The Wacker Neuson Stud Bolt is a genuine OEM component designed for the RD45-140 series tandem rollers, including the RD45-140, RD45-140 C, and RD45-140 O variants across standard, US, and DPF-equipped configurations. As a factory-sourced part, is manufactured to the same tolerances and material specifications as the original hardware installed at the factory. This stud bolt fits across the full RD45-140 model family, making it a straightforward replacement for worn, damaged, or missing fastener hardware on these machines.
Key Features
- OEM Thread and Material Specification — Manufactured to exact thread pitch, shank diameter, and material grade as the original factory-installed stud bolt, ensuring correct clamping load and joint integrity.
- Drop-In Replacement Hardware — Installs directly into existing threaded bores without rework, reaming, or thread chasing required on properly maintained machines.
- Broad RD45-140 Series Coverage — Compatible with RD45-140, RD45-140 C, RD45-140 O, RD45-140.3, RD45-140c.3, RD45-140o.3, and DPF-equipped variants in both standard and US configurations.
- Maintains Fastener Joint Integrity — A correctly spec'd stud bolt holds critical assemblies under the vibration and dynamic load cycles typical of compaction roller operation, preventing loosening and structural fatigue.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so part number 5100012947 matches the original bill of materials for your machine.
A stud bolt is a fully threaded or partially threaded fastener used to clamp two or more components together, typically by threading into one mating surface and securing with a nut on the exposed end. On compaction rollers like the RD45-140 series, stud bolts are used in high-vibration assemblies where reliable, repeatable clamping force is critical to keeping structural and mechanical joints secure during operation. When a stud bolt is damaged, stretched beyond its yield point, or threads are compromised, the affected joint can loosen progressively under load, leading to misalignment, component wear, or assembly failure that requires more extensive repair.
