Bien hecho Su servidor en estos casos de deformación Rectifico de 0.002" a 0.003" y se verifica la medida con los cojinetes intalados y sobre de esa medida se rectifica el cigüeñal con la medida que muestra esl micrómetro Para dejar la tolerancia que me especifica el fabricante En ocaciones tengo que dejar el diametro más grande.

Yes sir, thank you

[@KenFullman]

Was this perhaps caused by overheating?

[@CCAssurich]

Yes sir, a lot of factors to consider and overheating is one of those. When the engine overheated the temperature goes up and when the engine is very very hot can cause a lot of internal parts clearances changes and the engine oil also becomes very thin and if the oil is very thin the oil pressure drops. If the oil pressure drops can cause insufficient oil supply to the bearings.🙏🙏
