Hydraulic Cylinder Rod is Stuck and Bend Due to the Hitting of Heavy Stone | Check How it's repaired
ฝัง

- I explain how to check the straightness of a hydraulic cylinder rod and calculate allowable run-out. This is an essential task when repairing any hydraulic cylinder, because if a bent rod gets put back in, the life of the rod seal(s) is compromised and the cost of the repair largely wasted.
I also explain that bent rods can, in many cases, be successfully straightened and re-used. Provided they can be straightened to within the allowable tolerance. One of our members who works for a cylinder repair company, sent me his counter position on this:
"In our experience, 'straightened' rods are never really straight. They almost always have an S curve in them after straightening has been attempted - because they do not re-bend in the same place they originally bent. Using these bent 'straightened' rods greatly compromises the column strength of the cylinder, and is unsafe for a heavily loaded cylinder. It also wears unevenly on the gland and rod bearing, and frequently doesn't seal well. For these reasons, we never try to straighten or reuse a bent rod. I would urge you to rethink your advice on straightening hydraulic cylinder rods."
I respect Don's viewpoint. I just happen NOT to agree with it.
Before I explain why, let's clarify what I mean when I say "bent" and "straight". I'm not talking about bent like your elbow. I'm talking about a deflection that's only detectable with a dial gauge. In this context, a rod is "bent" when it's run-out is outside allowable tolerance, and "straight" when within allowable tolerance.
Now, here's why I don't agree with Don. Many years ago, I worked for a company which repaired a lot of cylinders off mining-size hydraulic excavators - 250 tons operating weight and above. So we're talking about rod diameters of 200 millimeters (8") and up. Many of these rods were induction-hardened. And a lot of them would come to us "bent" as defined above.
At the time, the replacement cost of the smallest of these rods was around $10,000. So if we had refused to straighten these rods, we would have made a heap of money - right up until the point when our customers woke up and we lost all this work to our competitors.
Back then, we gave a 6,000 hour warranty on all our rebuilds. And the expectation of any rod we straightened to our satisfaction, was that we wouldn't see it again for at least 10,000 hours.
Notice too, I said many of these rods were induction hardened. In the interest of full disclosure, I have heard third or fourth-hand accounts of the induction-hardened layer violently shattering while straightening was been attempted. In my direct experience of straightening induction-hardened rods, I've never known this to happen. Nor have I ever heard a first or second-hand account of this happening from a reliable source.
My suspicion about this is, when it has occurred, the rod being straightened was bent like your elbow, rather than "bent" as I have defined it above. Either way, the benefit of doubt, and therefore the possibility of this happening, must be conceded. You have been warned.

Must be a union shop.
A series problem is that when a rod is bent like that, it has crossed it's elastic limit at that specific zone and it can no longer withstand heavy loads intended for it. And It will get even worse. Just straightening it up won't solve the problem.

Качественный ремонт в таких условиях не сделать, если там только нет чудо-мастеров, которые обладают необходимым парком оборудования для такого ремонта (судя по тому, как доставали шток из гидроцилиндра, с мастерами и оборудованием там все не совсем хорошо).

Poor Curtis lol
Will be amazed if it worked .I used to work making hydraulic rams and the tolerances are around 10000th of an inch....
They'll make it work
Yeah, that was kind of what I was thinking. That rod will never be true again. Admittedly, most of the cylinders I work with are nowhere near the scale of this one. Makes me wonder what kind of seal it uses and how rapidly the misalignment will eat it.
Hey Kris look around where these mechanics are and welders and everyone else that works hard there. For one the way they handle everything to there best ability and guess what it comes out very strong and dependable.
This shows that adjusting the pressure relief valve can save you a lot of work on unnecessary damages of hydraulic equipement :)
he he..I dont think they know what a pressure relief valve mean.
Probably turned it to 11 so they could lift more dirt lol.@@orionwolf530
People making fun of these guys probably never even changed a car tire. They have minimal resources and got the job done, you think if they can afford a new rod they wouldn't have thought of that?
I don’t know where to start. Annealing the rod in the fire will destroy its strength. The chrome platting is damaged by the bend and will flake off in short order. In the straightening process they used a flat rough metal plate, nothing to say the v block on the bottom, there is more scars on that rod than you can imagine. This hydraulic cylinder is going to leak and the first hard push and the rod is going to bow due to being annealed. As far as the rod being straight, well, I’ll leave that up to you.
indeed...my dear friend....that's why the quality is so different...
Keep in mind that the cost of the part is probably 10 yrs wages for the avg worker there. A $10,000 (USD) part is about 9-12 yrs salary, the average earnings of those sandal-wearing folks is about $700/yr
They need to keep on going and preserve parts to make a living. Yes it isnt 100% reconditioned or perfect, but it will make do for the time being
Naaaa they dont use it.....they fix it and ship it to USA.
@@FjordTrotter and once the spool is jammed when the chrome flakes off that's about another 40 years wages its a shite repair no matter how you dress it up
Bonsai , and what do you suggest , buy a new one , Never expect the entire world should think the American Way 🤣 there’s more in the world than the buying spree of capitalism 💸 , if it can be fixed ,we’ll definitely fix it ,
That chrome plating is pretty important, looks like they did a number on it. Not to mention ruining any prior heat treatment by putting the part in fire. I’m sure it will still work, just not very well or for very long.
Heating like they did relieves the stress of the bend..
Once straightened which we will never know since the video isnt complete, is to heat treat the shaft again to it's original molecular structure set by the manufacturer..
Then polish the shaft hopefully the chrome finish isnt that bad..
Rod steel are 1040 and 1045 and by far the most used but there are some of 4140 rods as well...

Metal has memory. Once the grain flow has been disrupted, that’s forever. Incredible repair with available resources.
@@LuggageStardate I run a Hydraulic repair workshop, the rod is induction hardened hard chrome bar and heating it to straighten it ruins the hardness.it will be far weaker when put back on the excavator and prone to rock and stone impact damage ,unless it goes through an induction hardening process again it will fail sooner or later usually destroying the ram tube as well ,replacing the rod is the only correct repair.
I don't think this is a major problem among other they have.
This got them out of a jam, plain and simple.
@ james sands they are putting strength back in the metal by stamping it with the press it might be stronger than it was from the factory.
@@zvotaisvfi8678 they aren't stamping it or reforging it they are just straightening it .it will be far weaker without correct induction heat treatment.
I've straightened rams before, when a new one wasn't available quickly enough and they've been run every day for years, cancelled the order for a new one. Seals will tolerate a little bit of wobble, maybe not as long as a dead straight rod but plenty good enough for these guys. Not everybody can afford to just buy a new one. I've done some very sketchy repairs to get me going, then bought the new part but kept it until the repair fails and incredibly, it never fails.
I love the OSHA approved safety sandals
OSHA has Jurisdiction there?
We are 240 million living in Pakistan without safety. 1 replaced by 100
That's funny! you talk about osha yet these men are getting stuff done fast without all the red tape and hurdles. if you depend on osha to keep you safe then you're the problem. safety is within us all. we don't need a government agency to dictate that to us, yet ya'll seem to think osha is God to the workforce. more power to these men that worked together to get that ram out. teamwork!

@@rickwilliams4342 Это инструментальный калиброванный пруток!)))
This is a temporary solution at best when a machine "must" go . Hydraulic cylinder rods have to be perfectly straight else the seal will leak . The "straightening" process here did not truly straighten the shaft , only turning on a lathe , which is tricky , at the end will do that after pit repair , the chrome is severely compromised . It should be rechromed ! The strength of the shaft also has been compromised , to what degree ? The first heavy load will tell !

hauptsache keine ahnung von der materie.
For those who comment on the reconditioning quality - you need to consider the costs involved.
The average wage for a worker there is less than $1000 USD / yr. So a full replacement cylinder is about 9-12 years wages. In developed nations, think of it as a $250,000 job just to replace a part for the machine. How would you go about it? This is their only choice for survival - and it does work, albeit not perfectly.
Exactly.
In Canada those guys would make 30 to $50 or maybe even 60per dollars per hour.
That thing would have been scrapped here and a new one just simply ordered and then installed.
So good point.
Yes. I agree. That's not their fault. They are doing their best in their condition.

Surprisingly they know what they are doing. He even flipped the aken around once it was loose to back it out all the way.

At the end, they started to figure out something, although it's majorly sketchy. Before that, they were trying to find a clue, or rent one. At the beginning, they were so lost that Lassie couldn't find them if they had bacon in their pockets. I do think if you beat on it with that hammer for long enough, it would have straightened a few millimeters...

it's going to end up costing way more when it dies a new death in a day or so. Hydraulic pressure is not to be played with.
I had a boulder fall on a heavy stabilizer hydraulic cylinder just like that and bend the rod. I straightened it by very slowly working it over a period of hot days and keeping it max lobbed. It worked and is fine now 15 years later.

Совершенно верно. В наше время, инспектор по безопасности, это человек который лишает тебя заработка.
Hats off to them for the amount of effort and dedication to the task of trying to salvage it.
That being said, it was quite a lot of time and effort troubleshooting when they should have just undid the couplings and use either the vehicles or the excavator far earlier. Having the dude hit it with a hammer hoping it would magically straighten or pull it out, 3 or 4 different attempts at that.
As for the end result, it will probably work, just not for long; which to be fair, might be all they needed in this situation. Sometimes getting a replacement and legit repair just takes too long and time can be essential.
Also funny seeing the comments full of people pretending to understand metallurgy.
I don't know much about metalurgy but I'm quite sure the fire was to temper or soften the previously hardened steel. So they now have a softer ram to work with. The bright side of it is that it will be easier to restraighten the next time(s) it bends.😂
They deserve the $1 a day for that quality work
They do the best they can with what they have.
$1 per day would likely be a significant raise.

Limited resources but they do a repair that will last for a while. Hats off to them.
in addition to that, they do it in less than 2 weeks and dont need 600 pages of paperwork.
Looking past the heating of the rod destroying the temper and using a press to straighten the rod resulting in fractured chrome plating, that rod is visibly not straight. As little as .005 of an inch will let it puke oil like a bulimic after a feast. The next time the rod will not bend, it will fracture at the most severe part of the original bend.
There is probably three or four ways to do something the correct way, and a few million ways to do it the wrong way.
Absolutely, they don't show it in operation holding pressure...
Condivido tutto !
I had one of those crooked rods. Feels hard and straight, like it could handle it. But then I pushed it in and out a couple times too many, and you know what? It really couldn't hold pressure! It blew that hot liquid all over the place. Everyone was covered! Darn difficult to clean it off too. Sticky as frig.
And they picked every wrong way they could, not to mention just how dangerously they did them! If you overstress a chain and it snaps then you have lots of shrapnel flying all ways going through anything softer (human skin) than it!

It's hard to see, how these guys put all their skills and knowledge together to fix this stem of the hydraulic cylinder. Do they know, how they change the metallurgical structure and mechanical properties of this part? Overbending, heat treatment and a rough treatment of the hardened surface will result in an mechanical failure, when they reinstalled the parts and get it working under full pressure.
Great skills that they managed to fix the stem, but less knowledge how it reacts under their treatment.

Amazing that you were able to straighten that rod out with a bit of ole fire and a press. I highly doubt that it will work very well but nevertheless pretty impressive with primative tools. I do however question the strength of that rod after you heated it, you just weakened its strength. The chrome is liable to crack and flake off. Don't know how much oil this rod will be able to hold with all the pits and scratches. I use to build these things from scratch and weld the eyes on the rods. When I was a welder fitter. Where I am they wouldn't even attempt that they would simply replace it.

Мы делали шток диаметром 70мм. Получилось почти идеально ровно. Помимо того нам просверли почти во всю длинну штока отверстие точно по толшине прутка со стороны поршня. С другой стороны сверлили маленькое отверстие примерно 5мм для выхода воздуха. Потом грели шток но без фанатизма для расширения отверстия под пруток. Пруток держали в морозильной камере. Когда запресовали пруток в отверстие и шток остыл получилось как одно целое. Пруток использовали от ломика который был сделан из торсиона примерно 20мм.

This really depends on where you are in the world. In this case, a repair is way cheaper than a replacement. In other placed maybe a replacement is way cheaper in terms of time and money.
This thing just has to work, it doesnt matter how good or how long, just that it works. A hydraulic shaft with a bend this bad goes directly into trash since it can never regain its full strength. It will work, just not as good or as long as it could. At one point this could become a literal bomb.

I love how they spent all that time and energy beating on it when they had an excavator right there!
I think that's a crew of people that pretty much r & d methods for salvaging. And they are wanting to start out looking at the least amount of resources necessary to get any given type of thing done. Seems like it.
Прецизионная точность, ремонт на века.
Первое слово в точку,остальное хуйня в мульду!

Heavy machinery and no boots, open toes, that’s skill!
For what these guys have to work with they do very well.
Покажите работу цилиндра после этого! 🤔
А все))) некому уже показывать... Упокой Господи души рабов твоих....
Шутка.... Но все понимают, что этим все грозит....
Нормально будет работать, ведро отработки на смену хватит
Если полнагрузки то дофига будет работать
Он на масле уже не будет работать, только на солидоле))
если бы не работал - не чинили бы ))
I wonder how much more likely the piece will be to bend when it goes back into service?
how chrome bar do that
Intră în funcțiune la fier vechi și apoi la conbinatul siderurgic la topit
I admire their enthusiasm, 0 waste everything goes to the treatment of repair. And with us everything is thrown away because why fix something better, buy new and litter the planet
It looks ok on the surface, but that rod needs to be tempered again and nitro oxide plated. It will bend easily again if kept that way.
Yep, just replace.
@@Robert-cu9bm all fine unless the nearest replacement part is on the other side of the world or so obsolete as to be completely unavailable. And wouldn't you want to harden it, not temper it ?
Still the artist bunch could probably make one from scratch. Looks like this was shot in Pakistan. Some of those guys are amazing - make functional automatic weapons using a file and a hacksaw.
These guys are wearing sandals whilst working heavy machinery 😂 does it look like these 3rd world cretins give a f**k if it were to collapse and kill someone in the very near future 🧐 these people are a shamble doing a job that's equally a shamble. It's no wonder they still shit into their own hands 😂😂
Will you pay for that?
@@Robert-cu9bm will you pay for that?
That's going to be a precision fit. Not to mention the hardening after being heated
The heat took the hardness out
They don’t realize that that 4 door toyota pickup in the backround is worth a gold mine in America right now 😂
Thats the silly thing
For us in Australia as well that's a $3k clapped out old hilux but you want an American truck like an f250, anything newer than 2010 is going to get well over 60k up to 180k for a new ram 2500
I like how they simply refuse to give up until they've found a way to get those two pieces apart. Sometimes it really is a case of mind over matter.
They wasted their whole day moving broken shit around tho lol
They are really cool
@@joshdeane8299 Yeah, in a western type economy, where time is money, you'd be absolutely right. There it would be cheaper to scrap the original part and get a new one. But this is India or maybe Pakistan where time is valued differently and parts for vehicles are sometimes more expensive than the week's wages of 20 car mechanics.
Nothing in these countries is ever thrown away, everything is repaired, sometimes 4 or 5 times before it is considered scrap.
@@mikethespike7579 Meh, I've seen worse in the US, waiting the whole day for an "expert" to come do it or waiting foor a replacement, or whatever. They don't wait for anybody or anything, they'll repair that thing with what men they have and what tools they have.
@@rap3208 Desperation is a great motivator.
Steel can't be straightened on a flat table. You have to overbend or heat forge.
I’ve seen hydraulic cylinder rods break or have a slight bend but never one like that and I was a diesel mechanic and worked on heavy equipment as well as trucks.
That thing's friggin geeked 😂😂
But you people forget where's that made. It Chinese made. We use item of china's made from kitchen to airplane.
Наверно была авария, вот его и согнуло.
@@infotration2225 it's made of chinesium, that metal is about as hard as lead on summer day.
@@TheNefastor but still not hard as the Japanese made.
glad that nobody got killed fixing this one.......Success : )
Отпуск закалённой стали в костре это очень мудро. После высокой нагрузки шток опять таким же станет.
Скорее всего заказали новый, а пока он в пути хватит поработать на небольших нагрузках и этим.
@@user-cp1bb6le1g ага, заказали новый, в соседнем гараже.
Если он не лопнул при таком изгибе, то скорее всего это уже восстановленный шток, только в соседнем селе.
Шток не калёный, там поверхностная цементация, я на токарном станке их точил, прекрасно обрабатывается.
еще раз нагреют и закалят в чем проблемы, а то что и кривой немного шток работает по себе знаю, просто манжеты чаще придется менять..
What a waste that cylinder will only wear out seals and ultimately fail when it takes a load .
If the chrome is not pitted or the walls of the cylinder are not scratched it will work i am in texas with car haulers and i have some repaired cylinders that the seals last just as long a cylinder that hasn’t been bent and straighten
They are also in a country and area where they possibly can’t get a replacement. So a job like that to just get the work done will work.
Con los pocos medios de los que disponen, impresiona lo que consiguen
Herramientas medievales . Talento tienen de sobra . Con herramientas de primer mundo te arreglan todo
Real engineers, no BS or whatsoever, hard work, amazing results.
You can straighten a cylinder rod but in this case the inside of the cylinder was scratch and that they can not fix it. We had in our shop an old 12 ton crane which tipped over. Normaly should be scrapped but that was in 2007 Romania. We inspect the inside of the telescoping cylinder , straighten the rod. Welded some spots with MAG where rod was pinched. A bushing was made so we can see where is not round. Then a lot of grinding and polishing. New seals and ready to go. I worked before that 6 years for a german company where a job like this was considered an abomination. I do not know how much it last but was a 5-6meter cylinder. In six months there I learned a lot because there they were like Nike, just do it. We had lathes milling machines, rectifing machine, MIG-MAG welders , 40 tone press but some things we did make me cringed.
I am relieved to see that he is wearing his sport safety sandals
Yeah those latest ones really are great at air circulation.
yea from safety point of view its much better than flip-flops 😁
I feel sorry for the new seal.
Knowing this lot they will construct it from some old leather from a dead rat.
If it leaks, they can just use toilet paper to clean up..
Oh never mind, one hand to wipe the other to eat
New seals and oil come cheaper than a new Rod :)
@@JJ-jv1gu Wrong country and wrong religion...but hey, ignorance is your friend, my friend!
@Tech Overkill the old seal was blown out you can see it in the beginning of the video
One thing never changes in the trades is always the one guy getting it done and 8 others watching, lol!
The use of a straightened rod versus a new one has fiscal considerations.
Physical considerations, I suppose you mean.
Почему я не удивлён от того что у них загнулся шток гидроцилиндра?
Который тон на 100+ расчитан
my dear friend friend...it seems that they don't follow any science or engineering....
Одни специалисты загнули, другие выровняли
They had a sling sitting right there. Tie it to the hydraulic end, then tie that to the frame of the truck, use another sling and tie it to the other end of the hydraulic arm, tie that sling to the working excavator and drag the bucket on the ground to separate the piston from the cylinder. It's pretty simple lol.
I can't believe they were hitting that hardened steel, over and over and again in the same spot.
Necessity is the mother of invention...let's face it parts are probably non existent or prohibitively expensive..it's more than likely a dipper arm or bucket arm ram on a machine that's been to the moon and back that's gets bent and straightening it is not the end of the world and gets it back on the road again..not everyone has access to a fully equipped workshop with all the latest gear......I have been in similar situations myself and greatest respect to these guys getting the job done..
Может им кто-то подарит учебник, по сортам и свойствам металлов...

The funny thing is, this is filmed at a cat dealership in America after one year of Joe Biden.

I suspected at the beginning that renewal of the bent ram was very unlikely.
