original 267-9722 Common Rail Diesel Fuel Injector 2934071 293-4071 for C7 C9 Engine 330D 336D Excavator Fuel Injector Nozzle Assembly original new injector

Engineered for demanding industrial applications, the . C9 HEUI Fuel Injector 267-9722 is a precision-built diesel injection component designed to deliver stable fuel atomization and reliable performance across heavy-duty engine platforms. This injector assembly serves as a direct replacement for OE number 267-9722 and is fully cross-referenced with alternative numbers 267-9710, 267-9717, 293-4074, 328-2580, and 387-9431, as well as remanufactured references 10R-7223 and 10R-9003, providing versatile sourcing options for global maintenance operations.

Built to OEM specifications, the 267-9722 injector integrates seamlessly with the C9, C9 ACERT, C9 Industrial, C9 Generator, and C9 Marine engine platforms. Common equipment applications include the 330D and 336D excavators, 950H, 966H, and 972H wheel loaders, 140M and 160M motor graders, 725 and 730 articulated trucks, alongside C9 generator sets and industrial power units. Key performance benefits include precise fuel metering, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and enhanced engine power output backed by a 12-month warranty.

Correct installation is critical: clean the injector bore, replace O-rings and sealing washers, follow torque specifications, and perform injector coding or calibration where required. Recommended service practices include using OEM-grade fuel filters, regular water separator draining, clean fuel supply maintenance, periodic fuel pressure inspection, and injector balance testing to ensure long-term operational reliability across construction, mining, marine, and power generation sectors.
