The 86746492 Cover is a critical structural and hydraulic sealing component for the Montabert HC95 rock drill, serving as the end cap for the drill’s high-pressure hydraulic cylinder and valve assembly. This robust, precision-machined cover encloses the internal piston and valve mechanism, maintains hydraulic pressure integrity, and provides a rigid mounting interface for adjacent components.

Manufactured to Montabert’s exact factory specifications, this cover guarantees a seamless drop-in fit with the HC95’s cylinder housing, preserving operational stability and longevity. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists mechanical stress, hydraulic fatigue, and corrosion, directly extending the service life and reliability of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC95 Compatibility
• High-Impact Durability for Mining Operations
• Hydraulic Sealing & Debris Protection
• Optimized Design for Maintenance Efficiency

The 86746492 Cover is an indispensable replacement part for your Montabert rock drill in all core operational scenarios:

• Sealing the cylinder end of Montabert HC95 rock drills during underground mining blasting hole drilling (up to 40m depth) in hard-rock formations like granite and basalt.
• Maintaining hydraulic pressure integrity in Montabert HC95 rock drills used for tunnel anchor and support hole drilling in wet, dusty infrastructure construction projects.
• Protecting internal components in Montabert HC95 rock drills during quarrying operations for stone cutting, rock excavation, and pre-splitting tasks.
• Restoring factory-spec sealing and structural protection during full overhauls or hydraulic cylinder replacement of Montabert rock drills.
