The Wacker Neuson Ring Second is a genuine OEM component designed for a broad range of Wacker Neuson equipment including MG3 portable generators, ML240 and ML425 light towers, MFS12 and MFS14 floor saws, MFP fire pumps, and ML225 multifunction floodlight towers. As a direct factory-sourced part, the is manufactured to the exact tolerances required by Wacker Neuson, ensuring it seats and seals correctly within the engine assembly. This genuine OEM Ring Second is the correct choice when carrying out scheduled engine maintenance or addressing compression-related performance issues across the supported model range.
Key Features
- OEM Compression Integrity — Manufactured to Wacker Neuson's exact ring profile and material specification, maintaining the compression seal the engine was engineered around.
- Drop-In Engine Fit — Installs directly into the correct ring groove on the piston with no reworking of the bore or piston required.
- Wide Model Coverage — Compatible with MG3 and MG3sd generators, ML240, ML425, and ML225 light towers, MFS12 and MFS14 floor saws, and MFP1.5 and MFP2 fire pumps.
- Restored Engine Performance — A worn or broken second ring allows combustion gases to bypass the piston, leading to power loss, increased oil consumption, and rough running; replacing it restores proper cylinder pressure and output.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the part number 5000406513 for straightforward verification against your service manual or parts diagram.
The second ring on a piston serves a dual purpose: it acts as a secondary compression seal below the top ring, helping to contain combustion pressure within the cylinder, and it assists in controlling oil consumption by scraping excess oil from the cylinder wall on the downstroke. When this ring wears, loses tension, or breaks, the engine typically exhibits reduced power output, increased oil burning, and excessive exhaust smoke. Replacing the Ring Second at the correct service interval — or when these symptoms appear — restores proper engine dynamics and protects the bore from further wear.
