John deere 4430 steering hose problems

[spurs]

We have a 4430 john Deere tractor that the return hose keeps coming off between both valves . Can someone tell me what might be causing this problem ? Appreciate the help .

Are you talking about the rear couplers >? You need to make sure you lock them in , that is the little toggle on top of the remote . Or new balls , springs and O_rings in the female end . Make sure they snap when plugging in .

No it's the steering valve under steering column
We put the return line back on this valve and after you run it awhile it comes off just like something is causing pressure on it.

I'm sorry I didn't say what valves i. It's between both steering valves , the one under steering wheel and the other valve under hood. The return line is about 30 inches in length that keeps coming off .

My guess is valve in housing is sticking as there's not a lot to fail in the metering pump under steering wheel. By chance have you checked screen(parts key 3) to see if it's clean?

 

[spurs]

No I have not checked the screen , is it in the valve that you showed in the picture?

I see what your talking about thanks I will check it out . I will let you know thanks.

I would also suggest to check stand-by pressure which should be 2250 psi.
