There are many such video clips of differential gears being repaired, crankshafts, camshafts, etc, but how come we never see the engine running? How come we don't see what it's like six months from now? I have my doubts and I don't think I'd like to be around when the customer comes back asking for a refund. Alex Ivanov, below, no, it's not cast iron. It's cast steel, look at the swarf while it's being drilled. Cast iron swarf is granular, steel produces spirals. An HT welding rod will do it but then the pinning bolts should also be HT. But they would appear to be mild steel because they're galvanized. HT cap screws or hex sets are black as a rule.
Steel repairs are not supposed to last long but long enough for the other existing cracks to fail first, that is the economic for repair, it is meant to get the last ounce of use out of an otherwise full of cracks part
it is forged. I am a machinist and the crank is probably at least 4140. rod most likely 7018. half the tensile strength of the crank. he didn't v it out, not that it would of help. no penetration and welding alloy steel. zero chance it will work.
that is a cast iron crank that never welds, it will snap again along the welding seam. steel bolts have different thermal expantion and will cause bending forces inside, and which is more the bearing surfaces are riuned, there is no way to polish or ressurect them. the crank is trash. p.s.someone tell them to measure bearings instead of oil seal surface
Hola saludos desde Venezuela.. Que buen trabajo... pero no entiendo porque Reparan algo y al mismo Tienpo tratan de Dañar otro... se Devio Protejer los puños donde van laa conchas de Vancadas y de las Bielas ese Cromo es Muy Delicado.. para próximos trabajo protejalos exitos y muchas Felicidades... Exito Dios Bendiga esas Manos hombre luchadores...
@@v.d.5242 Да думаю не только и ставят такие и двигатели в песке перебирают, я сам в шоке от этих мастеров, так ещё и с нуля колена делают на коленке вот они и ломаются😂
This is fake, that crank would snap straight away as the weld is in the area where the force is high. You can weld on cranks but not on a fracture like that. These guys are just doing this for a video the crank will never be used.
ЛАДНО ЕЩЁ ПОРШНИ ГОРЕЛЫЕ С КОНСКОЙ ВЫРАБОТКОЙ В ОВАЛЬНЫЕ ЛЫСЫЕ ГИЛЬЗЫ ЗАСОВЫВАЮТ И СОБИРАЮТ ! НО КОЛЕН. ВАЛ ЛОПНУТЫЙ ВАРИТЬ И СЫРЫМИ БОЛТАМИ СТЯГИВАТЬ ЭТО КОНЕЧНО ТАЛАНТ !
C'mon. Don't be a hater. That was a legit repair. I've done that a bunch of times. Everything from big diesels to nascar engines. They all hold up perfectly. The only thing I would have done differently is use softer bolts. Those ones looked too hard. 😂😂😂😂
Anything can be "fixed"....but l guarantee that this crankshaft won't hold up once installed... l know how they abuse and overload their equipment in those countries.
@@user-sx3kn9iz5j ну да. Расскажи как и чего ты добился? Наверное, все нищие мечтают недоедать? Пацану из бедной семьи из умирающей деревни где нибудь в тайге, конечно, только захотеть и стоит, чтобы "всего добиться"
Hello ATO. That all looks like a carpenter fixing a table leg. Dowel pegs and all. This must be one of those scrap bin jobs where busted parts are “fixed” for the video. Sure hope Utube pays them well. On the other hand, that’s probably a crankshaft for a top fuel dragster. Maybe John Force Racing gets their cranks from ATO. Always wondered what those fender stickers stood for. Now we know.
Nothing amazing about it. This crankshaft is out of round, out of balance & the structural integrity has been compromised. Klinger.....you screwed the pooch on this one...GUARANTEED comeback!!
That should last maybe a day or two. Operators in that part of the world routinely overload or otherwise operate their machinery well past reasonable parameters. Always.
Nossa, esses caras são doidos. Da o maior trabalho tirar o motor, desmontar,retificar, montar de novo e colocar no lugar pra fazer uma gambiarra dessas, eu aposto que não dura nada. Eu achava que o Brasil era precário...
I would never put that crankshaft in a mobile application, subject to starts, stops, sudden loads. Maybe continuous duty in a water pump or generator etc. And even then...light loads.
Ничего удивительного не увидел , у нас в России до сих пор так делают многие. Камазисты и не такое могут делать. У нас это считается, низкокласифицированный и дешёвый ремонт . Это и правда не надолго . Единственный плюс, что человек не без дела сидит.
I suspect these guys have done this before.....ok would not happen in the west....but sometime we have to do what we have to do with what we have to hand. Yes I would like to see how it stand up in action....but at least they try.....maybe some are ok for a while and they are happy with that. If the could go to the dealership and get one off the shelf Im sure they would.
I appreciate what your saying, but at the end of the day there somethings that just cannot be repaired to a level required by the forces that are going to be applied. It's a matter of physics not economics.
I am proud of this man and hard work he puts in. But I won’t drive that car. The first downshift the load on flywheel will take the wheel true the car like saw blade . No way Wielding the cast crank on room temperature with stick rod damn
Most of the trucks over there running under those patents. Trucks are very old and there is no parts, this engine probably is of road engine for the fields or generator.
