Reliable combustion in a heavy-duty diesel engine starts at the injector, and the Caterpillar 9Y-0052 fuel injector is engineered to deliver exactly that. Designed for the CAT 3500 Series engine family, this mechanical diesel fuel injector is fully compatible with Caterpillar 3512, 3512A, and 3512B engines, including marine, generator, offshore, industrial, and mining configurations. As a genuine replacement for OE number 9Y-0052 / 9Y0052 with cross reference 0R-2503 / 0R2503, it simplifies sourcing for distributors and fleet operators.
Manufactured to OEM specifications from high-strength alloy steel, the injector meters and atomizes diesel fuel into the combustion chamber at the correct pressure, timing, and spray pattern. This precision delivers improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, and consistent engine power output. Its heavy-duty construction, corrosion-resistant design, and excellent thermal stability ensure a long operating lifespan, even under continuous-load generator operation, demanding marine duty cycles, and high-horsepower industrial service.
The 9Y-0052 installs directly into the cylinder head fuel system with new sealing components, following Caterpillar torque specifications and standard priming and leak-inspection procedures. To protect service life, operators should use clean diesel fuel, replace fuel filters regularly, and monitor exhaust smoke and fuel consumption—early indicators of issues such as black smoke from excess fuel injection, white smoke from incomplete combustion, engine knock, or hard starting. Warranty support is available, with supply to export markets worldwide.
