original 10R-7230 Diesel Engine Fuel Injector for C15 C18 Engine Excavator 988K 990K 390F L 395 Fuel Injectors Pump 291-5911 253-0616 Replacement for OEM original new injector

Engineered for demanding heavy-duty diesel operations, the 10R7230 HEUI fuel injector delivers precision fuel atomization and reliable injection performance for C15, C15 ACERT, C15 SDP, C16, and 3406E engine platforms. This OEM-equivalent replacement is directly interchangeable with cross references 10R-7230, 2360962, 236-0962, 3282574, 328-2574, 20R8064, 20R-8064, 3879433, and 2490713, providing global fleet operators, aftermarket distributors, and OEM service centers with a dependable sourcing solution for high-volume replacement programs.

Manufactured with precision-machined nozzle technology and high-strength alloy steel construction, the injector features wear-resistant internal components, corrosion-resistant surface treatment, and OEM-calibrated fuel flow rates. Its high-pressure injection capability ensures stable operation under severe duty cycles, delivering precise fuel metering, improved combustion efficiency, reduced fuel consumption, lower emissions, enhanced horsepower, and faster throttle response. Typical applications include Peterbilt, Kenworth, and Freightliner highway trucks, mining trucks, drilling machinery, commercial marine vessels, diesel generator sets, and industrial pumping units used in oil and gas field operations.

For optimal service life, use ultra-clean diesel fuel, replace fuel filters regularly, and perform periodic injector balance testing. During installation, clean the injector bore, inspect the seat, replace O-rings and seals, lubricate before fitting, apply OEM torque specifications, prime the fuel system, and complete ECM calibration if required. Symptoms such as hard starting, black or white exhaust smoke, power loss, rough idle, or engine knock often indicate injector wear requiring immediate replacement.
