The Wacker Neuson 5100023049 is a genuine OEM Filler Cap designed for the RC50, RC70, and RC110 series single-drum soil compactors. As a direct OEM replacement, this cap is manufactured to the same specifications as the original, ensuring a correct, secure fit on all covered RC-series machines. Fitment spans the full RC compactor lineup, including padfoot and smooth-drum variants, CAB and ROPS configurations, and both standard and US-market models across the RC50, RC70, and RC110 families.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original specification, this filler cap delivers the same thread engagement, seal compression, and pressure retention as the factory-installed unit.
- Direct Drop-In Replacement — Threads directly onto the original filler neck without modification, restoring proper closure to the fluid system on first installation.
- Broad RC-Series Compatibility — Covers RC50, RC50p, RC70, RC70p, RC70vo, RC110, and RC110p models in standard, padfoot, CAB, ROPS, and US-market configurations.
- Prevents Contamination and Fluid Loss — A properly seated filler cap keeps dirt, debris, and moisture out of the fluid system, protecting internal components and maintaining correct fluid levels during operation.
- Fuel and Fluid System Safety — A failed or missing filler cap on a large soil compactor creates a spill and fire risk; replacing it promptly with a verified OEM part maintains safe machine operation on the worksite.
A filler cap seals the fluid fill port on the machine, preventing contaminants such as dirt, dust, and water from entering the tank or reservoir during operation and transport. On large soil compactors like the RC-series, maintaining a secure seal at the fill point is critical to protecting the hydraulic or fuel system from premature wear and costly internal damage. When a filler cap cracks, strips, or goes missing, the open port exposes the fluid system to contamination and allows fluid to escape — leading to system faults or damage if left unaddressed.
