The Wacker Neuson Piston is a genuine OEM Piston designed for a wide range of Wacker Neuson vibratory plates, power screeds, and internal vibrators, including the WP1540A, WP1550A, VP1340, VP1550, VP2050 series, BPU2540A, GV2500A, and PT2A models. As a direct OEM replacement, the is manufactured to the same specifications as the original part, ensuring a correct drop-in fit with no guesswork on compatibility. This piston serves an extensive fitment range spanning both single-direction vibratory plates and multi-application power equipment across the Wacker Neuson lineup. Keep this part number on hand for scheduled rebuilds or unplanned engine repairs to get your equipment back to full output quickly.
Key Features
- OEM Dimensional Accuracy — Manufactured to exact bore diameter and ring-groove tolerances, ensuring proper compression seal and consistent combustion performance across every supported model.
- Direct Drop-In Replacement — Matches the original piston pin bore, crown profile, and skirt geometry for straightforward installation without machining or modification.
- Broad Wacker Neuson Fitment — Compatible with WP1540A, WP1550A, VP1340, VP1550, VP2050 vibratory plates, BPU2540A, GV2500A generators, PT2A pumps, BT24A/BT36A, HP/HPG screed power sections, and more.
- Restored Engine Compression — A fresh piston eliminates blow-by caused by a worn or scored original, restoring full power output and smooth throttle response critical to vibratory compaction performance.
- Genuine Wacker Neuson Part — Supplied directly in the OEM supply chain under part number 5100050566, so you receive the same component that left the factory originally.
The piston is the reciprocating heart of a small engine, converting the force of combustion into the mechanical stroke that drives the crankshaft. It forms a critical seal within the cylinder bore — working alongside the piston rings — to contain combustion pressure and transfer maximum energy to the drivetrain. When a piston wears, cracks, or scores, compression drops, the engine loses power, fuel consumption rises, and in severe cases the engine can seize entirely. Replacing a worn piston with a correct OEM part like the Wacker Neuson 5100050566 restores proper cylinder pressure and keeps the engine running at the output levels your compaction or power equipment demands.
