Good morning! New here, I recently bought a frantom 10"combination saw/cabber. It's in pretty good condition and had the original SC wheels on it. I wanted to upgrade the wheels with diamond wheels, first 2 wheels 80# and 220#. I started dismantling at the saw end but I realized I'd probably have to remove the buffer/polisher end as well. I removed the buffer head, removed all set screws and loosened the flange bearing mount (?) But I cannot get this ring that is in front of the assembly off. Just kind of stuck atm and was looking for advice so I don't destroy this beauty. I have pictures and vids of progress and where I'm stuck if you'd like to see.

I don't think you can post videos with cloudinary. Most people put them on youtube and link from there.

Heat it up with a propane torch, occasionally turning the arbor. Should slide off after a few minutes.

Interesting! so just hold a torch to the threaded area or to that ring thing with the vice scratches? Heat just a bit or til red hot? I'll give that a try and update. I was afraid i may have to get a bearing puller but I think i can handle a torch!

The ring is called a locking collar. Heat this up, not the threads, do not get it red hot.

Perfect thanks so much! Buddy let me borrow a torch, knocker loose, and 2 24" pipe wrenches to lock the spindle from moving so hopefully I'll have this sucker off tonight! Appreciate the advice!

getting bearing puller after a little persuasion on that may not be a bad idea
Auto Parts stores have been known to loan them...

So all you guys suggestions worked however it's looking like I might need to get the bearing puller after all. I used the 2 vice grips, knocker loose and eventually the torch and I got the locking collar free and will spin freely. Unfortunately the locking collar won't thread down the shaft for some reason. I've got all the set screws out and the threads are pretty clean. I just soaked the threads and set screw holes in knocker loose for the night and wire brushed the threads again. So close!

Most likely the set screw 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.

Locking collars have eccentric holes. They line up for install/uninstall when one part is rotated relative to the other part.

Hi hummingbird! Thanks for your reply but I'm afraid I don't follow. This is my first time working with bearings and collars and such, so are you saying I need to align the set screw hole with something? Also I may have misspoke earlier about the locking collar spinning freely. The locking collar will now spin freely from the shaft (but won't thread down the last 4 inches or so of threaded shaft), but the locking collar seems to be spinning with the bearing race (?) or opening now. It's like the bearing front ring (race?) is attached to the locking collar and those now spin together separately from the shaft. I hope that makes sense.

Hi, punishedfrantom. I didn't say that very well. Not enough coffee yet when I posted that. Should've said eccentric locking collars need to be rotated. If yours spins on the shaft already it probably isn't an eccentric.
Here's a link to a page that describes them better than I can.
