original 170-5252 Diesel Engine Fuel Injector 208-9160 317-5279 212-3464 194-5083 20R-0055 0R-9530 for Excavator Truck original new injector

Engineered exclusively for the C12 diesel platform, the 170-5252 fuel injector delivers factory-matched fuel delivery characteristics across truck, marine, generator, and industrial configurations. As an electronic unit injector (EUI), it integrates seamlessly with the C12 engine control module, maintaining precise injection timing and pressure parameters specific to the C12 combustion cycle. The component is manufactured to OEM dimensional and performance specifications, ensuring direct fitment into the C12 cylinder head without modification, and full compatibility with the engine's existing fuel rail, wiring harness, and ECU calibration.

Constructed from high-grade alloy steel and corrosion-resistant internal components, the 170-5252 injector is built to withstand the demanding operating conditions encountered in heavy-duty C12 applications, including long-haul trucking, offshore marine propulsion, continuous-duty generator sets, and rugged construction or mining environments. Precision-machined nozzle orifices provide enhanced atomization efficiency, promoting optimal combustion, reduced exhaust emissions, and improved fuel economy. Stable injection pressure output and consistent spray pattern geometry help preserve cylinder pressure balance, extend service intervals, and protect downstream aftertreatment components across the full C12 engine lifespan.

Routine maintenance safeguards injector longevity: operators should use high-quality filtered diesel, replace fuel filters at recommended intervals, monitor fuel rail pressure, and avoid contaminated fuel sources. During installation, technicians must thoroughly clean the injector bore, inspect all fuel lines, replace sealing washers and O-rings, apply manufacturer-specified torque values, bleed the fuel system completely, and perform a diagnostic verification cycle to confirm leak-free operation. Authorized cross references include 10R-0955, 0R-8479, and CAT1705252, all validated against the C12 engine family.
