If you don't have access to HVAC equipment either, I've read that putting the bearing into a largy syringe with some oil is a lot better than nothing, even though it's not that much of a vacuum.
Very carefully. The fan is held by a set screw. It came out willingly. I kept the rotor shaft and set screw hole soaking in PBlaster for well over a week. Then rocked the fan until it loosened up. Still, I think I had to use two screw drivers to pry it off.
@@madmanmapper I'm trying to get the motor to make a wind turbine. I'll keep working on getting to the inner components, shouldn't be too difficult, plus it doesn't run when I plug it in but the copper looks in very good shape and it's the old school version like yours with the big motor, excited for the project!
