Caterpillar 10R-1284 / 10R1284 Fuel Injector for 3512B Engine
Industrial Product Overview
The Caterpillar 10R-1284, commonly written as 10R1284, is a heavy-duty diesel fuel injector assembly associated with Caterpillar 3512B-series engine applications.
Designed for demanding industrial diesel operating environments, this injector is used as part of the engine fuel delivery and combustion system, where accurate fuel metering, injection timing, atomization quality, and consistent cylinder-to-cylinder fuel delivery are critical to engine performance.
The 3512B engine platform is widely associated with high-output industrial applications, including power generation, marine propulsion or auxiliary power, petroleum operations, mining equipment, and other heavy-duty installations.
Because Caterpillar engine configuration varies according to serial-number prefix, arrangement number, rating, application, emissions configuration, and production period, 10R-1284 compatibility should always be verified against the engine serial number, injector number removed from the engine, and applicable Caterpillar parts information before ordering or installation.
