Do you have a welder? Weld a bead around the piece of bearing and should come right off because of the heat. You could also cut a slot in the piece with a sawzall or something and then use a good sharp chisel and split it.

I would think, since it is fairly loose, that heating it would cause it to expand enough to remove it. Or, since there's a crack in it already, get a good chisel vertical in the crack and hit it hard. That should crack it right off.

Sorry, I can't help you but........ Larry (fergienewbee), remember our conversation from yesterday??? Watch the video and tell me; do you 'get' it??? :>)

Wear eye, face, neck and body protection.

Hold a LARGE hammer against one side of the bearing as an "anvil". SMACK the opposite side with the other hammer and the bearing race will split or shatter.

Several things to try. What I'd personally do would be to get the torch and cut it. It's not that hard to cut a bearing race and not scar the shaft if you are careful. The second thing to try would be a bearing splitter/puller. Clamp it below the brearing and simply pull it off. If you don't have a torch you can try to cut it with a grinder or possibly shatter the race with a hammer but given the size of the race and the fact it is on the shaft like it is I wouldn't put much hope in doing that. With all of that said if the race will spin on the shaft like your showing in the video then it has probably created a small groove in the shaft where it rides as well as a burr right above it. If that is the case then the only way it is going to come off easy is to cut it with a torch. Good luck.

I would try Bob's method first I have removed several that way. Tho it doesn't look like you have much room to swing the hammer. If it's already cracked on one side and you have a 4" grinder, put a cutting wheel on it go to the opposite side of the crack and cut a groove from top to bottom without cutting the shaft.The try the chisel in the crack. The cut you make doesn't need to be straight up and down, just cut wherever it's convienent, you are only trying to weaken the piece.

Thirty seconds with an oxy-acet torch and it"s done. Removed hundreds of them over the years w/o cutting the shaft. Heat the ring until it starts to bubble, carefully hit the oxy handle, and move towards the shaft. You"ll see the outer ring bubble away before you get to the shaft. Start at the top (torch head parallel to machine deck) and work down in this case, since the shaft is obstructed by the machine frame.

Since I have a torch, that's what I use. I only fiddle with them 30 seconds or so, then torch it.

Since you are asking I assume you don't have one.

They make a special puller that grips the edge of a bearing, but need several sizes to work on all the bearings one comes across so it gets to be a spendy tool and doesn't always work anyhow.

With it that loose & cracked, it should be pretty easy to smash with 2 hammers as described. Be careful of flying steel, that hard metal will fragment & fly like a granade.

Or a cold chisel as someone else mentioned.

If you have a reagular wheel puller & have room to get it behind in that tight area, that would pull this loose one off. But looks pretty cramped to get there.

My tool of last resort is a Dremmel with a cutoff wheel. Can get into some fairly confined sapces, and a good cut across the face, and some hammering and cold chiseling usually gets the job done. Often with the abundant application of swear words....

(quoted from post at 09:47:17 06/02/10) Do you have a welder? Weld a bead around the piece of bearing and should come right off because of the heat. You could also cut a slot in the piece with a sawzall or something and then use a good sharp chisel and split it.

Welding a bead and then removing quickly may work but if it cools the race will shrink and be stuck tighter than it is now. Your method does work well for removing outer races.

Torch... The thing is... doesn't really matter much if you do scar the shaft a bit. A flap disc on a grinder or file will clean it up quick and easy... and if there's a bit of metal missing, that doesn't matter either.
So jsut torch it off. Second I'd probably pull it off with a puller/bearing separator or cut it with a dremel grinder... but honestly... if I see something like that I fire up the torch without even thinking about it. Life is too short to struggle with that stuff.

Weld a footlong piece of some smooth scrap metal, with the metal centered on the bearing race. put your gloves on, and lift the race off while its still hot. Make it look like this, from above: _______o_________
