For CAT 3500 series engines operating in marine, power generation, mining, and oilfield service, reliable fuel injection is non-negotiable. The Caterpillar 6I-3075 fuel injector (OE 6I3075) is an OEM-quality diesel injector assembly built for these demanding platforms, covering the 3512A, 3512, and 3516 engines used in generator sets, marine propulsion systems, mining trucks, oilfield power units, and other heavy-duty industrial equipment.

As a core component of the engine fuel injection system, this injector delivers diesel fuel into the combustion chamber in a finely atomized spray, supporting efficient combustion, stable power output, and smooth engine operation. Manufactured to original equipment standards, the 6I-3075 provides precise fitment and consistent performance under the continuous, high-load conditions typical of power generation, marine, and off-highway service, helping to maintain engine reliability and reduce unplanned downtime across the 3500 series engine family.

This injector cross-references multiple industry part numbers, including 0R-8680, 0R8680, OR-8680, OR8680, 7C-9795, 7C-4184, and NSN 2815-01-430-3140, with 0R-8680 serving as the remanufactured alternative. This broad interchange coverage simplifies parts identification and procurement for fleet operators, maintenance providers, and equipment dealers. For distributors and B2B buyers sourcing CAT 3512A fuel system components, the 6I-3075 offers a dependable, OEM-standard replacement solution with full cross-reference traceability.
