Generator - Can you Identify?

[M813rc]

I bought an S-788 shelter from a junk dealer. In the front tunnel was some sort of machine, completely enveloped in nasty rotted insulation, which he said was a pump because it has a hose fitting on it. I didn't care what it was, I just wanted the shelter and it was super cheap.

On getting it home, I pulled about 60 pounds of deteriorated insulation out of the tunnel, found and removed the bent grounding rod that was jamming the trolley, and was able to slide the "pump" out.
It is a generator!
The hose fitting is apparently so you can run the exhaust away from the shelter.

So, everything I read says the S-788's should have a 3-cylinder M903(A/B/C) in the tunnel.
This thing is a 2-cyl Onan, and there are no data plates anywhere on it.

I am at a loss to figure out what it is. I've searched SS, the web, and RTFM (many of them), but ......

From the pictures, can any of you wonderful generator-savvy folks tell me what it is??

Thanks, and cheers

Can you please step back a few paces and take a few more pictures? I know someone who might be able to tell you much more about this beast.

Certainly! I was trying to get as much detail as possible in the pictures, since the site makes them so little.

You do know that the photos in your post will enlarge if you click on them, right?

Interesting, do you see a data plate on the side of the generator head? It would be on the side where the oil filter is located on the motor. It can't be mush more than a 6-7kw because the 2 cylinder won't be able to handle much more. I bet it doesn't have many hours on it, the oil filter is still painted green from beginning new or rebuilt.

I don't have any identification information for you but I love those little generators.

We ran one for an entire year straight. Shutdown once a week for pmcs then started right back up.

They are good little gen sets when working right. Pretty much the same for anything anywhere in the military.

OK, I am going to ask someone I know if he will take a look. Then if I can copy the pictures, see if I can send them to him.

Well, yes..... I don't know the identity of the generator, but I'm not a bloody moron....

with my 4k monitor the pictures are still only about 3" when clicked on

From the initial pics, looks like you got a MEP-802A genset. See if the Genhead has this data plate on it.

Also too, looks like you also might possibly have a Tier 2 reset genset. In a T2 reset,if the engine is bad or has been gone through, the people/shop that has done it will usually paint over the installed oil filters. And from your pics,you've got one. I'm not sure on the oil filter service interval for the 802A, but i can confidently say that your genset should only have between 1-250 Hrs on it.

I didn't meant to insult you, but I also didn't think the enlarged photos were that terribly small. I readily admit I've overlooked a few seemingly obvious things in my life.

I think kavesman1 might have a winner!

[M813rc]

Agreed! MEP-802A it is. I haven't seen one in that state of undress before.

Kavesman, thank you. No data plate (frustratingly, none anywhere, on generator or shelter). But I now have no doubt you are correct on the ID. And the number of hours - it shows 100.8 on the Hobbs.

Triple Jim - no insult taken. My retort was typed with a grin, which didn't translate onto the page.

Gimpyrobb - playfully poke yourself in the eye for me...

Cheers

It's clearly a LPW2 engine. The question is what gen head is attached. A 802, or a 812 head? Or something else? And where are the rest of the relays and controls?

 

[Guyfang]

Folks, this is not a MEP-802 or 812. It is a LPW2 engine, and might have the same head as a 802 or 812, but there the similarities stop.

Controls will be inside the shelter.

Curiosity got me looking through some of the info on this shelter but the literature just says generation as supplied by user so it doesn't specify a particular generator.

They have a 248 page TM on the shelter here under the related media tab. http://www.gichner.us/s-788.html

 

[M813rc]

As stated above, all the controls are inside the shelter. Batteries and fuel tank are on the trailer (or, if the shelter was mounted in a Humvee, it would tap both from the vehicle).

From what I have reviewed in the manuals, the head is the MEP-802A. The LPW2 engine appears to be the same as that called the DN2M by the military, and that is what powers the MEP-802A generator.

Educate me, please - if this is the engine that powers the MEP-802A and it is attached to a MEP-802A generator head, why would we not call the complete unit MEP-802A?

It appears that most everything I need to maintain this generator is in the MEP-802A manuals and TM-9-2815-252-24, which covers the engine.

Cheers
