Personally as a engine builder I could point out a million things that drive me crazy watching these videos !! But I’m so impressed with the work these guys do with the very limited resources!!! Very entertaining to watch
You know, as a gearhead I doubted the engine would even run until the end, but I think they did a decent job. I wouldn't count on the durability of that block anymore though. They'll have to do that more and more often with each cycle
I work in a official caterpillar dealer, we rebuild engines with all technology and tools to make an perfect service. It's so perfect that caterpillar gives another serial number to the machine as an brand new engine. I'm impressed what these folks can do with so improvised and simple things. It's satisfying to see the pre heat process.
Retired machinist here. For years i had people tell me you cant reliably weld a casting....only braze. then you watch guys who dont listen, filling holes and welding cracks in a lasting way. the preheating and low oxygen - carbon charcoal environment seem like a GREAT idea. 8:32 This guy knows what works and what doesn't. He'd make $$$ bank fixing old tractors in the American midwest!
Brazing is a good reliable and repeatable repair for cast iron. You being a retired machinist, would you risk a customer's engine block or piece of machinery on a repair like this, that has a 30% failure rate or with brazing that has a1% failure rate? Keep in mind you have to warranty your work. ☆Disclaimer☆ I don't know the exact % of failure, just a educated guess for my question.
There are no legitimate welding shops that would even bother doing a repair including brazing on stuff like this. Most welders can’t gas weld cast iron anyway.
@@Happy357mag brazing in this situation wouldn’t make sense. Brazing has its place, but this ain’t it. If this repair could have been done with brazing, don’t you think these guys would be brazing it???? Think about it..
@@yamahajapan5351 Not true, heavy equipment shops do cast repair all the time, its just done as spray weld. this hand filling is just neat though, in a BBQ! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zgv9gAXssgM.html
All i can see is skilled crafts men working with what they have. At first i was doupting how much this is in spec but with the use of inserts and piston cover as template in improvised free hand machining was incredible to watch come together.
"Are you sure you got the block completely cleaned out?" - "Sure, I brushed the mud off it with a handful of straw, then squirted some random oil on it from a Mountain Dew bottle, and the wiped it a few times with a dirty rag." - "Perfect."
Just shows you how picky modern engines are. Old fords could run forever on oil changes where the new oil is the dirty oil from a tractor's oil change. And old chevy engines could go 50 miles with no oil, then run with no problems after oil get put in.
When I saw the hand grinding of the cylinders and head I was worried but once you actually sleeved it and decked the head properly I changed my mind. Amazing work and just goes to show how so many things can be repaired that in most places are just replaced.
everything can be fixed and repaired the problem is, is it worth it. for some brands parts alone will be well over the cost of just buying a brand new item. That's the problem.
@@monstereng43 Yes, everything is fixable. The problem is that here in the United States labor is NOT cheap. For someone to do this kind of work they would charge soo much money that you could pretty much pay dealer price for the part you need at that point. Everything here is crazy expensive. Can't even have your entire car reupholstered without paying an arm and a leg. A quality paintjob that will last starts off at 4-5k, basically more than some of this older cars that need a paintjob are actually worth. Additionally that 4-5k you sink into the car is not even an investment at all. Just because its flawlessly painted people are not going to pay you the price of the vehicle plus what you paid to paint it... Not long ago I bought a 99 mitsubishi eclipse GSX with plans to restore, needed interior/exterior work and engine work but I can handle engine work on my own, also had a bit of rust. When I started adding all the numbers It was actually smarter to just buy a mint one from bring a trailer, literally paid a fraction and now I have something that is actually worth something, all mint flagless original paint, no rust, low miles. This was before covid when all these older iconic cars skyrocketed in price so it was actually a solid investment on my end...
Это не экономия друг. Вся эта работа займет больше половины цены этого блока, они ремонтируют их из-за того что нет производства или доставки в их регион.
@@HAMMER13 экономия была бы, если он любой другой ДВС быстро закинул в свой трак и поехал зарабатывать деньги, а тут неделю из хлама делают новый хлам, которы скорее всего день поработает и умрёт опять...и опять простой,опять безполезный ремонт и так по замкнутому кругу...Эти люди просто не знают, что лучше один раз потерять, и потом много получить, будут терять и терять пытаясь из говна и палок что-то слепить... Да и опытный разумный человек просто увидев такой ремонт хоть раз сразу поймёт, что хорошо эти ребята не сделают, а сделают тяп-ляп лишь бы крутилось, и так сойдёт!)
I love these videos. Look at all the old master craftsmen passing down their skills to these young men and boys. This is precisely what the U.S. industrial workshops looked like until we regulated ourselves into obscurity. Mark my words, they will become titans in industry the way the U.S. used to be. They have the old machinery, the know how, and the regulation free labor that breeds competitive incentive. We were the captains of industry, and now it’s these folks. Congratulations, you’re well on your way to the top. We’re dumb enough to think we can just buy and sell success. Not so.
Я так понял что оказывается для ремонта блока необходимы: дрова, мангал, болгарка, дрель, баклашка с водой и длинная палка для переноски, а и молоток...))))
Ещё нужно: Расписная тарантайка для перемещения, дед-колдун с шайтан-паяльником, дядя с сигаретой для расколупалки, молодой расколупальщик с большим вращающимся булыжником, и три раза огромный фрезер
95% of success on this type of work is down to heat. Preheating, and more importantly, proper post repair heat control is the key. Mad skills considering the primitive conditions
Welcome to Cuba, where there's never been anything new since the 50s because nobody wants to economically support the communist regime. Or many other places like it, where there's very few if any new things imported or made domestically through economic sanctions or abject poverty. So they have to make do, and you'll see people doing valve seats and crankshafts by hand and reconditioning old burned up engine blocks like this.
I weld on cast iron every now and then, it's very important to get the cast iron hot and keep it from cooling too quickly after welding. I usually have a metal bucket of sand and a fire blanket to prevent the part from cooling too quickly and cracking. I understand what they are doing here but I seriously doubt that it would be very strong. I guess if all you want is to buy a little more time on an engine past borrowed time, this is one way to do it.
ofc because you dont have enough experience in casting metal because when you melt the iron very important to get melted iron not very fast cooling because it will make the end product crack now you understand why they use carcoal?
i really like the fact that people in the streets are doing diy high tech, and saving tons of money. here in europe, if you have to fix an engine would cost as much as the brand new car.
where's the high-tech? I didn't see any... Anyway, the reason it costs so much to fix stuff here in EU is the price of labor. There are companies in EU that remanufacture expensive car parts like engines, gearboxes, starters, alternators or AC compressors, but they do it at volume in a specialized factory, where they can afford the investment in actual high-tech and the skilled workers *and* produce remanufactured parts that meet OEM spec.
They do it the expensive way actually, that's why they are poor but have a lot of work to do. Harvesting California almonds with a machine takes one man and the machine only, the guy all day long doesn't leave his machine seat once. The cost per one almond harvested are close to nothing, but just two get employed - the man on the harvester and the computersystem in the bank taking care of the incoming constant stream of revenue. All others go trailerpark. (And with hardcore capitalism most of the time the bank is in charge, not the self-governing of the people.) (Some of the people no longer employed here may join the army (instead of heading trailerpark) to make shure that the number of Almond farms grow as far as our influence reaches. And there are other jobs, but few.)
Там на второй минуте работник очки защитные одел!!!! Что за беспредел устроили! Дайте людям спокойно работать без ваших техник безопасности и не стой перед ведром с расплавленным алюминием!!! ("сарказм") А не все нормально, на третьей там уже другой в отверстие дунул через трубочку) Они по уровню блок в землю закапали - я валяюсь... Дед с горелкой топ конечно, не первый раз его вижу
Ну русские конечно всех обосрали, они же всё лучше умеют, научились у других...а хотя о чем это я, мы же ничего не умеем, копируем у немцов, японцев, американцев
this was just fucking incredible. Taking a sledgehammer to those cylinder sleeves while his assistant held the plate & had his fingers inches away from being completely destroyed was the chef's kiss...
as an Aerospace engineer, I watch this and at first I wasted to laugh, then I thought about it a little bit more. The skillz needed to do this project with the tools that they had access to was incredible. Just the part where they pre heated the block to be able to weld it. That's hard to do with the proper tools.
I'm an Aerospace Machinist and Programmer. I understand they're doing what they need to do to survive, and this is really their only option, but we also both know that this is basically not something that's going to last 100k miles, it's survival mode. That said yeah, most people on Earth couldn't even do it with the proper tools.
Aerospace engineer?? Impressed?? You got no clue what’s really going on here and how pointless and crappy the results are. If you are who you say you are and impressed with this quality of work- our space program is doomed
In a throw away world i wonder if anything gets chucked out, the cost difference in getting it done here and getting it done at a dealership must be an eye opener , these guys are so skilled
if you found out what these guys get paid you would cry... the good thing about a society in which nothing gets wasted is the fact that nothing gets wasted... the bad thing is someone has to do this for next to nothing to make it worthwhile... its like paying $200 to get a toaster which would cost $50 to replace fixed... its sad..if nothing else these guys get my utmost respect
Saw a similar video where they hand casted cylinder liners too. It all looks very primitive but the first version of any machine in the Industrial Revolution was probably made in a similar way.
Cnc machinist here. I make pneumatic post pounders. That engine will last 20 miles tops before that patch job they did fails. Also when you rebuild an engine the smallest chip or debris can really screw you over. That's why on some engine machine shops they really stress clean everything. I am willing to bet money that an oil passage is clogged with dirt on this engine. I don't see it lasting 17 miles before blowing up. Plus that finish bore on the liner they installed needs to be a 32 micron or better(stupidly smooth) or else it will eat those piston rings till there's nothing left.(I also went to school to be a diesel mechanic) also judging by the water passages in that heavily warped block I am gonna say that block is gonna go into a dumpster. There is a rule you never do big welds on the block because EVERYTHING moves. Small touch up welds are fine but when you heat up the block you warp it. Then the crank bearings, the cam bearings(if it's ran in the block, think v8 engines for example) are no longer in line meaning the holes are not straight. In conclusion i can keep listing more and more issues but that block is a boat anchor because they don't know what they were doing.
Its actually the right way to weld cast iron. U gotta keep it hot while u r welding. He didnt just get old doin nothing. Thats called experience. Hes fully confident abt wat he did m these things do work man. We as modern men we dont knw shit, we depend on machines but no experience of aur own.
perfect service congratulations... I really admire this work here where I live there are no more mechanics just change the parts....you are true and unique.....
the reason for replacing parts instead of repairing them is not experience, but economics. Those who work with their hands know this problem, because it often happens that it is cheaper for the customer to give a new part than to repair the part. It often happens in practice that a customer comes with a stupid question: why does it cost so much money? I won't pay that much for it...
Looking at the conditions they work in this is perfect job. They did everything right with what they have. The negative comments left out from people that do not know to even take it a part. Also, this is worth doing because of the extremly cheep laber. If somthing like this going to be done in USA it would cost like a new car because it is way too expencive to pay the people with knowledge to do it.
Ну почему же? Есть ролики и из США с восстановлением блока цилиндров. Только оборудование выше классом и соответственно трудозатраты меньше. Хотя согласен - детали от распространенных двигателей никто бы не стал восстанавливать.
Судя по комментарию вы тоже слабо представляете процесс капиталки мотора, который и делают, потому что нет средств на новый мотор, ни говоря о машине. А вообще в вашей стране проще купить машину поновее, ибо у вас б/у стоит копейки, причем такое б/у которое у нас считается чуть чуть подержанным.
@@andrei_shut потому что бюджет этого ремонта банка пива и два бутерброда без мяса. А купить рабочий двигатель, даже контрактный, для них это работать всем населением улицы месяц. Они не от хорошей жизни всей этой хуйней занимаются.
@@user-bd2ow5dh5l возможно ты прав. Знать бы их цены на токарные, фрезерные и сварочные работы, тогда б понятно было. Но возможно это восстановление ради видоса было. По типу, когда филипки мопеды сжигают и оставляют на улице, а потом видос о восстановлении делают
It doesn't matter, they replaced the old material with new material.. they have to open the hole out enough to get a propper weld in there without porosity or cold lap
Definitely looks like a Perkins block 100%, I would tend to think its a AD 3-152 block from a very late 135 or an early 240 because it has four studs to hold the lift pump on, 35's and early 135's had two bolt hole lift pumps. Also far as I can remember a 35 engine has 15 head studs where the 135 has 18 head studs, this repaired block has 18.
Да у меня вообще вопрос: сколько они наварили к плоскости, и сколько потом сняли? Как они ловили размеры? Смотрится, будто наварили где-то сантиметр, а потом сняли столько, сколько Будда на душу положил
Я ничерта не понимаю в ремонте но тоже подумал, на тему, допусков/точности и тп. Что наверное таким способом можно ремонтировать какой нить трактор времен Черепанова, но ремонт технологичного современного двигателя, с гарантией работы, вряд ли.
The process is amazing to watch but I can't help but wonder how many workplace accident these guys have. I don't know how many blocks these guys make a day and how much they earn but given the right conditions and tools, their level of output would be amazing.
