I am as impressed as I am appalled by what I have just seen.
no shit right, like WTF
Appalled by what? A man uses basic machine to do what you think can only be done by cnc equipment? How do you think cnc's were made in the first place?
I grew up with equipment like this and made everything needed.
I think the poster is commenting on the complete lack of quality control. In the US there probably would not be any shop that would perform this kind of repair due to liability. If somehow they did take it on you would see far more measurements, inspections etc. especially regarding the welding. This is to say nothing of the absence of any safety standards in the video. In the end it’s a question of what level of risk you are willing to accept. In the US that tolerance level is very low given the potential consequences.
@@hcderksenhe's not talking about cnc machines he's referring to fixing a broken crankshaft
@@RJ1999x well aware of that. In the old days this was all we had to work with. Folks are spoiled now.
Its nice work.. but for entertainment only this old crackshaft was not in use (rusted) and obviously cut with a cutting torch.😂
We need to see the follow-on video "first startup"
To be honest, I had a similar concern. If high-quality steel crankshafts break, how can repaired ones last long? However, since the mechanics charge for their work, and considering engine assembly and disassembly are labor-intensive tasks, they likely wouldn’t stay in business long if the crankshafts they fix break again within months.
*About 45 years ago I was in Columbia and we cracked a piston on a $2M CAT excavator on a mining project. I watched these backwoods mechanics sand case a new piston, machine it and it worked for 6 years before I left with about $25M in Gold and just left it the big CAT in the jungle where it sits to this day. It's amazing to watch stilled people working.*
You mean Colombia?
The word on the street is that crankshaft will never run in an engine again. This was just for views.
We somehow missed them drilling the new oil passage for that bearing.
Excellent point!
i think it is not necessary for two minutes until it breaks again or the enginine fall appart from vibrations...
I saw a through hole that would have fed the passages up through the counterweights. Hope they use a new oil pump!
There will be a guy with an iol call pointed at that bearing, he will also have a net to catch all the parts when it grenades
First thing l noticed also. I spend a chunk of change getting my race motor machine work done now but the new one l'm going bore out with a cold chisel, balance the crank with two nails, rope and a horseshoe then button it up with cereal box gaskets. (Spray the head gaskets with Copper-cote because nothing to good for my baby. Let it eat!
Wow, these guys do not waste anything in their shop, amazing workmanship on display.
I love the way they machine this stuff like it is a piece of machinery from the 10th century!!!
It's a lathe, millions of them almost just like that one spread across the US.
taught by us mate,,british engineering.. the best.. or they wouldnt have a job..eh..
@@harrywalker968 I believe that, kidding aside, some of the stuff you guys came up with during WW2 was nothing short of amazing,ive always loved that story about Radar and that quote "The Germans could never figure out why the British fighters were always waiting for them when they got to the coast" ha ha ha ha
All this work and no carbide inserts. Just hand ground cemented carbide and high speed steel. Amazing!
It's so important to be able to repair anything when in need, even if it's just for the time-being !!
Curious, what makes you say that ?
But the crankshaft will never fit into the engine block. Let alone the fact that they now have no oil going to the rest of the crankshaft. Like I said, I know it'll never fit into the block, but if it does, the timing will never be correct for the cylinder firing because they never put it in the proper rotation.
I'm an old school type of guy, I try to repair whatever possible, before having to buy anything new, and because I'm inclined to do so, I saved some money, but I was also able to make temporary repairs, and for example continue my road journey, or even better, save costs not having to buy new parts, by being able to make permanent repairs without buying new parts, but it's getting more difficult to do that for many of us, as things are more complicated, less durable, not made to last, and even labour costs is getting more expensive, and replacement parts are in average cheaper, and easily accessible.
PS, I don't thing these guys have shown the finished product, some are saying ''''ít won't last, it won't fit, it'll burn out, because it doesn't have the needed oil channels''''.... whatever, I think these guys are smart enough to know that !
They do what they can to survive, what else could they do ?! Better that, than not being able to pay for a new one, just sit there, do nothing and starve, because they have no other options ?!! No right ?!!
@@stevenhorne5089по-моему они и не собираются устанавливать коленвал в блок двигателя,это сделано только для Ютуба.
@stevenhorne5089
EXACTLY!!
Safety is #1 priority with these guys! Pretty amazing the skills they have and they still have all their digits!
I helped a friend move everything in his house and I was wearing sandals. I wouldn't recommend doing it though. I managed to keep all my foot digits but I guess most shoes don't protect that well anyway not when it comes to heavy metal objects. @@hundredfireify

I held my breath when he was holding that rag to wipe the journals down while it was still running.
I love these videos, reality of solving the problems to keep the world going, good job!
Даже не думал, что такую поломку коленвала можно сделать, однако факт на лицо, перед профессионализмом мастеров снимаю шляпу, молодцы!
Well I was drawn to the video by the two sections of crankshaft, and knowing the ingenuity of these chaps, my first thought was how were they going to align the shaft at the correct angle. I was thinking that they would set up a jig of some sort. Holy moly - got to the point where they were bashing it together and eye balling the fit whilst almost making a pan cake of ones hand. I seriously had to rewind as I couldn't believe it. So I suppose when you time the engine, you time it with the crankshaft with the most journals and don't worry about some minor detonations from the others. I imagine the noise from the bearings looking at the state of the other journals will mask the sound.
Absolutely love it. Can't wait for the next video!
Good job my friend...🙏
По коленках кувалдой... и фазы на глаз выставлены.... супер ремонт... а шлифовка-вообще класс!
Нас ждёт то же самое. Осталось с китайцами разосраться.
то что при проточке подставка упиралась в коренную шейку это уже мелочи)
А какие шикарные масляные каналы в шейке просверлили? Любо-дорого смотреть! 😉
@@user-sn2um4ij5nчертов идиот
I am impressed at what these guys are able to do with the equipment available, and under the conditions they are left to work in. No multimillion-dollar CNC, just ingenuity and can-do spirit. Yeah, we did not see a new oil gallery being drilled. Maybe that came later. Maybe the crank it will hold-up under load. We’ll never know.
You didn't notice how the "repaired" journal is twice the width as the rest. This piece of trash isn't going back into an engine. It was made for CZcams clicks and Neanderthals like yourself...
According to people in the know this shaft will never work in an engine again- no oil gallery, improper alignment of the piston journals, etc. This is just for views.
Это называется *еб@нутым нет покоя.* Es ist billiger neu zu kaufen.
ABSOLUTELY WILL NOT EVER WORK! Besides no oil gallery and not aligned but it's out of balance as well! STRICTLY for views! Tbh, I wouldn't have posted it!
Did you see it run?
Gotta love the safety sandals!
Open toed safety sandals are the best! 😉
I love their safety shoes!
The Worker at the Lathe is a magical Artist ! Incredible ! 😂😎✅
Very nice beautiful good job 👍
Да они так , для рекламы снимают . Видно же что шейка газом перерезана была .
Какая-то антиреклама получилась...
@@user-ys3jy1iz8k Мол , смотри как можем ... )
Газом порезано возможно потому что из двух порванных колен делают одно.
Just amazing
Amazing, looking at the journals on the crankshaft I wonder if it was worth all that effort. I can't see this lasting very long !
Finally, somebody else saw what I saw. I'm not worried about this engine lasting 10 mins, because I don't think it would even line up well enough to get the bearings on or the pistins in!
Maybe this done just for views
beau travail et bonne idée de "recycler" certaines pièces pour faire les réparations, j'ai été dans le métier et je vous dit excellent travail ,je vous souhaite une bonne vie ,mes amitiés👍🙏
Using the blue rag in hand on a spinning part had me wincing. The death grip he had on his sanding belt had me concerned too. That sort of thing can bite and grab in a blink of an eye, taking you in with it. :/
They have a six sense very well developed .
There are videos out there of people getting a broken arm to being killed from doing that. Its not a question of if, but a matter of when.
@@bobsbillets8863 I do believe you.
even better, he has his back against the wall, nowhere to run. The lathe should have been turned the other way. Talk about ingenuity!
@@bernardmauge8613when the lathe attaches itself to you it won't matter how it's situated and good luck running with a lathe eating you. Reality is something will be missing, finger, arm, life, all of the above.
Я лично так делал 2 раза и всегда выкидывал. В чермет.но видео познавательные интересное .
ВИДИМО ТАК ДЕЛАЛ....
Почему два?
С первого раза не поверил?
@@Anton..A
Второй раз болие качественно ,от безделия
This is ingenious.👍👍.
Nice boat anchor
😂
I think the comments are from people who do not understand that,all these journals should be concentric and square to each other The originals will be ground "in situ" on a cylindrical grinder then balanced to stop any vibration caused by run out Would be nice to see the inspection report on this part 😢
LOL!!! A 3 jaw chuck that looks like its spent 10yrs dragged down a gravel road, over ways that have NEVER seen oil, w/o a single micrometer or indicator in sight, thinking this "repair" is anything other than a 3rd world goat screw indicates the person has no idea what they're talking about.
None of this makes any sense. They're not measuring anything. They're probably illiterate, but they know that they're supposed to measure something, so pretend to do it. It'll never fit in the engine block because they payed no attention to the width of the journal. What baffles me is that so many people in the comments think that what they're doing is a good idea and some how they're saving money. BUT IT'LL NEVER FIT IN THE ENGINE BLOCK!!
What does concern me is that the unbroken crankshaft probably started out as a one piece forging. I don't think it was likely cast, but I can't say for sure. Now it is two seperate repaired and joined pieces. I am not sure what kind of service life it will give after the repair, no matter how well the rest went.
Even if it was ground correctly that crank will break again almost instantly. You have no idea how much of a shock load is on that diesel crankshaft when under a load. There are so many issues with doing this!
@@bobsbillets8863 Oh come on. 18:1 compression ratio barely stresses a crankshaft.
HAHAHAHAHA
Amazing work, what a fabulous job they made of this and it being dangerous work with the weight of that shaft spinning, and when the mechanic was putting the rag around it I was concerned that the rag could have got caught up and pulled his hand into the spinning shaft!
So very well done Folks, totally fascinating and skilled work!
Safety sandals will negate any possible disaster.
Unbelievable and amazing
And... you gotta love those highly protective welding helmets!!
Watch you guys all the time. You're really amazing. When I had a shop, if something broke, we just replaced it. You guys think waaaay different than western minds!!
Gotta love the safety sandals!. The polishing rag process got me cringing.A brave man indeed !.
Estoy estufefacto, anonadado, sorprendido what a job guys you are the best!!! 👍👌
No creo que Dure mucho ese asquero cigueñal soldado 🤣🤣🤣🤣🤣🤣🤣🤣🤣
Surreal ótimo trabalho!
I really appreciate the ability of this machinist, if it will last is another matter. Great Job.
Excelente trabajo mi felicitaciones Dios te bendiga y te cuide y te proteja siempre te siga dando mucho salud y vida saludos ojalá aquí en Venezuela hicieras ese trabajo
Обратите внимание на 11:25. Там видно дырку при отливке вала, и там ещё проскакивают, ну вот его и сломало. При соединении частей кувалдой, скорее всего есть смещение углов, и как следствие балансировка слетела. На холостых если работать будет, можно продать как с разбора. Главное покупке видео не видеть
Superb

Fascinante el trabajo,aca en España ni pensasamiento en hacerlo.gracias en ponerlo en video🐑
Race ready! Dude could definitely do work for Roadkill Garage.
I am impressed at this pantomime of a performance. We all know this crank won't ever crank again but we still watch hoping for a liveleak accident.
¡¡ESE ES UN MECANICO CON MAYUSCULAS !! 👏👏
Ich kann mir nicht vorstellen, dass der Rundlauf im Dreibackenfutter auch nur annähernd genau genau genug ist.
These men are truly gifted machinists!
Excelente tornero espectacular te felicito 👏 👍 😉
Good job brother well done
Eyeing up the journal timing...............now I've seen everything!!!
Don't know how many commentators have ever ground a crankshaft, but that is difficult and precise work. Pieces are ground so that hard spots that are high spots don't become hot spots. So this was not ground, but turned. it will not be as smooth as it should be. So for as good as they did, I see it wearing out bearings in short order, If it should survive.
At the beginning of the video I was *amazed* at the force it must have taken to twist apart [that huge crankshaft. I couldn't image how he was going to connect them back together. Then I was puzzled at the slap-dash measurements. But the fit was tight. How was he going to align the two parts? And how could they possibly be secured against the force that snapped the original? Then he seems to have aligned them by eye, and finally he stick-welds to bridge. [Throws up hands in disgust] Well *that's* 30 minutes I'll never get back!
it's been cut with acetylene.
Amazing!
I have a lathe had the hardest part for me is the precision necessary sometime. A beam capaliper is not that accurate and the one the machinist used was not digital. He read it with amazing speed! He breezed through the setups but aligning the parts in the lathe would have taken considerable time and with the beam micrometer getting the accuracy needed would have taken days! I am not sure how he aligned the two ends of the crankshaft but it usually takes a lot more precision than standing back and eyeballing it!.
I have watched other videos on CZcams showing people manufacturing many things without the use of high tech Digital techniques . or equipment. I guess no one told them they couldn't do it so they just didn't know. Human ingunity is amazing!
Because he KNEW the arror that the caliper intorduced and accounted for it in his machining. This is what a TRUE Engineer looks like when he's working.
Necessity creates solutions and in this case it was probably this or nothing specially living in a poor country, but the bloke did well very well how long it will last?
@@Choober65 That’s not engineering; it’s bodging. Not saying it can’t be successful, but odds are this goes into an engine rebuild where the customer has no idea what he’s getting.
Note that the crank is polished to it's final dimension. As long as that caliper got him within .005", he's golden.
Leland - Depends on the tolerance of the original design. Old engines designed before the micro-machining age were quite a bit more forgiving such as with Model T Fords where you could deal with most machining with a large electric drill often suspended from a big spring. Seen farmers in New England soap up some blocks of wood with v-notches cut in them to turn and true cranks without a lathe. He did use a dial indicator to true it up in the lathe and likely left out some of the finer details of double checking the timing. Introduce the first few thousand miles of wear when setting the main bearing clearances and you'd be surprised at the results even if it wasn't 100% perfect. Perhaps it will only last 60,000 to 80,000 miles afterwards instead of 90,000 to 120,000 however the vehicle its going in may not have much more than 50,000 miles left in it anyways so why invest in a 120,000 mile engine repair?
Sometimes though its amazing what you can do when you haven't been taught/trained that its impossible. A lot of drowning people who were goners in hopeless situations somehow survived because they didn't know their situation was too hopeless and futile to even try.
Best!
good job
Excelente trabalho parabéns
I have seen a lot of weird things done to a crankshaft but this is a first. I certainly appreciate the skill of the machinist but I really wonder how long will it last. in any case this is a manifestation of the saying: necessity is the mother of all inventios.
I bet the very first power stoke broke this thing.
@@hedunlap It's a low-rpm diesel, you're going to lose that bet.
@@TheRealCheckmate No... Torque is not what breaks cranks. Ever broken a crankshaft? I have...
@@poopy_pants_joe1194low rpm would be worse, half the speed twice the stress on the shaft, rpms would be his friend
@@RJ1999x No... revisit crankshaft harmonics. Cranks break due to stress reversals, when you increase RPM, you increase the number of cycles.
Wonderful.
I liked the "eyeballing" the timing of the two "reconnected" parts of this Wankshaft !.......................................
Doing such a precision job with a tape measure and wire hanger is insane
Very nice
I appreciate how the machinist found some high strength steel for the repair, but how can he manage to maintain the tight tolerances demanded by a crankshaft ? Perhaps not as good as new, but good enough to get the driver back on the road earning money !
Reality is they don’t maintain any tolerances. However for that society and culture there are no expectations of quality or length of service for tgst crank.
That’s second and third word culture and economy.
@@TheMilwaukieDan .It's a warrenty repair, 500 miles or 5 minutes which ever comes soonest .
This is not a strength issue, this is a stress issue. As long as the repair last longer than other unrepairable part or the whole truck
Ответ простой. Никак
Looking at the state of the big end bearing surfaces, the repair is probably the closest to tolerance of the whole crankshaft. Brilliant work with simple tools.
I didn't see them drill an oiling hole for that new journal.
My thoughts exactly.
Didn’t see any alignment of the crank throws either - he just eyeballed it. No splines cut to give the joint strength; just a circumferential weld to handle all that torque? It’s absurd.
No one else in the world can do this repair job better than you do. Very impressive.
LMAO
Because no one having a smallest signs of intellect even in a deepest dementia would not allow a thought about doing anything as stupid as they did...
Really amazing
Super depar yaar 😮
We fail to realise that our throw-away western world doesn't extend to the rural sub-continent of India and Pakistan. I have seen entire truck engines stripped and rebuilt at the side of the road using methods of improvisation that are truly inspirational. Even if this crank only lasted for a few hours, it may have been enough to get a heavy and valuable machine back to a place where it could be repaired or repurposed.
i like this engineer and safety horror movies :)
300 полуляхов из 300🤣
good work boys!!! I bet that truck will make it at least out of the parking lot
If this guy's ha ve a hammer. They fix anything, good job guys!! 👌👍🙏
Các bạn quá giỏi 👍👍👍👍👏
How did they set the timing on a crack through and I forgot to drill and oil port for the main bearing
Yeah it's sketchy but we all watched to the end. Plus have that thought banging around "wonder if it works and for how long". 10/10 on entertainment value alone!
Vcs são ótimos nú que fazem,,,,, parabéns

Wow Video
Wow!
That was a fantastic job. And it probably cost less than having your tyres rotated in the US.
Well, they passed the savings of no shoes, eye protection, any semblance of precision measuring tools, using only guess-ta-ment alignment on to YOU! I'm sure their warranty goes something like: if this repair breaks in two, carefully collect the pieces and we'll try it again for less than a tyre rotation fee.
Maybe it cost less, but for sure it doesnt meet any of the manifacturer standard for the part.
It will never work. It won't even fit in the engine block. If they sell this, they're stealing peoples hard earned money.
We don't have tyres in the US.
@@hedunlap So what do you call the inflated rubber thing that fits onto the wheel rim?
Amazing I’m worried about his safety boots 😳
Glad to see they cross drilled it and heat treated it😂😂😂😂😂
😃不錯的方法，😅但二個相接，🤔確定二者曲軸角度正確嗎～
😆不要到時裝到引擎，造成引擎活塞做動，讓曲軸角度有差異造成引擎大修報廢🤣🤣🤣🤣🤣
These videos are entertaining,my father was a overseas worker so i grew up in places like this, reason people do these things is because they have very little resources,they cannot find another piece so they resort to these "repairs", sometimes they work and sometimes they dont,for us Folks lucky enough to be living in the USA,UK,Germany and other places like that we cringe when we see this stuff but believe me, to them is perfectly normal,we just get on our cellphone and call any place that sells cranks and order another crank,300/1000 bucks? no problem,send it UPS overnight and all is well.
This looks like a big diesel crank,i actually work in machine shop and we only deal with big stuff, cranks that are 10 times bigger than this,50 feet long etc, most cranks when they break like this is game over unless they are something extremely rare and worth fixing,thats another point, is it worth fixing? a small block
Chevy or Ford or even big block you can throw away,a Bugatti crankshaft or one from a Ferrari Colombo or Lampredi V12,yeah you wanna try and fix that!
One of the reasons there are still so many good condition 50s cars in Cuba is because those folks have had to do the same these people are doing, not sure why it say United Kingdom in the video description, this is Bangladesh or India or one of those places.
This is Pakistan,Pakistan ... Not India once upon a time we were repairing crankshaft. But now, situation is different.
Your explanation is absolutely correct.

An excellent job if I say so myself
Süper love Maşallah lakuvvete❤
Everyone watching says it will never work again etc etc. I don't have experience with these type of repairs. I, like everyone else who's repaired an engine failure, would turn that crank into a boat anchor. But I have travelled overseas a lot in poor countries, and the amazing thing is, they do get this stuff to work again. Maybe not like a new engine and without the longevity, but long enough to continue to make some money. In Australia, and possibly the US, during the depression, stuff like this was done and they were known as 'bush mechanics'. Farm machinery and vehicles were kept working because nobody had any money to replace it.
I like the eyeball register of the crank throws, how long will it last in use I wonder?
