Perkins original Perkins 317-5278 Fuel Injector for C11 C13 Diesel Engine Excavator Spare Part 212-3463 212-3462 new injector original new injector

The 317-5278 diesel fuel injector is engineered as a direct OE-style replacement for Perkins C13, C12, C11, C10, and 3176C diesel engines, with the C13 platform serving as the primary application target. Built to original equipment specifications, this common rail injector delivers precise fuel metering and fine atomization, supporting stable combustion and balanced cylinder performance across demanding operating cycles. It is fully compatible with motor graders 14H, 140H, 143H, 160H, 163H, wheel dozer 814F, compactors 815F and 816F, wheel loader 966G II, pipelayer 572R II, and tractor D7R II used in construction, mining, road building, and earthmoving applications.

This injector carries the authorized reference identifiers 317-5278, 3175278, CA3175278, 3176C, and 23670-E0510, allowing distributors, fleet operators, and service workshops to perform straightforward part number searches, accurate cross-referencing, and reliable stock identification. The unit is individually factory-tested to verify spray pattern, opening pressure, and flow rate, ensuring drop-in installation and consistent engine response. Heavy-duty internal components withstand high injection pressures and prolonged duty cycles typical of industrial machinery environments.

For optimal service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and keep the fuel tank free of contamination. Routine diagnostic inspection is recommended when symptoms such as hard starting, rough idle, black or white smoke, reduced power, elevated fuel consumption, engine knock, misfire, or fuel dilution in engine oil appear. Authorized OE references and standardized cross numbers simplify procurement, technical verification, and warranty support for global B2B buyers and aftermarket channels.
