B Allis Steering Shaft Bearings??

Does anyone no where I might find any bearings for the
steering shaft on a B Allis ? I ordered some from my local
Agco Dealer and there the wrong ones. The ones that came
out were a ball bearing and the ones they gave me were a
tapers roller. They said that was what replaced the other part
number but I'm pretty sure they won't work. Thanks for any
help!!
 
I have a 1958 catalog from a bearing supply
house, that lists, under "Allis-Chalmers"
"B spindle steering shaft" Cup #209889, and
Cone #209890. It shows a photo of a tapered roller bearing set.
It does not tell if these are "Timkin" or AC numbers, but those numbers don't show up in my
Timkin book, so I'd presume they're AC.
 
The part # on agco's web site is 70207802 witch now crosses to 760906m1 that is a roller but what came out of it is a ball bearing. The new one want fit the race on the shaft and I don't think it can be changed.
 
Depends on whether your tractor was equipped with a Ross or Gemmer steering gear.

If Ross, it takes 20 5/16" steel bearing balls.

If Gemmer, it takes 207802 roller assembly (Timken 5BC), 207565 lower bearing cup (Timken 6A) and 207570 upper bearing cup (Timken 7A). One of those cups is extremely expensive whereas the roller assembly is cheap. Timken products are available through your auto parts store. Timken will try to sell you a race to go with the bearing, decline this since the race is made integral with the worm.
 
Mine has the Ross . So all I need to do is get some 5/16 ball and put them in? Where is a good place to get them?
 
The bearing balls should be available from Agco Allis - part #915904. This is a standard hardware part. Hardware stores and bearing stores might stock them. If you also need the cup, part # is 210467.
 
We have a '39 B with a Gemmer steering box and it has ball bearings. I rebuilt it, no problem.
