The Wacker Neuson is a genuine OEM V-Belt AV13x644Li designed for the WPU1550A, WPU1550AW, and ZEN-C 20 series plate compactors. As a factory-sourced component, it is manufactured to the exact profile, length, and tension specification required for these machines, ensuring the belt seats correctly in the drive pulley without shimming or adjustment. This genuine Wacker Neuson part covers both the US and standard variants of the WPU1550A and WPU1550AW, as well as the ZEN-C 20 single-direction plates, making it the correct choice across that entire model range.
Key Features
- OEM-Matched Belt Profile — AV13 cross-section and 644Li length are held to the exact dimensions specified by Wacker Neuson, so the belt maintains correct tension and tracking from the first use.
- Drop-In Drive Pulley Fit — Routes directly onto the existing pulleys without re-spacing or re-tensioning the drive system, matching the original routing path on WPU1550A and WPU1550AW compactors.
- Broad Model Coverage — A single part number covers the WPU1550A, WPU1550A-US, WPU1550AW, WPU1550AW-US, and ZEN-C 20, consolidating your replacement belt requirement across the full product family.
- Consistent Power Transfer — A correctly tensioned V-belt delivers smooth, uninterrupted drive from the engine to the exciter mechanism, maintaining full compaction force and plate frequency under load.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so the compound hardness, cord construction, and overall belt geometry match the original fitment specification.
A V-belt is the flexible drive link between the engine output pulley and the exciter unit that generates the compaction vibration in a plate compactor. When the belt is in good condition, engine power is transferred efficiently, keeping plate frequency and impact force at the levels the machine was designed to deliver. As the belt wears, it begins to slip under load — output drops, fuel consumption rises, and eventually the belt can break entirely, bringing the machine to a complete stop mid-job. Replacing a worn belt with the correct OEM part restores the drive system to its original operating efficiency and prevents unplanned stoppages on site.
