Wow, did you see how good he was with that dial indicator? No? Me either.
Should be. "No? Me neither"
Providing it isn’t put back in the engine, the repair should be sufficient.
Safety sandals to the rescue
Lololol?
It keeps getting put back in the engine, and he keeps fixing it when it snaps in half
That was my exact thinking. No measurements or references other than the ol' M-1 Eyeball. He could have at least had the motor close by. Sheeese. What gives with the "guess and by golly" method?
Люди в тапках способны на всё.
My question is, is it worth the effort? What about buying a replacement part?
I would watch my toes!!!!

30 seconds of vibration 2 seconds of boom
Plus the heat-treated surfaces ruined and finally the surface finish on the "bearing surfaces" was abysmal to say the least.

I'd give it a go. It's for a slow revving Lister engine, not a high revving Hemi.
There's no way that's ever gonna go back in an engine and it'll run properly. There's a good reason that engine parts are cast/machined in high-tech facilities to very tight tolerances, have heat treatment, are balanced and have ground bearing surfaces etc.

И так сойдёт ))
Смотреть интересно, но работать долго не будет
Incredible! They took a broken crank and made it an out of round crank with a junk journal!
Couldn’t agree more!!!
That bearing journal had to be at least 10 to 15 thousands out of round!! And using that grinder to polish the bearing journals OMG!!! good luck getting bearings to fit not that it would last long even if they did find them. That was an atrocious repair attempt!!!
How to make a great canoe anchor!!
lol. 😂
Hilarious
And the poor fitter has to get the mushroomn off the end of the thread
It was probably used for a steam engine max speed 80 rpm
That crank should last a long time, like another 25 hours or so.
25 minutes would be optimistic I reckon.
Самый прикол, что та ерня будет работать.
It comes complete with a 30/30 warranty. 30 feet or 30 seconds, whichever comes first! 😂
You're too generous. The end goal is crankcase ventilation to re-harden the crankshaft. 😂
25 hrs and then when they put it into the engine 25 seconds until the engine fires up and booom.
Похоже колено от какого-то древнего одноцилиндрового дизеля, который крутит водяную помпу или что-то подобное и запчасти на который уже не достать - другого обьяснения этому "занятию" нет. Вставку делают хрен пойми из чего и отработает это недолго от слова совсем, лопнет повторно - блок размолотит! А шлифовка болгаркой это просто нечто!!!Сопромат вещь упрямая и его не наеб... шь😂😂😂

You don't repair crankshaft journals with a grinder .
У них допуски 1,5 мм - сойдет😂
Necessity says that yes you can repair a crankshaft.
With a three jaw chuck? That end journal looked to have a good 20thou runout. I do admire his talent and tenacity though.
Vibration never hurt a crankshaft...👍
and the bearings, will they like it ? 😧
Incorrect statement
@@premprakashdubey2751the comment was sarcasm

Мне кажется в конце он сказал: "ещё походит".
20:25 там биение конкретное)) Это не ремонт, а контент на канал)))
По моему Пакистан....только они могут такое . Респект токарям
Скорее Индия , там обычно такие веселые ребята , хотя может и Пакистан . в Индии лично наблюдал таких же вот деятелей которые облманые полуоси на грузовике восстанавливали их хватило до первого причем не очень серьезного подъема . по прямой до этого километров 10 прошёл .

I could do this. But I wouldn't.
Даже так в сто раз лучше чем ни чего 👍
I bet those red hot chips didn't feel good in his sandals
Holding breath for at least 5 minutes eases the pain.
I’m going to say well done mate, I’m not sure what the crank is off but here’s hoping it’s a light load and not too many revs. Under the circumstances I can understand the need for a repair
It actually looks like a crank of an old single cylinder horizontal air compressor like a Worthington style. I give whatever it is about 4 minutes run time at anything over 50rpm.
No clocking, no lubricants. Great job...
A dial indicator and a 4 jaw chuck would have been nice, love to see it run, but excuse me if i hide behind a big tree or block of granite!
Just love the precision of the work here! Lol I’ll give it ten minutes lifespan if that.
I’m impressed at the amount of deflection in the drill bits as they recenter themselves upon contact. But hey, almost half a million views in two weeks, that bit of foolery made them a few bucks.
Это даже не клоунада,просто бестолковый цирк
Да это как раз и делается для просмотров шлак полнейший)))))
Особенно бессмысленный фокус с газовой горелкой. Басня Крылова "Мартышка и очки"
Залипуха полнейшая, шейка коленвала должна шлифоваться под размеры вкладышей, а тут болгаркой снял ржавчину, борозд понаделал, но оно и понятно, всё на коленках делается.
Ремонтный вкладыш поставить и на разок хватит спуститься с гор за солью в кишлак
@@rk1at436судя по всему вкладыши под этот коленвал в соседнем сарае какой-нибудь кузнец из старой алюминиевой кастрюли делает по индивидуальным размерам.
Сколько смотрю, всегда поражаюсь, техника безопасности на (высшем) уровне.
No this is totaly wrong, must use Super Glue before welding....
He didnt use the skyhook once either to insure alignment
Can we appreciate that he drove it across the road. After all, “time is money”😂😂
Why I didn't watch much.
Hammering the crap out of it in the lathe chuck.....
Since there's no quality control in the W/Shop , it shows there are a lot of mistakes, crankshaft concentercity is unacceptable, and usually, crankshaft shaft is hardened and by using torch for heating to soften the material for easy machining then crankshaft must be hardened back .
Maybe they hardened it back after this machining, I hope 😅
this is just some staged stuff to make a video its a money grab ! would like to see that crank in a running motor
Se a peça maciça quebrou.
Imagina essa com alguns milímetros de solda.
Even if it only lasts 30 minutes it’s still impressive what they can do with relatively low tech tools. I mean no I wouldn’t do it that way, definitely need to at least indicate the stuff in a re harden but I still find it somewhat impressive
It was a scraped crankshaft to make a video with,,, who in hell ever use it with all the rust on the rod journal with out turning it down
Its part of betting machine. They bet how long it will work. This is the best quality company, because its pure random.
I believe there is 1mm or more of misalignment, it will break again haha
Ya, not good workmanship Lot of whirling seen at far end of shaft ! Next time they will come up with Bearings ?? 😀
Не Боги горшки обжигают, а такие специалисты в своей технологичной области!
Cada rotação do virabrequim será uma troca de bronzina😂😂😂.
O serviço tava indo tão bem !
He is making an art piece leg for a table. 👍
I wouldn't trust that on anything but a yard ornament. Misaligned and short weld depths is an accident waiting to happen.
He just changed the molecular structure of that by heating it up that high its definitely gonna brake
Why else would he torch it before continuing to mill it? Must have been to ruin the temper so he could mill it more easily.
Perhaps they send it off for heat-treating and final milling after roughing it out in this workshop?
COOL PROCESS! but won't heating parts of that crank change the properties of the metal?
plus it was only heated on one side if it and how about balancing and the TDC won't be exact...
Well done❤
Love the safety shoes.
There is Saw, the killer of humans. And there is you, the killer of engines. Think about the soul of the driver
Все что наварил то срезал. Ура.
Very good,soon you will have your own space program
real precise work.
they already launch rockets and have exploded nuclear weapons while you are whining about this most fantastic use of a lathe, made in the Republic of China hahahahahhahahaa
A lot of run out on the bearing surface on repaired side.
Metallurgy left the room ..............,.....,...................engineering left the room
Вот бы еще посмотреть как двигатель работает после сборки на этом колене
the way he polished up those journals in the end .🤣😂 .
hahaha he measured the shaft length a bit like 'aaah this is about right' 1:22 ... holding the broken pieces 'a bit into place'
Total BS. You can see at 20:58 the crank journal next to the welding is clearly not running true. This thing is going to vibrate itself to pieces within minutes. I hope this guy didnt charge anything for this crap.
wtf. that crank is still junk. i love the hand grinding of the bearing journals. wow.
A skilled craftsman and his joy machine.🎉
You know nothing !!! It's a poor... shit. ... misaligned repair.
Думаю его токарный станок долго не протянет, если на нем вести сварочные работы 😮
Подшипники долго не протянут.
От сварочных ничего не будет, а вот от ушм пыль абразивная, но если сразу протереть станину, но не страшно.
@@filyamatross4100 окалина и есть абразив!
That crank is junk. Angle grinder on the main journal 🤣
سلمت يداك معلم ممتاز جدا جدا جدا ❤
Definitely polishing a turd... Wonder how long it lasted to create a ticking time bomb though.
I agree with most of the negative comments. I still find the proces fascinating to watch. Could a bad repair be their best option?
В 90-х занимался мотокроссом. Была у нас одна беда, клинил сипоратор шатуна на колене от нагрузки и оборотов. Он был с алюминиевой обоймой. Разбирали кувалдой колено, меняли на такой же, только с бронзовой обоймой, прессовали обратно кувалдой, на токарном станке с микрометром и с помощью кувалды равняли. В прицыпе всё ходило, обороты двигателя около +/- 8000. Но приходилось систему зажигания, якорь, переделывать, делать через виброкомпенсатор с резиновой проставкой. Но подшипники не разваливались, я думаю из-за того, что они не плохо держат продольную нагрузку, плохо поперечную.
Ну а видео, да, может это от парового движка)
NO ONE should EVER except the Re-hashed outcome of this job, it'll bust and potentially cause a serious incident!!!!!!!🤬👎
Come on! It’s genius. This is primitive stuff admittedly but where it might be impossible or too expensive to source a replacement, this is brilliant stuff.
@@AdrianShawDrummer- No. It’s an attempt to be a genius. The method used is actually pretty good in terms of the design. The implementation is not accurate enough. Far too little attention spent on run out, or the overall length. If done to the dimensions of a drawing - okay. The final crankshaft is not going to run true on its bearings, if it even runs at all. I still have doubts about the metallurgy - steel can be welded yes, but in doing so the localised heating and then cooling creates internal stress. Ideally a component welded this way needs heating and slowly cooling to relieve the heat stressing. Or cryotreatment with liquid nitrogen. Either way, no attempt to relieve welding stress has been done, the accuracy is suspect - job is therefore highly likely to break once again, if the crankshaft even fits the engine again.
I believe it’s accept, not except.. but I’m no mathematician.
😮😮🎉🎉@@AdrianShawDrummer
U r 100% right. The guy never put an indicator on the journals. He left a sharp corner where shaft joins crank. You can see the shaft running out .060” or so. Not in America!
All the journals are undersize the keyway is not indexed any longer. The connecting rod
radial runout is bad.
Who takes a grinder to crank journals?
Journals? They use diary.... clearly
Keyway? That was an industrial street...
Runout? They transported in with a motorcycle im sure the sent it out via motorcycle as well.
Grinder? Well most cranks are ground!
болгаркой под конец всё убил
НЕ, это он хонингование сделал.
Убил он сразу..когда начал варить... а потом не разрушающий контроль качества сварного шва на глазок сделал...
@@sergeuserdjio4023 да шов еще ладно, если нормальные электроды прочность будет, вот биение конское - это плохо. Надо было выставлять по подшипникам, да и вал целиком обваривать и заново там конус протачивать и резьбу нарезать. Хотя если места под подшипники он болгаркой зачищает то там мозга нет совсем.
MashaALLAH Zbr10 ustad 😍😍😍😍
Using an angle grinder to polish the journals yeah that crankshaft will last probably less than 5 minutes before it spins a bearing or wipes it out.
Quel massacre et perte de temps. Je me suis fait avoir. C'est une parodie de réparation juste pour faire des vues TH-cam.
دقیقا 😂😂😂
Bah tu sais, dans ces pays-là, ils se débrouillent comme ils peuvent. Il manque beaucoup de contrôles de concentricité et d'alignement mais ça reste une réparation acceptable pour eux avec les moyens dont ils disposent.
O nome disso chama-se ARTE.
Parabéns ao senhor profissional!
Vejam como o volante vai saltar como atleta olimpico 😂😂😂😂😂
It will fit beautifully with that wobble on the shaft all the other junk in a scrap yard.
Great job guys. Thank you for posting.

Butchery….
Should’ve “shit canned” that crank and bought a new one. You’ll forever be changing bearings until eventually the entire motor is good for nothing but a boat anchor or scrap.
Welding metal that is still attached to the chuck isn't a good idea - probably wreaking the lathe motor. Well, it looks like this is securing "work for life" because I bet it has to come back in to get "fixed" again.
Выглядит надёжно )
If ever there was a nead for a video on how not to repair a broken crank shaft, this one would be an absolute must.
Exactly. No measurements. No comparisons. No nothing but eyeballing. Good grief!

The crank was clearing cut, I bet this thing was cut on purpose just to make the video and the crank will never actually be used. So no reason to care if it needs heat treated again.
Bom trabalho torneiro.muito bom aqui é do Brasil.tambem sou torneiro.e essa profissão está em esticão

Well to be honest lister made a lot of engines. So an old lister 1.5 hp hit and miss engine might be fine with this.
I can only imagine what our machinist would be screaming if I would use a cutting torch, a grinder and a welder ( that had no visible ground clamp on the work piece which means the the ground was going through the tail stock) would be screaming
Now it is junk! ... but hey....like the "Star Wars" Jawa-Background-Talks during the brutal treatment of that once fine crank:...." Uhh-Tidi!"
