These guys using amazing skills for repair stone crusher machine, excellent teamwork for restoration 👇 @mimechanics1019 #Crankshaft #AmazingMethod #Restored #Beginning #restoration #amazing #teamworks
Сидишь себе в хлопковой рубахе, в шлепонцах на босую ногу, голыми руками и вариш железяку электро-сваркой, а над тобой проплывает на стареньком тельфере вал механизма тон 5. Романтика🤐
У нас такое тоже частенько. Сам помню не мог понять как можно расколоть подш типа 3640 или 3538,стоит в подъемнике-манипуляторе пока не узнал что температура ночью была - 30.Греть пос отверстие ни кто не посчитал нужным.
Я когда на заводе работал, тоже решил на печке подшипник нагреть и он легко так сел на вал)) Мастер потом увидел, лишил премии и заставил заново насаживать другой)) А тут норма)) Долбоебы
@@trashcanmucous5153 and shaft is still bent,,,,dont know how that shaft is used but if they like it its fine with me. No welding helmet, no safety items anywhere, and seems to be a dirt floor
Right! Should have just used mud. And they apparently don't believe in impacts! Must be paid by the hour which probably doesn't amount too much. They're extraction method should be used by all SWAT teams for dynamic entry. Lol
It’s the main pitman shaft for the swing dye in a Jaw crusher, it’s designed as such. The lack of safety gear is also very sad. Next time someone bitches about their jobs, they should think of these guys.
Will they lubricate the shaft and bearings properly when they are put back in to service? Did they install new seals? If not it will fail again. It was probably never greased.
I served a five apprenticeship as a fitter and turner on the copper mines in Zambia. I was taught by old school artisans who took a pride in the work that they put out. If they saw this video I am dead certain they would turn over in their graves!! (God bless them). This is unbelievable!!!!
Dear Pakistani skilled workers you are the best in the world. Without proper tools or even safety equipment you make these big Machines work again. GOD Bless you brothers. Pakistan Zindabad. Long live Pakistan.
Agreed...That was one of the ugliest, filthy, mechanically unsound large repair jobs I have ever witnessed...It is set up for failure...They earned the third world label that day...
Those special run in dirt bearings. We don't have any like that here. The ones we have would be destroyed in minutes by the abrasive dirt. Can you imagine what these guys could do with a clean floor and cleaning solvent!
They will start from bringing the sand. They have many opportunities to make real floors and use modern ways of work. But they don't care and don't learn.
@mister kluge Show me, when they washed the bearing from sand and dust! Not only "cleaned" it with dirty rag with some liquid in shitty color. After that kind of treatment bearing has to be rinsed out with solvent, lots of solvent, and new grease has to be applied.
These guys use Coke, the truck guys use 7-up for cleaning solvent. I wonder which is better? I almost forgot, The Giant Swing Press is just right for seating those big bearings. And I wonder if SKF approves of their bearing heater? What could possibly go wrong?
Son una maravilla de mecánicos, ingeniosos y por sobre todo un trabajo en equipo que da resultados. Desde Chile un fuerte abrazo a las ganas que ponen en lograr su objeto. Todo mi respeto a ustedes, con lo que veo también aprendo.
I am in awe of the creativity of these amazing people in the absence of tools. Their knowledge and skills are stronger than the most modern tools. Respect to heaven!
The guy doing the lathe work and the big happy smile and thumbs up almost had me give the thumbs up back. It seems the lads personality is catching, given the main workers smiles and thumbs at the end. Outstanding job and that WAS a humongus looking lathe but for it all, the "ram" on on the crane chain did it for me had me applauding their ingenuity..
The 'Ram' on the crane idea has been in use since the start of engineering and was still in use in British heavy engineering up until at least the 1960s. We used to call it a 'Tup' and it was a common way of 'shunting' something very heavy over a short distance.
these days ago we changed the bearings of a calender, these bearings weighed more than 750kg, even with all the tools available and equipment it was not so easy to change of bearings and shaft machining, great teamwork, God bless them...

I'd love to see what that "crankshaft" is used on. It looked more like a giant camshaft. My only real concern was seeing the bearings rolling around on the dirt floor. Regardless, those guys did an amazing job considering their working conditions etc. Pakistan would be a much more prosperous world-player if the government worked as well as this team. I worked as an oilfield drilling electrician in Quatar UAE. I learned all about ingenuity and how to "get things done" from my two fellow electricians, Mr Jacoob & Hadji from Karachi in Pakistan. In 1977-8 I was a drilling newbie, and they saved my ignorant ass every single day. I was ashamed that my salary was 5 times theirs, but they still treated me with the highest respect, which I greatly returned. God bless you Jacoob & Hadji.
Thanks for your comments Brian, I see a lot of very nasty, childish and spiteful comments from Westerners on these Pakistani workshop sites. I am not sure why ? Possibly nothing more than racism coming from ugly bitter souls ? Anyway it's great to hear your positive perspective. And your great respect for Mr Jacoob and Hadji. 🙏
@@jackb8682 you're very welcome Jack. Jack was my Father's name too, and he was an engineer, mechanic, machinist (English Army) just like these guys. You are correct in your assumption that ignorant racism is the core reason for the silly, childish & nasty comments posted regarding these "helpful and educational" videos of how the different work-forces of other cultures are countries work to achieve the same objectives. It's ignorant racial snobbery, plain & simple. I hope you have a beautiful blessed day, Jack. Cheers from S.Louisiana USA.
Thank you for your appreciative comments, I agree that it's very easy to criticise what appears to be their crude and laughable methods but they are using basic engineering methods of applying heavy directional forces in the safest way that they have available. I'd like to think that just by watching this video a few westerners have already been 'educated' I had a similar humbling experience to you when I was installing British built heavy machinery in Karachi in the 1970s. Despite having hardly any lifting equipment they taught me how to make do with what was available. Hat's off to your Mr Jacoob and to your Mr Hadji.
Safest way available? BS. It is the cheapest, not safest. They could make and use a threaded puller that would only cost a couple dollars to make, but they dont.
I have never seen one of those large handraulic hammers before along with crunchy nut dust grease lubricant, top safety tip of the week, use sandals with the steel toe caps covered in a cloak of invisibility, all happy and smiley in their work.
This is Pakistan Not every man who works here wears safety equipment Me too, I have been working as an electrician and plumber for 20 years It is very difficult to work wearing safety equipment. Helmet or gloves.
@@nadeemnadeem-mb4od it is difficult but worss if you get a crushed food or eyeball gets poked...shop owners should make it mandatory and money should not be the issue....these guys can make anything out of nothing
реально молодцы люди без школы университета попали в такое время технологии.... молодцы аж помочь им захотелось,реально тяжёлые времена принесут сильных людей
Amazing techniques and very hard working people. For such companies investment in heavy hydraulic presses will be not a bad idea. I wish good luck for these hard working people.
The tool big enough to accomplish what they did with hand tools and ingenuity probably costs what that whole teams wages are for a couple few years. Not worth the investment if you’re only going to use it every few years.
Unfortunately, heavy hydraulic presses are hugely expensive and can only be justified if they are in constant use. These guys are using their initiative and skills to get a difficult job done with what they have available. They are good hardworking people.
Micrometers and dial indicators? We don't need no gauges; we have calipers and rulers and chalk. We can do OK. Very satisfying to watch these folks get the job done. Thanks for the channel. Liked and subbed.
looks like part of a rock crusher if i had to guess... love when the guy starts singing and it sounds like alvin and the chipmunks!!! cool videos, im glad i found the channel...
😁Я бате давным-давно, когда ещё учился в универе, пошел помагать ремонтировать автобус. Так у него одна из проблем была, это зализало зубья на венце маховика(запчастей на базе небыло) . Так он взял болгарку и между зубьев сточил эти зализы. Я стою и говорю, что меня дрючат в универе про эвольвенту, про модуль зуба и т. д. Он поржал, завел автобус и поехал. Понятно, что такой ремонт мягко говоря не надолго, но как история про практика(которому семью нужно содержать) и теоретика-студента занятная. Жиза!
Молодцы ребята! Да и дробилка серьезная. Вот смотрю я ваши видео и все время думаю, что вы могли бы сделать, дай вам нормальное оборудование и инструменты?
валы на щековых дробилках наваривать нельзя ! бывает после этого обрыв вала и маховик 5 тонн весело и долго катается по карьеру сметая всех@@user-th1dr1gy7h
@@user-vd3vi5eb7p как раз думал о том, подлежит ли ремонту данный вал... Не будет ли после неравномерного термического воздействия напряжения внутри металла
Ещё крайне необходимо хороших технологов и ,как минимум, понимания процессов,происходящих в металле после их обработки Но ничего! Зато с таким подходом работой они будут обеспечены всегда. Меня очень также порадовал мерительный инструмент,при помощи которого они проточили посадочное место под подшипник!Просто для космических технологий точность! PS. А ещё надо чтобы кто нибудь научил их хотя бы элементарной заточке токарных резцов.
Каковы молодцы! Накидали грязи и окалины в подшипник. Хренячили железякой по торцу оси, а потом стали там искать ни разу не забитое центровое отверстие, размеры снимают на ходу. Блеск! 😆 P.S. 23:00 - динамометрический ключ. )))
I have the same box wrenches they use. Bought mine cheap at a discount store 40 years ago and even though i've got lots more expensive wrenches I still use those. They have been abused badly, heated and bent, piece of pipe for leverage, etc and they never fail. Love that huge battering ram!
Definitivamente uno nunca termina de aprender , que maestros con más ingenio que tecnología hacen un trabajo explendido Soy mecánico matricero desde el año 96 Saludos desde Perú
What, exactly, was the repair here ? They welded & turned the journal, which leads me to believe the inner bearing race had spun on it, yet they re-used the same bearings (after rolling them around in dirt, of course). Wouldn't the inner race be scored if it had spun enough to destroy the journal ? I think Pep Boys keeps those bearings in stock. 😆
Bearing races are very hard, the shaft is softer. Vast majority of damage will be to the shaft. The shaft was built up enough to make a fair interference fit on the race ID, so at equal temperatures there won't be appreciable slop. "Perfect job"? Of course not. But it will do what it's supposed to for quite a while. It's a crusher not a jet engine lol
The journals for the outer bearings were worn, when they first removed the bearings you can see little dots on it, that is where on a previous repair they had peened the journals so the bearings would be a tight fit. Obviously the peening did not last, how long this repair lasts is unknown without at least a semi accurate interference fit.
Техника безопасности? Не, не слышали 😂 штангель циркуль? Нафига, линейка есть старая... Про песок и отпуск металла... И так сойдет... А в целом молодцы, вам бы условия создать, обучить, вы корабль космический соберете...
Действительно сам то можешь работать циркулем? 😂а то видел всё есть условие инструменты у таких которые говорят техника безопасности? Штангель а руки всё равно иж жопы эти ребята вынуждены работать в таких условиях вынуждены блядь дать им то что у вас есть они вас по всем фронтам по имеют
To the talented, hardworking men in these videos: if I were a wealthy person, it would be a pleasure & honour for me to build you a beautiful new modern workshop with a concrete floor, better lighting and all brand new machinery. Please keep up the good work. Btw: is this large shaft project part of a rock-crushing machine?
No first aid box seen,not one fire extinguisher seen,no health and safety posters or Marshalls. No boots, primitive tools. They make our engineers look erm maybe too polished? Awsome job guys. I would employ you all. 👏
