Tractor Steering

[dhillis]

As many of you as there are with tractors figured I'll ask real quick. FIL has a Mahindra 4500. I am trying to fix a steering problem on it so that I can use it to clear about 5 acres, put driveways, etc. A year or so ago my FIL had the HYDROSTATIC STEERING BOX rebuilt at a dealer after a seal under the drive shaft busted. We reinstalled it. 2 weeks ago I had the actual hydraulic pump on the engine replaced. We are still having a problem where the steering wheel never hits a wall and stops? From what I have read it might be a leak in the cylinder? Anyone have any other suggestions?

need some fill in here, after the machine was fixed a yr ago did everything work properly?
next why was the hyd pump replaced?
Mahindra tractors are an odd duck in the tractor world they are cheap and seem to have lots of problems with hyd systems, as far as my experience goes, I have worked on several different models and learned quickly to steer clear of them as they were always problematic. I have been repairing tractors for over thirty yrs, and running my own business you find out quickly how these import tractors hold up in the real world. I have not however worked on the hydrostatic steering system that was stated this one has but with hydrostatic systems a lot of the time when repairs have been done and the system opened up sometimes the system needs to be bled of air. I would look for a bleed screw some where in the steering system and start there.

It never did work correctly. I'll have to look for a bleed screw. I think my FIL bleed it by cracking open the lines?? I'll see what I can find.

No sir, I like learning...you know, just in case later down the road

Haven't had a chance to get by there to look for a bleeder screw but after thinking about it all hydraulics are on the same system. I would think if there was air in the system that it would also give me problems with other components. Still going to go look this weekend, just seeing if anyone else has an opinion or something to look for.

So from my reading online here is what I found. If it sounds incorrect or stupid someone please stop me!!!!!!

To test the steering pump I should disconnect the two lines that feed the cylinder. IF the steering pump builds pressure and stops then the cylinder has an internal leak. If the wheel continues to turn, then the steering pump is bad.
