Caterpillar original Common Rail Diesel Fuel Injector 7C-9576 7E2269 for Caterpillar 3512 3516 3508 Gen Set Engine, Replacement for OEM 0R-1756, 0R-1758 original new injector

Procurement and maintenance teams servicing Caterpillar 3500-series heavy-duty diesel engines can rely on the genuine CAT 7C-9576 mechanical fuel injector as a precision-engineered original equipment component. Built for the 3512A engine platform, it adheres to industrial-grade precision machining standards to deliver accurate fuel metering, optimized atomization and synchronized injection timing, supporting stable combustion, lower fuel consumption, reduced smoke emissions and consistent power output across extreme operating conditions. It is engineered for power generation, marine propulsion, mining, oilfield and heavy industrial use cases.

The 7C-9576 injector is compatible with a broad range of CAT 3500-series engines, including 3512A, 3512, 3508, 3508B, 3516 and 3516B. It comes with a complete cross-reference database covering alternative part numbers, universal interchange numbers and remanufactured reference numbers widely used across global Caterpillar aftermarket, remanufacturing and independent diesel injection networks, eliminating procurement mismatches and simplifying inventory management for international spare parts sourcing.

This heavy-duty injector features high injection accuracy, long service life, stable fuel delivery and excellent cold-start performance, with OEM-equivalent performance and global market acceptance to support continuous operation. Following recommended installation practices (including seal replacement, bore cleaning and calibrated torque application) and preventive maintenance schedules (regular injector testing, fuel filter replacement and emission monitoring) helps extend engine service life and reduce unplanned downtime for industrial operators.
