The Wacker Neuson 5100011486 is a genuine OEM O-Ring Seal designed for the RD40-130 and RD45-140 tandem roller series and the RC110 single-drum soil compactor series. As a factory-sourced component, this seal is manufactured to the exact material and dimensional specifications Wacker Neuson requires, ensuring a proper fit within the hydraulic or fluid system it serves. It covers an extensive range of configurations across both roller families, including standard, offset drum, combination, DPF, ROPS, cab, and US-market variants. Whether you are servicing a walk-behind tandem roller on an asphalt paving job or maintaining a large-area soil compactor, part number 5100011486 is the correct OEM replacement to restore the sealing integrity of your machine.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified elastomer compound, delivering the compression set resistance and chemical compatibility required for hydraulic fluid environments in heavy compaction equipment.
- Drop-In Replacement — Dimensioned to seat precisely in the original groove geometry, allowing reinstallation without reworking or adapting the surrounding components.
- Broad Series Coverage — Fits the full RD40-130 and RD45-140 tandem roller lineup plus the RC110 and RC110p single-drum compactor range, including DPF, ROPS, CAB, and US-market configurations.
- Leak Prevention — A correctly seated O-Ring Seal maintains system pressure and prevents fluid loss that would otherwise lead to hydraulic performance degradation or contamination of surrounding components.
- Fluid System Integrity — Using the OEM-specified seal compound ensures compatibility with Wacker Neuson-approved hydraulic fluids, reducing the risk of seal swell, cracking, or premature failure.
An O-Ring Seal creates a static or dynamic fluid-tight barrier between mating components in a hydraulic or fluid circuit. In compaction equipment like the RD40-130, RD45-140, and RC110 series, these seals are critical to maintaining the hydraulic pressure that drives drum vibration, propulsion, and steering functions. When an O-Ring Seal deteriorates — through heat cycling, chemical exposure, or compression set — it allows fluid to bypass or leak out, causing sluggish machine response, visible external leaks, and potential damage to downstream components. Replacing a worn seal promptly with the correct OEM part restores system integrity and keeps the machine performing at its designed output.
