The Wacker Neuson Variable Displacement Pump Drive is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100 C tandem roller series. Sourced directly from Wacker Neuson, this part meets the exact engineering tolerances specified for these machines, ensuring the hydraulic drive system performs as intended. It is a direct-fit replacement for the original unit across the full RD18 family, covering multiple production variants including SE and US-market configurations.

Key Features

  • OEM-Grade Hydraulic Precision — Built to the exact displacement tolerances required for the RD18 drive circuit, ensuring consistent flow and pressure output across the full operating range.
  • Direct-Fit Installation — Matches the original mounting interface and hydraulic port configuration, connecting directly to the existing drive circuit without adaptation.
  • Broad RD18 Series Coverage — Compatible with RD18-80, RD18-100, and RD18-100 C variants, including US, SE, and tandem roller configurations across multiple production series.
  • Sustained Propulsion Performance — A correctly functioning variable displacement pump drive delivers smooth, responsive travel speed and traction control; a worn or failing unit causes erratic drive behavior and loss of compaction pass consistency.
  • Genuine Wacker Neuson Part — Supplied as genuine OEM, giving you full confidence that part number 5100011769 is the correct, authorized replacement for your machine.

The variable displacement pump drive is the heart of the roller's hydraulic propulsion system. It controls the volume of hydraulic fluid delivered to the drive motors, which in turn governs travel speed and directional response of the machine. When this pump begins to wear or fail, operators typically notice sluggish or uneven travel, loss of drive power on grades, or an inability to maintain consistent compaction speed — all of which directly affect output quality and site productivity.
