The Wacker Neuson 5100024302 Gear Pump is a genuine OEM component designed for the RD24-100 and RD28-120 series tandem rollers. As a direct factory replacement, it meets the exact specifications required by the hydraulic system in these machines, covering standard, open-drum, and combination-drum variants across both series. Verified fitment spans the full RD24-100 and RD28-120 model range, including US-market configurations. Keep your roller operating at full hydraulic capacity with the correct OEM part sourced directly from Wacker Neuson.
Key Features
- Genuine OEM Hydraulic Output Spec — Manufactured to Wacker Neuson's exact flow and pressure requirements for the RD24-100 and RD28-120 hydraulic circuits, ensuring the pump delivers the precise output the system demands.
- Drop-In Hydraulic Replacement — Matches the original mounting interface and port configuration for direct installation into the existing hydraulic circuit without additional fittings or adapters.
- Broad RD Series Coverage — Fits all RD24-100 and RD28-120 variants, including standard, open-drum (O), and combination-drum (C) configurations, as well as US-market models.
- Sustained Drum Drive Performance — A correctly functioning gear pump maintains consistent hydraulic pressure to the drum drive system, enabling smooth, controlled compaction passes on asphalt and soil surfaces.
- Hydraulic System Integrity — A worn or failing gear pump causes pressure loss, erratic drum response, and potential overheating of the hydraulic circuit — replacing it promptly protects downstream components.
A gear pump is the primary source of hydraulic flow in the roller's hydraulic circuit, converting mechanical energy from the engine into pressurized fluid that powers the drum drive, propulsion, and steering functions. In tandem rollers like the RD24-100 and RD28-120, consistent pump output is essential for maintaining even drum speed and compaction force across the full working pass. When a gear pump wears or fails, internal leakage reduces system pressure, leading to sluggish or uneven drum performance, increased heat buildup, and accelerated wear on other hydraulic components.
