Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional tolerances, this key delivers the precise fit and material hardness required for dependable torque transfer in the FS309 drivetrain.
- Exact Keyway Engagement — Machined to the original profile, this component seats fully into the keyway slot without filing, shimming, or additional fitting work.
- FS309 Floor Saw Compatibility — Confirmed fitment for the FS309 floor saw, so you can cross-reference part number 543081227 against your parts diagram with confidence.
- Restored Power Transfer — A correctly fitted key locks rotating components — such as pulleys, gears, or hubs — firmly to their shaft, ensuring full torque delivery and preventing slippage that can cause component damage.
- Direct OEM Replacement — As a genuine Husqvarna part, the part maintains the same material grade and geometry as the part it replaces, supporting the integrity of the assembly it serves.
A key is a small but critical fastening component that sits in a machined slot — the keyway — between a shaft and a rotating part such as a pulley, sprocket, or gear hub. Its role is to lock those two components together so that rotational force is transferred cleanly from one to the other. When a key shears, deforms, or works loose, the shaft spins independently of the driven component, resulting in a loss of power transmission and potential damage to the surrounding assembly. Replacing a worn or failed key promptly with the correct OEM part restores proper mechanical engagement and protects the components around it.
