Product Overview
These injectors meter and atomize fuel into the 3204 combustion chambers. Worn nozzles can create hard starting, smoke, rough running and uneven cylinder output.
The 4W7015 injector is widely cross-referenced to 0R3419 and related Caterpillar numbers. A four-piece set matches the four-cylinder 3204 engine configuration, but the engine serial and injector number should still be verified.
