The Husqvarna 510239001 Pivot Shaft is a genuine OEM replacement designed for the PG400 floor grinder. Sourced directly from Husqvarna, this component matches the original part's dimensions and material grade — ensuring it seats and functions exactly as the factory-installed shaft did. DHS Equipment supplies this part to help keep your PG400 operating at full capacity. Cross-reference part number 510239001 against your parts diagram before ordering to confirm the correct application.
Key Features
- Genuine OEM Construction — machined to Husqvarna's original dimensional tolerances, delivering the material strength and surface finish required for a load-bearing pivot application.
- Direct Drop-In Replacement — engineered to match the original mounting points and shaft geometry of the PG400, so installation follows the standard service procedure without alteration.
- PG400 Floor Grinder Compatibility — verified fitment for the Husqvarna PG400 planetary floor grinder, one of the most widely used machines in concrete surface preparation.
- Restored Pivot Function — a worn or damaged pivot shaft causes play, misalignment, and uneven grinding head movement; replacing it with this shaft brings the machine back to controlled, consistent operation.
- Long-Term Structural Integrity — as a genuine Husqvarna component, this shaft is produced from the same material specification as the original, supporting the stresses of continuous-duty grinding cycles.
The Pivot Shaft is a structural component that forms the rotational connection point within the PG400's grinding head assembly. It allows controlled articulation or rotation between joined parts, keeping the grinding heads tracking correctly across the floor surface. When the shaft wears, develops surface damage, or fails, the assembly develops unwanted movement and inconsistent contact pressure — leading to uneven grinding results and accelerated wear on surrounding components.
