Detroit 6-71
 

I bought this generator in auction for $300 plus BP:

http://goo.gl/QuWrwy

It is an old 250 kVa emergency generator with 886 hours. Located
inside a GE facility in Chicago.

It has an engine that looks like Detroit 6-71 with a turbo.

I have always been kind of a sucker for those detroits (first made in
1938). Once bought, tested and resold a 3-53 and loved it. Could not
pass up a chance to buy the whole generator for $300.

Anyway, in my own mind, I would make more money if I separate this
generator and sell the Detroit separate as a running low hours engine,
and sell the generating end to be used with some other engine.

My own reasoning is that very few people would want this as a
generator, because it is really noisy and not fuel efficient and leaks
oil (they all do).

A 250 kVa generator is too big for a typical house or farm and would
only be usable for special needs, and usually companies with big money
would rather buy a $100,000 new generator that is EPA compliant, than
some old generator for $10,000.

Whereas, I am thinking, there is a million uses for a good condition
6-71 diesel engine, like old tractors, landing crafts, or who knows what.

Makes sense? Separate or not?

What kind of engine would it take to provide 20kW from that genset?
If it's small, perhaps the separation would be a good idea.

I've worked on a LOT of 6V51s and 12V71s in 'Nam.

They're real workhorse engines. Even today, some modern custom-built
tour busses and other vehicles of their ilk carry the same motors.

YOu may find the blower bad (at least its bearings), but you'll almost
certainly find a home for the motor. Probably much more likely to than
if sold as part of the genset.

One question, though... 'turbocharger' or 'supercharger'? Most of the
older ones came stock with top-mounted mechanically-driven blowers
(superchargers). Being a 2-stroke, pressure-aspirated motor, I'm not
sure it would even start without at least a supercharger, even if it had
a turbo, as well.

Right. They are awesome if you do not mind the noise, some lesser fuel
efficiency, but like simplicity and reliability.

OK, so we agree.

Lloyd, it has a green roots blower on the side, you can see it. It
ALSO has a turbo on top (you can also see it). You can press the

You can use any kind of engine, but it probably needs the correct
connector plate for the generator end, I will see once I separate
them.

Ok... I see it now. It just looked like "background" until I magnified
the picture.

Yes, with both a blower and the turbo, it should be a good motor, and
relatively efficient -- but still check out those bearings in the turbo
(unless you find a customer who already knows and doesn't care).

We ran them in boats with only the blowers, and they were still dynamite
motors with lots of long-term reliability.

No wonder custom-builders still seek them out and refurbish them to "like

Personally...Id try to sell the entire unit for at least 6 months.
Post the ad and photos on everything from survival mags to city
services and school districts. Have a Detroit authorized guy come in
and give it a good survey and post the results or a link..so there is
no question about its condition.

Post it on HOA websites as well. It could easily run a gated
community nicely. Probably 150 homes. Thats a quarter megawatt...so
she isnt small.

The 6-71 is 238 hp and an inline engine.

Check around and see what they are going for once they are seperated.

Once you pull the engine..that genset becomes..."scrap". Fact of
life. No one is going to stick another engine on it. So keep her
together for as long as you can.

So, you're saying that 2.5x that would take TWELVE TIMES the HP?

I do not know how I can check those bearings, as they are inside the
turbo.

motors with lots of long-term reliability.

They are very lovely and very MANLY motors with a bad ass sound. They
have that general BAD ASS attitude and that's why people love
them. Plus a lot of power for weight and generally reliable if not
pushed too hard.

No wonder custom-builders still seek them out and refurbish them to

I think that at this point in time, the market for them is entirely
driven by nostalgia, not by money making or convenience

I love those motors too.

Here's the 3-53 that I sold four years ago (or so). All pictures were
taken with the motor running.

I bought that one for $200, forgot what I sold it for.

It is a "NOVOPRESS", a modular pressing and cutting system, I think of

There's nothing you can do to hurt them except not keep them full of
clean oil and filters, and never, ever, ever over-tach them. Other than
that, they're bullet-proof. You _cannot_ 'overtorque' them unless you

I see a 6-71, with marine transmission, listed on E-Bay and

has a 4-53 listed for $11,200 outright sale and $7,200 with core. The
same company has "overhaul kits" for the 71 series for from $1,000 -
$3,000.

There is apparently a demand for the engines.

Would this pass emissions tests?

Think about this.

Let's say that you install this engine into a bus or medium truck. You
would get, say, 8 MPG.

With a newer, more efficient, engine you would get 9 MPG.

This means that if you drive 60 miles in one hour, you would pay for
about one extra gallon of fuel. Say $3 per hour.

If you drive 10 hours per day, you would spend $30 extra per day on
fuel.

If you drive 250 days per year, you would spend $7,500 extra on fuel.

Over the expected lifetime of 500,000 miles, you would burn 56,944
more gallons of fuel with the Detroit as opposed to a new engine,
which is equivalent to, say, $170,000 dollars in additional costs.

Pretty close, if you're supplying a combination of resistive and non-

Yeeessss... you didn't read another word of what I wrote, except "pretty
close".

Power factor has to do with voltage vs. current phase relationships.

With purely resistive loads, its 1.000. With most 'common' inductive
loads (motors, not loaded exactly optimally), it can be as bad as 0.6.
BUT... it depends entirely on the load's individual characteristics. And
two inductive loads of about the same power factor, and out of rotational
phase enough to present each's peak current at the OTHER's peak voltage
end up 'looking like' a 1.0 power factor. Given enough of them, randomly
chosen and non-syncronized, they collectively approach a power factor of
1.

Since "residential loads" (as you expressed in your first comment of how
many homes could be supplied by this) are a mixture of many, many purely
resistive loads and a few totally non-syncronized inductive loads...
You'd realize _about_ 250KW worth of energy from a 250KVA genset.

LLoyd

Detroit 6-71
 

But Gunner, let me add just one more thing you apparently ignored.

Say, for grins, that the power factor WAS 0.8 (about normal for ONE motor,
inadequately loaded).

Then the 250KVA generator would be providing a 'useful' supply of 200KW.

That's still a HEAP more than 20 !!

end up 'looking like' a 1.0 power factor. Given enough of them, randomly
chosen and non-syncronized, they collectively approach a power factor of
1.

Since "residential loads" (as you expressed in your first comment of how
many homes could be supplied by this) are a mixture of many, many purely
resistive loads and a few totally non-syncronized inductive loads...
You'd realize _about_ 250KW worth of energy from a 250KVA genset.

So they are pulling a quarter megawatt from a boat engine?

That's still a HEAP more than 20 !!

I didnt say 20. Granted..I just woke up from a long nap before sitting

It has an engine that looks like Detroit 6-71 with a turbo.

I have always been kind of a sucker for those detroits (first made in
1938). Once bought, tested and resold a 3-53 and loved it. Could not
pass up a chance to buy the whole generator for $300.

No ****, Sherlock. Congrats, and YOU SUCK!

Thanks... Kind of excited... Picking up wednesday...

Have fun!


Anyway, in my own mind, I would make more money if I separate this
generator and sell the Detroit separate as a running low hours engine,
and sell the generating end to be used with some other engine.

My own reasoning is that very few people would want this as a
generator, because it is really noisy and not fuel efficient and leaks
oil (they all do).

The mayor of a small burg should have bought that for the times ahead.
Perfect for running an entire small town, huh?


What kind of engine would it take to provide 20kW from that genset?
If it's small, perhaps the separation would be a good idea.

You can use any kind of engine, but it probably needs the correct
connector plate for the generator end, I will see once I separate
them.

I'm wondering what horsepower it would take to make it produce very
lightly, like 20% of its nominal output. Knowing what CAN be mated to
it might help you sell it.

I recognize the words at least. Kraft = strength, power or force (but

Does the Master heat gun go with it?

A 250 kVa generator is too big for a typical house or farm and would
only be usable for special needs, and usually companies with big money
would rather buy a $100,000 new generator that is EPA compliant, than
some old generator for $10,000.

Whereas, I am thinking, there is a million uses for a good condition
6-71 diesel engine, like old tractors, landing crafts, or who knows what.

Minimum 200 hp. Something like say.. a Detroit 6-71

Lloyd, you evidently missed my input there. I'm the one asking how
many horsies it would take to power that head to 20kW, for a normal
handy homeowner's use, so Ig could plug it as a bonus.

Gack..sorry..read that wrong. 20kw is a long...long way from 250kw


It is 250 kVa

Which figures out to 200kW at a .8 power factor.

Oh, that probably makes in a 6-71NT, which is actually quieter than the
original 6-71 with the straight-lobed rotors. Most of the turbocharged
engines also have the helical-lobe rotors, which makes them (marginally)
quieter.

They had one of the original gen sets at work for emergencies when the
underground cables popped (they used to do that a LOT). They'd park it in
the parking lot and run a festoon of 230 V cable to the basement of the
building and wire it into the panel. You'd drive past it and think your car
was going to EXPLODE from the vibration! That was a 6-71 (no N, no T) with
essentially a spark arrestor on the exhaust, not really any sort of muffler.
Everything on your car would be vibrating in tune with the Diesel's sonic

You can run it to produce 20 kW, but you would likely need an adaptor
plate made, as the 20 kW engine would not have as big adaptor plate as
the 200 kW engine.

A muffler does help, with exhaust sound, but not with the rattle and such.
