Trouble removing eccentric collars on bearings

[wiggy]

I had same problem on front of mine, it was a pig to get out, I am not looking forward to my other 5 to do this summer!!

I've removed many from old project and parts machines. If proper procedures don't work well, I unbolt the flanges to give me some room to work, and then get out the cut off wheel. A well placed cut on opposite sides of the collar and a good hit with a hammer and chisel will always get them off. Typically, if the collar is that bad, you need to smash the outer race of the bearing with a hammer and use the cutoff wheel on the inner race as well.
