Distributor 86746930 for Montabert HC95 Rock Drill

The 86746930 Distributor is the core hydraulic flow control component of the Montabert HC95 rock drill, acting as the "brain" of the percussion system. This precision-machined valve distributor routes high-pressure hydraulic fluid to the cylinder and piston assembly, precisely timing the impact and return strokes to deliver consistent, efficient percussion energy.

Manufactured to Montabert’s exact OEM specifications, this distributor guarantees a seamless drop-in fit with the HC95’s cylinder and valve housing, directly determining the drill’s impact frequency and energy output. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists wear, scoring, and hydraulic fatigue, ensuring reliable performance of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC95 Compatibility
• High-Impact Durability for Mining Operations
