The Wacker Neuson 5100011593 is a genuine OEM Steering Unit designed for the RD24, RD27, and RD28 series ride-on tandem rollers. As a direct OEM replacement, this part is sourced from Wacker Neuson and built to the same specifications as the original component installed at the factory, ensuring seamless integration with your machine's hydraulic steering circuit. This unit covers an extensive range of RD24-100, RD27-120, and RD28-120 configurations — including open-drum, combination-drum, DPF, US-spec, and electric-hybrid variants — making it the correct choice across the full tandem roller lineup. Verifying your machine's model number against the fitment list before ordering is always recommended.
Key Features
- Genuine OEM Hydraulic Precision — Sourced directly from Wacker Neuson, this steering unit meets the original hydraulic flow and pressure ratings required for smooth, responsive articulated steering on tandem rollers.
- Drop-In Hydraulic Compatibility — Engineered to match the original port configuration and mounting interface, allowing direct connection to the existing hydraulic lines and frame without reworking fittings.
- Broad RD-Series Fitment — Fits RD24-100, RD27-120, and RD28-120 tandem rollers across open-drum, combination-drum, DPF, US-market, and electric-hybrid model variants.
- Directional Control Restored — A worn or failed steering unit causes sluggish, unpredictable, or unresponsive articulation, directly impacting pass accuracy on asphalt and soil compaction runs. Replacing it restores full operator control.
The steering unit is the hydraulic heart of the articulated steering system on ride-on tandem rollers. It translates operator input — typically from the steering wheel or joystick — into hydraulic pressure that pivots the front and rear frames relative to each other, allowing the machine to follow curves, change direction, and maintain straight tracking during compaction passes. On asphalt and soil applications where tight lane discipline and consistent overlap are critical, a properly functioning steering unit is essential. When this unit begins to fail, symptoms include heavy or stiff steering, drifting, slow hydraulic response, or a complete loss of directional control — any of which can compromise both work quality and operator safety.
