We need to see the follow-on video "first startup"
Its nice work.. but for entertainment only this old crackshaft was not in use (rusted) and obviously cut with a cutting torch.😂
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
@@RJ-lj3zt well aware of that. In the old days this was all we had to work with. Folks are spoiled now.
*I love the way he eyeballed the proper angular relationships for the throws on one half of the crank to the other half, did everything with a cheap caliper, maintained perfect axial linearity along the entire length of the crankshaft, and thinks that weld is going to be anywhere near as strong as that massive section where it broke. I also wonder if he forgot about the oil gallery. This was entertaining to watch, but I don't think that shaft ever did anymore cranking. He might as well have used J.B. Weld, but that wouldn't have been as interesting.* 😁
You are forgetting the iterferance fit where he hammered the sections together
@@marcos3ltrv6I forgot the precision pocket tape measure too...
Imagine that crank in an engine, in an overloaded 10 wheel cargo truck, roaring up a Pakistani switchback mountain road, at full throttle in low...and then hit a big pothole or other road obstacle, lurch backward, pop the clutch, try to shift into low low, grind the gears, herkyjerk forward...etc.
Those forces are why crankshafts are forged in 1, big, beefy piece.
And the fact that the weld is extremely brittle compared to the virgin material. I agree with everyone here. If anyone here has ever welded before, you know that normally the weld wont break, but it will break right next to where it was welded since the weld is alot stronger that the virgin metal. And, adding all that heat did nt help it either since the entire thing wasn t heated to the same temperature.
The first time that I have ever watched the production of an engine block "Hogger" with a Wankshaft !!............................
*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.
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
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.
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!
Даже не думал, что такую поломку коленвала можно сделать, однако факт на лицо, перед профессионализмом мастеров снимаю шляпу, молодцы!
I held my breath when he was holding that rag to wipe the journals down while it was still running.
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
Мне очень интересно машина с таким двигателем . Хоть заведется или доезжает до соседнего гаража и начинается все по новой
All this work and no carbide inserts. Just hand ground cemented carbide and high speed steel. Amazing!
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.
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'm sorry that I don't know your language at all. But I'm sure your comment says good things.@@Murman55
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!!
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 TH-cam 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?
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
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.
@@poopy_pants_joe1194 It's the torque that would rip it apart again, but I don't think he really planned to use this for anything beyond making the video.
@@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
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 TH-cam 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.
@@polygamous1 It probably wouldn't even spin once he torqued the bearing caps down.
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.
Ich kann mir nicht vorstellen, dass der Rundlauf im Dreibackenfutter auch nur annähernd genau genau genug ist.
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.
Wow, these guys do not waste anything in their shop, amazing workmanship on display.
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
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.
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.
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.
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!
Tool above centre, no dial indicator and no auto feed. That is the roughest machining I ever saw. The crank shaft was a piece of rusty scrap metal before he even started. Did he not see the journals rusted and pitted. I wonder what the tolerance was? Plus or minus a quarter inch. Incredible work considering the time taken and the situation. It must have been out of a diesel cause I didn`t see him worry about any timing or top dead centres.
Ah come on mate, those rusted journal pits hold more oil to keep the bearings in good order.
And don't forget, it's India, make do.
Indian genius at work ! ! !👍👍👍
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 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.
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.
After wrenching for over 50 years, I love watching these guys. But the odds of the repair lasting long-term is doubtful.
After installation, the vehicle will need to be babied. I'd worry about oil to the journals too. That was not addressed.
Or sold
turn it into a gas engine to lessen forces ...
@@orangestoneface Yeah...even sounds easy.
@@CONTACTLIGHTTOMMY and use the engine to run a generator or pump water for low shock forces
@@orangestoneface Yeah...I was going to say the same thing. Applications that are constant and without sudden shock loads.
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?
Chances of this crank being clocked perfect and journas being straight and true is zero. No pre or post heat treatment either, so expect it will fail again. That being said when you see how they do engine overhauls, it probably doesn't matter much, it just has to run.
Have to give these guys credit though, they do the kind of repairs that most wouldn't even try. They make do with what they have to work with. Used parts are plenty and new ones are too expensive and likely not easy to get.
Both halves of the crankshaft look like they were torchcut….. was this from two different engines? Also, why use an old gear to machine down as a main journal…. Convenient material? Machining a wider v would have allowed deeper weld penetration. I’m sure the mains would have required regrinding to assure concentricity. Nice repair but questionable
Deliberately torch-cut. Crankshaft will not survive long following repair. The welding has changed the molecular structure of the metal. Don't try this method of repair.
Torch cut and the journals are blued, so it's already compromised
Nice boat anchor

The polishing rag process got me cringing.

"brave" isn't doing something stupid and surviving... in fact, it feels like nature fucked up doing its job weeding out the defective genes.
Unbelievable and amazing
Just amazing
Gotta love the safety sandals!
Open toed safety sandals are the best! 😉
Amazing how no coolant was used when machining ! Mind you, looking at the other journals, it’s doubtful if the crankshaft would be worth all the effort without proper grinding (with coolant). I am astonished that he was able to machine the gear as normally they are case hardened!! However, thumbs up for an entertaining TH-cam video, despite the safety issues.
Good to see he was wearing his safety flip flops!!!
Most crank gears are not very hard. They run with a alloy or fibre cam gear. Though normally you simply press or pull them off.
@@garethblake544 Flip Flops von Engelbert Strauss!😂
The gear was probably cast/machined in a similar shop in PK, so it wasn't all that hard.
Superb
Doing such a precision job with a tape measure and wire hanger is insane
Very nice beautiful good job 👍
I see absolutely nothing that could possibly go wrong here. Nope, that crankshaft hasn't already broken in precisely the same spot and shoddily welded several times before. Nope, that didn't happen. And no, the next crank journal hasn't turned blue from being overheated either. Nope nope nope. Everything is golden.
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.
there is no way that crank will ever work again. just getting in straight and the exact length would be a feat into itself but also the angularity of the crank pins is critical
Race ready! Dude could definitely do work for Roadkill Garage.

This is Devils magic!! haha , when you tweak a CS, its done but this! I guess if you weld it properly and balance and true it and its supported in the engine correctly then this repair will last forever?
Thought going to the moon was difficult but this?
This is a TH-cam special , just made for content. It's not going into an engine, ever. The fact that so many people think this is an actual repair is hilarious. There are countless reasons why this crank would never function again.
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
Eyeing up the journal timing...............now I've seen everything!!!
Personally, I would have heated up the parts for a fit, rather than swaged them in. This guy is a VERY competent Engineer.
Wow! Its like 3rd world magic, they oriented the journals of the two parts by eye (sorta), beat them together with a sledge and then tacked them over naked ways... which apparently never needs oil of any kind, ever. Just sayin, if that crank doesn't hang a rod out the side of the block its gonna be genuine MIRACLE!
Now to be honest, I TOTALLY could see doing this myself, after about a case of beer and as a joke, but, even then, I'd wear proper shoes and eye protection. As a joke, its STUPID funny, but done seriously... for money?! its gross negligence!
To really appreciate the insanity of this "repair", that crank is going to be operating heavy equipment, spinning at 3,000 RPM, transferring 400HP and about 3500FP of torque to the transmission... at that speed and torque, all the rod journals and main journals have to be in near perfect alignment 5/1000ths of an inch... the alignment of the rod journals have to be clocked to the same degree of precision... or the Crank will blow up.
When that crank blows up, and it will, it will take out the block, cams, rods and pistons, so this dirt cheap repair will essentially trash the entire motor making it unrepairable.
@@craftycri YOUR RIGHT...just glad I'm not going to be there when it blows. its not even balanced any more.
In their part of the world , precision is secondary to earning a living. If the motor can survive 10 more trips then the repair probably paid for itself and the owner can use the time to search for a better motor before it grenades !
@@olduhfguy Sure, guy... if they actually put that crank in a block, install pistons, rods, main and rod bearings, gaskets and rings, head gasket, heads, water, fuel and oil pumps, mount it in a truck, connect the exhaust, electrical and fuel lines... you're looking at roughly 40+ man-hours for 10 hrs motor run time, IF it doesn't hang a rod out the block on the first rotation.
The cost benefit of that exercise is off the charts stupid, and its no wonder their economy and culture is in the toilet.
I doubt they can even assemble the engine, let alone start it.

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👍🙏
I belive, that this crankshaft will breaks again. Acrankshaft is forged from one piece of steel and tempered to reduce the tension within the material structure. A weld seam creates tension in the material again when it cools down and also represents a weak point due to the different material. Not discussed the uncompensated unbalance that the shaft now has. Not a good idea to do something like that.
Good job my friend...🙏
Well, Garage54 proved that a welded crankshaft can hold together, but they used a different nethod for filling the missing material: it was practically 100% weld.
How did they set the timing on a crack through and I forgot to drill and oil port for the main bearing
Gotta love the safety sandals!. The polishing rag process got me cringing.A brave man indeed !.
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!
I think he was showing us the basic process of “repairing” a crankshaft, I don’t think this one was ever going to be used again
Very resourceful. Taking two pieces of worthless scrap metal and turning into a single piece of worthless scrap metal that made them some money from people watching them do it.
¡¡ESE ES UN MECANICO CON MAYUSCULAS !! 👏👏
And... you gotta love those highly protective welding helmets!!
Дайте им предприятие Илона Маска, они неделю будут затылок чесать, а на следующей в другую галактику улетят 😂😂😂 вот они какие молодцы 😅😅😅
I like the gentile way he placed the first half of the crankshaft on the floor after he finished matching it !!!!
Gentile way? Hmmmm….
Yeah, almost like putting a new born in a crib,lol
This is ingenious.👍👍.
Excelente tornero espectacular te felicito 👏 👍 😉
I really appreciate the ability of this machinist, if it will last is another matter. Great Job.
Is that a Starrett wire indicator? Nice work fellas.
$362, at harbour frieght..
If I were somehow entered in a cross Asia road rally, and the crankshaft in my sports car broke, I'd be more than happy for these guys to take a crack at it. I own a lathe, and a several welders, and this repair ain't half bad. I knew a guy who did welding at a nuclear power plant. When they joined, big, high pressure pipe they would do the deep "V" machining and then the repetitive concentric welding like that employed here. For some, it probably does not meet western high standards, but heck, they are probably hoping to get another season out of a tractor. I think they will get several more.
Just a bit rough but might be OK for low RM low stress high tolerance engine. Where is the oil outlet in the main bearing he just patched in? Could be they drilled that later?
How can centers meet up with hammer bangs like that, you machinists are totally amazing❤!!
one missed blow, there goes the hand for life..
Surreal ótimo trabalho!
😃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🤣🤣🤣🤣🤣
I hope he gets that extended car warranty.
I have done some very strange things to make something run again, part of a soda can under a bearing or file folders, even dumped some lead to get it thick enough to make it fit. I have welded and hand filed the front of a crank so the balancer had a place to live. But I just can't see how this would work for long, not counting if you did get it in and running, there are going to be horrible timing issues that can't be solved. But Kudos for trying, sure would luv to see the engine run with that crank in it, or at least the attempt.
The timing can not be done using just your eyes no way, These guys are good but not that good. And we have not talked about the taper it would have. It will be fun putting it in a block with bearing on it. But I could have never done this good.
А как она будет смазываться, эта шейка?
лоху продадут, а это его заботы, как будет смазываться
I like the eyeball register of the crank throws, how long will it last in use I wonder?
Wonderful.
Very nice
good job
Kudos for having a cement floor. It would be amazing to see how the drive shaft handles under a load. You use what you have though, right? ☕😀
Great work, good workers, bad job. Slag inclusions in the welds, sub surface discontinuities and they didn’t drill out oil holes. I wouldn’t trust it to get me out of the parking lot.
Excelente trabalho parabéns
MAN... I just love their style of steel toe safety shoes. I guess it's their version of OSHA. Wonder how many are missing one or more digits??
