The Wacker Neuson Rings Set.25 is a genuine OEM oversized piston ring set designed for BS50-4, BS50-4s, BS60-4, and BS60-4s series four-stroke vibratory rammers. As a direct Wacker Neuson OEM component, part is manufactured to the same specifications as the rings installed at the factory, ensuring correct cylinder wall contact and compression seal. This.25mm oversize set is intended for engines that have been bored out to accept oversized rings as part of a top-end rebuild. Confirmed fitment spans multiple BS50-4 and BS60-4 variants, including EU-spec models, making it a versatile solution for fleet maintenance across the BS rammer family.
Key Features
- Oversize Compression Seal: — The .25mm oversize dimension is engineered to restore proper ring-to-bore clearance after cylinder boring, re-establishing compression and oil control to original operating levels.
- Genuine OEM Sourcing: — Sourced directly from Wacker Neuson, this ring set is produced to the same material grade and tension spec as the original rings, ensuring consistent seating against a freshly bored cylinder wall.
- Broad BS-Family Coverage: — Fits BS50-4, BS50-4s, BS60-4, and BS60-4s vibratory rammers across standard and EU configurations, covering a wide range of four-stroke rammer build variants.
- Top-End Rebuild Ready: — Correctly sized oversize rings prevent blow-by, restore power stroke efficiency, and stop excessive oil consumption — the common symptoms of a worn or under-spec ring set in a rammer engine.
- Verified Part Number: — Order with confidence using Wacker Neuson part number 5000158641; cross-reference your machine's serial number against the fitment list to confirm the correct oversize specification before installation.
Piston rings form the critical seal between the piston and the cylinder wall inside the engine, controlling compression and preventing combustion gases from escaping into the crankcase. In a vibratory rammer engine that runs under continuous high-cycle load, rings wear over time, leading to lost compression, increased oil consumption, hard starting, and reduced impact force at the shoe. When a cylinder is bored oversize to correct wear or scoring, standard-dimension rings will not seal correctly — an oversized ring set like the 5000158641 .25 is required to restore the proper fit and bring engine performance back to specification.
