The Husqvarna 510238101 Left Arm is a genuine OEM component designed for the PG400 floor grinder. Sourced directly from Husqvarna, this part matches the original assembly specifications, ensuring correct positioning and structural alignment within the grinder's grinding head system. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original design tolerances, delivering the same structural geometry and material grade as the factory-installed component.
- Exact Mounting Compatibility — Engineered to align with the PG400's existing mounting points and hardware, allowing a straightforward, bolt-on installation without modification.
- PG400 Floor Grinder Fitment — Confirmed fit for the PG400 planetary floor grinder, making part selection straightforward — cross-reference 510238101 against your parts diagram to verify.
- Restored Grinding Head Geometry — A correctly fitted left arm maintains proper lateral positioning of the grinding head assembly, preserving consistent surface contact and even floor coverage across passes.
- Structural Integrity Under Load — Floor grinders operate under sustained downward pressure and vibration; this arm is built to withstand those working stresses without deflection or premature wear.
The left arm is a structural component within the PG400's grinding head assembly, responsible for holding and positioning one side of the tooling or satellite disc in correct lateral alignment. When the arm is damaged, bent, or worn, grinding head geometry is thrown off — leading to uneven surface coverage, irregular tooling wear, and reduced finishing quality. Replacing a compromised arm with a genuine OEM part restores the precise geometry the machine relies on for consistent, professional-grade floor grinding results.
