Hello List,

I have a "whirring" noise that developed a few months back.  Changes with the RPM of the engine.

If I was back in the aircooled days, it would definitely be the generator bearings.  It has that classic sound.

So I pull the best and started it briefly...noise gone.  But when I spin the alternator, it doesn't sound that bad.

Could it be a the waterpump?  What kind of a noise do those bushings make?
