The Wacker Neuson Flow Divider is a genuine OEM component designed for the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series tandem rollers, including standard, canopy, and open-ROPS configurations. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original, ensuring correct hydraulic circuit behavior across all covered machine variants. This flow divider fits an extensive range of RD-series roller models, including DPF-equipped and Generation 3 (.3) variants, making it a versatile stock item for dealers and service teams running mixed fleets.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured by Wacker Neuson to exact flow-splitting tolerances, ensuring consistent hydraulic output distribution between circuits without drift or imbalance.
- Direct Drop-In Replacement — Matches the original hydraulic port configuration and mounting interface of the 5100012425, allowing straightforward installation with standard tooling.
- Broad RD-Series Compatibility — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, canopy, open-ROPS, DPF, and Generation 3 model variants.
- Balanced Drum Drive Performance — A correctly functioning flow divider maintains equal hydraulic flow to both drums, preserving straight tracking, even compaction force, and consistent surface finish.
- Verified OEM Part Number — Sold under the original Wacker Neuson part number 5100012425, so you can cross-reference against your service manual with confidence before ordering.
A flow divider is a hydraulic component that splits a single pressurized oil supply into two or more equal output streams, regardless of load differences between circuits. On a tandem roller, it ensures both the front and rear drum drive motors receive proportional hydraulic flow, which is essential for maintaining straight travel and uniform compaction across the full drum width. When a flow divider wears or fails, one drum may receive more flow than the other, causing the machine to pull to one side, produce uneven compaction patterns, or behave unpredictably under load.
