c-aterpillar Injector N14 Series (Part Number: 3407776) Product Details

The c-aterpillar 3407776 fuel injector is a premium, OEM-compatible heavy-duty diesel injector exclusively engineered for the c-aterpillar N14 series diesel engines, including N14 Celect electronic, non-Celect mechanical, and STC (Sequential Turbocharging) configurations. As a critical core component of the engine’s fuel injection system, it is crafted with high-precision manufacturing techniques to deliver uniform fuel atomization, precise fuel metering, and consistent performance, even in the most demanding operating environments—such as high-temperature industrial plants, dusty construction sites, high-load mining operations, long-haul freight transportation, and rugged agricultural fields. This injector is extensively applied in heavy-duty commercial vehicles, construction machinery, industrial generator sets, mining equipment, and agricultural machinery powered by N14 series engines, serving as a reliable OEM replacement part for equipment maintenance, repair, and performance enhancement. Produced in ISO 9001:2015 and IATF16949 certified facilities—globally recognized quality management systems that ensure rigorous quality control throughout every stage of production—it strictly adheres to c-aterpillar’s original design specific-ations and mandatory product certific-ation standards. It adopts high-strength heat-resistant alloy materials and advanced precision machining technology, boasting exceptional high-temperature resistance, high-pressure stability, and corrosion resistance, which allows it to withstand the harsh conditions of long-term continuous operation and chemical erosion from diesel fuel. The production process incorporates strict quality control measures, from raw material inspection and precision machining to final assembly and 100% pre-delivery performance testing, ensuring consistent quality, reliable operation, and compliance with ISO 9001’s core principles of customer focus and continuous improvement. Its optimized structural design not only improves engine combustion efficiency, reduces fuel consumption and exhaust emissions, but also enhances wear resistance and extends the service life of both the injector and the N14 engine. As a direct bolt-on replacement, it requires no installation modific-ations, is available in standard neutral packaging or customized packaging to meet international export safety standards, and is backed by a 12-month limited warranty, 24/7 efficient after-sales service, free fault diagnosis, and timely global delivery. With flexible order quantities (minimum order quantity of 1 piece), it c-aters to the needs of individual users, bulk purchasers, and maintenance service providers in the transportation, construction, industrial, mining, and agricultural sectors, and is widely recognized as a high-quality matching component for c-aterpillar N14 engine fuel injection systems, with export markets spanning Europe, the United States, Central and South America, Southeast Asia, the Middle East, Africa, and other regions.
