Key Features
- OEM-Matched Drive Geometry — Manufactured to Husqvarna's original dimensional spec, ensuring correct belt wrap angle, groove profile, and rotational balance for the FS400LV drive system.
- Drop-In Replacement — Mounts to the original shaft position using the existing hardware, aligning with the belt path as designed with no improvised adaptation.
- Built for the FS400LV Floor Saw — Confirmed fitment for the FS400LV walk-behind flat saw, a machine used in demanding concrete and asphalt cutting applications.
- Restored Drive Efficiency — A worn or damaged pulley causes belt slippage, uneven blade speed, and excessive wear on surrounding components. Replacing it restores smooth, consistent power transfer to the cutting blade.
A pulley transfers rotational power from the engine to the blade drive belt, maintaining the tension and alignment needed for consistent cutting performance. When a pulley wears, cracks, or becomes misaligned, the drive belt loses proper tracking, leading to slippage, vibration, and accelerated belt wear. Replacing the pulley with a correct OEM component restores proper belt engagement and ensures the FS400LV floor saw delivers steady, controlled power to the blade throughout each cut.
