The Wacker Neuson is a genuine OEM Valve Cover Seal designed for the RD18-80, RD18-100, and RD18-100C tandem roller series. As a factory-sourced component, this seal is manufactured to the exact material and dimensional specifications Wacker Neuson requires — ensuring a proper, leak-free fit straight out of the box. The covers an extensive range of RD18 series configurations including US and SE variants, as well as the later.3 revision models. When your roller shows signs of oil seepage around the valve cover, this is the direct replacement seal to reach for.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's specified compression and elastomer grade, so the seal seats correctly against the valve cover surface without over- or under-compression.
- Drop-In Valve Cover Fitment — Profiles match the original groove geometry exactly, so the seal installs the same way the factory part does — no trimming, stretching, or improvising required.
- Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100C configurations across standard, US, SE, and .3 revision variants, making this a single stocking solution for mixed RD18 fleets.
- Prevents Oil Loss at the Valve Cover — A healthy valve cover seal keeps engine oil where it belongs. A cracked or compressed-out seal allows oil to escape, contaminate surrounding components, and signals a pending service issue to operators.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the same part number — 5100029560 — used by authorized Wacker Neuson dealers and service centers.
The valve cover seal forms a compression barrier between the engine's valve cover and the cylinder head, preventing engine oil from escaping around the perimeter of the cover. On a tandem roller like the RD18 series, maintaining this seal is essential to keeping oil consumption in check and avoiding contamination on hot engine surfaces. When the seal ages, hardens, or is disturbed during routine valve cover removal, it loses its ability to compress evenly — leading to visible oil weeping, burning smells, and the potential for oil to reach belts or other drivetrain components if left unaddressed.
