Armature bearing removal

[Fireball]

Would anyone know how to remove this bearing? It's on the armature of a Gould 1 HP motor/ Hayward pool pump. I have a press and pullers but is this a threaded on locking collar in front of the bearing(which I can't seem to unscrew)? Or is it pressed on after the bearing? It doesn't look to be a part of any bearing that I am familiar with. Every YouTube video has a snap ring in a groove to lock the bearing in place. Anybody done one like this before? TIA

not sure, it seems to look as tho it's threaded on there. it may be loctited in place & probably has reverse threads to the direction the shaft spis so it doesn't spin off .
I would get a cutting wheel and a hammer on that bearing to knock it apart & then you might be able to see better

As a last resort I know I could cut the ring off, and the bearing too if necessary. I'm not sure though after pressing on a new bearing if there has to be something to lock it in place. Thanks for your input.

I have done a few pool motor bearings, but have not seen a collar like that. If it is a pressed on spacer may be able to pull it with the bearing. Could put the puller on and heat it to see if it moves. Can you find that part on a parts list, see if it is a threaded part or shaft. Just throwing stuff out there.

Looks like a grove in the collar to move it with a chisel maybe? Did you try any heat on the collar, and try to un-thread it, or pull it as Hughmongus states above?

If worse comes to worse and you have to split the collar, l think McMastter Carr sells bearing retainer collars.

I did put the map gas torch to the collar and try to unscrew it (both directions) with channelocks and the armature in the vise. It just felt like the collar was going to deform and mangle and I didn't want to do something that was unfixable because I didn't know what I was doing. I might try to pull on the bearing next and see if the collar will move. If it won't it's just going to have to get cut off.

It kind of reminds me of the shafts on my delta sander. It had very shallow, fine threads the bearing slid over and a very thin lock ring.
The notches on a lock ring may be covered over with corrosion.
I might see some notches as shown:

You hit the notches with a punch or blunt chisel, right?

How hard is the steel on that retainer? Maybe you could give lt a few strokes with a file to get an ldea of the hardness to see if could drill about a 1/4" hole about an 1/8" deep and see if you can give it a good smack with a punch and a good size hammer, to try and un-thread it?

I would like to thank all of you for the input and suggestions, I finally got the bearing and collar off. The fine threads on the armature shaft are deceptive, the unthreaded collar was pressed on after the bearing. I let PB Blaster sit on top of it overnight and got a little better 3 jaw puller and they both came off together. Hopefully I can get this pump back together with about $75 in bearings, seals, and gaskets, which will be better than $750 for a new pump. Thanks again.

Do the fine threads serve any purpose?

None that I can tell.

good for getting it apart. wonder if the fine threads are used for installation of bearing & collar at the factory?
