Something to investigate or be concerned about, as there should be a drain?
My old a/c did the same and my new a/c does the same. Don't know if this is good or not.

I'm betting it's your drain pipe.

Yup, we are! I saw that it was cracked in the front corner when I installed the new one. Problem was I had a "helper" that was only interested in finishing it all up. My friend is a general contractor and is to used to slamming it all together to finish the job. I really do appreciate his help but I would prefer to work with someone that "understands" if you know what I mean. We didnt even get the a/c situated right on the drip pan and roof. I have to loosen it up and align it. I'm afraid it will leak come winter. Will wait until October when the heat drops below 105 degrees up in Red Bluff.

Just wondering what the advantage might be to put the GenSet on a slide out will be? Mine is an Onan 4000. Replaced the fuel pump a couple years back. It needs a good tune though. It sure would NEVER pass a Calif smog test!

Well, I thought it was a good Idea....
The plan was to make it easy to service and get at the wiring etc, as well as apply the soundproofing.
If you notice, ther is about 1/2' under it now, so I plan to lean the whole compartment up and put soundproofing around and under too..
It will be interesting to take some more readings when its done!

I'm really interested in the sound/vibration mounts that you end up with. My GenSet seems to vibrated the entire coach!

dadstoy;1041141]Just wondering what the advantage might be to put the GenSet on a slide out will be?
====================================

PO would have loved to of had a slide, bill from 2004 at Cummns shows $351 labor charge which includes dropping genset to facilitate service.
Change filters, sp plug, and starter and an engine clnr 12 oz. total bill $620.

I looked at my setup and it only takes 6 bolts to disconnect from frame but then what do you do with it, it would drop down, giving access but requiring a stand or jack system along with having the MH high enough to have clearances.

Wonderful...
Was getting stuff done... bent to tie my shoe lace, and now my back is all spasmed out... tried to battle thru it, but failed.
Laid up in bed with an ice pack on it.

DaveFL:
I love the idea that Brad had originally. Makes so much sense, for servicing the motor, wires, or compartment.
A motorcycle jack is what I used, they are cheapish and usefull for so many other things, and whilst it was not quite tall enough, a couple of peices of plywood made up the difference.

Dadstoy:
Mine does create some vibration, but its not bad, so maybe you have something else going on with your Onan?

In reality, when inside its pretty acceptable at 63Db , and that WITHOUT any real soundproofing left. My girlfriend said it was pretty quiet inside.

What was interesting was the noise levels were greater FORWARD of the Genset, which tells me that the exhaust system is well muffled, but the sound is escaping from those lower air intake vents.

The Kohler mounts look likes they are just springs, so the whole unit bounces about at times, and must pass some NVH into the chassis, so isolating the genset from the M/H frame more should help.
The plan is to have around an Inch of modern MLV/Foam soundproofing on the inner walls where there was less than 1/2 of just foam before. The compartment floor will get a layer of 1" too, and under the genset there will be at least 1/4" of MLV, and maybe some closed cell foam, where there was nothing before.
The compartment door will get soundproofing too, but I will wait to get advice on what will work and allow air to flow, as the Tech said there is a way to flow air AND block sound transfer..

On the subject of the actual engine; I fully plan to replace the plugs, test the plug wires, replace fuel lines, do a compression and maybe a leakdown test.
The mod I did to the oil pipe will make draining the oil, as I could just unbolt the compartment door, and put a funnel under the plug. Using the Levelers on the oposite side will assure a better drain too!

I want it running quiet and smooth, so will do a whole tuneup.
Also noticed that it "runs on" or diesels sometimes after I stop it. I have had great success with Seafoam, so plan to do that too.

Here are a couple of "Vintage Tools" I have in my Garage to get the ignition and mixture spot on.


Beckman Ignition Analyzer..
Will test everything "older" from 2 to 8 Cylinders, and Rotary motors.
It can also balance test, by killing one cylinder at a time and measuing the power drop...
Used that on a 6 and 8 cylinder motor, but not sure how well it will work on 2!



For the Carb and mixture setup, I have a Beckman Exhaust Analyzer, that tests CO and HC..

Hmm, my Onan has 1300+ hours and is quiet as all get out. Could it be that it's propane-powered, serviced every 100 hrs, and the fact that I excercise it once a month? I run the same Delo as my Isuzu.
