      I am not sure if restorations of mechanical projects are big on this forum, however I am curious and will try regardless.

      I recently found an older fan and wanted to restore it to function instead of watching it get scrapped at the near by dump.

      Now I've broken it down and with a few apparatuses I collected, basically cleaned it up with whatever else I could find around.

      My question is, after putting it back together in original form, and restoring it, I find the magnetic motor to be a bit loud. Can I fix this or will I need a replacement part? I am open to suggestions and help.

      Video below for information.

      In the video I am applying pressure to the steel rod with my thumb that attaches the aluminum fan to the rotor. It is connected to the center electromagnetic copper. I believe it has something to do with two ball joints on either side of the steel rod that are the culprit but I am not 100% sure.

      Thank you and have a nice day.

      Well, you posted it in the section that's supposed to be for forum announcements.

      I didn't watch your video, but if it's making noise the bearings or thrust washers are likely worn out. On most old fans the bearings are oil impregnated bronze bushings.
