Perkins original Perkins 306-9390 Fuel Injector C6.6 for Wheel Loader 928HZ 938H Replacement for OEM 2645A749 10R7673 292-3790 new injector original new injector

The Perkins 306-9390 fuel injector is engineered as a direct OEM equivalent replacement for Perkins C6, C6.4, and C6.6 diesel engines deployed across excavators, wheel loaders, motor graders, generator sets, and marine auxiliary power units. It also cross-references with additional part numbers 10R-7674, 320-0690, 310-9067, 306-9380, 292-3780, 292-3790, 320-0688, 321-0990, 321-3600, 382-0480, 2645A749, 2645A751, 2645A734, 2645A735, and 2645A719, allowing broad interchangeability for fleet operators and maintenance workshops managing mixed Perkins-powered equipment.

Manufactured to original equipment standards, this common rail injector features precision flow calibration, a superior spray pattern, low leakage design, and high-pressure durability for consistent fuel delivery across demanding duty cycles. Enhanced atomization supports improved cold-start performance, higher combustion efficiency, lower fuel consumption, reduced particulate emissions, and extended engine service life—critical for heavy-load construction, mining, power generation, and industrial applications.

Routine maintenance includes timely fuel filter replacement, use of premium diesel fuel, prevention of water contamination, periodic injector performance testing, and preventive fuel system servicing. This injector effectively resolves common symptoms such as hard starting, rough idle, excessive smoke, engine misfire, reduced power output, increased fuel consumption, and excessive emissions, restoring reliable engine performance.
