I think the shaft is tapered to the engine?? so it then could be the
bearing in the gen or the mounting bolts that hold the gen to the engine?? MikeH pointed out some time ago that it is important to replace critical bolts to get them back to spec torque. I have a coleman light tower that had a crack in the casting that holds the genset bearing. once I welded the crack I then started to run thru brushes . I guess I off centered the bearing seat. when I pulled the genhead off the Kubota I noticed a broken motor mount on the engine side which must have cantilivered stress on the duo and caused the crack. Servicing mounting points may also help with vibration. vibration is more annoying than noise. On the topic of mounting and vibration; BB has some funky exhaust mating systems for genset slides. I notice most vibration come into the coach from the muffler mounting.
