The Husqvarna 543042515 Wheel Axle is a genuine OEM replacement component designed for the FS400LV floor saw. As a direct factory replacement, this axle is manufactured to Husqvarna's exact dimensional and material specifications, ensuring a proper fit within the wheel assembly of the FS400LV. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- OEM-Grade Material Integrity — Manufactured to Husqvarna's original dimensional and hardness specifications, ensuring the axle can handle the rotational load and stress demands of a walk-behind floor saw in heavy cutting applications.
- Drop-In Replacement Fit — Engineered to the same tolerances as the original, this axle installs directly into the existing wheel assembly without modification to mounting hardware or surrounding components.
- Built for the FS400LV Floor Saw — Confirmed fitment for the FS400LV, Husqvarna's walk-behind flat saw built for slab and pavement cutting on demanding job sites.
- Restored Wheel Alignment and Tracking — A correctly seated axle keeps the drive wheel centered and true, maintaining straight tracking and consistent cutting depth across the slab.
- Structural Reliability Under Load — Floor saws transmit significant downward and lateral forces through the wheel assembly during cutting; an OEM axle maintains the structural integrity needed to handle those forces without premature wear or deflection.
The wheel axle is the central shaft around which the saw's wheel rotates, supporting the machine's weight and transmitting ground-contact forces during operation and transport. A worn or damaged axle can cause wheel wobble, uneven tracking, and accelerated wear on surrounding bearings and wheel components. Replacing a failed axle with a correct-fit OEM part restores stable, controlled movement and protects the integrity of the broader wheel assembly on your FS400LV floor saw.
