Model T Ford Forum: Forum 2014: Removing those $#&*#! wheel bearing races
Top of pagePrevious messageNext messageBottom of page Link to this message  By Dick Fischer on Thursday, October 16, 2014 - 07:16 pm:

Could someone please relate their method for removing the "Large Ball Race" from an early ball bearing front wheel hub ? If you look at the attached drawing, you can see that there is very little exposed edge to knock the race out from behind. The punch just glances off the curved edge without imparting sufficient force to move the race.

I know there are lots of "theoretical" methods for removing a pressed in race. I've used various methods on other jobs myself. But I'd really like to hear from someone who has actually done the job on a T front wheel hub.

Thanks in advance.

On some hubs there is a notch to engage the race to drive it out, many early hubs don't have the notch. If you're not planning to save the race you can weld the I.D. of the race, it will collapse the bearing race and should fall out easily.

Dick, there are a couple of ways if you're not trying to save the race.One way is to weld a bead around the race and let it cool. The other is to heat the race in two or three places red hot with a torch and let it cool. With either method, the race will most likely fall out by itself when cool. Dave

I'm with David on this one. The welding trick works like an absolute charm

I had a Bear of a time getting mine out. The inner cone is almost Impossible.

Greg & David - Trouble is, not everybody welds or has a welder!

Hit it with about 1/2 inch of wire feed welder. It falls out.

Jack D. - Thanks for the input. Did you eventually get your inner cones out ? How ?

Dick

Royce,

How did you keep from toasting the ends of the wooden spokes ?

Dick

It doesn't get hot anywhere near the spokes.

I learned to weld out blind bearings a long time ago. If done correctly the welding only takes a couple of seconds and will not generate enough heat to burn the spokes.

Harold, that's why I included the torch method<g>(I know, not every one has a torch either!)Chances are, most every one knows some one that does though. Dave

PS. It works best to weld the races with a wire welder using shielding gas and not flux core wire to reduce weld spatter that could make your day a lot worse.
