original 20R-0056 Common Rail Fuel Injector Assembly for C12 C15 C18 3512 3516 Engineering Machinery Parts new injector original new injector

The C12 fuel injector with OE number 20R-0056 is specifically engineered to match the combustion requirements of C10 and C12 diesel platforms, including the C12 ATAAC, C12 Marine, and C12 Generator configurations. This unit injector integrates directly with the engine's high-pressure fuel system, delivering metered diesel charges into each combustion cycle under precisely controlled timing. The component cross-references 350-7555, 170-5252, 203-7685, and 10R-1268, giving fleet operators a consolidated solution for replacing original equipment in 345B, 345B II, 365B, 365B II, and W345B II excavators, as well as wheel loaders, articulated trucks, and other mining and agricultural machinery powered by the C10 and C12 series.

Manufactured according to strict dimensional tolerances, this 20R-0056 injector features hardened internal components, wear-resistant nozzle assemblies, and corrosion-protected external surfaces to endure the harsh operating conditions typical of construction sites, mining operations, and marine installations. The optimized nozzle geometry promotes superior fuel atomization, supporting cleaner combustion and more stable idle quality across varying engine loads and ambient temperatures. Its compatibility with the 3176 and 3196 engine families further extends service coverage for legacy and current equipment lines used in industrial power generation.

Routine daily inspection should include checks for external fuel leaks, abnormal exhaust smoke, irregular idle behavior, and unexpected power reduction. Scheduled replacement according to manufacturer service intervals helps maintain consistent injection pressure, protects the cylinder head and pistons from contamination, and preserves the long-term reliability expected from a genuine C12 fuel injection component in heavy-duty commercial and off-road applications.
