The Wacker Neuson 5100022906 is a genuine OEM Filler Cap designed for the RC50 and RC70 series single drum soil compactors. As a factory-original component, it is manufactured to the same specifications as the part it replaces, ensuring a secure, leak-free seal on the fluid reservoir it services. This cap fits across the full RC50 and RC70 model range, including padfoot and smooth drum variants in both standard and US configurations. Verify your machine's model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Integrity — Factory-original cap material and thread specification maintain a positive, pressure-rated seal to prevent fluid contamination and leakage.
- Direct Thread-On Replacement — Matches the original cap's thread pitch and diameter for a straightforward swap with no reworking of the filler neck.
- Broad RC-Series Compatibility — Fits the full RC50 and RC70 single drum soil compactor lineup, covering smooth drum, padfoot, and vibration roller variants in both standard and US-spec configurations.
- Contamination Protection — A correctly seated filler cap keeps dirt, debris, and moisture out of the fluid system, preserving fluid quality and protecting downstream components.
- Fluid System Safety — A worn or missing filler cap can result in fluid loss or ingestion of contaminants, leading to accelerated wear or system failure on a working compactor.
The filler cap seals the fluid reservoir access point on the machine, preventing the escape of fluid during operation and blocking the entry of dirt, water, and other contaminants when the machine is at rest or in transit. On a heavy-duty soil compactor like the RC50 and RC70 series, maintaining a clean, sealed fluid system is critical to protecting hydraulic or engine components from premature wear. A cracked, missing, or poorly sealing cap can allow particulate ingestion that shortens the service life of the entire system it feeds.
