The Husqvarna 504736502 Pulley is a genuine OEM replacement designed for the FS513, FS520, and FS524 floor saws. As a direct factory replacement, this pulley delivers an exact fit within the drivetrain, ensuring proper belt engagement and torque transfer from the moment it is installed. DHS Equipment supplies this part to help keep your equipment running at full capacity on the jobsite.
Key Features
- Genuine OEM Drivetrain Geometry — manufactured to Husqvarna's original dimensional specifications, ensuring correct belt alignment and consistent load transfer across the pulley groove profile.
- Direct Drop-In Replacement — engineered to match the original mounting configuration on the FS513, FS520, and FS524, allowing straightforward installation without modification to surrounding components.
- Broad FS Series Compatibility — a single part number covers the FS513, FS520, and FS524 floor saws, making it the correct choice across this range of professional walk-behind slab saws.
- Restored Belt Drive Performance — a worn or damaged pulley causes belt slippage, uneven wear, and loss of cutting power; replacing it with this genuine component restores consistent blade-speed delivery and smooth operation.
The pulley is a core component of the floor saw's belt drive system, transferring rotational power from the engine or motor to the blade drive belt. It must maintain precise dimensional tolerances to keep the belt tracking true — any wear, cracking, or groove deformation causes the belt to slip or wear unevenly, which directly reduces blade speed and cutting consistency. Replacing a worn pulley with a genuine Husqvarna part, such as part number 504736502, restores the drivetrain to its original operating condition and prevents secondary wear on belts and adjacent drive components.
