Key Features
- Genuine OEM Gear Tolerancing — Manufactured to Husqvarna's exact gear mesh and torque transfer specifications, ensuring the gearbox delivers the same output performance as the original unit it replaces.

- Restored Blade Speed and Cutting Torque — A worn or damaged gearbox causes erratic blade speed, vibration, and loss of cutting torque; replacing it with this unit restores consistent, controlled performance through reinforced concrete and masonry.
- Verified OEM Part Number — Cross-reference part number 581783701 against your machine's parts diagram to confirm the correct application before installation.
The gearbox is the core power-transfer component in a wall saw, converting motor output into the blade rotation speed and torque required to cut through reinforced concrete, block, and masonry. It sits between the drive motor and the blade arbor, and the precision of its internal gearing directly determines how smoothly and consistently the blade spins under load. When a gearbox wears or fails, operators typically notice increased vibration, inconsistent blade speed, unusual noise from the head, or complete loss of blade drive — all of which halt productive cutting and can place additional stress on surrounding components.
For fitment verification, confirm your wall saw model against part number 581783701 using your Husqvarna parts diagram. DHS Equipment supplies this genuine OEM gearbox to help restore full cutting performance to your WS series wall saw.
