The Wacker Neuson Pump Case Housing is a genuine OEM component designed for RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a direct factory replacement, this part meets the exact dimensional and material specifications of the original, ensuring the hydraulic pump assembly seats and seals correctly within the drivetrain. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components installed at the factory, making the the trusted choice when rebuilding or servicing the pump assembly on your RD27 roller.
Key Features
- Genuine OEM Structural Integrity — Machined to the original housing tolerances, ensuring the pump bore geometry and port alignment are correct for leak-free hydraulic operation.
- Direct Bolt-In Replacement — Matches the original mounting bolt pattern and port configurations, allowing the pump assembly to seat without rework or shimming.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 rollers across standard and traction control variants, covering a wide range of machine serial ranges.
- Hydraulic System Protection — A sound pump case housing maintains proper fluid containment and pressure integrity; a cracked or worn housing leads to hydraulic fluid loss and loss of drive or vibration function.
- Pressure-Rated for Hydrostatic Duty — Built to contain the operating pressures of a hydrostatic drive circuit, where housing failure can result in unsafe loss of machine propulsion.
The pump case housing forms the structural shell of the hydraulic pump assembly, enclosing the internal rotating components and providing the fluid-tight chamber necessary for pressure to build and flow to be directed through the hydrostatic drive circuit. On RD27 tandem rollers, the hydrostatic system controls both propulsion and drum vibration, so a compromised housing — whether cracked, eroded, or warped — can cause fluid leaks, pressure drop, and partial or complete loss of drive response. Replacing a damaged housing with a genuine OEM part restores the pump assembly to its correct operating condition and prevents secondary damage to the pump internals.
