My time machine only lets me travel 13 days into the future. I can say, without a doubt, that the part was in excellent working condition when I observed it.
Respect the fact that these people can do more with nothing than you can with everything. Critique all you want if you're in "developed" world but having individuals like this, at the ready, to make repairs is astounding.
Welding on a cast steel part, then grinding down the outer diameter will change the tooth engagement, grinding off more tooth material will just cause more slop unless it’s shimmed correctly. It will get it out of town or to someplace with a replacement part. But it’s not a long term fix
Bro, they barely have tools, let alone _"tolerances"_ ... As long as it works, it'll be fine. I'm astonished that he even managed to recover that piece's original form... Most western technicians in the same conditions, would have deemed the task as _"impossible"_ ... Give that man a bit of credit...
That’s some beautiful handiwork, the temper is what I’m worried about. That thing is going to shatter/bend with a load that the previous harnesses would’ve handled. Still tho, hell of a way to get it back on the road. Hell of a job.
Yes very true...they lost me when they started grinding all the other teeth - although it looks great, it now will no longer interact with its companion gear as it should, the tolerances or gear lash will be immense. I speak as a qualified, practicing engineer with 15 years experience. Hats off for ingenuity though, necessity is the mother of invention👏👏👏
@@Bugsy0333 master is a stretch. They’re just guys working to feed their families. Give me two weeks with you and I’ll have you doing this job just as good as they did.
Сыромятнический наварил, эвольвенту зуба на глаз вывел. Если эту деталь потом в сервант на полочку поставить для красоты, то работа проделана не зря)))
They are just eyeballing the dimensions so while it may look good, it’s probably 10 to 30 thousandths off in places, and that's a fatal amount of error. Not sure why they applied bluing to the crevices, that's the only place that does not need it, and we didn't see them test-fitting the gears and following the blueing indications. And it’s not surface-hardened. So it’s going to run very rough and not for long.
I agree with everything you said. But For them to be able to do this. Especially eyeballing means they’ve done this before. I’m gonna have to lean towards this is going to be good.
Exactly this type of repair might get it by but it's deffinantly not gunna last like the original gear. Also gear teeth are usually only case hardened the new tooth is much more brittle not to mention the tolerances being eyballed and they took the grinding wheel to all the teeth. Looks Shiney and pretty to the average person but at the end of the day this thing is just a pretty paperweight and a bandaid fix. I understand they gotta do what they gotta do in 3rd world areas where parts may not be available
I was going to ask….. and again I’m not a mechanic…. Don’t you have to have really tight tolerances in this kinda stuff, all that material he took off would cause it to leak, wobble, hammer, shift, loose compression right?
I mean maybe if he tig welded tool grade filler rods on? Than maybe? I’d feel like it would hold up a while but idk I appreciate the craft and what they have to do with the means they have but that thing gon break
And I thought he was just going to disassemble and reassemble with a nee part not that he's actually going to fab up the broken piece literally incredible
Hmm what about the tolerances ... A mm off and wouldn't it fail to work in whatever engine / drive train it came from ... Work looks beaut , but like , would it still work ?
concidering on how overloaded they run the trucks. hand cutting the teeth pitch is only creating an issue on its own..but they can rebuild the crownwheel to match.
Very crude way of repairing a gear pinion gear rather. As some one said in Pakistan tolerance is not a problem it seems. 🤭 however good you are the product should serve its purpose not only in terms of working but in terms of perfection and durability. Today you repair it and tomorrow you find the main driver or something else is broken what is the use. Super glue technology.
Карл,это очень бедная страна как ты видишь..но даже в таких условиях они стараются и делают казалось бы невозможное!и обрати внимание сколько там эти промежуточных валов, видимо есть спрос на их работу..это конечно не на долго,но какое-то время точно прослужит...а у нас бы просто выкинули
Some machinist can work to +-.005 with just their eyes on scribed lines. Some heat treated rears last over 400 thousand miles, I bet this will last longer than the people and the truck as long as they don't beat it and keep oil on it.
In my opinion which no one cares for or asked out the tool gave out already just get a new one because you don’t know when it’s going to give out again
beautiful work but probably useless... there is no way to guarantee the necessary precision in manual work, in addition to the lack of hardening of the pinion
He over built the material so he could grind it down ... he has the other teeth as references come on guys you can see he's been doing this for a while now
Мля, у нас на МАЗ- е на рембазе точно также делают, хотя нет, у нас хуже делают. И даже если делают из заготовки, шестерни для станков, то максимум на зубонарезном фрезой, без шлифовки. Типа притянутся, ну и стучат с самого начала. Вы что разве не знаете девиз рембаз?!?! "И так сойдёт". Так что они ещё пиздец как ахуенно сделали.
Yea I'm a tool and die maker and fairly new gear mechanic and this is all bs. That's a polished turd. If you're impressed you obviously don't know, so do yourself a service and look what just a regular straight involute gear tooth looks like. Then a beveled gear, and then a helical beveled gear. There was no measuring even done. So shiney doesn't equal good not to mention the metallurgical issues with how they did it. Respect the hustle but not the product.
Hello my fellow citizens. I’m a time traveler from the year 2025. And I have came back to this video to say that is repair only lasted two weeks.
My time machine only lets me travel 13 days into the future. I can say, without a doubt, that the part was in excellent working condition when I observed it.

I’m convinced they just “fixed” it for TH-cam views and then it gets tossed in the scrap pile

@@Steevo69 yeah, I know…
Holding the pinion in that rag while polishing it scares the shit out of me.
Engines in Pakistan must have very loose tolerances.

They get them from a to b and that's all you need
This is for a differential , not an engine.
I am curious how long it will last
Tolerance are very necessary but it's a local work shop you know what I mean local
They are assets of our country don't blame them..
My Safety manager would be so sick to see this😂😂
I thought the 10 year old was gonna be the expert machinest

This guy is a master i bet you this part will last longer then a new one which is what would have been done here in the USA.

it wont last :(

This is why they don’t need mass production of the same model every year
Thats amazing you guys are working in pyjamas
All these comments about whether it's going to last.... Ffs. If it gets some out of a jam, what are you worried about?
Главное в шестерне не модуль зуба а блеск!
in this gear, the correct shape is not important - the main thing is beauty and brilliance
concidering on how overloaded they run the trucks. hand cutting the teeth pitch is only creating an issue on its own..but they can rebuild the crownwheel to match.
Nice sculpture.

You you "fixed" a hardened steel gear with mild steel and polished it? Hope it's going in a Prius.
Ни фига...шевронную передачу на глаз...😁, а термообработка, им главное, чтобы блестела...😂

Dude they barely have tools
This is not a fix. This is a money-making enterprise.
Great shop
Помню, что на практической механике, учили проводить хим и термо обработку шестерени. Видимо, в процессе на данном видео - это лишнее.

А цементация? Горсть песка в редуктор и все притрется.
Guy had a whole lathe. Wouldn't exactly call that minimum.
Duralast “ quality right there!
I want to say they should of heated the thing up before welding it

When you buy valucraft remanufactured at autozone instead of new
High quality facility there I don't see that lasting too long 🤣
its nice work but it will be back in no time because it is going to fall apart. You can rebuild a gear using a stick weld lmao
agreed its not accurate anymore
Hi good job
This dude out here stick welding pinions...in the dirt.

Шестерни полировать нельзя, только шлифовать, а то масло не будет создавать масляную подушку.

Вопрос? Сколько проходит?
The moment i saw they are wearing longsleeve while doing lathe.. im convinced the repair will not last long 😅

Great job but that thing gonna break in 1 week 😂
What can make the break on a pinion? This thing should be unbreakable
Complete gear metrology gone.

This repairing is temporary type .
I can hear the hmmmm from here
Cute peperweight.
Omg. I cringed so hard when he was polishing on that lathe with a long sleeve. Accident waiting to happen. Smh
What in the fuck is he soldering with Lmaoo
Will last about as long as, oh yeah it won't... Same effect as trying to "repair" a bearing...
I surely hope whoever driving the thing that uses that pinion would survive...
This the type of machining you would get from Ohio AINTNOWAY what the HELLLLLLLLLLLLLL
That'll be 2 rupees 🤣
It won't last long😂
آپ آپ کے چینل کی کیٹیگری کونسی ہیں آٹو موٹر
It will never be as strong as it was....only shape is the same....nothing else. And those tolerances....
Recalento soldando y luego no hizo un tratamiento termico para unificar durezas... Después devastó todos los dientes.... una locura
And then it broke the next day
Those are not even real beads, his welding is terrible.
Yah and then they sell the pinions to autozone hahaha
Useless repair. Now tolerance and gear meshes is way off.
Mucho brillo y el tratamiento térmico donde está? Esto es "pan para hoy y hambre para mañana". 🧰
завтра он вернётся по гарантии и будет снова хлеб
Dales creditos por lo menos estan mas industrializados que muchos paises de latinoamerica

Looks good but thats a BIG weak spot though.🤦
