4410 steering issue

[Chuck4310]

Well I took the tractor out today and warmed it up. I turned the wheel all the way to the right to stop. Applying constant pressure, I turned the wheel to the left- 3 1/2 turns to stop. I then turned the wheel to the right- 4 turns to stop. I tried this several times and it always resulted the same.
The wheels turned freely with no difficulty unlike recent previous times when it was much colder out.
I also noticed that the wheel would continue to turn slowly after reaching the stop as Chris pointed out.
Why the different # of turns each way?
I tried it with the front wheels on the icy driveway and with the front end off the ground, same result.
Any thoughts?

My thought is it is working ok.
Not having a mechanical connection between the steering wheel and the front wheels, there will be differences in hyd. pressure and resistance. This likely will result in the differences in # of turns.
Now, have to wonder where the apparent moisture is that is freezing up and causing you a problem in colder temps.

Thanks for the reply, I agree.

Never had any leaks of fluids and I check them regularly so don't know where moisture in the system could come from.

I'm just gonna keep on runnin it! Been a good machine.:thumbsup:

Chuck, I think you misunderstood the test somewhat. The instructions want you to turn the wheel to full right and then keep constant pressure on the steering wheel for 1 full minute. If the wheel turns more than 5 revolutions after the wheels stop moving, there is too much internal leakage in the steering valve or the cylinder. The reason you see more turns for the left lock is that the cylinder is extending when steering to the left and retracting when steering to the right. Less oil is needed to fill the cylinder when it retracts since the cylinder rod is taking up some of the space in the cylinder.

Thanks jd110! Now it's making sense to me. I did notice that once the wheels hit the stop, the steering wheel continued to turn VERY SLOWLY.
Although I didn't time it, it was nowhere near at the rate of 5 turns in one minute.
Thanks for clearing that up for me.
