Wacker Neuson 5100066895 Flow Divider

The Wacker Neuson Flow Divider is a genuine OEM component designed for the RD 24-100, RD 27-120, RD 28-120, RD 40-130, and RD 45-140 series tandem vibratory rollers. As a direct factory replacement, this part is sourced from Wacker Neuson to ensure it meets the same specifications as the original unit installed at the time of manufacture. The covers an extensive range of variants across these roller families, including standard, padfoot, offset drum, and DPF-equipped configurations. If your machine is showing signs of uneven hydraulic output or compromised drum drive performance, replacing the flow divider with the correct OEM part is the right first step.

Key Features

• OEM Hydraulic Calibration: — Engineered to the exact flow-splitting ratio required by Wacker Neuson's dual-drum drive system, ensuring neither drum receives a disproportionate share of hydraulic flow.
• Direct-Fit Replacement: — Matches the original port configuration and mounting interface of the 5100066895, dropping into the hydraulic circuit without rework or adaptation of existing lines.
• Broad Series Coverage: — A single part number serves the RD 24-100, RD 27-120, RD 28-120, RD 40-130, and RD 45-140 families, including standard, padfoot (c), offset drum (o), and DPF variants.
• Protects Drum Drive Consistency: — A correctly functioning flow divider keeps both drums turning at equal torque output, preserving compaction uniformity and preventing one-sided drum slip on grade.
• Genuine OEM Sourcing: — Supplied directly from Wacker Neuson, carrying the same part validation as the original component — no substitutions, no guesswork on internal tolerances.

A flow divider is a hydraulic valve that takes a single pressurized supply line and splits it into two equal output streams, regardless of load differences between the two circuits it feeds. On tandem vibratory rollers like the RD series, this function is critical: it ensures both the front and rear drums receive equal hydraulic flow so they rotate at the same speed and deliver consistent compaction force across the full drum width. When a flow divider wears or fails, one drum can receive more flow than the other, causing uneven compaction, drum slip, or loss of propulsion on one end of the machine — problems that are easy to misdiagnose as pump or motor faults until the divider is inspected.
