Well I think it's time I poke my head back in here after being silent for quite some time. To update those that remember me, I got my 6/1 up and running around a year ago, and after a few teething problems in the beginning, it has worked daily without a hitch, logging several hundred hours. However the generator head has started to howl on me, and I think it may be the bearings.
So I ask, what size are the bearings in my ST 5 generator head?
