Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original dimensional and material specifications, ensuring correct belt contact geometry and load-bearing performance for floor saw applications.
- Direct Drivetrain Replacement — Designed to mount directly in place of the original pulley on the FS6800D, with matching bore dimensions and profile for proper belt tracking without modification.
- FS6800D Floor Saw Compatibility — Confirmed fitment for the FS6800D floor saw, a heavy-duty walk-behind slab saw used in demanding concrete and asphalt cutting applications.
- Restored Power Transfer — A correctly seated pulley maintains consistent belt tension and alignment, delivering smooth, efficient power transfer from the engine to the cutting system — a worn or damaged pulley causes belt slip, vibration, and loss of blade speed.
A pulley is a critical component in the floor saw's drivetrain, responsible for routing and tensioning the drive belt that transfers engine power to the blade spindle or propulsion system. When a pulley wears, cracks, or becomes misaligned, it disrupts belt tracking and reduces cutting efficiency — leading to uneven cuts, excessive belt wear, and added stress on surrounding drivetrain components. Replacing a damaged pulley with a genuine OEM unit like this one restores proper power transfer and protects the integrity of the entire drive system.
