The Husqvarna 580657101 Motor Assembly is a genuine OEM replacement built for the WS440HF and WS440 wall saws. As a factory-sourced component, this assembly is manufactured to the same specifications as the original unit, ensuring the wall saw performs as intended once the repair is complete. DHS Equipment supplies this part to help keep your equipment running through demanding concrete cutting applications.
Key Features
- Genuine OEM Motor Spec — manufactured to Husqvarna's original output and torque specifications for the WS440 wall saw platform, not a generic substitute.
- Direct-Swap Assembly — supplied as a complete motor assembly, simplifying the replacement process and allowing the unit to be swapped directly into the existing mounting configuration.
- WS440HF and WS440 Compatibility — engineered specifically for these wall saw models; cross-reference part number 580657101 against your parts diagram to confirm fitment before ordering.
- Restored Cutting Power — a failed or degraded motor assembly causes loss of blade speed, inconsistent cutting, and potential machine shutdown; this replacement restores full drive performance.
- Electrical Safety Compliance — as an OEM motor assembly, this component meets Husqvarna's original electrical ratings and insulation standards, supporting safe operation of the wall saw.
The motor assembly is the core drive unit of the WS440 series wall saw, converting electrical power into the rotational force needed to spin the diamond blade through reinforced concrete, masonry, and other hard materials. When the motor assembly wears out or fails, the machine loses the drive it needs to maintain consistent blade speed under load, resulting in stalled cuts or complete loss of function. Replacing it with a genuine OEM unit restores the machine to its original operating capability.
