Another episode of "let's see how far we can overload our truck"
у меня каждый раз сердце замирает - когда они стружку руками снимают. я один раз видел, как паренек потрогал стружку, просто потрогал, реки кровищи на всю жизнь отучили.
их бережет Аллах! Allah hafis!
There is no way that that shaft will run true to the centrelineof the gearbox. They probably dont drive fast so the vibration wont be noticed. And itll get torn up with overloading anyway. Love to watch the work skills with what they have. Well done . Greetings from Australia
Austraila = Money
India = Broke
Thus the reapair !
Very interesting video on how to repair drive shafts - the one thing - you never see the drive shaft working - when they fix something I would like to see it working
Id like to see the truck ride 60mph with that drive shaft
Классно. После первого ремонта трубу смяло. Что мы делаем?? Чтоб клиент пришёл опять, вырезаем кусок такой же трубы и привариваем вместо старой и ремонт окончен
расслабься, это пакистан, какие у них еще варианты могут быть?
Гарантийный ремонт. Не иначе.
Первый раз варили встык. Второй раз варили со выставкой из обрезанного куска трубы.
Lol looks like a previous repair with sub par materials got twisted up like a pretzel and snapped off again in the same spot.
That's one way to provide yourself job security, I suppose lol.
Or, it could be a torque limiting safety feature, making it break in a predictable, easy to repair spot, in stead of screwing up the much more expensive gearbox or something.
Either way, it's brilliant.
Yep, its what you call a "mechanical fuse"
Don't forgett: they all are hard working man. They want to provide for their families. 👍
На самом деле он всё сделал правильно. Учитывая дикий перегруз такой кардан работает как плавкий предохранитель 😂 Уж лучше они кардан переварят, чем коробку или задний редуктор.
The men did not graduate from polytechnics, or even vocational schools, but you will admire the results of their work.
The precision is amazing. Get a bigger sharpie.
I repair drive shafts and I can say this shaft is not balanced or zeroed out. It will fail in the same way it failed from the previous repair.
No sir, earlier someone had installed a piece of indigenous pipe, so that pipe broke, now we have installed a imported pipe, now it will not break.
Thanks
That shaft will have so much vibration due to imbalance, guaranteed breakage.
@restorationtoolshop They did not use a dial indicator or a press to straighten after welding. You can't eyeball that stuff. It will fail.
EVEN IT WAS BALANCED DUE TO THE OVERLOADING OF THE TRUCKS IN THAT COUNTRY IT WILL FAIL.
@@kostasgrapatsas2074 okay thanks
I hope that arc welder ground lead is grounded to the piece he's welding and NOT clamped to the lathe. If the ground is clamped to the frame of the lathe all of the current is flowing through and arcing across the headstock bearings, that will damage the bearings.
So do you think this is the first time this guy did this type of work?
@@thepubliceye Why would you ask that? It's obvious that what he's doing is his job and he's doing the best with what he's got to work with. What I'm saying is a cautionary tale of why you should not ground the work through the body of an expensive lathe because the current flow will damage the bearings eventually via arc pitting between the balls/rollers and the race.
I understand that's one of those things that "Can Happen" but in reality seldom ever do. With roller bearings as tight as the lathe head it just doesn't happen.
In addition to the rollers, there are a lot of steel gears and even a sleeve bushing.
@@thepubliceye I don't want to come across as argumentative or mean any disrespect to you but what I described is a real thing that happens and I was there when it was happening.
Mechanics back in the 1980s working on Chrysler vehicles has a streak of bearing failures namely their front wheel bearings, we would just replace the bad bearings and the vehicle would return months later with the same problem. This happened frequently enough to where Chrysler engineers issued a TSB - Technical Service Bullitin when the figured out the cause of the premature bearing failure.
There was no internet back then and mechanics got their 'critical' repair info via the TSB and that one directed us to look for loose or missing body ground cables/wires and to fix that issue while replacing the bad bearing. Over a period of time that problem once corrected went away. Peace
@@slomotrainwreck I am aware of that
Good way to loose a finger - removing the shavings by hand when the lathe is still turning.
В каждом видео присутствует грустный мужчина, который просто стоит опершись о колонну...😀
это инженер по технике безопасности - он проверяет чтобы все были одеты в ночнушку и туфли с острым носом ахахахахаха
That’s the supervisor, ensuring they only wear open toes, no eye protection and no mask. 😂😂
Impressive and outstanding...! The lathe operator is exceptional....!
I hate to think what condition the lathe bearings are now in after being used as a conductor for the welding!!
Was thinking that exact thought. On their new lathe too
Well, you don't know where they put the ground . Perhaps on the drawbar/colet chuck holder, they are solidary to the spindle
Всем подшипникам там уже давно хана. Поменяют😂
Карданный вал, обязательно нужно балансировать.
Надо быть отчаянным, чтобы голой рукой сбивать стружку с вращающейся детали
Или безмозглым😂
New full length tube would have been way better.
Driver will get shaken, not stirred 😮
Порвало в месте предыдущей сварки миньонами)
The way these trucks are so often overloaded and abused makes me realize why they just continue to replace with crummy stuff. It isn't really worth the cost and shipping for new replacement.
My hat is off to these guys who create some pretty amazing stuff with old equipment. They make it work with what they have to work with. No waiting around for someone in a government agency to "save them".
I'm wishing I was well off enough to send a c-111 full of safety gear and boots to these guys though 🙂.
This is the cleanest shop I've seen in a long time.
Thank you sir, you like our shop
Como serán las otras, si esta parece un basurero, taller horrible
All things relative this is a clean shop and some of the cleanest lathes also. That said I see shafts going into the lathe and not once have I seen anything wiped of floor sand. However if the a market accepts the results I guess it’s good enough, who am I to say.
Muy buena relación a esa cardan, saludos desde oaxaca México gracias por compartir.
It looks like someone added an extension to the shaft that was too thin.
Why not cut the ends off and replace the whole tube?
That's what we do in the USA
@@TOONMAN200because we do it right the first time. I guess its cheaper to use just a small section of pipe than an entire length.
The guy needed the extra money to buy more doo dads!
First of all in the USA I never seen a drive shaft twisted that bad.@@John_Redcorn_
You bill the customer for a complete length, you cut off only what you need and repair the gap. Extra profit, plus more shaft for the next job…
its so sad that they dont have precision tools, because it too expensive for them.
Уже ремонтировали сыромятиной - в этом месте и свернуло. Как всегда - из грвна и палок...
Why did they just not cut joints off each end and replace with new length of tube
They snapped it before looking at that double weld. The breakage is in the heat affected zone of the previous weld also. I think they need to take it easy deploying the NOS with weak drive shafts. 🤣
По этим видео можно собрать свою Ладу гранту
I built Rockwell drive shaft and Spicer drive shafts at Mack Trucks manufacture plant and at freightliner dealer ship and thats not how we repaired or built them
Biggest error is splicing the tube
If you noticed where it was twisted it had already been spliced next there is a indexing arrow on the stub that aligns with the slip tube that aligns with the yoke at the other end before welding ( the yokes will never align properly) true hacks that dont know what they are doing
No. First we have leveled the line of both the crosses and then we have done welding
thank you
True hacks? That’s a little harsh. These guys are doing the best they can with limited resources. Give them a break.
What about the most important bit, the balance. Unless you balance the shaft again it will just break again.
Ensures job security...
Señor usted es admirable un profesional total mis respetos y admiración lo felicito señor .saludos de argentina
I love useful people that have skills and work.
Молодцы ребята , очень уважаю!
La pregunta que siempre me hago es: ¿Por que nunca limpian nada?
A true artist.

Mashallah zabardast good work
Not much people can't do this..the best skill..❤
That dude who broke that drive shaft must have not been granny shifting double clutching as you should
I have seen other channels do similar repairs with lots of high tech equipment, and the result is no better than this. Very enjoyable to watch your skill and ingenuity
Thank you very much
Shops with High Tech equipment wont repair drive shafts like that cause its just cheaper to replace.
@@The_Black_Sheep95 In Pakistan replacing is almost always not an option
@@The_Black_Sheep95 Thanks
@@The_Black_Sheep95 True but it's hard to grasp just how cheap labor is in Pakistan. It's so much less expensive to repair there. It used to be that way in the US also.
I once did that to a drive shaft of a semi in trucking school. We were practicing backing up trailer and I was in reverse gear, as we were backing up my foot slip letting go of the clutch and instinctively press on the break with the other foot and it caused the drive shaft to twist and drop to the ground, look pretty much like this one.
как вообще можно сломать кардан? видно что это не первый ремонт, токарь молодец знает дело своё
Respect. I trust these guys.
How long before the lathe headstock bearings fail due to the welding?
Eu não teria coragem de viajar em um caminhão ou carro com esse tipo de reparo. Deus me livre disso.
Made in Индия или Пакистан, ой ой, с токарки можно в космос😮

Спасибо
Восторг! Несомненно, восторг!
Parabéns pelo seu trabalho 👏 👍 top 💖👏👏👏🤝🇧🇷🇧🇷🇧🇷🇧🇷🇮🇹🇧🇷🇮🇹
Trop fort 👍🏼👍🏼👍🏼👍🏼
Excelente profissional.
Enjoy your work. please stop putting words on the screen.
Após soldadura, é preciso calmar as tensões.
Simply amazing.
Ремонт такой же уже был на этом кардане, и его свернуло, свернëт так же и этот ремонт 😀😀😀
А ТЕБЕ НЕ ПОХЕР

ты если руку сломаеш к врачу пойдеш и будеш лечиться хотя шанс перелома в дальнейшем все равно останется
As always great video. It's interesting to watch you guys repair stuff instead of sending it to the junk pile like most places these days. I'm sure the customer was happy to be back on the road asap. 👍
Thank you very much sir for liking our ka
I love how they’re showcasing technology from 1890 in the USA
6:19 спасибо за подсказку. А я думал, как же он его в станок вставит?
Hooray for the pajamas and sandals guys.
عمود الدوران او مايسمى بالكردان مصنوع من الحديد الصلب. وهنا يتم تلحيمه وتوصيله بقطع حديد عادي غير معالج مما يتسبب في كسره مرة اخرى
انت على حق
شكرًا لك
That repaired drive shaft is probably more true than any new drive shaft built in the states !
Yeah, I think that’s a bit of a stretch of the imagination.😂
@@DimSimSam I don’t think that’s the first time they
repaired that driveshaft in the same place . LoL 😂
Welded on both sides before. Heatzone in the mittlele did week the steal to rubber…… thats why it is so bendted
Might this failure have something to do with serious and relentless overloading? That’s also why they’re constantly repairing cracked springs, axle/diff housings and failed trans-axles. But they do what they have to with what they have in often clever ways.
Он же уже ремонтированный...🤣
unsurprisingly, the shaft twisted and broke where someone had already changed part of the tube (and put a veryyyy thin piece compared to the original)
You'd think with all thier skills somebody could.make a table
ButI didn't see him align the U joints so that they're in phase...
Thanks 🙏
Why don't they have a decent chuck?
отнимите у них сварку и постройте уже школы...
我相信在巴基斯坦，人的技術比機器校準更為可靠
Plenny o juice when welding 😁
OMG - oiling the guideways, lathes that weren't built in Halifax in 1922, tidy workshop, am overwhelmed.
Okay Thanks
Yo usaría un tubo entero no soldado , igual el cardan no hace fuerza solo transmite tracción a las ruedas traseras
Just a thought… What would happen if they made it mandatory for their trucks to go over a weigh bridge to ensure they’re not exceeding the GVM of that vehicle.
Can’t see that happening though, but it might prevent some of the catastrophic mechanical failures such as the one shown.
Just saying 🤔👍
Super Coole Typen ...Respekt
Выглядит надёжно
Знаю где он в следующий раз отпилит-люнет сожрал половину толщины вала😅
The weld is fine. But, I thought he would turn down the high spots in the weld while it was chucked up in the lathe.
You are right sir
Thanks
5:00-5:30 anyone else have problem to listen to that hellish sounds? Like dog facing sprinklers, head shaking T_T
very nice work
Thanks 🙏
Now drive 100kmh and see how it wobbles
Do these not need heat treated after welding?
Could have reached inside the six inch piece of pipe to weld like you did with the inside sleeve...?
No. One piece is welded from both sides inside and out and one is welded from outside only
Thanks
you know if it keeps breaking over and over at the same spot, just buy a new one...
Now the truck has a vibrating seat for the driver😂
Уже меняли в этом месте, по шву видно. Они понимают, что не на долго, но у них нет денег на новый.
я подумал что на превью две рыбы.
Ты правильно подумал
Спасибо
not even watch the whole yet and can see the this “repair” has been done before and broke in the same spot the previous weld look strong.however the base metal of the repaired tube used is to soft that why it twisted.
You are correct, but it is not the welding that is broken, the pipe is broken
thank you
Mechanics fix the similar truck problem always, because drivers abuse their truck, overloading.
You are right Thanks
No they don’t there is no mechanic that will fix a drive shaft like this! It wont hold! Semi mechanics just replace the drive shaft with a new one! These need too be precisely balance or they break again or tear up the transmission
Very nice work 👌👌👌👌👌
Ain't no way that's road worthy😂
We use a dial he uses a steel rod !
You are Right Thanks
Почему не используете 3-кулачковый патрон на токарный станке ?
Потому что они точат кривые вещи. В 3-х кулачковом их замахаешься выставлять.
Don't you just LOVE the sound of chatter coming from a dull tool?
The smoke is also a nice touch.
yes .... repaired ... untested .. keep it out of my truck
Without doubt some of the best uploads on youtube , always a pleasure to watch , these "back yard " engineers have serious skills .
You are right they work for big vehicles
thank you
Serios problemas con la seguridad personal
Obviously repaired before, and that didn't go well^^
Doesn't that driveshaft need to be balanced.........
You are right sir
Thanks
Neat welding
Thanks
No 3 jaw chuck was hurt during the making of this video….
No hurt, thank you sir
God job!
Hopefully this time it will run next 5 miles without breaking apart.
Thanks Sir
It won't even make it out of the driveway.
@@markniilo Luckily for the owners all "repairs" included backlight-warranty.
So most trucks never left these shops again.
It will work , most twisted drive shafts happen when forcing the tractor under a trailer that is heavy and too low . Or overloaded truck in a ditch and trying to just drive out . With normal use it will hold . Worked at trucking company 10 years and saw a few .
@@txrick4879 Impossible, working 10 years in Pakistan's trucking company, because until a few years ago, trucks were completely unknown in Pakistan and for all transportings donkey-carts were used.
Maybe you're confusing it with a broken leg on a overloaded donkey?
