Product description

Highlights at a glance

  • Core Product Advantage: This motor gear is a direct replacement for the Montabert HC 110 hydraulic rock drill, part number 86666534. Precision-machined to original tooth profile and dimensional specifications, it restores the rotary motor drive transmission within the HC 110 gearbox, enabling reliable torque transfer from the hydraulic motor to the drill rod rotation mechanism during mining and tunnel excavation.
  • Practical Function Design: The motor gear is a helical drive gear in the HC 110 gearbox, transmitting rotational torque from the motor shaft to the gear train driving drill rod rotation. Helical tooth form provides smooth load transfer and reduces impact noise. Accurate tooth pitch, pressure angle, and internal spline bore ensure correct meshing and secure shaft mounting under continuous high-torque drilling loads.
  • Material And Specification Details: Manufactured from alloy steel with case-hardened tooth surfaces for wear resistance and contact fatigue strength under repeated high-torque loading. The gear body resists shock and torsional loads in hydraulic rock drill gearbox operation. Part number 86666534 is produced exclusively for the Montabert HC 110 and is not interchangeable with other models.
  • Application Scenarios: Suitable for gearbox overhaul and motor drive maintenance of the Montabert HC 110 in underground mining, open-pit quarrying, tunnel excavation, and hard rock construction. End users include mine maintenance teams, rock drill repair contractors, quarry operators, and spare parts distributors managing HC 110 drill fleet upkeep.
  • Packaging And Supply Support: Each motor gear is individually packaged to protect tooth surfaces and bore during transport. OEM and bulk supply are available for equipment dealers and maintenance contractors. Part number verification is confirmed before shipment. Sourcing support is available for procurement teams managing Montabert HC 110 gearbox overhaul and spare parts inventory.
