The Husqvarna 502534004 Spacer Plate is a genuine OEM component designed for PG680, PG690, and PG820 floor grinders, as well as their RC remote-control counterparts. As a direct Husqvarna OEM part, this spacer plate is manufactured to the exact tolerances required to maintain proper alignment and clearance within the grinding assembly. This plate is engineered to fit the PG680, PG690, PG820, PG680RC, PG690RC, and PG820RC floor grinders without modification. DHS Equipment provides this genuine replacement to help keep your equipment operating at its best.
Key Features
- Genuine OEM Tolerancing — Manufactured to Husqvarna's exact dimensional specifications, ensuring the correct clearance and spacing within the grinding head assembly.
- Drop-In Replacement Fit — Matches the original mounting geometry of the PG-series grinding assembly, allowing straightforward installation against existing hardware.
- Broad PG-Series Compatibility — Fits PG680, PG690, PG820, PG680RC, PG690RC, and PG820RC planetary floor grinders, covering both standard and remote-control variants.
- Preserves Grinding Head Alignment — Correct spacing between components keeps the planetary grinding system running true, preventing uneven wear on tooling and disc holders.
- Durable Construction — Built from the same material grade as the original part, holding up to the vibration and load cycles inherent to heavy-duty concrete grinding work.
A spacer plate maintains the precise gap and positional relationship between components within the grinding head assembly. On planetary floor grinders like the PG680 and PG690, correct spacing ensures that rotating parts track true, tooling seats properly, and load is distributed evenly across the drive system. When a spacer plate is worn, cracked, or missing, component misalignment can follow — leading to accelerated wear on surrounding parts and inconsistent performance across the grinding surface.
