А прикиньте, этим монстрам полуавтомат дать?!?!? Да бля, для них, это 3Д принтер!!!
После праздников возьму валидол и покажу этот видос нашему токарю, если его кондратий хватит, тут же его и откачаю.
Только не показывай ему момент где это чудо центром гайку ибашит закручивая, а то и валидол не поможет,не откачаете ;))
minus all the negative comments on here ,my hat goes off to these dudes for making things work for what little tools and machinery they have !!!!!!
У меня такое ощущение, что как они штампуют этот тотал то и работает он также по времёни, пару недель. И снова нужно отдавать мастеру для починки?
Зато мужики всегда при деле!)
Как и асфальт после первого дождя
Мои соболезнования покупателю этой детали😢
Это заказчику
есть такая категория ремонта; и цена у неё меньше. Заказчик знает когда менять на новые - значит не пришло ещё время. я сам работал в подобной шарашке в России; и что мы только не ремонтировали, варианты были вообще немыслимые - лишь поэтому и смотрю этот канал частенько
Они уже давно под санкциями. Новые запчасти или очень дорогие, или вообще не достать. Они таким образом летающие тарелки ремонтируют на заднем дворе.
@@user-ek8el5jp2c А не мыслимые ли они в это время еще вопрос)
@@Wwladislaw
ето то что ждёт Россию
Весту с помощью болгарки и електродов будут собирать
Кружки вместо поршней
😂😂😂😂
ШЛИЦЫ БОЛГАРКОЙ Я ЕЩЁ НЕ ВИДЕЛ КАК ДЕЛАЮТ! 😁😁😁
Воч ю сей нигга эври бади фак ю?
Жесть конечно......сразу думал, как они будут нарезать то, что наварили. Но когда увидел просто болгаркой без размеров - прифигел!
А я знал что болгарить будут. Родственник у меня венцы тепловозные так делает, причём много лет. Венцы маховиков тепловозных ДВС. Что удивительно ходят по несколько лет
технология нарезания зубьев вручную имеет место. Например все направляющие станков вообще притирают вручную. Хотя можно было бы на фрезерном станке сделать.
@@user-by9ue4ml9c так там какая металлоёмкрсть и размеры, а обороты???
Жалко не показали как они её обратно выдергивали:)
it jamed !! :D
Есть какая то недосказанность в этом кинополотне. Финал картины неодназначен. Главный герой оказался на жизненном перепутье. Дуализм конечного эпизода засталяет зрителя задуматься и переосмыслить свои жизненные приоритеты. Варить ли срезанные зубья судьбы кривыми электродами, споследующей обработкой душевным токарем. Либо выбрать стезю потребителя джанк ярдов, и заказать финал драйв с разборки бульдозеров на Алабамщине? Все не так однозначно. Заставляет зрителя сделать в будущем нелегкий выбор. Достоевщина в чистом виде.
У них не получилось, потому что какой-то хернёй начпли мерять. Надо было рулеткой, от начала и до конца, тогда бы всё влезло :)))
My old shop teacher called this "beat to fit, paint to match "machining .However; when you are as poor as these fellows are, you have to make do with what you have .The gear cutting/ hobbing cutters and mill and shapers required for the proper restoration of these splines is beyond their financial resources .I admire them for doing the repair without what the rest of the world calls proper technique.
пошла эта деталь на металлолом. звезду натянули, и дальше она ни туда ни сюда. А гигантского пресса, чтобы её хоть куда-нибудь сдвинуть, что-то я у них не наблюдаю. Видео внезапно прекратилось. На этом наши полномочия всё, называется.
Чем он натирал резьбу, когда нарезал, мелом чтоль?
Да ща он сходит за вращающимся центром и забьёт им звезду. Гайку на резьбу же получилось им посадить
Первый раз увидел сварщика в ботинках! И в конце ещё одного!!! Не в шлепанцах! 🤔
Они оба наказаны. Брак гонят на линию.
Святые шлёпанцы 😂
All these guys capping on these boys, WTH ? They are making do with what they have, that’s called adapting and overcoming the obstacles in front of you, something that Americans used to be good at. Now we’re so spoiled that we can’t even appreciate the fact that they are working their asses off, in the dirt, no less, moving all the pieces by hand, to make it happen. Also, the guys criticizing probably don’t show up to work half the time anyway. You boys got yourselves another subscriber, hat’s off to you for a great video, and a job well done! 🙏💪🤘🤘
I watch some of these vids and half the entertainment is seeing all the seething in the comments from pampered little boys that can't do anything without a heated garage and 30K in tools.
@@kscod6108 I heard that buddy, adapting and overcoming used to be American ideals, now like you said, most of them have super nice shops with all the tools and yet produce jack shit! I appreciate a hard work ethic no matter who it is! 💪💪🙏🙌🙌
Когда увидел в руках болгарку я понял -это конец сей басни закономерный , какие еще размеры вы о чем?
Send this to Kurtis from CEE, it'll send him to the madhouse!
YES
Send one to Warren at western truck and tractor repair too.
C and C Equipment and Squatch would get a kick out of it, too.
As someone who is from Peoria, this is painful to see.
Don’t forget Abom
Not forgetting Pacific Northwest hillbilly and watch Wes work
These are great videos. They show the rest of the world how NOT to make a proper repair...
So true
even a jew would cringe
I can see you in their situation doing nothing and starving to death
That part would probably cost $20k in America and I’ll bet the part is running in a D8 right now so I’d say well done. Necessity is the mother of invention
@@sjb3460 i don’t expect that the value of the dozer would justify a new part. If it were a nearly new machine I’d agree with you, but they are probably trying to squeeze the last few thousand hours out of the old lady. It was this, a secondhand part or nothing.
У меня 2 вопроса : 1 - зачем он меряет скобой когда у него есть Штангенциркуль? 2 - нафига поверх масла затирать каким то мелом? это какой то ритуал?
скобой точнее мерить. Это скорее всего не мел, а мыло.
Awesome video and hardworking people.
when i saw the grinder cutting by hand , then the sprocket teeth on the concrete block gouging , i knew a big sledge would be used, they should only fix wheel barrows .
you forgot the case hardening of the gears, or lack of i should say. this should last about 12 minutes.
just because you can doesn't mean you should
I saw the hammer coming from a mile off myself. When it arrived on the scene it was a doozie too. Must have been the biggest hammer in the village, I'm telling ya.
@@1pcfred Way to funny, i fear for their feet, that mother is a toe breaker for sure.
You think he got the pitch right on those gear teeth?😂
@@maxpuppy96 I don' think any of them could answer that.
I've already seen a lot of botch on this channel, but this one the top. The carving of the spline is the icing of the cake. Maybe the lathe operator should try them self as a sculptor.
на пол часа хотя бы хватит такого ремонта или до первого запуска /?
Не хуже новой будет 👍
@@sasha_creativity даже внешне не будет похоже на новое, не говоря уже про твердость металла
Да нормально он все сделал . Дайте его номер у кого есть , хочу гидроблок на коробке автомат восстановить
I'm sorry to say that somewhere during this entire process the patient died
))) надолго ли этот "ремонт"? мои сочувствия заказчику. How long will this "repair" last? my condolences to the customer
All our work has a 100% concrete guarantee....Once it's off our concrete, there goes 100% of your guarantee.
Пару часов может и поработает. Металл из закалённого превратился в сыромятину, отпустили его сваркой
Да и не в одной закалке дело! После болгарки ни о какой параллельности в шлицах и речи быть не может!!! А значит и контакт их будет точечным и быстренько всё сломает к херам собачьим...
Такой пипец в 90х выпускали УАЗ, шлицы на заднем и переднем карданах вырабатывались быстро..Как то приятель купил \новый\ кардан на барахолке и позвал меня (в принципе я напросился, так как возникли подозрения на счёт его покупки)дать оценку его приобретению для своего УАЗ 469. Я по обойме понял(несколько покоцана и будто прожила долгую жизнь), что сейчас будет ужас - быстро раскрутил и мы увидели какие то войлочные вставки в продольных шлицах(это чтобы не стучало в соединении при вертикальных нагрузках при помощи рук). Как приятель матерился, я опущу, он потом нашёл действительно новый, перебрав таким макаром кучу карданов. Я его немного раскритиковал, но что есть, то есть - советского выпуска конца 70х - начала 80х не найдёшь сразу).
@@Terramorfios ничего не изменилось, карданы и сейчас уаз делает из пластилина. Мы их называем неделька
Не знаю что и сказать, нет слов. Как у токаря, фрезеровщика одни недоумения. Клиентам, таких спецов обходите стороной.
А там других и нет скорее всего. Это верх доступных им технологий и спецов для широкого применения. Страна под санкциями и такого запаса индустриальной и кадровой прочности как оставил для Российской Федерации СССР там не было и нет. Читай что такое навязанное технологическое отставание.
I will assume these guys know that the original part was made of top-grade steel and carefully machined and hardened. And that wore out. So it’s a losing game to tak weld some tiny globs on, wrecking and remaining heat treatment. Not to mention hand-grinding new splines. Splines depend on perfectly uniform surfaces spreading the load out equally. You can’t duplicate that by eyeballing with an angle grinder. This machine will be back with two weeks.
They don’t have a choice, original part is way too expensive for them.
Welded parts must be heat treated even though it's welded right,so the structure integrity of the welded part won't warp or crack easily and always wear safety measure(s) while handling this kinds of stuff...
Отпуск
40 plus years in American mining, seen lots of professional repairs that didn't last. Need to admire these craftsman for their skill.
This shit won't last either. 😋
i agree for the skill , however this kind of job needs cnc precision, hammering that shaft to position dont think will ever work anyways nice try and skilful people yes.
You shouldn’t need a sledge to mate those 2. As long as it works and lasts I guess it’s good enough. I feel for the next guy who tries to separate them.
Can't understand what went wrong there, that's the second time this week they've had to recondition that same shaft, and somethings gone wrong with the live center/hammer now!
I don’t which part I enjoyed more, the dismount from the lathe at the end, or the installation of the sprocket to the splines shaft?
hey buddy, if you don't need a sledge to fit the splines then your not tight enough. lol
i come here often to have a great laygh and unwind from the day
omg, unreal
Fit like a glove, didn't it? Almost like it was made to.
Loucura, vocês são demais, um excelente trabalho e que pouquíssimas pessoas realizam. Valeu amigo!"
it's always a pleasure to watch you! But I'd like to watch a content about Moox. This ecosystem is too underestimated.
Honestly, the extent of negative, arm-chair criticism by posters who don't seem to get that these are the ONLY tools available to get the job done, is breath-taking. In a bad way.
Sorry if they don't follow Western heavy engineering standards, which of course cost vast sums of money, but I dare say these repairs have a useful service life, even if sub optimal, and getting the job done is, after all, the objective.
These people are running businesses. If they didn't provide value, they would be out of business.
Great use of available resources to get the job done
Wow…… Caterpillar engineers and technicians must be having heart failures after seeing this video. But…. The gear heat treat must be damn good to withstand repeat drops on the concrete. That lathe is taking a beating too.
Half ass fix just to keep it going until it breaks again and then another half ass fix .... Later they make tent pegs out of the final drive.
Beautiful work.
Like a butcher doing brain surgery.
very nb 很好，还能这么修， 非常佩服！！
The comments seem very positive, some just assuming they repaired this dozer or even manged to get the sprocket seated or separated again after that first attempt🤣
Jealous much
Кто знает, где выставляется данный художник?
I like the “outdoor” shop! These guys are true MacGyvers!!
Até a recuperação da rosca tudo bem! Problema é a chaveta da engrenagem! Eles não tem a ferramenta adequada! Mas trabalham bem nas condições deles!
Hard working informative video, dozer owner will be happy, and I am learning sign language as a bonus. I understand the cameraman's explanations :-)
I see lots of repair but this one is out of the chart ?!!🤪👍🤣
Never ceases to amaze me how these people that come from a dirt poor country and a very limited machines to help them and they still possess outstanding skills
You don't seem to know much about mechanical engineering. That is not skill, but pure botch.
@@gneuhaus8047 your right I ride and drive the shit out of stuff I'm not an engineer 🤔My point is if you lived in a crap hole like some of these poor people do then they are very handy with the materials and know how that they possess. I know people in this country ( America) that don't know how to change a spark plug ( literally) let alone create something, that was my point .
3 ring circus and the bearded lady is high as a kite thinking this repair will last.
Смотрел и зайчиков нахватался....капец
Wow, awesome lathe work.
That should get a D8 about 12 feet. Then they can pull it all down and do it again 😂
How did I know that these "master machinists" were going to re-form threads by pounding the fastener into the threads and re-cut splines with a hand grinder and a cut-off disc 🤣??? It would be interesting to know how many of those precision-cut splines actually produce drive at the same time!! And the "precision fitting" of the splines was beyond belief!!
Master machinist = master bator
It wouldn't be so frustrating if they explained why it was done this way in the description. And yes, hammering splines on, OUCH, wondering what this will fk up down the road.
It was really cringey watching experience.
@@Baisulis84 I was expecting 4 or more of these workers (butchers) to let loose with a mob of sledge hammers at the end, but only one was at it with a sledge hammer, only thing i can think is maybe they only had 1 sledge hammer.
I lost my faith when he started machining the shafts without any dial-in. But then he used a cut-off disk for the splines, so I guess precision was off the table before the work started.
Half Assed well enough to get it back over to the customer. Maintenance involves a call to the shop after weeks of the grinding sounds and clunking stop completely.
Зачем мелом затерают?
Так они и рассказали таинства хранимые веками 😜
это мыло
станок с чпу просто улет.
I take it that the mechanic putting it back together gets the honor of hand filling the splines to set the bushing crush.
Конструкционные материалы, материаловедение и прочие науки эти люди не изучали. Зубья восстановленные таким образом проживут от силы неделю.
I have to bite my tongue watching this stuff sometimes. It's easy for us in the west to be critical when we have all the systems in place, tooling, the latest machinery, expertise etc. These guys are trying to get by with bare-bones equipment that predates the turn of the 19th century. However, in saying that the Greeks built the Antikythera mechanism around 100BC so our ability to build precision equipment has been around a friggen long time.
Great video, that spline will peel like a banana when it goes into load.
Respect for the master
Это ужас все нормы нарушены, такой ремонт не нужен!
зато все буржуйские коментаторы кипятком ссут от восторга. а у наших волосы дыбом )))
Why don’t we see the shops where they produce sledgehammers? It totally has to be one of the largest businesses in these countries 🙃
10/10 dismount of precision machined part from lathe.
I believe that was a triple somersault and stuck the landing
@@criticaluplink9105 Glad to know I'm not the only one laughing my ass off.
Elinize sağlık. Parçayı sakıza çevirdiniz. Metalin sertlik derecesinin hiçe sayıldığı bir çalışma olmuş.
what is the purpose of the chalk on the threads?
Gotta love him using the live center for a hammer...
These guys should have just put the final drive back on the dozer, put the sprocket on there and wack it a few times with that sledge hammer till those precision grinder cut splines locked into the sprocket splines, then roll the whole dozer off the nearest cliff and hope the sprocket lands on the right tree stumps a few times and drives it the rest of the way on. JUST ANOTHER DAYS' WORK BOYS.
А зачем мел и мокрая тряпка, кто знает?
Думаю магия, и мел не простой, токарь им вдохновляется))
Это не мел,это кусок штукатурки дома единственного умеющего что то токаря,но он не выдержал пытки обучения этих клоунов,ушёл в китайский квартал)))
I like how he broached those splines.
Where can I get a box of those bent welding rods!
good job, perfect work ! respect !!!
Lol 👋😂👉you’re being sarcastic right!?
Bạn làm rất tốt thật tuyệt vời
This rebuild might need to wear in a bit
Жесть, как она есть :)
Lets face it. The work is rough as guts. Some of these videos show really good results with basic tools. This isn't one of them
Золотые руки👍👍👍
Amazing Skill 👌🏻
Clown
These videos are a prime example of how to destroy a lathe. I wish they would take care of their equipment, poverty is no excuse.
los paises no desarrollados se valen del trabajo artesanal para hacer que su maquinaria funcione, en los paises desarrollados simplemente cambian la pieza.
Looks like they are patching something up to run long enough to sell the machine.
Didn't see the final fitting together. Maybe it's still sitting there stuck together.
Наделали херни и думают, что же не лезет
The only amazing I saw was the dirt the men working in.
Wow I've never seen that done. What percentage of hours do they get compared to new one. Yes they could probably rebuild this three times for the price of new. Those tapered splines need to be sweet to hold sprocket flange on.
I KNEW THAT SLEG HAMMER WAS COMEING OUT TO PLAY 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Have no fear . . . .I got this new angle grinder here !
This video is a joke right ?
Not a chance this thing leaves the parking lot under it;s own strength !
There is the old saying, never do a half-ass job, only do the job that you would be proud to put your signature on. These people apparently have never heard of that particular old adage and therefore they make their repairs on machinery about one step above being labeled as a Neanderthal repairmen with tools. Correctness and Precision are not words within their vocabulary nor are those words in their mental understanding of what is required when making specific and crucial repairs.
Saw this whilst serving in Malaysia the were repairing a blitz gear box on there logging truck
Way back in the sixties
AMAIZING WORK WHY THEY ARE NOT GIVEN PROTECTIVE GLASSES/?
if you die you die , hence all the ambulance sounds .
He actually had a guard on the grinder which is better than most of the tips monkeys on CZcams
I would suggest to design a tool so you can fix the grinder on the carriage.Great job!
As a "confirmed gear-head"... I'll I can say is OH MY.
Caterpillar must be so pleased with this "repair". Guaranteed sale of a genuine part soon. Or just goes to show how wrong the Western World has been all these centuries to create and impose engineering standards. Silly us. LOL
I absolutely cringed when he goes at it with the jumbo sledge. I was wondering how they were going to get a precision fit to the final drive sprocket. That will be a precision tight fit alright. I wouldn't be surprised if they weld the drive shift to the drive sprocket! I've seen things like this in my travels!
I’d guess they’re pretty good at keeping wore out dinosaurs going. I’d bet that machine was wore out when it headed there, and they’ll keep patching it up forever
I was wondering what sort of mill they were going to cot those teeth with.
I ran a big old mill 40 years ago ,used 440 volts . But it was much newer than what they are using .
But if you have skilled people, you an accomplish unbelievable results.
Many levels of wow and shock here but what is the lime or whatever on the threads for, first I thought sanding as no paper, then I thought lubricant but then there was some. What was it 🤔
I think it was soap, or maybe chalk mixed with the oil? idk anymore
I think…🤔…yes I think it’s a “MAGIC POWDER”. By it at least he can see and measure the thread depth bcoz there is no thread cutting and measuring tools. So he put this Magic Powder to control his hand as CNC controller.
Have I just watched someone cut a spline with an angle grinder 😂
Very wonderful
Thank u
Is there a part 2 where they used a bigger f ing hammer to get the gears to fit properly?
Those welds aren’t going to hold, they are just spot welds and not gotten hot enough to heat up the metal underneath it to bond them together. What a waste of time and money.
В принципе, если не ездить, то надолго хватит.
Remind me not to do business there! 😂😂🤣🤣
It was like watching a snuff film, you know it is all so wrong but you have to keep watching......
For some reason I found your comment as the best one yet.
