The Husqvarna 505417401 Pulley 3VX 4.75 x 8 Gr is a genuine OEM drive pulley designed for the FS6600D, FS6800D, FS6600DT, and FS6600DJDT floor saws. As a direct OEM replacement, this pulley is manufactured to Husqvarna's exact specifications, ensuring the belt drive system operates at the correct alignment, tension geometry, and power transfer ratio. DHS Equipment supplies this part to help keep your floor saw running at full capability.
Key Features
- OEM-Spec Belt Groove Profile — Machined to match the 3VX belt profile exactly, maintaining the correct contact angle and load distribution across the drive system.
- Exact Dimensional Match — The 4.75 x 8 Gr specification aligns with the original pulley geometry, so this component installs directly onto the existing shaft and belt path without modification.
- Broad Floor Saw Fitment — Confirmed for the FS6600D, FS6800D, FS6600DT, and FS6600DJDT floor saws; cross-reference 505417401 against your parts diagram before ordering.
- Restored Drive System Efficiency — A correctly sized pulley keeps belt slip and heat buildup in check, delivering consistent blade speed and cutting power through demanding concrete slab work.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna's OEM supply chain, this pulley meets the same material and dimensional standards as the part it replaces.
A drive pulley transmits engine power to the cutting blade assembly through a V-belt drive system. On floor saws like the FS6600D and FS6800D, the pulley's diameter and groove profile directly control blade speed and the mechanical advantage available during heavy concrete cutting. When a pulley wears, develops groove erosion, or becomes misaligned, the belt begins to slip, generating excess heat that accelerates belt wear and reduces cutting efficiency. Replacing a worn pulley with a correctly spec'd OEM unit restores proper belt tracking and full power delivery to the blade.
