original 456-3509 Diesel Common Rail Fuel Injector Assembly for C9.3 Engine D6T D7E E336E E336F Excavator Bulldozer 20R-5075 4563509 Injection Valve original new injector

Engineered as a direct OEM-equivalent replacement, the 456-3509 Fuel Injector is purpose-built for C9.3 series diesel engines operating in demanding construction, mining, industrial, marine, and power generation environments. Manufactured from high strength alloy steel with precision machined nozzle geometry, this common rail injector delivers OEM dimensional accuracy, optimized spray patterns, and stable high-pressure atomization to meet the performance expectations of heavy-duty fleet operators and industrial buyers worldwide.

The injector is fully compatible with C9.3, C9.3 ACERT, C9.3B, and C9.3 Industrial, Construction, and Generator engine variants, supporting equipment such as the 336 and 340 Excavators, 966 and 972 Wheel Loaders, 140 Motor Grader, generator sets, and power units. Cross references include 456-3509 and 4563509. Buyers are advised to verify final compatibility using the engine serial number (ESN) and machine serial number (PIN) before installation. Global demand is served across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia.

Key benefits include improved fuel atomization, higher combustion efficiency, increased engine power, reduced fuel consumption, lower emissions, and enhanced engine durability. Recommended best practices cover ultra-clean diesel fuel usage, regular filter replacement, and correct torque during installation. Diagnostic support addresses hard starting, black smoke, and power loss through injector flow, leakage, and balance testing procedures.
