I have one of the 'cursed' Sears routers that I purchased second hand knowing about its jammed depth adjustment issues. I have managed to free the depth adjustment and the router has been giving trouble free service. Unfortunately when I was freeing it up I had broken off the spindle lock which has been a PITA. I now have a replacement housing and need to learn how to remove the broken one. I am thinking the armature needs to be pressed out of the bearing so the end cover can be removed. Am I on the right track or should I just use the router as is? I add that I have been using it in purpose built router fixtures and not inverted in a table, probably why it has been working for me.
