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.

Look at this vibra groomer brush roll. It's split in half. Talk about vacuum abuse. The guy said he used the wrong belt.

Thanks, I'll try dissembling the motor like you suggested. If I can't get the fan off, I guess I could find another scrap Sanitaire and use the motor and brush roll out of that.

I've taken the fan off Eureka uprights before and haven't had any problems.

Thanks guys. I'll try again tonight. I've never had one this difficult. If the fan was replaced in the past someone most have overtightened the pulley. I'm working on this Dayton for my uncle who supervised building maintenance. He said if I didn't fix this one he will have to buy one of my collection pieces. Which is a BIG NO.
