I remember seeing one when I was 8 years old, in 1964. My father was falling the timber for a road construction project, knowing my love for all things mechanical especially crawlers, he took me to see it. I scrambled over it for a while until joy of joys, the driver got me up there with him for 15 mins or so & let me steer & operate the blade, a little anyway. A vivid memory I've fondly retained.
Yes I remember them back many years ago I didn't operate them but I did see the odd one in operation and they were the best of their time. Just like I operated tractor trailers at the railway with White Freightliner tractors with V 12 detroiters and 13 speed transmissions
+canvids1 I ran a White Road Commander cross country for a good many year. It was a 8V92 Detriot with a 13 spd RR. That thing was amazing. You had to becareful running empty on wet roads. It would brake the tires lose on the pavement pulling out from a traffic light. Thanks For watching.
A unique machine for its time with 2 halves and 2 drive lines, that with one crawler forward and the other backwards it could do a 360 degree turn. The other Euclid dozers with 1 engine also had the G.M. I-6 110 engine for more power at that time.Then later the V series of engines came out.
I worked at a Chevrolet dealer in the 70' s and we had a car hauler that parked there and one morning the driver couldn't get it started, came into the shop and I got to help him get it started. We hooked up a jump battery and tried to get it going, used a couple of cans of starting fluid, IT hit just right and let out a big pile of BLACK SMOKE, it just settled down and idled smooth. That motor had probably had about a million miles on it, It was a 6-71 Detroit Diesel ⛽ IT ran on for a lot more years. Then Ryder bought them out & they got some newer trucks 🚒🚑🚛🛻🚚
There is a TC-12 still around here. It is used at a local gravel pit. Only reason it is used is for the heritage coolness factor. But I agree with all you say. It is used alongside 3 year old Cat wheeled loaders. LOL
Pretty clever, like enabling one operator to work two dozers at once. We used those engines on some of the towboats I used to work on, mostly to run generators. They mostly had locomotive engines for motive power.
I've never seen one of these but what a machine, and dispite what amateur people say, the Detroit 6.71 is a fantastic engine. I've been involved with them for 40 years. They take some beating and coupled to an Alison transmission are as good as you could get at the time.
+mossturn01 The 71 series was probably one of the most reliable and easily-maintained small diesels ever conceived. That was another one of "Boss" Kettering's babies when he was running engineering at GM, that and the EMD 567 in 1938. Ket's drive to perfect the 2 stroke diesel was driven by the tempermental Winton 201s in his yacht. GM bought Winton which later became Cleveland Diesel Division and Ket went on to produce the "GM Diesel" in both 71 and 110 cu. in./cyl. sized in time for WWII.
+DeserT BoB I don't know about the reliable part but they sure weren't long lived . one contractor I worked for had a pair of v16 71s (2 v8 blocks bolted together )that were running generators , that were worn out at 8000 hours . (burned 3+ gallons of oil a shift).and an contractor down the road had one v16 running a generator for a bigger crusher that had over 30,000 hours before he traded it in .
Cbmech Maintenance is everything, as is proper installation. The 16Vs were a bit over the top, as were EMD's 20Vs...too long a crankshaft will do it every time! The old GM trick, "glue two smaller blocks together" was used at GMC Truck (the 702 cu. " V12 cobbled together with two 351 V6s, that 16V71 and 92, both fairly troublesome, and the fuel gobbling 20V645, although the 20V710 is still in every day service eon the RR and, with electornic fuel injection and compound turbocharging, gives good, competitive service. One thing about a 71 Destroit...when things would go wrong, they'd go wrong in a hurry!
Issues with 71s were compounded on the 110,if they weren't leaking oil they were out of oil . The external fuel rails were too long on the 110 and would break ( when I worked on them gm no longer supported them so we had to tap for push lock hose fittings.) The biggest problem with the Jimmy's was running the rack. It was too easy for the mechanic to screw it up and you had a runaway . I got to watch a 12/71 run away after a tuneup . We picked up pieces of cylinder head a 1/4 mile away (I was hiding behind a Euclid rock dump tire)
a local company here in Chambersburg, PA had one of these and being so powerful it literally tore itself apart but yeah really impressive detroit iron for sure
@DSVetDad That thing was unreal! Just to see the power that thing had. It just screamed power. Back in the early 70's I drove a GMC semi with a single 6-71,. Screamin Jimmy I called it. This thing has 2 of them rascals under the hoods. I'm oing pretty well thanks. Hope to have everything squared away soon...
Sorry to comment again but that split frame desighn is just so impressive. Do you know if there are meets like this around the country because id really like to attend one?
Nice videotaping. A few times there I thought you were riding shotgun. I was at this year's show and they weren't digging holes that deep. Cool. Thanks.
Thanks, Glad you enjoyed it. I noticed that this year as well. They must have changed some habbits down there, and stopped them from digging holes. Thanks for watching...
Your not kidding! My ears ring everyday because of those darn Detroits! Ran a mufflered 8v92 cross country for a good many years, and my hearing has paid the price.
The US supplied Sherman tank also used 2 x 6/71 engines since the USSR specified diesel engines for all lend-lease trucks and tanks. By all accounts the soviets loved the GM powered sherman and rated it better than the T-34.
@tompaah7503 I think he may have had a fuel leak or something. It would only do it when he worked it hard. I know later, they where looking at something. Hope it wasn't to serious! Thanks for watching...
@TycoTrainAL No need to be sorry! You are right! That machine impressed the daylights outta me also! Out of the 50 or more fantastic pieces opperating there this past weekend, The TC-12 was my favorite beast. From what I understand, there are shows like this threwout the country, but this one at Brownsville, PA is the largest of its kind. I will be posting a lot more from this show in the next few weeks as I edit them. The usually have this show in May, and again in August. NATIONALPIKE DOT
tyler jackson I Always liked the Detroit's. Yeah they had issues but power ? ? We had Oshkosh snow plows waaaay up north. They had 8V92's in them. A turbocharger feeding a supercharger......V plow with double wings and loaded with 1a's you could overrun the plow and wings so wet snow was rolling over the top of the wings and hammer the throttle and run the revs up against the limiter anytime. They leaked but if you knew what you were doing with the available products when 'replaceplacing' o-rings like the Corvair all leaks could be stopped. Another big plus and the major reason for military or boat applications were they would run as each injector was it's own fuel pump. Dependable as a dropped rock going to hit the ground. Only weak point I know of was the 'dogbone' shaft that drove the supercharger or a mechanic who didn't understand what he was working on. They would run away......again usually operator or maintenance lacking in grey matter. About all you could do is catch it early and drop the 'flap' and hope it didn't suck the seals out of the blower rotor ends......Set the brake, leave the cab, and wait for it to grenade or run out of oil.....either way the engine was history. My uncle had one of these Euclid 12's he got a 'good' deal on it and I remember we pushed it backwards all over the equipment yard with an Allis-Chalmers 31, the Euclid Detroit wasn't the reason as it was screaming at full rpm ! !! Just didn't have enough a**/. Only real problem with it was the cables always screwing up and additional maintenance cost . I was young but operated everything he had and I recall it was a real challenge to operate cutting rough grade as the two hoods moved independently . Course all those big machines you watched the blade end and graded with your butt. Still made you think more was going on than should have been ! ! Remember the Huber road graders ? ? LOL ! ! He had some strange equipment.,.they were all hydraulic , all wheel drive all wheel steering with no steering wheel . One had a 21 foot plow and I remember one of his operators had it standing on it's tail going side wise with the plow almost vertical cutting what had to he a 45° slope or grade on a roadside. To this day I have no idea if they were dry sump lubed or not but they most have been as we never lost an engine in them. He had four. There I go yakkin . ! ! Bye.
Have hauled many pieces of equipment, but never ran across one of these. Must have been very little track on the edge of the trailer when loaded. Outriggers required.
I am pretty sure those grousers are made short deliberately. Two engines, two transmissions, and only two (C6) final drives. Euclid/Terex planetary finals are amazingly tough but...
Yes, this is an awesome machine for the time. 40 ton beast. But this is a twin 2 stroke diesel. 2 Stroke means faster RPM, and shorter engine life. CAT developed the monster D9 at the same time, only a 4 stroke engine was used, a CAT engine. CAT dozers are still used today. What does his tell you?
Actually the 2 stroke detroits ran at the same rpm's any of the older diesels did displacement for displacement. You damn near cannot kill a detroit 2 stroke, have seen them spin a bearing and run like normal. They had the same engine life as any other engine, plenty oft hem still out there running around.
The fact that CAT is a 4-stroke is it's main flaw. These things never sound good, no matter what number if cylinders or cylinder arrangement, are pretty much gutless wonders even with turbos, will overheat and burn a piston on a whim, most were pre-combustion chamber designs which will actually misfire at light loads like a gasoline engine, and also at idle--the 3306 turbo in out 977 did it all the time even in the best of tune, and were fuel HOGS--a gasoline engine of the same displacement won't use as much fuel as those old CAT PIGS did. I learned to HATE CAT stuff--hot running, difficult to work on, require special sockets and wrenches on purpose so you have to buy extremely overpriced CAT tools on many cases, especially the newer stuff from the 1970's on, and deliberately using fasteners in grade 8 that are odd lengths on the bolts or shanks, just so a 1/4-20 bolt wit the CAT logo on the head will cost 25 bucks if you accidentally drop it in the dirt or belly pan when working on it. Frankly, I love Detroits like life itself--sound incredible, have flat torque curves, are as smooth as electric motors, seldom need major service for long intervals, in fact they had the longest oil change intervals of any engine in history---because being 2 strokes eliminates the exhaust stroke, which doesn't put enough back pressure on the rings, so that burned gases blow by the rings even in a fresh engine. The scavenging of the 2 stroke engine pushes the burnt gases AWAY from the rings, therefore, all gases are removed, unlike a 4 stroke which traps alot of burned gases in the cylinder to contaminate the air for combustion, and contributes the well-known heavy black exhaust smoke they produce. As for longevity, expect TWICE to THREE TIMES the life from a 2 stroke Detroit over an older pre-chamber CAT, and at least twice that of any modern 4 stroke. The exhaust temps are low too, and go high on a 4 stroke, the blue smoke you are seeing it likely just a small fuel or oil leak on the manifold, and under high loads, the manifold manages to get JUST hot enough to vaporize this oil and make smoke, possibly just a leaky valve cover gasket. If that were a CAT, it might catch fire--saw oil leaks flare up many times on CAT and other 4 strokes, never anything serious, but they have HOT manifolds that handle ONLY hot gases, and can catch fire--even when fall leaves get in the manifold. A Detroit will NEVER ignite anything on the manifold. They are also notoriously fuel efficient, and pretty much smokeless, due to high turbulence in the cylinder and superb injector design. 4 strokes have to fuel heavily (lots of fuel!) to make any usable power, and added to the poor exhaust evacuation and lack of air induction, even with a turbo, they will smoke heavily, use lots of fuel, and wear out fast as well as overheat easily. And yes indeed, they turn the same RPM's as most 4 strokes, though some CAT engines are actually painfully slow turners, some redlining at a mere 1200 to 1800 RPM depending on the model, and this just makes them even more gutless, and being low compression indirect injection (pre-chamber) engines, they actually DEPEND on the glow plugs for cold starts even in hot weather--they simply lack enough compression to fire easily on compression alone--this results in relatively low peak cylinder pressures, which, coupled with excessively long strokes in a poor effort to get a flat torque curve and more low-end torque, (which it really doesn't achieve too well) results in too low of a general working pressure during the power strokes (which also occur only once in TWO crank revolutions!) makes the engine rather low-powered for it;s large and heavy size, and contrary to what people think, a BIG 6 cylinder like in the CAT D series tractors, with a meager 120 HP will NOT last longer---because being long stroke, even at conservative RPM's, the piston speeds are quite high, and the wear on the rings and sleeves is much higher that a Detroit at full revs all the time, due to their low piston speeds. Also, CAT usually uses STEEL liners, while Detroit uses a special alloy cast iron, and it's well known that steel liners have short life in ANY engine, partly because they are soft, and partly because steel is not porous like cast iron, so it doesn't "season" getting oil into the very grain of the metal, to insure reliable lubrication and plenty of reserve in case oil doesn't splash on the sleeve's walls every time the pistons go up and down, which in reality, it rarely does perfectly. If a steel sleeve starves for oil for just a FEW strokes, it will go dry, being non-porous and having only an oil film on the surface, and not IN the metal itself, it will, when going dry for those few strokes gall badly to the aluminum or iron piston, and either seize the engine or chew the piston and sleeve up badly---saw this on MANY CAT diesels---always thought they were really cheaply and poorly made diesels for being supposedly "heavy duty" engines. They spin rod bearings easily too, and will just seize up when they do--a Detroit will keep on running. (and not even knock!) SO--are 4 strokes more durable? NO. I have seen MANY 4 strokes just quit without any warning and never turn over again, yet have seen abused Detroits seize and and cool off for 5 minutes and restart for more abuse--over and over, so CAT diesels are NOT more durable that a Detroit, in fact are prone to failures, especially the "V" type engines!
You found Detroit in various applications, even rail locomotives for years used this same basic design. What does that say about them? Cat C sees engines today are a flop. Detroit 60 series can go 1.5 million miles in an 18 wheeler. 3406s, couldn't. Cat makes power for sure, and I love the older stuff, but Cat engines of today have nothing I like. Detroit 2 strokes are gone, but never forgotten.
Airsoft! There are two shows this year. The one in August is the big meet. The first show is May 18-19, and the second show is August 9-10-11. This is one fantastic meet. If you are in to an unreal amount of opperating equipment that you can be right next to. Come early, and spemd the day here just off Route 40 outside of Brownsville, PA. You can check their site for more. nationalpike DOT. Com. Thanks for watching...
Beautiful design lines, but now that I see the thing split in half and pivoting, I have to wonder what in hell were they thinking. And that noise! Listen to a John Deere - sewing machines are louder.
LOL, Those Detroits could put out a lot of noise. But they sound good. I sure wouldn't want to be listening to that racket 8 hours a day. Thanks for watching...
GM may have been inspired by the Allis-Chalmers HD-38 (two HD-19s joined together). Customers wanted more power and this was the way GM tackled the problem. As far as noise is concerned, OSHA wasn't around hiding behind every bush looking for violations.
Charles Kettering invented Detroit 2stroke for diesil Zephyr train...and ww2 landing crafts...changed the world! Also invented much if AC Delco electronics..An American Jewish hero...gave huge charity to set up Sloan Kettering Cancer research hospital...
The Detroit was never used for RR service until GMD (Canada) switcher program in the late '50s, and the Budd RDC around 1951, which used 110s. The Zephyrs used their predecessors, the cranky Winton 201A, as horrid an engine as was ever built. The "GM Diesels" (pre-lawsuit name before 1957) were introduced at the same time as Kettering's 567, which changed railroading around the world, in 1938. The first locomotive to use the original 567 was the FT freight road unit...the first one to use in on passenger service was Burlington's E3s, both in 1939. Everything previous used the 201A, which usually required overhaul at only 50K miles. Many were later retrofitted with 567s, such as UP/SP/CN&W's E2s, which were rebuilt in SP's Los Angeles shops as an E7 with two 567Bs.
There are plenty of Detroit diesels at this show: shovels, cranes, bottom and rear dumps, etc. and there's even an ex-marine Case crawler loader with a Detroit diesel.
2 strokes had to be run against the governor , loose a couple of hundred rpm and the torque curve fell in the pit . Detroit didn't lick the problem until right toward the end with the DDEC 92 motor I was good at Jimmie tune up's but I never liked the screaming ba@#ards . My first was a v16 with a good teacher standing over my shoulder
+DeserT BoB they all were in my book but the DDEC 92 didn't have a torque curve of a rock after you lost 200 rpm . With the older engines if you got into the mountains and lost 200 rpm if you couldn't grab another gear just pull over and start over . only good for flat land , boats generators , or automatic transmission
Cbmech Better breathing on those...everything else sorta sucked. Even with the 4 valve heads and N-series injectors, the 71s still had that feature, although it was sure a lot better than the 2 valve heads with the S infectors!!
Cbmech Looking at the blowboy coming from BOTH those 71s in that TC12, I wouldn't expect them to last too much longer if they were in everyday service, either.
Noise. Smoke. Show the oil that's dripping from both of these screamers and you'll have the "Detroit Diesel Trifecta" going on. Twice! This machine is like the booby prize of heavy equipment. So much fail. I hate to be a heavy equipment snob, but run this machine next to a comparable Caterpillar of the same vintage and you'll see exactly why this machine was a huge sales flop. As the previous poster said, they are rare for a reason. Sorry.
Nice video! Also, For God so loved the world, that he gave is only son, that whoever believes in him shall not parish, but have eternal life. *that was the John 3:16 verse for those who didn't know*
If its so great, why did they stop making it? It's high maintenance cost out weighs the minor advantage of two power plants. It is a novelty, but they are rare for a reason.
No doubt about it. Love the sound of thos screamin jimmies. Ran a 430 Detroit in a 1980 White Road Commander cross country for a few years. That sound gets in your head. Fantastic. TRhanks for watching...
YAWN typical GM corporate motto we are insecure and do desparete Engineering ideas for maximum sales.. LOL Sigh if most people would research the typical GM design from just about any product they sell. You will see a bazaar makes no sense from a practical Engineering point of view. Now don't get me wrong this bull dozer would had made a unique prototype.
Ever hear of the EMD Corporation, the one that the railroads in North America used for several decades. Other locomotive manufacturers used the GM 2 stroke motive power in their chassis. How insecure is THAT?

Ohhh man!!! That's great memories. I can't wait untill May so I can see that thing run again. It puts on one heck of a show. Thanks for watching...
awesome
Not sure if the operator know what he's doing working the shit out of it
Double trouble 😔😢😮
Love it at about 1:43 when they show the view to the horizon and all you see is old iron in a sea of diesel smoke!! Awesome.
This is awesome! I've always wanted to go to a vintage heavy equipment meet like this....
Only ever seen pictures and one model of this machine, thanks for the great video!

That's an awesome machine
that thing is SWEET!
Have hauled many pieces of equipment, but never ran across one of these. Must have been very little track on the edge of the trailer when loaded. Outriggers required.
+Sammy Campbell More like no tracks on the trailer. Both tracks either hung off the sides or the dozer was split in two when hauled.
I’ve always seen them split in half when trailered, never in 1 piece.
Needs longer cleats on the tracks for better traction.
I am pretty sure those grousers are made short deliberately. Two engines, two transmissions, and only two (C6) final drives. Euclid/Terex planetary finals are amazingly tough but...
Those GMC diesels need to work hard to produce power.
People would say "Run 'em like you hate 'em!)
The Split Frame is new to me.
You happen to get any CASE equipment in action? If so can you post it please...
I think it’s on fire what horse power is it and I would like to see it up against a caterpillar of its size 👍
This is what a dozer attacking me in my nightmare would sound like.
Sounds like a gigantic pissed off hornet.
Yes, this is an awesome machine for the time. 40 ton beast. But this is a twin 2 stroke diesel. 2 Stroke means faster RPM, and shorter engine life. CAT developed the monster D9 at the same time, only a 4 stroke engine was used, a CAT engine. CAT dozers are still used today. What does his tell you?
Actually the 2 stroke detroits ran at the same rpm's any of the older diesels did displacement for displacement. You damn near cannot kill a detroit 2 stroke, have seen them spin a bearing and run like normal. They had the same engine life as any other engine, plenty oft hem still out there running around.
The fact that CAT is a 4-stroke is it's main flaw. These things never sound good, no matter what number if cylinders or cylinder arrangement, are pretty much gutless wonders even with turbos, will overheat and burn a piston on a whim, most were pre-combustion chamber designs which will actually misfire at light loads like a gasoline engine, and also at idle--the 3306 turbo in out 977 did it all the time even in the best of tune, and were fuel HOGS--a gasoline engine of the same displacement won't use as much fuel as those old CAT PIGS did. I learned to HATE CAT stuff--hot running, difficult to work on, require special sockets and wrenches on purpose so you have to buy extremely overpriced CAT tools on many cases, especially the newer stuff from the 1970's on, and deliberately using fasteners in grade 8 that are odd lengths on the bolts or shanks, just so a 1/4-20 bolt wit the CAT logo on the head will cost 25 bucks if you accidentally drop it in the dirt or belly pan when working on it. Frankly, I love Detroits like life itself--sound incredible, have flat torque curves, are as smooth as electric motors, seldom need major service for long intervals, in fact they had the longest oil change intervals of any engine in history---because being 2 strokes eliminates the exhaust stroke, which doesn't put enough back pressure on the rings, so that burned gases blow by the rings even in a fresh engine. The scavenging of the 2 stroke engine pushes the burnt gases AWAY from the rings, therefore, all gases are removed, unlike a 4 stroke which traps alot of burned gases in the cylinder to contaminate the air for combustion, and contributes the well-known heavy black exhaust smoke they produce. As for longevity, expect TWICE to THREE TIMES the life from a 2 stroke Detroit over an older pre-chamber CAT, and at least twice that of any modern 4 stroke. The exhaust temps are low too, and go high on a 4 stroke, the blue smoke you are seeing it likely just a small fuel or oil leak on the manifold, and under high loads, the manifold manages to get JUST hot enough to vaporize this oil and make smoke, possibly just a leaky valve cover gasket. If that were a CAT, it might catch fire--saw oil leaks flare up many times on CAT and other 4 strokes, never anything serious, but they have HOT manifolds that handle ONLY hot gases, and can catch fire--even when fall leaves get in the manifold. A Detroit will NEVER ignite anything on the manifold. They are also notoriously fuel efficient, and pretty much smokeless, due to high turbulence in the cylinder and superb injector design. 4 strokes have to fuel heavily (lots of fuel!) to make any usable power, and added to the poor exhaust evacuation and lack of air induction, even with a turbo, they will smoke heavily, use lots of fuel, and wear out fast as well as overheat easily. And yes indeed, they turn the same RPM's as most 4 strokes, though some CAT engines are actually painfully slow turners, some redlining at a mere 1200 to 1800 RPM depending on the model, and this just makes them even more gutless, and being low compression indirect injection (pre-chamber) engines, they actually DEPEND on the glow plugs for cold starts even in hot weather--they simply lack enough compression to fire easily on compression alone--this results in relatively low peak cylinder pressures, which, coupled with excessively long strokes in a poor effort to get a flat torque curve and more low-end torque, (which it really doesn't achieve too well) results in too low of a general working pressure during the power strokes (which also occur only once in TWO crank revolutions!) makes the engine rather low-powered for it;s large and heavy size, and contrary to what people think, a BIG 6 cylinder like in the CAT D series tractors, with a meager 120 HP will NOT last longer---because being long stroke, even at conservative RPM's, the piston speeds are quite high, and the wear on the rings and sleeves is much higher that a Detroit at full revs all the time, due to their low piston speeds. Also, CAT usually uses STEEL liners, while Detroit uses a special alloy cast iron, and it's well known that steel liners have short life in ANY engine, partly because they are soft, and partly because steel is not porous like cast iron, so it doesn't "season" getting oil into the very grain of the metal, to insure reliable lubrication and plenty of reserve in case oil doesn't splash on the sleeve's walls every time the pistons go up and down, which in reality, it rarely does perfectly. If a steel sleeve starves for oil for just a FEW strokes, it will go dry, being non-porous and having only an oil film on the surface, and not IN the metal itself, it will, when going dry for those few strokes gall badly to the aluminum or iron piston, and either seize the engine or chew the piston and sleeve up badly---saw this on MANY CAT diesels---always thought they were really cheaply and poorly made diesels for being supposedly "heavy duty" engines. They spin rod bearings easily too, and will just seize up when they do--a Detroit will keep on running. (and not even knock!) SO--are 4 strokes more durable? NO. I have seen MANY 4 strokes just quit without any warning and never turn over again, yet have seen abused Detroits seize and and cool off for 5 minutes and restart for more abuse--over and over, so CAT diesels are NOT more durable that a Detroit, in fact are prone to failures, especially the "V" type engines!
tdshaker The two-stroke Detroit diesel was far superior to the old Cat engines. Its just they did not pass emission standards to keep being made.
ricksbulbs Do you really expect people to read all of that?
You found Detroit in various applications, even rail locomotives for years used this same basic design. What does that say about them? Cat C sees engines today are a flop. Detroit 60 series can go 1.5 million miles in an 18 wheeler. 3406s, couldn't. Cat makes power for sure, and I love the older stuff, but Cat engines of today have nothing I like. Detroit 2 strokes are gone, but never forgotten.
MAN! Lookit', those D-Toys blow a LOT of smoke but also they have no prob's pulling that monster of a dozer outta that hole either!
:)...Sounds like a SEPTA bus going up a hill....
exelent machine
Impressive machine. Why is it blowing smoke from the engine compartment? Blowby?
gm junk
Where can I see one of these in PA?
Brownsville
The Euclid wins my "Bull Terror" Award.
I agree 100% tony. I just love that machine. I could listen and watch it all day. Thanks for watching...
addictive!
Part 2 plz.
That's a dirt mover there now...lol
I had a funny feeling those were Detroit diesels
Airsoft! There are two shows this year. The one in August is the big meet. The first show is May 18-19, and the second show is August 9-10-11. This is one fantastic meet. If you are in to an unreal amount of opperating equipment that you can be right next to. Come early, and spemd the day here just off Route 40 outside of Brownsville, PA. You can check their site for more. nationalpike DOT. Com. Thanks for watching...
also sounded as if they had reached rev limiter if there was one or guess that's why they're screeminjimmies
Beautiful design lines, but now that I see the thing split in half and pivoting, I have to wonder what in hell were they thinking. And that noise! Listen to a John Deere - sewing machines are louder.
LOL, Those Detroits could put out a lot of noise. But they sound good. I sure wouldn't want to be listening to that racket 8 hours a day. Thanks for watching...
GM may have been inspired by the Allis-Chalmers HD-38 (two HD-19s joined together). Customers wanted more power and this was the way GM tackled the problem. As far as noise is concerned, OSHA wasn't around hiding behind every bush looking for violations.
strange but nice...
Brownsville,Pa
Charles Kettering invented Detroit 2stroke for diesil Zephyr train...and ww2 landing crafts...changed the world! Also invented much if AC Delco electronics..An American Jewish hero...gave huge charity to set up Sloan Kettering Cancer research hospital...
The Detroit was never used for RR service until GMD (Canada) switcher program in the late '50s, and the Budd RDC around 1951, which used 110s. The Zephyrs used their predecessors, the cranky Winton 201A, as horrid an engine as was ever built. The "GM Diesels" (pre-lawsuit name before 1957) were introduced at the same time as Kettering's 567, which changed railroading around the world, in 1938. The first locomotive to use the original 567 was the FT freight road unit...the first one to use in on passenger service was Burlington's E3s, both in 1939. Everything previous used the 201A, which usually required overhaul at only 50K miles. Many were later retrofitted with 567s, such as UP/SP/CN&W's E2s, which were rebuilt in SP's Los Angeles shops as an E7 with two 567Bs.
For some reason it strikes me as unusual a Detroit Diesel in a bulldozer
There are plenty of Detroit diesels at this show: shovels, cranes, bottom and rear dumps, etc. and there's even an ex-marine Case crawler loader with a Detroit diesel.
It sounds like it's being revved to death but that engine is a 2 stroke so it just sounds that way.
2 strokes had to be run against the governor , loose a couple of hundred rpm and the torque curve fell in the pit . Detroit didn't lick the problem until right toward the end with the DDEC 92 motor
I was good at Jimmie tune up's but I never liked the screaming ba@#ards . My first was a v16 with a good teacher standing over my shoulder
THe 92 was a piece of crap.
+DeserT BoB
they all were in my book but the DDEC 92 didn't have a torque curve of a rock after you lost 200 rpm . With the older engines if you got into the mountains and lost 200 rpm if you couldn't grab another gear just pull over and start over . only good for flat land , boats generators , or automatic transmission
Cbmech Better breathing on those...everything else sorta sucked. Even with the 4 valve heads and N-series injectors, the 71s still had that feature, although it was sure a lot better than the 2 valve heads with the S infectors!!
Cbmech Looking at the blowboy coming from BOTH those 71s in that TC12, I wouldn't expect them to last too much longer if they were in everyday service, either.
I see where the got the word "MEAN MACHINE" from...
What oil do they use?
Never run anything but straight sae30 in a 2-stroke Detroit
only monograde 30 or 40 weight. never use a multiweight oil in a Detroit
30 weight with low ash content.
WHAT.....WHAT YOU SAY!
LOL
Puro poder
Terex!
fuel knocking bad
"WHAT?!!! NO WE DIDN'T KNOW WHAT HEARING PROTECTION WAS BACK THEN!!"
Noise. Smoke. Show the oil that's dripping from both of these screamers and you'll have the "Detroit Diesel Trifecta" going on. Twice! This machine is like the booby prize of heavy equipment. So much fail. I hate to be a heavy equipment snob, but run this machine next to a comparable Caterpillar of the same vintage and you'll see exactly why this machine was a huge sales flop. As the previous poster said, they are rare for a reason. Sorry.
I could agree more
It ain't a GM unless there's oil smoke belching out the side covers lol
That's right. LOL
โอ้โฮระบบยกใบมีดใช้สลิงดึงขึ้นรุ่นนี้คงเป็นรุ่นโบราณน่าดูเลย
part 2 part 2 part 2!!
Great reliable running engines easy to rebuild but annoying as hell to listen to
I ran a 430 Detroit in a Road Commander coast to coast for several years. They ran fantastic, but that sound will get to yah. Thanks for watching...
Noisy fucking beast
Give me a cat
at 5;06 she is dancing!!! its so elegant. i think i'm in love...
Nice video! Also, For God so loved the world, that he gave is only son, that whoever believes in him shall not parish, but have eternal life. *that was the John 3:16 verse for those who didn't know*
TC12 would easily defeat killdozer
If its so great, why did they stop making it? It's high maintenance cost out weighs the minor advantage of two power plants. It is a novelty, but they are rare for a reason.
Should have said turns on a dinner plate.
can not beat the old detroits rule number drive them like you hate them you wont burn as much oil either
No doubt about it. Love the sound of thos screamin jimmies. Ran a 430 Detroit in a 1980 White Road Commander cross country for a few years. That sound gets in your head. Fantastic. TRhanks for watching...
Jay Wack
guessing that is his wife sitting beside him with no hearing protection I see LOL
two stroke engines?
2 V-6 Detroit 2 stroke diesels, we called them converts, they converted diesel fuel into noise.
Eaaa detroit na presao😂😂😂
YAWN typical GM corporate motto we are insecure and do desparete Engineering ideas for maximum sales.. LOL
Sigh if most people would research the typical GM design from just about any product they sell. You will see a bazaar makes no sense from a practical Engineering point of view.
Now don't get me wrong this bull dozer would had made a unique prototype.
Ever hear of the EMD Corporation, the one that the railroads in North America used for several decades. Other locomotive manufacturers used the GM 2 stroke motive power in their chassis. How insecure is THAT?
Yea, the 327ci and 350ci motors were a flop, nobody in there right mind would buy anything with one of them as the powerplant.
Deafness included!
For sure! LOL. I think one clip, he has headphones on. LOL
Slow stinky and noisey. Retired 40 year operator. Hope to never see one of these again. Catapillar is the way to go!
