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?

Realy good like old german Manufakturing style

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...

To me it looks like the material is too soft for a crankshaft. Forged steel would do better.

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

A cast steel for a crankshaft??????????????Amazing butchery!!!!!

i, too, enjoy polishing my crank

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?

Taki wał i technologia to może być dla śilników 2 tlokowych czy max 3 tłokowych. Zasada jest jedna jeśli ktoś kupi taki wał to w naszym kraju musi iść ponownie na osiowanie, wywarzanie i szlif !!! Obowiązkowo !!!. I z nominału robi się już 1 szlif przy wale nowym jeszcze nie zamontowanym. A i tak bałbym się zkładać bo to jest plastelina. Jak by spadł z małej wysokośći to by odkształcił by się. Ciekawe jakie różnice są na wysokośći korbowodów, i chyba nie mówimy o x,00 a raczej x,0 . Bo tutaj jak w chinach byle się kręciło. A wał jak pochodzi 2 lata to max. Czy mi się tylko zdawało ale tam chyba ani razu nie użyto mikrometra !!!. Te wały są do śilników gdzie są starej daty. Bardzo mało koni ,nie wysilone lub i pracujące jednostajnie na wysokich obrotach. Bo do ciągnika strach to założyć. Jak Czop główny tylko środkowy jest sprawdzany.

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

the most hilarious part is the balancing of the crankshaft . all tolerances are in 2 fingers spec.

It is a very clean well organised shop with purpose made equipment in good condition - far better than what we normally see.
