The KOMATSU S6D140E-5 crankshaft (Part No. 6261-31-1200) is a high-performance replacement part specifically designed for heavy-duty engine repairs. This forged steel crankshaft is made from 40Cr alloy steel and offers 27.9% higher tensile strength compared to traditional cast iron crankshafts, ensuring exceptional durability under high-load conditions. A precision induction hardening process creates a 3–5 mm hardened layer with a surface hardness of HRC 52–58, enhancing wear resistance by 15% over nitrided cast iron alternatives. It is an ideal choice for maintaining engine performance and reliability in demanding work environments.

(2)Medium Frequency Quenching (Heat Treatment)
KOMATSU S6D140E-5 crankshaft is treated with medium-frequency quenching and tempering, leaving quenching marks on the surface.The quenching layer depth is 3–5 mm, with a hardness of HRC52–58.
(3)Advanced equipment
The crankshaft is precisely machined using CNC equipment to ensure that dimensional tolerances strictly meet the technical standards of the engine. The main journals and connecting rod journals undergo multiple stages of fine machining and surface hardening treatments, which not only improve surface finish and balance but also significantly enhance wear resistance and extend service life.
