The Wacker Neuson Gear Motor is a genuine OEM component designed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers. As a direct factory replacement, this gear motor meets the original engineering specifications of the RD11 series, ensuring the drivetrain performs exactly as intended. Sourced directly from Wacker Neuson, the carries the same quality standard as the unit installed at the factory.
Key Features
- Genuine OEM Torque and Flow Matching — Factory-spec hydraulic displacement and torque output ensure the gear motor integrates seamlessly into the RD11's hydrostatic drive circuit without performance compromise.
- Direct Drop-In Replacement — Engineered to the same port configuration and mounting interface as the original, so installation on RD11AEC, RD11V, and RD11A machines follows the standard service procedure.
- RD11 Series Compatibility — Confirmed fitment across all three RD11 variants: the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers.
- Sustained Propulsion and Drum Drive Performance — A correctly functioning gear motor maintains consistent drum rotation and ground-drive response; a worn or failing unit causes loss of propulsion, erratic drum speed, and uneven compaction output.
- Hydraulic Circuit Integrity — Proper internal sealing and precision gear mesh within the OEM unit prevent hydraulic bypass and pressure loss that can cascade into broader drivetrain damage if left unaddressed.
A gear motor converts hydraulic flow from the machine's hydrostatic circuit into rotational mechanical force, driving either propulsion or drum vibration depending on its position in the system. On the RD11 series tandem rollers, this component is central to maintaining controlled, consistent drum movement across the full operating range of the machine. When the gear motor wears or fails, hydraulic fluid bypasses internally, resulting in sluggish or absent drum response, reduced compaction efficiency, and potential overheating of the hydraulic system.
