understood...
i might suspect that a brush spring or two was too tight or too loose. IIRC, forces generated on the brushes of a generator can be easily adjusted to exert whatever force is necessary. might try adjusting a spring or two. and if that fails i might remove each brush, in turn, to isolate which brush or brushes are making the noise. and if THAT fails i might think about finding another source for some brushes.
after all...with the quality of aftermarket parts these days being what they are....
