original 10R-3264 Fuel Injector Assembly for 3406E C15 C18 Diesel Engine Excavator Truck Replacement for OEM 374-0750 253-0615 20R-1914 Injector Nozzle original new injector

Engineered as a direct replacement injector for C15 and C15 ACERT diesel platforms, the 10R-3264 fuel injector assembly delivers precise high-pressure fuel metering for heavy-duty highway trucks, mining haul equipment, marine propulsion units, and stationary industrial power modules. Cross-referenced with 217-2570 and 328-2574, this unit is manufactured to OEM-level tolerances, ensuring drop-in compatibility, consistent spray patterns, and stable combustion performance across the full engine load range.

Built to withstand the extreme pressures and thermal cycling typical of common rail diesel systems, the 10R-3264 features hardened internal components, precision-machined nozzle geometry, and reinforced sealing surfaces for long service life. It supports enhanced combustion efficiency, reduced fuel consumption, and lower particulate emissions, helping fleet operators, mining contractors, and power generation providers meet performance targets while reducing unplanned downtime. The injector performs reliably under sustained heavy load, harsh dust exposure, and high-vibration conditions common in earthmoving, logistics, and marine service.

To maximize service life, operators should install new seals and O-rings, verify calibration codes where required, use OEM-quality fuel filters, and follow scheduled maintenance procedures including injector balance testing after replacement. This component is a proven solution for resolving hard starting, rough idle, excessive smoke, reduced horsepower, engine knock, and emission compliance issues on C15 series engines used in trucks, generator sets, and industrial power systems.
