original 328-2577 3879438 10R476 Diesel Fuel Injector Common Rail for C9 C7 330D 336D Excavator Spare Parts new injector original new injector

The 328-2577 diesel fuel injector is engineered specifically for the C9 engine, delivering precise fuel metering and fine atomization to support efficient combustion in heavy-duty excavator applications. As a direct replacement injector GP, it is built to match the original equipment specification for C9 series engines used in 330D, 336D, E330D, E336D and E340D excavator models, ensuring reliable fitment and stable performance under demanding operating conditions.

This injector assembly supports engine power recovery and helps maintain fuel economy while contributing to controlled exhaust emissions. Its durable internal structure is designed to handle sustained high-pressure injection cycles typical of construction machinery service. Workshop installation is straightforward, and the standardized part numbering simplifies inventory management for distributors and maintenance teams.

For optimal service life, use clean diesel fuel, replace the fuel filter on schedule, and drain the water separator regularly. During diagnostics for hard starting, rough idle, black smoke, white smoke, engine knock, power loss, misfire or excessive smoke, inspect injector performance and conduct return flow testing if leakage is suspected. Always keep the fuel tank clean, store injectors in sealed packaging, and maintain strict cleanliness during installation to prevent contamination-related failures.
