Sourced directly from Husqvarna's construction parts catalog, this disc spring delivers an exact fit within the trolley assembly — cross-reference part number 737381401 against your parts diagram to confirm application before ordering. DHS Equipment supplies this part to help keep your cutting trolley operating at full capacity.
Key Features
- Genuine OEM Spring Material — Phosphate-coated to Husqvarna's specification, providing the correct surface treatment for corrosion resistance and consistent spring performance in demanding cutting environments.
- Correct Spring Rate and Geometry — Manufactured to the precise B16 0.6 dimensional profile, ensuring proper load distribution and compression behavior within the trolley mechanism.
- Direct Drop-In Replacement — Engineered to seat and function exactly as the original, with no modification to surrounding components required for installation.
- Broad Cutting Trolley Compatibility — Fits the KV1, KV7, and KV9 cutting trolleys, covering multiple generations of Husqvarna K-series cutter cart configurations.
- Restored Clamping and Tension Function — A worn or fatigued disc spring compromises the trolley's clamping force and guide precision; replacing it with this genuine part restores correct mechanical tension throughout the assembly.
A disc spring is a conical washer-style spring designed to absorb and distribute axial load within a mechanical assembly. In a cutting trolley like the KV1, KV7, and KV9, disc springs maintain consistent clamping pressure and compensate for minor dimensional variation under load, keeping guide components seated firmly during operation. When a disc spring loses its temper, cracks, or deforms, clamping force drops unevenly, which can introduce play into the trolley's tracking and affect cut accuracy.
