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

Engineered for Perkins C10, C12, 3176C, and 3196 diesel platforms, the 10R-0961 remanufactured fuel injector delivers precise fuel metering and consistent atomization to support clean combustion and stable idling. It is cross-referenced with 212-3465, 1165426, 2133465, EX630961, and 630961, allowing broad coverage for heavy trucks, construction machinery, mining equipment, agricultural machinery, Challenger tractor series, and industrial diesel generator sets operating on Perkins Reman Fuel System configurations.

Each unit is disassembled, cleaned, and rebuilt with heavy-duty components before being calibrated and performance tested to meet OE flow rate, spray pattern, and back-leak specifications. This reman process reduces overall repair cost while maintaining reliable cold-start response, balanced cylinder output, and reduced exhaust smoke. The injector's broad cross-reference coverage simplifies inventory management for distributors, fleet workshops, and industrial service operations handling mixed Perkins engine populations.

Routine maintenance is straightforward: use clean diesel fuel, replace fuel filters at recommended intervals, drain the water separator, and monitor engine oil for fuel dilution. When symptoms such as hard starting, rough idle, power loss, black or white smoke, misfire, or elevated fuel consumption appear, technicians should verify fuel pressure, check injector leakage, perform cylinder balance and spray quality tests, and replace individual units or the full set based on diagnostic results. Correct storage of spare injectors and prompt replacement of damaged seals help maximize service life and maintain efficient diesel engine operation.
