Steering problem with my Farm Pro 2425

[quicksandfarmer]

I have tries to bleed the lines but and they have plenty of fluid going to them. I have no pressure going to the steering cylinder, and I am not sure if the priority valve has an issue or the steering valve (the one that the steering wheel attaches to) may be plugged. Any idea what pressures the lines going to the steering cylinder need to be at?

To answer your direct question, there is no such thing as "working pressure" in this hydraulic system. The pump moves a fixed volume of fluid with each rotation. If there is no work to be done the fluid moves through the system and back to the tank unimpeded, the pressure is virtually zero. If a valve is actuated it creates resistance to the flow of fluid and the pump increases the pressure to maintain the constant flow. When the steering isn't being turned the pressure should be zero. On my tractor, if I turn the steering against the stop the pressure relieve hisses at me, which I think is 2000 PSI. Depending on what you're asking of the steering the pressure will be somewhere in between.

While the tractor is running, with assistance from another person, the front wheels will turn. I am not sure if there is something that is plugging the, what I would call the diverter at the base of the steering column. We were able to turn the front wheels without turning the steering wheel so I know that something is bypassing. I just hate to start replacing parts when they may not be bad. I had the steering cylinder professionally rebuilt so that is not the problem. Both the loader and the 3 point hydraulics function correctly so I am down to two parts and winter is coming. Thanks for the info.

Thanks for the info, I will put a gauge in line and check working pressures.

I don't understand. 3 people have suggested that you disconnect a hose and perform various tasks. I don't see your response to those 'tests'. Did I miss those results?

I have not had time to complete the tests. I did talk to the guys at Circle G Tractors and they were helpful in figuring out the problem though.
