What a professional. Notice how he takes care of his equipment. He wipes, oils and cleans the ways of the lathe. Keeps it clean, chips are cleaned away. Every tool is cleaned and at the ready for maximum efficiency. No wasted steps or motion. Even the welding rods are neat and ready. A true professional craftsman.
do you think this is safe?
@@sopit666 He still has 2 arms ?
@@arcadeuk I agree with the work they have done, but do you think this is safe on the road? I have seen some accidents done by this kind of work. I'm not trying to downplay their work but I don't think it's safe to just do this kind of work.
All that but no PPE. Bunch of fucking cowboys
@@robp418 as a welder, machinist, and engine builder, I can say i am really impressed with this guy's craftsmanship. that is some old-world craftsmanship. not wearing safety glasses while running the lathe was a common thing before OSHA and all the safety regulations that were implemented after. but this not the US or even the EU or Japan for that matter. they probably don't even have an equivalent of OSHA in his country. personally, I would never turn something on the lathe without safety glasses or weld without gloves. this kind of thing was done in the US all the time until it got cheaper to just replace the parts with new ones made overseas. but in a large part of the world, they still do this kind of work.
I like this video, because it isn't overproduced. No annoying commentary or music. Just the sounds of the shop. Good stuff.
One thing's for sure, that man can weld. He's damn good at every step, actually.
downhill welding is easy as fuck. Doesnt take any skill tbh
ViralVirgin post a link to your welding videos.
Whats even more impressive is that's not even a welder... pretty sure it's just a re-purposed transformer :O
But how's the guy afterwards who does the oiling hole? LOL he needs to up his game.
@@dons1932 His name is Drilbo
WOW! As a Tool & Die and Mechanical Engineer I can say without doubt that this dude is a true machinist and old school skilled at his trade. The equipment and tools he's using are simple old and cheap. Goes to show that with madd skills you don't need the fanciest CNC and precision equipment in order to accomplish precision work if you know what the F you're doing. Extremely drawn into the video and very impressed. Oh.....and let's not forget to mention the guy can weld! To keep that big crank straight and true without is coming out a curly cue spring was mind blowing.
Where can I hire 30 of these guys right now in the U.S.?!?!
Gee we
The thumbs up after centering, following by cigarette-in-mouth machining lets you know he's done this before :D
To answer your question...you can’t and never will. But is suspect you already knew that!
as a mechanical engineer you have zero clue what you're talking about. I'll trust a machinist or welder over you any day you button pusher
@@Vtuned bet you could weld that crank too man. I’ve see your skill!
As an welder myself i am just soo amazed how good this work was. Welding that cleanely and then knowing how to it without it getting crooked from all the heat with just supports at the ends is just amazing. Truly a skilled man there. I cannot think of anyone would do this kind of repair work in europe. theres so much that can go wrong and is time consuming. now this guy probably did the crank in an hour.... :O Respect and hats off!
It did warp, around 27:00 he's using a hydraulic jack to bend everything back in shape.
You can't teach pride
Only thing it wasn't 100% true, be very surprised if it didn't vibrate & lasted! But man super impressive!
Its a shame how he welds though. Hes a good welder. If he didnt do it downhill, or that horrendously wide weave, hed have my utmost respect.
Exactly my thoughts, how do you keep it balanced and straight.
no eye glass, no gloves, no protection from flying metal flakes... this guy welds a crankshaft while smoking a cigarette... respect.
It's not respect. It's stupidity. I am sure he knows the dangers.
Great skills however.
Who needs protective gear when you have tough skin 🥴

@@RayRay-rk5bd why do you think we have two eyes for, see 😳🤭
No gloves is a good thing. Wearing gloves while using a lathe is asking for trouble.
No glasses is obviously wrong.
This guy deserves all my respect for his dexterity and his welding skills. I don't know what type of welding rod he uses, but it seems a good one also.
This man has developed exceptional skills. This takes application good learning practices and minimising errors. Proof of his abilities rests as much on the fact he still has all his fingers and both eyes as it is in the finished product.
You dont have a clue about that kind of job right?I can see it from what you write here.
@@giotispaok2167 I came to say the same thing, and apparently there are 14 other totally ignorant others who agree with him....smh
This is a total hack job first off he measured the width of that main bearing with a scale, so much for the thrust bearings. He made this out of two old different old crank shafts, so it is no longer balanced, and sure just grab a 7018 and weld that thing, no preheat just burn it in good 🤣
You're a good observer and summed it up elegantly. Indeed, he is good and these are the people who the earth would need more than ever. Imagine all the unnecessary energy wastage a modern way of thinking would result in by melting everything down and re-machine it on a CNC. Most men today couldn't imagine doing this with a lot less energy but with a lot more dexterity though. I guess this is why engineering is still a man's job, eh?
@@integr8er66 That kind of jobs needs extreme precision.So i agree with you all the way my friend.
I watch a lot of these guys fix and make things I Pakistan. This guy is by FAR the cleanest, accurate, and conscientious machinist yet. Makes the very best of what he has. His work is his HONOR!
It's a shame this level of documentation doesn't exist for the repairs done in America during the depression and during WWII. I look at it with amazement but my grandfather would have looked at it as a great way to save some money.
There are tons of videos documenting how to do this, that was produced by those same people for the war department at the time. Look up Periscope Films, lots of great stuff on there man!
That was an absolute pleasure to watch, true professional.
It's amazing what gets repaired when labor is cheap.
Absolutely crazy skills!! The fact that he has so little and is able to accomplish so much. He doesn’t waste anything he uses his welding rod box’s to keep his tool post slide covered and also a heat shield for his right foot while welding. He deserves to be the head guy at haus engineering. WOW. Unbelievable
I noticed the foot shield made of cardboard and thought the same thing, nothing gets wasted. He's an artist and this is real art.
Some things that I noticed besides the fact that it’s impressive to see it done
Notice the bag over his foot so the hot sparks aren’t landing on his bare foot ?
And when somebody yells
( I think it was a kid) he looked in that direction and never stopped welding !
That’s a guy that is skilled and confident in what he is doing
Just keeping all ten fingers in that shop is amazing considering how many hours it took him to become such a craftsman.
not everyone is a stupid idiot.. lol
I was thinking the same thing. No PPE at all.
The guys welding is better than most I've seen on you tube. His skills as a fabricator would pay him well in my Country 👍
Sadly, people like him wouldn't be able to learn and work such jobs in better paying countries since there a crankshaft won't be needing such repairs.
@@killerdinamo08 sadly 85% of the comments on this video are from people who are clueless and praise this shit work to thease unbalanced, warped, unevenly tempered, temporary crankshafts. I can weld for $10 an hour shit will end up like this guy but this is why I'm paid $28 an hour minimum
@@codeack101wlck they have done this kind of repairing service for years in this country, if its dosnt work than this kind of service will not exist any more.
when you dont have something but needs something some one will always improvise, adapt, and over come....this man shows the simple fact that most any thing can be done
Loved how he timed the journals. Much respect for these guy's talents
I agree. Fun to watch. I ran a lathe in a shop much like this one in northern mexico. Some of the guys lacked shoes, I spoke no spanish, my boss brought in the work and i did it any way I wanted. Hot as hell but at the same time, It was kind of cool.
i wondered that... not many spoke of it. like a comparitor .. simple and probably within a couple thousands.. mad skills

This is the guy youll be wanting to fix your crank if it broke....
Hi, will the crankshaft burst in this place??
@@RafaelTatarin There no such thing as fixing a broken crankshaft, you cant weld on a bit of metal and expect it to be as structurally sound as the other parts on the shaft. Mechanics don;t fix these for obvious reasons. 1 being mechanics arn't welders or metal workers. And even metal workers wouldnt fix this because it's never going to be the same. I give the guys credit for trying, they have a go. It's just not worth the risk of. Then it breaks of and bits of metal go through the manifold probly end up in the exhaust somewhere.
@@barristanselmy2758 Absolutely, some things cannot be repaired, they need to be replaced. If this crankshaft snaps again and destroys the engine, he will be spending 5x the price of a new crankshaft for rebuilding the complete engine.
@@jazko Just a waste of time really. Hope they learn about structural properties of steel soon before a whole family gets wiped out.
Not including the North American labor cost of breaking a motor down and doing all this work it would be cheaper in the long run just to replace it then it breaking down again and have to pay to retire this motor down again.

my dad did this before with simple tools during the late 70's, the customer want it fast (don't ever ask for that). The weld was absolutely beautiful and very little grinding, sanding and buffing because of his masterful skill. He told the truck owner to get a new one soon or avoid pushing too hard with lighter load, don't climb above certain height above sea level, because even the best weld is not a guarantee. Oh, boy that guy didn't listen. He overloaded his truck (way beyond overloaded), and went straight up the most steep hilly climb immediately with a super heavy foot on the gas(diesel). Two days later, they called on top of the mountain. The crank split, broke the block, destroyed a few piston rods, and the bottom of engine blown to pieces.
So true! Telling the customer to take it easy is like telling a bear not to eat a cake on a picnic table.
This guy is truly gifted. Old school machinists and welders knew how to do the impossible.
Это 100% профессионал,на коленке сделал. Илон Маск нервно курит в сторонке.

this looks like two different cranks welded together to form a single good one. i didn't see a plug used at the breaking point. much respect for the tech and a complicated job made to look easy. it only took ten cigarettes.
Lol
This guy sure knows how to lay down a bead. Pretty darn good machining skills too, especially considering what he has to work with. This is the first of these mid-east machine shop vids I've watched so far that actually shows the guy putting oil on the lathe ways. I think the first one where I've seen one of these fellows use a micrometer, too.
I've been an all position certified welder since the mid 80s and have been a machinist on manual machines for over 30 years, (I'm an older guy). I say the man in this vid did great for what he had. I wish he had a journal grinder. I'll bet he does too!
Would be interesting to know how many miles they get out of that crank. They didn't have a way to check the balance on it... Respect to the "dude", though!
he is craftsman indeed. with basic machines he can revive a dead crankshaft back to life like a frankenstein. it is really interesting how long it will last.

Incredible job, back before the generations of Sallies, we use to do this kind of old school stuff, now we buy new, due to safety.
That's just someone blowing smoke up your ass. It has nothing to do with safety, it's entirely about profit margins and cost/benefit. It's far less expensive to have a new one made by child slaves in a China factory than it is to maintain a machine shop.
generation of sallies ☻ Dude, you just snapped a picture of what I was thinking.
@@Anubis78250 Safety priced America out of industry, as new CNC equipment because available, so did new safety regulations through OSHA. Eventually it just became a money grab for the suits.
Safety is a good thing, until they weaponized it for control.
That is good workmanship, from start to finish all by one worker! Won't see that just anywhere.
To all those who are saying this won't work the crank will only last a few miles, you're talking rubbish. Is this job perfect? No; but were these cranks perfect when they came from the factory? No. These aren't racing engines, I doubt they were carefully dynamically balanced when they left the factory? This must be quite an expensive repair even in Pakistan, by the standards of Pakistan this bloke must be well paid with these skills, he can use measuring tools, he can turn and weld. Look at the number of cranks they are repairing, if they only lasted a few tens of miles they wouldn't be a business reconditioning these cranks for long. Would it be better if the cranks were reground? Yes; but is what they are doing good enough? Clearly yes.
But I would like to know why are the cranks failing where they are failing? That seems odd to me.
Thanks for watching 😊
@Henry J. I was wondering if it might be the overuse of engine braking due to brakes fading on overloaded vehicles on steep inclines?
As someone who has built multiple engines I can guarantee that all crankshafts (at least in the western world) come out of the factory balanced. Where he welded will guarantee a future point of failure because the grain structure of metal has been completely altered. This is only done in 3rd world countries because they have no other option. Where buying a new crankshaft would take a month's worth of profit.
@@Halmengineer There are plenty of engines with cast iron cranks, he seemed to be using non-standard high carbon steel welding rods, my guess is this repair works. Even in the West rare cranks have metal spray repair to crankpins. Yes cranks have to be balanced, but we are looking at a comparatively low revving engine. Is the repair perfect no but I bet it lasts thousands of miles.
@@Halmengineer I'm not going to disagree, but it could be that the balance is expected to be done with the rest of the rotating assembly. Odds are the old rods and pistons are destroyed. Also, i'm just some random guy on youtube, but welding should be fine on a cast steel crank.
This man is clearly an expert in his craft! OMG what a lot of work!

Thanks for your love and appreciation
I watched an old timer weld a cylinder wall with a torch and coat hanger. He cleaned it up, honed it out and put back in his wrecker. His son still has the wrecker and it still runs like a champ. That was over 30 years ago. How time fly’s.
Interesting - coat hanger steel is fairly hard yet not brittle. I wonder what are the metallurgy specs of it.
the nicest looking weld in the word on cast wont hold. you can see he tried to weld it before. The power of that piston combustion stoke will break the weld. .IT is cast and you cant weld cast for strength. only for looks.
So you’re saying they fixed all the 100 shafts you see in the shop just for fun, and they’ve never done this before?
@@MR-cp4sj Can you read? Do you see where I said " you can see he tried to weld it before" ? Because in this video he is fixing it exactly where he welded it that same way in the exact same spot before , Or cant you see that? can't you see how the metal broke off, and it looked like worm a gear. that break that way is because the weld cannot hold to cast uniformly. you dont see him chip off the old weld fragments with a hammer? Cast is porous. ANy weld is superficial and not for strength. Is is ok to use weld to retore a bearing surface, BUT TO make it HOLD and last he would need to make the ends he inserts into one another another into spline fittings. and he would need to cut the male and the receiver ends into spline grooves to accept each other and provide interface rotational strength to prevent the welds from breaking. The weld alone will not hold. Cantilever force is to great for a weld alone to hold it. ALL those cranks were fixed before. In the same spot over and over. If you cant see that on the one he does in this video, then you should not be watching these type videos. you should be watching only things you know what the hell you are looking at.
Amazing skills without special tools. That’s a real working man! 👍👍
up to 26:00 I was wondering, how they would fix welding deformations... yeaaaaaah... just bend it back with a hydraulic press :)
Sleeving the 2 pieces is the way it's done the hole for indexing the 2 parts ensures he has a proper index when the 2 pieces slide back in Great job sir from a fello metal worker.

when I was a kid, applying for a job at a machine shop that handled farm equipment, the deciding question was, "Can you weld crankshafts" I never got hired. He is using old equipment, too- amazing video
Obviously, a broken crankshaft is a result of a tremendous engine failure, and I've never heard of someone actually repairing crankshafts, particularly broken crankshafts as this one was. For sure this gentleman is highly skilled at his trade. I also took note of how clean he keeps his work areas, namely the lathe and the fact there are not huge piles of metal shavings all about. While I'm not a machinest, nor a welder, I certainly noticed he lapped some most excellent beads as well to build up that journal bearing. Very impressed!

Может немного походит .
I worked 22 yrs for Cummins Engine making large crankshafts, gearing, camshafts, valves, capscrew head bolts and piston pins --- In our lab we discovered welded together crankshafts returning back to us broken. A chop shop up North was welding these cranks together, then chrome them and grind back down to size. These welded cranks couldn't withstand the torque commonly realized in the average semi. These chop shows were coming to our town and buying up from the scrap dealer cranks we scrapped out for one reason or another. When the cranks would break under the torque and blow out the side of the engine they'd come to Cummins filing a warranty claim to replace their engine. When we discovered all these returns were previously scrapped out cranks, FBI then got involved since the purchased scrap cranks were transported across state lines. Well, that "criminal" ended up getting a large fine and 25 years in prison for his "efforts" !
If this is true, I don’t understand why that person would get that much prison time, if any? What law was being broken here? Those customers paid for a product that ended up not being that great. That’s the risk of the customer, not that shop. Did the engine blow up and then a semi ran into and killed a family or something? I think manufacturers bare the responsibly of that, but you don’t see managers at Ford going to prison for something like this.
You get 25 years in prison for murder... Not for violating a warranty policy.
@@dooby1445 Scrap has to be scrapped, not resold as new. He was defrauding his customers and putting the public at risk by having semis on the highway with faulty parts that would lead to accidents and possibly deaths.
Very odd. It broke at the front of the crankshaft, the part with the least torque on it. Plus it also looks like it has been drilled out and welded there before. One might suspect that the engine had a very bad harmonic balancer on the front and that imbalance eventually, and then again, snapped the crank. Now the large center drilling area is not welded so it's not going to transfer any torque, so the crank is going to be even weaker than before. Doing the same things a second time is just going to result in a third break.
The crank is hardended steel so whatever welding you did undid the hardening process and itll need to be surface hardened again
It's India. They don't give a feck about stuff like that!
@@Malc2169 it's Pakistan
@@adelaseeri768 India - Pakistan - Southeast Asia... trying to tell me standards in India are any better than Pakistan or the rest of the region?
OK. These pieces are parts of TWO different crankshafts of the same type. Look at the pictures. The short piece is broken end of one crank. The larger portion has the counterweight cut off with a torch. This provides the guy with enough extra material to do the job. And, yes the guy has great welding skills. Aligning the two pieces and straightening the finished crank.
I must have missed something because he cut a big chunk out of that shaft and I didn't see him add anything back. I'm not sure how it didn't get shorter.
And what's the deal with theses guys welding shields never having head gear? It wouldn't be hard to make.
Yeah I was wondering the same thing. My guess is he matched broken parts from two different crankshafts, and had extra steel to work with.
He used a bit off another broken crankshaft
The next video he cuts and shortens the block at that bearing location the exact length the crank was shortened!😉
Cant believe these guys rock lathes the way they do with long sleeve shirts on!
Hope they checked or drilled out the angled oil hole to the main bearing or all that work is for nought.
I was thinking the same thing
Did this guy come in on a Sunday? Usually, I see guys laying around or just sitting and on their cell phones, watching workers like this. He’s really good at what he does. I would’ve tried and been run out while the owner would have to buy a new crankshaft for the customer.

Wow You guys are amazing can we please send our kids over there from America so they can learn how to do something other than play on their phones !!!
the last one who drilled the hole could have at least had the respect and could have cleaned the crankshaft....:-(
Wow! I felt sorry for his arm when he polished the crankpins :) But it all was so soothing to watch, work well done! :P

Ten bonus points for smoking a tab whilst on the lathe, five bonus points for not losing a finger on the webs.
👍👍👍👍👍👋.
I can readily see the interference fit of the two pieces however how is the overall original LENGTH maintained? With the longer unit clearly torch cut, this appears to be two identical crankshafts spliced together, not one joined back together? Also, I guess there is no way to repair the rod journals, only main journals?
Why wouldn't there be? The shaft would be unbalanced on the lathe, but I don't think that makes the job impossible.
Rod journals can be done as well, it's just a little more tricky to set up in the lathe.. the length and concentricity is controlled by the spigot he machined before welding
I think part of the process was skipped. What looks like a torch cut may have actually been the result of welding a rod into the long piece. Boring it to receive the rod then welding it
Making one crank from two would throw the balance off. Not to say they couldn't re-balance at the end.
@@tagert1975 nah it was definitely 2 cranks made into 1.. if they were going to just dowel 1 crank back together it wouldn't achieve anything to weld only one side in and that was definitely torch cut
He could have welded on more material to an end before starting here and torched it flush
amazing skills...I loved how he kept glancing toward the street to check out the traffic or people walking by.
Maybe he was on the lookout for a Health and Safety Inspectorate guy...
Привод у токарного интересный. Коробки нет, ломаться нечему.

И ремень вроде перекидывать можно
Ременный перебор . Ломаться может и нечему , а силовую нагрузку не выдержит . Так , чисто для ремонтных работ .

Superb. I'm really impressed by this man's skill. What a talent.
Excelente profissional, serviço perfeito !!!! 👏👏👏👏👏
Just show you can do anything if you have to. These guys are fantastic
Токарь 95LVL он может точить деталь на токарном станке, в это время курить, варить ручной дуговой сваркой. Ему не нужны средства защиты.
As a tool maker i could criticize this work but looking at the tools and machines he had available its exceptional work... the weld was amazing. not even a microscopic bit of pitting...

That's some serious shit. Amazing skill, keep it coming.
This dude is very talented and well rounded
You can weld it and machine it smooth again, but it will never be as strong as the original forging. I've done similar work on less critical parts.
The grain direction will be randomized in the area that was heated and lose strength accordingly. Billet steel has a grain just as wood does, and like wood it is strongest across the grain and weakest parallel with it.
There's good reason for forging steel parts like crankshafts in a single piece rather than just cast them to shape, and it's not just to provide a rough shape to machine to size. This video seems like it explains it pretty well. ruclips.net/video/-cFJMNyTxGU/видео.html
Yeah but looking at where they are at probably where they live I do not think they can just get these crank shafts whenever they want hence why they are repairing rather than replacing. It'll never be as strong as it used to but for the needs of the area probably more than strong enough to suit the task for long enough.
@@coll6 A basic car, maybe. If it's for a truck that works hard then it will not last. But as you stated sometimes you do what you can with what ya got.
Could also very well not be forged. Cast cranks aren’t super strong to begin with yet still last the full lifespan of engines they were designed to be in. I think this repair will last.
@@ryanflaherty3153 I was just about to say the same thing lol, im sure that crank was cast and they know what it is theyre getting into
The original crank broke so it's a mute point. The life span, heat, loads and backlash on that crank were probably huge! He cut back from the fractured zone and welded in materials stronger than the crank. We'll never know if it breaks again but I don't think he'd be in a job with so much skill if it didn't workout.
From Canada 👍👍👍 Absolutely Fantastic.
I don't understand how you can take 2 pieces of a broken crankshaft and cut one end to fit into the other and not end up with a shorter crankshaft. What am I missing here?
The 2 pieces are not from the same crankshaft, you see it in the first scene. I think they made one out off two.
Ohh isn't the same piece it take 2 for craft 1
@@nachwende-ossi9563 ahhh I see... thanks I missed that too.
I worked for a metal stamping shop with large punch presses. A few times the crankshafts would break and a company would come and repair the in the same manner. The crankshafts probably weighed 2-3 thousand pounds.
