The Wacker Neuson Piston is a genuine OEM piston designed for the DPU80Lec, DPU90Lec, DPU110Lec, DPU80Lem, DPU90Lem, and DPU110Lem series vibratory plate compactors. Sourced directly from Wacker Neuson, this is the same part supplied on the original production line — built to the exact tolerances required for proper engine compression and power output. It fits a broad range of DPU plate compactor configurations including EC, EM, and EKC variants, as well as US-market models and the DPU 80/110 KMAT vibration plate. When your compactor needs a piston replacement, is the correct OEM part to restore full performance.
Key Features
- OEM Compression Tolerances Met — Manufactured to Wacker Neuson's exact bore dimensions and ring groove specifications, ensuring proper cylinder sealing and consistent compression for reliable engine output.
- Direct Drop-In Replacement — Engineered to install into the existing cylinder bore without machining or modification, maintaining correct piston-to-wall clearance straight out of the box.
- Broad DPU Series Fitment — Compatible with DPU80, DPU90, and DPU110 plate compactors across Lec, Lem, Lekc, and KMAT configurations, including US-market variants.
- Restores Full Compaction Power — A worn or damaged piston causes loss of compression, hard starting, and reduced centrifugal force output; replacing it with this OEM part brings your plate back to full rated compaction performance.
- Genuine Wacker Neuson Part — Supplied by an authorized source under part number 5100004283, so you know the material grade, weight, and geometry match what the engine was designed around.
The piston is the reciprocating heart of the engine — it travels up and down inside the cylinder bore, compressing the air-fuel mixture and transferring combustion force through the connecting rod to the crankshaft. In a vibratory plate compactor, that crankshaft rotation drives the exciter unit that generates the compaction force, so piston condition directly determines how effectively the machine packs soil, gravel, or asphalt. When a piston wears beyond tolerance or suffers damage — through scoring, cracking, or ring groove wear — compression drops, power falls off, and the engine may fail to start or run cleanly. Replacing it with the correct OEM piston restores the tight seal and mechanical efficiency the engine depends on.
