The Husqvarna 542190433 Hub Assembly is a genuine OEM replacement built for the FS4800D and FS8400D floor saws. Sourced directly from Husqvarna, this component meets the same design and manufacturing specifications as the original part fitted at the factory. This assembly is a direct replacement for the FS4800D and FS8400D, ensuring correct alignment and secure connection within the wheel and drive system. DHS Equipment supplies this part to help keep your equipment operating at full capability.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact dimensional and material tolerances, ensuring the hub seats and interfaces correctly with mating components in the drive assembly.
- Direct Replacement Fit — engineered to install into the FS4800D and FS8400D without modification, matching original mounting points and load-bearing geometry.
- Compatible with FS4800D and FS8400D Floor Saws — confirmed fitment for both models in the FS heavy-duty walk-behind floor saw lineup; cross-reference part number 542190433 against your parts diagram before ordering.
- Restored Drive Integrity — a correctly functioning hub maintains true wheel alignment and efficient power transfer to the cutting blade, keeping the saw tracking straight and cutting accurately.
- Structural Durability — as an OEM assembly, this hub is built to withstand the continuous load and vibration demands of commercial concrete and asphalt cutting operations.
The hub assembly serves as the central mounting interface between the wheel and the axle or spindle on a walk-behind floor saw. It bears the machine's load, transfers drive force to the wheel, and keeps the wheel running true to its intended path. When a hub assembly wears, cracks, or becomes damaged, the result can be wheel wobble, uneven blade tracking, and accelerated wear on surrounding components — all of which compromise cutting accuracy and operator control on a flat-saw application like the FS4800D and FS8400D.
