Sorry for the crappy pic of DS end , there was a dim line but it didn't show , the mystery bearing is about .125 " thick . its the bright circle . thk/s.

Thats the standard ford front roller bearing. Same part 28 - 48. Also needs a new inner race probably.

Hey Gus....The piece you show standing-up is called a TORQUE TUBE. At 72" long, it is out of a '41 thru '48 Ford.




A TUBE-type drive shaft was used no later than 1936 on Fords. A corresponding '41 thru '48 drive shaft should be a solid, steel shaft with a tubular coupler at rear end. '41-'48 DRIVE SHAFT should be 68-1/8" long with coupler.

You are missing the outer race

[cas3]

I dont know how you are getting those numbers, but there is only one size ever used in the tube. If it don't fit, there is something wrong with the tube. They are not in short supply

I got the those numbers with a T gauge and micrometer.. the yellow outline( i'm not a photoshop expert) is the bushing I'm measuring to get the ID. So I guess it appears someone has machined a thick bushing instead of std. split bearing , and pushed it in ?? so if that's the case, can I hammer it out from the other end? thanks all for the help.

[cas3]

You wont be able to hammer it out as there is a wall there that the seal is up against. Odd situation here, hard to give advice. If you can see for a fact that there is a bushing in there that should not be there, I would run a bead in there with an arc welding rod, and when it cools it will shrink enough to fall out

Apparently, there are some torque tubes out there that run a thick wall bush [outer race] and different roller bearing up front, with 68 prefix part numbers. I've never encountered it, but you can read about it here; https://www.fordbarn.com/forum/showt...+front+bearing
Sounds like that's what you've got.

[cas3]

Well geez Brian, thats interesting news....never heard of it !

[Brian]

Nah cas, I hadn't either. I learnt it on here [the 'barn']

[Bored&Stroked]

I wonder if the OD is the same as what most run . . . or if the whole thing is a red-headed step child?

It isn't much fun getting those bearing sleeves out - there was a special tool that KR Wilson had for the thin wall sleeves, but I don't have one. I used a high-speed air grinder to cut down the side of one - such that I could collapse it and pull it out.

If you get it out of there, you should replace the seal that is behind it before you put another one in there. Maybe the "thin wall" versions will fit???

Did you try Southside Obsolete in MN?

Wow "eureka" I thought it was a OEM , Thanks , Maybe I can modify it with a ground out dimple, There's a little bit of shoulder to mic next to the OD of bearing, and it mics similar to the B-4655 split OD ,,,if can't source a OEM bearing. I'll also give the shop in Min. a call.. thanks, all.

The regular split outer race, without the dimple, is available through regular bearing suppliers. I think the dimple was a sole Ford feature.

G'daY Brian; would one source this split bearing , by the ID of the DS were it nests ? thk/u, Gus.

hello Gus, years ago, when I was first rebuilding my car, I ordered the replacement bearing from a local bearing supplier. The outer race they supplied did not have the dimple to match the original Ford one I had removed...
In endeavouring to answer your question, I have just gone out to my shed and removed an outer race from a spare torque tube I have floating around. Blow me down!...it too does not have the dimple, so must have been replaced at some stage....of course, no numbers on it to make ordering a replacement easy....
Anyway, the NOMINAL measurements for the replacement roller bearing and outer race are; od 1 13/16 x id 1 1/8 x length 1 3/4. The thickness of the split outer race is 1/16".
