I have a friend who had a John Deere 8410 tractor and he told me that something wasn’t right with it. Whenever its turned, the wheels themselves turn but not the tractor. A few seconds after you’ve turned the steering wheel all that’s happened is that it’s started moving again. He said turning left is no problem? I asked him if the engine oil and filter had been changed. He replied not in the last several decades, I recommend that you change the oil and filter. If the oil filter was an issue, it would have caused limited engine performance or difficulty starting. So, I am inclined to repair the hydraulic pump first. If that does not pan out, then it is likely that the problem lies in your gas tank filters.
Hi, I trust after changing the oil filter & cleaning the sump screen you checked on the steering pump. The system should be at about 2250PSI. Let me know if you would like any assistance with your repairs on your system.Is it alright if I disconnect the bleed-off hose for the steering column? It’s on top of the hyd.oil cooler on a 1/4 inch rubber line under the top tank.When you’re done, turn the wheel to the right until it’s very stiff but not enough that your car will start to move. Hold for a minute and if you see a steady drip of fluid from the hose, then there must be air in your brake hydraulic system. If there’s no leak around the steering wheel, then it’s probably a valve issue.
If the steering wheel locks when turning to the right and the wheels are turning slowly, your problem is probably motor oil leaking internally.
