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 !!!!!!
ШЛИЦЫ БОЛГАРКОЙ Я ЕЩЁ НЕ ВИДЕЛ КАК ДЕЛАЮТ! 😁😁😁
Воч ю сей нигга эври бади фак ю?
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
У них не получилось, потому что какой-то хернёй начпли мерять. Надо было рулеткой, от начала и до конца, тогда бы всё влезло :)))
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.
@@АлександрУваров-л8ц так там какая металлоёмкрсть и размеры, а обороты???
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.
@@ВячеславСемёнычев-о8х 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
😂😂😂😂
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.
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.
Жалко не показали как они её обратно выдергивали:)
it jamed !! :D
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! 💪💪🙏🙌🙌
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 😂
Когда увидел в руках болгарку я понял -это конец сей басни закономерный , какие еще размеры вы о чем?
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.
))) надолго ли этот "ремонт"? мои сочувствия заказчику. How long will this "repair" last? my condolences to the customer
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
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.
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.
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.
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
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.
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.
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.
Да нормально он все сделал . Дайте его номер у кого есть , хочу гидроблок на коробке автомат восстановить
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.
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
I'm sorry to say that somewhere during this entire process the patient died
Awesome video and hardworking people.
Кто знает, где выставляется данный художник?
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.
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.
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.
I see lots of repair but this one is out of the chart ?!!🤪👍🤣
Where can I get a box of those bent welding rods!
All the commentors below seem to be forgetting one thing as they criticize the quality delivered, or failed to be delivered, here. The owner of the bulldozer came to the shop, and said, "I have $100, do the best you can with it, please. It's all I have in the world. I know it can't be great, but something is a lot better than nothing"
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
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
Great use of available resources to get the job done
These guys do an amazing job with no resources but having worked for Caterpillar for 20 years including the D8 assembly line this repair is destined to fail.
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.
Конструкционные материалы, материаловедение и прочие науки эти люди не изучали. Зубья восстановленные таким образом проживут от силы неделю.
Смотрел и зайчиков нахватался....капец
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!
Why don’t we see the shops where they produce sledgehammers? It totally has to be one of the largest businesses in these countries 🙃
I take it that the mechanic putting it back together gets the honor of hand filling the splines to set the bushing crush.
Didn't see the final fitting together. Maybe it's still sitting there stuck together.
That should get a D8 about 12 feet. Then they can pull it all down and do it again 😂
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.
Wow, awesome lathe work.
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!
станок с чпу просто улет.
Жесть, как она есть :)
I am glad this mechanic is not a Brain Surgeon, his patients would be walking sideways.
I like how he broached those splines.
very nb 很好，还能这么修， 非常佩服！！
I WONDER WHAT WARRANTIES THAY GIVE . 1 HOUR OR 2 .
Saw this whilst serving in Malaysia the were repairing a blitz gear box on there logging truck
Way back in the sixties
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.
Beautiful work.
Like a butcher doing brain surgery.
Great video, that spline will peel like a banana when it goes into load.
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.
I KNEW THAT SLEG HAMMER WAS COMEING OUT TO PLAY 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
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.
I like the “outdoor” shop! These guys are true MacGyvers!!
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.
This rebuild might need to wear in a bit
В принципе, если не ездить, то надолго хватит.
مايصلح هذا الشغل تروس تصلحها بصاروخ هذي ماتكمل شهر وخربان وغير كذا تركبه بالشاكوش كيف بيطلع ذا للصيانه
Зачем мелом затерают?
Так они и рассказали таинства хранимые веками 😜

I would suggest to design a tool so you can fix the grinder on the carriage.Great job!
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.
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.
Франция. 16 век. Винтаж !

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 !
Это ужас все нормы нарушены, такой ремонт не нужен!
зато все буржуйские коментаторы кипятком ссут от восторга. а у наших волосы дыбом )))
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.
Hard working informative video, dozer owner will be happy, and I am learning sign language as a bonus. I understand the cameraman's explanations :-)
Is there a part 2 where they used a bigger f ing hammer to get the gears to fit properly?
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...
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)))

do what you must."we dont have one of these but.. we do have one of these...
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.
@@stevenhorne5089 Ha Ha thank you!
The only amazing I saw was the dirt the men working in.
These machines will work well. If the caterpillar agent do this repair, it will be more costly and not affordable. It doesn’t matter how much we spent for the repair, if the operators not caring of the machine it will break down anyway..
Beaucoup de travail, pour quelle durée de vie?
It’s hard to accept as western skilled engineers, ( I did 5 years toolmaking and two more as a Jig Borer!) that they would even attempt this methodology, but they do pull it off, whereas I doubt we could even attempt it!? I’m a good bodger too, but that shows an inate skill that these people have inbuilt, it would seem! Needs must , when the Devil rides, so hats off to them for endeavour! I guess too, that they could claim...fully ground finishes on all surfaces! Bloody brilliantly done, in the dirt! Cheers
Cutting the welded gear teeth with a handheld angle grinder, then dumping the whole assembly on the ground... yeah, no....
Золотые руки👍👍👍
Have I just watched someone cut a spline with an angle grinder 😂
На сколько хватит зубьев!???
Это как газовать будет 😂
Amazing Skill 👌🏻
