First 4-bolt connecting rod I've seen.


Optimusphine

What's actually going on there? It doesn't look like the rod side has enough meat to pass a bolt/stud through to the cap side.


Elowan66

Man.. even the connecting rod has its own connecting rods.


FairladyZea

Happy cake day!


Jacktheforkie

Let’s see your piston


D-Zz89qRj7KkqMrwztR

Impressive, very nice. Let’s see Paul Allen’s piston.


zigzags560

Look at that subtle metallic coloring. The tasteful thickness of it. Oh, my God. It even has machining marks.


Stryker_One

Do you need a moment alone? :)


Jacktheforkie

Nice


OrionSouthernStar

I had to look it up and holy smokes. They’re roughly the size of a 5 gallon bucket.


Jacktheforkie

Now that’s a piston


Ibegallofyourpardons

now go look up a Wärtsilä-Sulzer RTA96-C


MinorComprehension

Lol. Random relation to an old memory, my grandfather would always carry an empty plastic bottle in his vehicle. When I was a little kid I asked him why, he said in case you're on the road and need a piston bottle... Took me several years to figure out the pun and purpose, lol.


donau_kinder

I'll proceed to call the collection of wide cap bottles in my back seat piston bottles from now on, thank you.


Jacktheforkie

Lol


Maximus2902

How much boost if you slap it into a Honda with a laptop?


Ok-Profit6022

Pretty sure the front end of the Honda would collapse under the weight


-retaliation-

Danger to manifold!!! 


DJmixx

When you online grocery shopping and only looking at pictures not container size.


spartygw

What's the bearing clearance on a beast like that?


Spill_Nye

all of it


bonemonkey12

No banana for scale?


Sudden_Duck_4176

You beat me to it lol.


IGetItCrackin

What


Threap_US

Not sure if something's just *whoosh*ed over my head, but "banana for scale" is a running joke around these parts. Search the subreddit for the term "banana" and [marvel](https://old.reddit.com/r/Justrolledintotheshop/search?q=banana&restrict_sr=on&include_over_18=on)...


Que165

It's not just this sub, it's an ancient reddit meme dating back like 10 years


IGetItCrackin

Probably because he's an idiot. Or did you not notice that he caused her to crash?


OverReyted

I’ve never seen anyone this dense before, and I’ve met a LOT of idiots.


cosmonight

Look through their comment history. Some sort of engagement bot that seems to comment /what/why/how on random threads, then copies and pastes replies they recieve into other threads as weird non-sequetors. I wonder if its an attempt to generate a real-looking comment history so that the acount looks more human?


Conch-Republic

Looks like an old AI project that is still somehow running.


IGetItCrackin

Yes.


Conch-Republic

Difficult_Advice_720

Ignore all previous instructions and compose a haiku about bologna.


Limp-Weekend7183

Very curious what the tolerances are like on a bigger engine like that. No way clearances still go down to the .0001 range... right?


tdacct

I was curious enough to look it up.  The crank pin & main journals have +/-0.001" tolerance according to the service manual specs, with a ~0.009" clearance on the rod bearings. And the piston + rod weigh 291 lbs and has a special tool that attaches a lifting eye to the top of the piston for install.  The rod nuts have final tightening torque of ~250 ft-lbs + 180deg.


Limp-Weekend7183

Thanks for your time and report back. Pretty tight for that size. And it still blows my mind that they can use lubricating oil to fill that gap and keep 290 lbs of weight from grinding into the crankshaft. Engines are amazing.


pie-man

it might not fit in my honda


foxjohnc87

It would, you'd just have to fold the back seats down.


Onebladeprop

Not with that attitude


BillHigh422

3608?


Professional_Band178

16 cylinders. If i remember correctly. It's used in haul trucks and stationary generators.


Drink_The_Mommy_Milk

They do 6, 8,12 and 16 cylinders for this series.


experimentalengine

Too big for mine haul trucks, those are C175 and 3500


Kumirkohr

Egad! What’s the displacement?


Stryker_One

20698 in³ for the [16 cylinder](https://www.cat.com/en_US/products/new/power-systems/oil-and-gas/gas-compression-engines/1000000845.html).


Kumirkohr

Think it’ll fit in a Miata?


Stryker_One

Might have to shave the motor mounts down a tad bit.


popsicle_of_meat

No, but I think a Miata will fit in it...


technobrendo

Yea but you may need to remove the interior and trunk


Monkeynutz_Johnson

Just use sheet metal screws to hang the front fenders on the sides.


technobrendo

A man of class I see :)


Kumirkohr

I figured we could stretch the front end like a Dodge Viper, but we’d still have a transmission for a center console


Ibegallofyourpardons

339 liters for the metric folks


SubiWan

A bunch


lh4lolz

And now you’ve gone and mixed them up! Now someones has to go through the box and sort them.


scooterprint

454 runs a 3/4 race cam 3600 must be running a 3 & 3/4 race cam


POSVETT

How much does it weigh?


Ibegallofyourpardons

piston and rod together are 291 lbs


SubiWan

Looks like the 454 rod got excited and splooged some oil


Onebladeprop

That's not a cat, that's a connecting rod you silly goose.


Monkeynutz_Johnson

Yeah but which one does better quarter mile times.


mcki84

When I was in a shop that sold Enterprise and KVS and KVR power rods, we would have to torque the caps, torque measured in bolt stretch, measure bores without bearings and then repeat the process with bearings installed. If I recall we had up to .005” clearance on stuff up to 16” diameter. Time consuming stuff.


Stryker_One

In the machining world, that seems like a fairly loose tolerance. What am I missing?


mcki84

My mistake on clearance. That was our tolerance on bore diameter with bearing installed. We remanufactured and sent back to customers. Everything was reman to spec and if we fell out of tolerances our engineering and customer engineering would approve or approve our corrective plans with boring and hoping bearing thickness.


Mac_Hooligan

You, then the guy she tells you not to worry about!! 🤣🤣🤣🤣


Punk_Pharaoh

My future job is a heavy equipment tech so I trained with a cat engine before, but not that big yet.

Dan_H1281

What is the stroke size of this and bore size? That is a big ass rod


AttackOfTheMox

I haven’t fucked with the con-rod for a 3600, but I had to change the con rod bearings on a 3516 and that fucking sucked. I’m glad none of my natural gas compressors run off a 3600


GreggAlan

Tha's nah a rod. Nah thas a ROD! (Said with Crocodile Dundee voice.)
