The Husqvarna 590478201 Chassis is a genuine OEM structural component designed for the S26 dust extractor and HTCD20 dust and slurry equipment and floor grinder. As a factory-original part, this chassis is manufactured to Husqvarna's exact specifications, ensuring correct alignment, mounting point integrity, and compatibility with all attached components. DHS Equipment supplies this part to help keep your equipment running with the fit and structural confidence that only a genuine OEM component delivers.
Key Features
- Genuine OEM Construction — manufactured by Husqvarna to original design tolerances, ensuring the structural frame dimensions and mounting interfaces match the equipment exactly as built.
- Correct Structural Fit — all mounting points, attachment interfaces, and housing geometry are engineered to align with the S26 and HTCD20 component assemblies without modification.
- Broad Equipment Compatibility — confirmed fitment for the S26 dust extractor and HTCD20 across both dust and slurry and floor grinder configurations.
- Restored Structural Integrity — a damaged or cracked chassis compromises the alignment of every component it supports; replacing it with this OEM unit restores the machine to its designed operating condition.
- Verified by Part Number — cross-reference 590478201 against your parts diagram to confirm correct application before installation.
The chassis forms the primary structural backbone of the machine, supporting and aligning all major assemblies including the motor, collection system, and external housing. When the chassis is cracked, warped, or damaged, internal components can shift out of alignment, leading to vibration, poor sealing, and accelerated wear on surrounding parts. Replacing the chassis with this genuine Husqvarna part restores the structural foundation the machine depends on for consistent, stable operation.
