Ive been around 6-71 detroits all my life. The fuel rail is very sensitive and if an injector is somehow hung up it will cause the engine to runaway (wide open) the engine in the video sounds like it starts in a runaway and then settles down as the injector re-seats itself. Hard to tell for sure. Anyway, these are great old engines that can run on about anything, but they roar like a lion and pull like a mouse. lol
@southernwaytransport yeah thats true,we had a 318 detroit power unit runnin a saw mill one time and we cleaned the air filters with gas and we cranked it up it was going to blow up we had to hit the emergency stop
@MrMrcrain lmao YOUR NOT THE ONLY 1 ... i learned that way as well working on my uncles internation 4700 dump truck , we also cleaned the air filter with gas , BIG NO NO ! ...NO WAY TO SHUT IT OFF , EVEN WITH KEY OFF , IT STILL RAN ....it pegged the governor till the "gasses " dried up outta the air filter ... :-D
I know Detroit 71's very well and it almost sounds like its running away. You must have had to replace the injectors before attempting to start it after 15 yrs. The fault of Detroit 71s including the 92's, if they set for more than six months there's good chance that one of the injectors will seize while cranking it over. The seized injector, connected to the others via the rack, will holding them all wide open. On a runaway you block the air intake with anything flat or use CO2 to choke it.
I always heard these engines that havent run in years COULD run away on start up from bad seals from sitting ending in a seized engine or thrown rod! I agree it should have idled a bit before letting it go up to governed speed. Ive been told u should stand by w/ a big CO2 fire extinguishers an give it a shot up the intake to kill it if she takes off. old school way is stuff a jacket up the intake but thats not the best idea because it COULD suck oil/air threw the bad seals an continue 2 run
@shamay92 all Detroits are supercahrged, some turbo, some Roots type blower. That whistling you hear is from the compressor it's running. I'm certain this one is using a Roots blower. Due to thier 2 stroke design, they have to have forced induction in order to run correctly.
As to a turbo singing, alot of early designs could really whistle, modern impeller designs are made so as to eliminate this noise.
:50- *koff...koff..." LOL. Cool man. That's a big fucking engine. What was is this thing? An old compressor or generator or something? It looks like it had wheel once upon a time, or something. I love the sound of an old Detroit; the first time I heard one, I didn't believe it was a diesel at all, because the 2-stroke sounds like it runs at such high RPM's compared to a four-stroke. I love how "industrial" they are though. Fucking go deaf standing next to that thing for five minutes!

@jet62095 That's not exactly true. Bactria will start to break down the fuel after a few years creating a slime that will be caught in the fuel filters. But in the 80's high sulfur fuel was available. Great mileage, smokes, but great mileage. Then the EPA mandated low sulfur fuel & the mileage went down. I had a IHC Scout Turbo Diesel. Got 33MPH on High Sulfur Canadian fuel . When I got back to the US & low sulfur only 17-23MPG.
It is an air compressor...the screech is an air leak on the discharge side of the compressor...no bearing noise, just air leaking. We use these on the flight-line in modified form to start 747's.
Wow! I sure do enjoy some of the stupid comments I read on this post. The engine is now sitting in my shop and the rest has gone to the scrapper to be sent to China. I've got a 13spd roadranger to go behind the DD and its going in my 56' International S-160 truck.
do you honestly think that it would run that long if it had no oil in it. ya it should have an adjustable throttle on it. ive seen gen sets that are progammed to red line right off the hop. no oil pressure yet, but its going to 3 grand.if it had no oil it would have lasted for about 20 seconds before it grenaded.
20 mins of crankin and 2 cans of either, she will wake up lol typical detroit thats sat for some time ! I you use them on daily basis you only need 1 can of either lol
@Mitsugejl NO. Absolutely not! You'd get "preignition" where the fuel is igniting B4 TDC. You could throw a rod through the engine block. Even then you with a warm up, you get some preignitionl. That's what caused the rattle sound after it fired up.
Really? It couldnt have been that great to take that thing after sitting for so long and get it started then flog it right up to governed speed. I mean a gen set will run gov speed start to finish but maybe would have been a good idea to bypass gov to let her idle for a few minutes first? sounds good though. enjoyed the video.
The only thing i thought about is if your firing up a gas motor with a hydraulic cam for the first time you go to 3000 rpm for 20min! It peged the oil pressure gauge out @ 80psi+
Indeed, because higher RPMS obviously pump more oil to the cylinder head [ but the main reason is that at higher rpm, theres less load on each cam lobe... along the lines of momentum.]
Dr Diesel developed the Diesel engine to run on coal dust actually, the solid hydraulic injection to inject liquid fuels wasnt developed at that time. All the early engines were air blast injectionof just about anything that could burn.
BTW that 8v71 must be rooted, with no compression to need all that winding over to start. Normally they start straight up even when very cold.
Um, no. Glowplugs heat the air, not the fuel and they are only used during cold starts. A diesel burns fuel by spraying a very fine mist of it into air that has been heated by compression. And yes you can run diesels on just about any kind of oil, be it animal, vegetable or mineral based.
Depends on what engine cummins do both on some engines if glow plug are in the head vs the intake( grid heater) (Deutz 1011 intake heater, 1012 and 1013 glow plugs. If in the head they are all on so some cykinders heat air and fuel mixtures. But i do agree with it is meant to heat the air. Burning newspaper in intake works awesome. Ashes from paper catalise the furl and flame heate the air. Try it with no air folter of coarse.
I don't know about that burning newspaper, sounds like someone is looking for an airbox fire or explosion. Not to mention ash isn't good for any type of engine, you know scored rings & cylinder walls.
Burned paper= Carbon. Carbon is a normal by product of a diesel engine. Also there is no fuel in the air box, thats why is call an air box. Fuel is metered trhough the injectors which are foun in the clylinders on a diesel. Fuel found in intake on a gas engine. Burning news paper in an intake in -20 f is a great way to get large detroit running. You should also try a small fire under the oil pan. SMALL FIRE. Not a raging inferno. Internal combustion engines= internal explosion engines
Carbon does not equal ash. Carbon and water is not corrosive, ash & water is corrosive, lye. Add fat and you have lye soap. Lye and cylinder rings = oh gee, is it time for new liners? And I'm guessing you never pulled the access covers off and cleaned out the airbox, Full of lube oil & carbon, given a hot enough fire and that junk will start. And If you don't believe me, what comes out of the airbox drains?
Actually is does equal carbon. Wood dosen't condust electricity but carbonized wood does due to the presense of carbon. Try it with a dvm on ohm's. its kinda of neat. Ash is mostly carbon. Actually have pulled of air box cover on an 8v71 3 per side double closest to bell housing. rebuilt hydrolocked after muffler let water down right bank. bent two rods and broke two liners at botttom in a half moon shape. Liner to head height width depth gauge 3-5 thousanths. Yeah never pulled one apart.
Oiy! You a stubborn one ain't cha? Try this, get some fireplace ash, or ash from the barbeque, light grey stuff & try to light it. I'll tell you, it won't light. Next, get some carbonized wood, or a briquette, I like kingsford mesquite, it lights don't it? No free carbon in ash. Leach water through wood ash and you get Lye, very akaline, very corrosive. But hey, I'm not your boss, just an internet acquaintance. And this is pointless.
ok for the guys who posted the video so they don't have to deal with the hoards of idiots out there diesels don't use octane infact nothing uses octane it is mearly a measurement of how much pressure the fuel can take before it combusts which is how diesels fire at the top of the pressure stroke a diesel injects fuel so that it combusts that also why diesels don't use spark plugs and ya it would fire i worked on a 1950's track loader and it fired in 2 turns after draining the oil and fuel
Sure it would. Happens to our older Cummins-powered buses in cold weather. We run ultra-low sulphur fuel - modern stuff.
What you were seeing wasn't smoke... it's near-vaporized diesel fuel. Very common occurrence on cold starts with no starting aid (glowplug, ether, intake heater, etc) - the engine won't develop enough heat to ignite the fuel charge and simply push it out the exhaust until it's cranked long enough to warm the cylinders a bit.
@TestECull Ok. Octane VS Cetane. Octane is how has a fuel such as gasoline will burn. Cetane is actually a part of crude oil and is a measurement of how much heat a "distilate" such a jet fuel, Diesel 7 Fuel Oil will burn. The slower the fuel burns the more heat it will produce. Gasoline engines use Octane. Diesels us Cetane.
I dont think it retains oil pressure. It is very bad for a detroit to run backwards. you also cannot turn it off with the key you have to unplug a glowplug wire or take one out while its running.
They don't have glowplugs - those are pretty well limited to automotive applications, with a few exceptions. Some Detroits use ether injection for cold starting, most do not.
Glowplugs, for that matter, only assist in cold starting. They do not cycle once the engine is running and unplugging them will not affect the engine.
Two ways to kill a runaway diesel: shut off the fuel manually (force the rack to full closed for Detroits), or choke off the intake air. Prayer helps, too.
Yet to see a glow plug on industrial 8v 71 6v 53 , 4 53,6v 92. These are all air port aplications. In fact not one detoit diesel athat ia have seen at logan airport have glow plugs. Navistar detroit series 60 dosen't count as a real detroit.
Actually it is. Mabybe you should get out and stay off the internet. Series 40 are known for water pump failures. Impellar (Stainless steel)backs off shaft an migratese backwards and eats its ways through gear/ accesory case (Aluminum). Series sixty can be found in big trucks that go vroom vroom. You should try not to insult people that do this for a living. What do you do for a living?????
i work on them every dam day asshole.i was talking to the prick that said to take the glow plugs out.how fucking stupid is that? and no the series 60 isnt a real detroit because mercedes actually designed and built the engine.oh and learn how to spell dickhead.
Ugggh, back in the late 80's was when the Series 60 came out, I don't recall Mercedes Benz being in the American truck market then. The DD15 Mercedes may have had something to do with. Let's stop with the name calling too. Series 60 is awesome, I prefer a 2006 or older, not to enthused with the '07's.
uggggggggh damn your a retard if you think the 60 is great.and no it wasnt a merc when it first came out.those were the good ones.but the new ones ( 1997 ^) if you can keep turbos,front seals,injectors,and oil pans in one piece then i guess you got a good truck.and why stop with the name calling the douche said to take the glow plugs out.where are they?
Bud, show me your sources, Series 60 is an awesome engine. There you go again, retard, douche bag. Why not try to have an intelligent debate, no matter who is wrong, makes you look like a fool. How about I call you a douchebag because you can't use use capitalization, I'm not? Just quit already, keep it relevent, if there's no glow plugs say there's no glow plugs.
I don't have any sources, my experience around the Series 60 has been excellent, I guess its all a matter of opinion. I'll take a series 60 over a CAT or Cummins. I wasn't challenging you on the glow plugs. Oil leaks happen over time, and no matter if its a CAT, Cummin's or Detroit they all blow turbo's over time.
so 6 different 60s coming into our shop (i work at CAT in riverside when times are tough you work on whatever you can get your hands on) losing turbos and dropping front seals every 50k miles is normal? well i guess since the ISX cummins we get go 15k to a cam.LOL we have CATs that come in with over a million miles and they come in for an oil change.thats it.cummins ive never seen one with over 600k with out a major OH.
the ISX series suck! i had an 07 with nothing but jake brake trouble McCandless in vegas tried telling me that the jakes were "weight sensitive" bullshit when they just up and go from half to full back to half then just quit somethingis wrong, LOL McCandless is run by a bunch of morons ! LOL
wow ummmmmmm older detroits dont have them.thats the engines i know that doesnt have them.cummins,cat ,newer detroits, all have them.you cant start a cummins or detroit with out them.
bigger engines dont need glow plugs for 2 reasons the first being that they create a very large amount of heat becuase they are compressing alot of air into a small place more so than smaller diesels and beacause they are mostly direct injection and you dont need glow plugs when you have direct injection this is the same with small diesels though some do run a heating element in the intake to make them run smoother when cold
@pfalways Diesels of any size will start with no glow glugs. The reason for glow plugs is for quicker starting on car engines where people do not have patience to cold crank a small diesel. On my 1980 IHC Scout Turbo Diesel I only had to use the glow plugs once or twice a day in the warm weather. The compression ratio is the same on any size diesel therefore the compression heat is the same regardless of the engine size.
@mike198748 Because people generally want the engine to start quicker. The glow plugs are in a "Preignition Chamber" which heats the air . People are used to a gas engine which starts right now where as direct injects doesn't. Plus the batteries are smaller if you don't have to cold crank. Trucks take a 8D battery with 24VDC and alot of weight & space. With the glow plugs, two regular car batteries will do.
@heatherandpaul2 A Detroit will run backwards. Happened to my Brother. If the engine stops just right, the compression will kick the piston downwards & the Detroit Diesel will run in reverse. He had 2 speed forward & 13 in reverse. I ran a Fairmont 2 stroke motorcar. No tranny. We just adjusted the timing, cut the ignition, when the flywheel almost stopped, hit the ignition & the engine ran backwards. Any two stroke will do that including a model airplane engine.
Yep, they sure can! Had that happen to our MCI coach bus once (6V92TA, 375-ish hp). Don't know how, but it managed to kick over backwards and continued to run like that until I lifted the lid and yanked the emergency fuel-cutoff. Sounded normal, despite the big red oil pressure warning light and "0" on the gauge!
the myth is in reference to a right or left hand rotation. Put the cam on the other side change gear positions blower postion and the engine will now "run backwards"

Really? It couldnt have been that great to take that thing after sitting for so long and get it started then flog it right up to governed speed. I mean a gen set will run gov speed start to finish but maybe would have been a good idea to bypass gov to let her idle for a few minutes first? sounds good though. enjoyed the video.

The only thing i thought about is if your firing up a gas motor with a hydraulic cam for the first time you go to 3000 rpm for 20min! It peged the oil pressure gauge out @ 80psi+

@TheNickNixon
Indeed, because higher RPMS obviously pump more oil to the cylinder head [ but the main reason is that at higher rpm, theres less load on each cam lobe... along the lines of momentum.]

@sm350bl All of that cranking would get quite a bit of oil pressure built up.... But I totaly get where your coming from.

Dr Diesel developed the Diesel engine to run on coal dust actually, the solid hydraulic injection to inject liquid fuels wasnt developed at that time. All the early engines were air blast injectionof just about anything that could burn.
BTW that 8v71 must be rooted, with no compression to need all that winding over to start. Normally they start straight up even when very cold.

It looks like a generator set, it has to run at a fixed RPM for the frequency from the alternator to be correct.
asagarinene 2 years ago
Um, no. Glowplugs heat the air, not the fuel and they are only used during cold starts. A diesel burns fuel by spraying a very fine mist of it into air that has been heated by compression. And yes you can run diesels on just about any kind of oil, be it animal, vegetable or mineral based.
1skullcracker 2 years ago
Depends on what engine cummins do both on some engines if glow plug are in the head vs the intake( grid heater) (Deutz 1011 intake heater, 1012 and 1013 glow plugs. If in the head they are all on so some cykinders heat air and fuel mixtures. But i do agree with it is meant to heat the air. Burning newspaper in intake works awesome. Ashes from paper catalise the furl and flame heate the air. Try it with no air folter of coarse.
ianc435 2 years ago
I don't know about that burning newspaper, sounds like someone is looking for an airbox fire or explosion. Not to mention ash isn't good for any type of engine, you know scored rings & cylinder walls.
1skullcracker 2 years ago
Burned paper= Carbon. Carbon is a normal by product of a diesel engine. Also there is no fuel in the air box, thats why is call an air box. Fuel is metered trhough the injectors which are foun in the clylinders on a diesel. Fuel found in intake on a gas engine. Burning news paper in an intake in -20 f is a great way to get large detroit running. You should also try a small fire under the oil pan. SMALL FIRE. Not a raging inferno. Internal combustion engines= internal explosion engines
ksoldato 2 years ago
Carbon does not equal ash. Carbon and water is not corrosive, ash & water is corrosive, lye. Add fat and you have lye soap. Lye and cylinder rings = oh gee, is it time for new liners? And I'm guessing you never pulled the access covers off and cleaned out the airbox, Full of lube oil & carbon, given a hot enough fire and that junk will start. And If you don't believe me, what comes out of the airbox drains?
1skullcracker 2 years ago
Actually is does equal carbon. Wood dosen't condust electricity but carbonized wood does due to the presense of carbon. Try it with a dvm on ohm's. its kinda of neat. Ash is mostly carbon. Actually have pulled of air box cover on an 8v71 3 per side double closest to bell housing. rebuilt hydrolocked after muffler let water down right bank. bent two rods and broke two liners at botttom in a half moon shape. Liner to head height width depth gauge 3-5 thousanths. Yeah never pulled one apart.
ksoldato 2 years ago
Oiy! You a stubborn one ain't cha? Try this, get some fireplace ash, or ash from the barbeque, light grey stuff & try to light it. I'll tell you, it won't light. Next, get some carbonized wood, or a briquette, I like kingsford mesquite, it lights don't it? No free carbon in ash. Leach water through wood ash and you get Lye, very akaline, very corrosive. But hey, I'm not your boss, just an internet acquaintance. And this is pointless.

ok for the guys who posted the video so they don't have to deal with the hoards of idiots out there diesels don't use octane infact nothing uses octane it is mearly a measurement of how much pressure the fuel can take before it combusts which is how diesels fire at the top of the pressure stroke a diesel injects fuel so that it combusts that also why diesels don't use spark plugs and ya it would fire i worked on a 1950's track loader and it fired in 2 turns after draining the oil and fuel

There would be no octane left in 20yr old fuel, it simply wouldnt run on 1980 fuel.

Diesels don't really need octane. It would run on 1980 fuel, obviously, because it did. New diesel would NOT have been that smokey...
TestECull 3 years ago
wrong new diesels are also very dirty city buses, fire engines, and trains.
ksoldato 2 years ago
Sure it would. Happens to our older Cummins-powered buses in cold weather. We run ultra-low sulphur fuel - modern stuff.
What you were seeing wasn't smoke... it's near-vaporized diesel fuel. Very common occurrence on cold starts with no starting aid (glowplug, ether, intake heater, etc) - the engine won't develop enough heat to ignite the fuel charge and simply push it out the exhaust until it's cranked long enough to warm the cylinders a bit.
Alisterwolf66 2 years ago
@TestECull Ok. Octane VS Cetane. Octane is how has a fuel such as gasoline will burn. Cetane is actually a part of crude oil and is a measurement of how much heat a "distilate" such a jet fuel, Diesel 7 Fuel Oil will burn. The slower the fuel burns the more heat it will produce. Gasoline engines use Octane. Diesels us Cetane.

running backwards. So hoe does the engine retain oil pressure if the oil pump is runnig backwards
ksoldato 2 years ago
I dont think it retains oil pressure. It is very bad for a detroit to run backwards. you also cannot turn it off with the key you have to unplug a glowplug wire or take one out while its running.
BiohazardDingleberry 2 years ago
You don't take out a glow plug when an engine is running unless you want to lose a limb.
That also won't help - if you want to stop a runaway you choke it with CO2.
silicon212 2 years ago
They don't have glowplugs - those are pretty well limited to automotive applications, with a few exceptions. Some Detroits use ether injection for cold starting, most do not.
Glowplugs, for that matter, only assist in cold starting. They do not cycle once the engine is running and unplugging them will not affect the engine.
Two ways to kill a runaway diesel: shut off the fuel manually (force the rack to full closed for Detroits), or choke off the intake air. Prayer helps, too.
Alisterwolf66 2 years ago
glow plugs on a detroit = news paper kerosine and a match. remove air filter throw in intake. does work well.

Yet to see a glow plug on industrial 8v 71 6v 53 , 4 53,6v 92. These are all air port aplications. In fact not one detoit diesel athat ia have seen at logan airport have glow plugs. Navistar detroit series 60 dosen't count as a real detroit.

yeah its not a real detroit.ive been all over websites and still cant find it.i dunno what he was on about
robby844 2 years ago
Actually it is. Mabybe you should get out and stay off the internet. Series 40 are known for water pump failures. Impellar (Stainless steel)backs off shaft an migratese backwards and eats its ways through gear/ accesory case (Aluminum). Series sixty can be found in big trucks that go vroom vroom. You should try not to insult people that do this for a living. What do you do for a living?????
ksoldato 2 years ago
i work on them every dam day asshole.i was talking to the prick that said to take the glow plugs out.how fucking stupid is that? and no the series 60 isnt a real detroit because mercedes actually designed and built the engine.oh and learn how to spell dickhead.
robby844 2 years ago
Ugggh, back in the late 80's was when the Series 60 came out, I don't recall Mercedes Benz being in the American truck market then. The DD15 Mercedes may have had something to do with. Let's stop with the name calling too. Series 60 is awesome, I prefer a 2006 or older, not to enthused with the '07's.
studpuppy69 2 years ago
uggggggggh damn your a retard if you think the 60 is great.and no it wasnt a merc when it first came out.those were the good ones.but the new ones ( 1997 ^) if you can keep turbos,front seals,injectors,and oil pans in one piece then i guess you got a good truck.and why stop with the name calling the douche said to take the glow plugs out.where are they?
robby844 2 years ago
Bud, show me your sources, Series 60 is an awesome engine. There you go again, retard, douche bag. Why not try to have an intelligent debate, no matter who is wrong, makes you look like a fool. How about I call you a douchebag because you can't use use capitalization, I'm not? Just quit already, keep it relevent, if there's no glow plugs say there's no glow plugs.
studpuppy69 2 years ago
theres no glow plugs.and my sources are my self.we get 60's in every 50K for new turbos and front seals.wheres your proof they are great?
robby844 2 years ago
I don't have any sources, my experience around the Series 60 has been excellent, I guess its all a matter of opinion. I'll take a series 60 over a CAT or Cummins. I wasn't challenging you on the glow plugs. Oil leaks happen over time, and no matter if its a CAT, Cummin's or Detroit they all blow turbo's over time.
studpuppy69 2 years ago
so 6 different 60s coming into our shop (i work at CAT in riverside when times are tough you work on whatever you can get your hands on) losing turbos and dropping front seals every 50k miles is normal? well i guess since the ISX cummins we get go 15k to a cam.LOL we have CATs that come in with over a million miles and they come in for an oil change.thats it.cummins ive never seen one with over 600k with out a major OH.

robby844 2 years ago
bigger engines dont need glow plugs for 2 reasons the first being that they create a very large amount of heat becuase they are compressing alot of air into a small place more so than smaller diesels and beacause they are mostly direct injection and you dont need glow plugs when you have direct injection this is the same with small diesels though some do run a heating element in the intake to make them run smoother when cold
pfalways 2 years ago
huh ok makes sense, i new they were direct injection but never thought of the how much heat they create LOL thanx
mike198748 2 years ago
@pfalways Diesels of any size will start with no glow glugs. The reason for glow plugs is for quicker starting on car engines where people do not have patience to cold crank a small diesel. On my 1980 IHC Scout Turbo Diesel I only had to use the glow plugs once or twice a day in the warm weather. The compression ratio is the same on any size diesel therefore the compression heat is the same regardless of the engine size.
strobx1 1 year ago
@mike198748 Because people generally want the engine to start quicker. The glow plugs are in a "Preignition Chamber" which heats the air . People are used to a gas engine which starts right now where as direct injects doesn't. Plus the batteries are smaller if you don't have to cold crank. Trucks take a 8D battery with 24VDC and alot of weight & space. With the glow plugs, two regular car batteries will do.

heatherandpaul2 2 years ago
@heatherandpaul2 A Detroit will run backwards. Happened to my Brother. If the engine stops just right, the compression will kick the piston downwards & the Detroit Diesel will run in reverse. He had 2 speed forward & 13 in reverse. I ran a Fairmont 2 stroke motorcar. No tranny. We just adjusted the timing, cut the ignition, when the flywheel almost stopped, hit the ignition & the engine ran backwards. Any two stroke will do that including a model airplane engine.
strobx1 1 year ago
Yep, they sure can! Had that happen to our MCI coach bus once (6V92TA, 375-ish hp). Don't know how, but it managed to kick over backwards and continued to run like that until I lifted the lid and yanked the emergency fuel-cutoff. Sounded normal, despite the big red oil pressure warning light and "0" on the gauge!
