c-aterpillar C7 Series Fuel Injector (Part Number: 10R-7221) Product Details

The c-aterpillar 10R-7221 fuel injector is a premium OEM-grade remanufactured component (also available in new options) specifically engineered for c-aterpillar C7 diesel engines, and it is also compatible with c-at C9 engines. It integrates the advanced Hydraulic Electronic Unit Injection (HEUI) system, featuring precision internal components and high-speed steel construction to deliver consistent, reliable performance that strictly meets c-aterpillar OEM specific-ations. It is widely applicable to C7-powered heavy-duty equipment, including commercial trucks, construction machinery (such as c-aterpillar excavators 324D, 325D), industrial power units, and other heavy equipment, designed to optimize fuel atomization and combustion efficiency—with a flow rate of 120-160 liters per minute—to reduce fuel consumption and minimize exhaust emissions. Manufactured with high-strength heat-resistant alloy and precision-machined internal components, this injector exhibits excellent corrosion resistance, wear resistance, and high-temperature stability, making it well-suited for harsh working environments such as construction sites, mining operations, and long-haul transportation. It effectively addresses common faults caused by aged or damaged injectors, such as unstable idling, power loss, and black smoke emission, and supports direct bolt-on replacement without any engine modific-ations. Each unit undergoes rigorous factory remanufacturing and precision calibration, is equipped with necessary installation gaskets and seals, and backed by a 12-month warranty (up to 24 months for premium options), offering a cost-effective and reliable replacement solution for global c-aterpillar C7 equipment users. Additionally, it is interchangeable with multiple related part numbers, enhancing its versatility in maintenance and replacement scenarios, and a core deposit may apply with full credit available upon return of the old core within 45 days.
