IME, it's always been the generator's bearings or bushings that squeal (the generator may have a couple of oiling ports, BTW), or perhaps the belt or any other device connected to it. good luck!

hueyhoolihan in trying to find the squeal while it was running i touched each brush pulled them off the commutator it immediately stops squealing i had originally thought it was bearings and bushings it obviously wasn't.
