i am a grad .of nadc (1991) ended up getting my cdl and driving truck for 15 years,haven't seen a road engine yet get 10 mpg ever!bobtail maybe.have had better luck with cummins an cat for hill power.detroit is used more because frightliner had a contract with them and there about the cheapest trucks on the market.
@2253benjamin The engines in this class are training aids. All we did was remove the turbo, intake and exhaust manifolds, rocker shaft, camshaft, EUIs, head, oil pan, oil pump, and a piston and cylinder liner. Then we had to put it back together and run it. Theses engines suffer alot of abuse, they're frequently taken apart and put back together and then run for a short period of time. When we pulled it apart the bearings showed massive wear from poor lubrication.
@quesomarabilla i work in the patch and have run many trucks, detroits wernt to bad of an engine, they are the best on fuel vs. the rest but from my experiance cat and cummins will out pull a jimmy. they arnt as nice to shift, and dont have the jam of the others, there is a couple detroits out there that will kick the shit out of anything but they are few and far between, over all id say they are better suited for highway hauling. id say that it depends on the application that u r using it for.

ya i run oilfield and my new bed truck has a series 60 and i hate it. i was driving a c15 before, and this detroit i have now absolutely sucks. sorry,
For an oilfield application, these series 60's are not that good. Overheating and electrical failures are common. The older 2 stroke Detroit's are much better, more reliable and never give up.
i have to disagree with gllre i have been around deisel engines all my life and detriot diesels are the one deisel that i whouldnt have in any of my newer trucks i have rebuilt many series sixtys just my opion
@egpg2000 these engines have been pulled apart hundreds of times more that what is expected in the field. There is no problem, just learning students.
i just went from a '06 KW with a Cummins ISX to a '08 Freightliner with a series 60 and all i can say is i miss the cummins. It REALLY stinks that you can't get a Caterpillar anymore. Stock for stock it's a little more powerful than a C-15, but just barely. MPG ranges from 5.5 to 6.5 hauling double bottom dump trailers.
i would like to take issue with your recommendation of this engine..after having lived with one for almost a million miles..they are in reality considered to be an inferior product in the long haul diesel market..a discount throw away engine.10 mpg is unheard of and the reality is more like 6mpg hauling lite with a tail wind..and also you can expect major issues anywhere around the 700,000 mile mark...scuffed liners cracked timing covers excessive blow by and various oil leaks are the norm.....

@richardtheone 10mpg is unheard of...it's more like 8 if the driver isn't trying to drive it like a CAT. Scuffed liners are usually from poor maintenance, I.E. replace your damn air filter. Never seen a cracked timing cover, only leaking ones...and that was before the cover brace update. Blow by causes oil leaks, and usually blow by is from bad maintenance again. The lesson, take care of them, they take care of you... 1 million is not uncommon for these things...I see it every day.
can you tell me bout taking the fuel pressure on the series 60, i know you have to check the pressure on the output of the fuel filter, but is there a place to plug it or do u put an adapter right on the output??
@polaris692 You check fuel pressure at the lower port on the fuel pump. There's usually a fuel temp sensor there, but you can remove it and plug in a fitting to check pressure....pressure depends on DDEC level and if it has an R80 fitting or not.
They look fresh! That's number 12 towards the front right of the diesel shop. We had engine 4 closer to the tool room and by the two cat c11's and the four c15's. They still had the fans in all of em' at that time. When I was in that class none of them had the fans in them. Some retard might have lost a finger!
truckinjeff;canyou tell me the name of the control box to control the engine,and if i can buy one,in the dominican republic truck owners are replacing electronic engines for mechanical,because most mechanic cant bench test those engines,thank you,pabl.
@Pablito817 I don't know who makes that control box. My assumption is that it was made by Detroit Diesel for Dyno stands or Marine remote control. The box maybe custom made if you know electronics pretty well. You have ignition signal, throttle position, check engine and engine warning lights, also gauges and diagnostic tools that communicate to the engine through a J1708 databus.
I used to work for the company that machined the rocker arms and did the assembly.We also ground the shafts for the assemblies.I worked in the area that machined and assembled the Accessory Drives.That was a good program for us and provided overtime for about 10 years.
I seen a 71' series with no gov' run away, started sucking oil outa the crank case. We keep a block of wood by the turbo to cut it out, but the guy threw a phonebook in the turbo, and it sucked it up, shredded it. It stopped, after a couple hundred pages lol.
a buddy of mine put one of these in a AM General bus with a allison manual trans. and he is getting 12 to 16 mpg. Could not believe it. even better on BIO.
i have a1999 9400 international eagle with a500hp serie60 the oil pressure start 60 and 20 whent it hot at 6rpm and stay on 40s whent is runing that ok or not
@TheDieselpowers make sure you know what you are getting yourself into, it can be a decent school, but some of the teachers are a pain. its not an easy school, and it is fast paced, and It will be challenging, and reps pretty it up a lot. Also, I would suggest getting your own toolbox and a halfway nice set of tools before you come here, the napa that is issued isn't that great. Also, be looking for scholarships.
All Detroit Diesel engines represent toughness, except the Series 40 engines. The Series 40 sounds too smooth like the Cummins engines and no toughness at all
these engines are the 11.1, and the cross head articulating piston is the most effecient design for this engine, because it is more durable than a full aluminum alloy piston, and weighs less than a fully cast iron piston.
well i tell ya what its more efficient at , and that is putting you out of business when your an owner/operator and #5 piston breaks 4 times and they can't tell you why. I heard later while i was filing bankruptcy that there is supposedly a bad batch of pistons out there. Sux to be the receiver of the bad batch lemme tell ya . I have a Mack piston out of a E6 350 thats aluminum that has a valve head beat all the way through it and it still was running. but missing and the piston didn't explode
well, im sorry that you got hold of a bad set, the piston changes directions 2 times every revolution, so at 2,000 rpm its stopping and starting 4,000 times a minute. those forces put unimaginable strain on the conecting rods and cranckshaft because of the massive weight of the medium/large bore piston. A solid cast iron piston would cause more troubles than it could solve in this small of an engine.
The 14 liter had to have its piston and rod installed in the sleeve before it was installed in the block because of the size of the rod journal, it was built for the weight. The articulating piston was pleanty strong. Either you had a bad piston, or (if you broke the same piston 4 times) an unidentified issue with your engine, which is more likley the cause.
i'm not the only person thats had #5 piston issues with a 12.7. Search the net and talk to mechanics. Its a design problem of some sort. I've heard some had piston cooling through the rods , i haven't checked on that yet.
I loved the way it ran , when it ran. The area where the pin goes through the crown looks light weight to me. Thats where mine kept breaking
The old 12.7 had the cast pistons, the problem with # 5 was stress on the crown causing a piston _ dome separation. the new design started with the mk series model. ok the mk bk, pk ect. all have a new alum. piston ,drilled rods for oil to cool the complete piston and skirt assembly along with oil squirters that bolt into the block also helping to cool the piston. the new engines from o7 and beyond have some of the same improvements plus more.
i wonder if i tell my sad story to Detroit if they would help me get another truck ,,lol,,, i hear there is a bunch of repo's out there ,,,, i loved the way it ran , when it ran ,,
LOL you are among a lot of people who have tried to do just that, some big companies have won the battle, lets say Swift snider yellow to say a few. but the poor owner op. usually got it up the, well you know where. just get your hands on a DD15 that engine will blow your mind !!
i've heard some people tried to sue detroit over the piston deal ,,, its a shame really ,,, the 12.7 reminded me of the best truck engine ever ,, E6 350 mack , but with enough power ,,, it really was great when it ran
You're definitely not the only one. The older detroits (12.7) had this problem and it was a piston dome failure, design flaw in the piston. I'm a tech at a freightliner dealer and we've done our share of repairs like that.
the dealer here wanted 8500.00 to do one cylinder ,,, i had a friend that could pull the head and have it back running in 2 days usually ,, after he could get to it ,,
Now detroits a good engine,I bought a 2000 freightliner century class with 680,000mi when i got it ,nothing fancy but now it has 1,228.354miles and never did anything to it but keep it serviced and its still strong,
You talking about that blue silicone boot or the 45 degree angle fitting? Any truck dealer, shop, parts supplier will have the boot. I think that was a Garret turbocharger, that angle fitting should be able to be found at a Detroit engine shop or very likely a Freightliner dealer (since Detroit is owned by Freightliner).
I can't stand working on detroits, in or out of the truck... Give me a Cat or preferably a Cummins. They run good, but they just annoy the shit out of me.
man, CAT dont even build the fuckers anymore. in about 40 years it will just be Detroits on top :P big beast this engine, 100 times better and 100 times more efficient than a CAT
I am glad to see NADC still exists. I graduated in June 1985. In my days there, the world was just beginning to try DDECing the two strokes. BCIII & BCIV NTC were hot, and Cat was cleaning up the 3406 for replacing 3408. That was a simpler day and time. No lap top was needed. Now Cat on-highway is almost over. Detroit, please bring back the "92's" and "71's". Cummins, I have lost "INSITE". I have to stand and think "B","C","L","M", or "X". NTC 230-475 used to work just fine.
Where can I find information on modifying the S60? I have an 11.1 - would like to go with more fuel, more boost, etc... Where can a person get part numbers, info, etc. to do this?
I have a any question, why International (Navistar) and Kenworth (Paccar inc) not offers the Detroit engines in your trucks today?, but in your webs just offers Cummins and Caterpillar engines, I have a any kenworth W900 of 94 or 95 i am not sure with that engine (series 60) and this is a great machine
ALL American manufacturers offered Detroit Diesel Series 60's from about the time the engine was introduced (about 1989) untill Freightliner (owned by Mercedes Benz) BOUGHT the Detroit Diesel Corporation. Freightliner now offers the Detroit Series 60 exclusively.
The Series 50 is identical in appearance (even color) to the Series 60, except that it has 4-cylinders instead of 6. It does not sound quite as smooth as the 60-Series, but with less cylinders that is to be expected. They both share many identical parts.
a 1693 CAT motor is all it is. Detroit copied the cat the only diffrence is the electronics ie.injection,and the old cat had a 2 piece head. Cat tried to sue detroit over this and a judge decided that they were too diffrent ie. (electronic), but what do you think judge Judy knows about engines? NOT SHIT!!!
You are SO WRONG!. 1693 Cat had 2-overhead cams, Detroit has One. Cat was mechanical injection with external in-line pump, Detroit is internal electronic unit injectors operated by the overhead cam. Both Cat 1693 and Detroit Series 60 use 1-piece heads. Detroit cam is driven from the front, Cat cams were driven from the rear. Detroit cam can be removed with engine in chassis, Cat cams can not. One BIG similarity-they both burn diesel! It's YOU that don't know s**t, but certainly THINK you do!
detroit engineered that engine from the ground up spent millions testing that engine and so on. Don't be mad because you love cat engine and Detroit came out with a new design that kicked cat's ass.
50-years ago they came close. Today Detroit Diesel is sold exclusively in, and owned by Freightliner Trucks and is, or is very close to being the number one selling heavy truck diesel in America!
But improvements have been made to the newer ones...maybe not the EGR or turbo part of it, but the fact that when Fuel gets into the base, you dont have to pull the head on a DDEC V as the injector cups are replaceable, as well as the head bolts. I can change a non egr turbo in about 1 hour finalized, but the newer ones take longer to diagnose, and to RE and RE and that is where it sucks. Better than ACERT though ;)
We have been able to narrow it down to the turbo on the DDEC V. You get wear in the hole that the pin goes through for the actuator for the VGT. It's where the actuator connects to the turbo it's self. Every truck we have replaced the turbo on that has the wear has fixed the cutting out and surging problem. This is after you check the air charger, EGR cooler, and all hoses and tubes for leaks. Then the Delta P tubes for plugged lines. There is no fix for the wear other than replace the turbo.
Looks to be a DDEC 3 as it doesn't have all the EGR crap that's giving us many driveability problems. We had a fleet of 20 with DDEC 3 60 series engines. Everyone was sold with 700k and up some close to 800k and only 3 of them had internal engine work and that was just cams. A few even still had the original starters.
A lot of people told me that the EGR messes up the engine it's self. They should of left the series 50 & 60 the way they were. The EGR mess up to series 50 badly. They sounded better. 6V92 & 8V92's should of never discontinue.
Not even the dealer have had luck fixing the problems. You'll check on the hoses and clamps and the air to air and they are fine. The EGR or the VGT will hunt back and forth. When driving when you grab the next gear and get back in the throttle it will cut out and then surge back to life. It's not fuel related. Sitting still with wife open throttle you will see the VGT vary a little.
I have worked all over the world, onshore and offshore, all oil and gas related in very remote places. The 2 stroke detroits are the only engines that can perform and are reliable.
I agree that the series 60 is a good engine. I most often see them in Freightshakers (Columbia and Century class) and Sterlings, which can make them a bugger to work on. Trying to get the rocker cover off when the back half of the engine is stuffed under the cowl will make you curse like a sailor. Can't forget the fuel lines that go to the back of the head.
You sould ride on a bus power by a diesel 60. My place of worship was blessed buy some new MCI buses and I belive they are power by Series-60. That engines rattel the floor of the bus it so powerful, and can get a 48000 to 54000 LB vehical, up to speed real quick!
AC Transit's MCI D4500s have the DD S60s in them, and they move like butter in Bay Area traffic and they are way quieter than the Cummins used in regular buses.
Hell they've added programs since I left about a year ago. Some of the new programs include Agricultural equipment and alternative fuels (biodiesel, E85, Hybrids)
Don't know about 10mpg... our M915A3 tractors (12.7L, 470hp Series 60, running DDEC III or IV systems) would only manage 6-8mpg, loaded and loaded. And we had more than enough maintenance issues with 'em, primarily bad lift pumps and injectors. Had one actually break the crankshaft, at the pulley/damper, and another crack a cylinder liner (traced to a faulty temperature sending unit, causing an overheat).
I made my living selling used semi-ractors for 39 years and I would rate the Series-60 Detroit the most trouble free engine on the market by a large margin. In USED trucks you get to see ALL the problems! Detroit S-60-best; Cummins 2nd best; Cats - Worst.
WHAT!? When I went to NADC, we rebuilt a 4 cylinder gasoline engine (which we ran) and the diesel class rebuilt these engines (which everybody had to run before and after the rebuild). I'm not sure why they would stop doing that. Really it's the only way to know if the engine was rebuilt right for sure. I'm sure the school thought that if this engine was to break then it would probably be 25 grand out the window.
Do you think these engine can fit in Transit Buses?

i'm not the only person thats had #5 piston issues with a 12.7. Search the net and talk to mechanics. Its a design problem of some sort. I've heard some had piston cooling through the rods , i haven't checked on that yet.
I loved the way it ran , when it ran. The area where the pin goes through the crown looks light weight to me. Thats where mine kept breaking
levisnteeshirt 2 years ago
The old 12.7 had the cast pistons, the problem with # 5 was stress on the crown causing a piston _ dome separation. the new design started with the mk series model. ok the mk bk, pk ect. all have a new alum. piston ,drilled rods for oil to cool the complete piston and skirt assembly along with oil squirters that bolt into the block also helping to cool the piston. the new engines from o7 and beyond have some of the same improvements plus more.

LOL you are among a lot of people who have tried to do just that, some big companies have won the battle, lets say Swift snider yellow to say a few. but the poor owner op. usually got it up the, well you know where. just get your hands on a DD15 that engine will blow your mind !!

i've heard some people tried to sue detroit over the piston deal ,,, its a shame really ,,, the 12.7 reminded me of the best truck engine ever ,, E6 350 mack , but with enough power ,,, it really was great when it ran
levisnteeshirt 2 years ago
You're definitely not the only one. The older detroits (12.7) had this problem and it was a piston dome failure, design flaw in the piston. I'm a tech at a freightliner dealer and we've done our share of repairs like that.

You talking about that blue silicone boot or the 45 degree angle fitting? Any truck dealer, shop, parts supplier will have the boot. I think that was a Garret turbocharger, that angle fitting should be able to be found at a Detroit engine shop or very likely a Freightliner dealer (since Detroit is owned by Freightliner).

I am glad to see NADC still exists. I graduated in June 1985. In my days there, the world was just beginning to try DDECing the two strokes. BCIII & BCIV NTC were hot, and Cat was cleaning up the 3406 for replacing 3408. That was a simpler day and time. No lap top was needed. Now Cat on-highway is almost over. Detroit, please bring back the "92's" and "71's". Cummins, I have lost "INSITE". I have to stand and think "B","C","L","M", or "X". NTC 230-475 used to work just fine.

ALL American manufacturers offered Detroit Diesel Series 60's from about the time the engine was introduced (about 1989) untill Freightliner (owned by Mercedes Benz) BOUGHT the Detroit Diesel Corporation. Freightliner now offers the Detroit Series 60 exclusively.

Ah man, I love this kind of Detroit Diesel engine video. Can anyone point me to a video of a Detroit Diesel Series 50 video of this kind?
StopRequested 3 years ago
The Series 50 is identical in appearance (even color) to the Series 60, except that it has 4-cylinders instead of 6. It does not sound quite as smooth as the 60-Series, but with less cylinders that is to be expected. They both share many identical parts.
JGMagoo 3 years ago
a 1693 CAT motor is all it is. Detroit copied the cat the only diffrence is the electronics ie.injection,and the old cat had a 2 piece head. Cat tried to sue detroit over this and a judge decided that they were too diffrent ie. (electronic), but what do you think judge Judy knows about engines? NOT SHIT!!!
thedieselDc 3 years ago
You are SO WRONG!. 1693 Cat had 2-overhead cams, Detroit has One. Cat was mechanical injection with external in-line pump, Detroit is internal electronic unit injectors operated by the overhead cam. Both Cat 1693 and Detroit Series 60 use 1-piece heads. Detroit cam is driven from the front, Cat cams were driven from the rear. Detroit cam can be removed with engine in chassis, Cat cams can not. One BIG similarity-they both burn diesel! It's YOU that don't know s**t, but certainly THINK you do!

detroit engineered that engine from the ground up spent millions testing that engine and so on. Don't be mad because you love cat engine and Detroit came out with a new design that kicked cat's ass.

DDEC III or IV were definetly good.
But improvements have been made to the newer ones...maybe not the EGR or turbo part of it, but the fact that when Fuel gets into the base, you dont have to pull the head on a DDEC V as the injector cups are replaceable, as well as the head bolts. I can change a non egr turbo in about 1 hour finalized, but the newer ones take longer to diagnose, and to RE and RE and that is where it sucks. Better than ACERT though ;)
daisyandsteve 3 years ago
We have been able to narrow it down to the turbo on the DDEC V. You get wear in the hole that the pin goes through for the actuator for the VGT. It's where the actuator connects to the turbo it's self. Every truck we have replaced the turbo on that has the wear has fixed the cutting out and surging problem. This is after you check the air charger, EGR cooler, and all hoses and tubes for leaks. Then the Delta P tubes for plugged lines. There is no fix for the wear other than replace the turbo.

I wish Detroit Diesel would build a V8 version of the series 60.
panamcunard 3 years ago
Looks to be a DDEC 3 as it doesn't have all the EGR crap that's giving us many driveability problems. We had a fleet of 20 with DDEC 3 60 series engines. Everyone was sold with 700k and up some close to 800k and only 3 of them had internal engine work and that was just cams. A few even still had the original starters.
whatihave2do 3 years ago
A lot of people told me that the EGR messes up the engine it's self. They should of left the series 50 & 60 the way they were. The EGR mess up to series 50 badly. They sounded better. 6V92 & 8V92's should of never discontinue.
metroktransit 3 years ago
Not even the dealer have had luck fixing the problems. You'll check on the hoses and clamps and the air to air and they are fine. The EGR or the VGT will hunt back and forth. When driving when you grab the next gear and get back in the throttle it will cut out and then surge back to life. It's not fuel related. Sitting still with wife open throttle you will see the VGT vary a little.

I agree that the series 60 is a good engine. I most often see them in Freightshakers (Columbia and Century class) and Sterlings, which can make them a bugger to work on. Trying to get the rocker cover off when the back half of the engine is stuffed under the cowl will make you curse like a sailor. Can't forget the fuel lines that go to the back of the head.

AC Transit's MCI D4500s have the DD S60s in them, and they move like butter in Bay Area traffic and they are way quieter than the Cummins used in regular buses.

Don't know about 10mpg... our M915A3 tractors (12.7L, 470hp Series 60, running DDEC III or IV systems) would only manage 6-8mpg, loaded and loaded. And we had more than enough maintenance issues with 'em, primarily bad lift pumps and injectors. Had one actually break the crankshaft, at the pulley/damper, and another crack a cylinder liner (traced to a faulty temperature sending unit, causing an overheat).
Alisterwolf66 4 years ago
I made my living selling used semi-ractors for 39 years and I would rate the Series-60 Detroit the most trouble free engine on the market by a large margin. In USED trucks you get to see ALL the problems! Detroit S-60-best; Cummins 2nd best; Cats - Worst.

WHAT!? When I went to NADC, we rebuilt a 4 cylinder gasoline engine (which we ran) and the diesel class rebuilt these engines (which everybody had to run before and after the rebuild). I'm not sure why they would stop doing that. Really it's the only way to know if the engine was rebuilt right for sure. I'm sure the school thought that if this engine was to break then it would probably be 25 grand out the window.
