Wacker Neuson 5100012967 Locking Washer

The Wacker Neuson 5100012967 is a genuine OEM Locking Washer designed for the RD and RC series of tandem rollers and single-drum soil compactors, covering an extensive range of models including the RD18, RD24, RD27, RD28, RD40, RD45, RC50, RC70, and RC110 families. As a genuine OEM component, part 5100012967 is manufactured to the exact specifications required by Wacker Neuson, ensuring a direct, hassle-free installation with no guesswork on fitment. This Locking Washer is verified across a broad range of configurations including cab, ROPS, DPF, and open-station variants within these roller and compactor series. Keeping this small but critical fastener in good condition protects threaded connections throughout the machine and helps maintain the structural integrity that heavy compaction work demands.

Key Features

• Genuine OEM Specification: Manufactured to Wacker Neuson's exact hardness and dimensional tolerances for Locking Washers, ensuring proper clamping force and thread retention under the vibration loads generated by roller and compactor operation.
• Direct-Fit Replacement: Engineered to seat and lock exactly as the original, with no reworking of mating fasteners or hardware required during installation.
• Broad RD and RC Series Coverage: Confirmed fitment across RD18, RD24, RD27, RD28, RD40, RD45 tandem roller variants and RC50, RC70, and RC110 single-drum soil compactor variants, including cab, ROPS, DPF, and open configurations.
• Vibration-Resistant Locking Action: Locking Washers in compaction equipment are subjected to constant high-frequency vibration; a worn or missing washer allows fasteners to back out, leading to loosened assemblies and accelerated component wear.
• Safety-Critical Fastener Integrity: On rollers and compactors, loose fasteners caused by failed locking hardware can compromise drum, frame, and drivetrain connections — replacing worn Locking Washers is a straightforward step that protects operator safety and machine reliability.

A Locking Washer is a small but essential fastener component that prevents bolts and nuts from loosening under vibration and dynamic loading. In tandem rollers and single-drum soil compactors like the RD and RC series, machine frames, drum assemblies, and drivetrain components are exposed to intense, continuous vibration during operation. The Locking Washer creates a mechanical resistance against rotation that keeps threaded fasteners secured in place through these demanding conditions. When a Locking Washer becomes flattened, cracked, or corroded, it loses its ability to maintain clamp load — allowing fasteners to back out gradually, which can lead to component loosening, misalignment, or structural damage if left unaddressed.
