The Wacker Neuson is a genuine OEM Rocker Arm designed for the RD27-100 and RD27-120 series Hydrostatic Vibratory Rollers, including standard and Traction Control configurations. As a factory-sourced component, it is manufactured to the same specifications as the original part installed at the time of production, ensuring a correct fit within the engine's valvetrain. This part covers multiple machine configurations across the RD27 tandem roller family, making it the go-to replacement for operators running either drum-width variant.
Key Features
- Factory-Matched Valvetrain Geometry — Manufactured to OEM specification, this rocker arm maintains the correct pivot ratio and contact geometry for consistent valve lift across the engine's operating range.
- Direct Engine Drop-In — Engineered to seat on the rocker shaft and engage the valve stem and pushrod exactly as the original, with no machining or modification needed during installation.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 Hydrostatic Vibratory Rollers, including both standard and Traction Control variants.
- Protects Engine Timing and Power Output — A worn or damaged rocker arm causes erratic valve actuation, leading to misfires, loss of compression, and uneven engine performance that directly impacts drum vibration and compaction consistency.
- Genuine OEM Sourcing — Sourced directly through the Wacker Neuson parts network, this component carries the same part number — 5000161371 — used by authorized dealers and service centers worldwide.
The rocker arm is a critical component in the engine's valvetrain, translating the upward push of the camshaft-driven pushrod into the downward motion needed to open intake and exhaust valves at precisely the right moment. On a tandem roller like the RD27, consistent engine performance directly affects drum speed, vibration frequency, and compaction output — so a properly functioning rocker arm is essential to getting the results you need from the machine. When a rocker arm wears or fails, symptoms typically include ticking or tapping noises from the valve cover area, rough idle, reduced power, or a cylinder that stops firing altogether.
