Brief: In this walkthrough, we highlight key design ideas and how they translate to performance for the 86770195 Retainer Shank, a critical component for Montabert HC95 rock drills. You'll see how this part transmits impact energy, secures alignment, and protects internal components during high-vibration drilling operations in mining and tunneling applications.
Related Product Features:
  • Hardened surface resists indentation and deformation for reliable impact performance in dense rock drilling.
  • CNC-turned and ground to ±0.005mm tolerances on critical surfaces, matching original Montabert factory specifications.
  • Stepped profile design forms a tight seal with the HC95 housing to prevent rock debris and hydraulic fluid leaks.
  • Snap-fit or bolt-on mounting profile enables quick installation in ≤15 minutes without specialized tools.
  • Transmits 18 kJ per-cycle impact energy from the piston to the drill bit for efficient rock fragmentation.
  • Maintains precise centering of the drill bit and piston during operation to prevent premature wear.
  • Acts as a buffer to shield internal components from rock debris and hydraulic fluid contamination.
  • Essential for HC95 rock drills in mining, tunneling, and infrastructure projects drilling up to 30m depth.
FAQs:
  • What is the primary function of the 86770195 Retainer Shank?
    The 86770195 Retainer Shank is a critical load-bearing component that transmits the HC95's 18 kJ impact energy from the piston to the drill bit, maintains precise alignment during drilling, and protects internal components from debris and contamination.
  • How does the manufacturing precision of this retainer shank compare to original parts?
    This retainer shank is CNC-turned and ground to ±0.005mm tolerances on all critical surfaces, including the inner bore, outer diameter, and contact faces, exactly matching Montabert's original factory specifications for optimal performance and compatibility.
  • What are the installation requirements for this component?
    The shank features a snap-fit or bolt-on profile that matches the HC95's housing, requiring no specialized tools. Trained technicians can typically complete installation in 15 minutes or less during routine maintenance procedures.
  • In which applications is the 86770195 Retainer Shank most commonly used?
    This component is essential for Montabert HC95 rock drills performing hard-rock blasting holes in mining operations (up to 30m depth), tunnel anchor/support hole drilling in infrastructure projects, and during maintenance/overhaul procedures to replace worn original parts.
