Caterpillar original Caterpillar C7 C9 Engine Fuel Injector 267-9717 for Excavator, 236-0962, Replacement for OEM 328-2576, 235-5261, suitable for 330D 336D E330D E345 D325 original new injector

The Caterpillar 267-9717 fuel injector assembly is a brand-new, OEM-standard diesel injection component purpose-built for the full range of Caterpillar C9 engine variants, including C9 ACERT, industrial, marine, generator, and power unit iterations. Manufactured to strict Caterpillar engineering requirements, this electronic unit injector is validated for C9 engine platforms operating in high-demand industrial environments, and is shipped in industrial export packaging with warranty coverage available for bulk and individual commercial orders.

Operating within a high-pressure electronically controlled fuel injection system, the injector responds to ECM signals to activate its solenoid and precision needle valve, atomizing pressurized fuel to enable controlled, efficient in-cylinder combustion. Its precision-machined nozzle, wear-resistant internal parts, and corrosion-resistant housing deliver accurate fuel delivery, extended service life, and harsh-environment reliability. OEM-standard calibration supports plug-and-play fitment, while optimized atomization boosts combustion efficiency, raises power output, reduces fuel use and emissions, stabilizes idling, and improves cold-start performance.

The 267-9717 injector fits a broad portfolio of C9-powered Caterpillar equipment, including hydraulic excavators, wheel loaders, motor graders, articulated trucks, generator sets, marine engines, and mining and industrial machinery, serving global construction, mining, marine, and power generation sectors. Routine maintenance per Caterpillar specifications, including regular fuel filter replacement and scheduled injector inspections, maximizes service life, making it a reliable replacement solution for equipment fleet operators, maintenance providers, and industrial parts distributors.
