The 86241940 Spacer is a precision-machined structural component for the Montabert HC50 hydraulic drifter, designed to maintain critical clearances and alignment between key internal assemblies. This cylindrical spacer ensures proper spacing of the impact mechanism, valve components, and shank assembly, preserving the drifter’s hydraulic efficiency and structural integrity.

Manufactured to Montabert’s exact OEM specifications, this spacer guarantees a seamless drop-in fit with the HC50’s internal assembly, maintaining the precise dimensional tolerances required for optimal performance. In harsh underground mining, tunneling, and quarrying environments—where dust, moisture, and continuous vibration are constant—it resists wear, corrosion, and deformation, ensuring reliable operation of your Montabert rock drill.

• Genuine Montabert Precision for Perfect HC50 Compatibility
• High-Impact Durability for Mining Operations
