original 20R-8063 Common Rail Diesel Fuel Injector Nozzle for C9 Engine D6R D6R III D6T D7R D7R LGP Dozer Excavator Replacement 387-9434 267-9715 3282573 original new injector

Engineered for demanding heavy-duty applications, the 20R-8063 fuel injector delivers precision-controlled diesel atomization for C9 and C9 ACERT engine platforms. This common rail injector assembly is manufactured to OEM tolerances and serves as a direct replacement for cross numbers 10R-7675 and 328-2577, providing a dependable fuel system solution for excavators, wheel loaders, generator sets, marine propulsion units, and industrial power modules operating under continuous load.

The 20R-8063 injector incorporates hardened internal components, corrosion-resistant materials, and precision nozzle technology to withstand high-pressure common rail operating conditions. Each unit is flow-calibrated to ensure consistent fuel delivery across all cylinders, resulting in improved combustion efficiency, reduced fuel consumption, lower particulate emissions, and higher engine power output. Additional engineering benefits include enhanced cold-start performance, stable idle operation, and long service intervals suitable for 330D and 336D excavators, 973D loaders, mining support equipment, workboats, pump drives, compressor systems, and agricultural machinery.

Recommended maintenance includes fuel filter replacement every 250-500 hours, injector inspection every 1000 hours, fuel system cleaning every 2000 hours, and full injector testing every 3000 hours. Proper installation requires cleaning the fuel system, replacing seals and washers, following torque specifications, conducting leak testing, and verifying ECM diagnostics. Common troubleshooting indicators such as hard starting, black smoke, power loss, rough idle, and engine misfire can be traced to injector leakage, poor atomization, restricted delivery, or component wear.
