The Wacker Neuson Piston is a genuine OEM Piston designed for the BS50-4As, BS60-4As, and BS70-4As series vibratory rammers. Sourced directly through Wacker Neuson's authorized parts program, this is the same piston installed at the factory — ensuring dimensional accuracy and proper fit within the engine assembly. It covers a wide range of BS-4As series configurations including 280 mm and 11-inch shoe variants across both standard and US-market builds.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to Wacker Neuson's exact bore tolerances, ensuring proper compression seal and combustion efficiency within the engine cylinder.
- Direct Drop-In Replacement — Matches the original piston profile and pin bore geometry, allowing straightforward installation without reworking the cylinder or connecting rod.
- Broad BS-4As Series Coverage — Fits BS50-4As, BS60-4As, and BS70-4As vibratory rammers across multiple machine configurations, including 280 mm and 11-inch shoe variants.
- Restores Full Compaction Power — A worn or damaged piston causes loss of compression, rough running, and reduced impact force; replacing it with this genuine part brings the rammer back to full operating output.
- Genuine Wacker Neuson Part — Part number 5100015795 is verified against Wacker Neuson's official parts catalog, giving you confidence you are ordering the correct component for your machine.
The piston is the core reciprocating component inside the engine cylinder, converting combustion pressure into the mechanical force that drives the rammer's impact action. It must maintain a precise fit against the cylinder wall to hold compression — when a piston wears, cracks, or scores, compression drops, the engine loses power, and the machine delivers inconsistent or reduced compaction force. Replacing a failed piston with a correctly specified genuine OEM part restores combustion integrity and returns the rammer to consistent, full-force operation on the compaction site.
