original 20R-8062 Fuel Injector Assembly 328-2578 387-9433 20R-8063 for C9 330D 336D Excavator Auto Parts Replacement for OEM new original new injector

The 20R-8062 fuel injector is precision-engineered specifically for the C9 diesel engine platform, delivering OEM equivalent performance across a wide range of heavy-duty applications. As an electronically controlled high-pressure common rail injector, it ensures accurate fuel metering, optimized spray atomization, and stable combustion performance. The injector is built with advanced machining technology, precision nozzle calibration, and high-strength alloy materials, all manufactured under stringent quality control standards to guarantee long operating life and reliable operation under extreme working conditions.

Designed to match the technical specifications of the C9 engine series—including its 8.8-liter displacement, inline 6-cylinder configuration, turbocharged aspiration, water-cooled system, and ACERT emission technology—this injector supports improved fuel economy, increased equipment productivity, and reduced maintenance costs. It is fully compatible with -powered machinery such as the 330D and 336D excavators, 966H and 972H wheel loaders, 140M motor graders, generator sets, marine propulsion systems, mining equipment, industrial power units, and oil & gas field equipment. Cross-referenced with part numbers 326-1641 and 3261641, it provides a dependable replacement solution for fleet operators and service technicians.

Proper maintenance practices significantly extend injector service life. Operators should use ultra-clean diesel fuel, replace fuel filters at recommended intervals, and prevent water contamination within the fuel system. Routine monitoring of injector return flow and fuel pressure helps detect early signs of performance degradation. For accurate troubleshooting, advanced diagnostic methods—including electronic scan tool analysis, cylinder cutout testing, injector return flow measurement, fuel pressure analysis, combustion performance monitoring, ECM fault code analysis, and injector bench testing—are recommended to ensure precise fault identification and maintain peak engine efficiency.
