My twin Honda EU3000is Generator Install

[sledhead]

KISS

the 1 1/4" 90 deg. , 45 deg. exhaust pipe from auto parts store and silicone heater hose.
heater hose is 1/4 " past the pipe and is friction fit to the gene so it pulls out with out any adjusting or removal of any thing . I had this set up on my old gene and it worked great for years . there is a exhaust fan above the gene that turns on when the gene starts that removes any convection heat that is in the bay .

easy to fill up and really quiet !

this is the rollers I used lots of $.....   $ 125.00 but they are rated for this

forgot to say the hardest part of the job was using a 2" diamond hole saw through the s. steel side of the coach . 2.5 HOURS and 4 drills as even with gloves they were to hot to use .

Done it before. Lots and lots of cutting oil, patience, and preferably a cool day....after a good nights sleep....and a good meal.....and a massage.....and some yoga.

Lol. Thanks for the tips. Going to work on this since I'm tired of my gennies sitting out on the hitch platform. I do have to ask this, every time I hit a good bump in the road the gennies shut off?? Even when fuel tanks are full to the top. So I know it it's not fuel sloshing. Could it be the oil sloshing and tripping the low oil shutdown? If so, how do I remedy this?

My 1000eu will sometimes shut off if I move it too quickly when it's running.  I always assumed it was the oil level sensor.  It doesn't take much for it to shut down on low oil, even putting it on a slight slope will do it.

[Scott & Heather]

So is there harm in adding a little extra oil to help minimize this?

I've been doing that for years, too.  There is a point where you can add too much oil and things can go wrong.  The 1000eu takes about 1/3 qt of oil, but I usually add 1/2 qt when I do an oil change.  It still shuts off if I move it quickly, though.  The 1000 is splash lubricated, I don't know if the 3000 is pressure or splash, meaning the 1000 has an oil level sensor, versus an oil pressure sensor.

I work on more of the PowerTech 10 kw than any other generator you can bank on the head bearing seizing at around 2000 hrs   

This reminds me I need to change the bearing on my Powertech 8KW.  I just rolled over 1,000 hours this year.  I ordered the bearing a few years ago when I was ordering some other parts.  The stupid thing is you have to lift up the generator head about an inch to replace the bearing.

dave what cfm is your exhaust fan? i am building the gennie slide this next week.

Hopefully since I have the big Marathon alternator head on my 10kw Powertech, the end bearing won't need to be replaced. The end bearing is the only thing on the generator I can't get too-which means pulling the whole thing out. Good Luck, TomC

this is the fan I had laying around so I used it . when parked it is lots but I have not tried it much when driving ( when its hot out )but then again I think there will be lots of air movement when driving as the door is a vent . I did fill in above the gene ceiling with foam , tin foil bubble rap so any heat was not trapped inside and had to exhaust through the vent door

Ahhh Princess Auto, a place of holy pilgrimage. We have the home store here in Winnipeg and it is always a stop when in town.

Scott,

I am real curious as to how cool you can keep those generators in a bay while rolling down the road.

I know I had a hard time keeping my outside unit cool on the Mini-Split and that was with a hole cut in the floor and a hole in the bay door and a 20" fan blowing out the exhaust through the floor. 

I wonder if you can mount heat sinks to them

Make sure you think about airflow and forcing air in and out before you start cutting up

     Another thing to remember that that a plain blade fan will move static air well but if you have any condition that places backpressure or vacuum on the fan, the efficiency of those drops off quickly.  If you need to move air when you either need to make suction to pull air out or to make pressure to push the air, you need a "squirrel cage"/centrifugal fan.  That's another part of the equation, FWIW.

the original design was a pusher fan pulling air through the condenser down through the floor . I did look at doing that with the gene and when driving the negative pressure on the side of the coach would help move air past the gene and out under the coach , but when parked it would be a lot harder to pull hot air down to exhaust out under the coach .
+ the extra noise of the pusher fan I did not want when parked . I have not had enough of a test when driving when it is hot out to see how well it works .
on my split unit a/c the air to cool it comes through the old a/c bay then through the a/c then it is ducted out through a large pusher fan through the floor . I control the speed of the fan with a dimmer switch so when driving I can turn up the speed of the fan , then when parked I slow it down so it is a lot less noisy . this has worked very well for years

so if Scott could do the testing on this I would appreciate the result . just kidding .

as there is a shut down system on the honda,s and as of yet I have had no problems

I do have a good pusher squirrel  cage fan that I could swap out if needed but it is not as quiet

the design of the honda gene,s are excellent for keeping them cool , quiet
