I miss the sound of these engines, when I was a kid they were very common on everything from trucks to buses, these days you don't hear them too often.
These old detriots will never die. I have a 6-71 in my old Terex wheel loader I use on the farm. You're one heck of a driver too, keeping her revved up just like Detroits like to be. Lovely truck, thanks for sharing!
FYI... Just from family that drovve A DD 6-71s and 8v71, there is no engine that could out perform the meager specs of these working class engines. If you didn't mind going deaf along your journey... When I was a teenager my pop stopped home for his dinner break on his way to Minneapolis out off Chiago for Sears.... My brothers and I were out riding bikes and I knew I loved the sound of a 6-71 then... I was hooked
Not sure what you mean... the larger cousins made by EMD were used in hybrids - namely diesel-electric locomotives. And in fact the 6-71 was used in a few very small diesel-electric switchers. Locomotives went to hybrid technology for the exact same reason cars did - fewer mechanical transmission components and better fuel economy. They just did it in the '30s whereas cars didn't do it en masse until the 2000s.
Oh man... I had almost forgotten just how good an NA Detroit Diesel sounds....... I love turbo whistle, but it kind of mutes the guttural growl these engines have NA. I got to hear a 6V53 in person on an ex-military generator that had enough power to light up both of my uncle's chicken houses, and all three houses on his property, with room to spare. The lights in the chicken houses were brighter than being on the grid....... He would do a monthly load test on generator. It was glorious. Edit: I must add, when I say he powered both chicken houses and 3 actual houses, I mean this as in powering the most critical things. For the houses, back up power was its own thing and ran just important things like refrigerators and such, and the living rooms had power as well. For the chicken houses, it ran the egg cooling room, the watering system, and the lights. If eggs needed to be gathered without power, it was done the old fashioned way, get them by hand. The generator would also not power the cooling system for the actual chicken house unless it was absolutely needed on the hottest of days.
@John Dunlap if only you knew how a blower works (air scavenger) its just there to bkow out the exhaust so the engine doesnt choke i habe many Detroit's. Blower doesnt ad boost. So yea NA
John Dunlap it’s more like a fan it just blows I think I heard somewhere that it makes like 2 psi so not really worth mentioning but like the other guy said it’s just blowing the exhaust out of the cylinders
Thank you so much for giving me a ride in the old Brock. Brings back memories of when I worked for Alex C. Smith Inc., in Akron, NY back in the late ‘60’s. It’s been a long time since I’ve looked out the windshield going down the road in a Brockway with a Detroit in it. When I started with Alex in the summer of ‘68, the first tractor that I ever drove was a 1957 Brockway with a 6 cylinder Continental gas engine with a 5-speed & 2-speed rear axle. Thanks again...
I often see a lot of hate thrown at the 2 stroke Detroit Diesel engines..... I have never understood why. They are not the most powerful engines on the planet, or the cleanest, but they work, and just keep going even when abused. And, when rebuilt and tuned well.... I know these engines are still not the most power or cleanest engines on the planet, but they can be a lot better than they were. Diesel engines just rock, and get too much hate these days by people who do not understand them.
I agree. However, remember this is a '65 Brockway. It's not new. This was a '94 F1 Ferrari. Not new, but incredible...ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M1InrgZiv30.html
I grew up riding with my dad Diamond Reo long nose bench seat sitting oround shift racing trucks out of tollbooths I could speed shift that ole 238 10 speed great memories thank you!
When I was a child, the first time I rode to Minneapolis out of Cicero il in my dad's ol #341 I was hooked.Sears catalog freight. A 6-71 backed w a 10 SPD Fuller Road ranger. 40' drop deck Great Dane. My pop got ridiculed in truck stops by owner/operators. He always said "I'll compare paystubs with you any day " he raised 8 hard working children off of his check. The first time when my pop pulled up to the curb w that 9500 GMC the sound and smell of that screaming 238 had me. Whoooo
My father drove truck all his life and he had a GMC crackerbox with the 6-71 in it then he bought a '69 Kenworth K100 that had a 318 Detroit in it. Love those old Detroits.
My dad had a single axle just like that for mobil Oil back then. He would go from Norwalk Ct to Buzzards bay /Cape Cod Ma. It was an overnite trip for him as I-95 ended in New London Ct. On my last job Cape cod from Chesire Ct was a 3 hr trip. 2 stops & return in 8 hrs.
I found it interesting that the speedo is in the middle of the dash & the tach was behind the wheel, as if they purposely set it up for drivers to float the gears.
+Tap Dancing Crab Demon Compared to this Volvo 780 I am driving with all the creature comforts of a condo, the turning radius of a Pinto and A/C to boot ( did I mention it has an Ultra shift +? 😉) this Brockway is back to basics. And no doubt it will outlive all of us.
Reminds me of when I was a kid there used to be a 67 White 7000 cabover that had the 671 in it and it had that "sound". Sadly when I got old enough to find what happened to the truck I found it in the owners yard, the cab is pretty well smashed, the frame is buried in nearly 4 feet of mud from flooding to the point where you can almost walk into the cab from level and it was left with all the windows down. I was able to retrieve the air horns off of it and when I am doing redoing my 74 Ford I will have the horns on it from that 67 White.
@Reverend Krieger Durden Tyler sr Hopefully the end results will be great...right now I'm looking for a new fuel filter system then we want to get oil going to the turbo then get air from the turbo to the blower...then put our new rebuilt radiator on ...the list goes on ...wish us luck...Thanks for commenting...
My brother had a 1960's yacht with 2 6-71's. I still have the Navy overhaul training manual. It's a hard bound college book showing everything there is. lol The 71 series meant that each cylinder was 71 cubic inches. There was the 53, 71, 92, *102?* i forgot, (too lazy to google it lol). The 8V-71 was a 318 HP and so was the 6V-92. Take 2 cylinders off the 8-71 and the 6-71 (40 HP per cyl) is how much HP? Maybe a 230? The loud raspy spot about 1600-1800 is that power band like a 2 stroke motor cycle. Plus there are 12 impulses where other motors have 6. In the power band these things could pull almost anything. They also would cruise across the desert at 2300 rpm's. Man they were clean burning when you were highballing. It was the smoke at mid range acceleration that killed them with the EPA :(. I'm a Cummins man per sei, But I loved the 2 stroke Jimmy's.
David Vermillion hey thanks for that. another little story is I was on Interstate 5 at the Buttonwillow rest area and I heard a diesel pulling but when I walked out I could not see it yet it was still there idling. all the sudden this chick comes out looking like a Montana plowboy I was walking towards a 1987 International Pickup the last year they made. so I kind of like quickly up behind her and said hey what's under the hood and she opened it for me. and there sat a 3-53!!! if I remember right it had a 5-speed Allison in it that would be comprable to what the FL70's had. being a 2 stroke 3 cylinder it sounded like an inline 6 diesel sitting there idling and had such a deep throat sound it was amazing. if I can ever find me a 3-53 it's going straight into my 64 Chevy pickup lol
Wow just wow. 3-53 can really scream! I would have loved to see that. Hope to one day cram a 6v53 in an F350 one day. It don't make the HP a modern pickup does but it can make the torque!
Being British,I first heard a Detroit powered truck on Ice Road Truckers on TV. In certain episodes there is a driver called the King of Obsolete who is featured.I enjoyed hearing the sound of his Detroit powered Ford truck driving up steep hills,it sounded very impressive. The truck in this video sounds great too.
Ah yes. That was of one the few trucks the producers saw fit to leave alone in regards to engine sounds. Many of the other trucks engines were dubbed over for God only knows what reason. That being said, they still turned the volume done. Let that Detroit sing! No need to mess with perfection
I am surprised that Britain's own Foden two stroke didn't get your attention first. I've always been a fan of the Detroits, but when I heard the Foden I thought how it sounded like a much smoother, more refined Detroit 6-71.
These engines are unstoppable. I have experience with them in the marine environment. They leak oil like crazy, but who cares? It's a shame there's no easy way to clean up the emissions of a 2 stroke Detroit to keep the EPA happy. They were fantastic!
They could probably have added catalysts for NOx and Particulates and kept them going for awhile, but they are expensive and other engines initially did not need them…
I have to hand it to old truckers who ran 2 stroke Detroits and are now suffering hearing loss. Kind of glad majority of trucks are 4 stroke diesels. Was beside I think a Kenworth K100 COE with an 8v92 and the guy decided to run his jakes on the freeway...lost my hearing for few minutes...considering it was straight piped.
drive them long enough they get real quiet. you get deaf so you cant hear period. they had a 3 cyclinder diesel put in a farm tracter after running it all day you listened to the echo and ears ring for the whole night
in a f350 the clooest ull get is a 6v53 shoe horned in and ull have too beef up the front end...the 6v53 weighs 1500 not inculding the turbo...it might be more then that but its been done before just look it up on youtube....still have the same great nose just smaller and its governerd for 2800
Thanks for the reply. I'm surprised to hear there is more than 1 still working around here. I don't have any distinct details on the truck to identify. I've seen it on Quaker road a few times and it's always "omg there's a Brockway" I'll have to overcome my shock next time I see it and make note of details.
I was wondering what kind of tranny was in that thing till I saw the shifter and knew there were a lot of gear skipping going on at first. I drove an IH mixer with a 6-71, 4-valve and a 9-speed o.d. box for a long time. Tough old truck but wished it had a 13-under or a 5x4 because it needed a lo-lo gear. Good setup there but he needs some weight behind him. No much but some.
I bet! The mixer just had walking beams and maybe some rubber pads, no springs. You saw a rock in the road the size of a golf ball when empty you gritted your teeth and knew what was coming. BLAM!
@@kylemaslyn3836 The DOT here had some IH tandems with a Cummins and two speed REARS! They stayed together but with a tandem it'd sure be interesting if one shifted and the other didn't. You could hear them grinding/whirring all the time. Maybe a 5-speed main box. I was too scared to even look at it, being afraid I'd be held liable for understanding something about them.
Yes it is 2spd rear. 5.60 in low and 4.11 in high. with a T-905C fuller main box. I am going to change main to a T0-905C. I can run@ 65mph now @2250, But want to gear higher. this should take me around 72-74. Also you can hear the synco is going out between 4th and 5th. The reason for the grinding between 4th and 5th. Thanks for all the comments
