Might be the answer for Chomper.

So i`ve had a bad ich to own a Detroit diesel and i need power for chompers big motor.
It`s $1500 but i`d only consider it at 1000.
Trouble is i know eff all about detroits and generators, it they both worked it would be sweet tho.

[fatfillup]

That would be cool and I bet could be made to work well but likely will need attention because of its age. 

[slip knot]

Just belt up the DD straight to old Chomper, No need for a generator or lectric motor.

Thats a pretty cheap Detroit if it starts and runs. The genny is 3 phase so its going to have limited appeal to most. Looks to be an Onan by the color so it may be able to be mult tapped for other voltages but at a lessor rating. The DD is still fully supported with all parts still available. Keep it full of oil and enough fuel and it will run forever. But feeding it oil and fuel will be a full time hobby.

[Rural53]

Do eeet.



Not that we are enablers or anything

[jabberwoki]

So it`s 25 KW .
2 questions. Can it be adapted for single phase output and is 25KW enough to keep a house humming if the power goes out?

[fatfillup]

25kw should run your house well

As to can it make single phase, it might but you can always run a transformer.  Course that could be costly for a big one

[slip knot]

Yes and maybe. 

25KW is more than enough to run a house. BUT you may not be able to get a full 25kw out of it if your not running 3p. Depending on how its wired. Some generators came as reconnectable for different voltages and some came as 3P 480v only. You would need to get the mod and serial # off the set to find out for sure. There are a couple of guys over on Smokstak.com that are pretty sharp on those old Onans and can probably direct you on what you have. if you can get the data plate info. 

Theres even a few guys over there that are damned sharp on the DD.

I got a clutch set up for it ifn you want to just belt it up to Chompy and bypass all that lectric nonsense.

[jabberwoki]

Tempting on the clutch but even the 1-71 is too big to mount on Chompers frame.
It is a duel voltage set but the guys no to helpful on more info ill see if he can snap i pic of the gen label.

Well i let the add expire and waited a  while then contacted him to see if it was still for sale.
He replied that it was and to make an offer so i hit him at 800.
This is the reply.
That is a little low,as it is in very good shape. hardly run since new. Was used only for a greenhouse backup,but never put into service except to test the system once a year. this is according to the people at the greenhouse,but 800.00 would o.k.

Sooo we`ll see what happens as it`s in Portland.

[gtermini]

There you go!

[slip knot]

Whatcha waiting on?

[jabberwoki]

Just working out details but i don`t count my fish till they're in the basket. A lot can happen till the weekend.

[jabberwoki]

Well his wife just called me sounds like they`re very old.

Anyhow they`ve had in stored in a shed for 10 years and they never ran it.

I`ve asked for more pixs so we`ll see.

[jabberwoki]

Here`s the gen set label.

[walrus]

Is that 87 amps at 208v, that thing is a beast if so. I can't see RPM but I assume 1800. Going to suck down some fuel.

[slip knot]

Well theres a 208 voltage a 240 and a 480voltage so it appears to be multi tapped. Does look like an 1800rpm unit. I think they had a 1200 rpm unit as well but you cant special order these things on marketplace. if that unit was on the Hurricane coast it would fetch 2-3X the $$. 75amps at 240 volts would run the essentials in most modern homes.

$800 for a power plant and Detroit Diesel fix seems like a bargain to me

If you later decide you dont want it I will give you your money back on delivery to Texas

[jabberwoki]

Do you recognize the gen end maker?

[slip knot]

Do you recognize the gen end maker?

I cant make it out but would expect it to be a good unit with the DD coupled up to it.

[jabberwoki]

Is is single phase adaptable?

 The blokes on the generator section of smokestac have identified it as a Lima

[slip knot]

Jabber, my 3P to 1P is way rusty. But I seem to recall if it has multi voltage it SHOULD be convertible to single.
From what I can recall there were 2 configurations of 3P, Delta and Wye. one could be cut up and used for many different voltages and one was 3P only. been a lot of years since I needed to do anything other than replace existing 3P parts.
Ask that question on the stak, those guys are way smarter than me on this stuff.

[jabberwoki]

Righto Capt...ta.

[walrus]

 a wye is simple, any 2 wires gives you 208, single wire gives you 120. 208 will run most 240v single phase motors. Some motors are rated for both.

Never deal with delta but my understanding is you can have a high leg on Delta, much magic smoke has been extracted with a high leg delta system and not knowing it.

[jabberwoki]

So do i get it or not?
If it`s only usable for 3 phase it`s really just a heavy one trick pony that i really don't need.
 If i could power my house that would make it kind of worth while but at 2000lb it`s a bit of a pig to move.
Then there`s the 1800 rpm, wonder if that could be lowered to 1200 rpm?

[fatfillup]

I would bet voltage is proportional to rpm so likely can't reduce rpm and maintain voltage

[slip knot]

 RPM is fixed to the genset. a set of poles must operate at a certain speed to achieve 60Hz. A little deeper than that but thats the gist. You set the speed to achieve a certain no load Hz usually 62ish. then load it up pretty heavy and it shouldn't droop much lower than 58 ish.

Jabber, if it was me it would already be at my place. A small 2 wheel trailer will solve that portablity issue.

[jabberwoki]

Ok .
