The Husqvarna 578373101 Motor Housing is a genuine OEM replacement designed for the WS440, WS440HF, WS442, WS482, and WS482HF wall saws. As a direct factory replacement, this housing is manufactured to the same specifications as the original, ensuring a precise structural fit within the saw's drive assembly. DHS Equipment supplies this part to help keep your wall saw performing at full capacity.
Key Features
- OEM-Matched Structural Integrity — Cast and machined to Husqvarna's original tolerances, this housing maintains the correct alignment and load-bearing capacity required of a wall saw motor enclosure.
- Drop-In Replacement Fit — Engineered to match original mounting points and interface dimensions, this component installs directly into the drive assembly without modification.
- Broad Wall Saw Compatibility — Fits the WS440, WS440HF, WS442, WS482, and WS482HF wall saws, covering both standard and high-frequency variants across the WS series.
- Protects Critical Drive Components — A sound, undamaged motor housing shields the internal motor and gear components from concrete dust, water ingress, and mechanical impact — all common on wall-saw cutting applications.
- Restored Machine Rigidity — A cracked or damaged housing compromises the alignment of the entire drive unit. Replacing it with this genuine OEM part restores the rigid, stable platform the wall saw needs to track accurately on its guide rail.
The motor housing is the structural enclosure that surrounds and supports the wall saw's drive motor, keeping internal components correctly positioned and protected during operation. It bears both the mechanical loads transmitted through the drive system and the environmental stresses of wet, abrasive cutting environments. When the housing is cracked, warped, or broken, motor alignment is lost, vibration increases, and internal components become vulnerable to damage — making prompt replacement essential to maintaining accurate cuts and a serviceable machine.
