The Wacker Neuson Stud Bolt is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. As a factory-sourced part, this stud bolt is manufactured to the same specifications as the original hardware installed at the plant, ensuring a direct, trouble-free installation. Compatibility spans the full RD40-130 and RD45-140 model range, including standard, C, O, and.3 variants — making the correct choice across a broad family of Wacker Neuson tandem rollers.
Key Features
- OEM Thread Integrity — Manufactured to original torque and thread specifications, so the stud seats and clamps correctly without stripping or misalignment.
- Direct Hardware Replacement — Matches the original stud geometry and length exactly, dropping into place without rework or additional hardware.
- Broad RD Series Fitment — Fits RD40-130 and RD45-140 series tandem rollers across standard, C (canopy), O (operator platform), and .3 generation variants.
- Structural Holding Power — A correctly functioning stud bolt maintains the clamping load that keeps critical assemblies secured under the vibration and load cycles of compaction work; a worn or damaged stud can lead to joint loosening and component damage.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so part number 5100012304 is verified against current factory documentation.
A stud bolt is a fully threaded fastener with no head, designed to be permanently anchored into one component while a nut is drawn down on the exposed end to clamp a second component in place. On compaction rollers like the RD40-130 and RD45-140, stud bolts are used in high-stress joint locations where a conventional bolt and nut arrangement is impractical or where repeated assembly and disassembly is required. When a stud bolt becomes corroded, stretched, or damaged, it can no longer maintain the correct clamping force, which puts surrounding components — and the integrity of the joint — at risk. Replacing it promptly with the correct OEM part restores the connection to its original holding strength.
