I'm impressed! I didn't spot any toes missing!
The work is exceptional regarding the primitive conditions through!!!
Thumbs up!
Toes don't go missing, people do.
I think it's them safety sandals.. along with the face masks....@@kennysboat4432

They are wearing heavy duty sandals, safety first!
toes up lol
My heart is in my mouth when I see work like this being done in sandals. I was helping a work colleague lift a truck crankshaft from a bench into a cradle so it could be put in the cleaning bath. I was an apprentice and he was the mechanic and did not want to go to the other end of the workshop and get the mobile crane. It slipped from his hands and I let go and jumped back but he was not quick enough and it landed on his foot. The steel cap saved his toes but he still had broken bones that took months to heal with several operations needed. It was over a year before he could walk without pain.
This is nothing, the metal casting videos from these types of channels are something else. Sandals and zero eye wear. It's tragic to watch, to be honest, because you just know there are dozens or hundreds of serious injuries behind the scenes you're not seeing.
They are the famous safety sandals
Каждый раз, когда смотрю подобные ролики, меня поражает мастерство и профессионализм таких ребят. Без должного оборудования они умудряются проводить довольно таки сложные ремонты. Молодцы! Наилучшие пожелания из Беларуси!
Качество сам понимаешь таких работ

Они и коленвалы,и поршня отливают. На неделю хватит и то хорошо😅.
Это не ремонт
You do realize that the O.D is hard chrome plated. Any bending creates micro cracks all along the surface the seals ride on.
Also they’re pushing down directly on the shaft with the press ram….I’m sure there’s a nice big divot there now. Leaks, leaks and more leaks….this is a dumpster fire!
Ya the unpadded supports and unpadded press tool were pretty cringe.
@@luthmhor To me the entire shop is cringe considering the damage a grain of sand can do to that shaft and seals. 🤦🏻♂️
Wow, no PPE, hell, no shoes, I'm sure that eye they were beating is on spec, and the seals pinched while beating the rod into the cylinder with a sledge, are 100%! Wow! I bet they pull 5-10 miles a day on that hoist chain and no one seems to mind the wheel bearings in the trolly need some help. WOW! I'm totally confident that hydraulic press got them within in .005 LOL. And the. Micrometers looked dragged down a dirt road. I don't know how much they charge for that job, but its too much!
I mean, damn, this vid SCREAMS "third world s-hole"
Perhaps that's why it was rechromed. Did you watch the video?
Notice how they covered the eye with a red rag when they put it in the press. This was so you didn't notice they swapped the unit with a good one when it mysteriously changed color after becoming straight. Hey, with 3.4 million views and counting, they're getting paid for the content regardless of what they're actually accomplishing in the shop. Where's Funk FPV when we need him?!?
You are so right, good eye
Proof that if it doesn't fit you keep hitting it with a sledgehammer until it does...
We tried to straighten a hydraulic shaft to test a new press we got. We put enough pressure on it so that it was about straight when it broke. Two pieces flew around the shop like shrapnel. How the shaft got bent without it being bent back is something a metal expert would understand, but we could have been killed. That was the end of that. When you are stressing something with that much pressure you have to have all your ducks in a row. Ours were not even in the same pond.
But you weren't wearing sandals, that's the key.
For many years we had an bent ram spear kicking around our workshop. The guy who tried, unsuccessfully, to straighten it will never do anything ever again. That's right, it killed him 😢
A good hydraulic piston will not bend but break. I assume this one was cast and made three streets away from a mixture of a bicycle, a transformer and a rickshaw.
When metal bends due to being stressed, its characteristics change and in many cases it hardens; that is what you experienced. In this video that was not the cases. However, that doesn't men that all is well, no to the contrary. It's permanently damage. This hydraulic piston rod won't be able to carry the loads that it was designed for and therefore it's dangerous.
any metal that bends without breaking gets harder in the location of the bend, known as work-hardening. Bottom line: you can't bend it back with simple loading, if at all.
5:00 Да ладно! Оказывается у них в стране есть часовые индикаторы? Я всю жизнь думал, что они проволокой всегда биения измеряют 😮
Это элитная мастерская 😂
Добрый день. Да вы посмотрите у нас какие умельцы на Руси, свои доморощенные так сказать, те самые которые дырки в поршнях сверлят и на вкладышах дреммелем борозды нарезают, а еще норовят все медью измазать. Это я про д.Сережу Городецкого и Рамазана Акоева, эти гуру вообще все пальцем определяют на ощупь. Им измерительный инструмент в принципе не нужен. А всю техническую литературу по их мнению написали придурки инженеры, ни черта не понимающие в конструкции ДВС. А вы про Пакистан удивляетесь. Они от безысходности все это делают.

@@speed9070that's what idiots do

Cave dwellers 😅
I like how they use floor dirt to clean and lubricate sensitive machinery.
Fascinating! I know when they taped the ends with yellow tape that they were re-chroming the shaft. What was that process (other than 'electrolytic plating')? It looked like they were dipping it into rocks.
I think those are chunks of foam that just float on top to help with evaporation
Looks like giving a ice bath, hardens. Normally they use Nitrogen, elsewhere.
Everything in these shops comes out with a nice coating of break-in dirt to insure plenty of running clearance.
This isn’t their first rodeo. Great job!
Another good job from We Bodge It And Scarper brothers. Wouldn't like to be near that ram when it bends next time. 😢
A verdadeira arte da mecânica clássica. 👏👏👏👏🇧🇷🇧🇷🇧🇷🇧🇷
Que liquido fue sumergido y cuanto tiempo?
Thats what I love about these guys just do whatever they want and get away with it somehow working
I love the oversized wrench and Allen keys to make it work!
I've also seen it done with a dime or a nickel on smaller open end wrenches
Flogging wrenches
First class operation . Not even a slugging wrench that fits . Quality control . Appreciate the flash shield for welder in back ground .
At first i was wondering with that rench as well, especially if you have all this latches to just make one... on the other hand, they are not able to do any harm to nut that size anyways...
C'est incroyable de voir ce qu'il sont capables de faire ils sont très courageux avec peu de moyens beaucoup d'intelligence vraiment bravo
Amazing!! Ingenuity of that part of the world where people make do with tools they got and still achieve results like this? Simply Wow!!
Is that an old fan belt they are using as a lifting strap?
Aside from the cancer chrome dip, the finish on that rod was pretty nice. So good for them.

Not bad for Bronze Age
The cancer is an added bonus for them, they get to retire sooner !!
Well done,, You entertained me for 23.27 minutes 👍👍👍👍👍👍
second nickel coating to make it look as it was replaced, great
And polished it the wrong way 😂
Должен быть хром.
Качественно делают, даж часовой индикатор и микрометр есть. И хромирование сделали даже. Молодцы эти парни👍
Ага и микрометр свежий повереный. Не от деда достался. Кустарщина это всё.
@@user-wg9zb6bp4q какая разница какой микрометр. Они проверяли износ.
Всё что сделали чуваки в этом видео - заменили гнутый шток на новый. Видео монетизировано. И они по угару сняли кусок как они якобы выпрямили шток. Это всё хрень 😂 там идёт тупо склейка выпрямление гнутого штока - бац ровный шток, который они уже проверяют микрометром. Там даже видно, крепление гнутого штока измазано краской, а ровный уже без краски. Причём до ровного штока прессом не докасаются, а только делают вид. В любом случае даже если бы они как-то выпрямили шток, то ему один путь в помойку, т.к. он уже имеет неравномерные внутренние напряжения металла и опять согнется в том же месте при значительно меньших нагрузках, чем мог выдерживать новый негнутый шток. По сути кроме съёма гнутого и установки нового в этом видео всё остальное фэйк-сьемка для ютюба.
@@user-wo7sd4ju6r в 90х мы так же шток на кран правили и ничего работал не гнулся так что не пизди не надо
Скажите ,когда вал погружали в ванну я понял ,что это гальваника ? Хромирование?

I like how they clean the tube like a baby😊
Another reason to like YT. These guys bust their asses every day for thousands of years with no appreciation. Now, thanks to YT over 2 million people are watching them & giving them compliments. BTW, let's not forget to give them props for wearing sandals to work. I couldn't imagine dropping any of that stuff on my foot wearing steel-toed boots nevermind sandals.
All this in flip flops… much respect
No pude dejar de verlo hasta que terminó. No se porqué me llaman tanto la atención éste tipo de videos
Y me parece un buen ambiente laboral algo así como agradable.
You can endlessly watch the fire burn, the water flow and watch how others work.

Hey, Ahmed! Hit it harder! Harder!
Ouch, my toes! You dropped the damned thing on my toes!
Take your toes out of the way!
parabéns pelo vídeo, excelente!!!
How did you bend it?
Are they re-hardening the surface with liquid cyanide when they dip it into the tank?
Rechroming the surface - any chips, cracks or scratches in the chrome surface can cause hydraulic leaks and/or the entrance of foreign materials into the barrel which will destroy the wear bands and seals and can damage the inside of the barrel and further damage the rod..

Amazing work! Ive done this myself, but my shaft was bent just a little bit. It took a lot of pressure to bend it back, and it wasnt perfect but good enough and works well.
Its just amazing skills what theese guys do here
That’s what she said 😂😂😂😂
The original broke
13:40 it's on the floor
That’s enough about your sex life. What did you think of the video
@@FireBeamthat's what it looks like. That cylinder looked like it was bent too much to be usable. It snapped in two trying to straighten it out. That's why it's not shown. It goes from being bent to perfectly straight. Nothing in-between of them working it back into shape.
13:31
Не ну молодцы!!!! Интересно на сколько такого ремонта хватит!?. Раз согнуло и второй раз согнёт, при меньшем усилили.

i dont know about you guys safty gear, it is a bit lacking, but i love that purple caps, it gives some contrast 🙂
Good to see they have safety sandals
Yawn.
São raiz e não Nutella igual vc
Anybody else notice they switch rods in the press? The original bent rod was not the same as the straight one. Notice the different colors of paint on the eye end.
Good spotting.
oh. yes.
The bent rod was resting in the v blocks with no rags but the good rod had rags.
yeah! what about that?!
yes I noticed and made a comment. Good catch.
What did they dip it into?
Great video!
👍
The molecules are stretched on one side and compressed on the other. It would have to be reforged to fix it.
Exactly
The original broke
13:40 it's on the floor, the rust pattern is distinctive
Ничего В следующий раз
WOW!!!!!!!!! Good to see that you aren’t wasting that PhD in metallurgy and materials science. Personally, I missed the unit where they covered the impossibility of straightening a piece of steel. I’m so glad that you set the record straight (pun intended”. New textbooks will be written.
The more you clean it, the straighter it will be 👍👍👍👍👍
7:10 that's the same tape my ali express packager is using extensively.
Leather seals?
Insane
Please stop hitting the casting with the sledge hammer without a protective piece of wood. That sets up a future crack in that critical high stress area. Did they check/clean/measure the bore ?
who cares
@@Dec38105 Then don't bother to comment. Who cares.
@@lzed223 yes
Why measure ? Couple more cracks with the sledge hammer will do the shaft justice 🤣

Oh exactly my Persian? brother, and very well said. Good show.
these guys.
job security for sure with these repairs
I’m amazed they didn’t have a cylinder test bench. If anyone replies about the working conditions etc. They have lathes , a chrome tank etc you’d think they’d could put together a simple test bench with a electric pump to test hydraulic cylinders under pressure.
These guys work hard......💪
How long dose it take to rebuild one of those? Nice work. I learned a couple new tricks from this.
Oh I wouldn’t put your new tricks into practice.
As my Granddad used to say, you’re going to have to bend it to straighten it!
Wish they came this way 🇺🇸
oi,gostaria que vocês acompanhasse o equipamento até o destino final,ou seja sua montagem na máquina, e ele funcionando sem vazamentos.. obrigado,eu amo meu Brasil.
Porque havia de ter vazamento? O fluído hidráulico apenas trabalha no núcleo do atuador e o que o impede de vazar são aqueles grandes verdades na extremidade do veio empenado. Os outros verdades que são montados na cabeça apenas servem para impedir que entre demasiada sujidade no núcleo do atuador, e isso sim acontecerá certamente assim que o empeno começar a destruir a capacidade desses verdades.
OK now I understand why we have OSHA… 😂

It's not the same rod going in as came out. Look closely and you will see that. This is why we didn't see the "straighten" bit.
they even rechrome it good work
Согнутый потом под прессом под давлением равняет и место где прижимает останется мятина и ямки. Просто они ещё восстановили зеркальность и собрали. Это во время работы дасть о себе знать. Масла из выемки будет пропускать и сальники не поможет.
There not just mechanics but magicians too haha they completely changed the cylinder
The cylinder rod is straightened indeed, but it’s metal structure is demolished twice by the overload and the resetting. The metal’s memory will lead to a sudden fatigue’s breakdown.
I’m not sure, but I think that hole they put it in might have be an oil bath to heat the metal all the way thru to relieve the internal stresses. I seen hot oil baths used a lot when I was younger, but I think it is becoming a dying art these days
@Janderson-AppalachianCreative That was chrome plate, not a heat treat bath, which would be molten salt.
@@marshalltjones it’s so hard to tell what’s going on. They do things so different over there. I think it was India. But they make some amazing things with limited tools and equipment.
STILL VERY GOOD JOB. FOR WHAT THEY HAVE.
Sorry to break it to you, but the old rod broke
13:40 it's lying on the floor, distinctive paint/rust pattern by the eye
Rocking the safety sandals!
Did the colour of the yoke on that shaft change when it was placed in the press? It looked very different after it was "straightened"...
Different nut, different seals, different rod.
Yes it did right around the 4:37 mark.
The force required to bend a rod like in the first place, that is impressive.
Ignorance is a force to be reckoned with
They switched the rod out. Notice the orange paint on the bent one is now gone on the straight one.
13:40

If it is used locally after the repairs it should hold up if it is not perfect it may leak at top cap.

Yep. its crazyyyy, work with sandals... I wish him it would fall on his foot! Idiots...but he hask a mask...
What about the flat spots from being in that press?
if the hardness of the press axe is higher then the one they are straighting then a dent will happend , probebly a line since the contact type is between a circle and a surface .probebly
I take it that no one noticed that the rod that was “fixed” wasn’t the same one that went back into the cylinder as the one that came out. The nut they took off was different than the one they put back together. Also a different head gland. Also the rod eye is a different casting between the 2 cylinders. Yes I’ll admit that the work they are doing with primitive equipment is impressive the finished product isn’t actually what they advertise it to be.
I noticed the original broken in two when they brought the rod back over to assembly.
It’s good enough for what they’re going to use it for,wooden boat anchor
The video was done just after the 5 minute mark, when they took it from the press without showing even a single second of actual pressing.
It looks to me like a compilation of the process. I think each step is well represented in spite of the different parts involved. Kudos to the team for a comprehensive process with minimal equipment.
It's not an elaborate hoax as you are insinuating... Something got dismantled, something got straightened on the press ram and something got re-assembled... The video is just to show you what they do at these garages...
Excellent work 👍
I have straightened Two ram shafts, but did not pull them apart, that makes work, and the risk of more damage..
A drilling rig support ram, 40mm ram 1.2mtr shaft was easy and done in about an hour, then back onto the rig mast and working fine...
.
The second was a 60mm dia 1mtr stroke, was not removed, but was straightened useing
One of the other rams...
Care is needed to be sure to press on the high spot, otherwise you get a corkscrew in the shaft and you can never get that out...cheers from New Zealand
