Caterpillar original Common Rail Diesel Fuel Injector 10R-0961 For C11 C13 C10 3176C Excavator, Replacement for 212-3463 10R-9235 212-3465 original new injector

The Caterpillar CAT reman fuel injector 10R-0961 / 212-3465 is an original-type remanufactured diesel fuel nozzle and injector assembly engineered for Caterpillar C10, C12, 3176, 3176B, 3176C, and 3196 heavy-duty diesel engines. It is also referenced in supplier search groups for the C11/C12/C13 injector family, including cross-listed numbers such as 20R-2437, 212-3462, 212-3463, 10R-1258, 250-1309, 259-5409, 10R-1274, 10R-7236, 10R-2977, 10R-3258, and 10R-6162; however, C13 application must be confirmed by engine serial number and original injector data prior to ordering.

Built with critical engineering updates, coated plungers for improved wear resistance, and extensive reliability testing, this reman injector is remanufactured to perform with low-sulfur, low-lubricity diesel fuel. Precision fuel metering helps restore engine power, combustion balance, and throttle response, while the optimized spray pattern supports cleaner combustion and reduced smoke when the fuel system is properly maintained. Wear-resistant internal components make it well suited to heavy-duty diesel operating cycles in construction machinery, industrial power units, generator sets, marine engines, agricultural tractors such as the Challenger 65E, 75D, 75E, 85D, 85E, and 95E, and heavy-duty trucks — subject to verification by engine model, engine serial number, and original injector number.

The part is searchable under multiple number formats, including 10R-0961, 10R0961, 212-3465, and 2123465, supporting global parts distribution, industrial engine repair, machinery maintenance, and fleet service operations.
