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.

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.

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.

@@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.

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.
@@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.
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..
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.
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.

Great video Discovering Skills! 🔥 Those welds look like they were done by a machine 😮 I wish I get to be a skilled as this guy with practice 💯 Thank you for the video! 🤜🏾🤛🏾
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.
@@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.
@@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.

*this called root welding..its done all the time in structural welding. They know what a MIG welder is... but a stick welder is better suited for this. The lathe used is a $50k machine* ...
@@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.
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
Really great seeing this obviously very skilled and experienced craftsman/technician performing his work. The two crankshaft pieces he is working on don’t seem to be the ones removed from the engine at the beginning of the video. The crankshaft breakage was at an angle. During processing, the craftsman is turning down one one the crankshaft pieces at the breakage area and hollowing out its center (female). He then turns down the other crankshaft piece at its breakage area and leaves a stub at its center (male), to be inserted into the first crankshaft piece. Now the two joined crankshaft pieces together are shorter in length than the original crankshaft by the length of the aforementioned stub. Or has the craftsman made both crankshaft pieces “female” and joined them by a common pin? If so, that important step was not shown in the video. Or did I miss something? Thanks for making the effort of filming, editing and posting these very satisfying videos!
Looking at how many cranks were in the shop they may well have been the ends from two different shafts with a common inherent fault of breaking in the same place
The joining process is way more interesting - they just hammer (!) one half into other - without any measures for rotation angles, oil channels adjustments etc... It looks like totally garbage work just for video
Excelente peoficional, trabalho muuuito bom, a solda mesmo é uma das melhores que eu já vi (escamadinha) mas me tirem uma dúvida os especialistas como é feito o teste e o preparo para dureza do material que foi recuperado?
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!
I used to get annoyed when my auto darkening screen was set to the wrong level. Doing this kind of work without gloves, holding your mask between your knees and working out in the wind? Impressive.
29:15 safety measures be damned. Long sleeves? No problem. Wonder how many mistakes this guy has made that knocked his fingers around. Can’t be too many or else he wouldn’t be doing it
@@PorkusMaximii Of course Karen speaks up.. I was referring to the ability to ignore distractions, not the wisdom of working without safety equipment. But then, my welding helmet alone probably cost more than this guy makes in a month doing this in the middle east. If we accept that this was a successful repair performed under those conditions using those tools, I stand by my observation. Impressive.
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.
@@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.
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
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.
@@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...
Amazing! Customer desperare: “oh mu God my crankshaft broke into 2”, with the hands on the hear. The artist “oh no problem, I Fixed houndred like this, just give me a few days and it will be looks like a new one”. Just no words! Outstanding!
@@erickmoenga1206 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.

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
@@ДмитрийФ-в8л 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? Если не турбодизель, а это скорее от какого-то грузовика колено, то побегает, если с турбиной, ну, дай бог чтобы не перегружали. 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
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........ @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.
This professional left me speechless. With that little garage and that tool, it's amazing what He's accomplished. My admiration and respect for this professional, everything done perfectly. Greetings from Germany 🇩🇪
Will it be in balance?!? It looks like it won't from the video maybe it's good enough for whatever application they're using it for 🤷♂️ i may be wrong but compared to how precisely they balance them out of the factory this looks very crude. E.g. after the welding he balances it on his lathe (which doesn't have self-centering jaws so ... how do you know it's perfectly centered to start with?), ok. But then he proceeds to machine it and drill it - won't _that_ affect the balance? 🤔 or he hammers the two halves together and never checks if the hammering e.g. skewed the hammered segments to the side? Or he just welds the two halves together by hand. How is he sure there's exactly the same weight of material all around the weld? It may be round (bcs he machines it) but is the mass distributed perfectly evenly? 🤷♂️ Again - maybe i'm wrong, maybe it doesn't matter, maybe it's good enough. But i wouldn't trust it.
He uses a four jaw chuck, which is common actually. Especially on huge parts. He uses the indicator and a hammer to true it to the lathe and dead rest. He realigns the two halves again on the lathe but with the metal hook looking thing and a hammer. Probably unbalanced as hell though and unevenly tempered.
Fantastic craftsmanship this. Enjoyed watching this. I was on the edge of my seat watching this though, watching his sleeves nearly getting caught on the lathe 😮
Guys calm down he probably knows very well what he is doing and what the risks are...better than you but thats just a wild guess. His sleeve was never ecen close to being "nearly caught", trust me.
It is a great and wonderfull skill .. but im confused, if the shaft break in 2, then you joint it as male and female, it has to be shorter than original length .. unless there is a step, to lengthen the shaft to deal with overlapping male female joint, which is not shown in this video ..
i am very curious how well these repairs hold up. my whole 47 years of life experience is saying this is sketchy as hell, using a pocket rule to measure journals......but at the same time, If it works????
fully tested the truck now holds 45 swammies hanging off the side, 30 goats, 500 bags of rice and 2 camels while driving up a mountain road sideways. ;]
Brother, this is high-tech, comparing to others who film this sh*t. He uses gauge, makes sure everything runs true in the lathe. Seems like he welded it coaxially, checked it afterwards. Plus these older engines dont require such tolerances as newer ones. So yeah, tools are crude but he knows what he is doing.
This some skill to be admired, good work sir. You would never know that crank was broken in two. Awesome. Respect to people like this. In most country's this would have been scrapped, but not in this machine shop.
One upon a time things were repaired and not bought new and replaced. Sure the precision of the repair may not be as good as German engineering with CNC and laser measuring equipment, but it puts the dozer of truck back into service. What would you do if you owned a vintage car or motorcycle that broke the crank or spun a journal bearing and the crank is no longer available new or 2nd hand? Get it welded and machined down to size.
Always wondered how they get both pieces timed together, and get the welded journal straight and if it will last ? Those machinists are trained well. When parts are expensive and labor is cheap, you fix it !! Great Job. Thanks
@@backyardbasher See how many crankshafts he has in the background? I can guarantee you, he wouldn't have so many customers if they popped so easily, in a Low RPM diesel truck motor this should be fine.
That's the key. "Realism" has gone to ridiculous levels and all ancient wisdom is being tossed aside as superstition. Basicly science religion has made it so that while most of the people think something is impossible, it is so and only very strong minded persons can dispell the mass dispell that is all around us. There is in principle no limits what mind can do if you have true belief in accomplishing something. Before Musk you could ask any top rocket scientists and they would tell you it's not possible to make a reusable rocket that can land itself whit its main motors. We could truly do wonders if people would not put each other down all the time, starting from kindergarten.
When cranks are ground (not machined) it is vital that the rod journals are concentric to the centre line. The fact that the crank was polished would kind of indicate they don't have a grinder and the crank was straightened the journals will likely have a slight taper. In modern computerized engines this will throw an imbalance code. It also may not turn when the rods are installed. 1 degree is huge and taking 0.010" minimum would help the rear match the front.
That brings back old memories, I started out in a job shop doing similar work. The only difference is we had carbide inserts to use. I never really got too efficient at shaping and sharpening those old carbide and tool steel tools. I used mainly manual machines, lathes, mills, boring mills and an old Iron worker. We mainly made and repaired parts for the old Homesteak gold mine.
@@stephenbloom2545 I use to make those cranks, 2 lathes and an end mill. Most of them were cast iron very few of them were steel. Those look cast to me so I cant see that weld holding up for very long any ways.

Total respect for this man and his skills, what a good craftsman for sure.
This is a guy that you want for a teacher. Nicely done.
@@Rongamer104 Yes really, He has very good basic welding skills. Unlike most of our University Educated (Textbook Engineers) who can only talk about it.

@@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

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.

@@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.

I'm suing him for giving me arc-eyes.
我修了一辈子大车,第一次见到曲轴断了也能烧焊驳回再用,这才是真正的大师,佩服,
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?

@@LongTran-em6hc I would be surprised if he hasn't broken some toes over the years too. Lifting stuff like that with that footwear.

Great video Discovering Skills! 🔥 Those welds look like they were done by a machine 😮 I wish I get to be a skilled as this guy with practice 💯 Thank you for the video! 🤜🏾🤛🏾
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
End result.....junk
Definitely old school, these guys are called artisans for a reason. Massive respect from me.
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.
People like this guy are amazing.
There used to be lots of them in UK, but one by one they pass on and nobody replaces them.

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.
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
Very interesting! May you be blessed with safety and health.
Really great seeing this obviously very skilled and experienced craftsman/technician performing his work. The two crankshaft pieces he is working on don’t seem to be the ones removed from the engine at the beginning of the video. The crankshaft breakage was at an angle. During processing, the craftsman is turning down one one the crankshaft pieces at the breakage area and hollowing out its center (female). He then turns down the other crankshaft piece at its breakage area and leaves a stub at its center (male), to be inserted into the first crankshaft piece. Now the two joined crankshaft pieces together are shorter in length than the original crankshaft by the length of the aforementioned stub. Or has the craftsman made both crankshaft pieces “female” and joined them by a common pin? If so, that important step was not shown in the video. Or did I miss something? Thanks for making the effort of filming, editing and posting these very satisfying videos!
Looking at how many cranks were in the shop they may well have been the ends from two different shafts with a common inherent fault of breaking in the same place
Это куски от разных(но аналогичных) коленвалов, похоже. Один кусок отрезан от другого коленвала с запасом на обработку, я думаю.
I think they're two parts from different crankshafts
@17.06 the joint is welded.
The joining process is way more interesting - they just hammer (!) one half into other - without any measures for rotation angles, oil channels adjustments etc... It looks like totally garbage work just for video
Looks like he takes alot of pride in his work. That is missing from alot of tradesmen/craftsmen these days.
The second they start the engine it'll snap in half again.
Excelente peoficional, trabalho muuuito bom, a solda mesmo é uma das melhores que eu já vi (escamadinha) mas me tirem uma dúvida os especialistas como é feito o teste e o preparo para dureza do material que foi recuperado?
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!
When I started work 55 years ago almost every machine man had either a 'Woodbine'
a 'Roll Up' or a 'Pipe' in his mouth when the auto feed was engaged.

Gloves cost money, skin grows back.
@@PorkusMaximii Of course Karen speaks up.. I was referring to the ability to ignore distractions, not the wisdom of working without safety equipment. But then, my welding helmet alone probably cost more than this guy makes in a month doing this in the middle east. If we accept that this was a successful repair performed under those conditions using those tools, I stand by my observation. Impressive.

How did he accurately clock the 2 pieces, by eye or what? That needs special attention if you want all your timing and balancing to be right.
15:35 he was comparing with an adjacent rod journal and tapping the crank to get it to line up
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 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.

😂
Will it be in balance?!? It looks like it won't from the video maybe it's good enough for whatever application they're using it for 🤷♂️ i may be wrong but compared to how precisely they balance them out of the factory this looks very crude. E.g. after the welding he balances it on his lathe (which doesn't have self-centering jaws so ... how do you know it's perfectly centered to start with?), ok. But then he proceeds to machine it and drill it - won't _that_ affect the balance? 🤔 or he hammers the two halves together and never checks if the hammering e.g. skewed the hammered segments to the side? Or he just welds the two halves together by hand. How is he sure there's exactly the same weight of material all around the weld? It may be round (bcs he machines it) but is the mass distributed perfectly evenly? 🤷♂️ Again - maybe i'm wrong, maybe it doesn't matter, maybe it's good enough. But i wouldn't trust it.
He uses a four jaw chuck, which is common actually. Especially on huge parts. He uses the indicator and a hammer to true it to the lathe and dead rest. He realigns the two halves again on the lathe but with the metal hook looking thing and a hammer. Probably unbalanced as hell though and unevenly tempered.
Awesome work, master. Even those who work on fully automatic machines could envy your skill. respect 👍👍👍

Nice work mate. You show a lot of skill in all your movements.
Congratulations by your good job, I worked with engine's rebuild for almost all my life, and I never seen welding broken shafts, here in Brasil.
Fantastic craftsmanship this. Enjoyed watching this. I was on the edge of my seat watching this though, watching his sleeves nearly getting caught on the lathe 😮
Almost live leak. Gave me anxiety when I saw it. And so many safety issues. I hope nothing happens to this man. Hope things go well for him.
Guys calm down he probably knows very well what he is doing and what the risks are...better than you but thats just a wild guess. His sleeve was never ecen close to being "nearly caught", trust me.
It is a great and wonderfull skill .. but im confused, if the shaft break in 2, then you joint it as male and female, it has to be shorter than original length .. unless there is a step, to lengthen the shaft to deal with overlapping male female joint, which is not shown in this video ..
i am very curious how well these repairs hold up. my whole 47 years of life experience is saying this is sketchy as hell, using a pocket rule to measure journals......but at the same time, If it works????
fully tested the truck now holds 45 swammies hanging off the side, 30 goats, 500 bags of rice and 2 camels while driving up a mountain road sideways. ;]
Brother, this is high-tech, comparing to others who film this sh*t. He uses gauge, makes sure everything runs true in the lathe. Seems like he welded it coaxially, checked it afterwards. Plus these older engines dont require such tolerances as newer ones. So yeah, tools are crude but he knows what he is doing.
@@templar332 This is true. kinda why Id like to see if it holds up. Some of those other videos, holy hell man.

One upon a time things were repaired and not bought new and replaced. Sure the precision of the repair may not be as good as German engineering with CNC and laser measuring equipment, but it puts the dozer of truck back into service. What would you do if you owned a vintage car or motorcycle that broke the crank or spun a journal bearing and the crank is no longer available new or 2nd hand? Get it welded and machined down to size.
Always wondered how they get both pieces timed together, and get the welded journal straight and if it will last ?
Those machinists are trained well. When parts are expensive and labor is cheap, you fix it !!
Great Job. Thanks
He just put it back together at the break, u can usually get it pretty close most the time
It wont last long, the weld is softer than the steel the crank is made from so will wear quicker.
@@backyardbasher yes, but I’m sure it lasted long enough to get a replacement in the field.
@@backyardbasher See how many crankshafts he has in the background? I can guarantee you, he wouldn't have so many customers if they popped so easily, in a Low RPM diesel truck motor this should be fine.
Hats off , amazing work with bear minimum tools .not an easy task. Craftsmanship and experience. Very good job ended
Not knowing it would be impossible, he went and did it. Really incredible.
That's the key. "Realism" has gone to ridiculous levels and all ancient wisdom is being tossed aside as superstition. Basicly science religion has made it so that while most of the people think something is impossible, it is so and only very strong minded persons can dispell the mass dispell that is all around us. There is in principle no limits what mind can do if you have true belief in accomplishing something. Before Musk you could ask any top rocket scientists and they would tell you it's not possible to make a reusable rocket that can land itself whit its main motors. We could truly do wonders if people would not put each other down all the time, starting from kindergarten.
It wasn’t impossible. He also does this for a living. See all the crank shafts in his shop?

Unbelievable what a fantastic job! This is hard to believe 😮
كل الاحترام والتقدير لهذا المعلم والصانع. بارك الله في عملك .
Сразу видно руку мастера,удачи вам в вашем не легком деле
When cranks are ground (not machined) it is vital that the rod journals are concentric to the centre line. The fact that the crank was polished would kind of indicate they don't have a grinder and the crank was straightened the journals will likely have a slight taper. In modern computerized engines this will throw an imbalance code. It also may not turn when the rods are installed. 1 degree is huge and taking 0.010" minimum would help the rear match the front.
I agree with you 💯 percent, the guy has skills 👏, but that repair will have problems at the end
@@carlosmenard3926 We have encountered problems with chrome and spray welds delaminating also. Yes the fellow has skills, no doubt there.
Absolutely this was my concern as well. I would like to see if the crank will spin when reinstalled or if it'll bind up.
Super gut gemacht! Eine sehr schöne Arbeit!
Danke für das schöne Video!
That brings back old memories, I started out in a job shop doing similar work. The only difference is we had carbide inserts to use. I never really got too efficient at shaping and sharpening those old carbide and tool steel tools. I used mainly manual machines, lathes, mills, boring mills and an old Iron worker. We mainly made and repaired parts for the old Homesteak gold mine.
I bet you had OSHA and an EPA though lol.
@@94sn95gt yes, we definitely had that. This old boy would probably laugh at the rules we had to obey. Lol
@@stephenbloom2545 I use to make those cranks, 2 lathes and an end mill. Most of them were cast iron very few of them were steel. Those look cast to me so I cant see that weld holding up for very long any ways.
@@94sn95gt : The stringy chips suggest mild steel. Perhaps cast steel rather than cast iron.
He wouldn’t waste his time welding cast iron I bet , too much work at stake.
Great skills, the effectiveness of the repairs may be in doubt, but the skills are excellent 😊
I am a begginer Machinist, his job is Amazing
