Kirby Fan
I worked for a Kirby dealer when I was 14 back in '79 doing all the repairs,Usually the fan was already broken,so the first thing I would do is hit it sharply with a hammer in the right direction and that usually worked,if it didn't the fan is broken by now,so on the older machines you could break off a piece of the fan to get to the screws behind it that hold the front plate on,so you can pull the Armature out so you can get a grip on it,we had a special tool to hold the armature, while it was in the machine,but you risked damaging the armature,the fans were cheap to replace.
