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
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
The precision is amazing. Get a bigger sharpie.
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"
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.

That’s the supervisor, ensuring they only wear open toes, no eye protection and no mask. 😂😂
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.
I love useful people that have skills and work.
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
I love how they’re showcasing technology from 1890 in the USA
Порвало в месте предыдущей сварки миньонами)
What about the most important bit, the balance. Unless you balance the shaft again it will just break again.
Ensures job security...
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
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
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.
Молодцы ребята , очень уважаю!
Plenny o juice when welding 😁
Good way to loose a finger - removing the shavings by hand when the lathe is still turning.
Driver will get shaken, not stirred 😮
Muy buena relación a esa cardan, saludos desde oaxaca México gracias por compartir.
Señor usted es admirable un profesional total mis respetos y admiración lo felicito señor .saludos de argentina

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 🙂.
Уже ремонтировали сыромятиной - в этом месте и свернуло. Как всегда - из грвна и палок...
New full length tube would have been way better.
its so sad that they dont have precision tools, because it too expensive for them.
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…
Respect. I trust these guys.
It looks like someone added an extension to the shaft that was too thin.
A true artist.

Trop fort 👍🏼👍🏼👍🏼👍🏼
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.
Hooray for the pajamas and sandals guys.
How long before the lathe headstock bearings fail due to the welding?
Parabéns pelo seu trabalho 👏 👍 top 💖👏👏👏🤝🇧🇷🇧🇷🇧🇷🇧🇷🇮🇹🇧🇷🇮🇹
Отличный микрометр. И в целом операция - огонь.
Спасибо
Восторг! Несомненно, восторг!
Not much people can't do this..the best skill..❤

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.
Simply amazing.
Very nice work 👌👌👌👌👌
Enjoy your work. please stop putting words on the screen.
отнимите у них сварку и постройте уже школы...
Ремонт такой же уже был на этом кардане, и его свернуло, свернëт так же и этот ремонт 😀😀😀

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.
Após soldadura, é preciso calmar as tensões.
Now the truck has a vibrating seat for the driver😂
Выглядит надёжно
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 😂
The previous repair failed, so let’s try it again! Just buy a new shaft already.
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
Знаю где он в следующий раз отпилит-люнет сожрал половину толщины вала😅
Very nice work very well done you know what you doing very good job
Neat welding
Thanks
You'd think with all thier skills somebody could.make a table
Super Coole Typen ...Respekt

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)
я подумал что на превью две рыбы.
Ты правильно подумал
Спасибо
6:19 спасибо за подсказку. А я думал, как же он его в станок вставит?
Почему не используете 3-кулачковый патрон на токарный станке ?
Потому что они точат кривые вещи. В 3-х кулачковом их замахаешься выставлять.
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 🤔👍
Welded on both sides before. Heatzone in the mittlele did week the steal to rubber…… thats why it is so bendted
我相信在巴基斯坦，人的技術比機器校準更為可靠
I need some of these work pajamas.
I like the third world country dial indicator they use for setting up job
Thanks
Why wouldn't you measure the shaft size and cut both ends off weld the ends back on and balance it ? This is not repaired .. this is job security
5:00-5:30 anyone else have problem to listen to that hellish sounds? Like dog facing sprinklers, head shaking T_T
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

@@user-vj4th8ks1i Ты прав
Спасибо
@@restorationtoolshop Спорим, ты не понимаешь русский язык и даже не переводишь его.
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
Sooooo, no balancing just going to reinstall it? With instead of 2 now 3 weak points and again not balanced? Yeah right, feel sorry for whoever installs thar in their truck 😂😂😂
It's been repaired before, you can see the weld. They need to learn to NOT overload trucks....

انت على حق
شكرًا لك
Уже меняли в этом месте, по шву видно. Они понимают, что не на долго, но у них нет денег на новый.
OMG - oiling the guideways, lathes that weren't built in Halifax in 1922, tidy workshop, am overwhelmed.
Okay Thanks
Do these not need heat treated after welding?
yes .... repaired ... untested .. keep it out of my truck
ButI didn't see him align the U joints so that they're in phase...
Thanks 🙏
Restore master 👌👌👌🇮🇳🇮🇳🇮🇳🇮🇳
Thanks 🙏
Ain't no way that's road worthy😂
Now drive 100kmh and see how it wobbles
High skill amazing you profesional mr x
Thanks Sir
Fabulous work.....!!
Very much cycle of liking the work sir
very nice job, only one major mistake, not maintaining the parallelism of the universal joint that will be mounted on the splined shaft of this shaft ! 🙏😩
@@staszekboroski526 According to us, we have done very well
thank you
@@restorationtoolshop and the universal joints came out parallel ?
@@staszekboroski526 okay Thanks 🙏
you know if it keeps breaking over and over at the same spot, just buy a new one...
Doesn't that driveshaft need to be balanced.........
You are right sir
Thanks
Nice work bro 💯
Thanks Sir
OSHA approved footwear?
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
The reality of a mostly capitalist world is that the cheaper the relative cost of labour, the higher the manual skill base in the population. In the West this would not be repaired unless it was literally impossible to get from a stores somewhere because the cost would be prohibative.
My father was an apprentice mechanic in Europe in the 1930's when he was 14yr old, by 15yr old he was making his own white metal bearing for car engines. At 19 he was a chief aircraft mechanic with a team of 8 men working for him.
He could do this as shown on the video. But I lost those skills, as already by my 16th birthday when I started as a mechanic we replaced, we rarely repaired.
Will work just fine
Thanks Sir
@restorationtoolshop no problem u guys get it done thats all that matters
@@guypatts494 👍 okay
looks like its been fixed a few times, should have done it right the first time
normal que ça casse avec un tube, à la base c'est du tube plein..... vu la force de traction ça pete
