The Wacker Neuson is a genuine OEM Piston designed for a wide range of Wacker Neuson equipment, including CT36 and CT30 walk-behind concrete trowels, WP and VP single-direction vibratory plates, BPU reversible vibratory plates, G-series portable generators, and PT2A trash pumps. As a genuine OEM component, it is manufactured to the same specifications as the original part fitted at the factory, ensuring a direct drop-in replacement with no guesswork on fitment. This piston is the correct service part for an extensive cross-section of Wacker Neuson gasoline-powered equipment sharing a common engine platform. If your CT36, WP1550A, VP2050A, BPU2440A, or any other compatible model is due for an engine rebuild or piston replacement, part number is the verified OEM solution.
Key Features
- OEM-Grade Material and Tolerancing — Manufactured to exact bore diameter and ring-groove specifications, ensuring proper compression seal and thermal expansion control within the cylinder.
- Direct Engine Rebuild Replacement — Designed to install into the shared engine platform used across Wacker Neuson CT trowels, WP/VP vibratory plates, BPU compactors, G-series generators, and PT2A pumps without adaptation.
- Broad Wacker Neuson Compatibility — A single piston part number covering CT36, CT30, WP1540/1550/2050, VP1340/1550/2050, BPU2440/2450/2540, G2.1/G2.5/G5.7, PT2A, and additional models sharing this engine family.
- Restores Full Engine Compression — A worn or scored piston leads to loss of compression, increased oil consumption, hard starting, and reduced power output. Replacing with 5000082004 returns the engine to full operating efficiency.
- Fuel System and Engine Safety Integrity — A correctly sized OEM piston maintains the designed compression ratio, preventing the rich-running and overheating conditions that can result from an ill-fitting aftermarket substitute.
The piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft via the connecting rod. As the air-fuel mixture ignites above it, the piston is driven downward, generating the rotational force that powers the machine. Over time, piston rings wear, the piston skirt can scuff against cylinder walls, and ring grooves widen — all of which allow combustion gases to bypass the piston (blow-by), robbing the engine of power and causing oil burning. Replacing a worn piston with a correctly spec'd OEM unit like the Wacker Neuson 5000082004 restores proper compression, smooth combustion, and full power delivery to the machine.
