- Confirmed FS4600G Fitment — Verified for use with the FS4600G floor saw, so you can order with confidence that this is the correct component for your machine.
- Restored Power and Compression — A worn or scored cylinder causes loss of compression, hard starting, and reduced cutting power; replacing it with this OEM unit restores full engine output and smooth operation.
- Genuine Husqvarna OEM Part — Backed by Husqvarna's construction equipment parts program, part number this part meets the same standards as the component installed at the factory.
The cylinder is the core of the engine's combustion chamber, housing the piston and directing the transfer of fuel, air, and exhaust gases that generate power. A cylinder in good condition maintains tight compression, which is essential for reliable starting and consistent power delivery during demanding cutting operations. When a cylinder becomes worn, cracked, or scored — typically from heat stress, inadequate lubrication, or abrasive debris — compression drops, engine performance degrades, and continued operation risks further internal damage.
