The Husqvarna 579522401 Lock Washer is a genuine OEM component designed for the DC1400 dust collector. As a direct factory replacement, this lock washer delivers an exact match to the original hardware specification, ensuring a flush, secure seat against the mating fastener without adjustment or modification. DHS Equipment supplies this part to help keep your equipment running with the correct hardware in place.
Key Features
- Genuine OEM Hardware Grade — manufactured to Husqvarna's original material and dimensional specification, with the correct hardness and surface treatment for consistent clamping load retention in a dust collector application.
- Direct Bolt-In Replacement — matches the original fastener stack-up on the DC1400, dropping into position without any reworking of surrounding hardware.
- DC1400 Dust Collector Fitment — confirmed fit for the DC1400 dust collector; cross-reference 579522401 against your parts diagram before ordering to verify the exact position.
- Vibration Resistance — the locking profile resists loosening under the continuous motor vibration and airflow cycling typical of high-volume dust collection, keeping fastened joints secure over extended service intervals.
- Correct OEM Part Number — using part number this part ensures you receive the exact replacement Husqvarna specifies, eliminating the risk of an undersized or overrated washer compromising joint integrity.
A lock washer sits between a fastener and the surface it clamps, using its spring tension or toothed profile to grip both faces and resist rotation under vibration. In a dust collector like the DC1400, where motors and impellers generate constant vibration, a correctly rated lock washer prevents fasteners from backing out over time — a failure that can lead to loose panels, misaligned components, or compromised seals within the dust management system. Replacing a worn or damaged lock washer with the correct OEM specification restores the holding integrity of the fastened joint and supports the reliable operation of the collector as a whole.
