The Husqvarna 541202489 Key 3/8 Square X 4 is a genuine OEM component designed for the PRO65G floor saw. As a factory-sourced replacement, this key is manufactured to Husqvarna's exact dimensional specifications, ensuring a proper mating fit between the shaft and the driven component. DHS Equipment supplies this part to help keep your PRO65G floor saw running with confidence.
Key Features
- OEM Dimensional Accuracy — Manufactured to Husqvarna's exact 3/8-inch square profile, ensuring correct engagement between mating shaft and hub components without slop or misalignment.
- Direct Drop-In Replacement — Engineered to seat precisely in the keyway of the PRO65G, restoring the original drive connection without any reworking of the shaft or hub.
- PRO65G Floor Saw Compatibility — Specifically sourced for the PRO65G floor saw, cross-reference part number 541202489 against your parts diagram to confirm fitment before ordering.
- Torque Transfer Restored — A correctly fitted key locks the shaft and hub together so drive power is transmitted cleanly, preventing slippage that can damage both the shaft and the driven assembly.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna's OEM supply chain, this key meets the same hardness and tolerance standards as the component it replaces.
A shaft key is a small but critical component that locks a rotating shaft to a hub, pulley, or gear, preventing relative rotation between the two parts. When the key is worn, sheared, or missing, the driven component can slip on the shaft, causing lost power transmission and accelerating damage to both the shaft and hub keyways. Replacing a failed key promptly with the correct OEM part restores the original mechanical connection and protects the surrounding drivetrain components from further wear.
