The 86715489 Upper Cylinder is a precision pressure chamber component exclusively engineered as a genuine OEM part for the Montabert HC25 rock drill. As the core of your Montabert rock drill’s impact system, it houses the upper section of the impact piston and guides its high-speed reciprocation (up to 1,600 cycles per minute). This critical component ensures the efficient conversion of hydraulic pressure into impact energy, preserving the factory-calibrated performance of your Montabert rock drill in harsh mining environments.
Manufactured to Montabert’s exact factory specifications, this upper cylinder guarantees a seamless drop-in fit with the HC25’s hydraulic system. It maintains pressure integrity, aligns critical components, and protects internal parts from debris—making it essential for keeping your Montabert rock drill running reliably. As a 100% genuine Montabert part, it is the only choice for restoring factory performance during maintenance or overhaul of your Montabert rock drill.
