The Husqvarna 525353401 Spring is a genuine OEM replacement designed for the DM406 concrete core drill. Sourced directly from Husqvarna, this component meets the original engineering specifications for the DM406, making it the correct choice when restoring the machine to full working order. DHS Equipment supplies this part to help keep your equipment running at peak performance.
Key Features
- OEM Spring Specification — Manufactured to Husqvarna's original tension and dimensional tolerances, ensuring correct load and travel behavior within the DM406 drill assembly.
- Direct Drop-In Replacement — Engineered to seat and connect exactly as the original, with no rework or adaptation required to the surrounding components.
- DM406 Compatibility — Confirmed fitment for the DM406 concrete core drill, so you can cross-reference part number 525353401 against your parts diagram with confidence.
- Restored Mechanical Function — A correctly rated spring maintains consistent return force and component positioning; a fatigued or broken spring can cause erratic operation or prevent the drill from functioning as intended.
- Genuine Husqvarna Quality — As an authentic OEM part, this Spring is produced from materials selected to match the service life and performance demands of professional core drilling applications.
A spring in a core drill motor assembly typically provides return force, maintains tension on a mechanism, or holds a component in its correct operating position during the drilling cycle. When a spring weakens, deforms, or breaks, the affected mechanism may fail to reset properly between operations, leading to inconsistent performance or a complete loss of function in that assembly. Replacing a worn spring with the correct OEM part restores the precise load characteristics the DM406 was designed to operate with.
