The Wacker Neuson is a genuine OEM Rear Motor Hose designed for the RD27-120 series tandem rollers, including the RD27 Pro Tandem Roller, RD27 Tandem Roller, and RD27-120 Roller Pro T4F and Basic T4F variants. As a factory-sourced component, the is manufactured to the exact pressure ratings, bore dimensions, and end-fitting specifications required by the hydrostatic drive system on these machines. Drop it in as a direct replacement with confidence — this hose is built to match the original routing, connections, and performance of the part it replaces.
Key Features
- Genuine OEM Hydraulic-Grade Construction — Built to the exact pressure tolerance and internal bore specification of the original hose, ensuring no flow restriction or pressure drop in the hydrostatic drive circuit.
- Direct-Fit End Connections — Engineered with the correct fittings and hose length to match the original rear motor routing on RD27-120 machines, allowing straightforward installation without modification.
- Broad RD27-120 Series Coverage — Compatible across multiple RD27-120 build variants, including the Pro Tandem Roller, Tandem Roller, Ride-On Roller, and both T4F emissions-tier configurations.
- Maintains Hydrostatic Drive Integrity — A fully intact rear motor hose keeps hydraulic fluid flowing at the correct pressure to the rear drum drive motor, supporting consistent drum speed and smooth compaction passes.
- Leak Prevention at a Critical Junction — Hydraulic hose deterioration at the rear motor connection is a common source of fluid loss and drive-system pressure faults; replacing with a genuine hose eliminates that failure point before it sidelines the roller.
The rear motor hose on an RD27-120 tandem roller carries pressurized hydraulic fluid between the machine's hydrostatic transmission and the rear drum drive motor. This flow is what transfers power to the rear drum, enabling forward and reverse travel as well as precise compaction force. When this hose degrades — through cracking, fitting corrosion, or internal delamination — the result can range from minor fluid seepage to a sudden loss of rear drum drive, compromising both machine output and worksite safety. Replacing a worn hose promptly with the correct OEM part keeps the hydraulic circuit sealed and the rear drum performing as intended.
