Caterpillar original Caterpillar 11R-0680 diesel fuel injector assembly replacement for OEM C12 C15 engine model new injector original new injector

The Caterpillar 11R-0680 fuel injector is engineered as a direct OEM replacement for the CAT 3512B V12 diesel engine platform, serving marine propulsion, generator set, mining, oil and gas, and industrial power unit applications. Manufactured to original equipment specifications, this injector assembly delivers precise fuel metering and consistent spray patterns required for stable combustion across a wide range of heavy-duty operating environments including offshore platforms, standby power systems, and continuous-duty industrial plants.

Built with high-grade hardened components and corrosion-resistant materials, the 11R-0680 injector withstands elevated cylinder pressures, prolonged high-load cycles, and exposure to contaminated fuel conditions. Its precision-machined nozzle tip promotes superior fuel atomization, which directly contributes to improved fuel economy, reduced exhaust emissions, and reliable cold-start performance. The robust internal solenoid and sealing assembly ensure accurate injection timing and long-term durability, even under the demanding thermal and mechanical stresses of continuous marine or generator operation.

This unit is also cross-referenced with 10R-0955 and 0R-8686, providing flexible interchangeability for fleet maintenance, engine overhauls, and field replacement scenarios. Routine best practices such as using premium diesel fuel, regular fuel filter replacement, scheduled injector diagnostics, and monitoring of exhaust emissions will help maximize service life and maintain optimal engine performance. The 11R-0680 is a trusted solution for operators seeking OEM-grade reliability for Caterpillar 3512B powered equipment.
