The Husqvarna 542198858 Pulley is a genuine OEM replacement designed for the FS4800D, FS6600D, and FS6800D floor saws. As a direct OEM component, this pulley is manufactured to the exact geometry and load specifications required by these machines, ensuring the drive system operates as Husqvarna intended. This pulley installs in place of the original without adaptation, making it the straightforward choice when the drive system needs attention on any of these floor saws. DHS Equipment supplies this part to help keep your equipment running.
Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact dimensional and load-bearing specifications, ensuring the drive belt tracks and tensions correctly — critical for consistent blade speed in a floor saw application.
- Direct Drop-In Replacement — Engineered to match the original mounting bore, flange profile, and belt groove of the factory pulley, so installation aligns with existing hardware on the FS4800D, FS6600D, and FS6800D.
- Broad Floor Saw Compatibility — Fits the FS4800D, FS6600D, and FS6800D floor saws, covering a range of Husqvarna's professional walk-behind slab-cutting models.
- Restored Drive System Performance — A worn or damaged pulley causes belt slippage, uneven blade speed, and accelerated belt wear; replacing it with this OEM unit restores proper power transfer from the engine to the blade.
- Verified Part Number — Cross-reference part number 542198858 against your machine's parts diagram to confirm the correct application before installation.
The pulley is a core component of the floor saw's drive system, transferring rotational power from the engine through the drive belt to the blade arbor. It must maintain precise alignment and a consistent groove profile to keep the belt running true under the sustained load of cutting concrete or asphalt. When a pulley becomes worn, cracked, or out of round, belt tension becomes inconsistent, leading to slippage, reduced cutting speed, and premature belt failure — all of which interrupt production on the job. Replacing a faulty pulley promptly with a genuine OEM part like this one restores full drive efficiency and protects the belt and surrounding components from additional wear.
