Description

In HC20 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Front cover 86676863 is the “front-line protective barrier”—it’s installed at the drill’s front end to shield core components (like the piston and shank) from mining debris, while sealing hydraulic interfaces to avoid oil waste.

From mining maintenance experience, generic front covers often fail early: low-strength materials (tensile strength < 500 MPa) crack under rock impact in 1800-2000 hours, and imprecise seal grooves cause oil leaks (wasting 2-4 liters monthly).
This Front cover 86676863, as genuine OEM, meets Montabert’s strict standards:
  1. Durability: Heat-treated alloy steel (tensile strength ≥ 650 MPa) resists cracks for long-term use.
  2. Sealing precision: Seal grooves are machined to ±0.002mm tolerance, ensuring tight fit with seals—no leaks.
  3. Debris resistance: Reinforced edge design blocks large rock chips, protecting internal parts.
With short delivery (no 2-3 week waits like generics) and competitive pricing, it’s ideal for mines prioritizing reliability—keeping HC20’s internal components safe for years.
