Reliable fuel delivery is the foundation of uptime in heavy-duty diesel operations. The Caterpillar 7C-4184 fuel injector is an original diesel fuel injection assembly engineered for the CAT 3500 Series engine family, with the 3512A as its primary platform. Compatible with CAT 3508, 3508B, 3512, 3512A, 3512B, 3516, and 3516B engines, it serves generator sets, marine propulsion, mining equipment, oilfield power units, and industrial power generation systems.
Designed to meet OEM specifications, the injector delivers accurately metered fuel at precisely controlled timing and pressure. A precision-machined nozzle atomizes diesel into the combustion chamber, supporting optimized combustion efficiency, improved power output, and reduced fuel consumption. High-temperature and corrosion resistance, enhanced durability, and long service intervals make it a dependable component for heavy-duty service. Operators also benefit from lower emissions, better cold-start performance, and stable engine operation in demanding industrial environments.
The 7C-4184 is referenced across OEM, aftermarket, and remanufactured supply chain databases under multiple interchange numbers, including 7C4184, 0R-0906, 4P-9077, 4P-9075, 4P-9076, 7E-6408, 9Y-3773, 0R-2925, 6I-3075, and 10R3053, simplifying global sourcing. To maximize service life, use clean diesel fuel, replace fuel filters regularly, and analyze injector performance periodically. We support CAT dealers, engine rebuilders, marine repair companies, and generator service providers with technical assistance, competitive pricing, and fast worldwide delivery.
