The Wacker Neuson Piston Rings Set, 3 Per is a genuine OEM engine component designed for DPU and DPS series vibratory plate compactors as well as the DFS 90 powered floor saw. This set ships with three rings as originally specified, ensuring a complete, like-for-like engine rebuild without the need to source rings individually. As a genuine Wacker Neuson part, is manufactured to the same tolerances as the original rings installed at the factory, helping maintain compression, oil control, and long-term engine integrity. Confirmed fitment includes the DPU 2430F, DPU 2440F, DPU 2450F, DPS 2040, DPS 2050, and DFS 90.
Key Features
- OEM Compression and Oil Control Tolerancing — Each ring is dimensioned to the original bore specification, maintaining the cylinder seal and oil film control that the engine was designed around.
- Complete Three-Ring Set — Includes all three rings per cylinder as originally specified, so a full ring replacement is handled in one part number.
- Direct Engine Rebuild Fit — Drops into the original piston grooves without modification, compatible with the engine configurations found across the DPU and DPS compactor families and the DFS 90 floor saw.
- Broad Model Coverage — Fits the DPU 2430F, DPU 2440F, DPU 2450F, DPS 2040, DPS 2050, and DFS 90, making this a single stocking solution across multiple machines on the same job site.
- Restored Engine Performance — Worn piston rings cause blow-by, oil consumption, and power loss; replacing them with a correctly spec'd set restores compression and returns the engine to full working output.
Piston rings seal the combustion chamber between the piston and the cylinder wall, maintaining compression pressure during the power stroke while also controlling oil consumption by scraping excess oil back down the cylinder bore. A set typically includes a compression ring, a second compression or taper ring, and an oil control ring, each serving a distinct role in keeping the engine running efficiently. When piston rings wear, become stuck in their grooves, or lose tension, the engine will suffer from reduced compression, increased oil burn, excessive smoke, and ultimately a loss of the power output that drives compaction force or blade speed.
