The Upper Cylinder 86715489 is a precision pressure chamber component exclusively engineered for the Montabert HC25 rock drill. As a core part 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 genuine Montabert 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 original 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.
