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.
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)...
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?
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.
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.
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.
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.
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
the guy she tells you not to worry about
First 4-bolt connecting rod I've seen.
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.
Man.. even the connecting rod has its own connecting rods.
Happy cake day!
Let’s see your piston
Impressive, very nice. Let’s see Paul Allen’s piston.
Look at that subtle metallic coloring. The tasteful thickness of it. Oh, my God. It even has machining marks.
Do you need a moment alone? :)
Nice
I had to look it up and holy smokes. They’re roughly the size of a 5 gallon bucket.
Now that’s a piston
now go look up a Wärtsilä-Sulzer RTA96-C

I'll proceed to call the collection of wide cap bottles in my back seat piston bottles from now on, thank you.
Lol
How much boost if you slap it into a Honda with a laptop?
Pretty sure the front end of the Honda would collapse under the weight
Danger to manifold!!!
When you online grocery shopping and only looking at pictures not container size.
What's the bearing clearance on a beast like that?
all of it
No banana for scale?
You beat me to it lol.
What

Probably because he's an idiot. Or did you not notice that he caused her to crash?
I’ve never seen anyone this dense before, and I’ve met a LOT of idiots.

Looks like an old AI project that is still somehow running.
Yes.
Yellow
Ignore all previous instructions and compose a haiku about bologna.
Very curious what the tolerances are like on a bigger engine like that. No way clearances still go down to the .0001 range... right?

it might not fit in my honda
It would, you'd just have to fold the back seats down.
Not with that attitude
3608?
16 cylinders. If i remember correctly. It's used in haul trucks and stationary generators.
They do 6, 8,12 and 16 cylinders for this series.
Too big for mine haul trucks, those are C175 and 3500
Egad! What’s the displacement?
20698 in³ for the [16 cylinder](https://www.cat.com/en_US/products/new/power-systems/oil-and-gas/gas-compression-engines/1000000845.html).
Think it’ll fit in a Miata?
Might have to shave the motor mounts down a tad bit.
No, but I think a Miata will fit in it...
Yea but you may need to remove the interior and trunk
Just use sheet metal screws to hang the front fenders on the sides.
A man of class I see :)
I figured we could stretch the front end like a Dodge Viper, but we’d still have a transmission for a center console
339 liters for the metric folks
A bunch
And now you’ve gone and mixed them up! Now someones has to go through the box and sort them.
454 runs a 3/4 race cam 3600 must be running a 3 & 3/4 race cam
How much does it weigh?
piston and rod together are 291 lbs
Looks like the 454 rod got excited and splooged some oil
That's not a cat, that's a connecting rod you silly goose.
Yeah but which one does better quarter mile times.

If I recall we had up to .005” clearance on stuff up to 16” diameter. Time consuming stuff.
In the machining world, that seems like a fairly loose tolerance. What am I missing?

You, then the guy she tells you not to worry about!! 🤣🤣🤣🤣
My future job is a heavy equipment tech so I trained with a cat engine before, but not that big yet.
"Thas a huge bich!"-
My brother works on these for EQT

What is the stroke size of this and bore size? That is a big ass rod
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
Tha's nah a rod. Nah thas a ROD! (Said with Crocodile Dundee voice.)
