The Husqvarna 594182401 Piston is a genuine OEM component designed for the LG504 reversible plate compactor. As a direct Husqvarna OEM part, this piston is manufactured to the exact tolerances and material specifications required for proper engine operation in the LG504. DHS Equipment supplies this part to help keep your compaction equipment running at full capacity.
Key Features
- OEM Dimensional Accuracy — Manufactured to Husqvarna's precise bore tolerances, ensuring correct compression and a proper seal against the cylinder wall.
- Direct Drop-In Replacement — Engineered to match the original piston profile of the LG504, so installation aligns with the existing connecting rod and cylinder without secondary machining.
- LG504 Compactor Fitment — Confirmed fit for the LG504 reversible plate compactor, a heavy-duty machine built for trench backfill and granular soil compaction work.
- Restored Engine Compression — A worn or damaged piston causes loss of compression, hard starting, and reduced compaction force; replacing it with this OEM part restores full power output to the machine.
- Genuine Husqvarna Part — Sourced directly from Husqvarna Construction, part number this part matches the original specification and integrates correctly with all associated engine components.
The piston is a core engine component that moves up and down within the cylinder bore, compressing the air-fuel mixture to drive combustion and transfer power to the crankshaft. In a plate compactor like the LG504, this mechanical power ultimately drives the eccentric weight mechanism that generates compaction force. When a piston wears, develops scoring, or cracks, compression drops off, the engine loses power, and vibration output at the plate suffers — leaving soils and aggregates undercompacted and requiring rework.
