The Wacker Neuson Governor Spring is a genuine OEM component designed for the RS800H single drum vibratory roller, DPS3050, DPS3060 single-direction vibratory plates, and DPU 2870, DPU 2950, DPU 2960, and DPU 2970 reversible vibratory plates. As a direct factory replacement, this spring meets the same tension and load specifications as the original part, ensuring the engine governor responds correctly under varying compaction loads. It fits across the DPS and DPU plate compactor families, making it a versatile service item for operators running multiple Wacker Neuson machines on the same fleet.
Key Features
- Calibrated Spring Tension: — Engineered to the OEM load rating so the governor arm returns to position accurately, maintaining correct engine speed response across the RPM range.
- Drop-In Replacement: — Matches the original hook geometry and coil dimensions for direct installation onto the governor linkage without reworking the assembly.
- Broad Fleet Coverage: — Fits the RS800H single drum roller, DPS3050 and DPS3060 single-direction plates, and DPU 2870, DPU 2950, DPU 2960, and DPU 2970 reversible plate compactors.
- Engine Speed Stability: — A correctly tensioned governor spring keeps engine RPM consistent under compaction load, delivering even centrifugal force and predictable compaction depth pass after pass.
- Genuine OEM Sourcing: — Supplied as a genuine Wacker Neuson part under part number 5004102181, backed by the same quality controls applied to every component on the original production line.
The governor spring is a critical link in the engine's mechanical speed-control system. It applies a return force on the governor lever, balancing centrifugal flyweight force to hold engine RPM at the set operating speed. When the spring weakens, stretches, or breaks, the governor loses its ability to regulate engine speed accurately — the engine may hunt, surge, or fail to reach full power under load. On a vibratory plate or roller, this directly affects compaction output and can cause uneven results across a pass. Replacing a worn or fatigued governor spring restores proper speed regulation and brings engine performance back to specification.
