How do you grind a Crankshaft this big?
I’am stunned!

By the time you pay for machine work on it, it's just as much $ to get a new stroker setup.

I noticed it is very low RPM, I wonder how important or tight the tolerances are on something like that.

Just think how long the shoe laces would need to be and how much emery cloth it would take to polish that baby! Ha.

Who knew?
From an online "Technology Review" .... "The crankshaft is semi-built comprising combined crank pin/web elements forged from a solid ingot and the journal pins then shrunk into the crank web." I suspect anyone within a mile of that forge could feel the impact. It's bizarre to think there's a need for something so huge, but I guess if there's a will, there's a way...

Yeah; from 15,000 to 14,999…

No big deal, but I would hate to be the guy who has to set the stroke on the grinder or dress the radius on the grinding stone!

Some more perspective on the size. Notice the turbocharger.
Used to propel ships like this. I work for the tugboat company you see in the video. The small tugs are 92' 4700 HP and the large one is 138' and 8000 HP. For a total of 23,650 HP to assist the ship to the dock. The CMA CGM Benjamin Franklin in the video was only capable of carrying 18000 20' containers. The latest ships now are capable of carrying over 24,000 containers. https://www.youtube.com/watch?v=ytkvvvpGRzs https://en.wikipedia.org/wiki/CMA_CGM_Benjamin_Franklin https://gcaptain.com/chinese-shipyar...at-24346-teus/ https://maritime-executive.com/artic...orld-s-largest

The bigger they are, the slower they turn. A typical EMD locomotive engine , 645 cu.in per cylinder, 12 to 20 cylinders has a top speed of 900 RPM..a so-called medium speed diesel.

George, I have overhauled EMD fuel injectors. They’re only four feet long and weigh around 100lbs each. Our opening pressure test rig had an actuator handle three feet long.

There is a "Crab" which spans two adjacent cylinders to hold them down to the fabricated block. Torque on the crab bolt is 1600 ft-lbs as i recall. Who has the torque wrench?
