There were no collars, just a light press on a sleeve which was a light press fit on the shaft. No idea why there were spanner wrench holes in it. We were able to break it loose with the wrenches we made and tap the end of the shaft to remove it.
New member, not sure where to post this, move it if there is a more appropriate place. Customer with a 50 year old piece of equipment, need to remove this bearing to repair the equipment. Looks like I need 2 spanner wrenches to remove collars, then pull it off with a huge bearing puller? Am I...
