I'm working on a Dayton "Sanitaire" upright and can't get the fan off. I've tried tapping the wrench with a hammer while holding the fan and it won't move. I've also sprayed some PB Buster and Liquid Wrench to free the pulley and it still will not come off. I can't see a place to stick a screw driver in to keep the armature from moving.
Any Suggestions? I know this vacuum hasn't been used in the past fifteen years. Maybe the pulley is just frozen.
