A pulley is a core element of the belt-driven power transmission system in a walk-behind floor saw like the FS4600G. It transfers rotational force from the engine to the blade drive, maintaining the correct speed ratio and belt tension needed for steady, controlled cutting. When a pulley wears, cracks, or becomes misaligned, belt slippage and vibration follow — leading to inconsistent blade performance and increased stress on surrounding drive components. Replacing a failed pulley with part number this part restores proper drive function and protects the integrity of the broader drive assembly.
