The Wacker Neuson 5100011839 is a genuine OEM Centre Pivot Assembly designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement, part 5100011839 is manufactured to the same tolerances and specifications as the original component, ensuring a correct, drop-in installation with no guesswork. This assembly fits an extensive range of RD40-130 and RD45-140 variants, including standard, combination (C/O), DPF, and.3-series configurations across both US and international builds. Keeping this critical articulation component in good condition is essential to maintaining steering precision and safe roller operation on asphalt and soil compaction sites.
Key Features
- Genuine OEM Construction: — Manufactured to the same material and dimensional tolerances as the original pivot assembly, ensuring correct load-bearing capacity and articulation geometry at the roller's center joint.
- Broad RD Series Compatibility: — Fits the full RD40-130 and RD45-140 tandem roller families, covering standard, C, O, DPF, and .3-series variants in both US and international configurations.
- Direct Replacement Fit: — Engineered to match the original mounting interfaces, so installation aligns with the existing frame pivot points without rework or additional hardware.
- Steering and Articulation Integrity: — A worn or damaged centre pivot assembly causes sloppy or unresponsive steering on the roller; replacing it restores precise articulation control essential for straight, accurate compaction passes.
- Operational Safety: — The centre pivot is a structural articulation point under constant load; using a correctly rated OEM assembly maintains the structural integrity of the roller's steering system and supports safe operation.
The centre pivot assembly is the mechanical joint at the articulation point between the front and rear frames of a tandem roller. It allows the machine to steer by enabling the two frame sections to pivot relative to each other during operation. This joint carries significant dynamic and static loads during compaction passes, and wear or failure at this point results in loose, imprecise steering, uneven drum tracking, and potential loss of directional control. Replacing a worn centre pivot assembly promptly restores full articulation response and keeps the roller tracking accurately across the compaction surface.
