original 363-0493 Common Rail Fuel Injector 3630493 20R-5036 367-4293 456-3588 for C9 C9.3 336E 336EL 336ELN Excavator Diesel Engine Injector original new injector

Engineered for demanding heavy-duty applications, this C9.3 common rail diesel fuel injector (OE 363-0493) delivers precise fuel metering and optimized spray atomization to maximize combustion efficiency across a wide range of industrial platforms. Manufactured to meet OEM specifications, it operates reliably at common rail pressures up to 2200 bar under electronic solenoid control, ensuring consistent injection timing, reduced fuel consumption, and lower exhaust emissions in critical duty cycles.

This injector is fully cross-referenced with 456-3493, 20R-5036, 20R-1318, 367-4293, 364-8024, 171-9704, and 196-1401, providing a direct replacement solution for C9.3, C9.3 ACERT, C9.3B, Marine C9.3, and Generator C9.3 engines. It is compatible with 336E and 336F excavators, 966K and 972K wheel loaders, D6T and D7E track-type tractors, 140M and 160M motor graders, and 568 FM forestry machines, as well as stationary generator sets. Typical industries served include construction, mining, forestry, power generation, marine propulsion, oil & gas, and large-scale agricultural machinery.

Benefits include precise fuel quantity control, increased horsepower, enhanced engine durability, and improved fuel economy. Recommended maintenance includes inspection every 500 operating hours, fuel filter replacement each service interval, injector balance testing every 2,000 hours, and full fuel system cleaning at major service. Proper maintenance reduces downtime, lowers operating cost, and extends injector service life for fleet operators.
