original 6N7828 Fuel Injection Pump Assembly Diesel Engine Parts Replacement for OEM Excavator Bulldozer Wheel Loader Construction Machinery original new injector

Engineered for heavy-duty diesel fuel injection systems, the 6N7828 Injector Plunger Element delivers OEM-equivalent performance across a wide range of industrial engine platforms. Manufactured from hardened alloy steel with precision grinding technology and strict dimensional control, this plunger assembly ensures stable injection pressure, reliable atomization, and consistent fuel metering under demanding operating conditions. Cross-referenced with 6N-7828, 7W5929, 9H5797, 4P9830, 6N7525, 1086633, 1W6541, and 7W6929, it provides seamless drop-in replacement for aftermarket and remanufacturing applications.

The 6N7828 plunger is compatible with 3204, 3204A, 3208, 3208 Turbo, 3304, 3306, 3306B, 3406, 3406B, 3406C, 3408, 3408B, 3408C, 3412, 3412B, and 3412C diesel engines. These engines are widely deployed in excavators, bulldozers, wheel loaders, mining trucks, generator sets, marine propulsion systems, industrial power units, oilfield equipment, and agricultural machinery. Superior wear resistance and tight tolerance machining help reduce fuel consumption, improve engine efficiency, support reliable cold starting, and lower long-term maintenance costs.

For optimal service life, thoroughly clean the injector body before installation, replace worn barrels simultaneously, lubricate the plunger, verify smooth movement, and conduct injection pressure testing followed by calibration. Backed by a 12-month warranty, this brand-new component is an ideal choice for construction, mining, marine, power generation, oil & gas, and agricultural fleet operators worldwide.
