Generator vibration - Scott Forman - 06-23-2007 05:05
My generator transfers considerable vibration to the interior. What's
the word on replacing mounts? Where are they available? Are there any
other "tricks"?

Scott,
Our 88 FC has the 8.0K, 3 cylinder Kubota, located in the rear
driver side bay behind the dual tires. I removed the gennie to
service, re-insulate, adjust valves, t-stat. etc. and cleanup this
area. The motor mounts were flat as a pancake, so I replaced them
with three from Onan, They were labeled , vibration dampeners.
The replacements were more robust with more rubber. If I were to do
this again I would go to NAPA and try to match the part, Onan charges
to paint them green.................
I do not know if this really helped with noise or vibration, But ,
replacing the flat, hard mounts made me feel better.

I replaced my mounts with small firestone air bags. They work great, but
the best way to install them is with a regulated, check valve air supply to
keep them at the same pressure all the time.

Do you have a part number or anything?

Not really just figure out how much your generator weighs and size and
type accordingly

Does anyone have any good tricks for reducing vibration from the
Yanmar/Kohler generator?

Hello Scott,
This is a project that is nearing the top of my list. I also have the Yanmar
Kohler set up.
in our 83 FC. I recently completed re-insulating my engine compartment and
installing a
new salon floor. I used products from Soundown a company that specialized in
quieting
down expensive yachts. The have a wide range of products for insulation and
vibration damping. http://www.soundown.com/VD.htm
I am very satisfied with the results attained for the engine and floor. I have
discussed the
generator issue with one of the Soundown reps and he suggested stripping
existing
insulation and applying a peal and stick vibration damping sheet and over that a
2" 2
lb/sf ft insulation. I used 2" fiberglass 2 lb/sf with a lead shield for the
engine
compartment but in the generator compartment I will go with 2' 2lb/sf composite
with
decoupler.
On the sub floor in the salon I used a heavy rubber and foam its also 2 lb/sf
with the
foam side down. This is a great base. Over that I used Dupont engineered
flooring
(Hickory). Looks great and its easy to install. Its a click together product (30
year
warranty) and can be changed out without a big hassle. I would have extended
this sub-
floor through the mid coach and kitchen but, I have a nice tile floor and did
not want to
go over it or tear it out. Thats why my generator sound control will have to be
dealt with
exclusively from below.
I realoze the PH has a whole different set up but I think the principles of
damping
vibration will be similar.
Thanks - NH Bill 1983 FC 35 SB

I have done extensive insulating also, with good results. Vibration
is a different animal though, especially that which is transmitted
through the steering column when driving.
