A friend called me and asked if I wanted a military surplus gen set. I
figured sure why not, even if it did not run it has scrap alumimnum so
I went and picked it up. It turned out his dad drives truck, and had
haualed a load of Armored personel carriers to some bombing range out
west to be used for targets, and they had these gen sets on some of
the APC's and he scrounged one and brought it back.....but its 28VDC
output so it was no good for his anticipated use.....so out it went.
Its powered by a 4 cylinder air cooled opposed gas engine, (made by OMC) It has some pretty high output.150 amps, 4.2KVA @ 28 VDC two wire.


So I get it bring it home and fire it up. Real pain using a rope
start to crank it over, as I did not have a battery or enbough jumper
cables to cobble up 2, 12 volts for a battery. ANyway it started after
about 5 pulls, and I let it warm up.............Started flipping some
switches etc and generator cam on line, and sounded good. The motor
smoked a bit initially, but it soon cleared up when I put in fresh
gas.......No knocks and it sounded great....I figured I would run it
for a hour or so and then drain the oil and refill it with fresh
oil.....and ponder what I can do with this thing. Oil was checked
before I fired it up and it was fine.....tach showed it running at
3600 rpm, which is what it showed it to run at, and about 45 minutes
into its run, it made a loud knock and bang and stopped. Its froze up
solid. Gauge showed oil pressure to be in the green.......so I don;t
have a clue what happened other than the motor blew. I disconnected
the generator from it, hoing it was the generator that screwed up but
no it had to be the *** motor. I had thought about using this motor to
run a bandsaw woodmill I have been thinking about making.........but
now that kills that idea....Guess its strip it down and melt the
aluminum parts, and salvage what may be useable on the balance of the
unit. What can I do with this generator........has to have some use
for something.........so give me some clues!

I had thought it may have had pickling oil in it, but it was oil, so I am totally at a loss as to why this engine blew......probably just one of those things! I just know it would have made one fine powerplant for my future bandsaw mill. :banghead3 :banghead3 :banghead3

Could you convert the generator portion to run from a PTO shaft? Then you'd have power then next time a hurricane blows onshore.

I'm good as far as having power in emergency situations as I have two generator sets. This generator only put out 28 volts DC power........so it was not much use for anything I needed it for. It was the engine IO wanted, once I found out it was a DC gen set.

That DC generator with its output would make one heck of a DC welder, if anyone is interested......just take a power source to drive it, and a rheostat and a few other odds and ends..........

Maybe I'll turn it into a fish shocker! :trink40:

Could always modify it and make an emergency DC lighting system for areas not covered by your reg gen sets. Some guys here get Metro Bus batteries that are changed by date, not condition (our tax $ at work) and that could be a good charger for them? Where's Kevin??? ROF

I'm here....

What I would do is part out the engine on E-bay...

The generator not worth the time to work on it...
If it was AC you could have used a step-up transformer...

Seems that 150 amp would be enough to weld with. PTO power and use it as a portable welder.
