The Wacker Neuson 5100046509 is a genuine OEM Fuel Tank Cap designed for the RTLx-SC3, RTKx-SC3, RTL82-SC3, and RTK82-SC3 series remote-controlled trench rollers. As a factory-sourced component, the 5100046509 delivers the exact fit and sealing performance specified for these machines during original production. This cap is confirmed compatible across multiple machine configurations within the RTx-SC3 and RTx-SC2 trench roller families, including Compatec-equipped variants and the HTC15. Keep a verified OEM replacement on hand so fuel system integrity is never compromised between service intervals.
Key Features
- OEM-Specified Seal Integrity — Manufactured to the exact thread pitch and seal compression rating of the original cap, preventing fuel vapor escape and contamination ingress at the tank opening.
- Drop-In Fitment Across RTx-SC3 Variants — Threads directly onto the factory fuel tank neck on RTLx-SC3, RTKx-SC3, RTL82-SC3, RTK82-SC3, and RTx-SC2 EU trench rollers with no modification to the tank or filler neck.
- Broad Series Compatibility — A single part number covers a wide range of SC3-generation trench roller configurations, including standard, green, Compatec-equipped, and multi-color variants, simplifying parts procurement for mixed fleets.
- Fuel System Protection — A properly sealed tank cap prevents dirt, debris, and moisture from entering the fuel supply, protecting the engine and fuel system components from contamination-related wear.
- Fuel Safety Compliance — A secure, OEM-grade cap is essential for controlling fuel vapors and preventing spills on active jobsites — particularly relevant for diesel-powered remote-controlled equipment operating near open trenches.
The fuel tank cap seals the opening of the machine's fuel tank, maintaining a closed fuel system between refueling intervals. A correctly functioning cap holds a consistent seal that keeps contaminants out and prevents fuel vapors from venting freely into the surrounding environment. When a cap is cracked, has a degraded seal, or is missing entirely, the machine becomes vulnerable to fuel contamination, accelerated engine wear, and potential fire or environmental hazard — making timely replacement of this small but critical component essential to safe, continuous operation.
