The Husqvarna 542199760 Cylinder is a genuine OEM component designed for the FS8400D floor saw. Sourced directly from Husqvarna's construction equipment line, this cylinder is manufactured to the exact specifications of the original part, ensuring a correct fit and restored engine performance. DHS Equipment supplies this part to help keep your FS8400D floor saw operating at full capacity.
Key Features
- OEM-Grade Bore Tolerancing — Machined to Husqvarna's exact bore dimensions, ensuring proper compression and piston-to-wall clearance for consistent engine output.
- Direct Engine Replacement — Designed to install in place of the original cylinder with no adaptation, using the existing mounting points and porting geometry of the FS8400D engine.
- Confirmed FS8400D Fitment — Engineered specifically for the FS8400D floor saw, so you can cross-reference part number 542199760 against your parts diagram with confidence.
- Restored Engine Compression — A worn or scored cylinder causes loss of compression, hard starting, and reduced cutting power; replacing it with the correct OEM part brings engine performance back to specification.
- Genuine Husqvarna Quality — Produced under Husqvarna Construction standards, using materials suited to the thermal and mechanical demands of a high-cycle floor saw engine.
The cylinder forms the core of the engine's combustion chamber, guiding the piston through each power stroke and containing the pressure generated during combustion. It works alongside the piston rings to maintain compression, and its internal surface finish directly affects how efficiently fuel energy is converted into cutting power. When the cylinder bore becomes worn, scored, or damaged — whether through abrasive dust ingestion, inadequate lubrication, or extended hours — compression drops, the engine runs rough, and the saw loses the sustained power needed to make clean, controlled cuts through concrete or asphalt. Replacing the cylinder with a genuine OEM part restores the engine's mechanical integrity and brings the FS8400D back to its designed performance level.
