The Wacker Neuson is a genuine OEM Auxiliary Pump designed for RD16-90 and RD16-100 series tandem vibratory rollers, including hydrostatic variants. As a factory-sourced component, it is manufactured to the exact tolerances and flow specifications required by the original hydraulic circuit — no guesswork, no adaptation. This part fits across multiple RD16-90 and RD16-100 configurations, making it the correct choice whether you're servicing a standard RD16-90 Tandem Roller or a hydrostatic IRH-equipped machine.
Key Features
- OEM-Matched Flow and Pressure Specs — Sourced directly from Wacker Neuson, this Auxiliary Pump meets the exact hydraulic output requirements of the original system, ensuring the circuit operates as engineered.
- Direct-Fit Hydraulic Connection — Engineered to match the original port configuration and mounting interface, allowing straightforward installation into the existing hydraulic system without custom fittings or rework.
- Broad RD16 Series Coverage — Confirmed fitment across RD16-90 and RD16-100 tandem roller variants, including standard and hydrostatic IRH configurations.
- Sustained Auxiliary Circuit Performance — A functioning auxiliary pump maintains pressure to secondary hydraulic functions; a worn or failing pump causes sluggish response, erratic system behavior, or complete loss of auxiliary circuit operation.
- Genuine Wacker Neuson Part — Carrying part number 5000183391, this is an authentic OEM component backed by Wacker Neuson's manufacturing standards — the same part that left the factory floor with your machine.
The auxiliary pump is responsible for supplying hydraulic flow to secondary systems on the roller — functions that operate independently of the main drive circuit. It draws from the hydraulic reservoir and delivers pressurized fluid to support operations such as steering, vibration control, or other ancillary hydraulic demands depending on machine configuration. When the auxiliary pump wears or fails, those secondary functions weaken or stop responding entirely, which can compromise machine control and bring compaction work to a halt.
