I think that this factory is where Ford get their crankshafts for the 7.3 Godzilla gas engine. They are blowing up left and right at around 40 thousand miles. Lol.
Amazing work on primitive Victorian era lathes and machinery. These are talented machinists and mechanics but I'm sure there is a lot of room for improvement to bring it up to par with the rest of the world.

Well, there are cast cranks used still today, but they are Nodular iron (Sg) precision machined and induction heat treated to harden the bearing surfaces, but these are never used in diesel engines, only petrol engines.
Hi Vitor. Are you saying that these crankshafts come out of iron casting mold, but are not reheated and cooled rapidly which would harden them? How do you know these crankshafts are not reheated and cooled quickly? Do they look a certain way and you can tell from their appearance?
@@duckbizniz663 Hardening and forging are different things. Hardening only effects the surface of the part while forging effects the whole grain structure of the part significantly increasing its strength. I can tell it was casted by the surface roughness/pitting and the parting lines 1:06.
@@danielsch8434 There is NO industrial diesel engines manufactured that have cast iron crankshaft, hardened or not. You will automotive petrol engines with nodular iron crankshafts, some are surfaced hardened, i.e. induction hardened at the journal. Good quality diesel engine crankshafts are nitride hardened. So, can you name any industrial diesel engines that have cast iron non hardened crankshafts? I know of medium speed diesel engine that do not have hardened crankshafts, but they are of an excellent quality forged alloy steel.
4 jaw chuck and he never zero'ed out a single surface. Just adjusted it with a hammer and away he goes. I wouldn't ever pay money for one of those cranks, even if I was only going to use it as a boat anchor.
This is the reality of the process for finishing a rough forged crankshaft these days. There was a time when General Motors offered an unfinished crankshaft and a machinist would spend up to 2 days getting the counter weights and journals cut concentric to one another. At some point in this video they will actually put the piece on a crankshaft grinding lathe to finish it to original specifications
This guy is talented ! I love the way he eyeballs the crank into around .030" then uses a stick indicator to get even closer. All brazed tools and a perfect chip mean the best that 'OL machine can make! I'd love to see what he could do with my old XLO454.
I have seen some crankshaft manufacturing for 6-cylinder 3.5 liter engines. The crankshafts made here a much larger, for trucks not passenger vehicles. BMW crankshaft manufacturing seem to be more automated and there seems to be more quality control which are also automated. So where would this production method fall under in terms of durability and precision of specifications. Crankshaft has to work within an engine with other parts. So would this manual production be more accurate or less accurate?
Đấy là đối với bạn còn đối với công nghệ thì các kĩ sư, thậm trí cả chuyên gia người ta đã tính toán và sản xuất chúng ra ko phải là để mình phải bổ sung đâu bạn
They way they lifted that crankshaft, a kid and an old man, tells me how light weight that is, they have no clue on metallurgy, so much labour but not meant to last.
@24:30, look out the window. How can these people live like this. Such filth and garbage EVERYWHERE! On the ground, on their cloths, on their tools, on the parts. I can only imagine the smell!
@Will he heck as like Ductile cast iron is a very commonly used material for crankshafts, not just in India, everywhere. Most OEM crankshafts in general purpose engines are ductile cast iron with cast steel and forged steels being used only for higher performance engines.
Could only survive in low shock applications like generators or automatic gearboxes with torque converters. Nowhere near a clutch. And surface hardening of random cast iron like this is a no-no...
Long sleeves and loose clothing: check No hearing protection: check No eye protection: check Only thing missing is children and a people wearing sandals
Considering the equipment and time given to them the 4 people on the lathes and the old fella doing the balancing did pretty well. Ive yet to see a torque wrench or new oil used on an engine rebuild in Pakistan, they just use smaller or bigger people to tighten bolts down to spec lol It's probably the same people that make the bearings so its all good lol
I mean don't get me wrong I am in no way criticizing the workmanship of these men I've watched many videos and you guys do some amazing things with very little
This might be how they make crankshafts in third world countries. That's a manual lathe. That's not mass production, that's cave man tech at it's finest. GM Ford and Chrysler do things a lot more modern
I wouldn't expect the engines to last long. As a machinist I'm impressed how hard these men work, but they act like they have a gun to their heads. The crankshaft will suffer from this high pressure to make it fast. What some watching might not understand is that the guy was doing a straightening operation AFTER the precision grinding. The roughing operations on the lathes were warping the shafts, pretty badly, so the straightening op with the hydraulic press should be done prior to grinding also. I have to wonder under these working conditions, how many disabled, unemployable men are walking the streets.
Why no revolving tailstock centre! I know it costs money,....but that is just stupid to not have! Wear on fixed centre, plus chatter finishes, oh well, whatever! Cheers

the main journal is always in perfect straight alignment😊
Yes, surprised that it already needed straightening! Relieving built in casting stress.

It gives me goosebumps when I see people working with metal without protection, no self-preservation instinct. 😁

To me it looks like the material is too soft for a crankshaft. Forged steel would do better.
Cast iron is fine for general purpose crankshafts
