The Wacker Neuson 5100004281 Cylinder is a genuine OEM component designed for the DPU80, DPU90, and DPU110 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this cylinder meets the original production specification for the engine assembly used across the full Lec, Lem, and Lekc model variants in these families. Fitment covers a wide range of DPU80, DPU90, and DPU110 configurations, including US-market variants and KMAT units, so confirm your exact model number before ordering. As a genuine OEM part, the 5100004281 is the same cylinder supplied on the production line — no substitution, no compromise.
Key Features
- Genuine OEM Cylinder Bore Integrity — Manufactured to the original bore diameter and surface finish specification, ensuring correct piston-to-wall clearance and proper compression from the first start.
- Direct Engine Assembly Fit — Engineered to mate precisely with the existing crankcase, piston, and head components used across the DPU80, DPU90, and DPU110 engine families — no machining or adaptation needed.
- Broad DPU Series Coverage — Confirmed fitment across DPU80Lec, DPU80Lem, DPU90Lec, DPU90Lem, DPU110Lec, DPU110Lem, and DPU110Lekc variants, including US-market and KMAT configurations.
- Compression Restoration — A worn or scored cylinder causes lost compression, hard starting, and reduced compaction force. Replacing it with part 5100004281 restores full engine output and plate performance on cohesive soil and aggregate applications.
- Emission Compliance Maintained — Correct cylinder geometry is critical to maintaining proper combustion characteristics on EPA/CARB-regulated Lec and Lekc engine variants; using the genuine OEM part keeps the machine within its original emissions profile.
The cylinder is the core structural and functional element of a two-stroke or four-stroke engine's top end — it forms the combustion chamber in which the piston travels to generate power. On Wacker Neuson DPU series reversible plate compactors, the cylinder must maintain precise internal dimensions to sustain compression pressure, support efficient combustion, and transfer power to the exciter mechanism that drives compaction force. When the cylinder bore wears, develops scoring, or is damaged, compression drops sharply — leading to difficulty starting, reduced centrifugal force at the plate, and uneven compaction results. Replacing the cylinder promptly with the correct OEM part returns the compactor to its rated output and prevents further damage to the piston and rings.
