Dick I had the same problem with the sheet metal rubbing the flywheel.
What I did was loosen the all the bolts in the front and move the complete
unit until the rubbing stops. Then tighten them. I used a small hydraulic
jack in different locations under the generator. This is a trail and error
situation. So don't give up. When you remove the front cover from the
flywheel end you notice the frame rails become slighted twisted due to the
weight of the generator. Now if I have to remove the front cover I support
the unit with a board under the oil pan to help it twisting.
The unit doesn't appear to run cooler except I don't have the heat directed
under the coach plus there is less dust when moving over dirt roads. It
will run cleaner.
