Dave, I thought all those were rebuildable. What makes you think that yours is not?

Seems to me there was a post on the old board about the steering box not being re-buildable. The shaft on my YM-2000 that has the pitman arm on it wobbles, so that leads me to believe its more than just an o-ring or seal that is causing the problem.
If it is capable of being fixed, that would be sweet. I've priced used steering boxes.... and "They ain't Cheap!"

I haven't looked into them except to look in a few old parts books. In those it looks as though the pitman shaft is supported on either end with a bushing, and the steering wheel shaft in ball bearings. Unfortunately the pitman bushings are not listed separately. The listing is for the steering box body or cover with a bush in it.
Maybe someone who kinows this job from having done it will jump in here with the answers. ll
Still, the worst case would be that a simple brass bushing would have to be made to size. It isn't a critical job, so should be a simple task at the local machine shop.

Hi,
Listen guys. Just take out the fill plug and tap a 90 degree zerk i.e. a grease fitting. Pump the sucker a few times every time you tinker it. End of problem.

The YM2000 gear box is rebuildable. The YM2000 parts book doesn't show that the parts are available, but i can supply you with the correct parts. Contact me at sheaftractor@coiinc.com

I checked my steering box today and it's fill of grease! A 90 degree and an extension with zerk is a great idea.
My steering is little sloppy, but when I take the slope out with the adjuter screw - there's too much drag...probably needs some tlc.

The cutter shaft on my bush hog mower used to leak oil and grease at the rate of a gearbox full every few hours of cutting. When I looked at the seal it looked good and it had me stumped for awhile. Then I added an air vent to the previously unvented gear box and it doesn't leak one bit anymore....
Thinking about the zerk and grease idea got me to thinking about venting gearboxes. If you go the zerk route, you might want to think about adding a vent to the box as well. It could be as simple as a hole drilled in the steering box top somewhere away from the rain. Most greaseable joints have some way to relieve the pressure. Otherwise you could push out the seals on the steering and pitman shaft.
I think if you add a vent and a zerk to that steering box you would have a system that the original Yanmar engineers would approve of.
