The Hydraulic Motor 86718004 is original Montabert component, engineered and manufactured exclusively for the Montabert HC25 rock drill. As the official rotational power core of the HC25, this gerotor-type motor is the only choice for maintaining the drill’s factory-spec performance in the most demanding mining and tunneling environments.
Designed to Montabert’s strict engineering standards, it converts high-pressure hydraulic fluid into smooth, consistent rotational force to drive the HC25’s transmission system and drill shank. This ensures the drill delivers its full rated torque and penetration efficiency when breaking hard rock formations like granite and basalt.
As an original Montabert part, the 86718004 hydraulic motor guarantees a seamless, drop-in fit with the HC25’s hydraulic system, requiring no modifications or adjustments. Whether you are performing routine maintenance or a full overhaul, this original component ensures your Montabert rock drill operates at peak reliability, minimizing downtime and protecting your investment in genuine Montabert equipment.
