original 1OR-7231 Common Rail Fuel Injector Nozzle for C15 C18 Diesel Engine Excavator Replacement for OEM 276-8307 10R-7231 High Performance Injector Assembly original new injector

Engineered for demanding heavy-duty operations, the 1OR-7231 Common Rail Diesel Fuel Injector delivers precision fuel atomization and reliable performance for C18 platform engines. This OEM-equivalent injector assembly is designed as a direct replacement for original units, supporting inline 6-cylinder, 18.1-liter diesel engines used across mining, construction, marine, and power generation sectors. It cross-references key part numbers 10R-7224, 10R-7222, 387-9433, and 328-2576, ensuring broad compatibility with C18, C18 ACERT, C18 Marine, C18 Generator, and C18 Industrial engine configurations.

Manufactured with high-strength alloy steel and hardened internal components, this injector features a precision-machined nozzle, high-pressure capability, and OEM calibration for optimal combustion efficiency. Each unit undergoes multi-stage bench testing and rigorous industrial quality control to guarantee low-leakage performance and consistent spray patterns. Typical applications include 374D, 385C, and 390D Excavators, 992K and 994F Wheel Loaders, 777F, 773F, and 775F Mining Trucks, C18 Generator Sets, and marine propulsion units. The injector effectively addresses common fuel system issues such as hard starting, black or white smoke, power loss, rough idle, misfire, high fuel consumption, and excessive emissions.

Recommended service intervals include fuel filter replacement every 250-500 hours, fuel system inspection every 500 hours, fuel pressure checks every 1000 hours, injector testing every 2000 hours, and complete injector inspection every 4000-6000 hours. Backed by a 12-month warranty.
