The Wacker Neuson Gear Hub Motor is a genuine OEM component designed for the RD24-100, RD27-120, RD27-120 C, RD28-120, and RD28-120 C tandem roller series, including Open and US variants. As a direct Wacker Neuson OEM part, the is manufactured to the exact tolerances and output specifications of the original unit it replaces, ensuring correct engagement with the drive train on your roller. This part covers an extensive range of RD-series tandem rollers across multiple production generations, so confirm your machine's serial number against the fitment list before ordering.
Key Features
- OEM-Rated Drive Output — Manufactured to the original torque and rotational speed specifications for the RD-series drum drive system, not a generalized approximation.
- Direct Bolt-In Replacement — Matches the original mounting flange, port configuration, and shaft interface, so it installs into the hub assembly the same way the factory unit does.
- Broad RD-Series Coverage — Fits RD24-100, RD27-120, and RD28-120 tandem rollers across standard, C (combination), O (open), and US variants spanning multiple production generations.
- Consistent Drum Propulsion — A properly functioning gear hub motor delivers smooth, controlled drum drive; a worn or failing unit causes uneven roller travel, loss of traction, and irregular compaction results.
- Genuine Wacker Neuson OEM Quality — Sourced directly through the Wacker Neuson parts network, this component carries the same internal gear tolerancing and seal-grade materials as the original production part.
The gear hub motor is the hydraulic-to-mechanical conversion unit mounted at the drum hub of a tandem roller. It receives pressurized hydraulic flow from the machine's drive circuit and converts that energy into the rotational force that turns the compaction drum. When the gear hub motor wears or fails, the affected drum loses drive power, resulting in the roller pulling to one side, sluggish travel, or complete loss of propulsion on that drum. Keeping this component in good working order is essential for consistent compaction performance and safe, predictable machine handling on the jobsite.
