Perkins original Perkins 1OR-7231 Common Rail Injector 10R-7231 276-8307 for C15 C18 Excavator Diesel Engine new injector original new injector

Engineered specifically for the Perkins C18 engine platform, the 1OR-7231 fuel injector delivers precise atomization and consistent injection pressure across demanding industrial duty cycles. The precision-machined nozzle and hardened internal components maintain calibration stability under continuous high-load operation, while the high-strength alloy steel construction and corrosion-resistant materials extend service life in harsh environments such as mining sites, marine installations, and power generation facilities. Each unit is OEM calibrated and multi-stage tested to ensure it meets original Perkins performance specifications for the 18.1-liter inline six-cylinder configuration.

This injector assembly integrates seamlessly with the electronic common rail fuel system found on Perkins C18 ACERT, marine, generator, and industrial engine variants. It is compatible with equipment including 374D, 385C, and 390D excavators, 992K and 994F wheel loaders, 777F, 773F, and 775F mining trucks, C18 generator sets, and various industrial power units, oilfield equipment, and crushing machinery. The low-leakage design supports stable rail pressure, improved combustion efficiency, and reduced emissions output across all supported application sectors.

Routine maintenance of the fuel injection system is critical to long-term reliability. Operators should replace the fuel filter every 250-500 hours, inspect the fuel system every 500 hours, verify fuel pressure every 1000 hours, and perform injector testing every 2000 hours, with complete injector inspection scheduled between 4000-6000 hours. Always use clean diesel fuel, replace any damaged fuel lines, follow Perkins service manual procedures, utilize calibrated torque tools, and perform injector coding when required. The 1OR-7231 is backed by a 12-month warranty and supplied in industrial export packaging for safe global distribution.
