I had the gear box rebuilt and it lasted 2 years crushing both the upper and lower bearings. I rebuilt it and it lasted 2 weeks. I noticed the wheels did not always rest at the positive stop blocks down on the wheels when the gear bos was at full travel. Is adding metal to thses stops a fixfor excess travel. I"ve taken up all end play in the pitman gears this makes the steering stiff but doesn"t take the last end play in the wheels. The tie rods to pitman gears have no play.

Something does not add up here.Your steering gear box with a good rebuild should last many years.Are you doing a complete rebuild on it and are you getting the correct amount of lubricant installed? I would also check the front spindles and spindle bushing's for excess wear.If you tractor has a loader all these componets need to be in excellant condition.Kent Gordon in Palestine Texas sometimes has good steering boxes.I have gotten a couple from him in the past.He can be reached at 903-729-8349.

What are you using for lubricant? It originally called for oil, but everyone seems to say use John Deere cornhead grease. It stays soft in cold temperatures, and doesn't leak.
Did you replace the recirculating balls in the block? I can't figure why your bearings would wear so fast unless they aren't lubed.

Hello,
I could be wrong on this but I think the bearings in a 550 steering box are "barrel" roller bearings. they look like standard tapered roller bearings but they are not.I don't think you can get the bearings anymore. I helped a guy fix one years ago we had to do some machining and put standard bearings in it.
good luck Ed

I rebuilt mine about 2 years ago and I am pretty sure that I got the bearings from AGCO. Mine is a Super 55 and you had to machine the opening on the top of the steering tube a little if I recall. I actually had to put in a new shaft from a Ford. The block end with the worm gear is exactly the same as the Oliver. I had to have the shaft cut and my old shaft welded back on.

Last I checked the bearings WERE available, but under different part numbers from AGCO.
Fresh rear end dope.full of oil.I'm not taking the gear box off the tractor.I lift the front end off the ground,take the steering column and top of gear box off,the lower bearing is fine.I center the front and reinstall,I watch that the surface on the worm gear does not rise above theheight of the cup for the top bearing while someone moves the tires to their stops .right then left.When the tractor is running I'm dragging boulders with the front bumper I installed.Everything is fine until I try and turn tight corners maybe the tractor isn't built for this type of work?

Did you adjust the worm bearing as outlined in the manual. It states that "Correct adjustment of the steering gear is very important."
Did you set the amount of pull to 3.5 to 5 pounds on a 9" radius from the center? If your bearings are too loose of too tight it will cause early failure.
If you had lubrication I would venture to guess the adjustment was wrong. Do you have the manual? I can email you the pages.

If you could e-mail me the ages from your manual re steering it would help. I'm rebuilding my steering box on an oliver 550 and have been following rebuilding it on the forum. Thanks
