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.
Belive me, working in the crank space, you get covered in lube oil. It is no way that clean. Been there many times....!both Gotterverkan and Man engines... all good fun at the time....!
The guy who posted this great video has done a marvelous job, the simple layman watching the video is exhilarated pretty easy work!!

you start watching one of these, and you just can't stop until you see how it turns out. You just have to make sure the piston goes back into the cylinder. The suspense is overpowering.
@@ajingnineba5250 you should post your comment at the top level, click where it says - add a public comment (geesh, now I had to watch the whole thing again. After two years, I couldn't remember how it turned out.)
If only every maintenance procedure was documented and explained this well at the place I work - would make training and getting guys up to speed so much easier.
Why can't my life be like this. When I'm on a project like this it's more like,,,, Special tools? Make something in the shop. Parts? We have welders and some random worn out machine tools from 1912, fix the old parts. Help? We gave you a whole crew of crack smoking Oompa-Loompas who speak an obscure dialect of a language you never even heard of before. Then of course they always ask "What's taking so long?"
they are working smooth but infact u will face many problems during overhauling some time hydraulic jacks problems, nuts and other components stuck ect and will take extra time.
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.

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?

Can not found any information for inspection (measurement and clearance) Piston skirt. please advice while and reason for replacing bronze ring on piston skirt
top ring gap, usually I put it opposite the thrust side, the bigger the engine the easier it is, bloody car engines these days, just crap, no room, covered in stuff that brakes, why do they wear gloves in Europe,
Not a single word about any "lock out, tag out procedure", that's bad. Don't you value your lives at sea or what? No one should enter the crank case before the engine is positively secured from starting.
I see paint stick marks on the piston skirt bolts and It makes me think it's for indexing the bolts so the locking wire hole location in the correct spot. Either that or for torque turn method of final torque spec.
Reminds me of a giant valve in a cylinder head more than a piston and con rod. No wrist pin eh? I need to look up exactly how this is set up... I wonder what an assy like this would cost! I couldn't afford the bolts !
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.

In my 15-years career I never saw the smallest piston then this on the video.....usually this size I saw only on Diesel Generators heheheeheheehehhehehe
I asked the Mrs how to mount the piston rod stuffing box and she directed me to Procedure 902-2 (or Video No. 32). I didn't ask her about the stern gland.

This is the shortcut way if you do what manual says you need to install the tilting tools which you delay about 1 hour. The technique how you handle the engine room crane perfectly. 😊😊

13:12 the locking wire in the upper left is in the wrong position, it'll help the nuts to loosen.
Which one
good catch
Good eye.
Well, it was like that when they took it apart, so it was like that for years. New wires were fitted in a good position.
Good, I'm not the only one who caught that.
And folks wonder y I take 30 minute poops?
you start watching one of these, and you just can't stop until you see how it turns out. You just have to make sure the piston goes back into the cylinder. The suspense is overpowering.
Good evening I am and electrician ,a winding man how can I learn more about generator A.C and altinetos
I wish to now more about generator repairs and maintenance in all types of situation l need your your help please

Well I'm glad I watched that now...it's given me something to do over the weekend, overhauling my MAN marine diesel engine...
If only every maintenance procedure was documented and explained this well at the place I work - would make training and getting guys up to speed so much easier.
These are the people who with their precision brought most of our comforts to our modern homes.
Good thing they put that bell ringing in there so I know when a new procedure is starting.

Another add my experience piston overhaul.
Sir why the skirt has branz ring like thing , for what purposes it is there
Glad to see them use a proper wrench to reinstall the piston lifting fixture instead of the adjustable one.
Preassure test first before putting the wire. Just saying
Bolts, not screws, there is a big big difference.... Atleast here in murika there is LOL
If there isn't a nut, it's a screw.
@@Mishn0 People say I'm nuts, how then can I have a screw loose ? I'm confused...
Must not believe in battery operated hand tools huh?
Thanks team ,
wonderfully explained.
This video just took the basic excitement out of the idea.
I fell asleep in the first 2 min.
at 13:20 the locking wires at left side are applied wrong way.
Yes. Well spotted. That one on the left is lockwired backwards. Bloody apprentice!
@9:42 secondary sub contractor actions being demonstrated
its funny everything is done so effortlessly, when in an actual working engine you struggle with each step
I was thinking to myself ‘look how clean their coveralls are.’ That’s my indication as to the level of reality to true working conditions. I’m no marine technician but i know a training aid from a workhorse when I see one.

Are they not permitted to use air or electric tools?
I've never seen an engine that clean, that needed maintenance

I will not be able to hear 'molybdenum disulfide' without cracking up!
AvE on youtube?
@@chiefaves Yes he is!
The pliers tool he had when resetting the locking wires....what is it called. I need one of those.
Check "Bahco Drahtwirbelzange" on Google. "Wire locking pliers"
I could watch guys working all day. Doin' A Fine Job!
are these engines 2-stroke?
Yes, crosshead engines are 2-stroke.
Don't wear a hard hat, land piston and rod on some flimsy planks and leave it balancing there, drench yourself in lube oil. Right.
You guys are really doing great job. keep going and spread your valuable knowledge....
top ring gap, usually I put it opposite the thrust side, the bigger the engine the easier it is, bloody car engines these days, just crap, no room, covered in stuff that brakes, why do they wear gloves in Europe,
Not a single word about any "lock out, tag out procedure", that's bad. Don't you value your lives at sea or what? No one should enter the crank case before the engine is positively secured from starting.
Are we just to assume that they are installing new rings? If so what is the purpose of measuring the old ones.
I see paint stick marks on the piston skirt bolts and It makes me think it's for indexing the bolts so the locking wire hole location in the correct spot. Either that or for torque turn method of final torque spec.
Incredible dimensions and yet "simple" to repair. Access everything. I would like to see such an engine someday.
This work in sulser, niigata, pilestic, wartsila, fuji, are not complicated like this
Is it necessary to remove telescopic pipe connection during piston removal for K-MC engines?
The main bolt safety wire was wired up backwards!!!!🤦♂️🤦♂️🤣🤣
Reminds me of a giant valve in a cylinder head more than a piston and con rod. No wrist pin eh? I need to look up exactly how this is set up... I wonder what an assy like this would cost! I couldn't afford the bolts !
Why we are measuring the free ring gap of all piston ring before removing???
I know the reason I'm glad I moved to Germany 55 years ago.
My new continue watch the video, how the piston overhaul. Addional my personal experience.
Why not land the piston head on a perpendicularly positoned wood plank so that it doesn't have the hazard of rolling over?
11:45
-nevermind, it was answered thereafter. 😂

Today is Saturday, today is add my experience. To how the piston overhaul?
I would like to know the price of only one piston ring ? Swiss watches precision, the size is the unic difference. Wonderfull.
Do I hear the mechanics speaking Afrikaans there? Or is it something similar, Flemish maybe?
great to see the training video. where do i take the test and start working?
For exchange the stuffing box, possibly for exchange without lifting the piston (exchange inside crank case chamber)..???
Great work, very entertaining but I wish the narrater would stop referring to the bolts as screws
I asked the Mrs how to mount the piston rod stuffing box and she directed me to Procedure 902-2 (or Video No. 32).
I didn't ask her about the stern gland.
That's not how to say molybdenum. It's mo LIB den um. lol
Very big engine
Fantastiske fremskritt på utstyr siden jeg startet med min første MAN for 50 år siden..........
No power tools???? Why??
Very didactic for machine students like me Thanks MAN
Why no power tools?
Mashallah
keep up the good sir
Aren't they called piston palm bolts. Who calls them screws?
How many women here?
Sure a lot of overhead crane work without a safety helmet in sight.
wanderful very professional job tank you
I’m baffled that they didn’t use any power tools.
they used mild steel wire wheels ??? and then they dont want the tolerances to exceed the values stated in the data sheet
Can't see my wife letting me do this in the kitchen and putting the bits in the dish washer

You see him working a grinder? He pretty much knows there's not much can be falling when he takes engines like this apart.
Safety zealots are out in force on this video.
why is he working alone and somewhat in the dark?
*bronz
Perfect job
Very good job, but where is the safety helmet?
The manual says not to tilt the piston horizontal without the stuffing box. Does it make a difference ?
This is the shortcut way if you do what manual says you need to install the tilting tools which you delay about 1 hour. The technique how you handle the engine room crane perfectly. 😊😊
Very useful
