Onan generator removal from 270?

Unread postby Dodgy71 on Wed Mar 16, 2016 11:43 am

Have any of you removed the original Onan from a 270? If so, how did you do it?
I'm not sure that I need to remove mine, but thought that it might be easier to check for any needed repairs. Mine is original and has not been run for 35 years (and I haven't tried to run it yet). At first glance, it looks like a very heavy PITA, so thought I'd ask first...
To be clear, if the gen will run reliably, I would want to put it back in, if removed.

What year is your 270? Nessie's Onan is a power drawer but she is a 76. It slides out for maintenance

Mine is a 1971 270. Doesn't appear to be on a drawer.
Looks like this (sorry not zoomed out very far). Also, sorry, can't seem to keep the pic from being upside down.

EEeewww...sorry... got a little dizzy looking at the genset upside down...My 74 has the same unit but the band cover is missing. It looks like a 6000w cck onan. The gen IS the starter until the unit fires then it becomes the generator. Make sure the fuel pump is working and have a good battery... I think it's easier in rather than out to service unless the motor is blown. Make sure the gen cable is plugged into the rv power outlet. Give it a whirl. I beat my brains out until I plugged in the RV cable and got my lights. If pulled and money isnt too much of a prob, I would goto a honda portable, lighter, more efficient and you can move all over and place in the original spot to run the ac while going down the hi-way... JMO..
BTW, there are loads of manuals on/in this site including your model genset...and no oil filter & uses non-detergent oil.

BBB,
Have you had any troubles with the E10 gas in your generator (I'm assuming you still have your Onan)?
I love the Honda idea, but if I can get this Onan to work, I'll have that much more dough to spend on something else for the Travco :mrgreen:

As I am clueless as to the ethanol? content of the gas I
buy... my main schtick is cheap gas... It is usually 87
octane with other octanes sometimes higher dependent
upon pricing...engine runs fine... as does the genset.
The only caveat I can think of is higher consumption due to
less efficient or lower octane?... Don't really care as 8 mpg is enough
and higher is gooder... If the close fuel consumption is needed I have
it and will dig those figures up if you want and will help you
FWIW

Yes... mine is a 6KW CCK Onan

Thanks BBB. I'm not worried about consumption or efficiency, just functionality and maintenance.
Also, I posted a separate E10 topic for generators.

My 1977 model 270 does not have a slide out genset. Sure wish it did... would make changing the points easier.

Maybe the slide out set up was only for the Mahal? I do love having it. Makes oil changes and other service a breeze.

Me thinks the slideout was optional IF you wanted to pay for that convenience....
My 1976 270 2+2 Mahal had NO slideout.....BUT it did have a screen door!
I can change my oil without any problem. Same for the air filter and this model
has no oil filter. Run it until warm, then drain. Refill with non-detergent/straight
oil. I havent had to set the points yet @ 1000+ hours... fires & runs just fine...
besides, with a 100 gallon gas tank..who cares about efficency, i sure don't...
