The Wacker Neuson Pump is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this is the exact pump specified for these machines, ensuring a direct, verified fit across the full RD27 roller lineup including Pro, Basic, and T4F variants. Whether you're servicing a Ride-On Roller or an RD27 Pro Tandem Roller, part number is the correct OEM replacement to restore your machine to full operating condition. Genuine OEM construction means no guesswork on compatibility — this pump meets the same standards as the original part installed at the factory.
Key Features
- Genuine OEM Hydraulic Integrity — Built to Wacker Neuson's exact flow rate and pressure tolerances for the RD27 hydrostatic drive system, ensuring consistent hydraulic output where it counts.
- Direct-Swap Installation — Matches the original mounting configuration and port layout on RD27-100 and RD27-120 rollers, so the pump seats and connects without modification.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 machines including Pro, Basic, T4F, Tandem, and Ride-On Roller variants.
- Sustained Drive Performance — A healthy pump maintains proper hydraulic pressure to the vibratory and propulsion circuits; a worn or failing pump causes sluggish travel, weak vibration, or complete drive loss.
- OEM Part Number Assurance — Ordering by Wacker Neuson part number 5100027549 confirms you're getting the correct unit — critical when hydraulic component mismatches can cause system damage.
The pump in an RD27 hydrostatic vibratory roller is the heart of the machine's hydraulic system, generating the pressurized flow that powers both the propulsion drive and the vibratory drum circuit. Without adequate pump output, the roller loses the ability to move under load or deliver the compaction force needed for proper asphalt and soil work. When this pump wears out or fails, the symptoms range from slow or uneven travel to a complete loss of drum vibration — either way, compaction quality suffers and the machine is effectively sidelined until the pump is replaced.
