Just started work on a JD 49 snow thrower. The bearing on the shaft from the angle GB to the chain drive sprocket is totally shot. I've never dealt with one of these flange bearings with the locking collar. I got the rusted up collar to move by using vice grips to turn it. The problem is, the bearing is at the welded on sprocket end of the 18" long shaft. The shaft is rusted up and to move the bearing all the way to the other end for removal is going to be no fun. I wire wheeled a short portion of the shaft and got it to move about an inch with a fair amount of pounding. It's too far from the end of the shaft for my puller. I thought of turning the shaft somehow and sanding it smooth again. It's 3/4" diameter and my drill press chuck is 5/8" so that's out. It's too long to fit in my mini lathe. I may have to come up with an adapter of some kind to fit it into the drill press. Any suggestions?
