original 10R-9787 Diesel Engine Fuel Injector for C18 C11 C10 3406E 3456 Construction Machinery Replacement OEM 211-3026 2113026 10R-0724 10R9787 original new injector

Engineered as a direct-fit replacement for OE 10R-9787, this C18 diesel fuel injector delivers reliable high-pressure fuel atomization for demanding industrial engine applications. Cross-referenced with part numbers 326-4708 and 3264708, the injector is fully compatible with C18 Series, C18 ACERT, Industrial C18, Marine C18, and Generator C18 platforms powered by the 18.1 Liter inline 6-cylinder turbocharged diesel powerplant.

Built with high-precision manufacturing processes, the injector features superior atomization performance for cleaner combustion and optimized fuel economy. Wear-resistant materials and integrated corrosion protection ensure high-pressure resistance and stable long-term performance under continuous heavy-duty operation. This component is widely deployed across the Construction, Mining, Marine, Power Generation, Oil and Gas, Quarry, Transportation, and Agricultural industries, supporting excavators, loaders, generators, marine propulsion units, and other mission-critical equipment.

Common diagnostic indicators requiring injector service include hard starting due to nozzle blockage or internal wear, excessive black smoke from poor atomization or leakage, white smoke from incomplete combustion or timing issues, high fuel consumption from worn nozzles, and engine power loss from restricted flow or contamination. To maximize service life, operators should use high-quality diesel fuel, replace fuel filters regularly, drain water separators frequently, avoid contaminated fuel, and conduct routine engine diagnostics. Bulk B2B procurement and fleet-scale supply are available for industrial buyers.
