The 86749116 Rear Cover is a critical structural and sealing component at the rear end of the Montabert HC95 rock drill’s hydraulic cylinder assembly. It encloses the internal piston and valve mechanism, maintains high-pressure hydraulic integrity, and provides a rigid mounting interface for the drill’s rear hydraulic connections. This precision-machined cover ensures stable operation under extreme impact and vibration loads, directly influencing the drill’s reliability and service life.
Manufactured to Montabert’s exact OEM specifications, this rear cover guarantees a seamless drop-in fit with the HC95’s cylinder housing, preserving hydraulic pressure integrity and operational stability. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and continuous operation are constant—it resists fatigue, corrosion, and hydraulic leakage, ensuring consistent performance of your Montabert rock drill.
