The SM 5949 is a heavy-duty, industrial-grade Self Starter Motor Assembly specifically engineered for Kobelco SK140 series excavators. Operating on a 24V system with a robust 5.0kW output, this unit is built to provide the high-torque cranking required for Isuzu or Mitsubishi-sourced engines typically found in the 14-ton class. It is designed to endure the high-vibration and dusty conditions of construction and earthmoving sites.
