The Wacker Neuson Gear Hub Motor is a genuine OEM Gear Hub Motor designed for the RD18-80, RD18-100, and RD18-100C tandem roller series. As a direct OEM replacement sourced through the Wacker Neuson parts network, it meets the same specifications as the original unit installed at the factory. This part covers an extensive range of RD18 configurations including US and SE variants across multiple build generations, giving you confidence that is the right call for your machine. Keep your roller operating at peak compaction performance with a part built to the same standard as the one it replaces.
Key Features
- OEM-Grade Drive Engagement: — Engineered to deliver the correct torque transfer and rotational precision that a Gear Hub Motor requires for consistent drum drive performance.
- Direct-Fit Replacement: — Matches the original mounting interface and port configuration of the RD18 series, allowing a straightforward swap without custom adaptation.
- Broad RD18 Series Coverage: — Fits RD18-80, RD18-100, and RD18-100C tandem rollers across standard, US, SE, and third-generation (.3) build variants.
- Sustained Compaction Output: — A properly functioning Gear Hub Motor keeps drum propulsion smooth and responsive; a worn unit causes loss of drive, uneven compaction, and premature drivetrain stress.
- Genuine Wacker Neuson Part: — Supplied as an authentic OEM component, carrying the part number 5100048104 for straightforward verification against your machine's parts diagram.
The Gear Hub Motor is a core component in the propulsion system of a tandem roller, transmitting hydraulic power into rotational force at the drum hub to drive the machine forward and backward across compaction surfaces. It works in close coordination with the hydraulic circuit to provide controlled, even drum movement — essential for achieving consistent compaction depth and surface quality. When a Gear Hub Motor begins to fail, operators typically notice sluggish or uneven drum response, loss of tractive effort, or hydraulic fluid bypassing internally, all of which compromise both productivity and material compaction results.
