The Wacker Neuson is a genuine OEM Valve Spring designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a genuine Wacker Neuson part, the is manufactured to the same specifications as the original component installed at the factory, ensuring a direct, correct-fit replacement every time. This Valve Spring is compatible across multiple RD27 series machine numbers, covering a wide range of RD27-100 and RD27-120 units in active service. When your RD27 roller needs a valve spring, sourcing the genuine OEM part means no guesswork on fitment or function.
Key Features
- OEM Spring Rate Accuracy — Manufactured to the exact tension specification of the original, maintaining proper valve actuation force in the hydraulic or engine system.
- Drop-In Replacement — Matches the original spring geometry and seat dimensions for a direct swap with no reworking of surrounding components.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 tandem roller models across both standard and traction control variants.
- Sustained Valve Response — A correctly tensioned valve spring ensures consistent opening and closing cycles, preventing valve float, pressure loss, or sluggish system response.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000161477 carries full OEM traceability for service recordkeeping.
A valve spring holds a valve in its closed position and provides the return force needed to reseat the valve after each actuation cycle. Whether located in the engine valve train or within a hydraulic valve body, the spring must maintain consistent tension over thousands of cycles to keep timing, pressure, and flow control accurate. When a valve spring weakens, cracks, or breaks, valves may fail to close fully or return slowly, leading to pressure bleed-off, misfiring, or erratic system behavior — all of which directly impact the compaction output and drivability of the RD27 roller.
