The Wacker Neuson Pump is a genuine OEM component designed for RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, this pump is manufactured to the exact specification of the original part, ensuring correct hydraulic output and seamless integration with the roller's drive and vibration systems. Fitment covers multiple machine configurations across the RD27-100 and RD27-120 series, making it the go-to replacement for keeping these rollers running at full capacity. Always verify your machine number against the fitment list before ordering.
Key Features
- Genuine OEM Hydraulic Precision — Built to the exact flow and pressure specifications of the original pump, ensuring consistent hydraulic output across the RD27 roller's propulsion and vibration circuits.
- Direct-Fit Replacement — Engineered to match the original mounting configuration and port layout of the RD27-100 and RD27-120, so installation follows the same procedure as the factory component.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 hydrostatic vibratory rollers in both standard and traction control variants across multiple machine configurations.
- Sustained Compaction Performance — A functioning pump maintains the hydraulic pressure that drives drum vibration and forward/reverse travel; a failing pump results in loss of compaction force or total propulsion failure on the job.
- Verified OEM Part Number — Sourced directly through Wacker Neuson's parts supply chain under part number 5000174322, eliminating guesswork when cross-referencing your service documentation.
The pump in a hydrostatic vibratory roller is responsible for generating and delivering hydraulic flow to the machine's drive motors and vibration system. It converts mechanical energy from the engine into pressurized hydraulic fluid, which powers the drum's rotation and vibratory action as well as the roller's forward and reverse travel. When the pump wears or fails, the machine may exhibit weak or absent vibration, sluggish propulsion, or complete loss of hydraulic function — any of which will halt productive compaction work and require immediate attention.
