Особенно мне понравились отверстия под маслосъёмным кольцом😂

Именно. Уже так начали и у нас делать.

Так ты блок не видел штоли как делали под это колено?))) Советую посмотреть, там похлеще технология))

Це завод запчастин ТАТА?

"только не понятно чо он там" главное участие

Я не технарь, но у меня огромные сомнения относительно допусков по размерам и т.п. ну а в целом, все от бедности...

Поршень на дизель, там степень сжатия ого-го. Точность изготовления так себе. Как будут работать такие детали большой вопрос.

Это скорее всего делают на старые двигатели на которые и запчасти ни делают. Как рассказал мне старый шофёр на "захаре" Если в дороге застучал двигатель вместо шатунного вкладыша кусок брючного ремня кожанного ставили и до дома доезжали.

И ни одного одинакового, все уникальны

Poor quality is an understatement, the distance from gudgeon pin to the piston crown wasnt even measured so every piston is going to have a different height which will give different compression ratios in each chamber. Doesnt matter anyway, i doubt they last more than a few hundred kms.

This kind of work takes a long time, right?

If they had what the western have you wouldn't said this s**t

It takes all days, and it's not running true in the lathe, hahaha 😆 🤣 10mm out off centre 😄 😆

Do you make better?

@@bonarasmey5563 камера сгорания выполнена в поршне, что является стандартной конструкцией для грузового дизеля, и она действительно смещена. Так задумано

Да я думаю что лучше едет чем наш АвтоВАЗ😁

😀😅

Son de ése hierroo muy bueno.👌

Это норма.

Поле допуска у них не в микронах, а в гектарах)

Ты сверлильный видел ? Там сверло бьёт плюс минус полметра. Поэтому , их не волнует вообще ничего. Наш русский Иван Барыгин заказал красивых поршней миллион штук , они налили и наточили. Теперь дело за типографией, и варить жаждущим. Была одна чума, Китай, теперь эти на нашем рынке будут.

I actually can distinguish it from the original... This video was actually a good reminder to think and check very carefully before buying any aftermarket parts.

You can put a set of these in any truck you repair and then you will learn to distinguish from original.......

It will fail very quickly, and goes into the metal pot again.

It's a low revving diesel and not an 18krpm race engine. It'll be fine.

@@Henrik.Yngvesson Dunce!

@@Henrik.Yngvesson Clueless.

I see basic metal failings throughout these and similar type videos in that heat treatment is not understood whatsoever. I'm not sure if the workers genuinely don't know or perhaps they do know and as you say the components will soon be back for a rebuild. Perhaps it's done to keep themselves in employment! Decades ago when needing to repair small 2T motorcycle engines we had two options: Genuine parts or cheaper pattern parts. We soon realised the false economy of pattern parts - the metal was of very low quality with dubious alloys used and questionable grain structure showing. Even when meting the aluminium (and other things) down for this video they do not sample for quality before casting. No additives are used for removing gas bubbles from the metal mix either.

@@jackking5567 Silica alloyed aluminium often used for casting is not heat treatable. And it will go through heat cycles in the engine afterwards.

Their skill will be useful during zombie time

I couldn't said it better 👍

Yo construí un Bugatti en mi cochera y utilicé materia prima reciclada,tiene mejor calidad que los de fábrica,no subestimes la vieja escuela .

They are old bed ford engines and been over hauled many times even there crank shafts are made locally old fashioned. And they are good enough to run thousands of kilometers.

they run bruh they drive they trucks 15000 ft in the hamalayas on mud roads constantly dodging huge rocks and mudslides we got our fancy machines cnc and mig and tig and cmm and qc but out overpriced over engineered lemons wont deal with any of the stuff theres do

They are obviously achieving tolerance or they wouldn’t have a business but god know how?

Yes

tiene razón amigo, y el costo debe ser muy elevado, por una pieza que no reune las tolerancias que dá el fabricante.

Around 13:35 I started getting a sinking feeling about this whole endeavor.

You cannot be that ignorant. All pistons and all cylinders have to be perfectly round or they will never work. In fact when any engine wears down the top and bottom of it's crankshaft path over time also renders them useless.

You are ignorant. Having spent 4 years as an apprentice for a company who made diesel engine cylinder components I k ow how pistons are made. They are only truly round when they are hot! This is because the piston is not a uniform shape and it changes with heat expansion. We used a specially adapted lathe to turn the pistons. The company (Wellworthy) was 100% supplier to Cummins and Perkins in the UK when I worked there.

@@about2mount read my reply.

@@simondegrave2620 Ive read it, Kisten ive been a diesel nechanic all my life. I've constantly rebuilt cats, cummins, Detroit's, several volvos, and several Iveco trucks powered by Ford Desiel engines. Of all of those engines all of them are precisely round to perfection. Ive also miked them, I've had to bore cylinders on several mills, and I've turned down allot of pistons on a Mazak computerized Lathe as well. Fir the sakevof saving yourself tell us all what tool botes all cylinders? Its called a fly cutter and its only set to bore oerfectly round holes in all engine blocks and in all diesel sleeves. So your mistaken. But maybe you mean ballancing weights where pistons front and rear have to match both sides in balanced weight. In thst case the large diesel engine pistons have added counterweights cut into them for ballancing. I think that is what you are referring to. However the pistons dianeter and the skeeves dianeters are perfectly round and have a size diffence of .002 to. 004 deoending on desired compression ordered by preferred choice. For either 10.0 to 1 or up to 11.5 to 1 nominally. Which the 11.5 to 1 would be the tightest clearance of .002 thousands of an inch or less..
