В процессе изготовления ни разу не использовались измерительные инструменты. Только верный глаз и твердая рука.
Я даже не знаю, что прекраснее литье или токарка :) С другой стороны если сразу пускать опять в переплавку у них же, то и норм.

За всë видео ни разу не применяли измерительные инструменты. Вот что значит мастерство!
пхахахахаахах))))
Примерно таким образом и в ссср для себя делали. Батя рассказывал что такие поршня «росли» и приклинивали в цилиндрах. Их вынимали протачивали и так несколько раз. Это все было от незнания того что алюминий калится, старится и естественно при литьё из металлолома нужно добавлять лигатуру.
Когда я по заказу изготавливал поршень на какую-то импортную косилку то и элипс точил и конус и под палец за одну установку растачивал.
Лигатуру честно не применял негде было взять. Термичку естественно тоже исполнял. И все работало!
Картингистов тоже выручал но тут все сложнее. Режимы эксплуатации очень жесткие. Иногда поршня рассыпались на кусочки и ресурс был в общем низкий.
Применяя знания и умения можно и гараже делать вещи. Но в этом видео конечно показано полнейшее непонимание многих нюансов.
я думал, что из люминия без литья под давлением нормальных по эксплуатационным качествам детали никак не сделать.

@@fonar-pro вы правильно говорите. Но с применением газоотводящих присадок специальной лигатуры и опыта даже в гаражных условиях получается достойно.

Соосность отверстий под палец, сделанных за два прохода, будет просто шикарной! Сам палец надо забивать кувалдой и прихватывать потом аргоновой сваркой, так как канавки под стопорное кольцо - нет.

@@bykvskijjevgenijj да возможно что там под плавающий палец поршня но эти товарищи не пользуются какими нибудь маломальскими измерительными инструментоми и делают все на глаз, соответственно будет ли нужный натяг при запрессовки пальца или он нарежет при первом запуске двигателя борозду на цилиндре это только бог знает.

Back in 1980s UK we would sometimes buy piston kits for out 2T motorcycles. Most kits were forged billet but every now and then we'd be sold cast kits. The quality difference was very noticeable and if you had a cast kit you knew you were on limited time as they always failed quickly.
The pistons here have questionable metallurgy never mind machining tolerances.
their 2022 is our 1980...
Must be pistons for Indian or Chinese motorcycles.
@@overdrivelzma.9219 No with that offset chamber in the middle they are most likely for a direct injection Diesel engine. It would be very interesting to compare the weighs of 30 or so. And what is the Silicon content. How much pi

@@overdrivelzma.9219 Did you see the size ? that would be an enormous motorcycle...
@thecouchtripper Lower rpm, but higher pressures. If the cheap cast pistons he describes failed in two-stroke motorbike engines, there's a good chance cast pistons of unknown metallurgy and approximate machining are not going to have a long life in a truck diesel.
Made using the finest CNC*

Could be suitable for a low rpm steam engine or a water pump or something (this is possible as they have all kinds of weird irrigation pumps over there), but I don't believe I'd use it for much more than that.

I love how the fresh castings are thrown on the ground on top of each other. Nothing like adding pre-wear to the piston skirts. Dust and dirt is good for lapping in the rings.
Too poor to have any table or storage boxes
@@juhajuntunen7866guaranteed they're not so poor they can't prevent tossing them around on the ground. A dog could learn to set them down easy.
they get machined afterwards. So there is no pre-wear on the skirts whatsoever. The dust can be easily cleaned before being put on the machine
@@dieselgeezer18 They throw the freshly “machined” parts on the floor and in a big stack. All the washing in the world won’t help that.
@@rxpsycho7326 you said in your top comment that the pistons were dropped right after they were casted, not machined
OMG! wth? are you kidding me? I'm retired from Wiseco piston in Mentor . Our pistons were forged from 4032 and 2618 alloys, we had rigid heat treat procedures and tempering formulas. Also proper fixtures and job specific tooling, what most people dont understand is the piston skirt is turned oval (out of round)for a reason! The head and ring groove area is solid and expands evenly as the engine warms up and spreads the pin boss apart there by distorting piston skirt making it rattle (piston slap) oval turning prevents that in the first few moments of engine start up as piston skirt is perfectly round now.
This is a rip-off, OEM, pirates or would you say, it's a local spare part being sold with no brand, it's cheap, so cheap than brand new og certified spare parts, where I come from and other develop country used this kind of technique
Hey, used many a Weisco piston in HP Stock Car and Road Race engines, but I don't think you will find too many in the HINO trucks they use over there.
I have no idea how they get away with it but from the looks of the castings they have laying around apparently they do it every day. (BTW, I live in Mentor)
@Ligia Gom HA HA HA HA.....
THIS IS PURE COMEDY...!!!!
@Ligia Gom yeah surprised if they last more than a couple of hundred RPM on tick over.
Hey! You are supposed to say what they do is amazing because they live in the stone age and can spin and cut some metal.
The recess in the piston top indicates it is for a diesel engine. So does the full skirt, up to a point. Modern design pistons are not round. The piston is slightly elliptical so that when the engine reaches design operating temperature, the expansion of the aluminum piston makes it become round. They left flashing in a number of areas such as the skirt bottom and the wrist pin bore. These pistons have to be for a low load, low rpm engine such as the single cylinder engines that they use on water pumps, etc. Even at a maximum speed of 1800 rpm, these pistons would probably wear rather rapidly and develop piston slap in whatever engine the pistons were in. And as others have mentioned, the questionable carbon intruded alloy could be brittle.
Maybe these are roughed out blanks that go on to final machining in an actual machining operation? I can't believe that is a usable piece as is. Still the casting is a joke.
Who governs the quality of aluminum or steel?
In a one cilinder it wil last not verry long. If it's a 4 cilinder or more, all the pistons have to weight the same. Otherweise the engine wil shake itself to pieces by unbalance. 1 gram differance is a killer olredy.
Can anyone tell whether zinc aluminum alloy is good for making pistons of bitzer semi hermetic??
Indeed. Pistons are not round, the are oval, if new. Careful selected metallurgical composition and heat treatment made them last a while in older cars. Modern pistons are forged.

It is good to remember where we all come from and how things started long time ago.
Pistons and housing castings are made of different alloys. Housing alloy is typically A-380 with 3% zinc, .10% magnesium maximum and 1% iron content. Pistons are made of SAE 332 alloy with .80%iron max, 1% zinc max and about 1% magnesium. They are making these pistons out if a bastard alloy. There is a reason for the element content of different alloys. I wouldn’t want to be the one carrying the warranty.
They look like pistons for an old DI engine. Originally I think they would be manufactured from a cast Iron.
What damn warranty?
Sweet a dipship than can use google and copy and paste and thinks he looks smart.
You said it precisely.
I kind of knew that one can't make Coke cans into durable pistons, but I did not have the figures like you, hence I didn't open my gob earlier. But...
I'm getting a distinct feeling that 'those countries', to generalise, don't care much about quality, safety, innovation, environmental targets, workers' life.
Anything is possible, and they make clones very close-looking to the original, but the repair might be short-lived. Skilled people slightly off track.
But, hey, they do theirs we do ours. I hope they don't export to western discounters.
But one thing pisses me off big-time.... The western nations are leaning out the window right now to halt the effects of their environmental mistakes, but 'those' countries don't seem to have a bar of it. Don't follow, don't know or don't care. They happily pollute on like the West did since the industrial revolution until now more or less. Unfortunately the planet is shared and it don't care where the CO2 (and other stuff) comes from. I wonder if 'these' places have active Governments joining in....?
Is this "Brass- Balls Nagel"? Erik Nagel from Opie and Anthony? JK bro, you are so right about a "bastard alloy", they can't expect quality when the alloys being melted are unknown and mixed with oil and dirt and all other forms of carbon and contaminants. These pistons may be used in a under 5000 RPM diesel generator, but anything else risks catastrophic failure at high RPM, which would turn the engine and its components into shrapnel and twisted metal. A dangerous form of manufacturing. All the best Nagel.
Start-to-finish… this is exactly how *not* to make a quality piston.
Mixed alloys, water dunk, dropped on the floor, triple chucked on three different surfaces, wrist-pin holes machined separately (and not reamed?), sloppy oil holes, burs galore. Was it annealed?
Then there’s the basics.. ambient material temp expansion corrections? Micrometer zeroed for non-standard temp?
I dont expect full tilt cnc over there, but we’ve been doing better than this since the 1930’s.
But how many have you made exactly?
This guy knows what he’s talking about is true how the hell this people expect that piston to work properly when no measurement at all was taking not one but you know I guess quantity is always better than quality who cares I’m not surprised if this pistons make it to the market like this why we getting shit parts lately even when you buy brand name parts
@@outkast187 but but but.. I see you’re one of those guys. 🙄
I’ve made much more complicated and precise items than pistons, they’re relatively straightforward. Pistons have a simple job; dont crack, dont melt, dont gall and dont slap.. the hard part is done by the rings. The problem with this piston is its used in a diesel with twice the compression of a gasoline engine, the metallurgy is critical and so is a perfectly square and aligned wrist pin. As shown in this video, its junk from birth.
I never made a piston in my life. But when he machined the wrist pin hole, my first thought was, how does he know the other hole will line up?
@@XD-te6vj They line up perfectly......or they will do when the wrist pin has been installed with a sledge hammer.
Imagine trying to get 6 identical pistons!! As a machinist I’m horrified!
Even a hobby level machinist would be horrified. Watching him reef down the hard jaw chuck with a cheater bar direct onto the already machined ring land area had me cringing.
And yet, this was how stuff were made 50 years ago...
@@mitsos306ify No, fifty years ago in Western countries and Japan etc the quality control was orders of magnitude better
@Ligia Gom Obviously he is.
I feel sorry for whoever buys it!!!
Интересно посмотреть на это поршень через час работы на моторе.
Если добавить в масло верблюжьего помета, притрется, обтешется и будет работать. 😂
Что с ним будет на моторе, в моторе работать будет не долго.
Pistons are designed with a taper, the tapered shape compensates for thermal expansion and thermal growth. The piston crown gets a lot hotter, therefore the top of the piston expands more than at the base of the piston. I’m fairly sure the pistons seen manufactured in the video were being machined parallel.
"parallel"
Also modern pistons aren't round, they're elliptical, not to mention these are made with completely unknown metallurgy. I'm like 90% sure this whole operation is just done for CZcams views (2.2million!). Can you imagine hand-sawing the "sprues" off every single one with a hacksaw like they did? Insanely inefficient.
@@truthsmiles no you are wrong this is not for YT they really do like that and are pretty good, of course not automated, pretty dependent on manual work quality but they have great success according to what technology they use. Metallurgy is ok, the similar is done in most of car production factories, melting old engines and making new from that...
So you measured the tolerance with your eyes?
The geometry of the piston is broken, usually the bottom of its piston (skirt) is wider than its top. Such a taper of a few hundredths of a millimeter is difficult to mass-produce on a universal lathe.
As an engineer at Rolls Royce we would go to the scrap yard and take the old pistons and make them into ashtrays
Only sad thing was I never made one for myself
наверно это наше будущее ))

Using only (cleaned) pistons as stock rather than filthy, oily mystery metal parts would be a good first step.

Even pistons are made from a range of alloys that would not be compatible. I have seen ingots of raw material, made to a grade for die casting wheels

Ручная работа! Кастом!
Your supposed to grind a slight ovality on the piston so there is room for the metal to expand across the wrist pin where there is more mass of material. How you can maintain accuracy by keep taking the tool bit out of the toolpost or tilting the toolpost around is beyond me.
Come on brother this are ancient tools made by Khufu 😝
You should not expect any quality product out of this kind of sweatshop with the kind of material and tools. Everything is junk.
I suspect that these are sent to another company to be properly finished. As shown, I think that these would not do the job in a real engine.
@@jeffreyfwagner oh but they’ll try.. seems they have way too many people needing something to do, so their economy is built on “good enough for now, we’ll fix it again next week”. Thus, 10 guys make another piston after 5 guys pull it from the engine, again. Repeat.

To all the negatives comments out there, I 100% agree with you but look at these guys manufacturing at a different angle. It's obvious that they do serve a community and have been doing it for awhile. So for what ever purpose these pistons are made for, they got to be working otherwise this manufacturing facility would not exist today as they would not have repeat customers hence no sales. but obviously not the case here. Let's wish them well and good job based on the community that they are serving.
The negative comments are coming from people that have been living in a bubble of privilege. They haven't seen what most of the world looks like still. These folks in the video are at least being productive and not starving and waiting for handouts. Their engineering, machines and systems are primitive by comparison to first world, but they're filling a niche and putting food on the table. If they had our luxuries, they too would have clean shops, latest tools and equipment and methods. But hey, they'll get there soon hopefully.

It's sounds very crazy to me but also fascinating as with little equipment they can make some kind of pistons.
Now go look at a video of a Marle piston factory and see how many dudes are wandering around the CNC production facility in dirty holed-up T-shirts. This is all those guys know, it keeps them and their families in food and sandals and probably the single-cylinder air-cooled water pumps going for agriculture. Also look at a town called Dar el salam (I think that's right) on the production of all types of firearms Colt 1911s, Glocks, AKs, whatever you want sir, with guys using their feet as vices, hand files, and hacksaws, these are determined people, I can not dislike them.

Amazing how they repurpose the old and create new - very impressive 👍 lots of negative comments without knowing where these pistons are being used, I doubt they are going into a Ferrari race car. Maybe a pump for water or some other light duty use.
Did you even read the title? It’s fairly clear what the piston is intended for ( it’s truck )🤨
that aint no water pump piston , are you blind ??
Everything in an engine has to be very precise… i feel those pistons would seize up in the bore or damage the sleeves
Good engineering skills here. These pistons are good quality diesel truck pistons. This particular company has been in business for decades and supplies pistons to Hino, mitsubishi, Toyota , Mercedes & Deutz.

So this is how Royal Enfield pistons are so cheap on ebay 😂😂
Watching them work barefoot or in sandals working around metal like that just makes you shake your head. Drop something on their toes would be bad. Haha
а им по хую ...👍🐒
I think you new here🤭
Always wondered where the diesel knock came from, and now I know.
It comes from India
Pakistan ... not India
These are Pakistan. A semi isolated country. India can make decent quality parts,, I suspect all western designed and tooled. But made in India. Reputedly the Royal Enfields while a lot dated are still relible bikes.
Super precision!
Молодцы!!!
What alloy are you using?
Yes
the buyer might care.
20% Coke, 20% Fanta and 60% Lemoade can.
Those chuck jaws were being used outside their safe limit. Far too much sticking out, bet it was only holding on 2 teeth. Highly dangerous. I have always thought that pistons were machined on a special machine as they are were not truly round. Regards from Australia.
Ok forte abraço
Nobody cares where you are from! Regards from your mother's bedroom.
Eso sí es calidad de trabajo 👏👏👏👍
Great job everyone. Somewhere there a machine that will be vital to a community for fresh drinking water and these pistons will make a pump work for years, or some type of farm equipment that will speed up the process of an old tired farmer.
Thank you Sir !
Most of the commenters do not seem to understand that.
These are the ones using astronomically expensive vehicles for recreation.
If there was not a market out there for these pistons, there would not have been a video for them to shred !
Not too many Indian, Pakistani or African farmers can purchase a John Deere or Cat !!!
Trinidad & Tobago.
West Indies.
somewhere there will be a machine vital for it's community for fresh drinking water and it will be destroyed if someone installs this piece of crap into it. poor community.
Homemade pistons 🤣😂😂😂 it's working in engine? 😂😂😂🤣🤣🤣
I wish that .... but what is the reason of laughing?? They did a good job
@@ahmedmohammud5293 using CNC machines 🤣🤣🍌
I really want to hear the massive knock when someone is crazy enough to fit one of those pistons in an actual engine, and the diesel spray from the nozzle hits that raw ass combustion chamber. I start to shudder even thinking about that. I am kind of sure that said engine will blow apart instantly if it comes under load. Creepy sh*t.
I’d like to see the “truck” driving with those!
it's amazing work and nice skill in India. i like your video. it's good creative.
I have never seen a worse drilling job
You aint been around. YOu should see some of the Ironworkers I have had work for me. Some of them could screw up a crow bar.
The accuracy of the machining is unmatched by any cnc machine in the world !
Well, unless they made it... 😂
На глаз без замеров, без весов?👍
