The Wacker Neuson Gear Pump is a genuine OEM component designed for the RD24-100, RD27-120, and RD28-120 series ride-on articulated tandem rollers. As a direct OEM replacement, this gear pump is sourced to the exact specification used in original production, ensuring a proper installation with no guesswork on fitment. Coverage spans the full RD24 and RD28 family, including standard, combination (C), offset (O), and DPF-equipped variants across multiple build generations. Keep your tandem roller operating at full hydraulic capacity with the correct OEM part.
Key Features
- Genuine OEM Hydraulic Specification — Manufactured to the exact flow rate and pressure ratings required by the RD24/RD28 hydraulic system, ensuring the pump delivers consistent output without cavitation or pressure drop.
- Drop-In Replacement — Matches the original port configuration, shaft dimensions, and mounting pattern for straightforward installation on all covered RD24-100 and RD28-120 tandem roller variants.
- Broad RD-Series Fitment — Compatible with RD24-100, RD27-120, and RD28-120 models including standard, C (combination drum), O (offset drum), and DPF configurations across multiple production generations.
- Sustained Compaction Performance — A properly functioning gear pump maintains hydraulic pressure to the vibratory and propulsion circuits; a worn pump causes sluggish drum response, vibration loss, and reduced compaction output on asphalt and soil.
- Hydraulic System Integrity — Using the correct OEM pump prevents mismatched flow characteristics that can overload downstream hydraulic components, protecting valves, motors, and seals from premature wear.
The gear pump is the heart of the hydraulic circuit on Wacker Neuson RD-series tandem rollers, converting mechanical engine power into pressurized hydraulic flow that drives the drum vibration system and propulsion motors. When the gear pump wears or fails, output pressure drops, causing weak or absent drum vibration, slow travel response, and uneven compaction density across the mat. Replacing a failed pump with a genuine OEM unit like the 5100052898 restores full hydraulic flow and brings the machine back to its designed compaction performance.
