Main Engine Crankshaft Deflection Reading | Chief MAKOi

Here's another technical video. This time, we send the cadet inside the Main Engine's Crankcase to take deflection readings.

I was a marine engineer in the 1960's with the Nedlloyd lines from Holland.
On our main engine, a 12 cylinder Sulzer we had main bearing failure of three main bearings, between the last three cylinders.
Oh horror, after arriving in port, Papua new Guinea, and when opening the inspection covers, shining the inspection light and seeing all those flakes of babbit underneath the crankshaft.
We had spare main bearing shells, but they still had to be hand fitted to the crank journals, we sure learned how to scrape the bearing material, apply prussian blue, turn the shell under the crank, take it out again, check the bearing pattern and again and again until perfect, I believe it took us a week, 12 hours on, 12 hours off to get the engine operational again, and of course we also took crankshaft deflections like chief Makoi so well explained here. What a job, I will never forget!
Thank you chief

Hail to the chief! I am a veteran mechanic. Throughout my career, I have worked professionally on everything from cars, to locomotives. But I have never seen anything like this. Thank you chief Makoi. That was one seriously interesting video.

Take note that this is a medium size 2 stroke cross head engine. The big ones are 50% larger bore and 12 cylinders.
They are seriously big.
I remember climbing around inside these wonders, hammering on everything to check if anything's come loose...in 70C temperature that is...phew...
Thanks for the great vids Chief ! -its nice that all the "land-crabs" can see how their necessities are moved around the world. Keep up the good work !

Chief, as a retired Marine Engineer I just want to hand out an "atta boy" for your efforts. Excellent content, very well presented. Wish I had this type of instruction, freely available, when I began learning the trade 40+ years ago. Great experience for the Cadet. He's lucky to get such tutelage!

[Horstroad]

I'm an aircraft maintenance engineer and I love these insights into other spectrums of the engineering world. Thank you

[mohammadmian]

Dear chief Makio love to watch your upload all the time. I wish you and your you tube were around back in early 1970 when I was sailing and working in shipyard as a young man. You are a good teacher all these youngster are very luck to have you around. They could and should benefit not only from your knowledge. If they don't then they are just KNUCKLE HEADS tell them I say so. Your willingness to teach in the manner your teaching just excellent. May God bless you.

Loving these technical videos, the functioning of a large ship is something most of us never see and is really fascinating.

[michaelscott]

It truly is amazing seeing how big these ships engine's are. Its engineering bit on a whole new level to your average car engine. Just amazing. Another great vlog on a ship life and mane the most important part, maintenance.

[JuanAvila-blml]

I remember taking and doing the readings when as a young sailor, and validating the measurement as a senior member of the propulsion division. Great video!!

[douglasboyle]

As someone who has worked on car, truck, and larger diesel engines the idea of an engine large enough to crawl inside comfortably is insane. Thanks for sharing this unique perspective with us. Stay Safe.

[molotov]

That slow rotation of the crankshaft is mesmerizing and oddly satisfying!

[warrenjones]

Hi Chief, thanks for the look inside the engine. Someplace most people will never get a chance to see. Cheers

[brucelytle]

Jus sayin' Chief! You do a good job showing what it takes to make the world go round!
I used to sail Chief Electrician on APL C10's. I held a 3rd's Steam License at the time.
I always asked my Chief Engineer if I could 'play' Engineer when we were LA where we replaced 2 cylinders of the Sultzer 12 cylinder engine. They were also doing an alteration on the cam lifters. I did a video of one time, but part got erased with a video of a Dutch guy in Kobe, explaining the history of Santa Claus through the different cultures!
What can ya say?
I worked for 5 (8+ total) years in the US Navy, mainly 38a Shop stuff. Fixed em, built em, and sailed em for another 40 years.
Most people don't understand how massive and powerful these engines are, and the precision that is required for them to operate at the power levels they do for prolong periods.
That said..
I still prefer the hum of turbines over the thumping of a diesel!
Keep it up!

[klausnielsen]

i was working at MAN diesel frederikshavn denmark. i turn/milled cam shaft for the injection pumps for the 2 stroke engines, and camshafts for the 4 stroke engines valves and injection cam´s.
it was amazing to see a brand new engine being started up for the first time, and thinking about some of the parts i made will be somewhere on the oceans for several years .
very impressive machines, and imagine, even it is big, the tolerances and presicion is tight and precise as in a motorcycle engine. all workers there was very proud of our products.

[LethalMercury]

Yes, that engine is absolutely massive! Now, imagine the size of the machines that MADE those parts!

[daklakdigital]

FASCINATING! I LEARN SO MUCH FROM YOUR VIDEOS. ONE OF MY WORK ACTIVITIES IS WORKING WITH CNC MACHINES SO I'M AMAZED WE WORK IN SIMILAR SCALES OF MEASUREMENT.

[FloridaJack]

You are a good teacher/instructor/explainer ... your continuing education and entertainment is appreciated. Thank You, Chief.

[hgc]

As a diesel mechanic, ships and ship engines have always amazed me. Such an amazing machine, the size blows me away

[johnkelley]

Simply fascinating how big these engines are! Thanks for sharing this.

[thedhlguy]

Thanks Chief your videos are educational and just fascinating. You must have been one hell of a instructor at the academy.
