Unloading A 1947 GMC with A 6-71 Detroit Diesel Truck From The Trailer

- This 1947 GMC Diesel Truck is being unloaded at the 2010 Truckin' For Kids Truck Show at Irwindale, CA. Some of the guys that had gathered around to watch and that had personal experience with these trucks in their day said that they were "all show and no go" and "that their bark was worse than their bite". That Detroit Diesel 6-71 did have a really nice bark, though!
This is a model ADCW-974, serial #112. When it was last a working truck in the 1970s - early '80s, it was owned by Bob Pielmeier of Camarillo, California. He pulled a refer with it, hauling for Alpha Beta stores. It was painted a light metallic blue then and Bob had a sleeper behind - which is why the normally rounded corners of the rear cab window have been cut out square and the whole thing enlarged a bit.
Thanks for all that good information about this truck. It's good to know these things about this truck.
@@espeescotty I've been compiling a National roster for the last 35 years of all these trucks that remain today, listed by model and serial numbers. In some cases, I know some of their histories, as well. About 1,200 were built from 1940 to 1949 and I've located/documented about 55 survivors. (I'm a life-long Southern Pacific fan too, by the way! Mark)
man what a beauty this ‘47 is and a tandem axle long wheelbase to boot.
When I was a YOUNG kid I remember a 51 GMC with a log frame and the driver was having to buck the clutch to get it up the hill. It had a 6-71 too but it needed a brownie box because it wasn't pulling much or up a very steep place. 2-valve head back then and it didn't act like there was much 'go' in it. I remember Winn-Dixie trucks with the 6-71 bus motors and the sure sounded sweet and those drivers would shift 75 times to go 10 feet. One of the MTM mixers I drove had a 4-valve 6-71 with a 9-speed overdrive Roadranger and it needed a 5x4 too. All right except in a tight place. THANKS again, Scotty! A GOOD find!
I'm 44 now, but I can vaguely recall this engine sound from when I was a kid, mostly from buses for sure. Unfortunately at the time when 2-stroke Detroits were common in a lot of things running on the road, I never knew squat about any engines and couldn't appreciate what I was experiencing first-hand. As I guess many people do...I wish I could peer back into my memories and watch them play out like watching TV, but with the knowledge that I have now. I'm sure I saw some neat things that are gone now, but I didn't know they were special at the time. At least now, thanks to TH-cam, I am dialed-in and my radar is fine tuned to that awesome 2-stroke sound and I know when one is lurking within earshot and I need to seek it out!
THERE you go! Once it gets ingrained it's there to stay. Terex/Euclid ran a pile of them as did LeTourneau but I haven't found much on his with sound. ut just looking at the 100 yard pan rig with all those V-12 gensets will stand the hair up! You could hear it for centuries! I'll be watching. And I like v-8 anything. E-9's and 3408's and Scanias. ALL good. C U, Scotty! Thanks!
First tractor trailer I drove was a 1951 GMC with an inline 671, 5speed with a short fourth and 2spd axle and a dead axle. Same cab as a p/u. Those were the days my friend!
sounds little like the green goblin
Love the sound of those Detroits!
Yes, They are very reliable as well. Fuel economy, not so much
That truly is the baddest truck in the land!
An idling and very low rev of a 6-71 is what I always think of when I think of how a diesel should sound.
Killer bad ass truck. Sorry ass pit crew!!!!!!!
Great looking and sounding old truck
Yes your right. After this truck retired it was sold to Lee Frowiss of Santa Barbara , CA I miss that old girl so much.
Many times I drove her up through 154 to our annual aths show.
@KTMlover525 I agree. Beautiful truck with an awesome engine and great sound!
Yes, that is correct. The lead tandem axle is the only one that is powered. Pretty common in that era as well as having no brakes on the front wheels.
I remember the flip control for front brake limiting,, I still think it's a good idea for snow or rain covered roads. All the trucks had that back then.
I remember some of the freight trucks had a sort of belt that could power the rear axle when needed. Also they had sanders in front of the drive wheels for traction when needed.
This was an ADCW-974 model so was dual worm drive originally, and also left the factory with front brakes. As it goes with trucks, though, things get changed along the way.
That 6-71 probably gets better fuel mileage than the Cummins or CAT in the truck that hauls it. LOVE the sound of a 2-cycle Detroit.
nyshortline not likely, its a 2 stroke. Uses twice as much fuel to get same horsepower rating that a 4 stroke does on the principle that it fires twice as much. Thats kinda what did these old Detroit’s in.
Sadly true.
If the 6-71 is kept at its narrow working revs, this is true.
Well, another sweet catch! That old GMC is a truck loaded with style, character and bling! Love the Buds on that beauty! You can sure hear it comin and goin! Wonder how long it took to get that rig looking that good?!
Thanks, I'm glad you liked it! This is a nice truck with timeless styling. And the 6-71 under the hood sure kicks the cool factor up by about 10.
Notice him wheeling the steering wheel around....my guess is no power steering. Way cool video. Thanks for posting.
Yup, it's an "Armstrong" steering setup. Thanks for the compliment.
Assuming that has a split manifold with each stack isolated from the other...? The 671’s sound unreal when set up like that!!!
Nope, watch the video - easy to see it has a single exhaust that splits to the sides under the rear of the cab.
Nice truck. Governor set correctly as it isn’t “lopeing”. Seems like an air tag axle. No buds or twin stacks on the 6 banger in the day. I owned a couple 238s. Allot of noise but not much go. Still a good looking truck tho.
Wow that's an awful lot of cook's baking that cake ..... Just gemme one good set of eye's who know's left from right and were good ..
The guy walking behind the truck has a lot of faith in those brakes. I wouldn't back that truck an inch with him standing back there.
Not wrong ol mate, that mob couldn't organise a nooky in a bordello with a fistful of fifty's
nice. i got a true dual international factory conversion in a '50 650 twin stick

I wish I could see & hear Your truck!👍🏽😁
This summer my friend who is a retired log trucker is giving me his ‘49 International Harvester LF log truck. It needs completely torn-down & rebuilt, so I’m putting a Cat 3406 in mine with a Banks power-pack & a fuel injection performance kit, then turbo-charge-it before I run twin exhaust down the sides of the truck.
Theres lots of custom work I wanna do with this classic, but it’ll take time. When it’s done though, this thing will eat pavement with an evil grin!😈
The DOT will get you! A 3406 will do it all by itself without the extras if it's right!
Had to do a pull up !
@espeescotty same i looked for so long to find my pete and im glad i waited!
Actually back then didn't the motors say General Motors Diesel on them?? I drove a REO with that motor & it looked just like a 671 Detroit
Love the ARMSTRONG steering. LOL
Yes, as a matter of fact, the engine in this one was labeled a General Motors Diesel, but the reason I chose to go with Detroit Diesel in the title was that the Detroit Diesel brand is far more familiar and specific to most people who know of the 2-strokes and might be searching for videos of them. Since this is a 6-71 in this truck, albeit with a different name stamped into the valve-cover, I went with the more widely known name.
Gotcha' I've only seen a couple with the General Motors Diesel name on them. No matter what I love the sound,, good video
My dad deove a 59 Jimmy for Mobil Oil,, I remember the sound of the engine not sure what it was labeled as, but sounded bad ass like that. LOL
Thanks again!
that's super awesome
what a scaredy cat driving the truck.i thought he would never get it backed off the trailer!
Well it is precious cargo but I dont think the 15 people telling him 16 different things helped any. I heard whoa whoa whoa a lot.
It catches on the J-brackets under the fuel tank and ya stuffed, I'd be goin steady to with a helpful mob of galoot's like he had hangin about 🤷♂️🤦♂️
@espeescotty im about to start a conversion. im puting a6v71 or 6v92t or 6v53t in a 78 ford f350 haha
Why hold mudd flaps ?? Dudes want ran over Ay??
At that angle, with the front of the truck so high, the flaps would hit the ground and the rear tires would roll over them and tear them off.
wooooow! nice lookin truck! id love to get my pete looking that clean.
@KTMlover525 Ha Ha! Well, enjoy that Cummins. I love mine.
I believe that one would be an ADCW974 or an ADCW954.
It's ADCW-974, serial #112. Don't let the fact that one of these has tandem rears fool you, though. Most are single rear 900s that have had a tag axle added. And this one doesn't have the original Timken suspension and SW-456 rear axles anymore, either. Though it would have been dual drive originally, it now has a tag/dead rear axle.
@@markandlinda2886 yep, I’ve seen a few 900s with an added rear axle.
@KTMlover525 Sounds good! You should make videos of the progress and put them on TH-cam.
they had enough bite to get the job done especially back in the day and even if they didnt their worth it just to listen to that evil sounding bark
6-71 had enough bark all the way to the 80s and 90s
Even today they will pull 70,000lbs just much slower than others today
With Dayton Wheels it'd be perfect!
with only one drive axle am i right?
Yes. Being a model 974, it was built with dual drive axles but these were replaced on this truck many years ago with a single drive and tag axle.
@6str8up I'd love to have a Pete! :)
Is there a build thread on this truck that anybody knows about,if can you please post it
No, there isn't. This truck has been continually running it's whole life, going from a working truck straight into "retirement" as a show truck, with just minor upgrades and new paint jobs along the way under several owners. It never really went through a major, one-time restoration/rebuild.
How to make a drama of unloading a tractor unit.
@KTMlover525 Congratulations! Who says you can't put a Detroit in a Dodge!? :)
by half way off he was likely out of air
@espeescotty me haha i love a cummins to much
@espeescotty well i would love too but now i cant i got a 2000 dodge 3500 for christmas :) haha
Never stand behind one of those coming off a trailer. Duh!
I was definitely worried about the "what if's" when I was shooting that that day! I'm glad nothing happened, but I was cringing in my head watching it.

Unimpressed.
