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.

Laid here "On Ice" I have time to research...
My Hours meter, I need to find out if its "Spark, 120v, or 12v" to know where the wire should go..

Also, important info on Genset noise levels.
There is a National Park Maximum Noise Level..
National Park Service sound level requirements (60 dB(A) @ 50 ft) for national park use.


Onan quote their newest LPG powered 6500W unit as 67Db(A)@ 10' at half load..

I will have to retest now at 50' but from my earlier test,
I did set my Meter to just show me the peak level too, but I think thas a fair way to test.
With no soundproofing, its 65.5Db at 6' with no load..



And 73Db at about 10' on full load..


And

LOL, my guess is that it was dripping so much oil it was too expensive to run!
BP should have bought it cos it leaked less than some Wells they own..
Some Arab states have offered me millions for the land it is parked on..

Seriously tho, it seems to run ok..

Roof Vents...

When i was last over working on the 345, i had the ladder out to look at the state of my roof, and what needs to be resealed/fixed.
I am planning to paint it white from the roof joints to the end caps to keep the temperatures down, and save me polishing too.
Evertime we have rain, i have a wet floor in the kerbside Bedroom closet, so was looking at the joints and seams above that for clues..
I noticed something on the roof vent that looked suspect, and needed some opinion and advice...

Both roof vents, left and right, have no cap on them...
it just looked like some screen mesh inside, but even that is a mess..
What stops water going inside?

It is suspect, and prolly the cause of most of your leakage. The gasket is actually a rubber boot that fits over the "gas vent" pipe from your grey/black water tanks. The screen is to protect from critters getting down there. Andy has a kit with screen to fix it. Getting the old Vulcum off is a pain, but a chisel and the Dremmel and a clean with solvent will do the trick. I had water in the same place, cured. Use a couple of wire tires to secure the vent screen.

Thanks for that info Mike.
I searched Inland RV's site and found it... Sewer vent pipe is the term you need to find info.
So now I know how it should look, and is it me, but that is a terrible design!
So, any rain either falls down the Vent pipe, or, as the vent pipe is ROUND and the Aluminum cap hole is RECTANGULAR, it falls between the cap and pipe..
I now find there should be 2 drain holes in the cap to let this water out?
See post #19 on this thread...
http://www.airforums.com/forums/f163...s-24437-2.html

Now look at my vent...
If there is drain holes, someone filled them in!

I would not be suprised a lot of guys do the same thing. I used a couple of dull drill bits to clean the Vulkem from the drains. I also used a dab of Parbond on the screws, which may have been stupid. I figure those boots lasted twenty years, so I'll not be replacing them. Someone will curse me, I'm sure.

I am thinking I might add a small curved piece of Aluminum about as big as a playng card, to the top of the vent stack.
If I put it spaced up about 1/2" it will still alow the stack to vent, but will keep direct rain out.
Also it will protect the seal and sealant from UV degradation.
What do you guys think?

Watch out the covers don't become sails and vibrate you out of your mind. Seriously, you'll find the new boot fits very snug over the vent stack. The boot will prolly have to be trimmed to fit the enclosure, I used a matt knife.

Another Newbie who just picked up an '87 345 last Friday, trying to beat Tropical Storm Lee...it was interesting and not really the best day to learn to drive a wingless C-130. Had lots of rain and wind (did any of you know that Airstreams have occasionally leaked) but I did miss the worst of the storm.

PO had told me about the 2 leaks, not necessarily the velocity of them. Top of windshield and top of left rear curved window. It was kinda like driving one my old Healey 3000's...wiping water with one hand and steering with the other.

Thank you all for the opinions, facts, humor, and DYI pics (especially AirRowan). Tremendously helpful, but I ignored most it and bought it anyway. I feel the opposite of Woody Allen who said, "I wouldn't want to be a member of any club who would have me for a member". I may have bought it just to be a member, but the official reason is "Temporary Insanity".

I do have real question that I haven't able to find a thread about. Can I paint the with White Elastromeric roofing coating to keep it cooler and eliminate future leaks. It's probably here somewhere, but I can't find it...Thanks again

Well HELLO and welcome!
Wingless C-130 indeed...
Yes, I just wanted one, and was not afraid of a project, so went for it!
When your feet hit the ground, start yourself a thread and fire away!
Also, post us some pics of your new baby in the Classic Picture thread too!

White roof stories you will find in the trailer exterior restoration section..
A quick search showed this good thread up..

Smartstream - What is most probably leaking is the gasket arround the stack. Inland has these and are not expensive. Take the cap off and the new gasket will tightly fit arround the stack and be held by the stack cover.
