The SM 5945 is an industrial-grade, complete Self Starter Motor Assembly specifically engineered for the Hitachi Zaxis 200 series excavators. Operating on a 24V system with a powerful 4.5kW output, this unit is built to provide the high-torque cranking required for Isuzu-sourced engines (such as the 6BG1 and 4HK1). It is designed to endure the extreme vibrations, dust, and moisture of heavy-duty construction and earthmoving environments.
