original Common Rail Fuel Injector 317-5278, 350-7555, 10R-0960 10R-1259 Replacement for OEM Parts, for C10 C12 Engine, Excavator 345B 345C CPT372 Truck Diesel Parts original new injector

Engineered for the demanding duty cycles of heavy-duty diesel machinery, the erpillar 10R-1259 common rail fuel injector is a precision injection component built to OEM specifiions for the C10 engine family and compatible C12 series. Operating within high-pressure common rail systems at 1500–1600 bar, it responds to electronically timed ECU signals to deliver accurately metered fuel into the combustion chamber. Multi-hole precision nozzles generate a finely atomized spray pattern, promoting efficient fuel-air mixing, stable torque output, lower emissions, and optimized fuel consumption under continuous heavy-load operation.

Constructed from hardened high-strength alloys with corrosion-resistant coatings, the injector resists wear, oxidation, and thermal stress in harsh industrial environments. Precision machining guarantees repeatable injection performance and consistent atomization over extended service intervals, while the standard erpillar electrical interface ensures seamless integration with factory engine management systems. Every unit is manufactured to OEM dimensional and performance standards, delivering dependable sealing and correct fitment when specified installation torque values are followed.

aloged under OE numbers 10R-1259 and 10R1259, with cross references 387-9435, 328-2579, 293-4070, 241-9596, and 573-4235, plus related codes 317-5278, 350-7555, 10R-0967, and 0R-8773, this injector simplifies global sourcing for distributors and service centers. Typical appliions include 345B/345C excavators, CPT372 trucks, bulldozers, loaders, mining trucks, generator sets, marine auxiliary engines, and agricultural tractors. Engine serial number verifiion is recommended before installation.
