The Wacker Neuson is a genuine OEM Oversize Piston Rings, 0.25mm set designed for a wide range of Wacker Neuson equipment including VP and WP series single-direction vibratory plate compactors, PT2 centrifugal trash pumps, CT36-6 walk-behind concrete trowels, BFS floor saws, GPi3200 and GPSi3200 portable inverter generators, and RS600 walk-behind rollers. As a genuine Wacker Neuson part, is manufactured to the exact oversize specification required for engines that have been bored to the 0.25mm oversize tolerance, ensuring a proper seal and correct compression restoration after an engine rebuild. This ring set is the correct choice when a standard-size ring will no longer seat properly against a worn or freshly honed cylinder wall. Confirm your engine's bore size and oversize spec before ordering to ensure this is the right ring set for your rebuild.
Key Features
- Exact 0.25mm Oversize Specification — Machined to the 0.25mm oversize tolerance so the rings seat correctly against a bored or honed cylinder, restoring compression to spec after an engine rebuild.
- Genuine Wacker Neuson OEM Quality — Produced to the same metallurgical and dimensional standards as the original rings, ensuring correct ring tension, gap clearance, and oil control for the engine's designed output.
- Broad Cross-Family Fitment — Fits VP and WP single-direction vibratory plate compactors, PT2 trash pumps, CT36-6 concrete trowels, BFS floor saws, GPi3200 and GPSi3200 inverter generators, and RS600 rollers — all sharing a common engine platform.
- Compression and Oil Control Restoration — Worn or broken piston rings allow combustion gases to bypass the piston and oil to enter the combustion chamber; replacing with the correct oversize set restores power, fuel efficiency, and clean exhaust output.
- Rebuild-Ready Drop-In Fit — Designed to install directly into a cylinder bored to the 0.25mm oversize dimension with no additional machining or adaptation to the ring groove required.
Piston rings seal the combustion chamber between the piston and the cylinder wall, controlling compression pressure and preventing engine oil from entering the combustion zone. In a healthy engine, the rings maintain consistent contact with the cylinder bore, allowing the engine to develop full power and run cleanly. When rings wear, lose tension, or break, the result is lost compression, increased oil consumption, blue exhaust smoke, and poor engine performance — all signs that a ring replacement or full engine rebuild is needed. The 5000164788 oversize set is sized for use after the cylinder has been bored out to the 0.25mm oversize dimension, making it an essential component in a proper engine overhaul rather than a like-for-like swap on an unworn bore.
