Blowers, valve covers and badging are sold. Check our eBay listings to see what else is available: www.ebay.ca/usr/deb0ssgarage?_trksid=p2047675.l2559 Corrections on the video: The engines are not ambidextrous, you can't switch the cranks around because the flanges are different. Also when they run backwards, they puke oil out the blowers and it's not good for them. You need to time the engines differently in the timing cover to get them to run backwards.

I have some information on the Mexico head @19:00. I used to work at Detroit Diesel Remanufacturing and they started bringing in new bare castings from Mexico that we would CNC machine into a finished replacement head. The Mexico castings have had problems with QC and consistency of material. This option of head was usually cheaper for the initial re-man cost, but as you can tell with this example, would not usually hold up in the longevity department. These platforms were put on the back-burner of interests for Detroit Diesel at the time (especially for remanufactured replacements) because of the then-new development and marketing of their DD15 engines after the transition out of the series 60.

If you guys care, these are essentially mini versions of prime movers for locomotives made by GM in the US and Canada. 16V-567s(567 CU. in displacement per cylinder) were used in early locomotives like a GP7 through the GP35. The 645 engines were used in EMD GP38, GP40 , All the way through the SD50. Fun fact: An SD45 had 20 cylinders and could produce 3600 HP at 950 rpm. They did not last long because crankshafts kept cracking at the joint. Most had options in 6, 8, 12, 16 and 20 cylinder options. (Edit)Here's an example: kzfaq.info/get/bejne/eNJ_iN2TuNiXink.html

I drove an 80’s Mack that if you backed too hard into a pile of dirt it would stall and spin the engine the opposite way and would run in reverse. It ran like crap and it was weird seeing exhaust coming from the intake. It took me a minute to figure it out the first time it happened because it stopped and started backwards in a second so I didn’t realize it

I worked for a Detroit Diesel distributor back in the 1970s when the 16V71 was used in the oilfields and locomotives. They were amazing engines and the technology that Rich details in this video is just an introduction to all you could do with them. I worked on Series 53, 71 and 92, but didn't get to service the 149s, which were used in huge locomotives and transcontinental cargo ships. Red Adair, who was the oilfield firefighter that John Wayne's character was based on in the movie "The Hellfighters," used Detroit Diesels because they were comparatively light, produced quick torque, and parts were available everywhere in the world.

@danbenson7587 5 ай бұрын

An engineering marvel in it's modular design. Full roller cams. Can run on just about any liquid that burns. The inline version came out in 1938, v configuration in the late 50's. These engines were built like aircraft engines of WW2, way ahead of their time (90 years ago!). The vocational school I went to had a 6-71, my group got to tear down, measure all critical areas and reassemble. Good times, in 1991.

@keithralfs5190 5 жыл бұрын

As a Marine Engineer these 12v71, 12v92 & 12v149 were very popular in offshore supply boats - very powerful & robust - although the unit injectors in the cylinder head leaking fuel into the heads & crankcase & destroying the lube oil - they are easy to maintain as the cylinder/piston can be replaced as a single unit - the ones l ran were turbo charged & superchaged - technically "scavenge ports" - just the noise when running is exciting - they were designed to work hard - they suffered torsional problems when run at high load & low rpm (over torque)

Brings back lots of memories, every piece of logging equipment on Vancouver island had a 2 stroke Detroit in it up till not that long ago. We rebuilt hundreds of these back in the 90’s at the diesel shop I worked at. We had exchange rebuilt 12v71’s sitting on a rack waiting to go in A Hayes HDX off highway logging truck or an 044 Madill yarder. Also the Allison 5960 off highway automatic transmission a great combination. Every time I hear one of these running it brings up lots o memories and emotions. 😢 I miss a lot of the old mechanical engines, Old Cummins 855’s and the KTA 19 as well with the PT fuel systems, most of the younger techs have probably never worked on them. The 2 stroke Detroit’s were fun to tune and set up, a real art to getting it right, still have all my tune up tools. Thanks for sharing this with us!!

There would more than likely be some in better shape. If Deboss says it's not in good shape I believe him! LOL. Thanks!

jeep 4.0 had a little tick, it developed into a high pitched clatter. I decided a piston skirt had broken up and probably scored the bore. It still drove fine( didn't smoke and only clattered on the over run). I carried on driving it then one day it threw the little end through the block. I drove it two more miles home. I opened the bonnet and found most of a piston sitting next to the engine mount on the left hand side. It always amazes me what an engine will put up with and still run.

3:45 If it's stuck at full rack, that is considered a runaway. It will go way beyond 2300 RPM since the governor won't be able to limit fuel delivery. There's a huge difference between "full throttle" and "full rack".

@iwtommo 5 жыл бұрын

It seems the giveaway for when it is a runaway (rather than just revving up beyond the governor) is when the black smoke is pouring out. It cant get any more air in so it goes rich as possible while still making power hence the rolling coal horror show.

These 2-cycle Detroits are legendary. I owned several back in the day: One boat with two 6V53s, running in opposite directions, and a bigger boat with a single 8-71. Say what you will, they were dead-nuts reliable. Climb onto to boat, pour in 2-3 gallons of crankcase oil and start them up. They weren't fast but they never failed. Yes, they leaked a little but back then, I'd never go to sea without that distinctive small of the Detroit exhaust.

Deutz, Stihl, Sachs and Hatz were some badass German 2 stroke diesel. Look up Holder tractors they had 500 or 600 diesels on these. I one saw a hatz 2 stroke diesel on s dirt stomper that hand crank start. It’s had a separate oil tank on the side also. You had to make sure the tank cap was tight or when she goes bouncing you have a mess.

I have seen these engines run for thousand miles with a conn rod cap in the pan if you don't shut it down. positive pressure from the blower keeps the rod on the crank. the cross head piston came apart in your engine and the rod punched out. the piston rings have a line on the face of the wear surface. when the line is gone the rings are done. you don't need to take all that rocker hardware off to remove an injector. just the rack rod, the jumper lines and the two bolts that hold the rocker shaft. the rockers will flip over If the cam is in the right spot. then you can clean the inj tube, install the new injector and flip the rockers back. adj the inj height and the rack and done. always remove the rad cap before removing the injector- pressure in the rad will seep past the inj copper tube and into the cyl. then you need to remove the head to replace the coppers. (they swedge in from the bottom, and you need to cut the new coppers to set the injector depth. inj depth is the distance from the piston to the inj tip so your spray hits the piston cup correctly for max burn. factually yes the engine can roll backwards and fire up, but I assure you the oil pump is also running backwards so engines do not last long with negative oil pressure. left hand engine have a different oil pump. you pulled the piston too early. if you cut one 3/8" bolt to the exact length and put it in the intake ports you can use the crank and rotate the engine to lift the stuck liner out. piston, rod and liner all at once- provided the rings have enough tension to hold the liner as you lift. haven't seen inside one of those for many years. good stuff.

This engine is practically mythical. A friend of mine swore up and down that the end of production was some great government conspiracy. These were great motors for any stationary application but on road was a different matter. I drove a Sceamin' Jimmy V-8 in a farm five ton when I was a kid. The powerband was like 200 rpm wide, making perfect shifting essential. As a sixteen year old, my shifting was far from perfect. The motor screamed like hell all day and burned way more fuel than a Cat diesel.

@MikeMcGrath 5 жыл бұрын

The end of production was the EPA. General Motor Diesel owned the patent for the unit injector. Cat, Cummin's IH all got heavy fines by the EPA for Rigging their engines to pass the emissions test. But polluting miserably during real world use. They sued GMD on the grounds they wouldn't fairly allow them to license the Unit Injector design because that design was the only way to meat emissions (in a four stroke design) and they won. Detroit was forced to license the design to them at a fair price. That gave way to in my opinion the best and most reliable on highway engines of all time. dd60 3406E and N14 and their small brothers.

Whether a crank exists that could handle the middle section, IDK. The cams would be another problem since they're now so long that there's a risk of breaking. The blower in the middle would also need to be driven somehow. The only way to accomplish this is to add a gear set on one of the ends of the center, and this would require yet another section between 2 of the blocks. I'd like to see one run though. Has all the makings of a sub 2000 RPM irrigation pump or maybe a generator. Nat. gas would be viable, but diesel.. not so much.

@@rayg9069 yeah, harmonics are going to start being the major issue with engines that long. Cranks and cams twisting like torsion springs back and forth until they crack or twist, etc. I guess a 2 stroke wouldn't be as bad since there's a firing event every 360 and the pulses are closer, but unless they're overlapping firing orders there's that moment when a "far" piston is on it's fire stroke and twisting that multiple-foot long crank and then.... well, not. Also just hit me that the way this thing is set up you're going to have multiple cylinders firing at exactly the same time, probably why those dead cylinders didn't seem to show up when this one was running earlier, they had others helping with their work.

My senior year in high school 2007-08 I took Industrial Diesel at the local vocational school. One of our first projects was the tear down and reassembly of a Diesel engine. We had several DT466's, a couple of Cummins 855's, a Cat 3406, Detroit series 60, cummins L10, and a few others. The best one in my opinion was a running 8v71. We had to pair off into groups of two for this project and unfortunately my partner was a real jackass. I fully intended to have that engine in the same condition when I was finished as when I started. We had all the service manuals and everything. He unfortunately saw it as a hunk of scrap metal as did my instructor and he went out of his way to destroy it as well as possible upon disassembly. Needless to say it went back together missing parts and badly damaged. It's nice to see a full video of how these 2 stroke diesels work. I always tried to explain it to people but with nothing to show them for reference.

I learned the 53 series Detroit engine way back in the early 80's. Maybe my memory is wrong, but I think those injectors are easy to recondition. You will need a FLAT surface and some lapping compound to resurface the innards. I remember the injector rack on the 53 series having two screws for the adjustment instead of the one screw with a locking nut. Am I remembering that wrong? Those two strokes engine are real workhorses. It's too bad they couldn't get them to run clean enough to get them on the road.

@kedwa30 5 жыл бұрын

It's industry shmear about getting engines to run clean when really they are getting anything too reliable off the road. They are using the whole "greenhouse effect" malarchy to force the population to accept overly complicated disposable engines. You can put on an after burner to reduce any exhaust to pure elements if clean exhaust is the true concern. If you want to improve efficiency then you could run the hot exhaust over a few Stirling engines. To just take their word that it couldn't be done is both naive and obtuse. They have ulterior motives. Compare the increased cost in fuel over ten years to the cost of buying a new engine every ten years to ensure reliability... When your house is on fire, what engine would you want in the fire truck? The one that gets it there... who really cares about how fuel efficient an ambulance is? If a trucker can't deliver a load on time because the engine won't start then he doesn't get paid. Lot's of real world scenarios where reliability is more important than fuel economy. I think this style of engine as part of a hybrid electric vehicle would be both fuel efficient and last much longer than fancy GDI that uses tiny injectors that need to be replaced when they go bad.
