Perkins original  317-5279 Diesel Fuel Injector Pump 170-5252 203-3464 229-5918 0R-4987 187-6549 208-9160 for C12 Excavator original new injector

The Perkins C12 C10 common rail diesel fuel injector 317-5279 is engineered as a direct OE-style replacement for Perkins C12 and Perkins C10 diesel engines used in heavy-duty trucks, construction machinery, excavators, loaders, bulldozers, road machines, diesel generator sets, mining equipment, quarry machines, off-road diesel equipment, marine auxiliary engines, and industrial diesel power units. Compatibility must be confirmed by engine serial number and original injector part number, and related listings referencing Perkins 3176 and Perkins 3196 applications should also be verified before installation. The authorized primary OE number 317-5279 is fully supported by a wide cross-reference family for global search and inventory matching.

This injector assembly is cross-referenced with part numbers including 3175279, 229-5918, 2295918, 212-3462, 2123462, 10R-0961, 10R0961, 10R-0963, 10R0963, 10R-1258, 10R1258, 0R-4987, 0R4987, 0R-9530, 0R9530, 161-1785, 1611785, 166-0149, 1660149, 203-3464, 2033464, 212-3469, 2123469, 223-5328, 2235328, 10R-1003, 10R1003, 10R-1814, 10R1814, and FS10R1814, enabling distributors, fleet operators, and service workshops to source a single SKU that covers multiple legacy and current Perkins injector references. The unit is built with OEM-style fitment, precision fuel delivery, stable atomization, and heavy-duty construction, and each injector is professionally tested for flow rate, leakage, spray pattern, solenoid response, and overall performance.

Routine maintenance includes using clean diesel fuel, replacing fuel filters at the recommended interval, draining the water separator, checking injector balance, diagnosing hard starting, black smoke, and excessive return flow, and inspecting injectors during engine overhaul, cylinder head repair, and fuel system service. Installation requires confirming the injector number and engine serial number, cleaning the injector bore, replacing all seals and O-rings, inspecting the fuel system, lubricating seals, avoiding nozzle damage, tightening to the official service manual torque specification, priming the fuel system, and testing for leaks, smoke, misfire, rough idle, and diagnostic fault codes before returning the engine to service.
