Caterpillar original Common Rail Injector 1OR-7231 276-8307 10R-7231 for C15 C18 Excavator Diesel Engine Fuel Injector Nozzle Replacement, compatible with multiple engine series original new injector

Engineered as a precision core component of electronic common rail diesel fuel injection systems, the CAT 1OR-7231 fuel injector is purpose-built to match the exact performance requirements of Caterpillar C18 engine platforms. It accurately meters high-pressure fuel and delivers finely atomized spray directly into the combustion chamber, supporting optimal combustion efficiency, stable power and torque output, improved fuel economy, and reduced exhaust emissions for long-cycle demanding operations.

Manufactured in strict compliance with OEM specifications, this injector features a precision-machined nozzle, high-pressure operating tolerance, hardened internal components, corrosion-resistant materials, and a low-leakage structural design. It undergoes multi-stage testing and OEM-standard calibration before delivery to ensure consistent, reliable performance. It is compatible with all C18 variants, including industrial, marine, generator, and ACERT versions, and cross-replaces part numbers 10R-7224, 10R-7222, 387-9433, and 328-2576.

Available in both new and remanufactured options to suit diverse operational and budget requirements, this injector fits a wide range of Caterpillar equipment across mining, construction, marine, oilfield, and power generation sectors. It adapts to excavators, wheel loaders, mining trucks, generator sets, and industrial power units operating in harsh, high-load environments. It comes with 12 months of warranty and industrial export packaging, and supports standardized installation and preventive maintenance protocols to reduce unplanned downtime and extend overall fuel system service life.
