The Wacker Neuson 5200010186 is a genuine OEM pump to steering hose designed for the RD27-100 and RD27-120 series ride-on tandem rollers. As a factory-original component, it is manufactured to the exact dimensions, pressure ratings, and end fittings specified for these machines, ensuring a direct, trouble-free installation. This hose is confirmed to fit across the full RD27 family, including Basic, Pro, and T4F-tier configurations. When your existing hose shows signs of wear, cracking, or leakage, replacing it with the correct OEM part keeps your steering system performing exactly as designed.
Key Features
- OEM-Matched Hydraulic Integrity — Built to the precise internal diameter, wall thickness, and pressure tolerance required for the RD27 steering circuit, ensuring consistent fluid delivery under working loads.
- Direct-Fit End Connections — Factory-original fittings match the pump outlet and steering valve ports on RD27-100 and RD27-120 machines, so the hose seats correctly without adapter fittings or rework.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 variants, including Basic, Pro, and Tier 4 Final emission-spec rollers in multiple serial number ranges.
- Steering Responsiveness Restored — A compromised pump to steering hose causes sluggish or inconsistent articulation; installing part 5200010186 restores full, predictable steering control on compaction passes.
- Hydraulic Safety Assurance — A failing high-pressure hydraulic hose poses a fluid-injection hazard to operators; using the correct OEM replacement maintains the integrity of the pressurized steering circuit.
The pump to steering hose carries pressurized hydraulic fluid from the hydraulic pump to the steering valve or cylinder, enabling the operator to articulate the roller frame and control the machine's direction of travel. On ride-on tandem rollers like the RD27, precise steering response is critical for accurate pass alignment on asphalt and compacted soil. When this hose deteriorates — through abrasion, heat cycling, or fitting corrosion — it can cause slow steering response, fluid loss, or a complete loss of steering control, all of which halt productive compaction work and create a safety hazard on site.
