The 101100250 / 86334141 Driving Gear is a core power transmission component for the Montabert HC50 rock drill, serving as the critical interface between the hydraulic motor and the drill’s rotary drive system. This precision-engineered gear transfers rotational torque to the drill bit, enabling efficient rotary cutting while withstanding the extreme vibration and impact loads of hard-rock drilling.
Manufactured to Montabert’s exact factory specifications, this driving gear guarantees a seamless drop-in fit with the HC50’s gearbox and splined shaft assembly, preserving torque transmission efficiency and operational stability. In harsh mining, tunneling, and quarrying environments—where dust, moisture, and heavy loads are constant—it resists wear and fatigue, directly extending the service life and reliability of your Montabert rock drill.
