The Wacker Neuson 5000406666 is a genuine OEM Cylinder Complete designed for a wide range of Wacker Neuson VP, WP, WPP, WPU, and AP series single-direction vibratory plate compactors. As a factory-original component, this Cylinder Complete is manufactured to the same specifications as the part it replaces, ensuring a direct, trouble-free installation in machines such as the VP1550A, VP1340A, VP2050A, WPU1550A, WPP1550A, AP1550A, and AP1550AW, among others. Sourced directly from Wacker Neuson, you can trust that part number 5000406666 meets the precise tolerances required to keep your compactor running at full capacity. Verify your model number against the fitment list before ordering to confirm compatibility with your specific machine configuration.

Key Features

• Genuine OEM Cylinder Integrity — Manufactured to Wacker Neuson's original bore tolerances and material specifications, ensuring correct compression and piston travel in the engine assembly.
• Drop-In Engine Bay Fit — Engineered to align with existing mounting points, gasket surfaces, and piston components so installation follows the standard engine rebuild procedure without rework.
• Broad Vibratory Plate Compatibility — Fits VP1550A, VP1550AW, VP1340A, VP1340AW, VP2050A, VP2050AW, WP1540A, WP1550A, WP2050A, WPP1550A, WPU1550A, AP1550A, AP1550AW, and additional WP and WPP variants.
• Sustained Compaction Output — A sound cylinder bore maintains correct compression pressure, allowing the engine to deliver the consistent power needed for effective soil, asphalt, and aggregate compaction; a worn cylinder causes power loss, hard starting, and excessive oil consumption.
• Verified OEM Part Number — Ordering by Wacker Neuson part number 5000406666 confirms you are receiving the correct assembly — not a close-fit substitute — reducing the risk of a mismatched rebuild.

The cylinder is the core structural and functional component of a four-stroke engine. It houses the piston and forms the sealed combustion chamber where the air-fuel mixture ignites to generate the power stroke that drives the machine. Over time, the cylinder bore can wear, score, or develop micro-cracks that break the compression seal, leading to lost power, difficult starting, increased fuel consumption, and oil blow-by. Replacing a worn cylinder with a genuine OEM Cylinder Complete restores the engine's compression integrity and returns the vibratory plate compactor to its rated performance.
