Key Features

• OEM-Spec Drive Shaft Integrity — Manufactured to Husqvarna's exact dimensional and material tolerances, ensuring the shaft delivers consistent rotational force without flex, vibration, or premature wear.
• Complete 1-Speed Assembly — Supplied as a full 48-inch, single-speed shaft assembly, so all components are matched and ready to install as a unit without sourcing individual sub-parts.
• Designed for the FS9900 Floor Saw — Engineered specifically for the FS9900 large-format floor saw, with geometry and spline profiles matched to the machine's drivetrain layout.
• Restored Cutting Performance — A worn or damaged drive shaft compromises blade speed consistency and cutting depth accuracy; replacing it with this genuine assembly restores the saw's full slab-cutting capability.
• Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, carrying the same quality assurance as the original component fitted at the factory.

The drive shaft assembly is the core power transmission component in a floor saw's blade drive system. It transfers rotational energy from the engine or motor through the drivetrain to the blade spindle, maintaining the blade speed and torque needed to make clean, controlled cuts through concrete and asphalt slabs. A shaft that is worn, bent, or damaged will produce uneven blade rotation, increased vibration, accelerated bearing wear, and loss of cutting precision — all of which can compromise both cut quality and operator control on a large-format machine like the FS9900.
