Caterpillar original Caterpillar 2OR-8071 fuel injector replacement part for C-A-T engine common rail system new injector original new injector

Engineered as an OEM-grade replacement for the . C7 diesel engine platform, the 2OR-8071 Fuel Injector delivers the precise atomization and stable timing required for demanding heavy-duty operating environments. This HEUI (Hydraulic Electronic Unit Injector) unit is manufactured from hardened alloy steel with CNC machined components and a precision ground needle valve, ensuring OEM specification nozzle geometry and long-term dimensional stability. It cross references to a comprehensive range of authorized OE numbers including 10R-4761, 10R-4762, 10R-4763, 20R-8057, 20R-8058, 20R-8059, 236-0973, 241-3238, 328-2582, and 387-9428.

The injector is fully compatible with . C7, C7 ACERT, C7 Industrial, C7 Marine, and C7 Generator engines used across excavators, wheel loaders, motor graders, mining trucks, drilling equipment, agricultural power units, marine auxiliary systems, and diesel generator sets. Performance benefits include stable injection timing, excellent spray pattern, reduced fuel consumption, lower smoke emissions, and enhanced engine response. Hardened internal components and corrosion resistant materials support heavy duty industrial service life under extreme load conditions, backed by a 12-month warranty.

For optimal performance, always replace sealing washers, inspect the injector bore, verify fuel rail cleanliness, and follow OEM torque specifications during installation. Use ultra low sulfur diesel and replace fuel filters regularly to prevent common failure symptoms such as white or black smoke, excessive fuel consumption, hard starting, engine vibration, and reduced power output.
