Perkins original Perkins 10R-0961 C12 Fuel Injector Replacement for Perkins Excavator 345B II 365B L new injector original new injector

The Perkins C12 C10 3176C 3196 remanufactured diesel fuel injector 10R-0961 is engineered as a direct OE replacement for Perkins heavy-duty diesel engine platforms. It cross-references 10R0961, 212-3465, 2123465, 1165426, 116-5426, 2133465, 213-3465, EX630961, and 630961, ensuring broad compatibility across part inventories and simplifying the sourcing process for distributors, fleet operators, and diesel repair shops. Each unit is remanufactured to original equipment specifications, with precision fuel delivery calibration, stable atomization, and a heavy-duty construction designed to withstand demanding industrial operating conditions.

This injector is suitable for Perkins C10, C12, 3176C, and 3196 diesel engines, with proven application coverage on heavy trucks, industrial engines, agricultural equipment, Challenger tractors (65E, 75D, 75E, 85D, 85E, 95E), construction machinery, mining equipment, diesel generators, and industrial diesel power units. Every injector undergoes performance testing to verify injection quantity, spray pattern, leakage rate, and response, delivering consistent combustion performance and improved service efficiency for diesel repair operations. The remanufactured service option provides a cost-effective solution while maintaining OE-level reliability.

For reliable operation, use clean diesel fuel, replace fuel filters at recommended intervals, drain the water separator regularly, and control fuel contamination to prevent premature injector wear. Monitor engine oil for fuel dilution and inspect exhaust smoke during routine maintenance. Common failure symptoms include hard starting, rough idle, black smoke, white smoke, engine misfire, power loss, high fuel consumption, fuel knock, fuel in oil, and high exhaust temperature. Recommended diagnostic steps include checking fuel pressure, injector leakage, cylinder balance, spray quality, timing, compression, injector seals, and overall fuel system cleanliness. Single-injector or full-set replacement can be selected based on diagnostic results to restore engine performance.
