Wacker Neuson 5100061677 Set of Piston Rings 0.25

The Wacker Neuson Set of Piston Rings 0.25 is a genuine OEM set of piston rings designed for DS70Y sludge pumps. Sourced directly from Wacker Neuson, this set carries the exact oversized specification — 0.25mm — to match engines that have been bored or honed to that dimension, ensuring correct compression and oil control from the first start. This is the same ring set used in original production, covering the DS70Y 13in and DS70Y 13in LRC model variants. When you need a dependable engine rebuild solution for your DS70 series pump, part number delivers the fit and specification the engine was built around.

Key Features

• Oversized-Specific Ring Geometry — Manufactured to the 0.25mm oversize dimension, so ring-to-bore clearance is correct for engines that have been machined to that spec — no guesswork, no compromise on compression seal.
• Genuine OEM Construction — Produced to Wacker Neuson's original material and tension specifications, delivering the ring land contact and oil scraping performance the engine was engineered around.
• Drop-In Engine Rebuild Fit — Replaces the factory ring set directly; installs into the machined piston grooves the same way as the original, with no modification to pistons or cylinder bores required beyond the standard 0.25mm oversize prep.
• DS70Y Series Coverage — Confirmed fitment for DS70Y 13in and DS70Y 13in LRC sludge pump models, keeping your rebuild on the right part the first time.
• Restored Compression and Power Output — Worn or broken piston rings allow combustion gases to blow past the piston, robbing power and increasing oil consumption. A fresh set of 5100061677 rings restores the tight seal that keeps the engine running at full output.

Piston rings form the dynamic seal between the piston and the cylinder wall, containing combustion pressure and regulating oil consumption inside the engine. There are typically multiple rings per piston — compression rings that hold combustion gases above the piston, and an oil control ring that prevents excess oil from entering the combustion chamber. When rings wear, crack, or lose tension, the engine loses compression, burns oil, produces excess smoke, and delivers reduced power. Replacing a worn ring set — particularly with the correctly sized oversize variant during a rebore — restores the engine's ability to generate full compression and run efficiently.
