- Designed for those who maintained ship and submarine power plants, this WWII era black & white training film is about the lubrication system. Copyright 1943. The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations. The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938. The first number in the model series designation refers to the number of cylinders, and the second - 71 - the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). Inline models included one, two, three, four and six cylinders, and the V-types six, eight, 12, 16 and 24 cylinders.
The two largest V units used multiple cylinder heads per bank to keep the head size and weight to manageable proportions, the V-16 using four heads from the four-cylinder inline model and the V-24 using four heads from the inline six-cylinder model. This feature also assisted in keeping down the overall cost of these large engines by maintaining parts commonality with the smaller models.

In 2023 I have soviet copy DDS 4-71 with new russian name ЯАЗ-204 and I use that amazing video for understanding lubrication system my engine.
Thanks a lot for PERISCOPE FILM!!👍❤️
Thanks, Periscope! Been around these old screaming 2-cycles all my life! Thanks again!
One of the best channels on TH-cam
It's 2021 and I have just learnt a great deal from this film, 78 years on.
Many Thanks.
Superb explanation and great schematics/animation to help visualise everything.
Detroit diesels we’re ahead of their time. Exceptionally designed and a great sound!
Oil on ground or bilge and deaf from these...
At least I can't hear my wife scream at me anymore.. thanks GM
I suspect YT suggested this to me because I've been watching Bus Grease Monkey work on these in old Greyhound buses.
And I would guess Scott saw this film before Periscope digitized it and published on their TH-cam channel.
Run one of these almost daily in a old Michigan loader, very interesting thank you for posting.
Me too! It’s a 1960 Michigan 35-A with the 3-53. I wear earplugs - naturally. Still feel and hear the noise. Good times.
@@localcrew ours is a 55a, don't know the year, 4-53, rear steer.
Oh how I love the 6/71 .....
Thanks for sharing! I love films like this!
Exotic engineering for that time, imagine the first people that heard those things screaming
Marine version by Gray Marine. Water jacket on the exhaust manifold, and fresh water header tank shape would indicate this. The oil cooler is beneath the header tank at the front of the cylinder block. Fresh water cooler is also at the front of the engine. Most likely coupled to a Twin Disc marine reversing gearbox 3:1 reduction.
Excellent video 👍👍👍👍
Makes me miss the old detroits on the farm old screamin demon detroits
The enemy submarine wouldn't have to use sonar to find that thing. Between the noise and oil leaks it would be an easy target to find.
I’d wager that these would be so loud it would overwhelm any passive sonar to the point that no one could figure out where the source is, where it is going or how many of them are there.
@@MrChugwater Agreed.
Every time I listen to one of these, I put myself well back then, because listening to the way they speak, it makes 1 wonder, what were the genius is geniuses behind the design of these engines like, what did they speak like? How did they conduct themselves you know. Fascinating!
still many of these in service. I work on generators and I get 2 or 3 a week. always fun to find one that was a reman, and the serial number dates to WWII. sucks to have to write them off to death but most customers would rather replace the generator than have to remove the engine from the skid to do any kind of engine work. wrote off a 16v92t with 590hrs on monday );
Damn ! That's sad news. What an engine !
Been a gen. tech. for a Detroit-MTU distributor for almost 20 years now myself. Used to be owned by Roger Penske before I came along. You can keep the MTUs, I love the old 2-stroke Detroits. Simple and reliable. Hundreds of thousands of them helped our military kick the shit out of our enemies since WWII.
The lubrication system famous for lubricating the ground.
Surprised that the oil filter is bypass and not full-flow. Guess it works though.
I found that interesting as well.
Because the engine operator should keep good maintenance of the engine in specified intervals. (It's a commercial unit) the filter design shouldn't harm the engine due to the oil being changed regularly.
That’s a non-sequitur.
You don’t need oil... Detroit’s like it when you tickle them into the danger zone!
Send this to BusGreaseMonkey!
My, what big bearings you have.
I didn't see any mention of the oil seepage ports included with every 71 series Detroit.
You mean the airbox drains that plug up and cause temporary runaway when idled for long periods? First time that ever happened to me, I dove behind a dumpster, everyone else was looking around for the birds!
My first experience with a Detroit, it was a 6-71, with a million miles on it, straight 5" exhaust, you could drive for miles and still be heard! It was loud, and sounded mean! Seems they could engineer it to be more efficient, abd keep the 2stroke! Adding a turbo keeping the blower, would be awesome, maybe 20-30 psi boost, id like to have one even if it's a tiny 4-53,
They made a DDEC Version
They built turbo Detroits, they have a ‘T’ at the end of their model name. They have to have the blower to scavenge exhaust or they won’t run, and because of their 2-stroke design it’s apparently really hard to build much boost pressure since the exhaust valves are open for part of the intake/compression stroke, but the turbo Detroits do make better power than the ‘normally aspirated’ (blower only) ones. I’d LOVE to have a 6V53T in an old square body GMC Suburban with an Eaton 10-speed and 4WD, rig of my dreams. Nothing sounds as awesome as a 2-stroke Detroit, and I’m not even really a diesel guy.
Great old design just cant my head around why they did piston pin seals like they did
To keep charge air out, and oil out of the air gallery, a failure of one of those caps will cause a run away.
@@michaelladue5655 i understand the need the method seems a bit dodge
@@michaelladue5655 Engines overspeed - the mechanics run away ; )
Its amazing they filter the oil after the oil pump and not before it hit the cooler or mains. Any metal that gets in the oil pan is sent through the system unfiltered yikes. The only reason i can think of is that the oil pressure was too high to filter after the oil pump and not before the oil cooler.
Yeah at 5- 10 psi at idle. Come on man
@@CaptainDayne The oil pump produces 45 to 110 psi at idle, thus why it has a pressure regulator that dumps back to the oil pan if pressure exceeds that amount for any reason.
@@leroygreen1877 yeah not in a 71 series ever screw in a pressire gauge, ever look at on on a boat electrical or mechanical. Good luck getting 10.
Pulling oil thru a filter is asinine!
And actually they have a oil pump gear update to rise pressure about 5 psi.
What oil viscosity does it have???
40
They didn’t mention their innovative ground/engine bay lubrication system.
Yes with a drip pan underneath, piped up to the filler neck and an automatic pump. You could have the very first self filling 71 series.
Innovative stuff there! Im a genius!
@@CaptainDayne They should’ve made like an engine diaper with a vacuum siphon as an accessory, haha! But man, what a joyful noise they made. I want a 6V53T/10-speed in a square body 4WD Suburban so bad I can hardly stand it, and I’m not really even a diesel guy.
@@The_sinner_Jim_Whitney yeah we have a pair of 16v92s in a utility boat. Ran many 12v71 in crewboats sounds great! Nothing like them
@@The_sinner_Jim_Whitney id love to install an 8v71 in a k5 blazer.
@@CaptainDayne Then you better get started on a homemade chassis that looks like a bridge, and plan on sitting in the backseat and having 1200 pounds of ballast behind you, haha!

You can make half a video game characters, just by using names from engine components..
And then the lube oil leaks out all over the floor.
Bet ya JFK watched this in his time?
