Crankshaft for Komatsu

The crankshaft 6162331201 functions as the primary rotating member within the internal combustion engine of Komatsu heavy machinery. It connects to the piston connecting rods and rotates within the engine block via the main bearings, effectively transforming the reciprocating linear motion of the pistons into the rotational torque required to drive the transmission system. This component features integrated counterweights to manage inertial forces during engine operation.

This part is compatible with various Komatsu diesel engine configurations. It is manufactured to precise specifications to ensure proper alignment and fitment within the engine assembly. The crankshaft is a core component of the engine's rotating assembly, and its structural integrity is necessary for the conversion of combustion energy into mechanical work. It must maintain exact clearances with the main bearings and connecting rod journals to ensure proper lubrication and smooth rotation under load.
