Generator vibration

[Joyce and Richard Hayden]

Greg,

Remember Doug & Terri at last Q rally more or less in front of you guys? He let the vibration go too long and had to get a new motor. Took out the bearings. They have since sold the coach. Very nice unit - light blue.

See you at Q this Jan.

replacing mounts to 'new stock' as Fred writes may be all you can do.
softer mounts often isnt better. and non stock can prove issues at the
exhaust. I wonder if stock vibration was ever an issue or if your
vibration is a degenerative / failure result? Often vibration is a
sign of a broken mount or a engine idle/run cadence problem. this is a
good place to view the results of members repairs to that prob.

The 94pt powertec has an electric fan. my fan makes more vibration than
the engine. as it starts up I can see that the blades are unbalanced.
the other area of probable vibration is the union to the exhaust. some
setups may have vibration at the coupling of the 'engine to genhead' .
the coupling in many has little variable of alignment and in later
years the engines were fitted with cone shape crank shafts. I have seen
the bolts between the genhead and the engine (LightTowers) snap due to
alignment issues at the genhead/engine union.
Vibration is one of those energies where control of of must consider
newtons "for every action " law.
