The Wacker Neuson Steering Unit and Connection Plate is a genuine OEM assembly designed for the RD18-80, RD18-100, and RD18-100 C series tandem rollers. As a direct factory-sourced component, this part meets the exact design and material standards specified for these machines, ensuring a straightforward installation with no guesswork. It covers an extensive range of RD18 series configurations — including US and SE variants — making it the go-to replacement for operators running any generation of these compact tandem rollers.
Key Features
- OEM Hydraulic Precision — Manufactured to Wacker Neuson's exact tolerances for steering circuit integrity, maintaining correct pressure response and directional control across the full operating range.
- Integrated Assembly — Supplied as a combined steering unit and connection plate, so the hydraulic and mechanical interfaces arrive pre-matched and ready to install as a single unit.
- Broad RD18 Series Coverage — Compatible with RD18-80, RD18-100, and RD18-100 C variants, including US, SE, and .3-generation models, across multiple serial number ranges.
- Restore Full Steering Authority — A worn or failing steering unit causes sluggish, unresponsive, or uneven steering — replacing it with part 5100012656 restores precise articulation and operator control.
- Operator Safety Relevance — Steering system integrity is critical on compaction equipment operating on slopes and near trench edges; using a genuine OEM unit ensures the steering response behaves exactly as the machine was engineered to perform.
The steering unit on a tandem roller controls the articulated joint between the front and rear drum sections, translating operator input into directional movement of the machine. When the steering unit degrades — through seal wear, internal leakage, or connection plate damage — the roller can become difficult to steer accurately, reducing compaction quality and creating a safety concern on uneven ground. Replacing the complete assembly with a genuine OEM unit restores the hydraulic and mechanical connection between the operator controls and the articulation point, putting the machine back in full working order.
