The Wacker Neuson 5100011962 is a genuine OEM Adjustment Bar designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement sourced from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. Fitment spans the full RD40-130 and RD45-140 model families, including standard, C (combination), O (open drum), DPF, and.3-variant configurations across US and international machines. If your walk-behind or ride-on tandem roller is showing wear or misadjustment issues, part number 5100011962 is the correct replacement to restore proper operation.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact dimensional and material tolerances, ensuring the adjustment bar engages and positions correctly within the roller's mechanical linkage without play or slop.
- Drop-In Replacement: — Matches the original mounting points and geometry of the factory-installed bar, so installation follows standard service procedures without custom fitting or modification.
- Broad RD-Series Compatibility: — Verified for the complete RD40-130 and RD45-140 tandem roller families, including DPF emissions variants, C and O drum configurations, and .3-series updates.
- Restores Precise Mechanical Control: — A worn or bent adjustment bar compromises the operator's ability to maintain consistent drum positioning and compaction pressure, leading to uneven asphalt or soil passes. Replacing it brings control response back to spec.
- Long-Term Structural Integrity: — Built from materials matched to the demands of continuous vibratory compaction cycles, resisting fatigue and deformation over extended service intervals.
The adjustment bar is a mechanical component within the tandem roller's control or drum-positioning system, responsible for setting and maintaining the correct alignment or tension across linked assemblies during operation. When this bar wears, bends, or breaks, the operator loses the ability to make accurate adjustments, which can result in inconsistent compaction passes, increased machine stress, and the need for rework on the finished surface. Replacing a failed adjustment bar promptly keeps the roller operating predictably and protects the integrity of the surrounding linkage components.
