You are referring to the "pilot bushing", right?  Sounds to me like you 
need to positively eliminate anything else, first. I like a straight 
wooden stick, like a dowel -- easier on the fingers around spinning 
machines, if you are careful -- wood is a great transmitter of sound, 
ala they make violins out of wood, not rubber.  Real mechanic's 
stethoscopes are nice, too, especially when you are having trouble 
diagnosing noises.

If you haven't tried it without the belt, plain water, like from a 
garden hose, makes a good belt lube that will temporarily silence most 
belt noise that might interfere with your listening.  And I've heard 
some of the strangest noises coming from belts -- I remember replacing a 
timing chain in a Courier pick up because of belt noise, once.  (It was 
hi-mileage, and needed preventive maintenance anyway.)
