Caterpillar original Diesel Common Rail Fuel Injector C-9 Engine 172-5780 217-2570 Cross Reference 235-9649 Replacement for OEM 10R-7224 for Excavator Loader E330C 330C 330C L original new injector

Precision-engineered as an original Caterpillar component for C9 and C9 ACERT diesel engine platforms, the 172-5780 high-pressure common rail fuel injector delivers accurately metered fuel to combustion chambers under extreme operating pressures. As a core electronically controlled fuel system part, it syncs with the engine control module to adjust fuel delivery timing and volume based on real-time parameters including engine speed, load, intake conditions, and coolant and fuel temperature, ensuring consistent, regulated fuel supply for reliable engine performance.

Each injector is built with heat-treated alloy steel and micron-level precision-machined parts, including hardened control valves and precision-ground nozzles optimized for uniform fuel atomization. Every unit completes factory bench testing and calibration to meet or exceed OEM specifications, supporting efficient combustion, optimized power output, reduced fuel consumption, and lower exhaust emissions. Its corrosion-resistant construction and thermal stability enable thousands of operating hours of service under continuous heavy-load conditions with proper maintenance.

The 172-5780 is interchangeable with multiple cross-reference and remanufactured part numbers to simplify global spare parts procurement for B2B buyers. It is compatible with all listed C9 engine variants and suitable for a wide range of industrial applications spanning construction, mining, marine propulsion, power generation, oil and gas, agriculture, material handling, and heavy-duty transportation, making it a versatile replacement component for heavy equipment fleets and maintenance providers.
