The Husqvarna 505566901 Muffler is a genuine OEM component designed for the FS6800D floor saw. As a direct factory replacement, this muffler is built to match the original mounting configuration, exhaust port dimensions, and thermal tolerances of the FS6800D — ensuring a correct, secure installation without adaptation. DHS Equipment supplies this part to help keep your equipment running at full capacity on the jobsite.
Key Features
- OEM Exhaust Spec Match — Manufactured to Husqvarna's original exhaust backpressure and heat dissipation specifications, preserving the engine performance profile of the FS6800D floor saw.
- Direct Bolt-On Replacement — Engineered to align with the original exhaust port and mounting points on the FS6800D, allowing straightforward installation against the factory parts diagram.
- FS6800D Floor Saw Fitment — Confirmed fit for the Husqvarna FS6800D walk-behind floor saw. Cross-reference part number 505566901 against your parts diagram before ordering.
- Sustained Engine Efficiency — A correctly sealed and functioning muffler maintains proper exhaust scavenging, which directly supports engine power output and fuel efficiency during demanding slab-cutting operations.
- Emissions and Noise Compliance — Replacing a cracked or deteriorated muffler restores the machine's designed exhaust attenuation and emissions control, keeping the saw operating within expected environmental and worksite noise standards.
The muffler channels exhaust gases away from the engine cylinder after combustion, reducing noise and managing the release of hot exhaust safely away from the operator and machine components. On a walk-behind floor saw like the FS6800D, the muffler also plays a role in maintaining the correct exhaust backpressure that supports engine scavenging — meaning a cracked, corroded, or blocked muffler can cause a noticeable drop in power and increased operating temperatures. Replacing a worn muffler with a genuine OEM unit restores the engine's designed exhaust flow and keeps the saw performing to specification.
