Cummins 3802648 Fuel Injector Assembly

The Cummins 3802648 is a Bosch-type mechanical fuel injector designed for the 6C series 8.3-liter diesel engines. It features a multi-hole nozzle assembly calibrated for precise fuel atomization in high-pressure mechanical injection systems (P7100). The injector body is constructed from high-speed steel to withstand extreme combustion pressures and thermal cycling. This component serves as a direct replacement for Cummins OEM part numbers 3802648, 3926787, and 3926779. Cross-reference interchange includes Interstate McBee M3802648, Bosch 0-432-191-632DX, and J926787. Primary applications encompass Cummins 6CT, 6CTA, 6CTAA, and ISC 8.3 engine variants installed in Case IH 2188, 7250, MX200, MX220, and 8950 agricultural combines, Hyundai R305LC-7 hydraulic excavators, Dongfeng Cummins construction equipment, and marine propulsion units. Installation requires torque specification adherence and nozzle protrusion verification per Cummins service manual.
