Key Features
- Exact OEM Geometry — Manufactured to Husqvarna's original dimensional specifications, ensuring correct belt seating, proper tension, and consistent drive engagement on the PG680, PG820, PG680RC, and PG820RC floor grinders.
- Drop-In Drive System Fit — This pulley installs directly onto the existing drive shaft mounting, matching the original bolt pattern and bore diameter for a clean, tool-friendly replacement.
- Compatible with PG680, PG820, PG680RC, and PG820RC — Covers both the standard and remote-controlled variants across the PG680 and PG820 floor grinder families.
- Restored Grinding Performance — A worn or damaged pulley causes belt slip, uneven disc speed, and reduced grinding efficiency; replacing it with this genuine OEM part restores consistent rotational output to the grinding heads.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, this component meets the same material and tolerance standards as the part originally fitted at the factory.
The pulley is a core element of the floor grinder's drive system, transferring rotational power from the motor to the belt that drives the grinding head assembly. It must maintain precise alignment and a consistent groove profile to keep belt tension stable and power delivery smooth across the full operating range of the machine. When a pulley wears, cracks, or becomes misaligned, the drive belt begins to slip or wear unevenly, leading to reduced head speed, vibration, and ultimately a loss of grinding consistency — making timely replacement essential to maintaining the machine's output quality.
