Молодцы, в таких условиях с минимумом оборудования сделать такую работу. Делают ремонт тем инструментом что у них есть. Хотя наплавка с последующей проточкой болгарской кажется не самым лучшим вариантом но видимо у них есть специально обученный оператор болгарки который может обточить болгарской с точностью токарного станка
какую работу то? Догробить до конца то что еще можно было спасит и насрав сваркой и шлифанув болгаркой на глазок? Ты вообще что такое точность и термообработака знаешь? Цементация там, закалка... не, не щелкает ничего в голове?
После того как я увидел обработку посадочной поверхности под подшипник болгаркой, я понял что ребята с таким же успехом могли бы таскать валуны из угла в угол, результат был бы тот же 😂
Чувак из Австралии Сutting Еdge - я делаю вещи! Так как я ни кто не может. Какие то чуваки с Ближнего Востока - подержи моё пиво!!! С помощью головки на 32, одного лома и плоской отвёртки раскидали половину карьерного бульдозера и обратно собрали.!!!
Most anywhere else on this planet ...hospital emergency rooms would be overflowing with bleeding broken bodies. OSHA was created to protect workers with the a minimum of PPE standard that employers failed to provide, and it is still a minimum . Worker diligence is another matter altogether ,what these men do with clothing and footwear that would get westerners killed in the first 15 minutes of their shift is truly impressive, let alone hearing , eye protection or gloves , and get it done for wages that westerners would scoff at. I retired from a long career as an industrial mechanic , industrial stationary machinery. Curiosity drives me to watch these videos ,not for entertainment but to remind myself how good my working environments were by comparison to what these men have , and still bitching and moaning about them more days than not . MUCH RESPECT TO ALL IN THIS VIDEO WHO WORK SO HARD ...👏👏👏👏, 🙏 for your safety .
Thanks for watching and comments 😍❤️, right don't care about safety here. It's important. Workers get $7-$15 per day for hard work, lift heavy parts without any machine. So owner should provide them safety equipments, but they don't.
@@wes11bravo - Simple, bro! Did it ever occur to you that safety is a part of human rights, which is an absolute concept anywhere in the world? But the Russians for some reason thought about it ...
@@meytv5691 Наваривали мы на двигателя 600 КВт, на валу посадочные под подшипники, без проблем. Все зависит от металла электрода, мягкий разобьет сразу.
this is the most ridiculous comment i have seen yet concerning one of these videos! you want to go there and be a mechanic, your toolbox consists of a 6 ft. iron bar, a huge sledgehammer, and if your rich enough an acetylene torch. if your truly not lying i feel sorry for you and your perception of what our kids should take lessons from.
В общем то даже в США наварку делают. Но нужно ещё поискать мастерскую, которая во первых наварит не что попало, во вторых имеет станки для стачивания лишнего. Большие запчасти стоят очень дорого. И наваривание выгодно даже в странах с высоким уровнем жизни. Конечно та порнография, что делается в видео, никуда не годится. Во первых электроды, самое обычное железо, а не специальный сплав, одинаковый по составу с ремонтируемой железякой. Во вторых обтачивание болгаркой на глазок. В лучшем случае несколько месяцев он проживёт до ремонта.
@@administracy Нет. Чем больше и массивней деталь, тем дешевле её починить, чем купить новую. Это работает даже в стране которая и производит конкретно эти детали. Если это несъёмная деталь рамы, то и говорить нечего. К тому же деталь могут давно не выпускать, т.к. техника устарела. А выпуск её сторонними производителями для открытой продажи к примеру в том же США запрещен законом. Даже крупные мастерские изготавливают для ремонта относительно простые детали. Различные шрифты(размером метров до двух), петли, шестерни, детали гидравлики.
Sie sind sehr sehr gute Spezialisten in ihrem Fach, einmalig ! Das kann keiner mehr in Deutschland, bitte kommen sie zu uns nach Deutschland, wir brauchen sie..... Liebe Grüße aus Niedersachsen
Of all the personal attributes that these guys have-- brains, balls, know-how, courage, toughness, the one characteristic that accounts for their success is COOPERATION.
болт крепления оси редуктора сзади слева так и не докрутили... все думал когда докрутят, а они гусянку уже цепляют... А один так театрально крутил болты на шестеренке, хотя они были зашплинтованы)

The world knows the people of Pakistan are suffering from extremely high costs of living. Hope you keep on making vids showing the hard work of the Pakistani people.
I feel like I’ve learned more about servicing the track drive system on a komatsu dozer in this video than any training video put out by Komatsu. Just watching these guys do this on super hardcore difficulty is impressive. I would never trust a single thing they resurfaced by piling weld on then grinding it to “round?” That’s sketchy as fuck but hey what else did they have to do it with? Let’s all be real for a second though. That pry bar/breaker bar/lifting bar is the real MVP. Hardest worker on the crew. Lol
Well that just blew every theory I had about how it should be done. I'm off to buy a 5 inch grinder to seat some bearings. Imagine buying that machine next month and realizing you brought a lemon.
Despite the lack of capabilities and the barrier, you have great skill and patience, our Pakistani brothers. May God help you. You deserve the best workshop in the world to work in. You have all our love and respect.
@@dell7054 Oh, believe me, I understand. Hope they are making a few bucks from You Tube. Some of the things they do with heavy equipment is totally amazing!
It's incredible how little they appreciate their life. They cut and grab things without any protection, they believe that if they lose their sight they will grow another leaf or arm.
already imagine how long that poor machine gona gonna work after such reparation lol. But on another hand those guys are real heroes, working almost without tools
Really wonderful work. Although all parts are way heavy I see great proficiency in all movements! I myself would have no idea how to perform that with tools and in conditions you guys have. Great job!
It is skill to work with low or no resources.With facilities it is just procedure.Having worked in a factory making these dozers I can say only one thing "Awesome"
I wish I was there so I could offer helpful instructions like "Hey, don't scratch that!" 😀 This is impressive, I just wish these guys had some better equipment and safety gear.
While these guys are very crude they do get it done! It’s amazing how they have the most basic tools. Even their machinist don’t have any micrometers, dial indicators, etc. Bearing removing tools or installation equipment - hammers and chisels. Utterly amazing. I wonder how long these pieces of equipment last?
That’s my big question, and probably THE big question… how long does it last???? Maybe I’m a pessimist, but I can’t believe the bearing where they were welding and grinding lasted too long before it spun. However, I’ve seen fixes that don’t look like they should last 5 minutes, work for years.
А наши слесарье делают тоже самое, только в холодном боксе, на Кольском полуострове. Завтра покажу им, пусть пакистанцам завидуют. P.S. Со сварщиками у нас получше. 😀 (Интересно, как по-пакистански будет "ГЛАЗАААА!"?). Кабина у автокрана-класс!
Amazing repair...I had to do the same to a Cat D6H where the final drive axle was damaged...we certainly didn't think of rebuilding the damaged axle with weld..amazing...we had to obtain a new stub axle at great expense and removing that was a nightmare... fantastic in the field repair...👍👍
I've got an old d5b 3306 non turbo power shift 96j series which is an old d6 non turbo pre d6c manual platform. Had final drive trouble all the time. Had to put many dead axles in it. Used liquid nitrogen to freeze it and press it in. Or, liquid propane. Couldn't afford the Cat dead axle so usually blight aftermarket. Looking back, maybe the hole was wallered out up in the rear housing. May have needed to be welded up and lined bored or the rear housing replaced. Would take the idlers to Heavyquip and have then welded up with new bearings installed. Didn't know a rough weld like this would make sense. Seems to be abrasive on the rails. But in a country where resources are limited you may just have to do it the wrong way to get the job done. Might have to take a few steps back to go one step forward and that's all you can do. Sometimes you have to lower your standards to survive. I love watching these videos.
As long as it isn't cracked, that's a common repair for inner or outer surfaces. However the 'round it out with a grinder' ensures this will fail again in short order.
Нормально прям вспоминаю юность тогда тоже нифига не было и сейчас смотришь и вспоминаешь мужиков которые ремонтировали трактора и бульдозера и хорошо если лебедка или цех свободен а попробуй на улице из коробки через кабину поросенка достань через люк а он насколько помню около 70 кг весит а мы помогали это сейчас гайковёрт болгарка мясорубка шуруповёрт а тогда лом кувалда а если совсем ни как то грели автогеном
Great effort but I have one reservation when you’re welding an axle or shaft that big you need to heat it up before welding otherwise it will break you can’t weld it when it’s cold . The weld would not penetrate deep enough into the metal. You need to heat it up to 180F first it needs to be red hot.
With some small exceptions Farenheits are black magic for non Americans... so not point to talk about them. But you said that you want the steel to be red hot, that is somewhat more understandable, the only thing that is not is why do you think that you need to pre-heat stell so idioticaly high... I wasted whole 2 second in google to find this: "For thicknesses of 3/4 to 1 1/2 inch, the minimum temperature is 150 °F. For thicknesses of over 2 1/2 inches, the minimum preheat temperature is 300 °F. These minimum preheats become somewhat lower for Category B steel (A572), and AWS D1."
You guys are very skilled. You do things with much less technology and you do a great job. In North America, we have to send everything away for machining and rebuilding. It costs the customer tons of money. It is unnecessary.
I really like the way these men make do with what they have and they get the job done , reminds me of when I use to do all of my own mechanical work , I did not have luxuries like these men I made do with the equipment I had.
The easiest way I have found to get a dozer on jack stands is to place a wedge behind the tracks and back the dozer up until I could put a stand under the rear of it. Once you get the stands under the rear, place the dozer in forward with the blade down and kick the wedges out from under the track. I then use the blade to lift the front end high enough to place a stand under the front then I raise the blade.
While I admire the skills shown by these guys I also have to admire the amount of brute force they need to employ to get the job done. It's probably the reason why overweight people are few and far between.
I'm never going to complain again about my car wheel nuts being to tight to open😂😂😂 To the idiots critising about lack of safety. These guys do what they can with what they have. "Modern" methods, you take 3 7 hours to do safety training and put on your safety gear...then spend the balance of the day, letting machines do all the work and call yourself engineers 😂😂😂 Learn how its done from these guys. Trust, teamwork, dedication and just plain hardwork. Most the world's greatest things were built long before safety was even thought of
