The Wacker Neuson 5100046545 is a genuine OEM Gerotor Housing Kit designed for the RD7, RD7A, RD7H, and RD7Ye walk-behind tandem roller series. Sourced directly from Wacker Neuson, this kit delivers the exact fit and material specification required by the hydraulic system on these machines. Fitment covers a wide range of RD7-family tandem rollers, including RD7A, RD7H, RD7He, and RD7Ye variants. Keeping the gerotor housing in proper working condition is critical to maintaining hydraulic pressure and drive performance on the job.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to Wacker Neuson's exact tolerances for the gerotor circuit, ensuring correct displacement and pressure characteristics within the hydraulic system.
- Direct-Fit Replacement — Engineered to drop into the existing hydraulic assembly on RD7-series tandem rollers without modification to surrounding components.
- Broad RD7 Family Coverage — Compatible with RD7, RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, making this kit a reliable stock item for fleets running multiple RD7 configurations.
- Hydraulic System Integrity — A failed or worn gerotor housing causes loss of hydraulic flow and drive response; replacing it with this OEM kit restores full system output and smooth roller operation.
- Complete Kit Format — Supplied as a full housing kit with the necessary components to complete the repair, reducing the need for multiple separate part orders.
The gerotor housing is a core component of the hydraulic motor or pump assembly on walk-behind tandem rollers. It forms the precision-machined cavity in which the gerotor gear set rotates to generate and direct hydraulic flow, controlling drum drive and compaction force. When the housing wears, becomes scored, or develops internal leakage paths, hydraulic efficiency drops — resulting in sluggish drum response, uneven compaction output, or a complete loss of drive. Replacing the housing with a correctly specified OEM kit restores the sealed geometry the gerotor set needs to operate at full efficiency.
