The Wacker Neuson Set Piston Ring is a genuine OEM Set Piston Ring designed for a wide range of Wacker Neuson equipment, including the RD12A-90 tandem rollers, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A. As a factory-sourced component, this set is manufactured to the exact material grade and dimensional tolerances specified for these engines, ensuring a correct seal between the piston and cylinder wall. Whether you are overhauling an RD12A-90 roller or restoring a CRT36-26A trowel, part number delivers the fitment confidence you need to get the job done right.
Key Features
- OEM Ring Geometry and Material Grade — Manufactured to Wacker Neuson's exact ring width, gap clearance, and alloy specification, so compression and oil control behave exactly as the engine was designed to perform.
- Drop-In Piston Compatibility — Rings are sized to install directly onto the OEM piston without filing or shimming, maintaining correct end-gap tolerances straight out of the box.
- Broad Wacker Neuson Fitment — Confirmed for the RD12A-90 roller series, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A generator, covering multiple machine categories under a single part number.
- Restored Compression and Oil Control — Worn or broken rings allow combustion gases to blow past the piston, robbing power and increasing oil consumption. A fresh set restores the compression seal and keeps oil where it belongs.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000226417 carries the same quality assurance as the rings originally installed at the factory.
Piston rings form a dynamic seal between the piston and the cylinder bore, serving two critical functions: containing combustion pressure above the piston to generate power, and scraping excess oil from the cylinder wall to prevent it from burning. When rings wear, lose tension, or break, the engine loses compression, output drops noticeably, and oil consumption rises — symptoms that worsen quickly if left unaddressed. Replacing the full Set Piston Ring at overhaul restores the engine's ability to maintain the cylinder pressures needed for consistent, efficient operation across all the equipment types this part fits.
