Wacker Neuson 5100013389 Pump Housing

The Wacker Neuson Pump Housing is a genuine OEM component designed for the RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers, covering standard, canopy, open-ROPS, DPF, and electric-drive variants across multiple production generations. As a direct OEM replacement, part is manufactured to the same tolerances and material specifications as the original, ensuring a drop-in installation without adaptation. Compatibility extends across a broad range of Wacker Neuson tandem roller configurations, including US-market, SE-market, and.3-series models, making this a versatile stock item for fleets running multiple roller variants. Verify your machine's serial number against the fitment list before ordering to confirm this is the correct housing for your specific unit.

Key Features

• Precision-Matched Housing Geometry — Manufactured to OEM dimensional tolerances, maintaining correct fluid passages and port alignment critical for stable hydraulic pump output.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same casting and material grade as the original production component.
• Direct-Fit Replacement — Mounts to the existing pump assembly using original fastener positions and sealing surfaces, requiring no machining or rework of the pump circuit.
• Broad Series Coverage — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, including canopy, open-ROPS, DPF, electric, and multi-generation .3-series configurations.
• Structural Integrity Under Pressure — A sound pump housing contains operating pressures within the hydraulic circuit; a cracked or worn housing causes pressure loss, erratic drum drive response, and potential hydraulic fluid leakage.

The pump housing is the structural shell that encloses the internal components of the hydraulic pump — holding the rotating assembly in precise alignment while containing the high-pressure hydraulic fluid that drives the roller's drum and propulsion circuits. It provides the sealed environment the pump needs to build and sustain operating pressure; without it, the pump cannot move fluid efficiently through the system. When a pump housing cracks, corrodes, or develops worn sealing surfaces, the result is hydraulic pressure loss, heat buildup, and progressive damage to the pump internals — making prompt replacement essential to keeping the roller's compaction performance consistent.
