The Wacker Neuson Oil Tank is a genuine OEM oil tank designed for the RD18-80, RD18-100, and RD18-100c series double drum rollers, including their.3 generation variants. As a direct OEM part, it is manufactured to the same standards as the original component fitted at the factory, ensuring a correct, hassle-free installation. This part covers fitment across six RD18 configurations, making it the right choice for operators running any model in the RD18-80 through RD18-100c.3 lineup. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this oil tank meets the same material and dimensional specifications as the original, ensuring proper sealing and structural integrity under continuous vibration loads.
- Drop-In Replacement — Matches all original mounting points, port locations, and connection interfaces on the RD18 series, so installation follows the same procedure as the factory-fitted unit.
- Broad RD18 Series Fitment — Compatible with RD18-80, RD18-100, and RD18-100c models as well as their .3 generation updates, covering a wide range of Wacker Neuson tandem roller configurations.
- Sustained Oil Capacity and Containment — A properly functioning oil tank maintains consistent oil supply to the drum drive system; a cracked or leaking tank risks oil starvation, leading to accelerated wear on drive components.
- Leak-Free Integrity — OEM-grade tank material resists cracking and deformation from the heat and vibration typical of compaction work, helping maintain a sealed hydraulic and lubrication circuit over long service intervals.
The oil tank on a Wacker Neuson RD18 series roller serves as the dedicated reservoir that stores and supplies oil to the machine's drum drive or hydraulic circuit, depending on the specific system it feeds. It keeps oil clean, contained, and available at the correct volume to support consistent roller operation. When an oil tank cracks, corrodes, or develops a leak, oil loss can cause drive components to run dry, resulting in overheating, premature wear, and potential mechanical failure — making prompt replacement critical to keeping the roller performing reliably on the compaction site.
