The Wacker Neuson 5100012183 is a genuine OEM Hexagon Nut designed for the RD40-130 and RD45-140 series tandem rollers. As a factory-sourced component, the 5100012183 meets the exact material and dimensional specifications used in original production, ensuring a correct fit in service. This Hexagon Nut is compatible across a wide range of RD40-130 and RD45-140 variants, including standard, combination, and open-drum configurations produced across multiple build series.
Key Features
- Genuine OEM Material Grade — Sourced directly from Wacker Neuson, this Hexagon Nut is manufactured to the same alloy grade, thread pitch, and torque rating as the part installed at the factory.
- Exact Thread Engagement — Engineered to the original thread specification, this nut seats and torques correctly without the risk of cross-threading or undertorque associated with mismatched hardware.
- Broad RD-Series Compatibility — Confirmed fitment across RD40-130 and RD45-140 tandem roller variants, including standard, C (combination), and O (open drum) configurations across US and international build series.
- Structural Integrity Under Compaction Loads — Tandem rollers transmit significant vibration and compaction forces through their frames; a correctly rated Hexagon Nut maintains clamping force under these dynamic loads, preventing fastener loosening during operation.
- Direct Service Replacement — Replaces the original hardware with no re-drilling, re-tapping, or adaptation — install with standard hand tools as part of a scheduled service or repair.
A Hexagon Nut is a standard threaded fastener used throughout the structural and mechanical assemblies of a tandem roller to clamp components securely together. On machines like the RD40-130 and RD45-140 series, fasteners are subjected to constant vibration from dual-drum compaction cycles, which places repeated stress on clamping joints. A worn, damaged, or incorrect nut can lose its clamping load over time, leading to loose assemblies, accelerated wear on mating components, and potential mechanical failure if left unaddressed.
