Key Features
- Genuine OEM Retention Spec — manufactured to Husqvarna's exact dimensional and tensile specifications, ensuring the Spring Pin seats and retains components with the correct holding force.
- Drop-In Replacement — engineered to match the original mounting interface on PG820RC and PG680RC floor grinders, allowing straightforward installation without reworking adjacent components.
- Confirmed Fitment — compatible with the PG820RC and PG680RC planetary floor grinders, covering both remote-controlled grinding platforms in this series.
- Structural Integrity Restored — a correctly seated Spring Pin locks connected components in position during grinding operation, preventing unwanted movement that can accelerate wear on surrounding parts.
A Spring Pin is a cylindrical fastening component that holds two or more parts in alignment by exerting outward spring tension against the walls of a drilled hole. In a floor grinder like the PG820RC and PG680RC, Spring Pins are used to secure rotating or pivoting assemblies, keeping them positionally fixed under the vibration and load generated during surface grinding. When a Spring Pin becomes worn, compressed, or displaced, the components it retains can shift, leading to misalignment, increased wear on adjacent parts, and inconsistent grinding results.
