The 86754777 Hydraulic Motor 125 is the rotational power heart of the Montabert HC95 rock drill—tasked with converting high-pressure hydraulic fluid (from the drill’s power unit) into the steady, high-torque rotation needed to drive the drill shank through hard rock. In every drilling cycle, this motor delivers the rotational force that pairs with the HC95’s impact piston to break dense materials (e.g., granite, basalt), making it irreplaceable for the drill’s core function.

1. Mounting Compatibility: The motor’s flange (with bolt holes, visible in images) and splined output shaft align 1:1 with the Montabert HC95’s transmission system—no modifications, adapters, or shims are needed for installation.
2. Hydraulic Port Design: Equipped with standard SAE hydraulic ports (protected by blue caps in photos) that form a tight seal with the HC95’s hydraulic lines, eliminating leaks even under 350 bar operating pressure.
3. Ribbed Housing: The motor’s external ribbed design (seen in product photos) increases surface area for passive heat dissipation, preventing overheating during 24/7 continuous drilling.
4. Contamination Resistance: Internal filters (integrated into the port design) trap debris in hydraulic fluid, protecting the gerotor assembly from premature wear.
