Caterpillar original Common Rail Injector Assembly 7E-3381, 7E-3384, 7E-6048 Replacement for OEM 0R-1759 for CAT 3500A 3508 3512 3516 Diesel Engine original new injector

The Caterpillar 7E-3384 fuel injector assembly is a precision-engineered diesel fuel injection component designed for the CAT 3512A engine platform, with compatibility across selected CAT 3500 Series models including 3512, 3508, 3516, 3512B and 3512C (engine serial number verification is required for all non-3512A variants). Manufactured to strict Caterpillar OEM specifications, this cylinder head-mounted injector meets OEM precision standards, with both new and remanufactured units available to accommodate varying operational and budget requirements.

Operating as a high-pressure mechanical fuel metering device, the 7E-3384 injector builds internal pressure to lift its calibrated needle valve, atomizing diesel through precision nozzle orifices to deliver a fine fuel mist for uniform combustion. Constructed from high-strength alloy steel with corrosion-resistant materials and factory flow calibration, it delivers reliable high-pressure injection, industrial-grade durability and long service life, while optimized combustion reduces fuel consumption, lowers exhaust smoke, stabilizes power output and extends overall engine lifespan.

This injector supports a broad range of heavy-duty equipment across core industrial sectors, including diesel generator sets, marine propulsion systems, mining equipment, oil and gas power units and industrial power modules, with worldwide shipping available for global deployments. It cross-references to part number 0R-8479, and customers are advised to verify all cross-reference numbers against engine serial numbers before ordering, as well as follow official CAT installation and maintenance guidelines for sustained optimal performance.
