Pay attention to the valve spool; it must move with the rod with NO lost motion. If when you move the rod and the system becomes pressurized for a left turn, the hydraulic system is OK and you need to adjust the rod in the appropriate direction. If you move the rod and no reduction of steering effort is noted, a cylinder overhaul is indicated.
