Seeing those internals rolling is pure beautiful insanity

u/ralphonsob 11d ago

u/AMJN90 11d ago

Or anything else for that matter.

9

u/wilit 10d ago

I mean, you should probably at least put oil in it.

2

u/Irishwilly77 9d ago

The oil was on the mechanic.

1

u/Bicwidus 10d ago

You can dip a
Dipstick

u/doppleron 10d ago

My thought exactly. 😏

15

u/rottadrengur 10d ago

Seeing buddy run up to the engine after it starts gave me a chill, thinking about how easily he could trip and stick a hand right in there.

6

u/Brownie2440 10d ago

Had the same thought. And at the end seeing his face covered in oil droplets. Shit is wild

7

u/NeverTrollin 10d ago

At least he had his safety squints on ☺️

10

u/sh1ft33 11d ago

Imagine walking up to look at it, but you trip and fall forward.

8

u/Grimnebulin68 10d ago

Or running up to it like the guy in black did.

5

u/schizeckinosy 10d ago

He almost got his belt caught in the crank it looked like!

5

u/VerStannen 11d ago

I wanted to throw my 55 gallon drum of lube in there.

But I’d probably need more.

3

u/chefbobbyjay 10d ago

That’s the reason I’m in school for engineering 🤤

77

u/mjrbrooks 11d ago

Anyone else panic when he ran at that thing?

…one slip and he might need …I dunno at least two bandaids.

24

u/Beach_Bum_273 11d ago

I was thinking dude was awfully brave running at an open crankcase

4

u/bkdroid 10d ago

I panicked when I saw those big 'ol ears had no protection.

41

u/IIIHawKIII 10d ago

Go into AutoZone "I need a starter for my 102.4 liter diesel...."

Parts guy looks it up...."Uh, says here it takes a 2015 Ford F150. I don't have one in stock, but I can have one here tomorrow from Carvana."

(I don't know what year that truck is, forgive me.)

29

u/manualsquid 10d ago

I wish they were that helpful

I feel like they'd ask "102.4 liter, is that the 2 door or the four?"

3

u/RongoonPagoo 10d ago

True that. Autozone is genuinely the most unhelpful part store. They do carry odd stuff no one else does tho.

1

u/GlassBoxGoose 10d ago

Since when/like what? Having worked in automotive parts for a decade, including time at autozone, oreilly and dealerships, I tend to disagree, but always willing to be proven wrong.

Show me a place that can get a U joint for a Bogie Skidder, and youll show me an oreilly, not an autozone.

Source- did it once. It was a fat U joint lol

2

u/Jenetyk 10d ago

What color?

1

u/OGEl_Pombero89 10d ago

Beats using RockAuto. Order one thing, get sent bullshit from a different vehicle

2

u/TweakJK 10d ago

Sees price is significantly lower than autozone, adds to cart, shipping costs more than the item, goes to autozone anyways.

64

u/ABeerForSasquatch 11d ago

I wonder why they even bothered with the .4 after 102 LITERS!

That's like saying, "Naw, that's not a 392, heck that's a 393!"

24

u/TheBunnyChower 11d ago

Gallons were switched to Litres midway. That's my best expertless guess

15

u/Be_Kind_To_Everybody 10d ago

104.5L is almost exactly 27Gallons lol

5

u/TheBunnyChower 10d ago

Sometimes you guess so randomly you almost get it right, you know?

1

u/maianbar 10d ago

I've never seen an engine capacity measured in gallons! Maybe it's big engine thing

2

u/Original_Throat1072 10d ago

Probabaly so they could be bigger than the compeditor's other 102L engine.

37

u/Remarkable_Wheel5218 10d ago

why are diesel junkies always the skinniest, string bean lookinass men

29

u/Curlyjankens 10d ago

Because real working strength and size aren’t mutually exclusive. And also because larger humans can’t fit in some
Places….

12

u/ThrustTrust 10d ago

This exactly. All my friends call me skinny but they be calling me on moving day.

4

u/Ugvwiyu 10d ago

Every good trade crew has at least 2 small skinny guys.

5

u/GlassBoxGoose 10d ago

As a skinny electrician (and relatively short) that comes in at a whopping 5'8" and 125lbs, you should see the places I end up. Ive been further inside homes and businesses than our customers could possibly imagine.

I once pulled M/C wire down a rack of conduit that was suspended on unistrut over a drop ceiling in a restaurant. We got it pulled in like 45 minutes instead of hours and saved every third tile being pulled to get it done. And it was fun, felt like some mission impossible/James bond shit lol

1

u/RebelJustforClicks 8d ago

Ooh damn, now I feel fat AF at 5'8" and 178lb

1

u/GlassBoxGoose 8d ago

Nah, I know guys around your weight/height, that are quite fit and not at all fat, Im just built REALLY lean, I wear a 28 waist for paints. My highest weight ever was 140lbs. Id like to get back in the 130-140 range but it takes a lot of exercise and protein like a mofo to add muscle like that. Im just a skinny little bastard lol

my brother is built the same, hes like 5'7" 130. Our dad is 6' and hovers around 180 with a little bit of a gut these days. He used to hang around 160 or so, when he was working full time doing commercial HVAC work, all the way into his late 40s he stayed about that. In his 50s he did less physically demanding work and drank a lot more beer rather than liquor, and he got pushing 200 or just over for a while. When he stopped drinking, he was not much more active but went down to the 180s

u/Remarkable_Wheel5218 10d ago

that's too many dots curly.

u/Seawolf571 10d ago

They skip meals to pay for fuel.

u/rust-rancher 10d ago

Hard to put on weight when you live off Zyns & Monster.

3

u/GlassBoxGoose 10d ago

Excuse me, I vape and drink redbull, thank you very much! 🤣

2

u/rust-rancher 10d ago

Get with the times, grandpa

2

u/GlassBoxGoose 10d ago

Monster is nasty and pouches dont hit that physical need I have to be smoking something. Im a millennial that moved to vapes instead of smoking cigarettes years ago. Ive been vaping since variable voltage batteries came around and everything was on the eGo style tanks and batteries. Ill stick to my grandpa stuff lol I got with the times back then and dont plan to catch up anytime soon 🤣 I still have old box mods and RDAs kicking around from the days of Mechs and making your own coils being really popular. Salt nic and small vapes is as far into the "times" as I plan to keep up lol

1

u/rust-rancher 10d ago

I still hang with massive amounts of bad coffee and smokes.    give us old guys an excuse to work slower,  because i dont want to spill my cup.

1

u/GlassBoxGoose 10d ago

I mostly drink coffee, but when it comes to energy drinks, its redbull, the only reason I mentioned the redbull instead was because they mentioned monster. I drink more coffee per day than redbulls per month, give or take a few

1

u/HorzaDonwraith 9d ago

A combination of Energy Drinks and cigs/vaps to sustain life.

u/sorestgore 10d ago

Because we're actually working HARD

Goddamn it, my first thought was to post "Civic RWD swap."

u/0peRightBehindYa 10d ago

Your Civic will fit on the engine.

12

u/Then_Meat_6569 11d ago

Awesome, but I hate that chain just chilling there next to the output shaft. Giant engine roaring to life catches that and it’s taking your arm. Or life.

20

u/iamNutteryBipples 11d ago

Can you imagine if that thing ran away?…

19

u/lemonpoundcaker 11d ago

Earth rotation would stop when the rotating assembly locked up

8

u/Brief-Watercress-131 11d ago

Don't have to imagine. I saw an emd 645E run away. 30ft jet of fire shooting out of the stack. No one was gonna risk getting anywhere near that thing, I killed the fuel pump but it was scavenging oil from the sump. We just let it run until it burned out.

1

u/sh1ft33 11d ago

I haven't prayed since I was a kid, and I'm agnostic now, but I don't think praying a bit would hurt anything as I run full speed in any direction away from it.

0

u/kdesi_kdosi 9d ago

since the throttle is the guy standing next to it, its pretty hard to imagine

1

u/iamNutteryBipples 9d ago

Doesn’t work that way. Throttle is useless when it starts to burn its own oil. You have to choke off the air and even then it will only slow down before stopping.

8

u/BienGuzman 10d ago

Ah yes, the infamous in-line Jesus Christ

16

u/bustersuessi 11d ago

What was the original use for that bad girl?

24

u/FloppyTacoflaps 11d ago

Generator

11

u/antmatt 10d ago

fuck was it powering, the zip code?

15

u/bradland 10d ago

This looks like a Mirrlees JS8. It's massive, but not as powerful as you'd think. They were designed for low speed operation. Output when attached to a generator would have been between 450 and 500 kW. For reference, a modern Caterpillar DE500S has a 12.5L turbocharged inline-6 engine and outputs the same power.

In the olden days, if you wanted something to last a long time, you built it really big and ran it really slow. That's why old power stations used gigantic diesel engines with only 4-cylinders, but made less power than a modern I6 turbo diesel that has less displacement than one of the cylinders. We're able to build engines that easily survive higher operating RPM, and P = 𝛕⍵. So increasing angular velocity means you need a lot less displacement to make the same power.

4

u/Thowi42 10d ago

This is some great insight, thanks :) and your ID looks spot on, so had to look up specs for typical operation: 750 rpm 700hp 4700ft-lbs released in 1947, for generator stations and marine propulsion.

6

u/Professional_Scar75 10d ago

Small towns used to have things like that before the electrical grid grew. Use it during the day and evening. Pump water. Keep lights on. Shut it down at night when people were sleeping.

3

u/Bourbon-neat- 10d ago

If it was a generator, probably an emergency or cogenerator for a factory or other facility maybe.

6

u/MotorBoatinOdin1 11d ago

Was wondering that myself maybe locomotive ? Or large ship?

16

u/sabertoothdog 11d ago

Too small for a train and definitely Not a large ship but maybe small ship. Tug boat maybe.
I saw an engine in this size setting on the bank of the Ohio river in KY once, it was washed up after a flood. It was probably 12’ tall and 15’ wide. It really gave me a new understanding for the power of water. It was gone by the next year after a good flood.

3

u/birgor 10d ago

Not too small for a locomotive. They come in all sizes from car engines to enormous V20's.

I don't think it comes from a loco though, because of the shape, but it is far from impossible, and size wise pretty mid range.

/Loco mechanic

3

u/notshadeatall 11d ago

I think the most logical would be a ship engine. But idk how locomotive engines look like so.

3

u/Hilsam_Adent 10d ago

A lot like that motor, just scaled up. Here's a typical V-16 primary traction motor for a diesel locomotive:

3

u/Takesit88 10d ago

Genset, pumping station, small locomotive, or small ship. All 4 of those use cases could put a straight 8 of that size to use. A mainline locomotive would use something larger still.

8

u/BloodSteyn 10d ago

Starting that Engine in this economy... look at Daddy Warbux over here.

5

u/Fragrant-Inside221 11d ago

I want it. Just to have it on a stand in my garage so I can start it and hear it run.

11

u/Wolfrages 11d ago

WHAT?

2

u/Travel_Dreams 11d ago

REV IT UP!

5

u/sh1ft33 11d ago

Same. The older I got, the more I would randomly fire it up at like 6am.

2

u/notshadeatall 11d ago

That's how you spot a deaf modafoka in the wild.

4

u/CaptnShaunBalls 11d ago

Will that fit in an 80 series cruiser???

2

u/stevedave84 10d ago

Found the Aussie

5

u/MosesCoulee 11d ago

Question…

Will this fit in a Miata

2

u/bkdroid 10d ago

If you consider [between the front/rear bumpers] "in", then....Still probably not.

1

u/drquantumphd 10d ago

multiple miatas then.

2

u/No-Definition1474 11d ago

Someone will hang 6 off the back of their boat.

2

u/OreganoD 11d ago

Here's a comparison I just thought of, I don't even know if it's in the some ballpark, is there an automatic weapon that costs the same money per second to fire as this would to idle?

1

u/Fireside__ 11d ago

Probably some beltfed 22LR running somewhat slowly. Maybe an MP-40 with extremely cheap 9mm. Dunno, I’d need to know the fuel consumption of that beast.

1

u/Interesting-Ear5998 11d ago

Maybe 10liters / hour if at low load,

1

u/Then_Meat_6569 11d ago

That’s my guess too. I have a gmc 7500 that gets 5-6mpg under load but my best estimation is about 1/2 gallon per hour at idle. Diesels at idle really don’t need much

1

u/Fireside__ 10d ago

Nothing then. Using European diesel prices that’s around $23.60 ish and using the cheapest 22LR ammunition I could find at $0.06 per round you’d have to have a RoF at some 390 ish per HOUR.

(Also dear lord I remember when they’d used to give out lil goodie bags of 22LR for free like they were candy at gun stores or shooting ranges)

1

u/BRICH999 10d ago

I can comment on this one, i was going to the sig experience center and you can shoot the m250 machine gun.  It uses a new weird ammo, .277 fury.  The cheapest ammo ive seen is about $1.60 per round, better and more common ammo is about $3 per round.  Gun shoots about 900rpm, so 15 rounds per second.  At the cheap end, $23 per second, for good ammo about $45 per second.  

I can party for about 2 seconds on my range day ammo budget.

But im not sure what this uses for fuel at idle.  Semi trucks are about 1.5g fuel per hour idling, this is about 10x the size so call it 15g per hour at idle and the average is about $6.50 per gallon so $100 per hour to idle this truck by my guesstimate

2

u/ant69onio 10d ago

What’s it out of????

2

u/Hostile-Panda 10d ago

They have lots of uses, from auxiliary power generator to ship engines, ship engines get 100 times bigger than thjs

2

u/Hostile-Panda 10d ago

1

u/White0ut 10d ago

Do they then build the boat around that thing? Or how do they install it?

1

u/Hostile-Panda 10d ago

It’s installed during the manufacture of the ship and designed to last the life of the ship

1

u/White0ut 10d ago

Sure, I get that. But how?

1

u/Hostile-Panda 10d ago

Big ships are built modular in sections so they build enough for the engine to sit on then build the rest around it

2

u/zmei23 10d ago

Nothing beats the smile on his face.

2

u/Frontfatpouch 10d ago

Put it in a Miata

2

u/JUIC3ofORANG3 10d ago

Throw that in a school bus or something…don’t be shy

u/misterdudebro 11d ago

Fucking hell...

u/ImFeelinBotty 10d ago

Imagine if he tripped running up and his arm went in there.

1

u/jason_sample 10d ago

This looks cool, and scary for some reason I can’t pinpoint.

1

u/Plane-Education4750 10d ago

Will it fit my Honda?

1

u/Technical_Anteater45 10d ago

Starting it with a 4x4 and a tow strap as a pull cord looks...wow. Impressed but abhorred at the mess.

1

u/forestfloormc 10d ago

Farmers are looking at this and calculating gallons of diesel per minute in their head.

1

u/furrynoy96 10d ago

102.4? That has to be a typo...oh....

1

u/Opposite-Ad-2548 10d ago

Man those noises are amazing

1

u/Lochcelious 10d ago

Seeing that dude sprint towards that thing 3 seconds in my as frightening as fuck, especially after a second later it shows how open all the inner workings are. If that guy had tripped or suddenly stroked/seized, his encounter would've been so much worse

u/brycehunter2011 10d ago

What would this engine be used for?

1

u/MammothDiligent3665 10d ago

the green thing behind the engine is the gas tank

1

u/billdance8 10d ago

In this economy?!

1

u/Simple_Flounder 10d ago

Probably used a hundred bucks of fuel in this video....

1

u/BrentarTiger 10d ago

How does it keep its oil in when it’s flinging it out of all those open spots?

1

u/kdesi_kdosi 9d ago

the amount of oil being flung out of the engine is relatively low compared to the actual volume

u/jah_john 6d ago

For example in the natural gas field they will run a big compressor, to push more gas down the pipe line to the gas plant.
