- This is my 1-71 that I restored a few years ago. It is a sweet runner and those who know Detroits will appreciate this we beauty. I work for the Detroit Diesel agent in New Zealand so was able to source the parts and info easily to get her to the standard it is now. I have a parts manual for it and a few spare gaskets that were made in the rebuild. Less than 1000 of these were made and I only know of 4 in New Zealand. I need to get a reverse drive tacho for it as you will see it's not going. The serial number is 171-537. According to my info it was made in 1939. I have decided to sell it. It is listed on www.trademe.co.nz.
These little 'mouse' motors are rare as hen's teeth, especially in running condition. They were pretty unique in that they had the heaviest flywheel of the 71 series (almost half the weight of the engine at around 400 lbs.)😮 This one is the 1-71P (power take-off). They also made them with an integrated 10 kw generator (1-71G), and a marine version for small military landing craft (1-71M). The first known production was around 1938 and nobody quite knows when the last one was built, but it was somewhere around 1940. Records show that there were less than 1000 of these built and only 79 or 80 running survivors world-wide. The only engine that Detroit built that was more rare than the 1-71, was a short pre-production run of the 12V-53 that was slated for military personnel carriers and small tanks. Reportedly there were only 25 of these built, and 4 or 5 known to be running today.😉
Speaking of rare engines. Detroit Diesel/ GMC built a small gasoline powered single cylinder generator set model A41-1 used for military vehicles during the Korean War. I own an Army tech manual for it. I have yet to find ANYTHING else on this elusive monster much less any photos or videos of one either static or running. I sense they were a severely limited run and most of not all got scrapped with the vehicles they powered. But it appears according to this repair manual to borrow alot of the components and designs from the 1-71 diesel engine.
@@InflatablePlane Very interesting! I'm sure there's probably a lot of one-off experimental engines that got shelved before they got 40 or 50 produced.😉👍
@@InflatablePlane wasn't there a video , South Pacific Islands, a guy rescued a rusted, crusted, hunk out of the sand, near a bay, or beach.
He had to replace some aluminum pieces, heavily corroded, almost non existent...lol
Likely a different engine, though an interesting video to watch.😎☕
In a word, WOW! I have never seen a single cylinder Detroit before.
Me neither I have looked on youtyube for a very long time that's nice.
Yes, Wow, Who knew
I have seen them as power sources, but never on vehicles. However the sound is familiar
@Todd Amtmann The largest that i know of was 24 cyl. I dont know of any 32v71s that were ever produced. At least not of any that survive if they did.
@Todd Amtmann It seems like they may have announced it, but given they had the 567, i think that would have made it entirely pointless. I cant find any information about it.
that would make one hell of a log splitter engine
i like it better than my old fart OMC rotary 530 sled rotary 2 stroke, the OMC rotary is a go to church on sunday fart motor.
Even with only one cylinder it is still so clearly the marvelous sound of a Detroit.
Classic, telling the kids to shuuushhh up, over the noise of a 71 GM. Their eardrums are probably bleeding :-)
That would be the only model 71 GM that I never saw or ran as a genset here in Australia. Amazing to see the great grand daddy of the 24V71T. Great restoration.
My omc rotary sled engine makes way more power than this 1-71 and is much lighter and more compact. Kids get yourself an 850 rotax etec or a Sachs 303 wankle or aixro 294 wankle and make much more power. Hell I would rather have a shaky JLO DL 660 hatz 2 stroke crankcase pressure 2 stroke diesel anyday
@@jlo13800 was your engine made in the 40s and not intended as a performance engine?
Just kidding i love detroit 2 strokes, i just got an 8v92 for 2500.
@@jlo13800 sweet!!! Wish I could find one
My omc rotary 2 stroke sled motor make over 48hp, but a detroit 2 cycle was faster response to load, My OMC is slow and lazy. also Nissan made a UD 2 stroke 75 CID per cylinder, the UD6 made as much if not more than an 8v71 because of better fuel injection technology.

Thanks for the comments. Some of the gaskets are the same as a 4-71 like fuel pump, blower, water pump. others I made. The hardest gasket to get right is the head gasket and the outer surrounding gasket which are both under the head. Its important they are both the same thickness when the head is torqued up. I was lucky to have a sample and got Shuk Engineering here in NZ to make it. For the rocker cover gasket I cut down a 4-71 tin rocker cover gasket. Which gaskets in particular are you after?
I like the way you shhh your daughter over the sound of the detroit running. Must be the quietest single cylinder detroit in the world
We got one restored 171 gen set. I thought we were the only ones in the world with one. Will post video soon
What a great engine. Wish I could find one!
That is just about the cutest little roots blower ever! Super neat! I love the 2 stroke Detroit's, just the coolest diesels out there!
OMG it looks like two end plates bolted together 😆
I'm gonna tell my kids, once there was a diesel motor. The called it Detroit Diesel
GM Diesel first.
Lol! Look at that little dinky blower! Love Detroit's. Worked on/rebuilt many 53 and 71 series while in the Navy.
You could do away with blower and seal up the crankcase with a dry sump feed, then use a rotary drum valve for the inlet.
I just got an 8v92 silver for 2500 sweet deal on this 2 stroke
This is yet another Detroit that was a Clevend Diesel design. Don't get me wrong tho, Cleveland diesels ARE cousins of Detroits, and made by GM as are EMD locomotive engines. Funny, too, that in today's "4-stroke diesel" world, the 2 strokers are still the most fuel-efficient, and cleanest-running diesels made! Fairbanks-Morse still makes the opposed-piston diesel and it's one of the most efficient ever built! I say this "4-Strokes SMOKE 'till they BLOW UP!" 2-stroke FOREVER! I have a rare 4-51.
Russia still build opposed piston engines for their old tanks and did for decades. They were big one too.
That's a neat looking paint shaker
The starter motor is larger than the engine...
Lool
Nice !!! sweet sounding Jimmy motor . not many 171 Detriots around @ all .
Never seen one before but I love it
Of the Detroit 71 series engines the elusive was the 1-71 that saw production from 1936 to early 1940 as in late 1940 the 2-71 began production as restoration of an 1-71 would have been challenging as original parts would have been obsolete as reproduction parts would have serious modifications to work.
Depends on the part. Injectors, valves, rocker arms, the two fuel lines under the valve cover, governor (maybe), fuel pump (maybe), pistons, cylinder sleeves, rod bearings, and wrist pin bearings should be the same as any 71 series. Maybe other parts. GM sold these engines on the commonality of many parts within a series.
I just wanna hug that little ole dee-troit diesel!
Just seen this and got to say that's beautiful. High quality job you've done
Sweet running detroit. Love it.
id absolutely love to see a 1/2 ton pick up with this engine hell id buy it
make it a 4x4 if u can
710 e backhoe
Cameron Stoltie or a little quarter ton.
@@tripplefives1402 yeah I was reading up on the 71 series and saw the hp range from 10- over 2000. I had to check out this single cylinder for myself. I love these old gems
@@tripplefives1402 To heck with horsepower that little Detroit is a torque monster!!
wow ...🤔 very impressed... 1 cylinder...that's music to my ears...😌
I love the 10 horsepower rating on the 1-71 engines. Stepping up to a 2-cylinder gets you 68 horsepower!
The 1-71 is actually around 34 hp. and they used them for small generators (10 kw), boats, and with the pto drive you see here.
I have never run across one that small. My smallest was the 3 cyl. Also had a 6 110.
This would be so badass to have as a backup generator for my house
CRAZY! I had no idea that this existed! Rev it to the limiter and make it scream like a 6v71
Detroit diesels are bad ass!
Sweet from Vancouver Canada
Pretty rare engine I think
The lobby of New England Detroit Diesel Allison in Portland, Maine has one of these that used to power the weather station at the summit of Mt Washington, NH. I’m not sure if it’s in running condition, though.
You have to wonder "WHY" they would make a 1 cylinder version??
I think its really cool that a lot of guys are rebuilding these "DETROITS"
If i had to hazard a guess, for powering small things like a generator set or a water pump. That little bugger will have plenty of torque to do the job.
GM had a division called Delco Light who's main business was building little one cylinder gas powered light plants for lighting up farms. This is the same Delco who'd later be famous for its electrical and electronics used on GM vehicles until 1994.
Thank you...
SWEET!!!!!!!!!!!!!!!
you're right that's a sweet sounding engine.
Nice job buddy, sounds really nice!
@leebuck180 they are a detroit part. cheers
So cool 😎
Perfect for a pump or generator
omg its a BABY! Super cool ))
that would be a neat engine to have
The rarest of the rare. Needs a rebuild though.
sounds like my air cooled single cylinder yanmar
Sounds like my wrx, only this is supposed to sound this way
Put 12 of these together, and it would be a 12-71 inline Detroit😁
Not nearly the same torque or H.P., but it would have individual, replaceable cylinders😁
where did you find the allis chalmers tach, because thats another item thats hard to find new.
BOA NOITE! EU NÃO SABIA QUE EXISTIA ESSA VERSÃO DE 1 CILINDRO....AQUI NO BRASIL EU NUNCA VI !
Heard the old One Lung Jimmies are rare engines. What year is yours? I heard they were only made pre war or maybe through the war? Ive only been privileged to have run one Driptroit powered machine, an early 80's pneumatic starter or "huffer cart" used for cranking jet engines. It had an 8V71 under the hood powering a HUGE Roots blower to pump all that air to start a small commercial airliners engines.
That has got to be an easy rack to run...
Damn i want one
You see if I ever had one of these I would have no idea what to do with it... To big for a lawnmower but too small for a truck... To putt putt putt putt or not to putt putt putt putt
Golf cart!
vector6977 one of those John Deere Alligators
very cool... :)
Awsome!! Great job
Do they put these in john deere 650s??? Because i mow with one that sounds similar
Hello, did you ever sell this motor?
What a beauty. Sadly Detroit Diesels were never really a thing here in Germany. Is it true these only make 10hp. I own two 2-stroke diesels half the size that make that much power, so I guess these are really meant to last then.
I've always seen listing of 30-36 hp depending on which model. The generator I think was the lowest power. And the marine version the highest. But I could be wrong.
Since the 2-71 makes 68hp base, a claim of 34hp seems to make sense for the 1-71.
Recommend max rpm was 1200 so yeah it’s not a lot of HP but tons of torque.
I am rebuilding a 1-71 as well and I was wondering if you still had those gaskets or if you knew of where I could get some, hopefully mine will loom as good as your when its finished
That would be great in a mini excavator. Like 7,000 lbs. Maybe?
what year is that engine built?
Would make a nice small marine engine asawell. :-)
I sure wish I could find a engine like this one for my wood splitter....any idea where I should look.
It’s 875 lbs as it sits, you better have a hell of a frame on you’re log splitter 😂
I am considering buying a 1-71 driven gen set and get it working.
Care to talk me out of doing it?
Can u put a 1-71 in a toyota truck or a ford ranger or a jeep cherokee or a ford explorer?
Or can you put it in a toyota rav4 or a chevy tracker too as well?
lol this engine produces 10 horsepower xD
Aldrick GMC you would want no smaller than a 3-53 or a 3-71 if you want to at least go 60 mph. A 1-71 will barely power a golf cart
You would want a 6v-71, if you can fit it
So it would over power the ford then?
Price??
does Detroit still make 1-71 engine?
60 years ago, they still built these.
What's the gear box?
That's not a gear box that's a clutch housing for the pto engagement & disengagement for what your powering.
@dirtyweezel NZ$7500.00
Hey i have the same dirt bike. drz 125
Please tell us hp
How much do u want?
MINT
lol no. they havent made these things for like 60 years
Now get cars with American engines
Why ? They are junk
