The Wacker Neuson is a genuine OEM Hydraulic Hose Assembly 45.50 designed for the RD7 series walk-behind tandem rollers, including RD7H-ES and RD7H-S configurations. Sourced directly from Wacker Neuson, this assembly meets the original engineering specifications for the hydraulic circuit on these double drum vibratory rollers. Verified fitment spans the full RD7 family, covering EU-spec and standard variants, giving you confidence that is the correct part before it ships.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the exact pressure rating and routing geometry specified for the RD7 hydraulic system, ensuring no flow restriction or pressure drop at the connection points.
- Direct Bolt-In Replacement — The 45.50 assembly retains the OEM end fittings and hose length, connecting directly to existing ports without rerouting or adapting hardware.
- Broad RD7 Family Coverage — Confirmed fitment across RD7H-ES, RD7H-S, RD7H, and RD7-RAW variants, including EU-spec machines, walk-behind rollers with no engine, and double drum vibratory roller configurations.
- Sustained Drum Drive Performance — A hydraulic hose in sound condition maintains consistent fluid delivery to the drum drive circuit, keeping compaction output uniform across asphalt and soil surfaces.
- Fuel and Fluid Safety Compliance — OEM hose construction meets the original burst-pressure and temperature ratings for the RD7 hydraulic circuit, reducing the risk of hose failure under operating load.
The hydraulic hose assembly carries pressurized fluid between the pump, control valves, and drive motors that power the drums and propulsion system on the RD7 tandem roller. A correctly functioning hose maintains the steady flow and pressure the hydraulic circuit depends on to deliver consistent drum vibration and forward motion during compaction passes. When a hose cracks, swells, or develops a leak, hydraulic pressure drops, propulsion becomes sluggish or uneven, and fluid loss can damage downstream components — making timely replacement critical to keeping the roller productive and safe on the worksite.
