What should we do with a 2-stroke powered cabover truck? 🤔
EDIT: We appreciate the ongoing technical discussion about low ash 40w oil being best for these engines. Interesting stuff! Maybe we'll do a follow up video on that.
straight pipe tf out of it an full send down a street at the speed limit
Put about $250,000 US into it and give it to whistlindiesel
That engine requires a straight 40 weight oil, they do not like 15w40
Maybe restore the truck or use it as a tow pig for the fleet of vehicles?
@@alexhopkins3614 beat me to it
You fellers really gotta adopt the "dual wield" Cosby sauce method! Works everytime!
fuck yes i was thinking wheres the fucking ether
Peg!
A man that knows the Cosby sauce right there 👌
Fog it till she's ether-locking and then back it..... ah fuck, give'er both cans full tilt!
Yeah and if it catches on fire, you just piss it out and tell everyone the smell is from the rats.
Fuck me girls fuckin ZIP TIES N BIAS PLIES gets me hard ❤️
"Tough Times Don't Last Tough People Do" was the quote of the entire video right there How Ironic!
SAW ONE OF THESE HERE IN EASTERN CONNECTICUT 1980 ONE
STILL GOES IT WAS A TAN ONE NICE TRUCK BETTER THAN THE PLASTIC JUNKS TODAY
Just a note on the old Detroit 2 smokes.
If you're going to run it under load they need straight 40 oil. Multi grades will cause piston scuffing.
Ring up Shell for a barrel of straight 40. Yes they leak as much as they burn.
Man, what a struggle! He kept smiling and laughing though which was amazing!
Hey Rich, you picked the one diesel engine that can't use Rotella 15W-40. Those 2 strokes need straight 40 weight "low ash" oil.
I was thinking the same thing
I will third that motion
Wait really?
I'll 4th it. Straight 40 Rotella
I’ll 5th it. We use Delo straight 40w
New drinking game, take a shot every time you change the batteries 😂😂😂
You won't see the end than
I've always had an affinity for cabover designs for some reason. I'm also an Isuzu addict and have picked up a few NPR's relatively recently for the 4BD1T to resell. The truck is a solid little flatbed with sides so I've just been driving it around to pick up random stuff. It's funny how fast everyone around suddenly needs something moved when driving either the flatbed or the newer box truck. It's a whole new level of "the moment you get a truck every friend wants help moving their stuff."
Did anyone remember having an engine that needed 24 volt starter and charged with a 12-14 volt alt?
It is called a "series parralle switch. Alt charged 2 sets of batt at 14 volts. When starting circuit is engaged the switch opened and released one set of batt from charging and closed switch to make 24 volt for starting. Enjoy
I've seen a handful starter gets really upset when that bugger hangs on only on old fire trucks
Mercedes Benz little Service Trucks 809, 811 in Germany the UPS Rides These Trucks! These Trucks have a Relais under the Driver Seat.
Diesel Creek's Autocar has that setup too.
Yep, just threw away the thing, off of my 1986 KW.
Yes I remember the damn 12 to 24 solenoids. One of the worst ideas to hit the market. Nothing but trouble.
These are so cool! Rotobots, OXIDIZE!
On point sir!
Made me laugh.
11:20 can confirm that you have to wait for the truck to air up before the engine stop will work. Scared the piss outta me first time I had to reach in there and pull the rack closed by hand when I couldn't figure out why the switch in the cab wasn't working. 🤣
30 weight non detergent in those Detroit’s. No multi weight oil.
More likes!! they need to see this before they cause issues..
The correct oil to use in the old Detroit two strokes is 40 weight CF2 low ash. and it does have a detergent package.
@@johndonahue1935 I'm suprised Shell gave them the 15W40 for a 2 cycle Detroit.
They just supplied him the oil and asked him to do the vid he says at the start he bought it after their offer
Wrong, non detergent is to never be used in a 2 stroke ever!
where you say multi grade is acceptable, I can show you an example where it’s very wrong. The military has 2 strokes still in use, at one time they had a LOT. Well, Detroit specifically told them straight 40, and they ignored it for logistical purposes (the can’t be stocking lots of different fluids, so they stock 15w40 diesel oil, dex transmission fluid, 85w90 gear oil) and continue to run multi grade in their 2 strokes, and they fail with less than 10,000 miles quite frequently.
When we say a 2 stroke needs straight 40, we aren’t talking of “old school, non detergent oil”, we’re still speaking of a modern oil with detergents and such light years advances of 1960s oils, but it won’t shear down and destroy this engine like multi-grade will.
My friend, I am an Arab, I work in Turkey as a mechanic and I have good experience in restoring old trucks to their previous era, developing engines and adding an automatic gearbox
Hard to beat the sound of a straight pipe screamin' jimmy
2-strokes use straight 40w oil only, not a multi grade.
Was just about to post this, good catch
Yup I work on these engines every day. Big no no.
Yeah he is rocking the wrong oil. Sae 30 during the winter I there I’m assuming
Yes!
I hope he sees this
I just love your heart for bringing the dead back to life!! Tons of people would have given up almost right away. Same here! Great job!
4:46 and one ground going to… you know the thing 😂😂
Still the most efficient way to turn diesel fuel into noise.
Shells the best. Dads Jeep runs on Rotella and so does mine!
We have stroked 4.0L! They’re now 4.7L in-line 6s with side super charger. They’re our rock crawlers. Shell hasn’t let us down yet!
Great job man! 👍🏾
Finally after all you did, you make it run 👌🏾
That was a lot of patience of you trying to start that classic ride.
Congrats 👏
Lol! This was great, I’ve run 24v through an old heavy duty 12v starter before to get old/ cold equipment fired up…. It’s awesome how they suddenly crank like there’s no tomorrow!🤣🤣🤣 greetings from Scotland!🏴
Would be cool to see the truck taken care of or a Detroit build on the channel. The UA-cam community loves those engines.
All the old guys always told me to check the bunk in a cabover before tilting the cab. That way a CB ratio or somthing doesn't fall forward and break the windshield.
It's already broken.
Or last nights lot lizard.
I remember my dad doing that, in his case it was a thermos full of coffee. It went through the windshield like a bullet.
Even though cabovers are the norm here in Europe, every now and then, something will come flying out the windshield at the truckshops.
Back in the day I had everything secured so that thecab could be tilted. The cradle of straps I had holding my T.V. in place was particularly inpressive.
Brought back some memories. I worked a lot on 6V53's, 6V53T's and 8V71T's in the army.
Anyone struggling with a project or goal should watch this video. You are an inspiration to never give up.
“You know what? Let’s buy another one!”
now this was truly great!
i love the old jimmys and i used to drive a 78 astro.
im glad you got this old girl running rich!
save her!
not too many 2 strokes left!
great job as always sir! 👌
I once worked in the GM Truck and Bus plant where this truck was built. I think the plant was demolished a few years ago.
OMG, you just brought back many memories of my youth. In the '70s, I worked for a moving company to pay for school/university, drove a cab-over Jimmy just like in this video, with a screaming Detroit Diesel. Glad you found a red truck (red has more horsepower)!
I also use Shell Rotella T6 in my motorcycle, it is known fact that the specs for full synthetic diesel oil has the proper specs to run most Japanese motorcycles. Rotella is much cheaper than the synthetic name brands for motorcycles.
Rich, another fun video, thank you!
I use Shell Rotella in my car it's a old tired engine and it just loves the diesel oil and it makes me think I have good oil pressure LOL!
I love that 2 stroke sound - glad you got it running.
It’s just scraping the rust off the inside of the cylinders. Keep crank’n, she’ll go😂😂
ya just give her ALL THE BEENZ
Yeah. All it needs now is a good freeing off round town and youre all good to go again :P
Send it
Hey Rich , your perseverance to nut out the problem on the GMC truck is why you are a Good Mechanic
These are the jobs that I learn the most from. Love it.
You're the only channel I can watch a 35 minute video of lol
Might need to swap on an air starter, and clear out the fuel line. Other than that, killer Detroit content.
Air start for the win.
There is just something so soothing and relaxing about listening to a 2 stroke detroit diesel.
This was one of the most satisfying videos ive watched in awhile
I would love to see you guys fix it up. Maybe get the interior looking like it was meant to in 79. I wouldn't paint it though, i like the way it looks now. Those old Detroits sound so good!
IMO don't dump excess money into this thing, weld the worst of the rust, put in seats that has cushions, clean it up a bit, do what's needed to get it road worthy (and safe) and then thats it, use it for hauling heavy stuff now and again, and if a buyer comes along that wants to fully restore it = Sell.
@@ToreDL87 you sound like a quitter.
@@austinhales1807 the frame is a write off and there is no chance you can repair it with the rust situation. rather buy a truck thats salvagable then throwing infinite dollars on this rig.
given the condition of the truck it still baffles me they bought it
@@austinhales1807 ? I'm all for breathing fresh life into this truck, what about that is quitting?
I'm already being optimistic here, the 10-20k its gonna cost to make it ok'ish again can be spent elsewhere.
They know it, we know it, you know it.
What little I proposed is probably already way above and beyond what they have planned for it anyway.
Wrong oil, the two strokes require a CF2 oil which would be Rotella T1 SAE40 in this case....
Do you honestly think a Detroit cares? It should be happy peg leg isn't trying to start it!
Honestly, this is the first thing I thought of too. The Bus Grease Monkey would be disappointed.
@ Calvin Wright -
Keep her in the ketchup!.
Bus grease money disapproving noise intensifies
2 cans of ether later
What a Beaut! You can't beat the way an old 2 stroke Detroit screams.
These were among the nicest looking trucks ever to me.
This is my favorite UA-cam channel when it comes to automotive stuff I have learned so much from watching it keep up the good work
Thanks! Appreciate it
Great job keeping up with the gloves!!! Since your video where you talked about that I have been trying to wear gloves at the shop, my hands are constantly covered in 20-30 cuts and then they get filled with abrasive dust. Gloves are a bit hard to get used to though! Better than having to amputate a finger or even worse a hand because it gets infected!
Thanks man. I'm working my way up to wearing them more and more but getting used to it
@@DEBOSSGARAGE glad that finally found a set of gloves that works for you!
I bet your hands are feeling way better at the end of the day 😊
As a child of the 70s and 80s, I remember seeing all these old-school trucks on the highways. My Dad was a big fan of country music, especially trucker music. It's cool to see old trucks getting some love, even if they're not as efficient or comfortable as modern trucks. I work for NAPA, and the amount of Shell Rotella 15W40 I've sold (T4, T5, and T6) is insane! We had a stretch last year where T5 and T6 were backordered.
Everyone: “Starter fluid”
Me, an intellectual: “Cosby in a can”
@Alex Gutierrez it’s AOC?! All this time I thought it was a horse...
Cosby sauce or consent in a can
I just call the stuff CC. Canned Coercion.
You HAVE to use straight 40 weight low ash content oil in Detroit two-stroke engines. I like Rotella 15W40 too - but I don’t use it in my screamer. It will screw them up royally. Just a heads-up.
I think “Bus Grease Monkey” would concur…
More please! Europe runs cabovers. I was surprised to see almost every rig in Italy was a cab over and most of them were stunning. Please go forth with this fascinating Detroit powered cab over.
Before I retired in 2018 we had switched almost all of our old starters, that would give you a hernia, with new cast aluminum gear reduction starters you could carry with one hand. If only they had had them for the 45 years plus I was a heavy duty mechanic. I lost count of how many DD engines I rebuilt from a bare block and when you first start the assembly it looks like you haven't even put a dent in all the parts. I was so glad when they came out with the DDEC around 1988.
wow, sponsored by shell?? I cant imagine they need any help selling oil but thats awesome! Great video btw
heads up: Motomaster Diesel Oil is just Shell Rotella. Even says it on the bottle.
So is caterpillar branded oil for reference
I'd love to send a few bottles of each to a lab for a comparison test.
This has to be the most satisfying, dead to running video you have done !
Great video, showed us your wins and failures in order. great demonstration of process of elimination. awesome stuff fellas!
Pretty sure that engine has a tight spot due to a spun bearing or something and that's probably why it was making that knocking sound when you finally did get it running........
Knocking and white smoke, a stuck open valve, common problem on an engine that's been sitting many years, not to worry the piston will push it back out of the way.
Sometimes pull starting is your best option. Thats' what I do... get that engine spinning.
Like a lawnmower ?
@@Hanzyscure No. he’s talking about pulling the whole truck and then putting it in gear and dropping the clutch. That way it can spin the engine over much faster. Starter will spin it at a few hundred rpm. Pulling it and dropping the clutch can spin it at a thousand or so rpm.
I'm 22 and after I crawl under the car for 14 hours il be sore as it gets rolling over slow in bed and the whole works this guys gotta be close to double as many moons as me and crawling under there with enthusiasm. I respect it
Gotta love the sound of the old 2 stroke Detroit's !!
Shell: What's it cost to have you try to run some old junk on our oil?
Rich: A pallet of that oil will do!
Thumbs up for Big Shiny Tunes 4!
One of the best CDs to grace our car stereos!
Great persistence there. Superb sound when she fired up.
The timmies got me.
and my boss talking constantly about your vids.
I used to sell parts in the early 2000's. It seems to me that we stocked all of 2 starters for logging trucks and equipment, 12v and 24v. The only other difference was just the clocking on the nose which was pretty easy to change when they were fresh from Dixie.
Runaway cabover blows hole through shop! Sounds like UA-cam gold to me. Surely that would pay for a new door and a few cinder blocks, eh?
What a great video. So satisfying when she lit up. Can’t wait to see what you have in store for her Rich.
Awesome! You guys are Pros. Never give up. From a former mechanic.
Do raccoons like exhaust manifolds?! 😳
My only conclusion to it wanting to spin fast and then stop... I could be wrong though
In Canakastan it’s pretty common!
Not sure about raccoons, but mice love those pipes, and mufflers
@@DEBOSSGARAGE Family lore from waaaay back in the day (probably 1970s, before my time) is my Grandpa had a brand new 8v in the shop that would just barely crank fast enough to get running and then ran like garbage once it did. One of the exhaust manifolds was completely obstructed from the factory. They never cut the port holes in it. Took them like an entire week to find that problem.
@@bertgrau9246 Bought an old international diesel tractor. Ran ok at sellers. When I got it and changed fluids and filters, I struggled getting air filter cover off. When I did it was solid mouse nest around entire barrel of the filter. Not sure how it even was breathing. I mean like packed in hard mud these mice did this. She definitely felt differently after the clean up and new filter
Gotta use straight weight 30 for cold or 40 for warm or otherwise you’ll break your top two compression rings on your pistons and wear your cylinder walls faster.
Just wondering why would a multi-viscosity oil that is within the reccomended range not protect the engine better? Granted it is an older engine.. but wouldn't the same theory still apply?
To make it simple and not write a paragraph 2 strokes have a power stroke in every stroke and multi vis oils don’t have enough time to recover between strokes making the oil thinner creating more heat and friction creating more wear in your cylinder walls and the heat makes typically the top compression ring extremely brittle breaking it quite easily.
@@benl1053 interesting. It just seems odd that something like a 15-40 would not do the same job as a 40. But like you pointed out, a 2 stoke of larger displacement is a different ballgame. I'm no expert but a multi viscosity oil's advantage is that it performs like a lighter vis at cold temp, yes? If that is correct, is it that property which makes a multi-vis have a longer recovery time as you put it when compared to the single viscosity of same weight? Genuinely interested and trying to wrap my head around the concept is why I ask. Thanks!
Awesome video! Love those old cabovers and they are getting harder to find! Really good content... cool background music too! keep them videos coming!!!
I grew up in one of those trucks. My dad owned one. When you showed the drivers compartment it brought back memories. Also who knew you needed fuel for the motor to start
That was real fun. Hope she get's some needed attention and a matching DG batch like the c10. Would love that.
Love the old Detroit 2 strokes lol Love the buzz
Yek yeeees man!!!! You did not quit!, I was just waiting to hear it purrr. Great job! 💪🏽👍🏽💪🏽👍🏽
You went through a lota work and never tried to pull start it at 50 kph? You did finally get it!! Fun times. Thanks for another video :)
that first bit, lets buy another one had me laughing hard, do love this channel
God I love this truck. It reminds me of the old International roll back that my pap used to haul equipment with. Like 80 hp with a two speed rear single axle. I would sleep in the floor boards during winter to keep warm. :) the 80s were dangerous. Lol
The 80s were the best of times for me.
I had to leave my '72 Chevy Titan in Georgia when I moved to Arizona. I gave it to a good friend. I hope to find a cabover here in Arizona that I can bring back to life. Nice work!
Nice!!! Love watching wrenching on old trucks
I re-brush the starters on all my Detroit’s any they’ll spin better than new
Surely sometimes you get an armature that has a dead spot right?
@@44R0Ndin armatures rarely burn out normally its brushes or solinoid that go, ive only seen 1 bad armature and thats cos it went swimming in salt water... did not like that at all
This man loves his job
Is that “rattling” in the valve train? Yep once you got her spinning fast and it did not light, had to be fuel...Lots of work having that much fun, thank you for the entertainment.
I love the sound of a Detroit .
Them Detroit's just sound so good and the dashboard looks cool love all the old truck's 👌👌👍
Love how filthy Rich never gives up!
Optimus brine. I fawking love it bud.
I drove those babies back in early 80’s when I worked at Hertz rentals. Great tractor to start driving on.
That laugh of “helplessness,” been there done that
USCG is still using the 6v92t in the 47' motor life boat, thirsty, but they are tanks.
The Army still uses the 6V-53 T & 8V-71 T in the M113A3's and M109A2's-M109A6's,the 8V-92 TA's aren't as common anymore in any Oshkosh trucks,all now use Caterpillars.
Best year ever.....especially Valentines Day that year....ugh I'm old.
My father owned a 74‘ Jimmy Astro 95 just like that. Beautiful rigs!
Awesome looking old truck....love the wide tires and the cab over vibe its got
Love watching your show I think it’s hilarious every time you tinker with something it fights you tooth and nail I feel your pain bud every time I try and tinker
The drag line sat for 20 years and fired right up lol. Was expecting the same with this but no....
i love these us cabovers, if i was ever to import anything it is something like this. love your videos
I saw a GMC Astro in the thumbnail, and then I saw the intro, and I immediately subscribed
You had me at “Lets buy another truck.”
Love the cab over. Can't wait to see it again. It would be a cool toy hauler.
Had the same thing happen to a Group31 Napa battery we had at work. Threw us all for a loop
I used ride with my dad in a GMC Astro just like that. It was my favorite. That was back around 1970.
Its like im looking at my late cousin who i work for....😇👌 Miss all this.. bless you man..👍💪
Yeuss a Detroit! Thank you more please!
The hole truck including the alternator is 12v system put uses some relays and black magic to get 24v at the starter just why cranking by rewiring the battery's to 2 parallel in a series for 24volts
That is common but there would be a dirty great big change over soliniod near the battery's amd extra battery leads
@@fowletm1992 yep and it was a parts truck in a field somebody likely took it
The youtube captions when she finally starts "[Music]" haha
Wow that was really satisfying to see it start!
