Thank goodness there’s a CZcams tutorial for this! I almost had to pay a team of engineers and maintenance workers to complete my repair!
I really did laugh out loud.
I have a piston ring expander 34:11 if you need to borrow it.
I cant believe my luck. I have SEVERAL cruise ships in my backyard and ALL of them need crankshaft replacements. I didnt know how to fix them, but thanks to THIS video, I can now get all my cruise ships back out earning money. WOW thanks 😢
Everything I needed to know. Have to put a new crank in my ocean liner next weekend.
Do you need a helping hand ?
Best make some cookies and drink coffee
Good thing this video came out. No way could I have changed my ships crankshaft without this! lol
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!
Impressive work on that crankshaft. Some tight maneuvering to get that thing in place. I can only imagine the curses that would be shouted if they dinged that precision machining when swinging it through the tight passages.
Most impressive technology and craftsmanship, all too often taken for granted. Thank you. 2023/09/24. Ontario, Canada.
many thanks for allowing us to see something we would never ever have been able to see. BUT thanks to your superb work we GOT to see it..once in a life time view for many of us! PEACE !
If man can do such brilliant works why we can't live in peace
there's no money in peace.
If woman can make babies, why can't frogs talk?

You had ONE job Bob! Put the lock washer on the prop nut! LOL!
It's eye opening to see how dependent we are on the skills of others.
Holy word salad descriptions of repair and maintenance procedures, Batman!
I found the best part the restoration of the Elbe. To realize it was built in a time that Dutch shipbuilding was still significant. Which started to decline in the early to mid seventies.
Tears are one of the most corrosive things on a ship. Underpaid workers cry a lot and their salty tears corrode everything. It is good to see someone talking about it.
I like the deep voiced Sims characters talking in the background
Thanks, team. Nice to see the range of skills needed to get a ship fixed up nice. And the folks who do the biz! Thanks MAN for your footage - doubt I'll need it, but thanks anyway. Very interesting. I'll keep you guys in mind for my next ship repair. Gotta keep those big boys floating, right?
Cool, now I can change my mate big Piston in his big Boat. This handy to know. Thanks my Mr. boat people and patch holes too
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.
I agree robo narrative should be demonetized. Whose to say they actually edited it
Robo-narrator and AI generated script.
Taking the you out of youtube...
Terrible script and pronunciation. Thumbs down. 😡🧐😡
Yes the robo voices kill the video !! The ads sound better than the documentary.
She looks so nice all polished up. I really like big and this one covers that eh.
Britain used to do this work.
Service industries and an endless supply of foreign labour will replace all that and, of course, the 'City' with its financial wizardry leading the world, will supply all the foreign exchange the government wants.
Unfortunately there are rumours that this is beginning to slip!
These robo-voice narrations are a plague on CZcams.
Totally agree…the AI is absolutely terrible.
They are an instant thumbs down for me…
CZcams Please remove these long on point add CONS
Wow, thanks every one for your surport. My Pleasure
I wasn't sure until he said wear a tear.
Brings back memories done this type of work several times on ships and large generators in power stations
Wow, what an extraordinary job repairing a very special tanker that I have ever seen. Thanks for sharing the video...👍
That was a wee crankshaft. I don't know how a big main engine crank is changed. They probably hope it'll never be necessary!
"The unsung hero's or our world"...
Hats off to the designers who thought how the access was possible through the various decks
This is the best DIY channel on you tube!!!!!!!! Is that a big block crank?
I assure you that that crankshaft was NOT sourced from Montevideo. It was custom made by the engine manufacturer, probably in Europe. Montevideo was the port of entry.
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.
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.
Her one can see MEN, knowledgeable MEN working
well done lads on the riveting
That piston seems like its engine was steam powered when it came out so CLEAN and several references made in the dialogue to "stuffing box" plus the fact the rings seemed to be rubber not hardened steel etc?
Amazing work.
Thats impressive, the process must have been designed into the ship design to allow the crank shaft to be got out. The actual access was so tight it must have been designed
gee wiz - - - do you suppose they use "designers" when planning and building a ship?
Ha yes I know it sounds dumb but its impressive the detail huh@@manifold1476
Not all the time a ship is designed for easy maintenance, my co workers and i did a Cat C18 in a pleasure craft and we carried the head and other stuff by hand and there was only room for two techs and everything had to be carried by hand inside the engine room
Very interesting and in depth descriptions. 👍
Wow I love to refurbish stuff but what you showed is way beyond.
Amazing ! Great job guys
Fortunately I'm now qualified to change the crankshaft on my next cruise should there be a malfunction at sea. One of these type tutorials would have made a huge difference in the movie U-571 had those guys had this same type of technical training before going on that sailing.
Thanks for this vidéo !! Good job ...
Amd we're all buddies😂
The slowed-down voices made it seem like a kid was in charge of audio.
Burpeg from Damon Australia. Do you know?
I remember working on this very shaft....... we were all soo pissed off at the end of the job, cos just after the video finished, my mate Dai shouted " fuck...... ive only gone and left my hard hat and vape on the fucking cam shaft" 😂 🏴
Fascinating video. When the crankshaft was changed I didn't see any reference to big end/main bearing replacement. They must do that surely?
See us guys in the blue jumpsuits? We are the guys that make the mega bucks! ...
For a moment, the incessant narration paused and I though "finally", but it started up again
Respect! ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤🥰
A lot of love !!! Very cool !
I can do it😮⁉THANKS🙄for your encouragement. I will do it‼😂🤣
One of my ships had a spare prop shaft that had to have the side cut out to get it out
This is a special job.
I wonder what the clearance is between bearings and crank shaft and did they get replaced.
Note to person reading the script.
It is ' WEAR AND TEAR ' pronounced 'ware and tare'.
it's a computer program
note how it pronounced the word bow incorrectly given the context of the video
"Person" lol
Like the detail in shed even got matterson locomotive jacks , have to get loco on the the jacks with bogies out
Increíble proceso y solo para una anillada gracias x el vídeo en lo automotriz somos más rapidos
Ooo man, that tire wire job. Ooof.
Nice video 👍
That ship the ELBE looked ready for the scrap yard.
You have never worked on a ship have you
She is still going strong. Volunteers keep her sailing every summer season.
I thought it was a new video, that replacement has been around on here for a while.
Not got a great memory huh
@@gowdsake7103Lol, the crankshaft replacement is old video for sure, this guy has just rehashed it. My memory is impeccable!
This looks like a remake to me. Thus robot voice. Am I right?
good video
That's right conserving materials rebuild not new
Impressive to say the least
Good video i Like !.
T.y.
Ships and boats DO NOT have a "Tail Sharft". They have propeller shafts.
At 1:04 Additionally... additionally what?
Sounds like an AI narrator because of mispronunciation of certain words
What's worse? The bot talking over the non-original footage or all the bots in the comments saying all the great things about the video.
i uses to repair these insitu 50 years ago
Where is the wrist pin on that piston? how does the connecting rod move with the crank journal?
What a ball buster.🙄
👍👍👍
the stupid work of welding done in the end and then all welding spark and dirt going in in engine housing . may be the ship owner new will buy another crank shaft soon or early hahahaaa
After all that work, they lower it down onto weld splatter.
WHAT ?
15:56 There's a lot of it too. Must be that millimetre tolerance he mentioned, that's just the biggest spatterball size clamped between all those machined surfaces..
Have you heard about something called "editing"? it's where you adjust the images to match the sounds or narration.
Ah yes of course! Good old 'Procedure 903-1'. I'm just reading it now. Don't forget to check data sheet 102-1.
Well,the german way of,....bla,bla,bla
Salam sukses ❤❤❤
How many master riggers to they have on the payrole?
I wish CZcams had a filter for text to voice vids.
Keren !
- is that about replacement of lithium ion battery
I knew they used safety wire on aircrafts, but I I didn't know they used it on ships.
Where was this video on career day?
I when I worked many years ago looked after smaller but still Ro Ro ships in the Langton Dry Dock in Liverpool but never saw what everything entailed as regards to it`repair one thing it was not allowed to put to sea again until it was authorized by the Maritime Authority
This is old video or what ? Why the mecanics doesn't used modern batery power's tools.
Faq green peace!
How much does that MOT cost
Pro tip: stay away from those "white box" ship crankshafts. Use only genuine replacement ship crankshafts.
LOL! What are you saying exactly... no "Hecho In China" cranks? I'm sure AliBaba or Amazon can have one boxed up and shipped to you in a few days? :) sarc.
How are they able to haul that huge ship out of the water?
They don't. They pump away the water around the ship.
What's with the zombie voices? 😂
Can I buy all the tools needed at Home Depot?
Ran it out of oil did ya?
What about the spots where the blocks are that the ship is brought in and stood on.
The docking plan takes that into account. They will either refloat it and move it several meters, or place the blocks in different spots for the following drydock period
oh yeah, they paint them too, duh
What is up with the screwed up voices you can constantly hear in the videos?
The word meticulous is being overused in your videos and it's driving me mad😂
The crankshaft is the last thing I'd expect to wear out on a marine engine. Unless it's very old or something like poor lubrication could result in premature wear on the shaft.
Anything that constantly runs in salt water is going to wear out no matter how well it's maintained. Salt water is pure evil on any equipment! Not a matter of IF it fails.. it's WHEN.
What are those gremlin noises in the background?
6 minutes in, no mention of a crankshaft.
You should ask the police how they keep their light bars on the top of their vehicles.
The screws look a lot like bolts
Pretty sure that crank swap, is from another video on yt.
