Brush gobbler

[Gregory OConnor]

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.
