The mechanic is Wolker Franck. I was a collaborator in the change of a Mak generator crankshaft in 1989 on the San Juan ship between Buenos Aires and Santos. A hydraulic coupling broke in the middle of the trip and I made it on the onboard lathe. Great person, he rewarded me in spades. I always remember your great work, Wolker from Hamburg. Abrazo Amigo..!!!

I love these type instructional videos,,very informative and educational. People dont realize how big this stuff is . Thanks for sharing this.

Ah yes, the floor here is made out of floor.

The piston studs are extended and coupled to hydraulic pistons that are arranged to pull together on the application of pressure. The force is reacted via the tube fitted over each stud, to the top of the head. This allows very precise and equal tensioning of the studs on assembly, the nuts simply being run down by hand to make firm contact, then the tensioning pressure is released. To remove, a little extra tension is applied to release the nuts that then may be freely rotated as we can see.

I'm just an old motor head, I've never seen anything like this before. This is very interesting. I'd never heard about stretching head bolts to loosen the nuts before. I'd be very curious to learn more about why its done that way. I can spend hours watching this stuff. Thanks for posting it

Its what you do when you tighten a nut, you are simply stretching the bolt, doing it hydraulically all the bolts are equally stretched the same length, hence evenly torqued.

Thanks. Something that just occurred to me while I watched it again, using the hydraulics so the nuts can be turned by hand, saves the threads on the studs. Also applying equal pressure to all the studs at once prevents the head from deflecting.

I love this vid because I am a chief engineer in the french navy, and I 'd like being a mechanic teacher. It 's good for improving my english as well. Thanks a lot to Caterpillarinc.

@tpvalley the charge air inlet is connected in a horizontal plane at the rear of the head. fastening of the charge air inlet is done via an o-ring, not exactly 'push-fit' but a flat face seal created when the head is tensioned.

The polishing ring that was removed prevents excessive carbon build up around the top of the piston crown above the top compression ring, this prevents carbon from polishing away the cross hatching.

I'm no marine diesel mechanic, but damn, that looked *way* easier than I bet it is. I see that system fighting you at every step.

it actually is this simple (with the exceptions of some bolts that's stuck). The annoying part is that these engines are usually inline 6-9, so you have to repeat this process a number of times corresponding to the amount of cylinders you have. Very time-consuming :)

I guess the bolts and nuts have some torque in real life [unlike effortless wrenching shown here]. Disconnecting a fuel line will spill its contents [not a dry tube as seen here]. Insides are more oily too.

Wenn man bedenkt, dass dies ein offizielles Marketing-Video von Caterpillar Inc. ist, und für sowas dementsprechende Anforderungen an die Professionalität gestellt werden, dann ist es schon fast ein Armutszeugnis, dass für den Kommentar kein Muttersprachler engagiert wurde. Dabei gibt es mehr als genügend Sprecher da draußen, die das können. Musste aber der hier sozusagen "fachfremde" Maschinenbau-Ing. nebenher auch noch machen, weil er doch so gut erklären kann (brrrr)

I wish some of this technology was available in engines a 10th this size. Exhaust manifolds that don't break off? anti-polishing rings? crankcase doors? This is a slow and measured process shown here and it IS only one cylinder, but I have spent quite a lot of time doing similar on smaller engines and had a LOT more frustration! lol

i want to repower to these 32 series so bad. were still running MaK 8-453c. they've done well for the last 20 years, but with retrofitting and increased kw demand the extra 700kw per engine would really be noticed!

That chain is FAAAAAAABULOUUUUUUUUUS.

for sure.... i worked for MaK for yrs, to fit 9 heads, all pipes, all rockers, tappets set and ready to run took 4.5hrs... (well it was a friday, and the pub was about to open)

Actually the pink color on the chain is a safety feature. The paint on the chain is a special compound that if the chain is used at excessive temperatures, the paint will turn brown. Excessive temperatures would cause the chain to lose it's strength and a safety hazard would result.

Thank you very impressive video and engine, I study small engine repair

Ii watch this video whenever I have insomnia... BOOM!... out in in 2 minutes.

@maw9779 Actually, that's incorrect. The lifting gear is all different colours depending on the testing schedule. For example, Jan - Mar blue, Mar - Apr Red, etc. This system ensures that only lifting equipment which has passed testing is used.

yeah... everything goes great when its not caked in heavy fuel, oil, and carbon.....

Easy to work on.

6:10 what is that "polishing ring" that he removes from the block? looks like the cilynder... is it divided in 2 parts? never saw that before.

After this video i was veering pink shirt, white canvas trousers, and holding a glass of chardonnay in my hand.

That is one beutiful engine.

Is that why they use them on some of the largest and newest ships?

What is the typical time cycle that this procedure is done?

Great work, I think bigger the engine, better to work on. Cat in one of the best diesel engines in the world. The biggest one I worked on is the 3406 for trucks and construction equipment. Wll look at website for more videos like this, Thanks for sharing.

+dizzywow It's a dry sump. The oil is pumped to a seperate tank by the scavenge pump and the engine driven lub oil pump sucks from there to the engine.

I wonder how easy that is to do on an engine that is 10 years old.... Still very interesting!

very good

is this already when caterpillar bought MaK?

The way the head nuts are removed is interesting. I guess that ensures no one will be doing thus job on their own.

Almost all large marine engines are done by a variant of this and have for a long time. The Studs are stretched hydraulically and then nuts put on to basicly and tight and hydraulics removed . Studs remains under stretch giving the holding force of the fastener.. Gives much more holding power than you could do by turning a nut to torque also even distribution of weight and more precise than any torque wrench would be too. I have seen a engine where a vender tried using torque instead. Worked for about a week then nuts loosened themselves and bearing was wiped!

Using a torque wrench to break loose bolts?!

New transmission CVT design by BitRaptor. Is a continuously variable transmission CVT gear only (the only one functional in the world), very compact and lightweight, and which could replace the current systems both for efficiency, simplicity and not least the costs. Because this CVT work only with pinions is better the all other systems by efficiency and high torque transmission. In the web page bitraptor com you will find more explanations, drawings and a short video of a basic prototype.
