Original 20R-8068 557-7637 10R-7221 20R-8968 236-0957 10R-9002 Diesel Engine Fuel Injector For Excavator C9 original new injector

Engineered as a direct fit replacement for the C9 diesel platform, the 20R-8068 common rail fuel injector delivers OEM-grade fuel metering performance for heavy-duty industrial, construction, marine, and power generation applications. Cross-referenced with 328-2574 and 10R-7225, this injector integrates seamlessly with high-pressure fuel systems used across the C9, C9 ACERT, C9 Industrial, C9 Marine, C9 Generator Set, and C9 Power Module engine families.

Built with precision nozzle technology and corrosion-resistant materials, the 20R-8068 injector ensures consistent fuel atomization, enhanced combustion efficiency, and stable engine performance under demanding duty cycles. Heavy-duty construction supports long service life, while calibrated spray patterns provide precise fuel metering that improves fuel economy, reduces black smoke, and lowers exhaust emissions. Typical equipment coverage includes the 330D and 336D excavators, 966H and 972H wheel loaders, 140M motor grader, CS563E compactor, C9 generator sets, marine auxiliary units, and industrial pump and compressor drives.

Installation follows standard OEM procedures: relieve fuel pressure, remove the injector cover, extract the old unit, inspect the bore, renew seals and washers, torque to specification, and verify for leaks. Recommended diagnostics include resistance checks, fuel pressure verification, spray pattern inspection, return flow measurement, and ECM fault code scanning to ensure optimal system reliability.
