Watching this video I'm really surprised they are looking after their Lathes because everytime any welding is done you never see the earth clamped to the part being welded so that says to me that they have just clamped the welding earth to the bed of the machine, if that's the case then it won't be long before the headstock bearings will be destroyed because when the arc is struck it will be marking the running surfaces of the bearings so it can make a circuit and with the bearings running in oil it will be damaging the bearing surfaces everytime the make a tack weld.

I agree that there are alignment concerns with the crankshaft job. Overall I give them 9 out 10 for their craft and their problem-solving skills. In parts of the world where auto parts may not be that readily accessible or very expensive for a small farmer, we learn to appreciate this kind Trade.

Thank you 🙏 impressive work ☝️crankshaft 👏👏👏👍🎥👋☮️

Vcs estão de parabéns vcs e o cara aqui no Goiás não tem igual a vcs não aqui quebrou joga fora tem tantos torneios mais........kkkkk❤❤❤❤❤❤❤

43 years ago I interviewed a machinest who'd been recently laid off after many years of faithful service in a Boston area company. He explained his loss. Vietnamese immigrants who came here were hardworking and quick to learn. A manager asked his machinist to show one of the immigrants how to do simple jobs on a lathe, which they did. The Vietnamese were respectful and hardworking, but they were also very familiar with hunger and insecurity. The jobs meant a lot to them, and they worked very hard to please the people who signed their checks. They worked with out breaks. The experienced machinists were let go. The hourly wage difference was the reason. That lasted until new jobs came in that required a different setup, and the managers had no one who knew what to do. Shortly after that, that, company went out of business. A costly savings in a manager's quarterly report was more important than the company's survival.

Looking at what these guys have to work with in the tools category. I marvel at the precision they can still get.

Muy bun trabajo👍👍👍👍👍👍 Esta muy bien hecho👏👏👏👏👏👏

Missed opportunity to bump the compression up a bit, now you don’t have to worry about clearances for valves. Really awesome build!

1st Video. Crankshaft repair. After the repair, there is no oil hole in the journal that must supply that main bearing with oil. All the other bearings after that main bearing will also be starved of oil. I bet it wouldn't even last 200 revolutions without oil. Another boat anchor.

Nagyon szuper... Gratulálok.

The first shop was incredibly well kept, and the machinery was immaculate. These guys do amazing work!

On that crank welding video that engine would never run again after that repair, i didn't need any Dial Test Indicator stand with a bit of pointy wire on it to tell me that No1 and No4 Conrod Journals weren't in exact alignment 😂😂

I call B.S. on the crankshaft repair ! Good initiative but not knowing the correct timing of the broken shaft to begin with it is impossible to just weld it back together in any order.

You are amazing the best work ever seen very great 👍👍👍👍👍 I give you five stars ⭐⭐⭐⭐⭐ love to see more

Brother I just wanted to say what an excellent job, you are first class all the way if you only had modern equipment you would be KING!!!!!

De verdad los felicitó por su trabajo aqui en venezuela nunca a vido un tornero que logre este ojetivo yo como mecanico nunca e mandado hacer esos tipo de trabajo por wiempre dicen que no queda bien

Не ну с коленвала я долго орал🤣🤣🤣, тут походу после такого ремонта успеть машину продать!!!

amazing video, thank for sharing

jestes dobrym fachowcem , tylko mogbys czesciej uzywac czujnika

Думаю что это делают ради просмотров, для зрителей, потом после ремонта этот коленвал выбросят на свалку.

Eu acho essa profissão muito top parabéns ao profissional

Excellent job under, by Western standards, somewhat primitive conditions, Full marks to these fitters. I did not see how they aligned the Rod Journal Throw before welding. Great work though lads. Cheers from Michael. Australia.

Сваривать в станке? Странно, как им не жалко ни направляющие ни подшипники?

Me encanta estos pakistaní como se la ingenian para reparar todo ❤

way to go good engineering no proper tools basic skills we a[[ need to learn awsome people we need to give these people respect

Токарка и электродная сварка творят чудеса

muy buen trabajo y muy buen profesional

Excelente video y muy clara la explicación,,,

У индусов нет страха перед законами физики и механики МОЛОДЦЬІ

There is a very big risk of arc welding causing significant distortion. You will need to find out what weld preparation is required to get the necessary penetration. The electrode that you use will have to be matched with the crankshaft metallurgy, and there will have to be some sort of preheating of the crankshaft to minimise any chilling effect of the welding process. All in all, it would be a complex process, not a simple one of pulling an arc and welding it together.

first time i ever saw some one in India use a center drill. Never see a indicator or a live center. I would imagen they would be fairly cheep there. It would make there life so much easer. it is amazing what they do with what they have.

Ээээ 🤨 Это же не настоящий ремонт, они все это несерьезно, просто шоу для ютубчика. Ведь так... надеюсь.

It's the 3rd time Mr Jalin Rabei welds this crankshaft this year.

С помощью топора и сварки ремонтировать высокоточные детали? Это жопа. И как надо ездить, чтобы их сломать?

Super top parabéns gostei 👏❤

As for me, I will wake up tomorrow morning, exercise and appreciate life for the wonderful blessing that it is. I hope you do the same and have a great day too!

Vilão antes desmontar tinha que por um pneu top e rolar uns desafios , projeto é top e tem história , depois depois golf rs

Они щитают это норма но это низ технологий

How do you harden the weld that you use on the crankshaft or do you not bother about it.

После сварки , через 10 часов лопнет ещё без нагрузки

По коленвала видно что это уже не первый ремонт. (( Торсионная нагрузка на сварной шов, да ещё со стороны маховика(((

интересный ремонт при дороге коленвалы ковкий чугун полуоси цементированные ему надо термопечь купить и станок точечной сварки наплавки в россии кулибины так не делают не портят металл народные умельцы и у нас токаря и фрезеровщики имеются в стране но индусы предприниматели конечно страна огромная населения как муравейник запчастей нет и поэтому все приходится реставрировать экспериментировать .но у них много трициклов и минитракторов производится индусы любят мотоблоки и на них катаются как на мотоциклах.да индия экзотическая страна .но индусы уже свой танк сделали испытали и ракеты учатся делать .у них от английских колонизаторов много чего полезного осталось да и советские инженеры им помогали создавать индустрию.

I like video, interesting, and without advertising.

ich habe am anfang nicht verstanden warum ich gute noten beim schweissen bekommen habe. es war einfach nur das vorher saubermachen und nach anblick des schmelzbad schweissen...oben war die naht nie perfekt, aber das röntgenbild war solide

You have to wonder if that crank shaft had a bearing oil hole at the end it sure didn't show one when he was finished and so is that engine if put back together that way with no oil to that bearing, lol.

Nice ❤

Engine work is an art but people tend to think everything needs to be built to aircraft/Formula 1 Racing standards, but these guys do this day in and day out, so it must work. Props for working with what they have. Great content

I can’t see that crankshaft staying together

😮 Sei BRAVISSIMO

Optisch sieht das ja gut aus aber haltbar ist es auf keinen Fall, bei der Reparatur der Steckachsen hält ja nur das bisschen Schweißnaht das ist ja nur ein Bruchteil der Originalstärke. Bei der Kurbelwelle genauso das kann nicht lange funktionieren. Wir haben sowas auch gemacht aber immer versucht so weit wie möglich Durchzuschweißen . Aber trotzdem Hut ab was die so alles reparieren.

True professtional.

Muy Buen video good job buddy I'm very proud of you

C’est excellent 👍👏🏻

Коленвал сваркой??

52:36 If he had been able to use spray welding, could he have saved a lot of time and maybe money, but great job!

Mantap asli gais❤

mantap bang

Buen trabajo felicitaciones

Nice👍👍👍👍🔥🔥🔥🔥

E verdade que o pião come a coroa 👑😛😛🇧🇷

I'll give them credit for being willing to try anything. I want follow up reports from the users.

Yor video is very good

Скупой платить даже не трижды, я видел типа этих работ в Азии от нищеты они идут на такое и это работает только на то чтобы семья немножко ела и копить до следующей поломки вала на том же месте если повезёт, а так блок пробивает после такого ремонта, а впрочем они и блок проваривают

Very Good job!

Thanku

Чугунный вал сварить электродами по стали? У Вас вообще специалисты имеются?

Very skilled if the repairs hold up . But no safety classes and long sleeves very dangerous more than once I’ve gotten hit straight to my glasses with hot steel chips 🙏

Crank shaft made from gray cast iron. How do you machine gray cast iron? You can grind gray cast.

Для более про,ности ещо режется резьба более плотная резьба и ту чмсть где внутренняя резьба нагревают и накручивают три остивании она прихвачивсе ся а потом обаривают резьби режутся разние в зависимости от наорузки при вращеннии если вал правого вращенния значит одна резьба левая вторая правая , єто как в вашем случаи со вставкой ,а если из двух валов то нагузку назакручивание

I like your content, but your hollering voice, is rough to listen to. Thanks for your video.

Earthing that crankshaft thru the lathe will play havoc with its bearings

Todo muy bonito pero esa flecha aqui en Peru la tiramos a la basura, saben porque? esa flecha esta hecho de un material muy duro pero cuando le aplicas calor como con la soldadura este pierde su dureza incluso es mas quebradizo, se va a volver a romper esa flecha mas temprano que tarde jejeje

ع سلام خوبی عزیزم 😢من بخیر خوب است که در مورد 👨‍🏭ظفر و به 😮

The video is just for the show. You couldn't possibly use those part's again 😂😂

he is welding with rutile , is not correct by engine part

Chip makers ,that's it !!! and an intermediary who fills is pockets .

Молодец

Those guy would be unstoppable if they had a press.

Pienso que la que no hay una soldadura lo suficientemente fuerte para soportar el torque tan fuerte que hace el cigüeñal. Seguramente se volverá a romper en el mismo lugar.

never set timing for 1 & 4 rod. i can see it is not straight, you will never get 4 to fire on timing

that driveshaft will undoubtedly work until the first time a real load is put on it...

that crankshaft will work for about 10 seconds, if at all. they welded up the oil passage....

That crankshaft repair was precise! NOT!!

cooling...

How come the cutting blades are brazed on instead of just welding them on

Сдаётся мне что это была комедия😂.ачтотак можно было?

Not going to finish it I have heard of this but never seen it done and work you ibolt crank in won’t turn

How about indexing the crankshaft and no stress relieving?? Hmmmmm

Eyvallah.

mui buenooooo

Love these videos. We tend to judge harshly using western standards and it’s not fair. The innovation these guys show to get stuff done is humbling at times. The old adage “necessity is the mother of invention” was coined for situations like these. I’ve actually learned several things by watching and that’s the point for me. I can do the job better as I have better tools, equipment, materials to work with but learning the basic concept and not over complicate things. Just like anywhere else there can be quite a difference in work quality too. Another thing is safety or the extreme lack thereof. It’s definitely cringeworthy to see some of the things they get by with.

Welding a crank will not fix it, they will re weld it again in a month. Welding is not a fix all. These guys will weld anything back together. Just insane but I guess more power to ya.
