Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact tolerances for the PG530 drive system, ensuring correct pulley diameter, bore dimension, and belt groove profile.
- Direct-Fit Replacement — engineered to install in the original mounting position without modification, maintaining correct belt tension and drive geometry from the first use.
- PG530 Floor Grinder Compatibility — purpose-built for the PG530 planetary floor grinder, matching the OEM assembly it replaces in both form and function.
- Restored Drive Efficiency — a worn or damaged pulley causes belt slippage, uneven grinding head speed, and accelerated belt wear; replacing it with this assembly restores consistent power transfer to the grinding heads.
- Verified Part Number Traceability — cross-reference 579373601 against your machine's parts schematic to confirm the correct assembly variant for your PG530 serial configuration.
The pulley assembly is a core component of the PG530's belt-driven power transmission system, transferring rotational force from the motor to the grinding head drive. It works in conjunction with the drive belt to maintain consistent speed and torque delivery across the grinding heads — essential for achieving an even, controlled finish on concrete and stone surfaces. When the pulley wears, becomes damaged, or loses its profile, belt tracking deteriorates, output speed becomes inconsistent, and surrounding drive components experience increased stress and wear.
