1978 GMC 9500 Detroit Diesel truck tractor Fruehauf trailer

[raginroadrunner]

flat land trucks...engine parts no longer available..EPA took them off the market as they polluted like hell..

[jmjfanss]

@raginroadrunner

Fuck the EPA.

[detroittwostroke]

@raginroadrunner Because so many Detroit Diesels were made, there are lots of parts available around the world. Also, Detroit Diesel will rebuild any engine, two stroke or four stroke. And as long as they are maintained properly, (standard maintenance, oil changes with correct straight weight oil) those engines don't pollute that much more than modern engines. In fact, because of their reliability, some models are still made for military use.

[raginroadrunner]

@detroittwostroke ...after 40 years in diesel engine business it is my understanding that the proplem is not in the two stroke exhaust, but in the blower box drains that runs out on the ground. I know of many rebuilders that won't touch them, Another problem was the runaway with the governor system, if not assembled and adjusted correctly they were dangerous.

[detroittwostroke]

@raginroadrunner You are correct. However, the engines could be redesigned, like the military versions that are still made, now with electronic control (DDEC). And I'm sure they could solve the oil drain problem if they wanted to. But I suppose the engines would still be too loud for today's standards.

[raginroadrunner]

@detroittwostroke ..used to work in the oilfields in Colorado..you could hear them old 8V-71's on workover rigs bellerin for miles and miles in the dark of night when they were working on a well....an awesome sound...in the trucks they had to be run wide open or not at all...I worked with a WW2 US Navy "Jimmy Diesel"..mechanic. He worked on them in attack landing craft during the war. He said that 'Gray Marine" invented the engine and GM bought them knowing the war was coming. A helluva man.

[detroittwostroke]

@raginroadrunner I, too, think these engines have an incredible sound. Every now and then, a Detroit will pop up in some older construction equipment. It is such a unique sound. Also, re-reading my posts here, my first post seemed to have a know-it-all tone, which I didn't mean. I'm only 20 and trying to learn (and teach) what I can about these old two-strokes.

[ke5hbd]

My uncle hauled rock with a truck just like that one in the early 80's

[MrEazyeaze]

if ur in or around tx ill give u 2500 for it

[MrRackensack]

1978? wow I always thought they were older. The one prior that used to carry the GM cars painted light blue By a carrier called Gateway Carriers* I think. After they stopped using them in the later 70s they went to the Brigadier with that same aqua blue.

[MegaZsolti]

Sorry Hotrodx199, but I think that is a 6v71 too

(but i am not sure)

[classicpower07]

This truck is a 6V-71.10 speed. It's For Sale for $2500

[27biggie]

2500 ill buy it if you still have it

[27biggie]

2500 ill buy it if you still have it

[pwarren1010]

Think she would pull the 53` 4 axle trailer around the landfill? Its at least 100,000lbs gross. I guess with the right gears it could do anything!

[AmoralEngineer]

@classicpower07 Do you know which 9500s had 8v71's and which had 6v71s? Or is it random?

[2strokedetroit]

@classicpower07 woah still for sale?

[nachos1990]

actually sounds like a 6v71 not a 92

[Hotrodx199]

That's definately a 6v92TA

[canadiantimberwolf1]

Hey Brad,any more pics of this old girl...I got a screensaver from your website and wondered if you could post anymore video and stills of the old girl...Oh by the way,nice job & great memorial too Jerry Reed wit the Smokey & The Bandit rig you've put together.

[chevy966]

im getting a 1977 but it has a 671 in it

[worldhoneymarket]

WOW! now thats a truck!!

My Dad's got an old 76 9500 GMC just like that!! I love that old vintage 2 stroke sound!!!! It sounds like raw power!

Great video man.

[TheSteamLocomotive]

Two stroke sound and when properly tuned and maintained these two strokes get four stroke fuel milage. They seem to have fairly clean exhaust when running properly too. EMD used this basic design on locomotive engines, after all they were both owned by GM once upon a time.

[railrunner2005]

correct and them 2 stroke SW1500 are still runnin today too.

[canadiantimberwolf1]

Hey Brad, you still got my 9500 around from when I get back too Canada or is she gone these days.

[classicpower07]

I still have this truck as of today.

[neurocytohemotoxic]

Cool truck. How much did it cost/

[DieselsAndDiodes]

cool GMC! This might be the first one I have see with DD 2-stroke.

[rich17279]

I love that truck, i'm in London, A truck like that isn't allowed passed the "low emission zone" :o(

[hhrtwo]

Brad...Wouldnt be interested in selling that 9500, would you?

Jim

[classicpower07]

Yes Jim,I would and for a small fee of only $2500 cash. It's an ex Mclean truck and it does have some rust,but very restorable.The engine is as clean as can be. I even have a Brigadere? hood you can have with it.

[hhrtwo]

Darn....Thats a good price, I'm looking at my map now to see how far apart we are.I dont have a trailer big enough to haul it, and I I wouldnt want to risk driving it..I am in in Indiana and have a friend Steve Shaffer thats a collector who might possibly pick it up...He runs long haul for Star..and picks up his antiques..possibly he could pick the GMC up for me.. I will follow up on this..

Thanks...Jim

[rich17279]

anyone know why tht sounds so much better than todays trucks? exhaust? 2 stroke?

[slooter3]

6v-53 or a 6v-71 or a 6v-92

[ClassicTVMan81]

6V-53 is ruled out (those were used in the lower-rated 7500s and 8000s); I have to say 6V-92T(A), even though the 6-71N seemed to be more common in the non-Brigadier 9500s.

A few Brigadier 8000s also had the 6V-53N (from 1978 to 1980) and the 6V-53T (from 1980 to 1984).

[blackmack1966]

hey isnt that the mack tow truck on the far left?? do you have any plans for that truck?

[Hotrodx199]

Sounds like a 92 series.

[alexthe22]

We want more.pls.

[MackAttack59]

does that mean the motor is like a weedwacker, you mix the oil instead of putting it in the motor'

[huppypuppy]

This is a 2 stroke diesel engine, as mentioned previously! This means they fire on every second stroke instead of every fourth (like on a 4 stroke) - like a four stroke diesel, the oil is seperate to the fuel! And they need a very special lubricating oil made specifically for them! Otherwise ya can lock 'em up good with sludge! Hence the name, "Sludge Pump"!

[rich17279]

Is that why they have that kind of rough sound to them compared to pther engines do you know? or is it just because they're old?

[huppypuppy]

rich17279,

What you said about the rough sound is right! Especially when they're started from cold with newly rebuilt injectors - you can hear the distinct idle clatter from the governor!

Joe

PS: Will send ya a link to another YouTube vid from a mate of mine who has a 1969 Kenworth LW924 and you will hear what I'm on about!

[raginroadrunner]

@huppypuppy ...Detroit said we could not run the 8V92 Silver 475 on 1540 oil. We ran them for hundreds of thousands of miles on it and never had a problem. Detroit wanted 40wt series one oil as they were concerned about ash on the exhaust valves.

[wyattjameson]

Hi.Can someone please tell me why this truck has such a peculiar sound to it?Im not an expert on trucks,but I remember these trucks when I lived next to a freight terminal and always wondered why they sounded different.

[bikerboy674]

This particular truck has an 2-stroke engine in it. That's why it sounds different then all the rest.

[Bkrites]

yea it has a GM Detroit diesel in it. its a 2 Stroke Diesel. you can hear em singin for miles

[yawotton]

you're right about that...that's the same engine that in some motor coaches right?

[Bkrites]

yea some older busses have 2 Stroke Detroits in em

[termite692]

These engins are called JIMMYS and first appeared in buses. Ever heard of the phrase"Run like a Greyhound bus"? I believe thats where the phrase was coined. I think the bus was a 4501 but not sure that was way before my time

[huppypuppy]

GMC PD-series buses had them - the 4104/4107 series, MCI MC-7/MC-8's and early Australian Dennings all had 2 stroke Detroits! Those were to name but 5 of those buses so fitted! My first run-in with GM 2-stroke power was an old Denning that our local bus company owned - had the rego # MO2822 and I wonder if it is out there still!

[termite692]

I knew I would rekindle the mind of an old bus enthusiast. I wonder if it's out there too.

[huppypuppy]

I hope so too - even if it doesn't have it's old number plates on it, would love to know myself! The Denning Dubbo Bus & Coachlines (the name of the company at the time, which is now Dubbo Buslines) had was a spare vehicle for when othe other buses were off the road being serviced! Bloody huge turning circle - couldn't do a U-turn at the end of one of our estates in one go - had to get her around as good as we could qand reverse back and go again!

[bwmuldoon]

@wyattjameson Detroit Diesel Engine is what makes that unique sound.

[JtsGreene]

@wyattjameson They are 2 cycles, blower scavenging diesels

[NTC335]

萌え☆

[poorawls]

i want one of those again jus for the sound

[punkasscracka]

This truck sounds just like that one truck in that movie Christine, where moochie welch gets dropped off at the underpass or whatever, I love the sound of that truck when it takes off and this one sounds just like it!

[BessieMorrison]

Love the sound of this Diesel.... Strong

[CWJacksn]

I remember McLean as kid! Thanks for the vid and thanks to everyone that's made a Detroit vid.

[12v71]

Very Nice Jimmy!!

[RDG484]

6V-92?

[nikeman910]

most definitely

[dieselquan]

Could you PLEASE make a long (ie, 5 or 10 mins) driving vid of this one?

Thanx!!

[dieselquan]

Great vids man!  Very nostalgic sound on this particular one! Is this a 6v92ta? Sounds like the older double-rear-axled fire trucks. How much hp/tq?

[MossyOak83]

yall need some straight pipes! nice truck!

[seashull]

it's the H model wrecker

[seashull]

what is the H model in view of gmc can't think of it

[DodgeRamit02]

awsome classic
