Gear – Part Number 86746476
The 86746484 Cover is a critical structural and sealing component for the Montabert HC95 rock drill, serving as the front-end protective housing for the drill’s high-pressure hydraulic and shank assembly. As a precision-machined bronze cover, it encloses the valve plate and cylinder head, maintains hydraulic pressure integrity, and blocks abrasive rock dust from entering the drill’s internal impact system.
Manufactured to Montabert’s exact factory specifications, this cover guarantees a seamless drop-in fit with the HC95’s gearbox and cylinder assembly, ensuring operational stability and longevity. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and extreme vibration are constant—it resists corrosion, wear, and thermal fatigue, directly extending the service life and reliability of your Montabert rock drill.
