I'll stop griping about my TINY 2-stroke snowmobile crank.. LOL. I'm teaching myself how to rebuild them. I'm not worthy after watching them stuff this 7 TON crank through a wing window.. LOL. Amazing work. I had an opportunity to work in a ship yard in my younger days - I wish I had done it. I think newer ship designs are more modular so they can be taken apart much easier for jobs like this (not that cranks are replaced often). Modular designs can swap sections in/out and re-configure the ship quickly. There are videos on submarines doing this already. I would also think that with today's tech and the fact these huge engines run at low RPM - they'd make the cranks 2-piece or maybe more. Great vid! Thank you!

May years aggo, I heat treated these large crankshafts prior to machining. We softened them by heating them, then we, hot straightened them,..These 4 to 6 meter crankshafts are now ready for machining. After machining they will undergo additional heat treating to harden them so that they will give satisfactory service.

Great video. It's obviously not a DIY video, but it gives a tremendous insight into the engineering and maintenance of these big ICE engines. I didn't notice which fuel is burned in these motors, but I assumed the basic crude instead of diesel.

@bigredc222 8 ай бұрын

After you refine crude oil and get gasoline, kerosene and whatever else they can get from the crude oil, the junk that is left over is called bunker oil, that's what these engines burn. It's thick like honey, it has to be heated just so it will flow through pipes. I believe they start the engine on number 2 oil / diesel, then once it's up to temperature they switch over to the bunker oil.
