trailer bearing help needed

[oldjeep]

I don't think you are getting what they are saying - in this picture, the red arrow is pointing at the piece of your old bearing that is still on the spindle.

A 1750 spindle should look something like this. We don't care about A, B, or C.
E is where your seal rides.
F is 1 3/8" dia and where your inner race should sit.
G is 1 1/16" and where your outer race sits.
The thread should be 1" dia.
The shaft between F & G is some size in between and really doesn't matter. Quite often it is almost the same size as F.
In your end shot F looks tapered! that is why I requested you post a side view. Several others have agreed.
The measurement D should be about 4 to 4 1/4" . That is from the end to the shoulder where E starts.
Check it out & let us know, POST A PIC

I say take off the other hub and take a side view picture of each axle.

Shows the inner bearing seated all the way to the lip for the seal Side view

Sig - When you took off the old bearing did any rollers fall out? It sure looks like it's tapered like the inner race of a taper bearing in the bottom pic. If what the bearing is seated against in the first pic is the seal surface, it's the first time I've seen a tapered seal area.

Put the hub on with the outer bearing and without the inner bearing and you're gonna see where the inner bearing and seal should ride. Pop the other side to compare and you'll see the inner bearing race is stuck/fused to this axle.

You have a three step axle like the one on the right of bwrek's drawing. The four step on the left only has a short "f" - 1 3/8" area. Functionally they are identical, but less machining on the three step.

Yep, that thing that's between your new bearing and where the seal is supposed to ride is remnants of your old bearing.

There you go Sig. Your sevond side view shows it, the old bearing race. It's shiny compared to the rest of the shaft and it is tapered. Get the chisel and tap ot off and you will be ready to go!

 

[oldjeep]

x7million - that is not the seal surface it is 1/2 of the old bearing

ya,, every one agrees it's either a race or what's left of the bearing ring....I'd concur with jeep. that pic above shows its what's left of a bearing ring. the ball bearings are gone and what's left is that ring.. that's exactly what happened to my axle (before I pulled it off and installed a new axle). get penetrating oil and tap it off.... Sig, I'd seriously consider installing a new axle and new hubs.. anyone whose recently installed a new axle will concur that new axles are nicely milled and bearings sit perfectly... old axle spindles get worn and dinged up.. over time even a slight bit of wobble will tear up bearings quickly...just a thought...

Ding ding the lights been on but apparently no one has been home

what's that suppose to mean? ding ding? topic over?

I finally caught what u all were saying that i missed wasnt a stuck race its part of a disintegrated bearing its not coming off and grooved the spindle shopping for a new axle now

 

[redneck joe]

glad i'm not the only one who gets stuck on stuff like that.

Exact same thing happened to me,, I installed a new axle, ZERO issues now... you will be glad you did.... grease zerks are a wonderful invention

No I think your still missing something.

Here is a nice new cup & cone bearing,



The cup is in the hub and the cone is on the shaft or spindle.

Here are the parts of the cup & cone,



When the bearing Kaboomed as you put it, the Rolling Elements and Cage were destroyed. You must have had some metal inside the hub when you took it apart. Those parts are what grooved the spindle. If the grooves are in the middle section and not to severe or deep then you should be able to continue using the axle.

Now the Inner Ring is the part we are all talking about. It is still on the spindle. Get a chisel & hammer and knock it off. It should come off fairly easy. If not, heat it with a propane torch. It will expand and allow you to hammer it off. Let the spindle cool naturally, NO cooling with water, etc.

Take a dremel cut-off wheel to the race and cut a slot from front to rear. It does not need to go all the way through. Then take a heavy hammer and smack the living bejeesus out of it. Unless overheated and blued, the race will be dead hard and will break right off

 

[Snowfish]

take the other hub off and see if you are overlooking something obvious...

Best advise yet.

Looks to me like you need two different size bearings. The on on the inside should be bigger. I think you have the wrong size bearing for the inside.
