original 10R-8502 Diesel Fuel Injector Common Rail Injector for C15 C16 Excavator E365C E374D Engine Replacement for OEM 211-3023 211-3024 253-0617 original new injector

Engineered as an OE-style direct replacement, the 10R-8502 Electronic Unit Injector supports C15, 3406E, and C16 heavy-duty diesel engines used across highway trucks, long-haul tractors, vocational fleets, construction machinery, mining equipment, oilfield service units, marine auxiliary power, generator sets, and agricultural heavy equipment. Compatible with engine serial number prefixes 1LW, 2WS, 5EK, 6NZ, 6TS, and MBN, this injector covers 1995–2003 3406E/C15/C16 applications and cross-references major OE numbers including 10R-0958, 10R-2780, 0R-4893, 0R-4118, 0R-4668, 117-1148, 118-9035, 152-3680, 191-3004, 211-3024, and EX630958.

Built for precision fuel delivery, the EUI design provides accurate fuel metering, correct injection timing, high-pressure atomization, balanced cylinder distribution, reliable sealing, and fast solenoid response. Durable metal construction and flow-matched set availability support stable power output, efficient combustion, reduced smoke, smoother idle, lower vibration, better cold starting, and improved acceleration under load. Every injector is 100% tested before shipment for fuel delivery, leakage, injector response, atomization, solenoid performance, electrical resistance, and flow balance to ensure consistent field performance.

For optimal service life, confirm part number, engine model, ESN prefix, and old injector number before installation. Clean the fuel system and injector bore, install correct O-rings, seals, and copper washers, lightly lubricate with clean engine oil, and torque to service manual values. Complete injector trim code entry or ECM calibration if required and prime the fuel system before starting.
