The Husqvarna 543046647 Washer is a genuine OEM component designed for the PG680, PG820, PG680RC, and PG820RC floor grinders. As a direct Husqvarna OEM part, it is manufactured to the exact specifications required for proper assembly and function within these machines. This washer is the correct fit for all four floor grinder models, ensuring that critical fastened connections maintain the load distribution and clamping integrity Husqvarna engineers intended. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact dimensional and material specifications, ensuring the correct hardness, thickness, and surface finish for reliable load distribution in a floor grinder assembly
- Direct Drop-In Replacement — engineered to match the original mounting configuration on the PG680, PG820, PG680RC, and PG820RC, so the washer seats correctly without modification
- Broad Floor Grinder Compatibility — a single part that crosses across the PG680 and PG820 families, including both standard and remote-control variants
- Protects Fastener Integrity — proper load-spreading across the bearing surface prevents fastener pull-through, surface damage, and connection loosening under the vibration loads typical of planetary floor grinders
- Verified Part Number Fit — cross-reference part number 543046647 against your machine's parts diagram to confirm the correct position before installation
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. In a planetary floor grinder like the PG680 or PG820, where rotating heads generate sustained vibration and mechanical stress, correctly sized and properly hardened washers are essential to keeping bolted connections tight and protecting the surrounding material from damage. When a washer is worn, deformed, or missing, fasteners can work loose or cause surface damage to housings and structural components, leading to misalignment and accelerated wear elsewhere in the assembly.
