Можно выколоть глаза,особенно понравилась запрессовка и "плоскошлифовальный" человек
I sometimes think we "over engineer" things, we used to make parts for engines, angles to 15 minutes of a degree, spent a lot of time checking keeping everything on spec, they sent an engineer to Japan he toured the factory, the Standards Room was not temp controlled, instead of using a sine bar and checking angles the just used a DTI indicator and a couple of marks to show limits. These guys might look like they are building well outside anything the west would do, but they get things done quick and it works, it looks rough and ready, but it works, they have my respect for working in less than ideal conditions but still getting it done.
As is said.... "sh*t will run"
The timing of when the west went to stricter standards coincides with the power and reliability increasing. They get it done sure but it won't last as long before the next rebuild and the a/f mix will be farther on the rich side to compensate for the larger variances.

It's disturbing seeing all those parts laying on the dirt, but then again, maybe it's clean dirt.
Its clean, pure and autoclaved dust...lol
They mix it with water and they have brake cleaner
Break in takes 5 minutes with all the abrasive dust. Of course it doesn't last too long. Repeat Customer!

I'm always amazed by some of the tools that you have. The boring machine I have never seen one that small. Normally you have to take the engine to the machine. I love to be able to find one of these that you were using here in the states. I am getting ready to do a Google search and find out if they are still available or can I find one that has been used. As always loved your video all of you are brilliant at what you do I really love watching all of you work together. Your videos are some of my favorite on KZhead. I always make sure to watch them as soon as you put them up. Of course I always make sure to hit the like button and I've been a subscriber since your first video. Looking very forward to seeing your next one.
Hey David. The Boring Machines you see in this video are fairly common in our part of the world. Not as common in use nowadays. But some shops still make a good living using them. There are many different sizes available. Right down to a fairly small size for Lawn Mower Cylinders. But these usual came with a small base to mount the Boring Machine to rather than mount the machine on the small cylinder. I think there are Chinese copies available on ebay if you have a look on there. The company that made them in my country originally was a company called REPCO. They made all sorts of engine reconditioning equipment. IF you want to know more about them i can put you in contact with a guy who sells them here in OZ ?
@@weldmachine A good used boring bar machine of this type to look for here in the states is Van Norman. They made really good machines and apparently they don't wear out. If I had to do a lot of this type of work I'd do like I saw another guy on YT do and mount one to a Bridgeport mill on the other end of the ram from the regular mill head. it gives you both the travel and height you need, and the knee is a nice stable planar surface to mount the block to. I'm getting ready to do my Kubota engine with a regular boring head and I need to feed the knee to get enough travel. I also had to make a mandrel extension for the boring head to plunge deep enough into the bore. It's so tight with the block on there that I have about a quarter inch of clearance. If the deck was any taller I couldn't do it on that machine. I did a practice run on the old sleeve and it worked really well, although it was very tedious to set up.
Another brand is Kwick Way. I think the Chinese copies are of that design.
@@randr10 You can definitely do the job well enough on a Mill. As you mentioned a little bit of time to set up. But like most things it's easier when you do it the second time. 👍
David Frank, it’s a copy of a Kwik Way manual boring bar. They are for sale all the time on eBay.
Felicitaciones a todos los que allí trabajan..me gusta mirar estos videos..bendiciones para uds..
Many of our garage workshops in the western parts of the world looked Similar to this in the 1920-1930s but still did good work. Often with only a dirt floor, and not always with electricity either.

That’s not dirt in your engine sir that’s breaking grit. No charge for that !

Nice technique
Niiice! Simple, cheap, quick ) And it works then.
Question is how long...

Remarkable! But please understand that I will be taking by engine rebuilds elsewhere.
@@bigboreracing356 I do, when getting engines rebuilt. You won't be getting my business either. 👍
@@bigboreracing356 Well you care enough to reply - twice.👍
Very nice ji
Good job.
Well where is accuracy?? All dirt around can cause millimeter errors in accuracy which means huge disturbance in performance..
do not worry about little ones, thanks to that they always have work ..
It will cause nothing in fact these engines are capable of picking 5times or load than for what they were made
Couldn't be much worse than what they produce at the Harley Davidson factory.

Nice job
Cool 👍👍👍👍
good job brothers
How can they avoid getting dirt in the sleeves when they work in dirt - I’m amazed at the quality off work in such difficult conditions 👍
They Definitely do a great job especially for they have to work with. Where as guys in our part of the world, spend hundreds of thousands dollars buying top end equipment to do the same job.
This only happed in Pakistan
There forsure is dirt in there...I doubt this rebuild will last more than a few thousand miles.

Hmm...no dial bore gauge to confirm cylinder size, sandpaper instead of stones(roughing and finishing), no plateau brush, no milling the block deck after liner installation. Want a professional guess at the life of this engine after overhaul?
Meets or exceeds OEM specs.
Да... Куда там немцам с японцами с их роботами, станками с ЧПУ, и остальной автоматикой. Завидуйте неандертальцы.
When they reinstall the New cylinder liner to block, why they hit with humer. Actually should be squeeze with thread push or with hydraulic press gently. Now this condition is very dangerous.
Is the same thing , it doesn’t hurt
Dividers to set your bore size, that's a first for me.
Real men do it without a dial indicator bore gauge
как полевой ремонт-оч даже заебись! но если посмотреть с другой стороны-качественного капитального ремонта-то это ЖОПА

I was cringing when he was honing the cylinder with that sandpaper contraption. SMH. After watching alot of these videos I'm surprised there are running vehicles there. This is a horrible engine building environment with everything sitting in the dirt
Its only sand not cement so its cleaned easily
@@informationandnews32 thats if they clean it out all they way. I see soo many cut corners when watching these videos i bet they dont get all the dirt out.
@@bigboreracing356 having a "can do attitude" and building and engine in the dirt are 2 different things. This has nothing to do with having a "can do attitude", im talking about the way they are working on a customers engine. We wouldn't treat a customers engine like that in America. This might be acceptable business practice in your country but not where im from. SMH One more reason im glad to be an American 😁🙏🇺🇸
These lads no what they doing and the customers are very happy with the work as most are farmers, truckers and van drivers who need to be working not parked up. What they don't do is go and stick fingers in other people's countries or the world for that matter and after 20 years blame everyone else for the failure except for themselves, no mate they take responsibility. You keep your" AMERICANISM". did any one ask your opinion I think not.
@@mohammedikram2593 did anyone ask for your opinion here? I think not
I would love to see follow up videos on these rebuilds to see how they're lasting.
Фрезировка высший уровень
Хон супер
In which city?
Oops, missed the eyeballing of the ring end gap to determine final bore size. The machinist's eye is pretty accurate, but not that accurate. 🤣
Nice
Asalamwalekum wohi machine se Haid face karskte na
crazy, but works, they´ve been doing it for decades...
Good work
Back in the day i worked on Volvo truck engines. The cylinder liner height had to be checked when installed and the seat height would be cut then shims installed to get it to the exact height, you’d then put rubber seals on the liner and drop it in with a special grease. Definitely no just hitting them in with a large hammer.
I've rebuilt a few of those engines also. The D12 series engines were actually my favourite to work on. When the cylinder sleeves had the O rings and their special grease, the sleeves themselves were thick and went straight into a water jacket. The O rings were to stop the water leaking out. What they're doing is more common on smaller (Japanese?) engines where the sleeve is just an insert and only as another wear component. The only things I question in this video is the use of oil on the outside of the sleeve and grinding it flush to the block. I vaguely remember using a sealant on the outside to help hold the sleeve in place and stop oil from making its way up in the gap between the sleeve and cylinder bore but it was a long time ago so I could be wrong. I also don't recall ever grinding back the lip of the sleeve. I thought that it's supposed to protrude a bit so that the head would press down on it and clamp it in place.
@@businessbear4076 the liner would sit on a shelf that you'd inspect when the liner was removed. If there was any discolouration or rust it meant the rubber had either let coolant through or exhaust gases and needed shimming. You'd cut the seat down to remove the rust then shim to raise the cylinder up to the correct height using a dti gauge. I was a trained volvo diesel mechanic. No doubt, many would just pull out the liners and just put in new seals.
Grinding a head with hand with grinding stone....hm...wouldn't pay money for this rebuilt.
It’s cleaning, not grinding.
Brother. Pakistani boring ka rezalt acha hy ya china boring machin ka please help
Everyone is constantly hunched over because nothing is on tables. It would be a lot easier on your backs to get stuff off the ground.
Actually it may not. The lower back muscles are constantly stretched so no stiffness.
It’s so they don’t drop stuff on their toes.
Not much different to working as a Concreter. They work in this position everyday all day. Mostly why you don't see to many old Concreters on the job. Just some of the hazards of working in a labour job.
ANYONE SEEN THE NEW PARTS,/??? YER SIR, DE BE ON FLOOR SIRS . WHERE WEDO KEEPS OFTEN ALL OUR REPAIR UNITS, SIR
I always hear the word "use the right tool" for the job. My answer is "what is the right tool when they built pyramid of egypt? Logic: "use the right tool that is available that moment, to make job done.. no reason or excuse the job has not done because if that mindset. Be resourceful and not liabilities.

I just wish my engine had sleeves. Then I could have a new one every few years.
Have it Sleeved!

Este bloco Perkins 4.248 deve ser o de cilindro de 100mm. Daí removeram as camisas na prensa para poder aproveitá-las, futuramente, em um bloco de 101mm. Porque é muita mais rápido utilizar uma faca feita de mola de fusca. This Perkins 4.248 block must be the 100mm cylinder. Then they removed the cylinder-liners in the press to be able to use them, in the future, in a 101mm block. Because it's much faster to use a knife made from a beetle spring.
98,48 mm
@@mevlutgebece2148 na verdade nem um e nem outro. O 4.248 é 101,06mm apenas. O que tem essas dimensões que citei no comentário são os P4000.
Freeze the new jugs if you can. Go in much easier.
Зачем точить новые гильзы?
Pero si tienes la prensa hidráulica úsala 😅😅😅😅😅😅😅😅😅😅
Cheap ways of fixing, but not professional.
It does seem a strange way to work for us in our controlled world. But reality is ? Even engines built in top end shops still have plenty of failures.
k power уже не тот -)
Пакистанский KPOWERtuning )))
The technic they are using for boring it was used in USA in 1920 or 1930.
Many shops still use the same Boring Machines today. Reality is ? There is not that much money to be made in Engine Reconditioning these days. Mostly why the smart shops work to a budget rather than to their egos.
Мы дебилы станки придумываем гильзы в азоте охлаждаем. Тут просто гильзы кувалдой забили плоскость куском кирпича вывели вот и капиталка
Все нормально, и чистота после расточки с помощью переносного станка хорошая. И человек с куском абразивного камня, почему многие смеются? Он не восстанавливает плоскость заново а просто срезает забоины. Только хонингование вызывает вопросы, надо использовать алмазные бруски для глубоких маслоудерживающих царапин на гильзе.
Looks like the secret thread is dirt
why is it boring??🤔🤔
And still got all his toes...

Why they bored again
First bored, then honed.
The second process is honing, this puts an approx. 45 deg. cross hatch pattern in the bore which allows the rings to ride over smoothly whilst retaining oil.
First of all I would have clean the shop and built some racks and tables and get some gloves with shoes. Look at the people hands and feets. You do this every day, so why not working in a propper atmosphere? Dont understand hindu and islamic people, they love to work in poor circumstances
