The Wacker Neuson 5200009747 is a genuine OEM Exciter Motor designed for the RD7 series walk-behind tandem rollers, including the RD7, RD7A, RD7H, RD7He, and RD7Ye. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. The 5200009747 covers a wide range of RD7 configurations — from standard and hydrostatic variants to yellow-engine and North America-specific models — making it the correct choice across the full RD7 family. When your roller loses vibration output or compaction force drops off, this exciter motor is the direct path back to full performance.
Key Features
- Genuine OEM Vibration Output Spec — Built to the exact eccentric mass and rotational speed rating of the original, ensuring the drum delivers the correct centrifugal force for asphalt and soil compaction.
- Direct Drop-In Installation — Engineered to the same mounting pattern and electrical interface as the factory unit, so the 5200009747 installs in the drum assembly without rework or adaptation.
- Broad RD7 Series Coverage — Fits RD7, RD7A, RD7H, RD7He, and RD7Ye tandem rollers across multiple serial number ranges, including walk-behind and North America-specific configurations.
- Restores Full Compaction Force — A worn or failed exciter motor causes inconsistent or absent drum vibration, leading to under-compacted lifts. Replacing it with this OEM unit brings the machine back to rated amplitude and frequency.
- Verified Wacker Neuson Part Number — Part number 5200009747 is confirmed against the Wacker Neuson parts catalog for the RD7 tandem roller family, eliminating guesswork at the parts counter.
The exciter motor is the component responsible for generating the vibratory force inside each drum of a tandem roller. It works by spinning an eccentric weight at high speed, producing the rapid impacts that compact asphalt or soil beneath the drum. Without a properly functioning exciter motor, the roller operates in static mode only — significantly reducing compaction efficiency and potentially leaving lifts that fail density testing. Over time, bearing wear or motor failure can cause vibration to become erratic or stop entirely, making prompt replacement essential to maintaining productive, on-spec compaction passes.
