The Wacker Neuson Exciter Housing Motor Cover is a genuine OEM component designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES, RD7H-S, and RD7 double drum vibratory roller variants. As a direct factory replacement, this cover is manufactured to the same specifications as the original part, ensuring a proper fit over the exciter housing motor assembly. Whether you are servicing an RD 7ES, RD 7S, or a base RD7H double drum roller, part number is the correct OEM choice to restore your machine to operating condition.
Key Features
- Genuine OEM Construction: — Molded and finished to the same dimensional tolerances as the original cover, ensuring correct sealing and alignment over the exciter housing motor.
- Direct-Fit Replacement: — Mounts to the existing exciter housing mounting points with no rework needed, matching the original bolt pattern and profile of the RD7 platform.
- Broad RD7 Series Coverage: — Compatible with RD7H-ES, RD7H-S, RD 7ES, RD 7S, and RD7 double drum vibratory roller configurations, including EU-spec models.
- Protects Critical Exciter Components: — Shields the exciter motor from debris, moisture, and mechanical impact during operation; a missing or cracked cover exposes internal drive components to accelerated wear and contamination.
- Verified Part Number: — Sold under Wacker Neuson part number 5000111840, cross-referenced against multiple RD7 machine configurations for accurate sourcing.
The exciter housing motor cover serves as a protective enclosure over the exciter motor on the drum assembly of a tandem roller. The exciter motor drives the eccentric weights that generate the vibratory force transferred to the drums — this compaction force is what allows the roller to effectively densify asphalt and soil surfaces. When the cover is damaged, cracked, or missing, the exciter motor and surrounding components are exposed to road grit, water ingress, and physical damage, which can lead to premature motor failure and loss of drum vibration.
