Perkins original Perkins Fuel Injector Nozzle 1OR-7231 Common Rail Injector 10R-7231 for C15 C18 Excavator new injector original new injector

The Perkins C18 fuel injector 1OR-7231 is a precision-engineered common rail diesel injector designed as a direct OE replacement for Perkins C18 series engines. Built to OEM specification with hardened internal components, high-strength alloy steel construction, and a low leakage design, this injector assembly delivers consistent fuel atomization, high pressure capability, and electronic fuel injection performance for demanding industrial environments. It cross-references directly with authorized OE numbers 10R-7224, 10R-7222, 387-9433, and 328-2576, providing a reliable equivalent solution for global aftermarket and OEM service channels serving the Perkins C18 engine platform.

This injector fits the Perkins C18 inline 6-cylinder diesel engine with 18.1-liter displacement, including the C18 ACERT, C18 Marine Engine, C18 Generator Engine, and C18 Industrial Engine variants. It is engineered for application in Perkins 374D, 385C, and 390D excavators, 992K and 994F wheel loaders, 777F, 773F, and 775F mining trucks, C18 generator sets, marine propulsion engines, oilfield equipment, and crushing equipment. The component undergoes rigorous multi-stage testing and OEM bench calibration to ensure proper spray pattern, injection pressure, and engine compatibility across mining, construction, marine, oil & gas, power generation, quarry, agricultural, and industrial manufacturing operations.

Routine maintenance supports long service life, including fuel filter replacement every 250-500 hours, fuel system inspection every 500 hours, fuel pressure check every 1000 hours, injector testing every 2000 hours, and complete injector inspection every 4000-6000 hours. Operators should use clean diesel fuel, replace damaged fuel lines, follow Perkins service manual procedures, use calibrated torque tools, and perform injector coding when required. The injector addresses common fault symptoms such as hard starting, black smoke, white smoke, power loss, rough idle, high fuel consumption, misfire, and excessive emissions, and is backed by a 12-month warranty with industrial export packaging.
