BULL SHIT. WILL VIBRATE REALLY BAD..............................
If so, they won't do that, just waste their money and time
I guess the chains on the rod journals don't matter when you dump the crank on the floor after "fixing" it.
I was thinking the same exact thing!!!! 🤔🤔
Don’t forget the weld splatter all over the #1 main journal!
Well if it even turns when back in the engine, it will certainly totally wreck the rest of the engine when the out of balance crank flys apart, should be spectacular.
I'm surprised they didn't melt it down in a cooking pot, recast it in a bucket of sand and then shape it with an old cheese grater and a nail file
🤣😂🤣😂

Are you?
Fool me again? Another fake made for RUclips comments, is not a real repair.
Это для просмотра, лайки, комменты, вал лопнул это всё металлалом. Такой вал можно поставить на двс, запустить, даже по газовать можно будет
Se olhar o motor de onde saiu isso. A peça nova vale mais que o caminhão 😂
Добре колінвал фейк, але вони варять метал на токарному верстаті ! В них все фейк чи хворі?!
How would you know?
These guys have a good sense of humour. I liked the one they did on casting an alloy wheel.
لقد اختلت قوة الطرد المركزي بقدر الكتله التي اضيفت في مربع السرعه الزاويه وسيظه اهتزاز كبير كلما زادت سرعة الدوران مما يؤدي الى انكساره قريبا .
The main and rod journals have weld splatter on them and the crank seal surface is out at least .005 and the "machinist" gives it a thumbs up? CLICKBAIT.
spatter
Это нормально, они потом двигатель на земле, с песком соберут, и всё притрётся;)
And they'll use sand for lubrication.
The penetration on that weld was no better than a tack weld.
I feel like I just watched an episode of Macgyver! 😂
Let's just all it McFailure
트럭 30년 하고 은퇴했는데, 크랭크축이 부러진건 처음 봅니다. 얼마나 과적을하고 무리하게 힘을 줬으면 부러졌을까요. 파키스탄 영상에서 줄자 대신 버니어캘리퍼스 쓰는거 처음 봅니다, ㅋ
아크용접으로 크랭크를 용접해서 쓸 수 있나요.
금방 변형되거나 다시 부러질 텐데요.
금속 재질이 달라요.
Когда то работал мотористом в гараже.Так вот часто лопались наварные коленвалы-после ремонта наплавкой.А так очень редко.
난 엔진에 대하여 모르지만, 저게 버틸까요? ㅎ
Quebrou porque eles nao fazem virabrequim de aço 1045 forjado fazem de ferro fundido .ja fui em uma industria vi os moldes onde colocam tarugo no forno ate ficar encandecente ai coloca no molde e uma prensa tipo martelo bate ate ficar no formado .o dos barbudinhos fazem de ferro fundido .
А в конце покрасили с балона чтоб масляные каналы забило!
Его теперь на выставку достижений Пакистана. Больше никуда
Срок действия гарантии: до момента установки в двигатель.
До погрузки на машину которая его на сборку повезёт.
В промасленную лощеную бумагу его в целлофановый пакет и в красивый деревянный ящик, Ваньку какому нибудь в Россию пойдёт и уж потом пусть он ебе...я😅😅😅

А чё вы арёте... Именно так и выглядел ремонт во всём Мире очень много лет и на таких запчастях росли все современные города.

Great for foot lamp in a living room! But in action... Deadly vibrations! 🤣
If it makes it to the next town/village, they call it a success😁
Looks dodgy. The welding has undone some of the crankshaft heat treatment. An annealed crank might as well be made out of balsa wood.
Somebody doesn't know what annealed is...
@@Look_What_You_Did Annealing is the process where you let a metal cool down slowly. Which is what happens right after you weld the crankshaft.
Akward combination of Screw and Weld connections. Missing some superglue.
Never underestimate the power of a 7018 welding rod
The welds cool much faster than any annealing so they will be harder but also more brittle but good point never the same as original treatments
This is a joke . No way is this going to work. i bet it locks up in the block when main caps tighten up. if you even get main caps on.
Oh Steve do not get upset because your skills are not as good as a third world country ? You are the joke !
Why so negative? Go to Pakistan and the like and see for yourself! the ingenuity "necessity is the mother of all inventions" is mind-boggling. I've seen such with my own eyes. Low rpm is certainly a major factor for the survival of the repair.
One of the most astonishing repairs I ever witnessed was a long time ago when one could still drive without danger from Europe to Saudi Arabia or North Africa.
The father of a friend of mine had driven to Africa when one of the journal bearings of the crankshaft gave out.
No way to get replacement parts, or have machining equipment/repair shop.
A "village mechanic" with lots of ingenuity repaired it!
He saw that the owner of the vehicle had a thick leather belt and pointed to him that he needs for the repair the leather belt.
I saw the pictures.
What he did was cut out of the leather a piece the size and dimensions of the Journal bearing. Soaked it in oil for a couple of days and then began two assemble the engine. tightened the bearing caps and waited a couple of days, each day turning a crankshaft a little bit. Took it out again slightly sanded off a little bit of the by now all soaked and compressed leather in the assembly again until the crankshaft turned reasonably well.
It worked.
The man actually drove back to Europe and then still drove around for a couple years until he junked the car.
Out of curiosity the engine was taken apart and indeed one journal was an old by now blackened and hard piece of leather.
The crankshaft journal was polished like a mirror!
of course you need to know that this was an old four-cylinder engine with a redline of 3400 RPM and about 60 hp that barely got briefly Rev. over 2000RPM ever.
That's why this actually worked.
Ennesimo esempio di come perdere tempo e denaro inutilmente,sarà un miracolo se quel motore riuscirà a fare 30 km prima di esplodere...
🤮🤮🤮🤢🤢
Будет чудо, если проработает 30 секунд
Большое десятки биение и это возле центра , онже кривой писец. Этому колену дорога в металлолом.
ща в блок закинут на старые вкладыши и будут гонять пока опять не лопнет в этом же месте.
Да они просто прикалываются над нами. Просмотров много, много комментариев - им ютюб деньги заплатит за это 😅
Да ты что? Он почти новый! Ещё гонять не перегонять?
Притрется😉
Неделю делали и пору недель поездить..может 😂😂. А вообще жалко людей 😢
I admire the ingenuity. I wonder how long it will remain in service. Good luck.
These men are skilled in the trades and a disappearing art in this country. I can guarantee this marvelous repair lasted about instantly, or the mathematics indicates so.
EXCELLENT FIELD REPAIR. IT WON'T LAST LONG BUT LONG ENOUGH TO SOURCE A REPLACEMENT.
Those invisible steel toe work sandals are a must when working with heavy machinery and parts.
Heath Robinson would be proud of this 'get me home repair' . The crank will only shake as much as the last dial gauge reading, but not for long!!!!
Just look at the state of the bearing surfaces! They might as well use an angle grinder on them to remove the weld splatter. I give it 5 minute of running before it falls apart and knocks a huge hole in the crankcase.
Eres un maestro, aca en México, con una situación así solo se cambia la pieza completa, y tu la as reparado al 100, felicidades
The highlight for me was the black paint at the end. Going that extra mile distinguishes the precision machinists from the local hacks! 😁
Cringe worthy repair! I wouldn't even use that crank for a mailbox mounting post.
Yes you would😅😂😂
Ingenious repair, now the crank needs to be re-tempered if even possible, then turn it, balance it and even then probably wouldn’t last. However when you don’t know better or have replacement parts try anything to make it work. Here in North America the crank would be replaced with a good used or new one.
It's hard to tell but there's between 5 and 10 thou of run out, the big end journal is trashed and it wasn't re balanced. But I guess it will last just long enough to get the truck sold.
non accenderei manco il motore , !!!! solo su YOU TUBE possono parlo vedere , solo spettacolo !
Un cordial Saludo mis hermanos excelente trabajo y excelente reparación felicidades 👏 y le mando su poderoso like 👍. Bendiciones desde Monterrey NL México 👍
Esse povo são incrível , eles recupera tudo.
GOOD MASTER 👍👍👍👍👍👍👍👍
Impressive?....no, it's sad to see that some parts of the world have miserably failed to keep up with basic advancements in engineering, manufacturing, overall technological understanding....the list goes on and on. Yep, they make do,...and do well on getting by. Can't dispute that. It's still sad to see such struggle in this day and age.
These are the people who will adapt and rebuild human civilization after the next comet bangs into the planet. Low tech will be their salvation.
this is what happens when labor is cheap! If a crank is out of balance 5 grams it will never last. what a waist of time.
was it weight balanced ? is the surface welding good enough for where it was solid ? did the stress of breaking it made other anomalies to the shaft ?
Meu amigo sinto tanta alegria em ver seus vídeos e a inteligência que vocês tem. Adoro assistir seus vídeos. Aqui no Brasil essa capacidade não existe. Obrigado
Mejor amigo , sino tendrias una carretera llena de camiones rotos..
The machinist's 'Thumbs Up' is so convincing 😁
I thought the black spray paint .was a nice touch . Wonder how many were maimed in the start up ?
Good job
LOL... those scratches gonna eat your CR bearings in just 1 day 😂😂😂😂
I like the way they cleaned the weld spots off the journal at 26:17. Looks like a bit of file work.
The purpose of this video is that these people are more Resourceful then the people that comment negativity of this video great job 🤙🏾🤙🏾🤙🏾
Your work very hard and fine
Bet that didn't stay together long enough for the engine to finish cranking.
wonderfull
*I'm impressed.....how long will the repair last?*
Интересно, двигатель с этим коленвалом довёз хозяина авто хотя бы до дома?
Rear main seal face in the 4 jaw? no polish?
Waiting for the next repair of this crankshaft. Might take place on the following day.
apesar de ser uma bela de uma gambiarra isso quer dizer aqui no Brasil serviço porco mas tenho que tirar o chapéu pra eles, eles tem uma habilidade pra fazer uma solda impressionante parabéns,🇧🇷
How accurate can that lathe be if it’s sitting on a dirt floor? And what’s the deal with all the bolt on counterweights? Those deep threaded holes can’t be doing it any good as far as strength is concerned.
Grande maestro en occidente solobse compra la pieza nueva ,estas rompiendo los mitos al cual todos le temen ,fuimos criados para comprar cosas nuevas,. eres el mejor maestro del mundo mundial.
Perfect balance 😂
Great job.
USA repairs faster using duct tapes
I like how they torture the bearing surface with the chain, hillarious :)
Bound to run true at the end it was supported by the dead centre. How true did the rest of the journals run??
safety sandals 👡 , is it summers n winter use indoor outdoors as we'll
i wants to know how long that crankshaft lasted 😢
How hard would it be to cover the journals
Увидев это я чють не ослеп от слёз,молодцы умеют?

Ah, the old precision card board, with a hint of grit, little big of sand, a smack with a hammer, chuck it on the floor, and presto, Precision.
That’s cast for ya!
Good 👍
If it works it works . 💪
Lots of work, but that engine wont lasts long
На курсе у старика Станиславского они бы были отличниками!!! На серьезных щах сниматься в такой дичи, это не просто талант, это божий дар !!!
Apakah akan kuat dan awet...bagaimana dengan balancenya...
It’s unfixable ! It’s broke and is now Garbage….🤨🤨🤨🤨🤨🤨🤨🤨😤😤😤
You can’t fix stupid either…
Everyone commenting from all different countries, agrees.
This can’t be fixed and this is BS.
Best grinders of the World 😮
Not a real repair by the stretch of the imagination, I especially liked when he torqued down the 4-jaw chuck on the bearing surface, entertaining though.
У нас токарь даже на ломике носить валы запрещал, только на ремнях! Чтобы ни дай бог дотронуться до шейки вала!!! Тут, ребята, колотят по валу, варят!... Безобразное отношение!!!
Есть чему поучиться!!!! Пособие как нельзя делатт а надо!!! 😭😭😭😭👍👍👍
Amazing they always work on the ground. Did they never hear of a work bench?
What I find interesting and I never have seen before is the detachable counterweights, the latter not being part of the whole cast of the crankshaft. Must have to do that this crankshaft is being used with different cylinder sizes and displacement sizes.
Rapaz funciona. Já vi recuperar vira brequi. Fica top. Bom e novo. Quem não tem cão caça com gato
Вот это ремонт, молодцы, надёжно, уважаю. Гомно тоже становится привлекательным, если его побрызгать краской из балончика.
Это полный капец!!! Алибаба опять лепит на голой коленке!!!😂😂😂
สาเหตุเกิดจากชาร์ฟ อก ชาร์ฟก้านหลวมมาก
Так и не понял . В итоге эту деталь где будут использовать ? Явно не в двигателе ! Наверное будет экспонатом в музее ...
поедет лучше новой !
Глупая но хорошая работа.Такой коленвал только в металлолом.Но мастера работают уверенно-видимо это не первый коленвал.Значит такой метод ремонта работает.
но не долго. проще на соседнюю улицу оттащить, чтоб такой же из металлолома отлили.
Nope, will not last...the force is to the side, forcing the centre of gravity on the crank to widen the actual torque band. Plus using sandpaper to clean the journals is off-setting the bearing tolerances....Well, you get what you pay for.....
Quite a job. But it must be balanced, otherwise there will be strong vibration
پارك الله بجهودكم عمل فوق الممتاز احسنتم بغداد العراق
CNC master? I didn't even see any floor l would want to put a broken crankshaft on, let alone an expensive machine .
Warranty: 5km or 15 min. Idle (depending on what achieves first)
Instead of welding a reinforcement plate isn’t it better to hard surfacing it ..😂😂🎉🎉
Your solution is no better than theirs. Worse actually.
What was the welding machine amperage set at
😂😂😂😂
Looks good. Just wonder how long it will last?
About 5 minutes
What about the crack in the radius, thats going to last adout 2 min, i dont know if its going to break or spine the main or rod bearing first
The best Pakistani, goodjob
Thanks
Essa reparação não oferece garantia que resista ao mesmo esforço feito até voltar partir mas muito em breve.
Wouldn't it be totally out of balance ..?
de cigueñal a batidora manual o vibrador
رنگی که پاشید محکمتر از روشهایی که داد بود 😂😂
The cardboard trick makes them very professional and the jerky drill more accurate!
What a waste of time, energie and material!
What a purpose has this video?
They have a lot of faith
People don't realize that half of the overloaded vehicles on the road have similar repairs, and they keep going.
Nope, they haven't similar repairs. This crankshaft will not work. Video is shoot for youtube only - actually they will earn more money doing videos like this, than if they do real repairs for small payment.
Exactly, this crankshaft wouldn't last for long in an engine. Why they even painted the crankshaft, or what ever this was? I would be covered in oil anyway if this was ever installed in an engine :D
How on earth can they expect to get the crank balanced?
The guy next door has an old wheel balancer
