The Wacker Neuson is a genuine OEM Decompression Lever designed for a range of Wacker Neuson single-direction vibratory plates, reversible vibratory plates, and single-drum vibratory rollers — including the DPS3050, DPS3060, DPU 2870, DPU 2950, DPU 2960, DPU 2970, and RS800H. Sourced directly from Wacker Neuson, part carries the same specifications as the original component installed at the factory. This lever is a direct-fit replacement that installs without modification to the engine assembly, making it a straightforward service item for technicians and operators alike. If your machine is hard to pull-start or the decompression mechanism has become sticky, worn, or broken, replacing it with the correct OEM part restores proper engine starting behavior.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original design tolerances, ensuring the lever engages and releases compression at the correct stroke position for consistent, repeatable starting performance.
- Direct-Fit Replacement: — Engineered to bolt directly into the engine decompression assembly on compatible machines; no drilling, filing, or adapting required.
- Broad Fitment Coverage: — Confirmed fit across multiple Wacker Neuson compaction families, including DPS single-direction vibratory plates (DPS3050, DPS3060), DPU reversible vibratory plates (DPU 2870, DPU 2950, DPU 2960, DPU 2970), and the RS800H single-drum vibratory roller.
- Restores Easy Pull-Start: — A functioning decompression lever temporarily reduces cylinder pressure during cranking, allowing the engine to turn over freely and start with significantly less effort — critical during cold starts or after extended downtime.
- Verified Part Number Traceability: — Order with confidence knowing 5004101571 is the exact Wacker Neuson part number cross-referenced to your specific machine model, eliminating guesswork at the parts counter.
The decompression lever is a small but essential component in the engine starting system of gasoline-powered compaction equipment. When you pull the starter cord, the lever briefly opens a valve in the cylinder head to release built-up compression, reducing the resistance the engine presents to the starter mechanism and making it far easier to reach firing speed. Once the engine fires and begins running, the lever disengages automatically and the cylinder operates at full compression as normal. When this lever breaks, sticks, or wears out of adjustment, starting the machine can become extremely difficult or impossible — placing unnecessary strain on the recoil starter, the operator, and the engine itself.
