original 20R-8062 Diesel Fuel Injector Assembly for C7 C9 C-9 Engine 330D 336D Excavator Injector GP 387-9433 387-9434 387-9436 387-9437 10R-4844 original new injector

Engineered for demanding industrial service, the 20R-8062 common rail fuel injector is a precision component designed for the C9 ACERT 8.8-liter inline six-cylinder turbocharged diesel engine platform. Cross-referenced with 20R8062, 326-1641, and 3261641, this injector delivers OEM-equivalent metering accuracy, optimized spray atomization, and stable combustion characteristics required by heavy-duty construction, mining, marine, and power generation equipment operating under continuous load.

Manufactured with advanced machining technology, precision nozzle calibration, and high-strength alloy materials, the 20R-8062 supports improved combustion efficiency, reduced fuel consumption, increased horsepower output, lower exhaust emissions, enhanced throttle response, stable idle performance, and reliable cold starting. It is a direct fit for 330D and 336D excavators, 966H and 972H wheel loaders, 140M motor graders, prime and standby generator sets, work boats, and offshore industrial power units, providing operators with long operating life, reduced downtime, and lower total maintenance cost.

Installation follows standard OEM procedures: relieve fuel pressure, remove the existing injector, clean the cylinder head seat, fit new sealing components, torque to specification, prime the system, and perform leak and performance verification. Recommended diagnostic methods include electronic scan tool analysis, cylinder cutout testing, injector return flow measurement, fuel pressure analysis, and ECM fault code review. Buyers should confirm compatibility using engine serial number (ESN) and equipment PIN prior to ordering.
