inside air fan bearing lub ?

[Kneale Brownson]

Did you try putting power to it?  Somebody told me some of those motors 
have a magnetized bushing arrangement that resists spinning (turns with 
some effort but will not "freewheel" if flicked with a fingertip, for 
example), but may be fully functional.  Power releases the magnetization 
that keeps it from spinning freely when unpowered.
