The Wacker Neuson Control Block is a genuine OEM component designed for the RD18-100C, RD24-100C, and RD28-120C series tandem rollers, along with the RD27-120C and RD28-120C variants. Sourced directly from Wacker Neuson, this part meets the exact engineering standards of the original component it replaces. It is a direct-fit replacement verified across multiple RD-series configurations, including DPF-equipped models. If you're maintaining or rebuilding a Wacker Neuson tandem roller in this family, the is the correct OEM part for the job.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to Wacker Neuson's original flow and pressure specifications, ensuring the control block regulates hydraulic circuits exactly as engineered for the RD-series platform.
- Direct Bolt-In Replacement — Matches the original port layout and mounting interface of the factory control block, allowing straightforward installation without adapters or modification to existing hydraulic lines.
- Broad RD-Series Compatibility — Fits the RD18-100C, RD24-100C, RD28-120C, RD27-120C, and DPF-equipped variants, covering a wide range of Wacker Neuson tandem roller configurations within a single part number.
- Restored Hydraulic Command and Control — A correctly functioning control block ensures precise operator control over vibration and drive functions; a failed or leaking unit can cause erratic machine response, loss of compaction control, or full hydraulic system shutdown.
- Verified OEM Part Number — Part number 5100052956 is confirmed against Wacker Neuson's official parts documentation, so you can order with confidence that this is the right part for your machine.
The control block is a central hydraulic valve assembly that directs and regulates pressurized fluid flow to multiple circuits within the machine — typically managing functions such as drive, vibration, and steering response on a tandem roller. It acts as the command hub between the operator's inputs and the hydraulic actuators that move and compact the drum. When a control block begins to fail, symptoms can include sluggish or unresponsive machine movement, inconsistent vibration output, internal hydraulic leaks, or a complete loss of one or more machine functions — all of which directly compromise compaction performance and operator safety on the job.
