The Wacker Neuson 5100011795 is a genuine OEM Gear Motor designed for the RD18, RD24, RD27, and RD28 series tandem rollers. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, part 5100011795 meets the exact engineering specifications required for proper drive system operation across this roller family. This part covers an extensive range of configurations including open-drum, combination, DPF-equipped, and canopy variants within the RD18, RD24, RD27, and RD28 lines. Verify your machine's model number and serial number before ordering to confirm the correct application.
Key Features
- Genuine OEM Drive Spec: — Built to Wacker Neuson's hydraulic motor output and torque specifications, ensuring the drum drive system delivers consistent compaction force without speed variation or power loss.
- Direct Hydraulic Circuit Fit: — Engineered to match the port configuration, shaft dimensions, and mounting pattern of the original unit, allowing straight installation into the existing hydraulic circuit.
- Broad RD-Series Coverage: — Compatible with RD18, RD24, RD27, and RD28 tandem rollers across standard, open-drum, combination, DPF, and SE configurations — one part number serving the full mid-size roller lineup.
- Sustained Drum Drive Performance: — A properly functioning gear motor maintains steady, controllable drum rotation under load; a worn or failing unit causes uneven travel speed, drum slippage, or complete loss of propulsion.
- Hydraulic System Integrity: — Correct motor displacement and seal specification prevents internal bypass and heat buildup that can cascade into broader hydraulic system damage if left unaddressed.
The gear motor is a hydraulic-driven rotary actuator that converts pressurized hydraulic flow from the machine's pump into mechanical rotation, which in turn drives the compaction drum or propulsion system. On tandem rollers like the RD18 through RD28 series, the gear motor is central to both forward/reverse travel and drum speed control — two functions that directly determine compaction quality and surface finish. When a gear motor wears internally or develops seal failure, the result is reduced torque output, erratic drum behavior, or a complete inability to propel the machine, making timely replacement essential to keeping the roller productive on asphalt and soil compaction work.
