The Wacker Neuson is a genuine OEM Steer Unit To Res Hose designed for RD12A-90 and RD12-90 series tandem rollers. As a direct factory replacement, this hose carries hydraulic fluid between the steering unit and the reservoir, maintaining the precise flow and pressure your machine's steering system depends on. It is confirmed to fit multiple RD12-90 and RD12A-90 configurations, including solid ROPS and foldable ROPS variants.
Key Features
- Genuine OEM Construction: — Built to Wacker Neuson's original hydraulic hose specifications, ensuring correct internal diameter, pressure rating, and fitting dimensions for the steering circuit.
- Direct-Fit Replacement: — Engineered to connect directly between the steering unit and hydraulic reservoir using the original routing and end fittings, making installation straightforward.
- Broad RD12 Series Compatibility: — Fits RD12A-90 and RD12-90 tandem rollers across solid ROPS, foldable ROPS, and double-drum configurations.
- Steering Circuit Integrity: — A sound hose keeps hydraulic pressure consistent to the steering unit, giving the operator accurate, responsive directional control during compaction passes.
- Leak Prevention: — Replacing a cracked, swollen, or weeping hose eliminates hydraulic fluid loss that can starve the steering system and lead to unpredictable machine handling on site.
The steer unit to reservoir hose is a hydraulic return line that routes fluid from the steering unit back to the hydraulic reservoir after it has cycled through the steering circuit. On a walk-behind tandem roller like the RD12 series, consistent hydraulic flow through this line is essential for the steering system to respond accurately as the operator guides the machine. When this hose deteriorates — through cracking, swelling, or fitting failure — hydraulic pressure drops, steering response becomes sluggish or erratic, and fluid loss can accelerate wear across the entire hydraulic system.
