Wacker Neuson 5000155486 Throttle Actuator

The Wacker Neuson is a genuine OEM Throttle Actuator designed for a broad range of Wacker Neuson tandem rollers, trench rollers, and reversible vibratory plate compactors. As a direct OEM component, the is manufactured to the same specification as the original part, ensuring correct fitment and consistent engine response across compatible machines. Verified fitment covers RD12-90, RD16-90, RD16-100, RD27-100, and RD27-120 tandem rollers, RT56-SC, RT82-SC, RT82-SC2, RTx-SC2, RTLx-SC3, RTKx-SC3, and RTK82-SC3 trench rollers, as well as DPU 80, DPU 90, and DPU 110 series reversible vibratory plate compactors. Always confirm your machine's model and serial number against the fitment list before ordering.

Key Features

• Genuine OEM Electrical Accuracy — Sourced directly from Wacker Neuson, this actuator meets the original output and signal specifications required for precise throttle control on compatible engines.
• Direct Drop-In Replacement — Engineered to match the original mounting points and connector interface, the 5000155486 installs in place of the worn or failed unit without modification to the wiring harness or throttle linkage.
• Broad Cross-Family Fitment — Compatible across RD tandem rollers, RT/RTL/RTK/RTx trench roller families, and DPU reversible plate compactor series, making this a high-utility stocking part for mixed fleets.
• Consistent Engine Speed Management — A correctly functioning throttle actuator maintains the engine speed settings commanded by the operator or control system; a failed unit can cause erratic speed, loss of compaction force, or inability to reach operating RPM.
• Fuel System Safety — As a component in the engine throttle and fuel control circuit, a properly seated OEM actuator ensures the engine responds correctly to shutdown and run commands, reducing the risk of unintended engine behavior.

The throttle actuator is an electromechanical component that translates electrical control signals from the machine's engine management or operator controls into physical movement of the throttle mechanism, regulating engine speed and fuel delivery. On compaction equipment, accurate throttle control is critical — it governs the power available to the vibration system and drive, directly affecting compaction output and gradeability. When the actuator wears out or fails, symptoms typically include unstable idle, inability to reach full operating RPM, sluggish throttle response, or in some cases, the engine defaulting to a limp or shutdown state.
