Most likely the set screws marred the shaft, that makes it difficult to get the collar off, puller helps. When you get it off, file a flat the same size of the marred place on the shaft, then reassemble with set screw over the flat, makes next teardown much easier. Haven't had this line thing happen for some years, still readable though.It's because you used brackets instead of parenthesis on screw as you can see Just use the quote or edit button and you can see the html

punishedfrantom, I don't know how aware you are about how setscrews mess up a shaft. Look at your fourth pic. down, between the bearing and the set collar you will see a circle on the shaft where a setscrew was tightened in at one time. the screw cup point also upsets, or raises some metal around that circle, the raised metal is likely what is holding the collar on, reason for filing a flat for the setscrews to go on at reassembly.

Bearing puller is OUT lol. The bearing puller I got yesterday doesn't reach the collar or bearing, at least it was cheap! Here's a question, could I wrap the threads near the collar with floss and try to bring it down the threads that way, just to get it started? I've seen people get like their wedding rings off their finger like that, I feel like that concept might work here?

Here's what I would most likely do. First I would locate and order a new bearing for that end. maybe a collar too, but with a setscrew on the bearing I'm not sure it was needed. Then I would get my hands on a dremel with small cut off wheels and cut into it lengthwise, on opposite sides, without cutting through to the shaft. A twist on a durable screwdriver or a tap on a properly shaped chisel would split it. Then it will be evident why it's not moving without excessive damage to the shaft removing it. It might be better to hand it off to someone who has those tools and let them disassemble it. On reassembly filing the small flats for setscrews and using a non sieze paste on shaft threads is advised, but not on set screws. Use 242 loctite there.

Try cleaning the arbor shaft better, there appears to be a lot of paint on it still. See if you can clean the section between the collar and the bearing, then tap the collar towards the bearing and thoroughly clean the arbor all the way down to the ends of the threads. If you see any nick's in the shaft, file them smooth.
You could always try wedging two large screw drivers between the bearing and the collar to persuade it down the threaded areas. Addition heat with the torch may work as well.
