Wacker Neuson 5100066917 Flow Divider

The Wacker Neuson Flow Divider is a genuine OEM component designed for the RD24-100, RD28-120, RD40-130, and RD45-140 series tandem rollers. As a direct factory replacement, this part ensures the hydraulic system operates exactly as Wacker Neuson engineered it — maintaining correct flow distribution across the drum drive circuits. It fits a wide range of RD series configurations including standard, c (cab), o (open ROPS), DPF, and.3 variants, making it a versatile stocking part for fleets running multiple roller models. When you order part number, you're getting the exact component specified for your machine — no guesswork, no adaptation.

Key Features

• Genuine OEM Flow Calibration — Manufactured to Wacker Neuson's exact hydraulic flow-splitting tolerances, ensuring equal drum drive pressure distribution without tuning or adjustment.
• Direct Hydraulic Circuit Replacement — Connects directly into the existing hydraulic lines of RD series rollers using OEM port sizing and threading — swaps in like-for-like.
• Broad RD Series Coverage — Fits RD24-100, RD28-120, RD40-130, and RD45-140 families across standard, cab, open ROPS, DPF, and .3 configurations.
• Balanced Drum Drive Performance — A functioning flow divider keeps both drums receiving equal hydraulic flow; a worn or failed unit causes uneven compaction, drum slip, or loss of drive to one roller.
• Genuine Part Number Traceability — Supplied as OEM part 5100066917, backed by Wacker Neuson's parts program for consistent sourcing across service intervals.

A flow divider is a hydraulic component that splits a single pressurized fluid supply into two or more equal output streams, regardless of load differences between circuits. In a tandem roller, this ensures both the front and rear drum drive motors receive the same hydraulic flow, keeping compaction effort consistent and both drums rotating at the correct speed. When a flow divider fails or degrades, one drum can receive more flow than the other, resulting in uneven ground compaction, visible surface tracking, or a complete loss of drive to one drum — all of which compromise both output quality and machine controllability.
