Caterpillar original Engine Common Rail Fuel Injector 147-0373 for C12 Excavator, Replacement for OEM 194-5080 10R-0960 212-3462 10R-0967 317-5278 20R-0055 153-7923 original new injector

The Caterpillar C12 Fuel Injector 147-0373 is an original equipment manufacturer component engineered for Caterpillar C12, C12 ACERT, industrial, generator, and marine diesel engines. Built to OEM manufacturing standards, this electronic unit injector delivers high-pressure fuel atomization, supporting improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions across demanding industrial operating environments.

Constructed with a hardened alloy steel body, corrosion-resistant coating, heat-treated internal components, and a wear-resistant nozzle assembly, the 147-0373 is designed for heavy-duty industrial use with high-temperature and high-pressure resistance. It provides stable idle performance, a long operational lifespan, and an extended service interval suitable for construction machinery, mining equipment, generator sets, marine power units, industrial engines, heavy trucks, and oil and gas equipment.

The injector cross-references with authorized part numbers including 0R-8773, 10R-0963, 10R-9235, 137-2500, 148-012-0008, 160-1090, 160-2303, 194-5083, 212-3463, EX630963, 630963, R10R0963, and FS10R0963. Installation requires clean fuel system procedures, replacement of seals and O-rings, verification of injector coding when applicable, and a pre-operation leak test. Operators should use clean diesel fuel, replace fuel filters regularly, avoid contaminated fuel, monitor fuel pressure, and check injector balance rates to ensure optimal long-term performance. Backed by a 12-month warranty.
