The Husqvarna 586916801 Gear Box is a genuine OEM component designed for Husqvarna FS-series floor saws, including the FS4800, FS5000, FS6800, FS7000, FS6600, FS8400, and FS9900. As an OEM part, it is manufactured to the exact specifications of the original assembly, ensuring a correct installation with no guesswork on fit or function. DHS Equipment supplies this part to help keep your floor saws cutting at full capacity.
Key Features
- OEM Gear Geometry and Tolerance — manufactured to Husqvarna's exact gear ratios and housing dimensions, ensuring the drivetrain delivers the same torque transfer as the original unit.
- Drop-In Replacement Assembly — matches the original mounting interface on FS-series floor saws, allowing the gear box to seat and bolt up correctly without modification.
- Broad FS-Series Compatibility — confirmed fitment across seven Husqvarna floor saw models: FS4800, FS5000, FS6600, FS6800, FS7000, FS8400, and FS9900.
- Restored Blade Drive Performance — a worn or failing gear box causes blade speed loss, vibration, and inconsistent cutting depth; replacing it with this unit returns the saw to full cutting performance.
- Structural Durability — built to withstand the continuous high-load demands of production concrete and asphalt sawing, matching the service life expected from the original component.
The gear box is the core power-transfer component in a walk-behind floor saw, taking engine output and converting it into the rotational force that drives the diamond blade. It steps down speed while multiplying torque, allowing the blade to cut through concrete, asphalt, and masonry with consistent, controlled force. When the gear box wears or fails, the result is reduced blade torque, increased vibration, and ultimately an inability to maintain a straight, consistent cut — making timely replacement critical to both productivity and operator control. Cross-reference part number 586916801 against your machine's parts diagram to confirm this is the correct gear box for your specific FS-series model before installation.
