The Husqvarna 506397501 Spring is a genuine OEM component designed for K750, K760, K770, and K760II power cutters. As a direct Husqvarna OEM part, it is manufactured to the same specifications as the original, ensuring correct tension, travel, and engagement within the assembly. This spring is confirmed to fit the K750, K760, K760II, and K770 power cutter lineup — cross-reference part number 506397501 against your parts diagram before ordering to verify the correct application. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Tensioning Spec — manufactured to Husqvarna's original load and deflection tolerances, so the spring delivers the correct force for its function within the assembly rather than an approximated aftermarket substitute.
- Drop-In Replacement — matches the original spring's dimensions and hook or coil configuration exactly, installing into the same mounting points without alteration.
- Broad K-Series Compatibility — fits the K750, K760, K760II, and K770 power cutters, covering a wide range of Husqvarna's professional handheld cutting lineup.
- Restored Mechanical Response — a fatigued or broken spring can cause sluggish engagement, rattling, or failure of the mechanism it controls; replacing it restores crisp, consistent mechanical response.
- Verified Husqvarna Part Number — sourced directly under part number 506397501 to eliminate substitution errors and confirm you are installing the correct component for your machine.
A spring transmits and stores mechanical energy within an assembly, maintaining tension or pressure between moving components so they return to a set position after each cycle. In power cutters like the K750, K760, K760II, and K770, springs are used in critical control and engagement mechanisms where consistent force is essential to safe, predictable operation. When a spring weakens through fatigue or breaks entirely, the mechanism it supports may become erratic, fail to engage fully, or allow unwanted movement — making timely replacement important to maintaining normal machine function.
