Part Number 86374055 Accumulator Cover For Montabert HC109 Rock Drill

Precision-Sealed Protection for HC109 Hydraulic Accumulators

Part No. 86374055 is a durable, OEM-spec accumulator cover engineered exclusively for the Montabert HC109 rock drill. Made from high-strength alloy steel, it provides critical sealing of the hydraulic accumulator chamber — maintaining nitrogen/fluid pressure balance, preventing leakage, and shielding internal components from vibration, shock, contamination, and wear.

This component ensures stable energy storage and release, directly supporting consistent impact performance and extended hydraulic system life in harsh underground and surface drilling environments.

Key Advantages

  • Exact OEM fit for Montabert HC109 hydraulic accumulator assembly
  • Forged from high-strength alloy steel for extreme pressure & vibration resistance
  • Precision-machined sealing surfaces prevent hydraulic leakage and gas loss
  • Protects accumulator internals from debris, corrosion, and mechanical impact
  • Validated for continuous operation in mining, tunneling, and heavy civil construction

Applications

  • Montabert HC109 rock drill hydraulic accumulator systems
  • High-pressure energy storage and release in percussive drilling mechanisms
  • Underground mining and hard-rock tunneling operations
  • Heavy-duty construction drilling where reliability and uptime are critical

FAQ

Is this cover compatible with other Montabert models?
No — Part No. 86374055 is dimensionally and functionally validated only for the HC109 rock drill. It is not interchangeable with HC105, HC115, or other series.
Does it include gaskets or mounting hardware?
The cover itself is supplied as a bare metal component. Standard OEM-spec sealing gaskets (Montabert P/N 86374056) and mounting bolts must be ordered separately.
What is the typical lead time for in-stock orders?
In-stock units ship within 1 business day; standard delivery to North America/EU is 3–5 business days via DHL Express.
How does this cover affect accumulator service life?
By preventing contamination ingress and maintaining consistent seal integrity, it extends accumulator service intervals by up to 35% versus non-OEM alternatives.

Detailed Description
