The Wacker Neuson Piston Complete 0.02 is a genuine OEM component designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series machines. Sourced directly from Wacker Neuson, this piston assembly meets the exact specifications of the original part it replaces. Compatible across both standard and wet-configuration BPS pump models, the is the correct, verified replacement for any rebuild or overhaul of these units.
Key Features
- OEM-Spec Piston Tolerancing — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring correct compression ratios and bore-to-piston clearances within the pump cylinder.
- Drop-In Assembly Replacement — Supplied as a complete piston assembly, making installation straightforward during a cylinder overhaul without the need to source individual sub-components.
- Broad BPS Series Compatibility — Fits BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B models, covering the full range of standard and wet-configuration variants in the lineup.
- Sustained Pump Output — A correctly sized and properly seated piston maintains consistent displacement and pressure output; a worn or incorrectly sized piston causes pressure loss, poor flow rates, and accelerated cylinder wear.
- Genuine Wacker Neuson Part — Supplied as genuine OEM, with part number 5100067161 verified against Wacker Neuson's official parts documentation for total confidence in fitment accuracy.
The piston is the core reciprocating component inside a pump cylinder, responsible for drawing fluid in and displacing it under pressure with each stroke. Its fit within the cylinder bore is critical — even minor dimensional deviation leads to bypassing, reduced output pressure, and excessive heat buildup that shortens the life of surrounding seals and cylinder walls. When a piston wears or develops surface damage, pump performance drops noticeably, and continued operation risks more extensive internal damage requiring a full cylinder replacement rather than a straightforward piston swap.
