I've seen a few 1-71s in old ships. All were hand started by baring over a large flywheel and had compression releases. They were running 250v DC generators and ran at 1200 rpm. Many smaller ships and tugboats had a 250v DC system that ran everything from lights to refrigerators.
I’ve heard that sound but never saw the engine. Never knew they made a single 71 series. We were on a dock in Louisiana and a really old tug lumbered by real close. I heard the single cylinder running and saw about a 6 inch hose pumping water. The dock foreman said it was a one lung diesel. Remember thinking it would make a great paint mixer from its shaking. That was about 78 or 79. Nice engine you have there! Thanks for making the video.
They can still be sold…just not new. Great engines in a truck if you can do your own mechanic work like I do to offset the added cost of fuel and upkeep with an old mechanical diesel, we have 2 Cummins and an 8v71 Detroit. 318 horsepower and 4-5mpg aren’t anything to write home about but man has it been reliable. I don’t think there’s an engine that can have more wrong with it and still get you home than a Detroit 71 series.
what's even Moore sad is the fact that these things and others like it are still being used in China and India. but we're the ones destroying the planet. go figure.
At 1200rpm one generator racked up 43,000 hours and was still running. You should check the idle speed-even though it sounds neet to be chugging-it still needs to be idling at 500rpm. I remember this at Delaney and Ahlff
Wow what a cool engine. I wonder how fuel efficiency compares to modern diesels. This would make an amazing home backup generator. Thanks for sharing this video. Probably the 3rd or 4th time I've come back to watch it.
2-71 generators are actually out there and are way smoother and better IMO. I'm looking for one now to replace a perfectly good Perkins light plant I have. I want more juice. These things can have different injectors fitted to tune them to the load.
Use marvel mystery oil in fuel helps lubricant everything i have one set up as generator Its been used as backup in family cabin installation 1937 neighbors across lake know were at cabin when we fire it up ... awesome video thanks for posting 👍 😊
I work on this type of engine in High school Diesel mechanics class. We had a 3 cylinder one like this, also a 4&6 cylinder in line and a V6. Wonderful and powerful
Tom, i didn't know these where so rare and few produced. It's sweet *edit* I still know of a GMC 860 cannonball near me & an IH Coe up in Wis i just found.
So the series number was - 71 and the first one or two digits denoted the number of cylinders. In the early 90's a friend of ours was working on a 16 cylinder one, and I believe that was the largest of the series. 🍃This big engine used to drive a pump that pulled grain in and out of ships at the docks, but i think he was only interested in the engine to service, repair and sell as he was a🏵 machinery dealer. What caught my eye - and that is 🍂why I remember these engines - was how the injectors and the injection pump were all one unit worked by the rockers. Also the scavenging and intake of fresh air by the charger unit at the side were good design elements.🛑
Get yourself a single N70 injector and crank the No load high idle up to around 2250 and you could have a 40 horsepower jackhammer 😂. I assume the vibration issue is why they limited these to 1200.
I think Superior made diesel two strokes used on ships also. Looking to expand into the making of it's own diesels, I think WHITE MOTOR CORPORATION bought Superior in the 50's and chang- ed the name to the WHITE DIESEL ENG. div.WMC.
It sounds like it might be governed lower than 1200 rpm? If I had to guess it may be at 900 or something which would make sense for a 60hz generator. Figure that would be about 25 horsepower?
@BobbyTucker 0 seconds ago Sounds about like a John Deere "G" Model, I used to drive one down in Cherry Valley, Arkansas, for my Uncle Bob, he had a Plantation there. This brought back a lot of old memories. Will this run on 'white gas', 'kerosene', and 'diesel' too? I probably won't get a reply but, if there's anyone out there who knows, feel free to answer. Thanks.
I worked at the Australian distributor for Detroit Diesel for nearly 30yrs and in that time I had heard and seen photos of these but never saw one in the flesh. Do these have the same issue with other single cylinder engines where they can start and run backwards?
My mom used to crank a Petter two-cylinder diesel in the 1960s to operate a rice mill. Sometimes it wold rebound with the compression and start backwards. Trinidad & Tobago. West Indies.
Dang, how cool is this?! That GM radiator shell!!! I thought it was starving for fuel until you mentioned the gov was set to 1200. Any idea how much it weighs?
Sounds like it could run much faster, be interesting to know once you get the tach hooked up what it's really turning but I'm guessing that you're maybe at 1000 rpm or so there.
@@extrapilot300s yeah the one in this video is not at 1200 rpm.. It is governed much below that. I was guessing 900 but it is probably even lower than that. Though the one in your link sounds much higher than 1200rpm.. but with no tach I couldnt begin to guess where.
Automotive 71 series from that era often specced to go to 2100 RPM, and even higher for marine applications, but I expect you wouldn't want to go anywhere near that on a single cyl - it'd probably try to walk off somewhere!
You have a good ear for that . The valves and fuel injector needed to be set . we actually did that a couple of days ago and I will post a new video in a day or so .

That is a real treasure!! Would love to see you start it, by hand.
I have to find a crank that fits and then will do a video . Thanks for watching
@@rileydog362 did you find a handcrank, for the 1-71 ?
May need to have one made, 😎☕
@@invisibilianone6288 ,
We used an old steering wheel that was converted to fit the John Deere "G" model, lol.
The classic One Lung Jimmy!! Super rare and special engine right there!!
5:27 BEST PART FOR ME.
Super neat. I LOVE ALL Detroit 2 cycle diesels from this 1-71 all the way to the 20v149. Thanks for sharing
it is shame we do not live in a free country where these engines could still be made and sold

They can still be found and sold by individuals and preserved and restored
No manufacturer would ever want to make any more of these regardless of country.
@@garygolfer3243Yep. Too durable and fixable. There will be a mechanical renaissance hopefully as the US economy and society continues to break down.

this is the GOLDEN AGE of GM - WELL MADE in USA !!!!!!!!!!!

warms my heart to see that old girl running, thanks very much
It has an incredible sound....love it... great video
About 3/4 through I quit looking at the engine and started admiring that cool piece of property!
What a beauty!!! Thanks for sharing this with us.

Absolutely love it ! What a awesome piece.
Thanks for sharing.
Very Cool .. Hearing it run at low speed reminds me of the term "Thumper"..
Thats too cool, thanks for sharing, sounds alot like a hit and miss engine
Only saw one of these in my 20+ year s as a Detroit parts man.
Super cool motor. The cab over is just as cool
Thanks
Very nice job! Looks great, sounds awesome!
She runs so well and sound so nice 😍
HA! That is COOL!! I think that’s the first one I’ve actually heard run.
You have a 471 saludos her in nicaragua we like detroit two stroke is very good for work see

Excellent video! Really cool and clean!
Beautiful!!! Would love to have one myself. Cheers.
Cool! It would be great to add an appropriate muffler to it, so you could actually hear the sound of the engine and not just the pop of the exhaust...
It's a 2 stroke, the sound of the exhaust is half the fun!
Very nice engine, congratulations.
That engine would be good in a small boot
Hook up a generator and use to power house during power outages?
Very nice Tom.:)
hi there bit late but nice engine , john
That’s is something to be treasured
Beautiful!
I've seen one with a P.T.O as well. Rare bird.
Only 12 continuous and 25 max hp? I can't believe the world spun with these things back then
Considering they only run at 1200 RPM and last forever it's pretty fair
They spin for decades

1200 is for generation.
Very interesting.
Sweet motor. I'd like to know how much torque it makes.
Being a 2 stroke it's actually running much slower than the sound would suggest.
Nice engine ... would be even nicer if it would produce some usable electricity.
Thanks for uploading this nice vid, sir.
Very nice
Ha! How about that eh? I enjoy seeing those old stationary single cylinder engines going. But this is the first Detroit diesle I've ever.
Sure looks like an ancestor of what is now known as Detroit Diesel engines.
That would sound awesome pushing my houseboat across the lake.
I have a old rail car generator but man that is so cool would love to find on of these on day .
Did they have a blower for pressurising transfer ports?
Yes it does .
I had no idea. Another rare one is the all aluminum 6-71 on mine sweepers. Then the mining car 6-71 that is almost horizontal
Is that a "C" V-belt for the accessory drive? What a big ol monster lol
Great video! Super informative!
I just got a 2-71 version fired up after 30yrs being below decks of a navy tug
Would have been great as a commercial fish boat engine of its day.
Muy buen video saludos

So, how do you hook up the tach.?
It sounds like it might be governed lower than 1200 rpm? If I had to guess it may be at 900 or something which would make sense for a 60hz generator. Figure that would be about 25 horsepower?
I have this series 71 one cylinder models 1942 parts book. Like new!
Super cool!!!!!
I'm not "picking apart" things on your work but I'm only trying to help you in case it needs attention. The generator belt appears to be loose.
COE and horse trailer git my attention too.
how fast is it running? 500rpm or so? seems pretty slow
I spy a GMC Cannonball in the background! Does that truck have a video story told?
It sounds nothing like a detroit 2 stroke. Interesting.
I guess I'm late to the party. I like that engine, do you still have it? If so do you plan to connect it to a load? That would be interesting. Thanks.
A real jewel. I see why you wanted it.
Wonder if the starters were ‘one size fits all’ for most of the 71 series. That starter looks a bit large for a seemingly small displacement.
I had a 6-71 and it had the same starter on it . GM used what it already had .
Outstanding!!!!!!
A moon rock for sure. How awesome! Do you have plans to hook up a generator or anything else? Too bad I can't give you two thumbs up.
Thanks for that!
very cool

The starter will always start it in the proper direction.

Trinidad & Tobago.
West Indies.
I have been searching for one of these for a couple of months… Not many out there. At least not for sale. Would love to find one.
I am thinking of selling it . Asking $ 12.500 if interested .
@@rileydog362 That would be nice. Purchased a 2-71 about 5 weeks ago. I will ask around and see us some of my crazy off-grid friends are interested.

A lot

@@extrapilot300s yeah that's more like it! That one has the typical GM sound to it.
Most of these are governed at 1200 RPM so they can run a 6 pole generator.

these engines operated at 1200 RPM calls for a continuous duty applications.
The governor is set way too low, your barely getting off idle. It does run nice and is super cool 😎
Early Duramax?
Detroit all the way . No Chevy parts here .
One lucky guy.
SAE 40 straight grade oil preferred. Do not use multigrade like 15w40.
There's another UA-camr out there and it's called the old 2 Stroker UA-cam channel he's in New York and he has one of these
Sweet
Love it
I have a question. Is this beast aspirated or turbocharged?
IT HAS A ROOTS BLOWER
That is the only Detroit I have heard that does not sound like one.
i want this ONE LUNG JIMMY
Wow how much is this worth?
There was a number of them in boats at propulsion engines
Hey! I recognize that truck. Aren't you the Neo-Flasher guy?
Let’s put a turbo on it

You have a good ear for that . The valves and fuel injector needed to be set . we actually did that a couple of days ago and I will post a new video in a day or so .

This is what these engines worked good for. Not trucking.
