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.
