Maybe in addition to selling engine parts you should offer these junk trucks for sale before you trash them I can use this stuff around the farm.

The engineers of the 71 series were geniuses... Those end drives - housings - Cams - Balance Shafts are interchangeable Front To Back, as to allow LH or RH Blower / Exhaust (Back or Front if in a Transverse install) and there are LH/RH rotation parts available.... Truly one of the most versatile engine systems made...

The amazing thing about the Detroit Diesel Series 71 engine {so named because each cylinder had a nominal displacement of 71 cubic inches per cylinder (actually 70.93”)} is that inline 6 cylinder engine aka 6-71 was in continuous production from 1938 until 1995 giving it a production lifespan of 57 years which is unrivaled in the heavy duty Diesel engine market as well as the light duty (passenger car & light truck) diesel or gasoline market. The 6-71 has a production lifespan 8 years longer than the Small Block Chevrolet engine (1954-2003). The series 71 engine was produced in both inline models with One, Two, Three, and Six cylinder and “V”-Type engines (first produced in 1957) with Six, Eight, Twelve, Sixteen, and Twenty-Four Cylinders. The 16V-71 and 24V-71 engines used multiple cylinder heads per bank to keep the cylinder head size and weight to manageable proportions with the 16V-71 using four cylinder heads from the inline 4-71 engine and the 24V-71 using four cylinder heads from the inline 6-71 engine. Additionally the using of multiple cylinder heads from other engines on these two large engines helped keep production cost down and maintain parts commonality. In addition to inline and V style engines the 71 series engine was produced as a “Pancake Engine” with the 6L-71 or 6N-71 that were designed for horizontal mounting for underfloor applications on larger Crown and Gillig school buses and transit buses such as the articulated Crown-Ikarus 286 and the GM-6046 also called a “Twin-Diesel or Duplex-Drive” engine which was two 6-71 engines Siamesed together making a 12-cylinder engine that was used in later model M4-Sherman tanks and small to medium sized boats such as the Higgins Landing craft during World War II as well other marine and off-road uses following the war. The worn and abused 6-71 that our esteemed host tortured tested to its finial demise is without a doubt the most produced heavy duty diesel on the planet today. One thing is undeniably for certain the effect upon modern world history that the “Screaming Jimmy”, “Driptroit”, “Green Leaker”, or simple “Detroit” 57 year production history cannot be under standard. The workhorse that is the 6-71 founds it way basically unchanged into every application possible from on-highway use in busses, and trucks, military equipment, marine, industrial, generators, construction, pumps, farming, and heavy equipment, in which it reliability has proved to be nothing short of legendary. Admittedly by today’s standards the 6-71 and for that matter all of the 2-Stroke Detroit’s are power pigs but when the 6-71 was first introduced it was nothing short of revolutionary. Before the introduction of the 6-71 Diesel engines were very large and heavy and as a result they were mainly limited to stationary engines or marine applications where weight and size were generally of little consequence. However the 6-71 charged all that with its use of 2-stroke engine architecture which gives the engine a power stroke every rotation compared to the 4-stoke engine which allowed the 6-71 to be much smaller than it 4-stoke diesel counterparts in an era when the gasoline engine was king.

“You get what ya get I guess” best way to describe this channel lmao great video

Learned a lot about blower motors and the fuel injector demonstration was awesome, thanks!

LOL... I like this man, tells it like it is, and doesn't hold back. Has a dry sense of humor. I wish there were more like him, the world would be less crazy 😂

This man deserves every subscriber he gets. I love this content, straightforward and to the point, with no cheesy music or intro/outro. Great video as always!

Glad you’re active again!

Lmao I love your savage don't care honesty about everything or nothing , need more people like you in this pathetic time frame we live in. Amen 🍻

Brilliant designed engine. Rugged, durable, all mechanical, well designed, versatile. Everything you could ever want from an industrial Diesel engine originally designed ore ww2. The fact it lived on so long is a testament to its design and durability. No engine has a bigger fan base than a Detroit 2 stroke.

Your videos are awesome. I love how you explain something and then jump to showing us what it looks like once it’s done. No wasted annoying Timelapse…. Just straight to business. Awesome.

This is a great notification to get. Also congrats on 100k subs :)

Cool insight into the Detroit strangeness. Came for the violence stayed for the education lol great video.

All parts within a series were interchangeable, amazing.1 -71 to 8V-71 .We won't see that again.

I for one appreciate all the time and effort it took to disassemble this Detroit and all the other engines to show what happened. That’s a lot of work and time spent filming and editing. Thank you!

I keep expecting him to say "we'll leave the light on for you" 😆

Anther great vid thanks for taking time out of your busy schedule to entertain us diesel freaks and congrats on the 100k mile marker

I look forward to every video you put up man. Learning a lot and thanks for putting them together for us!

Seriously, thanks for your videos to teach us about diesel motors and it looks like they were invented early on and still work great today

Love your videos, you've got a gift for explaining stuff in a way I get. Thanks 👍👍

Back in the day them sob's were in everything screaming all day long. My first experience with one was my second cousin bought his first semi, a fleet star 2000 with a 671 and hauled grain from the field to the twin cities. I was just a kid but thought the dam thing was always on the verge of blowing up.

Thank you for the teardown and commentary! Your videos are always great watching.

You might hate it but it was an amazing engine!

Glad you decided to tear this down, thanks for posting!

Kinda enjoyed that. You went into alot more detail then guys that actually like detroits do.

Thank you for continuing to make these videos. I thoroughly enjoy watching them. Pretty amazing how some of this was actually "engineered" in the 40's and 50's.

Love your videos and demos! Both the demolition and demonstrations!

1930’s technology,still working great. That governor setup is pretty ingenious. I worked on a ton of those, mostly 8v71’s and 8v92’s. In buses.

I was a diesel mechanic for over 30years. The Detroit 6V71, 6I71, 6V53 and 8V53 were built like tanks. I only experience one run away in my life time and it was frightening but yet exciting. I retired in 2017 and I do not miss working on the tractor/trailers.

Great video - love seeing how this old stuff works!

That was very MUCH a fascinating video! ..... LOVE watching these tear-down videos here in the UK 😎 Thank you.

FYI: Your videos are one of three content creators that I give a 👍 to before I even start watching. Thanks for the great content!!

I was hoping this would be uploaded! That video was amazing! Also congrats on 100K subs man!! Keep up the great work!

Thanks for the teardown. We'll probably never see an engine be produced for so long again. They defiantly had their place in their time.

i appreciate You taking the time to share this with us. Thanks and Best Wishes.

I wasn’t aware of the inline 6 two stroke detroits. I only really knew about the “screaming jimmys”. Drove a V6 in some old Prevost coaches. One of these days I gotta find the farm that had an ‘81 Peterbilt cabover in pretty good shape. Had an 8V92T in it. Told me back then he’d take $2000 for it. Would make for a fun project.

Great video!! Honestly lots of detail! I enjoy watching over and over learn something new each time

Excellent video, KT! You're the man!

You make outstanding videos. Love the content looking forward to the next one.

Thanks for breaking that engine down. I love how they sounded .

Love your channel man! The commentary and the content is totally top-notch! Keep up the great work!👍👍😎

Informative as hell and deadpan funny as hell. One of my favorites.

As the safety police commander, I approve of this oil pan removal technique.

I love these tear downs! Those motors are super tough!

You are the best, I’ve been wrenching for 40 years for a living , luv the humor and could not agree more with you.

Always great to watch

I truly enjoyed watching you pull that "ultra rare" Detroit apart. Thank you sir, I hope you have an awesome Thanksgiving!

I just subbed because i enjoyed that autopsy so much. Even after that incredible torture test the bearings still look that good to me is amazing. Those old oil slobbering motors were sure built to last. I never knew the blower pressurized the crankcase the way it did. I never really thought much about it but thats where the intake is so...thanks for the look around, i learned a few things.

over the last 74 + years I been around working many different kinds of race cars. Diesel have not come up ... Yet now they are in your face in all kinds of Racing, pulling, boat, name it they there. Your doing a great job showing what's up

One heavy duty to another, well done for making light of this engine, well done sir. The runaway king ;)

So what you're showing is that a dingle ball hone, set of rods and pistons and she'd cheech right into life again. Impressive

Good to have you back brother

Good to see another video from you thank you

These engines and all their cousins of the 2 cycle version gave always had very good to weight ratio and they are very easy to work on - the bigger versions were a pain in the ass to set the injector rack on because you were actually dealing with 4 racks connected together ... if you weren't careful you could burn down 4 cylinders with a messed up rack setting. The 71 and 53 were dry liner engine and it required some skill to get the proper liner to bore clearence. The 92 series and 149 series were wet liners and much easier to overhaul. The detroits were very popular in marine applications and generator applications - they built the 16-149 up to 1500 kw and would put them in hospital applications that had to be up and at full load in 10 seconds or less ... you could always tell when your Detroit generator got to 1800 rpm - your nose would start to bleed... oh and our host made a little error when he made the remark about the top bearing always showing the most wear. In a 2 cycle engine there is a power stroke every time the piston comes down - so since the piston never has to be dragged down by the crank all the wear is on the bottom bering shell... I worked for the Detroit distributor in Dutch Harbor Alaska back in 1989 and 1990... and learned this - commercial fishermen can wreck an engine in every possible way and a few ways nobody has ever heard of... but on the other hand I have seen the 12-71 powering a generator turning 1200 rpm last 30,000 hours with good maintenance.. go figure.

Always looking forward to your videos, even if its dismantling an old junk engine.

The injector demonstration was pretty cool. Always neat to see the guts of these dinosaurs.

Great to watch you keeping yourself amused and putting on a hell of a show couldn’t stop laughing great one

that was certainly the very best overall inspection we have seen thank you from the UK

Glad to see a new video from ya bud!!!! Take care bro

Great vid, was right there with you. Very enjoyable in a lazy Saturday morning down under.

Them old 2 stroke Detroit's were some TOUGH engines

Love the channel man. Keep them coming!

Keep making golden videos as time allows!!

I skippered a delivery trip on a small coaster that had a V8 71 Series. What a great engine! It purred along without stopping all the way from Gibraltar to Plymouth - 8 days. One of the crew told me it ran away occasionally and one time they'd covered over 20 nautical miles before getting the thing back down again!

It really good to see someone working w safety always in nind

that was fun. amazing the bearings looked as good as they did. thanks for the video always entertaining.

Always great notification to get. And congrats on 100k subs!!! At 5:00 in, that's one way to get your meds.!

Amazing how after that WOT beat down the rod bearings and crank are still good. Thanks for the blower/fuel rack explanation. Cool video as always.

Best vid I saw all week. Thanks

Appreciate the information. Great video. 👍

Being an Old Detroit man,I enjoyed the whole thing!!!

Best video on 671 yet Iv seen, thanks man!

The way, you disassemble/ rebuild / tourcher these diesels on your channel, is extremely satisfying to watch. Thanks for makin it happen

Congratulations for 100k subs!

Very enjoyable and informative video ...keep up the good work

Thanks! It amazes me how much abuse some components can take

Thanks for sharing!! learned a lot about a Detroit engine!!!

I saw the video of that 6-71 running away, so it was awesome to see the teardown. Thanks for all that extra effort that I'm sure you did not need to do :) ... I mean that seriously, not sarcastically.

I enjoy all your videos. Learn a lot. Had two pickup trucks in my life, both diesel. No substitute.

hey man that was very informitive liked the fuel valve spray shot and the inside .the rings were welded to the piston .nice job man!!!i enjoyed it very much thanks!!

Love your videos!

Keep up the great content.

Great just love a Detroit how it work and sound. When motorway where built back in the day company I work had some Terex motor scarpers and most them had Detroit in back engine they sounded great

Great disassembly of that overheated Detroit diesel engine, I thought 2 stroke engines had no valves, so I learned that, that is not always the case. Excellent commentary and explanation what does what on there engines. Keep them video's coming.

No Man don't say that, it was an Excellent Video!! I've always worked in 4-stroke engine, gas and diesel and never seen inside a 2-stroke Detroit, been in Cats and Cummins. We learn something new every day. You'd be a Good Teacher!!

Great work, made me laugh the entire way through... keep'em coming.

Your videos are excellent, keep it up - Joe

Loved the toaster comment..!!! Needed the laugh this morning

Why is is so satisfying to watch an engine teardown? I guess I just like to see how things work inside.

I’d like to see a runoff between a Detroit a cat a Cummins and a Mac. See which one dies first and which one takes the most damage. That should piss off a few people.👍😁😁😁

This is my new favorite channel👍

Another great video! Keep up the Awesome content!!! 👍

@KT3406E I cannot believe the 'good' condition of that engine after what you did to it! These Detroits are seriously well engineered and built! I wish i could get my hands on one here in the UK.

Reminds me of when I went to school for these engines in early 1980, the Navy used to have lots and lots of them. They still use them in some applications.

Dudes dry humor still cracks me up 😂

I enjoyed it. It was cool seeing what parts were toast and which weren't. Looking forward to buying one of those Detroit toasters lo ok

Thanks for taking the time to tear it apart and show us the guts. Worked on plenty of E model Cats, C15’s, N14’s, and ISX’s, but had never seen inside an old 2 stroker. Always loved the sound though….. Hope to see you sooner rather than later.

Amazed that the bearings held fairly well during its life and final abuse.

Favorite videos on KZfaq hands down

Great channel. I dig the flame pattern in the combustion chambers.
