Key Features
- Genuine OEM Construction-Grade Spec — manufactured to Husqvarna's exact dimensional and material tolerances for a retention component, ensuring consistent spring force and secure locking action in the assembly.
- Drop-In Replacement — matches the original mounting profile exactly, seating into the existing bore without modification so the surrounding assembly returns to proper alignment immediately.
- Broad Husqvarna Construction Fitment — compatible across PP-series power packs, WS-series wall saws, and PG-series floor grinders, making this a versatile service part for mixed Husqvarna Construction fleets.
- Restored Mechanical Retention — a worn or missing spring pin allows connected components to shift or disengage under load; replacing it restores the positive locking action the assembly depends on for safe, stable operation.
- Verified OEM Part Number — ordering by part number 577711001 confirms you are receiving the correct Husqvarna-sourced component, not an unverified substitute, eliminating the risk of misfit during reassembly.
A spring pin — also called a roll pin or slotted spring pin — is a hollow, slotted cylindrical fastener that compresses slightly on installation and uses its outward spring tension to hold itself firmly within a drilled bore. In Husqvarna Construction equipment such as power packs, wall saws, and floor grinders, spring pins are used to lock shafts, levers, linkages, and housings in precise rotational or axial positions, preventing unwanted movement under vibration and operational load. When a spring pin shears, deforms, or works loose, the component it retains can shift out of alignment or disengage entirely, leading to loss of function and potential damage to surrounding parts.
