The Wacker Neuson Piston Complete is a genuine OEM component designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series light towers. Sourced directly from Wacker Neuson, this piston assembly meets the exact specifications of the original part installed at the factory — no guesswork, no substitutions. It is confirmed to fit all listed BPS and A5000/160B models, making it the correct choice whether you are servicing a single unit or maintaining a fleet.
Key Features
- OEM-Grade Piston Tolerancing — Manufactured to the precise bore dimensions and material specifications required for correct compression and ring seal performance in Wacker Neuson engines.
- Drop-In Assembly Replacement — Supplied as a complete piston assembly, simplifying installation and ensuring all mating components are matched from the outset.
- Broad BPS and A5000 Series Fitment — Fits BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B light towers, covering the full range of these Wacker Neuson models with a single part number.
- Restores Full Compression Output — A worn or damaged piston causes loss of compression, hard starting, and reduced engine power; replacing with the correct OEM assembly brings engine output back to specification.
- Genuine Wacker Neuson Part — Part number 5100067159 is an authentic Wacker Neuson component, ensuring material grade, coating, and dimensional accuracy match the original equipment.
The piston is the core reciprocating component inside the engine cylinder. It converts the force of combustion into mechanical motion, driving the crankshaft and ultimately powering the machine. A correctly fitted piston maintains the compression seal needed for efficient fuel combustion — when a piston wears, cracks, or loses its ring seal, the engine loses power, burns oil, and can become impossible to start reliably. Replacing a failed piston complete with the correct OEM assembly restores proper compression and gets the engine running as intended.
