DD 453-T runs away! rack gets stuck on valve cover. almost lost some fingers too, it was all i could find. F'ed up new turbo compressor wheel, was only damage thankfully!
It probarly will still break, im now in school and my teacher had an old ford tractor (6 in line) that also did this. It leaked oil to the cilinder and then in just goes. He stopped air intake so it was alright, but an half year later it still broke
@@truthsmiles I do not think that this video is able to replicate all the signals that this engine was giving to everyone near him when he was trying to rip itself apart... Do not say she is no a loving woman and everything but she was most likely scared(rightfully).
@@joepenfield Bus Grease Monkey tells a story of when his ran away and he only had a towel which got sucked into the airbox, which chewed it up then spit out the flaming pieces, some of which flew through the open side window of his wife's car.
I saw a mechanic at work who have thrown a whole jacket in the intake of a MTU V10 ! (Yes, the one that's in a Leopard tank) A runaway on such a big engine is scary ! I could feel the power on the ground while the engine was on the testbed.. the whole building was shaking ! normally the engine produce 830bhp but mechanic saw a reading on the testbed (afterward) that the engine peaked at more than 1000bhp (the scale end at 1000bhp)
Erin the angry, No you can't honestly say it since he obviously didn't use his bare hands. He stuffed a rag in it. Imagine if he honestly used his bare hands to plug it up with :-O
BDNeon still wasnt a nice save. Nice would have been if he didnt destroy the turbo by using a kind of plate to stop the airflow or whatever. I'm not saying that what he did was stupid, but it just wasnt a nice save
max it was the turbo that caused the runaway problem in the firstplace so he never caused any real loss as the turbo was already leaking oil causing the engine to go wild.
That's why we kept a "panic button" handy... A piece of plywood with a handle attached to cover the intake . Learned that one in that Canadian Armed Forces . 😁
@eggmanwi usually there's an emerg shut off flap on Detroits , you are supposed to remove the valve cover, move the rack to make sure injectors aren't stuck, and that they return to idle position .. you then test start it with the valve cover off and a vice grip on the rack , throttling from there to make sure everything is loose in the rack.. and she bumps off the governor.. sounded like stuck injectors was all.. as for a real runaway, the engine starts feeding on it's own oil, usually from a cracked piston, as high pressure oil lubes the skirts..makes it into the ports.. then..good luck stopping it, even choking the air wont help, it'll just suck it from the crank case via whatever hole was made in the engine, or past the rings, or whatever.. ..take cover lol..
neat! thank you for protecting our country! thinkin about going down the road of CAF, maybe as a mechanic. hope if i do, that i dont see alot of runaway!
When starting an old 2 stroke detroit, keep a tool box tray around to cover the turbo. Be sure it is big enough to cover the whole turbo. Most of the 453's had blower flaps that you could flip shut with one finger and keep them all.
Blower flaps were a option. Not all engines came with them. I spent part of two years selling Exxon flap kits for their fire pump engines all over the gulf. Take care.
Out of all the runaway videos ive seen, this is the first smart guy caught on camera! So many videos you see them cool the runaway engine with fire extinguishers and no one thinks to stuff the intake. Hat's off to you, man!
It makes a lot more sense if you have a fire extinguisher to just fire that right into the intake instead. If it's sucking co2 instead of oxygen it's not firing
@@Twinspinner Exactly. Flood the intake with CO2. Blocking the airway creates a negative pressure assist. Might be marginally better but CO2 blast is safer imo
CO2 snuffs it out. They all need oxygen to run. Block the air intake fine but don't damage the engine in the process. In other words, think and be prepared.
That was great thinking and reaction. When I was in training on 6-71's (at Fort Eustis VA before a year-long excursion to Vietnam) the instructor told us to always carry a rag and a 1/2" wrench when/if this happens. Good to see how quickly you reacted. Nice!
@@mikegauthier3617 it was to remove the air cleaner on the blower (marine engines). Then we were to toss the rag in to stop the blower. I can't imagine standing there doing this with a runaway 6-71! But some guys did. One of our jobs was to take the LCMs and LCUs out of mothball and put into service. They are an amazing feat of engineering and reliability.
I trained at Fort Lee, VA right next door to become a Mechanic for the Army. Did it for 6 years then became an Officer. Thank God I never had this happen to me on the Detroits and Caterpillars 🤣🤣
j polar,,,,,,,,,this guy is a moron,,,,,,,,,,,,,,,he should have had the emergency shut down hooked up and all he would have had to do would be to trip the lever and all air would be blocked off.....
Me: I'll be outside working on the car. Wife: How long will that take? Me: As long as it takes to get it done. Wife: Okay smartass. (She then leaves me alone. Problem solved)
Those pesky 2-strokes will do that. First time it happened to me it scared hell out of me. I learned to always know where the emergency shutoff was and to keep something handy to shut off air. I’m surprised the turbo didn’t eat what this guy used. I east he knew what to do.
This guy has guts. He snuffed it out and could have carved his hand up in the process, but saved his engine. I would have run in the other direction, watched my Pistons launch everywhere and then been very pissed off!
From what I've seen the engine actually blowing like you said seems to be quite a rarity in these situations (with idiots huddling around the car trying to figure out what's wrong).
Fireship1 then good thing this wasn’t you, because you would have wrecked this engine as a result of making a retarded decision to not do something as simple as choking the engine. ALWAYS carry something dense to throw over the intake when working on older diesels like this, not that a newer diesel will NEVER run away on you, but it’s rare.
if you're concerned about runaway you need a ball valve on the fuel line. best way to stop a diesel is stop the fuel. i pull the fuel line from the tank to stop a motor that just won't quit. have it ready before you start!
@@catlady8324 Since deisels run on compressed air like trains, jets, and cruise ships, they can runaway. So you can't stop them by cutting off the fuel (lubricant) you have to stop the air intake. See jet fuel hoax.
My buddy launched my old Pete, said he knew how to adjust the Jake, so when it went, and we had zip to plug off the turbo, it ran at about 20k till we could pop a fuel line, the engine held but I imagine we took 100k off her life🤣🤣🙄
Furkan Yıldırım_ProPlus Detroit’s will and do rev higher than most diesels we had a 8v92 silver and it was really happy going down the road at 2,100 to 2,300
In my diesel class at the vocational school, years back we were standing around the Detroit we just rebuilt....in wittingly the instructor loosened the screw on the Governor...when we started it she ran.....we had the metal plate for the intake
I always viewed their vtec ads more for fuel economy/efficiency to be completely honest with ya. I'm not a honda fanboy, but definitely not the worst brand in my book either.
Good quick thinking. My friend had his Duramax run away from him when he was tinkering in his garage. That's when the instruction manual turns into the destruction manual. He annihilated his turbo but the engine was mostly okay lol
Probably my favorite video on RU-vid. The rolling mountains in the background, the screaming Jimmy, and the rowdy country music playing in the background. Its almost perfect.
at least he was quick thinking, I always kept an old mud flap nailed to a piece of 2X6 when playing with the Detroits , the mud flap would seal off any air and the 2X6 would keep it from being sucked in,.
Hand was safe, the chunk of rubber? Plastic? Plywood??? Gave it's life.... Might have given himself a raspberry, but that's about as safe as he could have done... Much better than others I've seen, who panicked!!!
Well, youtube put this in my recommended, haven't seen a runaway in a bit but god damn that was the quickest and cleanest reaction, most will be running around the thing looking for the magic red button to stop it, did great mate, hopefully it was just the comp. wheel, no fingers lost, no fires, and no one injured, did great bud.
I rebuilt the Rosamaster fuel pump on my Dad's beloved 856 IH. When I was picking up the rebuild kit and getting pointers from the dealership I was warned that if I didn't put a certain linkage in correctly I could have a runaway. After stationing my Dad at the fuel shut off and sweating bullets when the engine caught after bleeding the air out all was well. Nice quick thinking and better the turbo than the entire motor.
Lucky you had good reflexes, most people, including myself would probably have just panicked and not known what to do, but you managed it nicely! A broken turbo is a small price to pay to save the rest of the engine!
For sixty dollars, I built a snorkel with a valve and an adjustable clamp for the air intake for working on diesels. If anything goes pear shaped, you can just throw the lever and cut off the air. Best sixty bucks i ever spent.
@M Bacon the seals will momentarily leak oil while under high vacuum. Just like having too high of oil feed flow. I doubt anybody with a draw through carbureted turbo setup has ever had a seal issue related to vacuum
as a dock master and mechanic at my dad's marina in the 80's, a nice yacht came in for fuel. After their short stay he re-lit the two 12-71 Detroit Diesel engines just to have one run away. Unfortunately, his close air dam cables were so corroded that they were frozen, and this 12 cylinder engine "grenaded" with me standing on the dock watching, and unable to do anything. After the dust settled, repairing this engine was a big job. The supercharger came apart blowing metal fragments into the cylinders and gauling all the pistons, and finally a broken rod stopped the beast. I will tell you, a run away DD of this size is a frightening sound.
He wasmt in danger if you pay attention. Why do you think he was so cautious? He practically threw the rag (or whatever it was) and ducked for cover. Then firmly and accurately placed his palm over the opening with his fingers clearly out of the way, not grabbing the rag. Accidents can happen; That's why you should be educated, prepared, and careful.
Yeah because god forbid she fuckin learn something right? She stood still and kept her mouth shut when it mattered and let him handle it. Asking questions afterwards is totally fine.
That's the best video ever lol. AT first, I thought this was a normal 4 cylinder diesel engine, but now, after 5 or so years, I know this is a two-stroke diesel, and that's why it "revved" so high.
Worked on diesel engines for 30 years only had two runaways,one was a Detroit Diesel 6-71 out of an Ingersoll-Rand Air compressor.Governor failed in wide open position,,I had started the engine without an aircleaner installed.Blower was wide open to the air.Engine self destructed.Hell of a mess to clean up too.Other engine that ranaway on me was an old Continential (sp)Red seal 6 diesel that was being used as a training aid.This was the engine that you had to change the Roussa Master(sp) fuel injection pump to change the engine RPM from 1200 to 1600 RPM.After a pump change we restarted the engine,governor did not even try to hold rpm,engine RPM kept increasing until broke up,this one threw part of a connecting rod through a cinder block wall.Fun times.
i had my first one run away on me a few weeks ago, it was an international harvester model 1854, dont remember what the engine was but it was a straight six diesel that had been sitting for 15 years, i stuck a couple batteries on it and shot some ether in it just to see if it would fire cause i didnt want to invest too much of my time into it if it was never going to run, i shorted the solenoid out with a wrench and cranked it up and HOLY SHIT... i fell to the ground and nearly passed out just from the mixture of fear of death, adrenaline and shock, i ran about 30 yards and stopped and watched, luckily i had taken the fuel tank off and the only thing it had to run on was 15 year old diesel that was still in the lines so it died after 15 or 20 seconds, it slowed down slowly so im pretty sure nothing major went wrong internally, i know everybody on youtube is mad at me for using ether on a diesel, any ideas on what might have went wrong cause i still would like to fix it up, im open too suggestion.
Lord Sandwich I searched for a video but without luck, theres actually a 2jz powered SUV from a place in middle east that had that happen while on a dyno, it was a huge mess, but I think it was on a compilation, so I cant really help you on that
Probably one of two things went wrong. The first is that you drowned the engine in ether. I doubt that possibility as you probably know better. (And really, using ether on an old engine like that is fine, as long as you do so sparingly. You just don't want to use ether on a newer engine.) The second and most likely possibility is just that the governor is gummed up from sitting so long. You could take the pump off and clean it yourself if you are handy with such things. If that isn't something you are good at; you could probably take the pump to a local shop to be repaired for not too much money. Either way, that isn't a show stopper. You probably expect to have to put several hundred into that engine to get it running again anyway. I don't think putting $200.00 into the pump is a big deal if the rest of the truck is worth it.
Handsome The turbo was probably the cause of the runaway in the first place, it probably leaked oil into the engine and since Diesel engines can run on just about anything it started going, so the turbo probably broke before this situation, the turbo was already lost
@@ericsson_motorsports The guy literally says why it ran away, nothing to do with the turbo (you can see it's pretty much new), it was the injector rack jamming open on the valve cover.
With older Detroit diesels are known for the rack sticking when there is reports the engine taking off as some diesel mechanics have an aluminium clipboard in their toolbox when they know to stop a runaway Detroit is to snuff out the air when the few were to award the mechanic a thug award for risking their life to save a runaway.
She's gonna blow, Cap'n! I had a go-kart get a stuck throttle cable while I was riding it once, I had the same snap reaction to choke the intake. Feeling your hand around a hot engine behind your head to try to save your ass while doing 30 down a dirt road is probably what it feels like to be a fighter pilot in combat, and what this guy did must be what it feels like to be a bomb technician. Who says a mechanic's life is boring?
bobby jeo You might want to re-read my comment. I was saying I had an experience with a runaway engine, and saying that in my own case it was due to a stuck throttle cable, I made no claims of knowing what caused the Diesel to runaway as I don't work with diesel, only gasoline and turbine.
currjo10 it's functionally the same when it's a pullstart with no kill switch and you're weaving down a dirt road with corrugated steel drains on each side.
+Tanya Sapien lol you are a clown. No one cares about your home made go kart story, we came to see a diesel runaway. Your go kart was not a runaway. Fact. A runaway is when a turbo blows its seals and consumes the engine oil and coolant as fuel and runs wide open.
@@bradyn4212 it was RL for that guy. My HS machine shop teacher used to show videos to the grade 9 students about the dangers of long hair and loose clothing. That was 'til some wishy-washy parents complained. Then periodic accidents happened in his shop. 🙄
