As a direct Husqvarna OEM part, it is manufactured to the exact specifications of the original component, ensuring correct engagement, timing, and load transfer within the drive system.

Key Features
- OEM Sprocket Precision — Manufactured to Husqvarna's exact tooth profile and pitch specifications, ensuring correct chain or belt engagement without slippage or accelerated wear on mating components.
- Direct Assembly Replacement — Supplied as a complete Drive Sprocket Assembly, this component installs directly into the drive system of compatible floor grinders using the original mounting points and hardware.
- Broad PG Series Compatibility — Fits the PG680, PG680RC, PG820, and PG820RC floor grinders, covering both standard and remote-control variants of these professional planetary grinding platforms.
- Restored Drive System Performance — A worn or damaged sprocket causes uneven power transfer to the grinding heads, leading to inconsistent surface finish and increased stress on surrounding drivetrain components. Replacing with this assembly restores smooth, balanced drive output.
- Genuine Husqvarna OEM Quality — Sourced directly from Husqvarna's construction equipment parts program, this assembly meets the same material and dimensional standards as the part originally installed at the factory.
The Drive Sprocket Assembly is a core component of the floor grinder's drive system, transferring rotational power from the motor to the grinding head mechanism. It works in conjunction with the drive chain or belt to maintain consistent torque delivery across the planetary heads, which is critical for achieving an even grind and protecting the machine from drivetrain stress. When the sprocket wears or the assembly becomes damaged, operators will notice irregular head rotation, vibration, or loss of grinding efficiency — all signs that the assembly needs to be replaced to restore proper machine function.
