The Wacker Neuson 5100012710 is a genuine OEM Compensator Tank designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, and RD18-100C configurations. As a direct OEM replacement sourced through the Wacker Neuson parts network, the 5100012710 is manufactured to the same standards as the original component fitted at the factory. This part covers an extensive range of RD18 variants — including US and SE market versions as well as.3-series updates — making it the correct choice for operators running any configuration within the RD18 family. Always cross-reference your machine's model number and serial number before ordering to confirm fitment.
Key Features
- Genuine OEM Construction: — Produced to original Wacker Neuson material and dimensional specifications, ensuring the tank walls, fittings, and capacity match what the hydraulic system was engineered to accept.
- Direct-Fit Replacement: — Designed to drop into the existing mounting position on RD18-series rollers with original hardware, with no fabrication or bracket adaptation needed.
- Broad RD18 Family Coverage: — Confirmed fitment across RD18-80, RD18-100, RD18-100C, and their .3-series successors, as well as US and SE regional variants.
- Hydraulic System Integrity: — A correctly functioning compensator tank maintains stable hydraulic pressure across the roller's drive and vibration circuits; a failed or leaking unit leads to erratic drum behavior and loss of compaction force.
- Tandem Roller-Specific Design: — Engineered specifically for the RD18's walk-behind and ride-on tandem roller architecture, not a universal part adapted to fit.
The compensator tank — sometimes called a hydraulic expansion or surge tank — acts as a pressure buffer within the roller's hydraulic circuit. It absorbs volume changes caused by fluid temperature fluctuations and system pressure spikes, keeping the hydraulic lines properly charged and protecting pumps, motors, and control valves from cavitation and shock loads. When the compensator tank cracks, leaks, or loses its ability to hold charge, the hydraulic system becomes unstable, resulting in uneven drum vibration, sluggish travel response, and potential damage to downstream hydraulic components.
