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.

this gentleman is an artist, all my respect

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!

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.

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.

Total respect for this man and his skills, what a good craftsman for sure.

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.

I am so inspired watching these guys work in hole-in-the-wall shops, with dirt floors, no HVAC, sandals and practically no safety equipment. It really amazing to see the craftsmanship. It also makes me appreciate how fortunate we are in the US...

Сварной шов просто песня, молодцы ребята трудяги.представляю чтобы они творили если им дать хорошее оборудование и условия.мое почтение, здоровья.👍👍👍👍👍👍👍🙂🙂

This is a guy that you want for a teacher. Nicely done.

Gotta give the guy props. Lays the cleanest weld I think I’ve ever seen.

This guy is an artist. Like most of the hard workers I’ve watched on your other videos. I love overcoming obstacles and making what you have work for you.

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.

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

Ovo je pravi i vrhunski majstor koji zna posao. Bravo covece!

Whenever there is a guy in flip flops and a welding machine I watch.. these guys are amazing

На все руки мастер! Сварщик, токарь, отлично работает с измерительными инструментами, да и в таких условиях. Во истину мастер!

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.

Nice work mate. You show a lot of skill in all your movements.

Tak tohle je teda fachman , to obrovský respekt. Strašně šikovný chlap, jsem od řemesla, ale takhle vařit kliku bych si netroufnul. To jsou sváry jak z automatu, opravdu se klaním.👌👌👌👌👌👌👌👌👌👌👌👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Looks like he takes alot of pride in his work. That is missing from alot of tradesmen/craftsmen these days.

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.

I was looking to put up a shelf in my house so I thought I’d watch this video for tips and skills, amazing craftsmanship

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

Imagine if this dude had up to date tools... You can't do any better with what he has. He's definitely got some skills

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.

Trabalho formidável! Se o fazem, é porque tem experiência e pode ser aplicado! Não fariam a montagem de um motor cujo virabrequim facilmente quebraria! Pelo que entendi, foram aproveitados peças de dois virabrequim!! 👏👏 Parabéns!!

Absolute RESPECT for what I just saw- I'm in awe.

AMAZING CRAFTSMAN.. what ever he charges, he deserves more! I hope he's told he got almost a million views in 11days.

Мастер золотые руки! Смотрел с удовольствием! Браво!!!

🖐️Такой труд заслуживает уважения 🤝

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.

Man knows what he's doing! As good a welding job as I've ever seen.

Insanely good! I've never seen anything like this before.

Hats off , amazing work with bear minimum tools .not an easy task. Craftsmanship and experience. Very good job ended

Nice work my father-in-law is a old time master at this stuff I’m going to share this video with him Bravo 👍

Very very few people can truly understand what dude did here. I am very impressed given what he has available to him. 👏

У него таких валов целый сарай. Сразу видно, что ломаются часто. А он их каждый день ремонтирует

Сварка по месту слома... Обработка шеек коленчатого вала напильником и полировка вала наждачной бумагой. Эпик!

كل الاحترام والتقدير لهذا المعلم والصانع. بارك الله في عملك .

Pretty dam good. You can tell this guy has done many before, and I’ll bet he wouldn’t be in business if his success rate wasn’t good. A+ for effort.👍👍👏🏻👏🏻

Pakistanies son geniales,arreglan todo ,con pocos medios tecnologicos hacen maravillas Nos dan una gran lección que con esfuerzo y trabajo todo lo repara,desde Chile un saludo a tan esforzados trabajadores espero algún dia tengan la recompenza por su esfuerzo Hacen mucha falta talleres Pakistanies por esté país

I am a begginer Machinist, his job is Amazing

What an incredibly brilliant Master Craftsman. Well done. 👍👍👍👍

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!

Ich arbeite hier in Deutschland an einem sehr modernen Drehautomaten bzw Drehbank und muss sagen besser hätten wir das hier auch nicht machen können. An einer Drehbank wie der gute Mann sie hat würden viele von uns kapitulieren müssen. Das könnte keiner von uns so gut machen. Leider gibt es hier nur noch wegwerfen und neu kaufen, die Arbeitsstunden könnte keiner bezahlen. Mein Respekt und meine Hochachtung für diese Arbeit.👍⭐⭐⭐⭐⭐

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 🇩🇪

Great skills, the effectiveness of the repairs may be in doubt, but the skills are excellent 😊

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.

Долго ждал когда будет шлифовальный станок. Угу, очень забавно, особенно шатунное шлифование😂

Simply amazing. Enjoyed jeffadams story to.

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,

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.

here in Italy, an advanced country in the motoring field, if I presented myself with a broken crankshaft and asked a mechanical workshop with cutting-edge equipment to repair it, they would tell me if I'm crazy. Probably a job like this will have been rewarded with 50 euros ...... a great craftsman.

yall do some amazing work with the resources u have awesome awesome

Это мастер с большой буквы! Уважение мастеру!

Unbelievable what a fantastic job! This is hard to believe 😮

This guy could make a fortune teaching aspiring machinist this method before moving on to all the high tech machines in use today. Great job!

Not knowing it would be impossible, he went and did it. Really incredible.

Самородки, преспособились, токарь колоссальную работу сделал и варит классно, в таких условиях не каждый сумеет,трудяги!

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.

Вот это спецы. Всего хорошего им настоящие трудяги.

guy is a pro !!! sharp bits, excellent welding , good Finnish

It's called makeing do with what you have. Hats off to the machinist.

Bonjour ces personnes qui réparent comme je l'ai déjà dit sont vraiment très très fort accompagné de personnes comme eux tu débute la traversée du désert avec un vélo de l'autre côté tu te retrouves avec un 4x4 qui fonctionne je dis cela pour simplement dire à quel point je les admire je suis abasourdi par leur maîtrise dû travail qu'ils font punaise que je l'ai admirent

Ένα μεγάλο μπράβο για την προσπάθεια που γίνεται είστε όλοι άξιοι συνχαρητηρίων

This is the first time when I watch these types of sketchy repairs that they clocked it out. I would actually like to see the sequel where the crank go’s into the engine.

I bet a Osha inspector is having a stroke right now 😂😂

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.

I mean, I wouldn't really want a welded crank in my machine, but damn... man does good work. Especially with what he has.

معلم وحرفي بمعنة الكلمة وبدون منازع 🇲🇦👍👍👍👍👍🇲🇦

Love how he lined up the journals with that bent wire.

Молодец!!! Теперь можно смело отправлять это чудо в пункт приёмки металлолома.

I have watched so many of these style videos and I love them. Bless this man for actually using a dial indicator to get everyting straight and true!

Great job man! I appreciate you!

Some of the finest quality welding I have ever seen. May be should replace the carpet slippers with steel toecaps.

Awesome work, master. Even those who work on fully automatic machines could envy your skill. respect 👍👍👍

Это же ненадолго . Так доехать только куда потихоньку без груза. Но за мастерство респект.

The pink "measuring twine" is classic. I made crankshafts for stock cars decades ago. Brings back old memories.

Смотришь этот сюжет и проникаешься огромным уважение к первобытным мастерам ,высочайшей квалификации.Вспоминается своя юность,история нашей страны.ПТУ для хулиганов,вечерние школы,заочное и вечернее обучение .Первая зарплата ,которую ты до копейки отдал Маме.honor and respect for people of labor.

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!

Сложную работу делаете. Удачи вам, братья.

Parabens pelo trabalho. Vocês dão o exemplo do que é ser profissional na profissão mesmo com tão pouco recurso para trabalhar. Simplismente magicos show 🙋🏻👏👏👏👏👍🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷

Wow absolute true craftsman wow awesome 😎 👍

always a pleasure to watch a master craftsman in action. He knows what he is doing and does it with half the resources of what I would expect and with great care to the end result.

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..

Geez, amazing run out achieved during setup... SKILL!

👍top machinist and precise.

As someone wrote in Road & Track magazine many decades ago, it's great watching a professional at work. (Writer was probably Henry N. Manney III .)

Они не на коленвалах зарабатывают а на видео🤣

Respect ! these guys are amazing !

amazing work!

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

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.

Beautiful repair; while it will never be new, it will definitely run another day. I can only dream of such skill.

Essa foi a primeira solda de qualidade que vejo desses homens que usam técnicas rudimentares

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!

Parabéns, serviço perfeito, excelente profissional

hell yeah brother absolute legend

حقیقتآ یک کار بسیار بسیار دقیق که حتمآ هم باید با دقت صدم میلیمتر انجام بشود و بسیار حساس است و درود بر شما .
