The Caterpillar 3412 fuel injector 10R-1267 is engineered as a direct OEM and aftermarket replacement for CAT 3412, 3412C, and 3412E V12 diesel engines. Constructed from high-strength steel and precision alloys, this injector delivers consistent fuel flow, accurate spray atomization, and long-term durability under extreme industrial, marine, and generator operating conditions. With an operating pressure range of 2200–2500 bar and compatibility with both mechanical and electronic fuel systems, it meets OEM Caterpillar pressure, timing, and performance specifications.

Designed for global heavy-duty applications, the 10R-1267 injector supports CAT 3412G industrial generator sets, 3412 marine engines, CAT 3400 series excavators, and CAT 3450 mining loaders. Its multi-hole nozzle design ensures fine fuel atomization for improved combustion efficiency, while precision machining maintains stable injection rates over extended service intervals. The injector is built to resist wear, corrosion, and high-temperature environments, making it a reliable solution for mining, construction, oil and gas, and power generation operations.

Installation requires clean cylinder head surfaces, pre-lubrication with clean diesel, and adherence to OEM torque settings of 35–40 Nm. Routine inspection every 500 operating hours, combined with clean fuel filtration and avoidance of low-quality diesel, helps maximize injector lifespan. Backed by a 12-month industrial warranty, the 10R-1267 provides a dependable replacement solution for maintaining CAT 3412 engine performance in demanding field conditions.
