The 86746898 Cylinder is the core hydraulic pressure chamber of the Montabert HC95 rock drill, housing the strike piston and valve mechanism to convert high-pressure hydraulic energy into linear impact force. This precision-machined cylinder maintains perfect axial alignment of the piston during high-frequency percussion cycles, while preserving hydraulic pressure integrity to deliver maximum impact energy.

Manufactured to Montabert’s exact OEM specifications, this cylinder guarantees a seamless drop-in fit with the HC95’s housing and piston assembly, directly determining the drill’s impact efficiency and service life. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists wear, scoring, and thermal fatigue, ensuring reliable performance 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 86746898 Cylinder is the most critical replacement part for your Montabert rock drill in all core operational scenarios:

• Housing the strike piston in 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 percussion performance during full overhauls or cylinder replacement of Montabert rock drills.
