- Old School Repair | Experience Machinist Rebuilding Wrecked Crankshaft From Main Journal
#brokencrankshaft #machineshop #machinist #cuttingedge #pakistanitruck #amazingtechnology #crankshaft - Jak na to + styl
40 years ago I worked at a marina and we had a pre WW2 Bucyrus Erie crane with an old 371 Detroit diesel in it. It only ran at an idle to run the winch. Crankshaft broke in half at a main bearing. It was so old and obsolete that no engine was available. So the owner was looking at $100,000 to buy a 50 ton crane. We had an old welder from Nigeria that said I will fix it for free if you pay me $500 for every month it keeps running for the next 2 years. Owner said sure go for it since it was stationary and we just lifted boats off of trailers and swung them out into the river just idling the engine. I was the youngest mechanic that was tasked with helping him fix it since he was just a welder and had no tools. So I pulled the engine oil pan off and cleaned off the worst of the oil. I was expecting him to have found a crank somewhere. Nope he simply took a die grinder with a carbide bit and rigged it up so it was inside a large shop vacuum hose so all the metal flakes were sucked up. I slowly turned both halves of the crank still in the block as he ground down the journal. Then he measured the bearing play and using paper he took up all the play in the remaining 3 main bearings. He then tack welded it and took out the paper spun the crankshaft and measured the run out on the end of the crankshaft. Satisfied with the results I bolted a steel bar on the front of the crankshaft. I would turn it slowly as he welded one complete pass. Then turn it slowly for a minute as he chipped off the slag. Then he would read the run out and decide where he would start his next pass. He was welding lying underneath the block and he was a better welder than any licensed pipeline welders that worked there. After about 30 passes he declares it is perfect and the run out was 0. So I am expecting that we now will take the crankshaft out and have it machined. Nope he declares we will just let it idle on 3 main bearings. It had oil galleries drilled in the block and he ran an external oil line to somehow bypass the welded oil gallery in the crankshaft. We never did anything else in the way of bearings or seals. We filled up the oil pan with diesel fuel instead of oil and he had put a bunch of magnets in the oil pan to catch any metal. Started it and let it run for a minute drain the diesel, clean off the magnets. Did this 3 times then filled it with oil and it ran for 25 years. It was simply beyond belief to anyone that worked there that he fixed it with no parts at all and had welded it while still in the crane. Truly amazing what you learn to do when there is no other option plus he made $12,000 for his knowledge. This guys repair was cool but I got to see the Nigerian method and it was way cooler to be a part of it. Sadly new owners bought the marina and scrapped all ugly old rusty equipment.
Nice story, thank's for sharing.
Друже! Яка країна?

Impressive and awesome, some learn how to adapt and overcome, while others throw in the towel.
Great story, thank you for sharing :)

но я думаю современные моторы серийных авто. не выдержат такое. так как там все алюминий ! новые авто бмв . мерседес проезжают 60000 -150000 км . и просто так починить ее без оригинальных запчастей большая проблема! ломается новых авто все! 5 лет в утиль. и покупай новую!
металл двигателя алюминий и тонкий
I live in the UK and went over to Pakistan to buy an old school Toyota BJ40. Had guys like him strip themp vehicle and rebuild it. These Pakistani craftsmen are very skilled and with the limited tools and lack of modern equipment, they do a magnificent job. Respect
Wow, straightening the crank within 3 divisions. The indicator is 0.01mm per division. so he straightened the crank to a total run out of 0.0012" BY HAND !!!
And the carbide tips appear to be hand brazed on to the tool ! A folded piece of abrasive paper set between a bar and the work !! Polishing the journal with abrasive glued to a wooden holder ! Polishing the rod journals as the lathe turns ! I am truly amazed, this has humbled me and I thought I was good, but not any more. I just learned a lot, mostly humility.
Yes it is amazing to see the work of a master...... and then we call these countries 2rd world countries when they can work circles around us and show us what is possible
Amazing skills as a machinist and welder. He machined both ends of the broken crankshaft, aligned it and did an interference fit with a hammer, welded a new journal, straightened the entire crankshaft, machined the new journal to size and polished it. Using ancient machinery like it was the latest. Bravo!
Don't think he used both halves of the original crank. He bored a hole 1 1/2" or so into the main on one side, then cut the journal down to leave a 1 1/2" pin sticking out on the other side, where did the extra material come from? I'm guessing they had another doner crank to use for one of the halves. Guy does have mad skills, though.
@@stevengabalis4986 yes you know he did this before so likely they keep whatever left of the cranks and use them to repair other cranks that broke somewhere else.

Gotta give the guy props. Lays the cleanest weld I think I’ve ever seen.
Right! And with a stick welder no less, the man knows his craft.
Looks like what we called 'Jetrod' - developed to build Liberty ships. Runs hot and only flat position. Strong but shrinks alot.
@@stanley917 Interesting, they all seem to use this type of welding technique over there. I've never tried welding myself, seeing this makes we want to take give it a try.
Yeah, really good welding
The welds are legit, not taking anything away from him at all but not everyone can turn their work while they weld. Pretty cool to just start his arc and then turn the crank to run his bead

Not often I come across a 30+ minute machining/welding video and watch it through and through, but this was absolutely worth watching. Awesome skills. I will never complain about a Miller or Lincoln slightly inconveniencing me anymore. Man did some amazing work with some quite old machinery. Also his way of straightening the crankshaft is insane.
I think it's a lot more art than science. No telling how many times he's done that.
People would be surprised how much of Japanese high tech is actually made on old machinery like in this video.

fortunate in US? lol us is fucked up hahahaha
🤑🤑🤑🤑🤑😇😇😇😇😂😂
Yeah, "fortunate", in the US welders have to buy their own protective gear, some are working in regular clothes, and you have morons like Elon Musk running companies, trying to do unionbusting, with all their wealth...

Extremely skilled and diligent. They appreciate what we Europeans and Americans no longer can, because we have become accustomed to the disposable and single-use world. I feel ashamed and have immense respect for them.
This guy is great considering what he has to work with. He's very meticulous with alignment, good welding (he has very basic welding equipment). A good craftsman.
Thanks
This is not a master.This is shit, not work.Such things are done in a factory, not in a hut where there is nothing
All respect
There is certainly nothing shabby about his welding skills. He's obviously had lots of practice with a basic stick welder.
Y la habilidad de tener el casco con las piernas y así poder usar las dos manos ,es de otro planeta el tipo ,y así y todo lograr una soldadura sin fallas
Lo que si falto es agregar primero al cigüeñal para luego usarlo como perno de guía y falta tratamiento térmico ,y todavía no se si aguantaría ,el uso

Вот это спецы. Всего хорошего им настоящие трудяги.
Это горе спецы, коленвалы не варяться, только просачиваются под ремонтный размер в соответствии с допусками. Сломанный вал это металлолом. Если бы так можно было их сваривать в России давно бы уже делали это. Коленчатый вал изготавливают из ковкого чугуна

@@user-zc3ty7ur2o Это сталь, сырец. Твердости нет совсем. Ее хоть молотком ровняй, с чугуна уже давно колен не видел. Даже на старых японцах сталь. Вопрос в другом, сколько такое колено проходит?

А вообще там новый надо было ставить, да и наждачкой полировать это такое, там же под вкладыши полировать надо. Ну если это у них ездит, то пусть будет так
Very very few people can truly understand what dude did here. I am very impressed given what he has available to him. 👏
Thanks
I agree he is a very talented scammer, no one could ever tell that that crank was scrap until they put it into an engine. I have seen major weld repair on engine blocks that they even make the weld look just like cast iron so a buyer would not know the block was scrap.
@@thepubliceye given the tools he has it's possible for that crankshaft to work, now with that being said I do agree with you and if it broke at that point there has to be a reason it broke and the weld is not as strong so it definitely is a high risk situation for the amount of work put into it.
@@wheelitzr2 There is no risk for this shop as that crank will be sold on the black market as just NOS or just used in good shape.
@@thepubliceye as much as I want not to agree with you I can absolutely see exactly what you said happening. And now why I will never buy a used crankshaft...

Absolute respect for craftsmen who can make such repairs the "old fashioned" way. In the UK people who could do such repairs were found easily in the Birmingham area until the 1960s. These days the "modern world" is all about consumerism, if it's broken just buy another one, so these skills are being lost adding to the waste and consumption, not a good thing where there are items that can be repaired with some ingenuity and hard work.
We have alot to learn from people like this, if only we could swallow our pride.
You know this video is fake, right?
Come to Birmingham now and we are all still here. You can get anything done here if you know who to speak to
@@MegaDargaryou've clearly never been to India Pakistan or Bangladesh
@@marekukawski202 its not fake, its how they repair things in india etc, and do a bloody good job as well.
@@vikingsmb Any1 with IQ higher than 50 knows this type of "repairs" are bullshit. The crankshaft are made from hard steel to withstand great forces, and this "welding" spot is shit tons of weakspot. If this will be ever mounted probably will breake loose again after very short time even unloaded. They do stuff like that in india coz? You watched a lot of youtube videos? Chech the % of death ratio in india :) Especially at work.
Мастер молодец, в таких условиях отличная работа, но напрасная и не вся. Диагональные масляные каналы в самом вале заварил(эти масляные каналы видны были когда вытачивал втулки для посадки одной половины вала в другую) под углом от шатунного колена в коренной масляный канал идут, который он в конце видео шарошил и точил от своей сварки. Отсюда вопрос: во вкладыш коренной как масло поступать будет? Весь коленвал внутри в масляных каналах, по которым идёт смазка коренных и шатунных вкладышей. Вал в месте, где варил, был немного длиннее (в начале видео когда доставали расстояние между коленами больше в центре, чем на других коренных шейках вала), он же две части вала одну в другую забил из-за стачивания коленвала на 2-3 сантиметра. Красивый, титанический, возможно точный, но напрасный труд.
😮
он же отдельной вставкой соединил половины. Тут безотносительно геометрии полно вопросов. Когда обтачивалась сварка, стружка шла "змейкой", это значит, что металл сырой и долго это ходить не будет. На заводе шейки закаливают при помощи ТВЧ. Будь шейка закаленная, стружка шла бы мелкой крошкой, да и не факт, что старые резцы ее взяли бы. Вопросы вызывает и прочность соединения: сварка делает структуру металла неоднородной, возникают внутренние напряжения. Такое варенное колено сломается снова довольно быстро.
@@AKWoland там толщина закаленного слоя минимальная, а сам вал и должен быть гибким, что соответствует стружке. Не знаю насколько там полезная или нет работа. Надо смотреть на допуски самого двигателя. Есть такие моторы которые с допуском в десятку будут работать и работать.
Маслянные каналы они потом сделают. Так в описании написано.
Геометрию он потом правит гидравликой. С чего ты взял что маслянные каналы заварены? Он как раз и выточил так чтобы отверстия на двух половинках совместить.
не обращайте внимание, !!!! тут в комментах собрались мастера 99 уровня , таким уродам даже 10 часть этой титанической работы не возможна , я еще не говорю о сборке целого вала !!!!!!!!! @@merlexrus

That was a pretty crazy repair, definitely beats the heck out of no crankshaft. I'd love to see it stuck in an engine and run.
I would also like to see how the engine runs afterwards.
@@cadtecsimplexcam4248 Its not like this is the first time they did this. It for sure runs, if it wouldn't they wouldn't do it/go down as a business. Look how many crankshafts that guy has in the background. We're just obsessed with overworked engines where everything is pushed to the max, same with the work cleanliness in a shop. At the end of a day, gasoline washing the dirt off and 2 oil changes after everything is assembled, makes the engine just as clean on the inside.
Who knows if it even went back in the engine maybe this video was just to show you a bunch of machining and that was it
Acil satılık araç 😄
@@em4703 It will run question is for how long, and in what kind of engine. If the engine is very understressed, like a big naturally aspirated Diesel that revs to 2k, it might work but any kind of modern engine with reasonable specific power this would not hold. You do not weld engine internals because the heat makes the steel weak. Modern engines have forged or case hardened crankshafts for a reason.
Поражаюсь любви и самоотдачи этих людей своему делу😥👍, сомневаюсь,что колено будет работать,но как знать, чудеса бывают 😀

I am a begginer Machinist, his job is Amazing
I ground and welded crankshafts for 43 years and am amazed at this craftmanship. We straightened cranks in the same pressure technique and used similar v-block stands, but always had some kind of hoist! I like his hand-held polishing rig too! It looks like he even makes a nice new radius on both sides of the journal. Years ago, I saw an article about the Kyber region of Pakistan where men were hand building firearms with what appeared to be vises, hack saws and files,(probably some kind of fire too), making functioning guns! All working people should witness this kind of videos to learn from and appreciate!

i welded stuff at my work that normaly would be replaced.. because i hate it.. got a raise for my skills while i think they are stupid xD
Not sure what you mean by up to date tools? That old lathe and welder are as good if not better then modern ones. CNC isn’t the answer to anything except volume production, and stick welding is the best method for this type of job.

@@blackdaan Sorry dont agree. With certain things breaking it and repairing it means additional risk that can end up with people dead or additional costs to company. the risk just isn't worth it. In this case as a professional company i would not do this type of repair.
@@Klote3241 yea that is treu. India does this to save money. And here replacing is cheaper. But we got addicted to that..
I work for a pump factory. We got a workshop for repairs. When a wedgetrack is damaged. Because the impeller broke of. Than they buy a new rotor. And i talked with the head machinest how it can be that milling a new slot is more expensive. He explained the rotor cost 40 bucks and they calculate me a hour to do so. Slot+check+balancing out. So its cheaper to throw them away.
But yea. I own a milling machine myself and a lathe welder etc. So what do i know. I just love this kind of mantality

Simply amazing. Enjoyed jeffadams story to.
Very skilled machinist. Any one else notice that's not the same crank? Its 2 different cranks made into 1 good one. Both ends he machined where a complete bearing journal that was torched off.
I was wondering how he got the extra material for the joint. Thanks for clearing that up. I suppose there's a good probability the old crankshaft was bent also.
Yes - I was wondering how he suddenly had extra material for pushing them together - great work.
One side has a crack the other a ruff cut 😐
I watched it 3 times trying to work out how he fitted extra section before I twigged - I'll check comments next time

حقیقتآ یک کار بسیار بسیار دقیق که حتمآ هم باید با دقت صدم میلیمتر انجام بشود و بسیار حساس است و درود بر شما .
I mean, I wouldn't really want a welded crank in my machine, but damn... man does good work. Especially with what he has.
The alternative in that region is probably that your truck will never run again and you won't make money.
With that in mind you would not have a choice but to install a welded crankshaft.
@@SwiffMeister that's kinda what I'm getting at, I get why they do it and this guy probably does about the best that can be done
i'd imagine they pop it in an oven and temper it. not perfect maybe but I doubt it will be the next thing to go on the car he's putting it in..
God old machines worked like that
New machines are not supossed to be able to repair from others then the original manufacurer (OEM)
@@truffleshuffl I don't think so, that would make the process more expensive. It is probably cheaper to replace it again if the engine breaks down after the next 700.000km.
Broken crankshaft? No problem! At We Are Being Crankshafts, you can be up and running within hours! And without that nasty expense for a new crankshaft! Eye protection? We are spitting upon your eye protection! I especially liked the cig during part of the fix. Seriously, I could really identify with this process, because I machined and ground a six-cylinder crankshaft on a cheap lathe (although it was a much smaller crankshaft) Kudos to the chef! Beautiful welding!

просто ремонт!
Это просто демонстрация процесса сварки того что первое попалось в руки. О каком ремонте идёт речь? 😂
@@user-wn7mu3cm3k так поэтому и сломалось, что вот так сделали изначально.
Какова будет надёжность ? - Не знаю . Тем не менее - ВПЕЧАТЛЯЕТ ! Мастеру респект !
Claro pois confiamos em uma máquina que fabrica uma peça nova do que na mão de um bom torneiro mecânico
Отличная будет надежность👍
согласен! но, гляда на задний фон, где десятки коленвалов, т.е. опыт огого-го... и учитывая уровень жизни... даже если на сезон хватит- все равно будет дешевле, чем новую машину купить.
От кармы клиента зависит
Это мастер с большой буквы! Уважение мастеру!
А у нас в России все выбрасывают потому что никто не хочет браться за такой ремонт. Не выгодно им таким заниматься.

This crankshaft is from an old diesel engine.
YOU CAN NOT, do this on a modern cars crankshaft it will snap again in under 1 min.
The vehicle in India/Pakistan/etc. are from a diffrent area in time. Machines where build to last back then not like the trow away culture we have today sadly :(
But people dont want to wait 2 - 3 weeks till that guy has time to fix there crankshaft. The want a new Shaft asap!
@Felix Spilles that's where you're wrong i have a mechanic who does all the time in Africa....most of our cars are pretty modern...but in western countries they don't....i am American i can tell you our mechanic will tell you to buy a new engine because they don't want to fix it
The pink "measuring twine" is classic. I made crankshafts for stock cars decades ago. Brings back old memories.
How strong is such a weld do you think?
It's called makeing do with what you have. Hats off to the machinist.
This guy can make welds with an old stick welder better than some tig welders I have seen. The skills shown here very impressive a true artisan.
Fffffcc
Sss
Tig & arc welding are completely different types of welding for very different applications, also his welder didn’t look very old.
@@WhiskeyGulf71 I mean the finished weld is so even and neat it looks better than some tig welds, I am well aware of the difference in arc and the other types of weld. Also that amp stud welder he's using is at least 30 years old, the curved shape sort of gives it away. Any I've seen since the 90's have square enclosures.
@@mercedesvan-doors34
It’s what arc welds look like if the correct amps are used with the correct grade of fresh rods, moisture is the biggest problem with arc welding rods.
His welder is made in his region, it’s a basic design that has fixed outputs but i would say, judging by how clean the terminals & housing were that it is very new.
Actual use of dial-indicator, believes in precision work. Makes a big difference. I was getting a bit freaked out, with his hand in the crankshaft while it was rotating though.
Yeah, great way to break a few fingers
@@LongTran-em6hc I would be surprised if he hasn't broken some toes over the years too. Lifting stuff like that with that footwear.
I'm surprised his sleeve hasn't caught on a burr and had his whole body dragged between the crank and the toolpost and shredded and ripped apart into a pile of crushed bone, meat giblets and bloody rags.
The run out is terrible. That crank is a ticking time bomb.
@@LongTran-em6hcgreat way to turn your body in an human coil . Not just fingers
Вот это да. Практически без инструментов, на древнем станке - это мастерство высший класс!
Good job Sir🎉
Treba ljudima pokazati sta je rad i znanje pod vrlo malim uslovima ja sam zivot proveo u kamionu i dobro razumijem koliko je to odgovoran i precizan rad.Bravo sve pohvale.

Excellent Job 👍 Work Hard And You Will win the World ❤
Absolutely Well done my friend goes to show you don’t need fancy computers to do a job like this old school tools and machines get it done just as good more hands on measuring cutting measuring bravo to you sir
Insanely good! I've never seen anything like this before.

электроды из гвоздей с кизяковой обмазкой
Лера, там таблички видны и они не из Китая
сварочный ток он через шпиндельные подшипники токарного пустил ?
Nice work right there. It looks like he had a donor crank to use to make the repair though. The original broken crank was broke right at the face of the counterweight and the ones he used for the repair both had stubs to machine down to make the fit the correct length. You can also see the torch tracks in the end of the crank pieces where he cut them, that is why they are so hard when he starts the original facing cut..
thanks for explaining that.... I couldn't work out how the crank was not shorter after he had prepared the faces for the join.
I'd like to see if that crank holds up under use, or if it breaks where the weld is
yes, in all his videos, he always uses another crank to repair the broken one.
im no engine man but if you have multiple broken cranks like i assume this magic man does couldnt you frankenstien the cranks together?
@@AJ........
Pęknie w miejscu spawania.
Takie naprawy to więcej minusów niż plusów.
Pozdrawiam
Plot twist. This is the fifth time that crankshaft has been through this shop.
У мастера золотая рука респект таким мастером 👍👍👍
That was some damn impressive welding with what he has. Also the fact that he achieved this kind of work is damn impressive.
I agree...now I wanna see if it holds up when the truck is worked
That was impressive welding regardless of the equipment. But considering the tools available and conditions it was mind boggling. The poking slag into the oil holes will lamd the crank right back at his shop though lol
@@AJ........ it wont last at all…this kind of reparation are useless
@@AJ........ @EmA the engine is from a CAT bulldozer and there is another video where it fires up with this crankshaft so i guess it wasnt a useless repair after all.
