Wacker Neuson 5100066937 Scavenge Valve

The Wacker Neuson Scavenge Valve 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 double drum rollers. As a factory-sourced part, the meets the exact tolerances and material specifications required to maintain proper hydraulic system performance across all covered variants, including standard, cab, offset drum, and DPF-equipped configurations. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components originally installed on your machine, ensuring a direct, accurate replacement every time. Verify your model number against the fitment list below before ordering to confirm compatibility.

Key Features

• Genuine OEM Valve Integrity — Manufactured to Wacker Neuson's original pressure and flow specifications, ensuring the scavenge circuit operates exactly as engineered for these roller models.
• Broad Series Coverage — Fits RD 24-100, RD 27-120, RD 28-120, RD 40-130, and RD 45-140 series machines, spanning standard, cab, offset drum, and DPF variants across multiple build codes.
• Direct Drop-In Replacement — Engineered to match the original port sizing, thread specification, and mounting orientation so the valve seats and seals correctly without modification.
• Protects Hydraulic System Health — A correctly functioning scavenge valve prevents oil starvation and pressure loss in the hydraulic drive circuit; a failed or stuck valve can lead to overheating, cavitation, and accelerated pump wear.
• Sourced from Wacker Neuson's OEM Supply Chain — Supplied as a genuine Wacker Neuson part, not a generic substitute, so you can trust the material grade and dimensional accuracy match what came off the assembly line.

The scavenge valve is a critical component in the hydraulic circuit of a vibratory double drum roller. Its job is to collect low-pressure return or case drain oil and route it back into the main circuit or reservoir, preventing cavitation and ensuring the hydraulic pump and drive motors stay properly supplied with fluid at all times. When the scavenge valve sticks, leaks, or fails to open and close at the correct pressure, the hydraulic system can lose prime, generate excessive heat, and cause accelerated wear or outright failure of the pump and motor — making timely replacement with a correctly specified part essential to keeping the machine productive.
