Use some scotch brite on the armature area where the brushes contact before assembly too.

Thank for your information.
I have some crookus (sp) cloth and some emory cloth so I can clean up the shaft.
I am a little worried about the armature surface. There is some mild pitting on a few of the plates. It will take more than some scotch brite to "smooth" it up some. I just had a light bulb moment...... I wonder if I can put the armature shaft in a drill to spin it so I can sand the surface.
I need to go outside and start the soaking on the bearing. Heating the bearing might be the key to getting it off.
