🔹Product Overview

Crankshaft Part No.3918986 is the core rotating component for 6CT and ISC8.3 diesel engines, widely used for excavators, heavy‑duty trucks and engineering machinery equipment. It converts the reciprocating movement of pistons into rotational power output, and bears complex alternating impact loads during long‑time engine operation. This replacement crankshaft solves serious engine failures such as abnormal knocking, violent vibration, metal clattering, journal wear and shaft bending deformation caused by damaged original crankshaft. Each crankshaft has passed strict dynamic balance testing, hardness inspection and dimensional tolerance detection before being packed in wooden cases for delivery.
