Crankshaft with gear for Komatsu GD511A

The crankshaft 6207-31-1100 functions as the primary rotating component within the internal combustion engine. It converts the linear reciprocating motion of the pistons into rotational motion, which is then transferred to the drivetrain to power the machinery. This specific unit includes an integrated gear, which ensures precise synchronization with other engine systems, such as the timing assembly and oil pump, to maintain coordinated operation.

This component is engineered for the Komatsu 6D95 engine, which is utilized in the Komatsu GD511A motor grader. The crankshaft design incorporates counterweights to balance inertial forces from the pistons and connecting rods, helping to manage internal engine loads. The main and rod journals are precision-machined to interface with the engine bearings.

In any internal combustion engine, the crankshaft acts as the backbone of the power delivery system. By rotating within the engine block, it provides the necessary torque to drive the machine's transmission and hydraulic systems. Proper alignment and balance are necessary for the crankshaft to function correctly within the engine block, ensuring that power is delivered smoothly throughout the operating range of the machine.
