I don't have a drawing but I can tell you how to do it. Remove the bolt, lock washer, and spacer. Remove the set screws out of the locking collar. You have to remove everything else and save the grease fitting and hose if it has one. My mechanics use a ziz wheel and please wear glasses especially when you get to the race of the bearing. When you get to the race which is the last piece, cut a groove in the top of the race parallel to the shaft and don't cut into the shaft. Then cut a groove 180 degrees from that cut. Take a chisel and 3 lb. hammer and put the chisel into the groove and hammer away. Be careful as the race can and will shatter and please again wear safety glasses. If you're good with a cutting torch, it can also be cutoff with that. Hopefully you didn't run it too long with bad bearings as they may have eaten the shaft. If there's a grove in the shaft where the race was, you'll need a new shaft and another bearing. If the shaft is good, clean it up with emery paper and replace your bearings.
I stock the knives for this machine and if you need any in the future, please keep me in mind as I'm not very far from you as we're in Atlanta.
Hope this helps!
