The Wacker Neuson Steering Unit is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100 C series tandem rollers. Sourced directly from Wacker Neuson, this part meets the same build and performance standards as the unit installed at the factory. It covers a broad range of RD18 series configurations, including US and SE variants, giving you confidence that is the correct part for your machine. Whether you're performing a scheduled rebuild or replacing a failed unit, this steering unit installs directly into compatible RD18 tandem and vibration roller models without adaptation.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the exact flow and pressure tolerances required by the RD18 series steering circuit, ensuring consistent directional response under working load.
- Direct-Fit Replacement — Matches the original port configuration and mounting interface of the factory-installed unit, dropping straight into place on compatible RD18 models.
- Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100 C variants across standard, US, and SE configurations, as well as select vibration roller builds.
- Restored Steering Precision — A worn or failing steering unit causes erratic articulation and loss of directional control; replacing it with a genuine unit restores sharp, predictable steering response on pass.
- Safety-Critical Compliance — Steering is a primary control system on any roller; using a genuine OEM unit ensures the hydraulic response characteristics meet Wacker Neuson's original design intent for safe machine operation.
The steering unit on a tandem roller is the hydraulic control component that translates operator input into precise articulation of the machine's frame. It regulates the flow and direction of hydraulic fluid to the steering cylinder, allowing the roller to follow tight patterns and make accurate passes on a compaction surface. When the steering unit wears or fails, the machine may pull to one side, respond sluggishly, or lose directional control entirely — any of which can compromise both compaction quality and operator safety.
