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

toes up lol
Это волшебные сандали , без них не чего не получится.

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!

Это не ремонт
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.
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...
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?
These videos always amaze me. I have to say they look like the most comfortable safety shoes I've ever seen. 👍

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.
Que liquido fue sumergido y cuanto tiempo?
I like how they use floor dirt to clean and lubricate sensitive machinery.

Thats what I love about these guys just do whatever they want and get away with it somehow working
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
...
Is that an old fan belt they are using as a lifting strap?
How long has it been since they changed the oil in those clothes?
How did you bend it?
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...
Another good job from We Bodge It And Scarper brothers. Wouldn't like to be near that ram when it bends next time. 😢
Well done,, You entertained me for 23.27 minutes 👍👍👍👍👍👍
What did they dip it into?
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

Everything in these shops comes out with a nice coating of break-in dirt to insure plenty of running clearance.
رغم أنه عمل رائع و جبار واحي هؤلاء الرجال على ذلك ، لكن لا اعتقد أن العملية ستنجح إلى حد كبير ،لأن مثل هذه القطع التي تعمل بجهد أكبر إن تعرضت لصدمة بالغة لن تعود مثلما كانت ابدا وستعيد الكرة ثانية ! على كل حال كما يقول المثل الواشك على السقوط يمسك في الأشواك
Oh exactly my Persian? brother, and very well said. Good show.
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..

What’s more amazing to me is that most of these guys managed to keep all ten toes after many years of doing this kind of work 🤭🤷🏻
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 !!
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.
This isn’t their first rodeo. Great job!

Hey, Ahmed! Hit it harder! Harder!
Ouch, my toes! You dropped the damned thing on my toes!
Take your toes out of the way!
It seems to me it should have been heat treated to prevent this from happening again. It has already been weakened in the spot that it was bent, I have worked with large valves and steel in the ship yards...
Wouldn't worry about the old one, it broke
13:40 lying on the floor
@marionboren5787 At 4:37 on the eye side, there is yellow paint on shaft, they apply pressure and then in the next shot, there is no paint on the shaft near the eye, but as they move it, you can see a broken ram on the ground with paint on the shaft that looks an awful lot like the original one.
It amazes me to see these men working in a fabrication environment in sandals.
Yep. its crazyyyy, work with sandals... I wish him it would fall on his foot! Idiots...but he hask a mask...
second nickel coating to make it look as it was replaced, great
And polished it the wrong way 😂
Должен быть хром.
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 🤣
@@williamsulewski4240 yawn
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.
Great safety footwear, swapped ?
If you ever watch crane accidents, this is where they come. Live to tip over another day
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.
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.
Are they steel toe capped sandals
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
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.
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.
When Churka works, it’s so nice to watch!

How are foot related injuries over there? Are the men super aware of their feet and everything around them or do 30% of them have deformed feet or missing toes?
I have watched several videos of Packastanies repairing hydraulic cylinders and this is by far the best repair I have seen. I would have these men repair my cylinders any day.
I bet you'd love these guys oiling up your cylinder 😂😂
Your curved cylinder can never be straightened.. jus like dog's tail.😂😂
OK now I understand why we have OSHA… 😂
Cos ya'all are on coke, crack, weed meth or booze?
Amazing work 👏👏❤😊😊
Why do they cut the video during the first drop of that hidraulic jack? After that…that rod look different
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
👉👇👇👈👈👈👈👈👈👈👈👈
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...
Aqui no Brasil e difícil desempenar uma haste dessa geralmente elas partem ou se quebram parabéns usem um compressor de ar

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.
Let .....me........guess........ they overloaded like they do everything else ?
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.
If it is used locally after the repairs it should hold up if it is not perfect it may leak at top cap.
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
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.
Amazing!! Ingenuity of that part of the world where people make do with tools they got and still achieve results like this? Simply Wow!!
What was that tank they dipped it in with the yellow tape? I want to think its a chrome tank but I wasn't seeing any power supply and it was far to shiny when it came out for it to have been freshly chromed.
Plating of some sort
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.
Все понятно - но что это за вертикальная ванна с какими то щепками ? После такой рихтовке на прессе разве хром на штоке не разрушен ?

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
7:10 that's the same tape my ali express packager is using extensively.
All this in flip flops… much respect
Why they didn't examine internal surface of cylinder? It may be heavily scratched by piston, so, the jack will not hold the load.
It should last all of 5 minutes with a few leaks here & there as well.
These guys work hard......💪
If I didn't know any better, I would say this piston shaft was substituted during the process. Seems the clevis (eye at the top of the piston rod) turned different while it was in the press. And, the seal gland (piston cylinder screw on cap) was cracked and then it appeared all well! One more thing: not wise to smack the end of the piston shaft with a sledge hammer. You will damage the clevis opening. There are more professional ways to get the piston back into the cylinder.
Well spotted
Yep it was switched.
Just mad these guys know how to keep shit running and all you do is replace
that's the north American way. Throw parts at things and hope for the best.
@@graysonparks9703 Look at the paint on the shaft near the eye prior to 4:37 it is different from the paint on the shaft after that point. Also, there is a broken shaft on the ground that has the same paint pattern as the original shaft.
Notwithstanding this appears to be R and R instead of straightening, the remarkable work these guys do with a minimum of equipment and technology and maximum ingenuity and elbow grease is amazing

What is the run out tolerance? .005?
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.
