original Excavator Parts 1OR-1814 Fuel Injector for C12 C11 C13 Diesel Engine Replacement for OEM 147-0373 212-3462 317-5278 20R-0055 new original new injector

The 1OR-1814 electronic unit injector is engineered as a direct-fit replacement for the C12 diesel engine, delivering precise fuel metering and consistent injection pressure across demanding industrial operating conditions. Built to OEM manufacturing standards, this injector integrates seamlessly with the factory electronic fuel control system of the C12 platform, ensuring stable cold-start performance, balanced cylinder delivery, and optimized combustion efficiency for generator sets, construction machinery, mining equipment, marine propulsion, and heavy-duty truck applications.

Featuring a precision-machined nozzle and high-pressure delivery assembly, the 1OR-1814 injector provides reliable atomization and long service life under continuous heavy-load operation. Its electronic control design enables accurate fuel quantity adjustment in coordination with the engine management system, supporting reduced exhaust emissions and improved fuel economy. The unit is interchangeable with multiple cross-reference numbers including 10R-1814, 229-5918, 194-5083, 212-3463, 9X7317, 9295918, 1198784, 2153198, and EX630963, allowing flexible substitution across C12-powered equipment fleets and simplifying spare parts inventory management for distributors and service operations.

Routine maintenance recommendations include the use of premium-grade diesel fuel, regular replacement of fuel filtration elements, and periodic injector balance rate testing to sustain peak performance. Operators should monitor for symptoms such as hard starting, excessive smoke, rough idle, power loss, or elevated fuel consumption, as these may indicate injector wear, poor atomization, fuel restriction, internal leakage, or electronic failure requiring timely service intervention.
