The Wacker Neuson 5100011677 is a genuine OEM Coupling designed for the RD18-80 and RD18-100 series tandem rollers. As a factory-sourced component, this coupling is manufactured to the exact specifications required for proper drivetrain function across the full RD18 model family, including standard, US, SE, and.3-revision variants. Keeping the correct coupling in service ensures smooth, uninterrupted power transfer between drive components — critical for consistent compaction performance on asphalt and soil. Confirm your machine's model number before ordering to ensure an accurate match.
Key Features
- Genuine OEM Construction: — Manufactured to exact tolerancing for the RD18 drivetrain, ensuring proper engagement geometry and torque capacity that aftermarket alternatives may not replicate.
- Direct Drop-In Replacement: — Engineered to align with existing mounting points and mating components on RD18-80 and RD18-100 machines, so installation follows standard service procedures.
- Broad RD18 Series Coverage: — Fits RD18-80, RD18-80.3, RD18-100, RD18-100.3, RD18-100c, RD18-100c.3, and corresponding US and SE variants under a single part number.
- Sustained Power Transfer: — A worn or damaged coupling causes drivetrain slippage, vibration, and loss of traction to the drum — replacing it restores full, consistent compactive effort to the roller.
A coupling is a mechanical connector that links two rotating shafts or drive components, transmitting torque from one to the other while accommodating minor misalignment during operation. In a tandem roller like the RD18 series, the coupling plays a key role in delivering power from the engine or hydraulic drive system to the drum or propulsion assembly. When a coupling wears, cracks, or fails, the result is reduced drive efficiency, abnormal vibration, and in severe cases a complete loss of drum or wheel drive — bringing compaction operations to a halt and potentially causing secondary damage to connected components.
