Federal Model 28 Possibly Warped?

Sun Nov 26, 2023 2:17 am

I picked up a Federal mod. 28 on marketplace yesterday, motor works good but was very stiff. Disassembled the entire thing completely, cleaned and re-packed bearings, freed a seized brush, etc. Got it all back together today and the impeller- when tightened down- has a slight wobble to it that causes it to scrape the intake shroud pretty bad. However, when the nut that holds the impeller on is backed off the impeller spins perfectly free on the shaft and doesn't strike anything.

Not sure what to narrow this down to.. Off balance motor? Bad bearings? Any help is appreciated- TIA.

This is a huge bump so sorry about that but I’m thinking that there could be a small dent in the stator which is hard to see…
I might be wrong

Again sorry for the bump
I'm a siren enthusiast but I also collect electric fans

Now I have 8 small sirens, and 47 electric fans :D
