The Husqvarna 502542301 Drive Belt is a genuine OEM replacement designed for PG820 and PG820RC floor grinders. Sourced directly from Husqvarna, this belt matches the original specification for length, width, and material composition — ensuring correct tension and power transfer from the motor to the grinding heads. DHS Equipment supplies this part to help keep your equipment running at full capacity. Cross-reference part number 502542301 against your parts diagram to confirm fitment before ordering.
Key Features
- OEM-Matched Belt Construction — Manufactured to Husqvarna's original tensile strength and elasticity specifications, maintaining consistent load transfer under continuous grinding cycles.
- Drop-In Replacement — Matches the exact profile and length of the original belt, routing onto existing pulleys without adjustment or modification to belt guards or tensioners.
- Confirmed Fitment for PG820 and PG820RC — Verified for both the standard PG820 and the remote-controlled PG820RC planetary floor grinder variants.
- Consistent Power Delivery to Grinding Heads — A correctly tensioned drive belt keeps grinding head speed steady, which directly affects surface finish consistency and disc wear rates.
- Slip and Heat Resistance — Built to handle the thermal and mechanical stress of sustained floor grinding operations, resisting glazing and premature stretching that cause slippage and loss of drive.
The drive belt transfers rotational power from the motor to the planetary grinding head assembly on the PG820 and PG820RC floor grinders. It operates under continuous load and is subject to heat, tension, and friction throughout every grinding pass. When the belt stretches, cracks, or breaks, the grinding heads lose speed or stop entirely, halting production and potentially causing uneven surface results. Replacing a worn belt with the correct OEM part restores full power transmission and ensures the grinder performs to its rated output.
