Caterpillar original 240-8063 Fuel Injector Common Rail Diesel Injector for C7 C9 Engine 330D 336D Excavator Replacement for OEM new injector original new injector

The Caterpillar CAT C9 Fuel Injector 240-8063 is an OEM-quality replacement component engineered for the Caterpillar C9 diesel engine platform. Designed with advanced machining technology, this injector delivers high-precision fuel metering and superior atomization through an optimized micro-nozzle configuration, ensuring improved fuel efficiency, power output, and combustion completeness across demanding operating conditions.

Manufactured using hardened alloy steel and wear-resistant materials, the 240-8063 injector assembly is built to withstand continuous severe-duty operation, high temperatures, and corrosive environments. Anti-corrosion treatment makes it well suited for marine engines, generator sets, and humid industrial applications. The component maintains stable injection pressure and optimized spray patterns, directly contributing to better emission control and long service life.

The injector is compatible with CAT 330D and 336D excavators, 966H and 972H wheel loaders, 140M motor graders, C9 generator sets, marine propulsion engines, and broad industrial power units. It cross-references with 10R-4761 and 387-9433, allowing flexible interchangeability for fleet maintenance. Recommended preventive practices include the use of clean diesel fuel, regular fuel filter replacement, avoidance of water contamination, periodic injector balance testing, and adherence to OEM torque specifications during installation to ensure reliable long-term performance.
