It's always a treat to see professionals operating in their element. There may be many videos about rebuilding diesel engines on TH-cam, but this is the only channel I'd trust to get it technically correct. Thanks Chief!
@@rosegreensummer I'm sure the brain will gett the point after a few sweaty overnighters laying in the filth under a broken engine trying to fix it... 😜
Having torn down and rebuilt many a long block, it is so interesting to see this process done at a larger scale. Never had to use a block and tackle to remove a piston before. But all the parts are the same and recognizable. Also, never imagined that ships actually did this kind of over haul while underway. Thanks for posting chief.
For so many reasons besides the obvious one, where would we be without men, who design, build, and operate all components of our complex modern world. May God bless them.
a pleasure to see your videos, I am a student of Naval engineering and we are studying just the part of dismantling engines and defining their parts. Your video was very helpful for my study process and to see my future job as a marine machinery engineer. greetings from Chile.
@@tommysaulter9171 Even the largest locomotive engine is a miniature next to a slow speed two stroke engine. Watch Chief's video on measuring crankshaft deflection to get an idea of just how big the slow speed two stroke engines are. And that's not even close to the largest of them.
@@matthewbeasley7765... I have seen that video. Locomotive pistons on the engine that I worked on were 13.787”... And this was considered a “small locomotive” used for moving tank and hopper “Coke” cars inside a petroleum refinery... Edit: I have also done some small repairs on 3 old WWll T-2 tankers owned by Gulf Oil Corp., so I do know how big some of these ships motor components can be...
The engine driving the emergency generator is one step smaller then the aux. eng. shown in the video. If the vessel has a free fall lifeboat the next smallest engine will be the one propelling the FFB. The smallest engine will in that case be the outboard engine of the rescue boat😅 Why am I writing this? Just for fun!
This whole operation looks so smooth. After working a job where a sensor calibration turns in to a multi day affair with half a dozen surprise breakdowns afterwards I'm jealous.
Reminds me of my previous job tearing down and remanning Isuzu and Perkins diesel engines. Although they were pretty big they are nothing near as large and complex as those generators. Very cool to watch the process on a larger engine! Good work to you and your team!
That's a bit bigger than the engine I have on the generator in my garage. Always interesting to watch engine rebuilds. There are so many different types for so many uses. Planes, trains, ships, vehicles, lawn care, etc. Thanks for sharing this with us.
Good day chef. Good job there. I believe that this genset is HIMSEN (I have no experience on this engine). As I worked as supt, the crushial parts of dg overhaul are: 1. Conrod measurements as makers manual 2. detailed and very thorough crank pin measurements for diameter and ovality verification. Be very very careful there and it is suggested to take these measures by yourself 3. Liners measurements, giving major attention on the inner/upper part. Notes: I saw during dismantling that some of your nozzles were leaking. I am pretty sure that you will change everything Suggestions: 1. Check, measure and clean turbocharger. Also try to improve insulation as is damaged locally. 2. Do not reference only to makers manual. Check makers technical circulars. Sometimes the major information for a precise overhauling is there. I am pretty sure that your supt forward to you all these circulars. 3. Once overhauling is completed proceed with DG loading program ( gradual loading of kWs) as makers instructions Thanks for your great job there. I am waiting for more videos like this.
Thanks for another great video, Chief. Being a mechanic myself, it's still interesting to see how different engines are put together. They all basically do the same job, spin something, be it a wheel or a pump or a generator or a propeller, it produces motion. Safe Journeys and waiting for the next video. 🔧🪛🚢
This is one of my favorite videos of yours. You take something that looks very complex on the surface and steadily break it down, step-by-step, into manageable subassembly phases (before going into granular detail). This makes it easier to mentally process, and less intimidating.
I just absolutely ❤ this channel. I have learned so much. I love to take things apart, so this is a real teaching tool for me for the next time that I have to dismantle something and put it back together. This is just awesome. A dirty job, and a job well done. Thank you so much!
I've never been a seaman. But for me, watching your vlog is a good adventure for those who want to work in this field and would like to experience a real event on a ship. Awesome stuff, Chief MaKoi
It is always good to watch professionals working in sync with each other. I was chief engineer on a VLCC for sixteen years and I have never gotten tired of watch professionals working. Thank you for sharing this, Laurajane Mildon-Clews
Another great video Chief..having worked in about 34 different engine rooms (1976-2018) I been through a lot of overhaul jobs. Some bad weather may be heading your way around 3-5 next month if you're still in port.
I'm in awe. As a passenger, one just expects a ship to go from A to B. Without your videos, Chief, we wouldn't know what goes on 'behind the scenes'. Thank you to you, and all your colleagues worldwide, that keep the wheels of industry turning.
I like how, on a large enough machine, there's a manual way to access anything. For example the holes on the flywheel that allow you to turn the engine precisely.
your channel is one platform that will definately get me back on track and also prepare me to to get ready to get back onboard because i have been out of sea for a long time.thanks for the education.
Not only is this channel informative, but I can listen to you talk all day. Your explanation is as a college professor would talk to his students. It would be excellent to serve with you. But, at 63 a bit late.
I was on the team that rebuild the Diesel engines on my 637 class submarine and after that on shore duty I was on the teams that rebuilt the Diesel engines on the Trident submarines out of Bremerton Washington. Yeap it’s a lot of work with a lot of parts that need be taken off, cleaned, then reassembled. Fun stuff actually. Nice video Chief.
Thank you so much fur your detailed explanation of how you do your work. I am blind and feel your audio description is as good as bring acne to see it. Thank you Chief Makoi
Chief, I am one small voice but I could have taken a lot more detail on this one, but that is perhaps just my opinion. If you have more footage, have you considered perhaps a second channel? One channel for “ship board life” another for the “mechanical matters”. Please, take your time putting the engine back together, it is fascinating to me and thank you for taking the time to include us all in your life.
Always watching your videos Sir. Very informative and inspiring ❤️ Everytime I am losing hope to get my line up too, I prefer to watch your videos just ti be inspired that I will be on board soon.
Impressive your crew is so proficient on engine overhauls. In the oil and gas industry, our in-house mechanics often had marginal results rebuilding large Cat, Fairbanks Morse and GM-EMDs So we typically contracted the manufacturer or skilled rebuild contractor
I work in oil and gas industry as a CE on self propelled Jackup barge. I also worked on ships. I can definitely say that medium speed diesel like ships generator engine have simpler construction and designed to be overhauled onboard by ships crew. But high speed diesel like CAT are complicated construction and designed to be overhauled by a specialist.
@@nikhilbhale79 II was in O&G too, and that's how it seemed watching the Chief's video. The newer non-sleeved 1200 and 1800 RPM Cats were always problematic. The old CAT D398s and D399s were pretty dependable if a bit complicated, but straightforward and fast to overhaul (2 to 3 days), but they were fuel and oil hogs. I was intimidated at first by my old Fairbanks Morse 12 cly OPs but soon came to love them. Nearly trouble free, very dependable and a lot of reserve power. Overhauls were a reasonable undertaking if you had the right set-up. I liked the GM-EMDs for smooth and simple operation but an on-site overhaul took a specialized crew and a lot of time, about 5 to 7 days as I recall.
I will say that Japanese engines like Yanmar and Niigata are simplest to work on and really user-friendly. Their maintenance manuals are huge and gives every detail about maintenance procedures. Cat, Cummins are not user-friendly engines to work on. There maintenance manuals are also not so detailed.
@@engineerbythesea4100 I had a pair of YANMAR 6LP 300HP engines on a motor yacht (I think that was the largest they offered) and they were excellent engines! but not near the size class of the 800hp to 4,000 hp generators in heavy industry and global maritime operations.
Great video of a complicated process. I was involved in a valve job on a Detroit Diesel V-8 generator on a seismic survey ship underway while working off the coast of El Salvador, 1975. A couple of truck mechanics and me, a young Ordinary Seaman. Much simpler than your rebuild!
I didn't realize there were separate engines for the electrical generators. I somehow thought the generators were connected to the main engines. Interesting video, Chief!
When you sign up for a contract on a vessel do you know what scheduled maintenance items like this will be part of your responsibilities during your time on the vessel? Does the type and complexity of maintenance you will be responsible for play a role in negotiating contract terms? It is interesting to me that a ship owner would have important maintenance tasks performed by personnel that does not have a long term connection with the vessel or the owner. This whole industry is fascinating to me. Thank you for the peak into the unknown world of ocean transportation.
We have a Planned Maintenance System where we keep track of upcoming jobs. Familiarity with the operation, maintenance and repair of machinery is a requirement when applying for a job as a marine engineer. The more diverse experience you have (with different models, designs) the more in-demand you will be.
@@ChiefMAKOi so your experience helps you get the contract for the position, but you don't get to add a line item to the compensation for being responsible for such tasks. It is just another expected component of the job description. That adds another level of complexity to the unusual system of staffing vessels. It must be a very competitive workforce to allow such a system to work on an international level.
I was under the impression that you guys just sit around doing nothing until something breaks and then you just put a bandaid on it so you can get into port and have someone else fix it properly. This is amazing! What a crew!
Chief, You and your engineering staff are true professionals! I can’t tell you enough how impressed I am with your work! As always, thank you for the great videos!
@@3ne2nr4life Take it easy. Since I bought my car and put 37,000 miles on it it had oil changes and nothing else. Any engine work would be done at a car service facility. I think it is reasonable to assume that repairs/maintenance is not done on a daily basis at this level. Yet, credit to the crew that they are competent to handle (to me) involved maintenance like this while underway.
@@cestmoi1262 I've worked on ships for 12 yrs as a marine officer (not in the armed forces) and have seen at least 6 engineering teams dismantle, repair, recondition and assemble almost every part in the engine room on several ships. They work hard, precise and on some tight deadlines...
Good day Chief, have been watching your videos for sometime now. You are doing a great job. Salamat! Wish you and your crew fair winds and following seas!
It is amazing that you are granted such time to do a proper job. In my industry one man is barely afforded 2 days to in frame a CAT diesel engine, and that includes rolling in new bearings and repainting
Wow ! What a job ! Rather you than me 🙂 ! I've done a bit of work on some small motorcycle engines before now, but they were very simple engines, and I didn't deal with any bearings. This looks like a marathon task. Thank you for showing this Chief 🙂 .
These diesels don't look like anything I've ever worked on, but I've worked on your typical Cat,Cummins and Detroits. Another interesting video, Chief.
What does it say about me? I know how to work on diesels, and I know how they operate. I wasn't trying to be a smart ass. All I was stating was that it was an interesting video.
Chief MAKOi, with great humility, the "Cylinder covers" are best called cylinder heads as well as the "Attachments" are best called ancillary hardware or components in English. Always great video's!!
I'd love to have a blue water vessel of my own. The older I get, the more I understand that old man fantasy of saving up money, buying a nice boat, and just sailing around to random parts of the world. Growing up, my family had a boat, but it was small, and we only took it out on Lake Travis for the day. I know the wide open seas are a challenge, but I like a challenge. Anyway, I'll keep dreaming from my condo in Chicago. Lake Michigan is so big, it kind of looks like the ocean. 🤣🤣🤣 Oh, quick edit: I love working on things with my hands. I work in jewelry, and I love repairing watches. The way I focus on what I'm doing while I'm working on a watch is rather zen-like. In its own way, it's peaceful. Until something goes wrong, anyway.
Thank you for another great informative video. This is an Engine Design educational video they need to show in engineering schools. I get to see the process several times when I worked in the repair shipyard in the past. A more interesting process will be the main engine overhaul. :)
3:17 cut with knife around cable is a big no, may unknowingly slice into the cable insulation and cause hidden trouble down the track. I learn it the hard way and saw other people cause problem.
Even a partial overhaul must be a challenge in a foreign port, rather than in home port. Chief, you got me missing sea life. I probably would have liked the Navy, if it had not been for the military! LOL I have always enjoyed mechanics, and how all those parts work, what each one's function is. Your engine is a little different than the ALCO engines we had aboard ship. 6 main engines and 3 generators. But they all shared the same size pistons, heads etc... That air driven pump you were using to extract the oil from the crankcase, we called a 'sandpiper.' Maybe you do as well. But the air powered pump wouldn't make sparks, when pumping more flammable liquids, like JP5. And your crew always seems to be there... A good team, no matter which ship you're aboard. But in your videos, we never see what's going on behind the scenes! "Get to it you slouch! I'm trying to make a video here!!" LOL Peace to you Chief, and a big salute to you and your crew...
You would assume that the main engine would have some kind of pancake alternator arrangement on the flywheel and then have at least two UPSs to reduce the amount of auxiliary generator operation necessary to periods when the ship is moored. This would still get N+1 electrical reliability, with the UPS backed up with auto-start generators. Noting also that main propulsion is only N, which seems adequate! Do you carry out your own onboard lubrication oil analysis while at sea to assess bearing wear in the main and auxiliary engines, or mail samples out when in harbour ?
@@ChiefMAKOi Interesting, so I guess you look at acidity and can maybe check viscosity but need more metallurgical interpretation from the lab. I suspect also that your kW per litre of swept volume are less than Mr DieselpumpUK extracts from screaming Mercedes engines, but that your overhaul intervals are rather longer apart!
something I didn't know that those large ships have an engineering workshop obvious now you have explained it also never knew these scheduled maintenance things where done at sea on a programmed basis again thanks for the upload and hello from Australia. Just a question can this be done even in bad weather or don't those gigantic ships roll much ?
Noon pa man Idol kna si Sir. Kaya nag try din ako mag VLOG. Thank You Sir and all the best in your future endeavors. Continue to INSPIRE us all with your amazing work Chief MAKOi Sir!!!
Very interesting thanks Chief. I know it's only a small (for you) engine but I'm surprised no air or battery tools are used and chain blocks instead of electric. Slower but more forgiving perhaps? And the old pipe on the ratchet trick. I suppose we'll find out in pt 2 how you torque the big ends down
Reminds me of overhauling the Continental AVDS-1790-2 V12, air-cooled twin-turbo diesel engine on the M60A series tanks, except at larger scale. The M1A series tanks upgraded to a jet engine which I also overhauled. It's less greasy for sure, but so many little parts and an exacting 3 level phase rebuild based on engine hours. Lots of fun, except on cold lonely nights.
I'm an engine guy, have been for 60 years - Gas, diesel and jet engines. Professional training on all. This video is GREAT! I presume you have parts washers and bead blast equipment on board along with a small paint cabinet along with all the micrometers you might need? 🙂 Fuel injector testing equipment for spray patterns?
There is so many lesson when chief makoi make a vidoe... ive learnd a lot from all of his video. Next sir can we tacle about the Difference of Auxilliary engine and Auxilliary machinery engine ? Thanks
I love your channel chief... its always mind relaxing to watch your videos...it smooths our sail after watching your videos...plzzz keep up your good work...looking for more inforamtive videos like this...if possible please add some videos for boilers too
Watching this event in the engine room, I am remembering my own active years in the commercial navy in the 1980s&90s one of the hardest and difficult jobs ( engine room) we had in harbour was called cleaning the scavenges scraping off the residual of those processes it was a real job from hell very high temperatures =50* Celsius was normal also very restraint space to work and suited up with special overalls protecting from the chemicals we used to clean up that crusts that were on the side of these cylinders i have no idea if this is still done by the crew these days anyway Chief Makoi thank you very much for your always pleasant and informative videos they always bring me in a sweet nostalgic mood !!
That must be something from the US.😅 Boost pressure instead of charge air pressure. The first time I saw that below a pressure gauge, I thought: what the f.. is meant by that?!
Hello sir I have searched many TH-cam channel to get knowledge about this but I haven't found detail video like you I joined as a trainee Engineer at one of company which provides services like you I have not any knowledge about this job but when I watched your first video I firstly subscribe you with the help of your video I am learning a lot now I have a confidence that I can do this plz upload more video with overhauling engine with more details 🙏👍
I have done several times doing engine overhauling on our 6. Units MAN B&W 18V.28/32H. In our stationary Power Plant here in Saudi Arabia. I love my job as Engineer
Clever design, incorporating those lever holes in the flywheel so that the crank can be turned by hand during maintenance like that. It's the kind of thing that would be easy for a design engineer to overlook.
Can you filter and use the old waste oil for fuel? Your spare part inventory must be large. Also replacement gaskets, seals, clamps, along with screws, nuts and bolts need to be on hand. Very enjoyable video Thanks
You can probably neither confirm nor deny, but am I cynical to suspect that not all companies take maintenance as seriously. Probably also a testament to your leadership that your company does!
Had to strip one or our Paxmans down for catastrophic failure of a piston leg. Luckily, it did no more damage than it did. A LOT of shrapnel !. One of the pieces, made a small hole in the swimming pool. Oh what fun Took us about 3 months to get all the parts.
Thank you for such a complete video on generator engine overhaul. Are you at liberty to say the make of engine, RPM, horse power and generating capacity of the unit. Thanking you in advance.
so interesting how the piston heads come out. The hole that the hook threads into, with the carbon build up how does that work? Do you have to run a tap in to clean the threads or is it a little hook. How do those little holes not affect the way the piston fires?
It's always a treat to see professionals operating in their element. There may be many videos about rebuilding diesel engines on TH-cam, but this is the only channel I'd trust to get it technically correct. Thanks Chief!
100%
AGREE WITH YOU
Oh yes, boring maintenance beats stressfull emergency repairing everyday! 😉
Thank you for another great vlog, looking forward to part 2!
please tell that to my workshy student procrastinating brain with a loudhailer

So many critical connections and small parts, before the main work. Testing and start up must be very stressful. Thanks big guy, great content.

Are you serious🙄... Clearly, you've never been on a any type of seafearing vessel.
Chief, You and your engineering staff are true professionals!
I can’t tell you enough how impressed I am with your work!
As always, thank you for the great videos!
@@3ne2nr4life Take it easy. Since I bought my car and put 37,000 miles on it it had oil changes and nothing else. Any engine work would be done at a car service facility. I think it is reasonable to assume that repairs/maintenance is not done on a daily basis at this level. Yet, credit to the crew that they are competent to handle (to me) involved maintenance like this while underway.
@@cestmoi1262 I've worked on ships for 12 yrs as a marine officer (not in the armed forces) and have seen at least 6 engineering teams dismantle, repair, recondition and assemble almost every part in the engine room on several ships. They work hard, precise and on some tight deadlines...
@@3ne2nr4life
so who says you can't learn anything on the internet. I think I did alright with my new found knowledge. Thanks everyone.
Good day Chief, have been watching your videos for sometime now. You are doing a great job. Salamat!
Wish you and your crew fair winds and following seas!
Your videos are awaited as the Messiah Chief Makoi. Very good job. God bless you.
It is amazing that you are granted such time to do a proper job. In my industry one man is barely afforded 2 days to in frame a CAT diesel engine, and that includes rolling in new bearings and repainting
Awesome work!
Never realized how much work you do yourselves instead of relying on "specialists".
Thank you for sharing this video , it is very useful for engineer
Many thanks from former ship eléctrician, i was in Manila 1983...
What a fantastic video, Chief. Nice to see the high-level details.
Thank you Chief, we are looking forward to the next episode.
Wow ! What a job ! Rather you than me 🙂 ! I've done a bit of work on some small motorcycle engines before now, but they were very simple engines, and I didn't deal with any bearings. This looks like a marathon task. Thank you for showing this Chief 🙂 .
Brings back so many memories part 1.
These diesels don't look like anything I've ever worked on, but I've worked on your typical Cat,Cummins and Detroits. Another interesting video, Chief.
What does it say about me? I know how to work on diesels, and I know how they operate. I wasn't trying to be a smart ass. All I was stating was that it was an interesting video.
love this channel chief. glad you guys are ok!
Chief MAKOi, with great humility, the "Cylinder covers" are best called cylinder heads as well as the "Attachments" are best called ancillary hardware or components in English. Always great video's!!
Chief, I always enjoy your videos. Thank you so much giving me a peak into a world that that is fascinating.
This was really good. Looking forward to part 2. 🇺🇸🎃
I'd love to have a blue water vessel of my own. The older I get, the more I understand that old man fantasy of saving up money, buying a nice boat, and just sailing around to random parts of the world.
Growing up, my family had a boat, but it was small, and we only took it out on Lake Travis for the day. I know the wide open seas are a challenge, but I like a challenge.
Anyway, I'll keep dreaming from my condo in Chicago. Lake Michigan is so big, it kind of looks like the ocean. 🤣🤣🤣
Oh, quick edit: I love working on things with my hands. I work in jewelry, and I love repairing watches. The way I focus on what I'm doing while I'm working on a watch is rather zen-like. In its own way, it's peaceful. Until something goes wrong, anyway.
So much talent on show..much respect.
As usual, an excellent video. Thanks Chief
Hello from the great state of Michigan
Thank you for another great informative video. This is an Engine Design educational video they need to show in engineering schools. I get to see the process several times when I worked in the repair shipyard in the past. A more interesting process will be the main engine overhaul. :)
3:17 cut with knife around cable is a big no, may unknowingly slice into the cable insulation and cause hidden trouble down the track. I learn it the hard way and saw other people cause problem.
Even a partial overhaul must be a challenge in a foreign port, rather than in home port.
Chief, you got me missing sea life. I probably would have liked the Navy, if it had not been for the military! LOL
I have always enjoyed mechanics, and how all those parts work, what each one's function is.
Your engine is a little different than the ALCO engines we had aboard ship.
6 main engines and 3 generators. But they all shared the same size pistons, heads etc...
That air driven pump you were using to extract the oil from the crankcase, we called a 'sandpiper.' Maybe you do as well.
But the air powered pump wouldn't make sparks, when pumping more flammable liquids, like JP5.
And your crew always seems to be there... A good team, no matter which ship you're aboard. But in your videos, we never see what's going on behind the scenes! "Get to it you slouch! I'm trying to make a video here!!" LOL
Peace to you Chief, and a big salute to you and your crew...
This is a birthdate present. Looking forward to see the next part. Thank you.
Those are interesting connecting rods. Round shank and 4-bolt connection to the cap. I've never heard of a Hyundai Himsen diesel.
very professional engineers. I love the insight, wow so complex but they make it look easy. thanks chief
now i know how complicated, tiring the job is for overhauling a generator kudos to my hubby who does this
You would assume that the main engine would have some kind of pancake alternator arrangement on the flywheel and then have at least two UPSs to reduce the amount of auxiliary generator operation necessary to periods when the ship is moored. This would still get N+1 electrical reliability, with the UPS backed up with auto-start generators. Noting also that main propulsion is only N, which seems adequate! Do you carry out your own onboard lubrication oil analysis while at sea to assess bearing wear in the main and auxiliary engines, or mail samples out when in harbour ?
Both. We have kits for onboard analysis and we also send the samples to the lab.
@@ChiefMAKOi Interesting, so I guess you look at acidity and can maybe check viscosity but need more metallurgical interpretation from the lab. I suspect also that your kW per litre of swept volume are less than Mr DieselpumpUK extracts from screaming Mercedes engines, but that your overhaul intervals are rather longer apart!
something I didn't know that those large ships have an engineering workshop obvious now you have explained it also never knew these scheduled maintenance things where done at sea on a programmed basis again thanks for the upload and hello from Australia. Just a question can this be done even in bad weather or don't those gigantic ships roll much ?
Excellent voice over narration, super informative.
Noon pa man Idol kna si Sir. Kaya nag try din ako mag VLOG. Thank You Sir and all the best in your future endeavors. Continue to INSPIRE us all with your amazing work Chief MAKOi Sir!!!
Very interesting thanks Chief. I know it's only a small (for you) engine but I'm surprised no air or battery tools are used and chain blocks instead of electric. Slower but more forgiving perhaps? And the old pipe on the ratchet trick. I suppose we'll find out in pt 2 how you torque the big ends down
Reminds me of overhauling the Continental AVDS-1790-2 V12, air-cooled twin-turbo diesel engine on the M60A series tanks, except at larger scale.
The M1A series tanks upgraded to a jet engine which I also overhauled. It's less greasy for sure, but so many little parts and an exacting 3 level phase rebuild based on engine hours.
Lots of fun, except on cold lonely nights.
I'm an engine guy, have been for 60 years - Gas, diesel and jet engines. Professional training on all.
This video is GREAT!
I presume you have parts washers and bead blast equipment on board along with a small paint cabinet
along with all the micrometers you might need? 🙂 Fuel injector testing equipment for spray patterns?
See video description.
Looks like a well oiled crew. Great video.
There is so many lesson when chief makoi make a vidoe... ive learnd a lot from all of his video. Next sir can we tacle about the Difference of Auxilliary engine and Auxilliary machinery engine ?
Thanks
I love your channel chief... its always mind relaxing to watch your videos...it smooths our sail after watching your videos...plzzz keep up your good work...looking for more inforamtive videos like this...if possible please add some videos for boilers too
Watching this event in the engine room, I am remembering my own active years in the commercial navy in the 1980s&90s one of the hardest and difficult jobs ( engine room) we had in harbour was called cleaning the scavenges scraping off the residual of those processes it was a real job from hell very high temperatures =50* Celsius was normal also very restraint space to work and suited up with special overalls protecting from the chemicals we used to clean up that crusts that were on the side of these cylinders i have no idea if this is still done by the crew these days anyway Chief Makoi thank you very much for your always pleasant and informative videos they always bring me in a sweet nostalgic mood !!
It's always a beautiful moment, watching someone else do the dirty work. 😉
Fun, in class we are starting to reassemble our Detroit series 60.
Not called cylinder covers where I worked these are CYLINDER HEADS, Worked on GM EMD16, CAT 398,COOPER BESSAMER during apprenticeship
That must be something from the US.😅
Boost pressure instead of charge air pressure. The first time I saw that below a pressure gauge, I thought: what the f.. is meant by that?!
Hello sir I have searched many TH-cam channel to get knowledge about this but I haven't found detail video like you I joined as a trainee Engineer at one of company which provides services like you I have not any knowledge about this job but when I watched your first video I firstly subscribe you with the help of your video I am learning a lot now I have a confidence that I can do this plz upload more video with overhauling engine with more details 🙏👍
Thanks and welcome
Fewer people in the world has these talents. Nobody wants to work hard anymore.
I have done several times doing engine overhauling on our 6. Units MAN B&W 18V.28/32H. In our stationary Power Plant here in Saudi Arabia. I love my job as Engineer
Clever design, incorporating those lever holes in the flywheel so that the crank can be turned by hand during maintenance like that. It's the kind of thing that would be easy for a design engineer to overlook.
Can you filter and use the old waste oil for fuel? Your spare part inventory must be large. Also replacement gaskets, seals, clamps, along with screws, nuts and bolts need to be on hand.
Very enjoyable video
Thanks
You can probably neither confirm nor deny, but am I cynical to suspect that not all companies take maintenance as seriously. Probably also a testament to your leadership that your company does!
Had to strip one or our Paxmans down for catastrophic failure of a piston leg. Luckily, it did no more damage than it did. A LOT of shrapnel !. One of the pieces, made a small hole in the swimming pool.
Oh what fun
Took us about 3 months to get all the parts.
Best regards HUSNI MOHAMMAD ARMIN, 3rd engineer from Indonesian chief.
Thank you for such a complete video on generator engine overhaul. Are you at liberty to say the make of engine, RPM, horse power and generating capacity of the unit. Thanking you in advance.
I'll include it in part 2.
İ been preparing for my first contract as engineer thanks chief
so interesting how the piston heads come out. The hole that the hook threads into, with the carbon build up how does that work? Do you have to run a tap in to clean the threads or is it a little hook. How do those little holes not affect the way the piston fires?
Sometimes we need to tap. The designers have already calculated the variables for combustion so it doesn't really have any negative effects.
@@ChiefMAKOi Very interesting Chief. Thank you.
Also very good camerawork to get clear angles for the time lapses.
