For fleets, equipment operators and maintenance providers serving heavy-duty industrial sectors, the Caterpillar 0R-8680 fuel injector is a purpose-built replacement component for CAT 3512A and other qualified 3500 Series diesel engines. It is compatible with a wide range of verified engine models including 3512, 3512B, 3516, 3516B, 3508, 3508B and 3516C (pending serial number confirmation), and supports critical equipment across power generation, marine propulsion, mining, oilfield and industrial power system use cases. As a high-demand fuel system part, it is engineered to match original equipment performance requirements for consistent field operation.

Manufactured to strict OEM specifications with high-strength alloy steel, this mechanical fuel injector features a precision-machined nozzle and optimized spray pattern to deliver accurate fuel metering and superior atomization. These design features support complete combustion, improved fuel efficiency, reduced emissions and stable injection timing, while high-pressure-resistant, corrosion-resistant and wear-resistant construction extends service life, lowers long-term maintenance costs and withstands continuous heavy-duty operating conditions including harsh marine and mining environments.

The 0R-8680 injector is available in new, OEM equivalent and remanufactured conditions to suit varied budget and operational needs. All units meet ISO quality standards, ship in export-standard packaging, and come with a 12-month warranty for verified applications. It supports direct-fit installation, with leak testing and professional calibration recommended per Caterpillar service protocols to ensure reliable long-term performance.
