To all the comments on how imprecise and unsophisticated the whole repair process is... clearly this mechanic is making the best of what's available to him. I'm sure all repair shops in your area would label this broken axel as beyond repair and make you get a replacement. However, in places where people lack the wherewithal to get such replacement part, having talented mechanics like this lad is invaluable and crucial to the proper function of their society. I'd say it's a job well done!
@Cyclery M Carissimo,un lavoro del genere *NON* risolve alcun problema(a parte riempire le tasche del "meccanico"),tra pochi giorni il cliente resterà a piedi con la differenza che avrà sborsato tanti $$ per non avere alcuna riparazione...,che sia difficoltoso reperire ricambi non è un problema del meccanico ma del cliente,se il cliente è disposto a rischiare allora è tutto ok,sai come si dice in italia?,cornuto e mazziato.
I have had to make do with less before. Put off repairs, budget to get things done. These people are from a poor country. Power tools save time and cost money. New parts are just as expensive in Pakistan as elsewhere and new vehicles are very expensive compared to what an average worker makes, there.
I never get tired of watching this man repeatedly repair essential mechanical trucks parts it’s a lesson in precision engineering adaptability and a macgyver of all the tradesman wonderful legacy and viewing
Интересно было бы, если бы собрать машину из всех деталей, которые на ютубе "чинили". Мотор с коробкой собранные в песке, кардан сваренный из этого ролика, и Редуктор с наваренным зубом хвостовика)))
I always see derogatory comments here, but these guys live this reality and fight for their livelihood. Congratulations on overcoming adversity! Cheers from Brazil!
Алат на третиот милениум: чекан, сет за заварување/сечење и флексерица (брусилица). Со оваа опрема момциве ќе поправат и ракетен мотор на Спејс шатл "Колумбија". Храбри момци, вешти и генијалци на својот занает ... БРАВО.
Текнолоджи, конечна, амазингы... Особенно поразила динамическая балансировка и ремонт посадочного отвестия методом электродного напыления с последующим шарошингом! Про сборку вообще слов нет, ну и результат - просто шикарен!
@@user-tv3hi1fb5c дура ты ворона, да, запчасти были к советской технике, но через месяц, а сено не ждет, кстати техника немецкая была и наши запчасти к ней не подходили. Рук таких теперь не найдёшь. А тебе в голову насрано, хотя, давно известно, что вороны говно клюют.
My first thought also. I see them build a lot of big things that would not work on a bench but everything else. The dirt, the bending, loosing things....
Older Drive Shafts are made from medium carbon steel, so preheating 200°C-300°C is required before welding. the repaired part then needs to be cooled slowly, then stress relieved at 550°C - 660°C.
@@pamlabrecque7430 if you don't preheat & stress relieve as per welding rod manufacturers instructions the part will have a very short life, & it will likely fail catastropically. It will need to repaired again & again. Vehicle Safety cearly isn't a priority in this country
@@PD-yd3fr I would not call myself a welder I would not even know how to weld say a broken trunnion on a td-7 or a cracked differential yoke on a tractor I would just preheat it to about 200 -300 degrees then super glue it I was just commenting about those guys fixing a broken driveshaft with what they had Much Respect
I see a lot of comments putting the guys down . I'm sure with some top of the range tooling and a fully kitted shop the outcome would possibly be different. A lot of bits I disagree with , the nice clean rag wiping the crap off placed back on the dirt and then picked to wipe the next bit clean... belting the shitz out the shaft after welding it all up , the steady rest being used to carry a piece that wasn't centred or I suspect even round so it's not going to be central . I love the drill bit wandering all over but being held somewhere near centre. All in all we don't know if this was a repair to get a vehicle back up and moving to another shop till a better replacement can be located or as I suspect a full repair . However you gotta love these guys doing their best with what tools and resources they actually have available.
Hopefully you read this! Do you happen to have a contact email? I would love to get in touch to send some tools your way for some more accurate machining! Like an indicator or two for that Lathe for picking up the round surface instead of the feeler you use and some stuff like that! Sending love from america!
They repair will last exactly as long as needed! From Gujarat to New Delhi...or where ever that is. Repairs in this of the world are just temporary! Greetings from Cambodia!
Ooooh. BAD. Bearing caps are a loose slip fit in the socket end. They will be wallered out in no time. You need a light press fit. That way, there's no hammering of the housing ring as the power is applied, then withdrawn. All the engine's power is endured by those U joints.
I have been there brother, no clean floor or solid iron tables to do your work, people over here in the states does not understand that in places like yours things get fix the best people can. good job . And any way if it breaks it will come back to get it repair again lol.
I have seen this guy in other machine shops on you tube. He's good enough to have his own machine shop somewhere. I wish he could come to America. I wish him well..
Well maybe this isn't right and that's not right but I'd say it's pretty good for a guy working on a dirt floor an old stick welder and wearing sandles!
You make do with what you have. The money these trucks earn is little, and they need to keep working. The crude repairs using simple tools is all they have in a country where labor is ridiculously cheap. The value of human life is low, if a man is killed or injured they just find another from the vast pool of replacements. Using ancient machines dating from the days of British rule and patched up many times it is truly amazing how these men keep their society running. Look at how out far it is from being true. And those needles, what's left of them in the u-joint. Truly amazing if it lasts a few weeks. But in a society of cobbled together machines and crude tools it's an amazing feat these men perform. Imagine what these people could be under different circumstances.
Guaranteed 30 feet or 30 seconds what ever comes first. That thing it going to fail real quick between the sand in the bearings and it being out of balance yeah not good.
The sad thing with thing with all of your comments out there is that most if not all would either go to a junk yard or order a new part, but If you had to make a repair like this many could not if that was your only choice. I would love to see someone do this repair with little to no power tools brute force and similar equipment and do a better job and post it.
В Е6едях, в дали от дома и запчастей ноги целовать ему будешь ! А то и в ж0пу дашь...!!! 😜😂 Тут бы доехать ! А так согласен ! - Не рискуйте !- Хyйня полная ,от начала и до конца !😢
I have watched several of this fellows videos, and I must say he does outstanding work. But I take opposition to how he tacks the inside of the u-joint bore hole here. The cup of the u-joint must be dead center in its bore hole and be very snug fit otherwise it will vibrate when rotated at high speeds. He should have welded all away around the bore hole then drilled it out to the correct spec diameter. His welding with a stick welder is exemplary! Also an excellent lathe operator. Just wish he would wear safety shoes!!
That shaft appears to have been repaired before. Note the difference in materials on the broken shaft, with a HAZ apparent. Also, it appears to have voids in the outer part of the shaft from previous poor welding. I suspect after this repair it will inevitably fail once more.
Przed toczeniem tego czeba było to przed sfazowaniem za kołkować a nie składać to i dla czego tam pod te pokrywki nie jest dane tam smaru i dla czego jest przytoczony spaw przecież ten spaw został osłabiony i przecież tak jak tu jest zrobione tak się wogulę nie robi pozdrawiam twórcę tego filmiku mile i serdecznie 👍👍👍👍
The best Welder I've ever seen. (Какой НАКС, какой ультразвук или рентген? И пох, что корень как пемза. Какая молибденовая смазка для игольчатых подшипников? И ведь работает... Молотком чуток поправил соосность и пошёл ставить на луноход. )
Thank you Sir for your excelent work!!... Gob bless you and your families and friends where ever you go... Best regards from Santiago de Chile, South America!!!
A speedy way to fix it but not the proper way. The worker may be innovative but not efficient. This way it may look fixed but it may develop some other crazy problems. It may be satisfying to some of us but it's not right.
Another unbelievably bad bit of machining and repair. It won't last more than 10 minutes as soon as a load is applied to those needle roller bearings, plus the vibration from it being welded up eccentrically.
That's just a matter of common sense; the guy went all the way to fix the shaft, replaced the U-joint for another used one, but never bother lubricating the bearings and besides of all, let the bearing case loose inside the U-joint. Come on! You can do better than that.
шараш-монтаж. Крестовина держится за счёт двух болтов, болтается в копыте как хер в стакане. Интересно, сколько метров с полной нагрузкой проедет этот пипелац.
I would like to send this guy a lot of tools.. He keeps his lathe clean. I thought the same thing as others did, why weld the complete assembly. Several reasons that I see, is balance, correct length, and chucking a half trunion is difficult in a lathe is difficult. The bearings were well protected and obviously did not get too hot, one these universal joint needle bearings and cups are designed to withstand a lot of heat. He is a master at what he does. He has learned to silver solder carbide tips on his cutting tools. Yeah, I would like for him to get out of the sand. But it seems as they keep critical parts clean...well, sometimes. I send him much respect. I sold a truck to a Pakistani government buyer. This guy was a cold fish to the extreme.' I excused myself to call my Mother, who lived with me. I told her I would be late, but there was soup for her if she got hungry. The Pakistani said," I thought Americans sent there old people to nursing homes". I replied that my family didn't and that my Mom was disabled and lived with me. This guy told me that his family had an aunt living with them. The guy became very friendly and we actually had a good conversation. I admire the Pakistanis and hold them in highest regard.
