original Diesel Nozzle Assembly 10R-0968 1660155 Fuel Injector for C10 C12 345C Excavator Replacement for OEM new injector original new injector

Engineered specifically for C12 diesel platforms, the 10R-0968 remanufactured electronic unit injector delivers OEM-equivalent fuel metering, atomization, and injection timing across the full operating range. Direct fitment is confirmed for C10 and C12 engines, with additional cross coverage extending to 3176C and 3196 engine applications commonly used in heavy-duty industrial equipment. Authorized cross references include EX630968, 0R4988, 116-5425, 156-1011, 212-3466, and 716323AT, allowing distributors, fleet operators, and rebuild shops to consolidate part numbers into a single validated SKU.

The injector is built as a genuine remanufactured component calibrated for modern low-sulfur and lower-lubricity diesel fuels, supporting compliance with current emission and engine durability standards. Heavy-duty solenoid construction, precision-machined nozzle components, and controlled spray geometry ensure stable cylinder pressure, balanced combustion, and predictable cold-start behavior. The part is intended for B2B distribution channels serving heavy trucks, construction machinery, mining equipment, marine propulsion, diesel generator sets, agricultural power units, and large-scale engine remanufacturing programs.

Routine maintenance of the injection system is essential to protect long-term injector performance. Operators are advised to replace fuel filters on schedule, drain the water separator, inspect injector harness and electrical connections, perform periodic cylinder balance and injector cutout tests, and monitor return-line leakage, exhaust smoke color, and oil analysis results for fuel dilution. Preventive replacement during major engine overhauls is recommended for high-hour C12 fleets. Clean fuel and correct filtration remain the most effective measures to maximize injector service life and reduce unscheduled downtime.
