The SM 1210 is a heavy-duty 24V starter armature precision-engineered for the Kobelco SK210 series excavators. Designed for the high-torque demands of Hino and Mitsubishi engines (such as the J05E), this armature features a 9-tooth (9T) spline. It is built to survive the extreme duty cycles of earthmoving environments, providing consistent breakaway torque for reliable engine ignition.
