The Wacker Neuson Locking Screw is a genuine OEM component designed for the RD40-130 and RD45-140 series double drum rollers, including standard, open drum, and.3 generation variants. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original hardware installed at the factory. Confirmed fitment spans the full RD40-130 and RD45-140 model families, covering both standard and open drum configurations across multiple production series.
Key Features
- OEM Thread and Torque Specification — Manufactured to the precise thread profile and engagement depth of the original, ensuring the screw locks and holds as intended without stripping or backing out under vibration.
- Direct Hardware Replacement — Drops straight into the existing threaded bore with no chasing, reworking, or adapting required — ready to install with standard tooling.
- Broad RD Series Fitment — Compatible across RD40-130 and RD45-140 model families, including standard, open drum, and .3 generation variants, covering a wide range of machines from a single part number.
- Vibration-Resistant Locking Function — A correctly seated locking screw keeps critical assemblies secured during compaction cycles; a worn or missing screw can allow components to shift under load, affecting compaction output and creating further wear.
- Genuine Wacker Neuson OEM Part — Supplied as a genuine OEM item under part number 5100067851, so you are getting the same hardware specified by Wacker Neuson for these machines — not an approximation.
A locking screw is a threaded fastener whose primary job is to secure a component in a fixed position and prevent it from rotating, sliding, or loosening under operational stress. On double drum rollers like the RD40-130 and RD45-140 series, equipment is subjected to continuous vibration and impact forces during compaction, which places constant stress on every fastener in the assembly. When a locking screw wears out, backs off, or fails, the component it was holding can shift or come free, leading to accelerated wear on surrounding parts and potentially causing more significant mechanical damage if left unaddressed.
