CAT Excavator C27 Engine Crankshaft 219-4453 2194453 Excavator Crankshaft

The 219-4453 (2194453) Crankshaft is a core power transmission component of the Cat C27 series excavator engine. It is made of high-strength alloy structural steel through forging, quenching and tempering, and precision machining, and serves as a key carrier for the engine to convert the reciprocating motion of the piston into rotational power. Strictly developed in accordance with Cat's original design standards, the crankshaft has an overall structure including main journals, connecting rod journals, crank arms, and balance weights. The surfaces of the main journals and connecting rod journals are subjected to nitriding hardening treatment, with a precision reaching the micron level. It is accurately adapted to the cylinder block crankcase of the C27 excavator engine, and works in coordination with components such as the piston connecting rod group and the flywheel. It undertakes the core responsibilities of transmitting combustion explosive force, driving the excavator working device and auxiliary system operation. Widely used in heavy-duty working conditions such as large-scale mines and engineering construction, it provides a solid guarantee for the stable output of the C27 engine.
