901 steering hard when turning

[Teresa McCrary]

Only hard on one side. It’s a 901 Powermaster. We pulled these parts but don’t see anything that looks bad. Any ideas?

The control valve for the cylinder is on the inside of the cylinder where that large stud is sticking out in your first picture. You have not taken it apart far enough to see the individual parts that make up the control valve. My guess is that something (or things) is/are worn inside of there and are causing a leak when the control valve tries to move the rod in one direction, but not the other. Here is a link to the parts diagram for the cylinder:

Link to parts drawing of steering cylinder for a 901 series tractor

The parts that make up the control valve assembly are labelled 11 through 17 in that drawing.

Is it the steering wheel that turns hard or the wheels?

I took some more pictures. I don’t know if this will tell you anything though.

You can jack the front up and it will turn fine but when wheels are on ground one way is easy and one is hard.

Thank you so much. We got it broke down. Do you have a suggestion on a replacement kit? I’ll add some pics too

Thank you! This will help us put it all back together. Do you have any place I can order the rebuild kit? I’m sure the spring is bad and whatever comes in a kit. Thanks

I ordered the seals but would like to get the ball stud and the spring. Do you see it anywhere?

Those you most likely will have to track down as used items. Try contacting Unger Tractor in Missouri.

Best to make a new thread to attract the correct attention.
