Super 99

My Super 99 has way too much play in the steering wheel. I have adjusted it to the max, but you can still turn the wheel almost a full turn before it moves the front wheels. Also, when you turn it back and forth, the steering shaft rises and falls. Any ideas?

Sounds like the thrust bearing is out on the steering worm shaft. My 990 did the same thing when I bought it. Be careful if you take it apart, it has a ball screw in it. Larry

Larry's got it, I think. Picture a big nut on a coarsely threaded shaft, with steel balls inside it that run in the grooves- if the shaft is held in place properly, the turning action begins as soon as you begin to turn the steering wheel. But yours is free to move up and down, so it takes the first turn of the wheel to move the nut from the bottom of the steering box to the top, and THEN it starts steering.

Good idea to fix it sooner, rather than later- because some of the balls could fall out and jamb up the works, making it impossible to steer. Could be disastrous if you're on the highway with it.

Thank you for the replies. I tore into it, and the bearing is shot. Now to find parts. I'll try Owosso Tractor parts first.
