Caterpillar original Caterpillar 306-9380 Fuel Injector Replacement for C9 C7 Series Engine Diesel Parts new injector original new injector

The Caterpillar Fuel Injector 306-9380 / 3069380 is engineered as a direct OEM replacement for CAT C6, C6.4, and C6.6 series diesel engines widely deployed across excavators, wheel loaders, dozers, generator sets, and industrial power units. The component supports an output range of 120–220 HP and a displacement band of 4.4–6.6L, making it suitable for a broad spectrum of heavy equipment operating in construction, mining, agricultural, and marine auxiliary environments.

Manufactured with precision CNC-machined components, hardened steel internals, and a multi-hole nozzle design, the injector delivers high-pressure fuel atomization while withstanding elevated temperatures, sustained loads, and corrosive operating conditions. The corrosion- and wear-resistant materials extend service life, while the precision nozzle technology contributes to improved fuel economy, reduced emissions, and more efficient combustion. Every unit is tested for high-pressure and high-temperature performance to meet stringent OEM-grade benchmarks.

This injector also serves as a cross-reference for part numbers 10R-7225 and 326-6708, providing a reliable replacement option across CAT C6 platform variants. To maintain optimal performance, operators should follow recommended maintenance intervals including visual inspection every 250 hours, fuel system inspection every 500 hours, injector performance testing every 1000 hours, cleaning every 2000 hours, calibration checks every 4000 hours, and replacement evaluation at 6000 hours.
