Caterpillar original 10R-0725 EUI Fuel Injector for C12 C10 Engine, Diesel Engine Spare Part, Excavator Truck, Replacement for OEM original new injector

The CAT 10R-0725 remanufactured diesel fuel injector is engineered for Caterpillar C12, C10, 3176, 3176C, and 3196 engines used across heavy-duty trucks, industrial machinery, marine applications, and stationary generator sets. Built as a direct OE replacement, it integrates with high-pressure unit injection systems to deliver precise fuel metering, controlled atomization, and stable cylinder-to-cylinder delivery, supporting combustion efficiency and consistent idle quality across demanding duty cycles.

Each injector is produced through a controlled reman process that includes complete disassembly, cleaning, nozzle inspection, leak testing, flow testing, and replacement of worn internal components. Corrosion-resistant materials and precision-machined sealing surfaces help ensure strong sealing performance, predictable spray patterns, and reliable combustion under elevated injection pressures. The injector supports engine power recovery, fuel economy restoration, and reduced exhaust smoke, while maintaining compatibility with widely used cross references such as 212-3464, 166-0153, EX630725, CA2123464, CA1660153, CA10R0725, CH12082, 212-3462, 161-1785, 116-5414, 10R-0967, 10R-1258, 249-0707, 317-5278, and 874-822.

For distributors, fleet operators, and service workshops, the 10R-0725 injector covers broad market demand, fitting Freightliner, Sterling, Peterbilt, and Western Star platforms alongside construction, marine, and industrial equipment. Best results are achieved by using clean diesel, replacing fuel filters on schedule, draining water separators, and inspecting related cylinders when one injector fails. Recommended diagnostics include leakage test, fuel pressure test, return flow test, cylinder cut-out test, spray pattern test, electrical resistance inspection, and engine serial number verification before installation.
