original 212-3465 10R-0961 350-7555 Diesel Engine Fuel Injector For Excavator C12 original new injector

Engineered for demanding heavy-duty diesel service, the 212-3465 Electronic Unit Injector (EUI) is a precision fuel delivery component designed for C12, C10, 3176, 3176C, and 3196 diesel engines. Supplied as an original replacement or fully remanufactured unit, this injector supports accurate fuel metering, electronic injection control, stable spray pattern formation, and reliable operation under sustained heavy-duty load conditions. It is fully compatible with modern low-sulfur, low-lubricity diesel fuels, making it a versatile solution for fleet operators, engine rebuilders, and industrial maintenance teams.

The 212-3465 injector cross-references a wide range of common numbers, including 10R-0961, 0R-7549, 166-0155, 116-5426, EX630961, 630961, CA2123465, CA10R0961, CA0R7549, and CA1660155, providing broad sourcing flexibility. Each remanufactured unit undergoes a controlled restoration process that includes critical component lapping, new nozzle installation, solenoid replacement, spring and shim renewal, check-ball replacement, and 100% O-ring replacement. Professional bench testing covers flow testing, solenoid response, resistance measurement, leak testing, and spray pattern inspection to confirm performance parity with OE specifications.

Typical applications include Challenger 65E, 75D, 75E, 85D, 85E, and 95E tractors, Combine 480, on-highway trucks, agricultural machinery, mining equipment, construction fleets, and stationary generator sets. Correct installation—confirming engine serial number and arrangement, cleaning the injector bore, renewing seals, and following official torque procedures—ensures long service life and stable engine performance.
