get a good look at the end of your housing to make sure the race is not still on it. the bearing that you are showing looks to be a bearing/race combo.

It's still in there right now... I've got to pull it. Funny thing... EVERY video I watched, they either had the new style beating already or didn't have to change the bearing, so a race bring in the housing never came up. If I survive this 😳, I plan to post a video to YouTube of the process.

We ALL appreciate this, because it adds to our knowledge base!  

I'm following along as I'm not sure that I fully comprehend the questions. it seems to me that you should be able to slip the bearing away from the race right there in your hands and see the bearing is the same as the one on the axle. maybe I'm misreading something.

Excellent! Reading this discussion helps! The video linked shows the before and after I'll end up with apparently...

I currently have the old style with tapered bearing pressed to the axle and a separate race pressed into the housing. They come together when the axle is installed into the housing.

I'll end up with the new style...a single unit (with integral race) that is pressed into the axle. The axle then is pressed into the housing, which mates the integral race into the housing.

This explains why some videos on YouTube show the axle just being pulled out by hand (old style bearing), yet others had to use a slide hammer (new style bearing).

Evidently, this new style is all that's being sold now.

I'm glad to be of service!  😉

That's the thing... The new bearings are different.  No more is the race a separate piece. Not sure why the old style is gone, but evidently all manufacturers are only making them with the race integrated into the bearing.

At one point today I was 90% sure the Timken SET20 bearing I bought was wrong for my truck since the race doesn't come off. I spent all afternoon reading and watching YouTube videos the last one I posted, plus the one from the other discussion that Jim linked has made me 95% sure the SET20 is in fact correct, despite it's design differences.

Well, now that I was convinced I had the right bearing, I took some closer measurements.

Axle shaft seems to be the 1.531" as expected. ***BUT*** measuring the outer edge of the race I've not yet removed from the housing, it appears to be the "small" housing at 2.875".





(I need better calipers!)

If that's the case, I'm on the hunt again for the right bearing as the Timken SET20 is for the large housing (3.150").

My mind is blown. I'm done for the day! Time for a shower and to get some sleep. I've been on this all day and have only accomplished yanking the axle and getting confused. 🤦🏻‍♂️

Next step... Crawl up under this thing and examine this axle closer. What in the world is under this truck???

Get a $10 electronic plastic caliper at Horrid Fate.

They are fine for this sort of stuff. 💡

That would for sure be an upgrade from my $2 Hobo Freight calipers! 😂

Personally I like dial calipers.
No battery to fail.
But they don't convert instantly.

it is true that by the time 40 years has gone by, many swaps may have been done. one of the points about the bearing being captured in the race could be very good actually. the plate on the end of the axle that captures the bearing /seal and hold it into the housing is completely set as far as bearing /race load goes. and by installing them as an assembly puts the race exactly where it needs to be. no risk of it being too loose or tight. as for diameter I'm not sure what years had what specifically.  

Hi.
Your caliper is broken. I can see it in your pictures. You have pushed one inner pointer loose. You have the same axle as I have on Eddie. See Fixing Eddie in projects. Page 21.
And buy a new caliper. I like steel ones 🙂👍.

Hi. My wrong 😩. Your caliper looks ok 😄

Run a hot bead or two around the inside of the race and it will fall out by itself. 💡

I'm to old to screw around fighting to get something like that out anymore.   😒

After you end up breaking tools trying, you're just going to end up welding something to get a slide hammer onto anyhow.  😉

Hi. The race came easily out of
   Eddie. After you have got it out you will be sure about the bore size.

Yes! You’re exactly right! I was not accounting for the fact that the outer diameter of the race is smaller to account for the seal. I was measuring what effectively is the inside diameter of the seal instead of the outside diameter of the race. 😆



The Timken SET20 is in fact correct for my application! Now on to installation!

47 minutes... That how long it takes a clueless IT guy to get to this point...



Time for some breakfast and then to stupidly try to press the new bearing on without a press. 😂

Go to The Big box store
Get yourself a piece of black iron pipe that fits over the axle.
Set the flange on a chunk of wood on the floor, axle up.
Bearing over axle, pipe on top of bearing.
How big a hammer do you have?  🤔

I've cut a piece of pipe already. On the hammer thing... One that's not big enough I'm sure. I've got a slide hammer here I may try to rig for this.

I'm shooting a video. It may end up in the "Comedy" category. 😁
