original 10R-1259 Common Rail Fuel Injector 212-3467 10R-0960 10R1259 for Excavator Diesel Parts Truck C10 C12 Engine original new injector

The 10R-1259 fuel injector is engineered specifically for the C10 engine series and remains fully interchangeable with compatible C12 engines. Designed for high-pressure common rail systems operating at 1500–1600 bar, this injector delivers precise atomization through multi-hole precision nozzles and electronically actuated control that supports fast response rates and accurate injection timing. The unit matches factory specifications for fit and function, integrating seamlessly with the standard electrical interface found on C10 and C12 platforms across construction, mining, generator, marine, and agricultural applications.

Manufactured with hardened alloy construction and protective coatings, the 10R-1259 resists wear, thermal stress, oxidation, and corrosive fuels commonly encountered in heavy-duty field operations. Premium seals and O-rings provide reliable environmental sealing to prevent leakage and contamination, while the thermal-stable design ensures consistent performance under elevated engine temperatures. Authorized OE numbers including 10R-1259, 387-9435, 328-2579, 293-4070, 241-9596, 573-4235, 212-3467, 317-5278, 350-7555, 10R-0967, and 0R-8773 confirm broad interchangeability with remanufactured and service replacement programs.

Proper installation requires 40–45 Nm torque, replacement of all seals and O-rings before fitting, and completion of OEM bleed procedures to purge air from the fuel system. Routine visual inspection every 250 hours, fuel system cleaning every 500 hours, and flow testing at factory-recommended intervals help maintain stable idle, improved fuel economy, lower emissions, and reduced downtime across demanding B2B operating environments.
