Caterpillar original 265-8106 Diesel Fuel Injector for Cat C7 C9 Engine Assembly Components Replacement for OEM original new injector

The Caterpillar CAT C9 Fuel Injector 265-8106 is a high-pressure electronic fuel injector engineered for CAT C9, C9 ACERT, and C9.3 diesel engines used in demanding industrial environments. Designed to meet original Caterpillar fuel delivery specifications, this injector delivers OEM equivalent performance for construction, mining, marine, oil and gas, and power generation applications. It is compatible with excavators such as CAT 324D, 325D, 329D, 330D, and 336D, as well as generator sets, mining machines, and industrial power units equipped with C9 power systems.

Featuring a multi-hole precision atomization nozzle and hardened internal components, the 265-8106 fuel injector provides accurate fuel metering and superior combustion efficiency under all load conditions. The corrosion-resistant surface treatment protects internal parts from sulfur contamination and moisture exposure, while the robust design ensures reliable operation at pressures up to 1800 bar. This makes the injector suitable for continuous heavy-duty use where consistent fuel delivery and engine responsiveness are critical.

Routine maintenance is straightforward with recommended service intervals every 250, 500, 1000, and 2000 hours, including fuel quality checks, filter inspections, injector balance testing, fuel pressure verification, nozzle spray pattern testing, and complete fuel system evaluation. The 265-8106 is cross-referenced with multiple part numbers including 235-5261, 238-8092, 242-0857, 254-4330, 254-4339, 254-4340, 266-4446, 267-3360, 267-3361, 267-9710, 267-9717, 267-9722, 293-4073, 10R-2828, 10R-7222, and 10R-4764, ensuring broad compatibility for replacement and remanufactured service needs.
