The Wacker Neuson Compensator Tank is a genuine OEM compensator tank designed for the RD24-100 and RD27-120 tandem roller series, including standard, C, and O configurations across multiple generations. As a factory-sourced component, it meets the same material and dimensional standards as the part originally installed at the point of manufacture. Fitment covers a broad range of RD24-100 and RD27-120 variants — from early production models through the current.3-series machines — making this a straightforward like-for-like replacement for roller operators managing a mixed fleet.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this compensator tank is manufactured to the same material grade and dimensional tolerances as the original, ensuring correct hydraulic fluid volume and pressure compensation behavior.
- Direct-Fit Replacement — Mounts to existing ports and brackets without reworking lines or fittings, maintaining the sealed hydraulic circuit integrity the system depends on.
- Broad Tandem Roller Compatibility — Fits the full RD24-100 and RD27-120 model families, including standard, C (combination), and O variants across both the original and .3-series generations.
- Sustained Hydraulic System Performance — A correctly functioning compensator tank keeps hydraulic fluid properly conditioned and pressure-regulated; a degraded or leaking tank leads to erratic drum drive response and accelerated wear on hydraulic components.
- Verified Part Number — Part number 5100012792 cross-references directly to all listed RD-series model numbers, giving you confidence you're ordering the right tank before the machine goes down.
A compensator tank is a sealed reservoir within the hydraulic circuit that accommodates fluid volume changes caused by temperature fluctuation and component movement during operation. It maintains consistent system pressure, preventing cavitation and pressure spikes that would otherwise stress pumps, motors, and valves. When a compensator tank cracks, leaks, or loses its sealing integrity, the hydraulic system can become erratic — leading to inconsistent drum drive, overheating, and potential damage to more expensive downstream components.
