The Wacker Neuson Set, Ring (Oversize) is a genuine OEM component designed for the PTS4V series pumps. Sourced directly from Wacker Neuson, this oversize ring set meets the exact material and dimensional specifications of the original part, making it the correct choice when rebuilding a worn or out-of-tolerance engine. It is confirmed to fit PTS4V units across multiple serial configurations, so you can order with confidence knowing this is the right part for the job.
Key Features
- OEM-Grade Ring Material — Manufactured to Wacker Neuson's original alloy and surface finish specifications, ensuring proper ring tension and sealing performance after a bore reconditioning job.
- Oversize Dimension for Reconditioned Bores — Sized for use after cylinder boring or honing, dropping directly into a freshly machined bore without additional fitting or machining guesswork.
- PTS4V Series Compatibility — Verified fitment across PTS4V pump configurations, covering multiple production variants within that series.
- Compression and Oil Control Restored — A complete oversize ring set reseals the combustion chamber, recovering lost compression and correcting excessive oil consumption that worn standard-size rings cause.
- Genuine Wacker Neuson Part — Carries the full OEM part number 5100063314, so you can verify the part against your service manual or parts diagram before installation.
Piston rings form the critical seal between the piston and the cylinder wall, controlling compression pressure in the combustion chamber and regulating how much oil reaches the upper engine. Over time, rings wear and the cylinder bore can become oval or tapered, making standard-size rings unable to seat correctly. An oversize ring set is used after the cylinder has been bored or honed to a larger, true dimension — restoring the tight seal needed for full engine power, clean combustion, and proper oil consumption. Neglecting worn rings leads to hard starting, power loss, excessive smoke, and accelerated internal engine wear.
