Wacker Neuson 5100013390 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. As a factory-sourced part, it is manufactured to the same specifications as the original, ensuring a direct, like-for-like replacement across a wide range of Wacker Neuson compaction equipment. Fitment covers standard, canopy, open-ROPS, DPF, and electric-drive variants within these roller families, including US-market and generation-3 models. When your roller's hydraulic system needs restoring, the is the correct part to specify.

Key Features

• Genuine OEM Casting Integrity — Manufactured to Wacker Neuson's original dimensional and pressure tolerances, so the housing accepts mating hydraulic components without rework or shimming.
• Direct Bolt-On Replacement — Retains the factory port layout and mounting pattern, allowing straightforward installation into the existing hydraulic circuit.
• Broad Series Compatibility — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, covering standard, canopy, open-ROPS, DPF, and electric-drive configurations across multiple build generations.
• Sustained Hydraulic Performance — A sound pump housing maintains correct fluid containment and pressure transfer; a cracked or worn housing causes pressure loss, erratic drum vibration, and compaction inconsistency.
• Hydraulic System Safety — Proper housing integrity prevents uncontrolled fluid leaks that can create slip hazards and lead to sudden loss of drive or vibration function during operation.

The pump housing forms the structural outer body of the hydraulic pump assembly, enclosing the internal rotating components and maintaining the sealed fluid passages that generate and direct hydraulic pressure throughout the roller. It must withstand continuous high-pressure cycling and mechanical stress from the pump internals; a housing that is cracked, eroded, or damaged at its sealing faces will allow pressure to bleed off, resulting in weak or unresponsive drum drive and vibration output. Replacing a failed housing with the correct OEM part restores the pressure envelope the system depends on and brings the roller back to its rated compaction performance.
