The Wacker Neuson is a genuine OEM Exciter Pump designed for the RD7 series walk-behind tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. Sourced directly from Wacker Neuson, this part meets the exact hydraulic specifications required to drive the vibratory exciter system in these compact asphalt and soil rollers. Confirmed fitment spans the full RD7 family, making the correct service replacement for both standard and emission-compliant variants across multiple production runs.
Key Features
- Genuine OEM Hydraulic Specification — Built to the exact flow rate and pressure tolerances specified for the RD7 exciter circuit, ensuring the vibratory drums operate at the correct amplitude and frequency.
- Direct Bolt-In Replacement — Matches the original pump's port configuration and mounting pattern, allowing straightforward installation without custom adapters or line modifications.
- Broad RD7 Family Coverage — Confirmed fit for RD7A, RD7H, RD7He, and RD7Ye tandem rollers across multiple serial number ranges, including North America-only and walk-behind roller configurations.
- Restores Full Compaction Output — A worn or failing exciter pump reduces drum vibration intensity, leading to uneven compaction density and failed mat quality. Replacing with 5100047070 returns the machine to rated compaction performance.
- Hydraulic System Integrity — As a pressurized hydraulic component, using the correct OEM pump prevents seal incompatibility, internal leakage, and downstream damage to the exciter motor and control valves.
The exciter pump is a dedicated hydraulic pump that supplies pressurized fluid to the vibratory exciter mechanism inside each drum of the tandem roller. This hydraulic flow drives an eccentric weight assembly that generates the high-frequency vibration needed to densify asphalt and soil layers during compaction passes. When the exciter pump wears or fails, drum vibration drops off or stops entirely — resulting in insufficient compaction, visible surface defects, and the need to make additional passes that cost time and fuel. Keeping this pump in serviceable condition is essential to maintaining the roller's rated compaction performance on every lift.
