Caterpillar original Caterpillar 10R-1288 Fuel Injector 20R-1270 392-0206 for 3508 3512 3516 Diesel Engine PM3508B PM3516B new injector original new injector

The Caterpillar 10R-1288 fuel injector is engineered for heavy-duty CAT 3500 Series diesel engines, including the 3512B, 3512C, 3516B, 3508B, and 3508C platforms manufactured between 2000 and 2026. Designed to operate within a high-pressure fuel system ranging from 1600 to 2000 bar, this injector delivers precise atomization and consistent fuel delivery across 8 to 16 cylinder configurations. As a direct replacement component, it meets OEM standard calibration and torque specifications of 40–45 Nm, ensuring reliable integration with existing fuel rail assemblies.

This industrial-grade injector supports a wide range of demanding applications, from CAT 3512B generator sets and commercial marine propulsion systems to mining haul trucks, excavators, construction dozers, oil and gas compressors, and stationary industrial power units. It is fully interchangeable with authorized cross-reference numbers 0R8685, 0R9348, 126-2081, 127-8216, and 392-0201, providing flexibility for OEM replacement, remanufactured engine programs, and aftermarket servicing operations.

Built to reduce emissions, optimize combustion efficiency, and extend engine service life, the 10R-1288 injector requires pre-installation cleaning and follows scheduled maintenance intervals including fuel filter replacement at 250 hours, injector inspection at 1000 hours, and performance testing during major overhauls. Regular fuel analysis and spray pattern checks ensure sustained performance in the most severe operating environments.
