Try doing this at anchor off somewhere like Dubai or Singapore or Hong Kong with the outside temperature 40 degrees, and when the engine is still hot, with hot oil dripping down on you inside the crankcase. Looks fairly easy, but the reality is that it is pretty back breaking work. Brilliant video and would have made our jobs easier if we had this to view when I was at sea.

Ah yes I remember it well. Doxfords mostly, Harlands, B&W, 1966 to 1972. This is looks like it was filmed at the Engine Builders and not on a ship. Where's all the oil covered surfaces in the Crankcase. My overalls only looked like that when I took them out of the bag brand new. Think the Doxford was a 750mm Dia bore.

It becomes even more impressive when you realise that Diesel engines, especially large medium and low speed marine engines like this one, will run on pretty much anything. They can even run off of unrefined _crude oil._ So if you have a ship or a power plant that runs one or more of these engines, you can just use crude oil to power them, although they mostly use Heavy Fuel Oil (HFO, a.k.a "bunker fuel" or "bunker oil") or things like Low Sulphur Fuel Oil (LSFO), Marine Gas Oil, or Marine Diesel Oil. And to all you idiot greenies with your hair on fire: 1. These engines can run off of LNG, LPG, methane, ethane, propane, butane, methanol, and ethanol as well. 2. You don't even need to modify everything to run on just natural gas. Diesel engines are inherently dual-fuel capable. 3. And most importantly, Selective Catalytic Reduction and exhaust gas scrubbers exist for a reason. And they exist because the exhaust gases contain lots of NOx, and sulphur too if you're running high-sulphur fuel like sour crude oil. But the SCR system helps cut down on NOx emissions, decreasing the formation of smog, and the scrubber helps to remove sulphur, phosphorus, heavy metals (mercury and lead primarily), and other harmful substances. The scrubber's ability to remove almost all of the sulphur from the exhaust gases means that the amount of acid rain formed is so little you don't even have to worry about it. As a result, the container ship that you see out there, despite being powered by a two-stroke Diesel engine that burns extremely dirty fuel, can still have very low emissions. There, you happy now?

That's a little baby engine that looks new at the training facility. Should show grown up engine, hot and dirty with damaged or missing special tools over the years. Or companies who save money by not supplying OEM parts that don't quite line up. Or have 12 hours of maneuvering to have to start job @ fwe to be told have to make next tide to maneuver back out. He also doesn't have hot oil dripping on him or working in slippery as shit crankcase. When engineer s die and go to heaven, this video is what it looks like. Look at the clean boiler suit, damn I'm jealous. Most ships I've been on have spare piston and crown built and ready to go so it's more swap out and rebuild later. Engineer best friend is is spray any metal to metal surface or gasket with GN metal assembly spray otherwise lost time cleaning surface s or seized together.

Thank you for your question and very relevant observation. Safety is a very important aspect of engine maintenance and is always an essential focus area for MAN. As stated in the beginning of the video, the Instruction Manual always overrules in case of any discrepancies as the latest manual will always contain Safety- and Maintenance instructions according to our latest Service Experience. This video was shot over 10 years ago and today we specify, that the flat surface of the piston foot should be placed on a perpendicularly placed wooden plank to prevent any rolling movement. It could also be an option to combine both the perpendicular plank as well as the planks in the piston crown end displayed in the video; The combination of instructions and common sense will always ensure the best Safety.

Locking wire is obsolete. It takes a lot of practice to install it correctly, even then the lock wire can break from stress or actually be severed while rubbing against a case hardened bolt head. Most locking wire is made from soft steel commonly called mechanics wire. A hefty cotter pin would be much more durable and way less time consuming to install.
