Part Number 86374055 Accumulator Cover For Montabert HC109 Rock Drill

Precision-Engineered Accumulator Cover for Reliable HC109 Hydraulic Performance

Part Number 86374055 is a durable, OEM-compliant accumulator cover engineered exclusively for the Montabert HC109 rock drill. It seals the hydraulic accumulator chamber to maintain nitrogen precharge pressure, prevent fluid leakage, and shield internal components from vibration, shock, contamination, and wear — ensuring consistent impact energy delivery and extended system life.

Manufactured from high-strength alloy steel, this cover meets stringent tolerances for exact fitment and long-term reliability in heavy-duty drilling environments.

Key Advantages

  • OEM-equivalent precision fit for Montabert HC109 hydraulic accumulator assembly
  • High-strength alloy steel construction for extreme pressure, vibration, and impact resistance
  • Critical sealing function: maintains nitrogen precharge pressure and prevents hydraulic fluid leakage
  • Protects accumulator internals from debris, corrosion, and mechanical damage
  • Enables stable energy storage/release — directly supporting consistent piston impact performance
  • Reduces unplanned downtime and extends service intervals in mining & tunneling operations

Applications

  • Montabert HC109 rock drill hydraulic accumulator systems
  • Underground and open-pit mining drilling operations
  • Tunnel boring and civil infrastructure excavation
  • Heavy construction sites requiring high-reliability rock drilling
  • Aftermarket maintenance and emergency replacement programs

FAQ

Is this accumulator cover an OEM part or aftermarket replacement?
This is a certified aftermarket replacement manufactured to OEM specifications — identical dimensions, material grade, and functional performance as the original Montabert 86374055 cover.
Will it fit other Montabert models besides the HC109?
No — Part No. 86374055 is dimensionally and functionally specific to the HC109’s accumulator housing. It is not compatible with HC105, HC115, or other Montabert variants.
What is the typical lead time for bulk orders?
Standard lead time is 3–5 business days for in-stock units; custom or large-volume orders (50+ pcs) ship within 10–12 business days — expedited options available upon request.
Does it include gaskets or mounting hardware?
The cover is supplied as a standalone component. Compatible O-rings and mounting bolts are available separately under recommended part numbers — contact support for your full kit list.

Detailed Description
