The Wacker Neuson 5000010644 is a genuine OEM Lock Washer designed for the BS-series gasoline vibratory rammer lineup, covering a wide range of models including the BS50-2, BS60-2, BS70-2, BS62-2, BS68-2, BS65-V, and their respective variants. As a genuine OEM component, this Lock Washer is manufactured to the exact specification required by Wacker Neuson for proper fitment and function. Compatibility extends across both standard and "plus" variants, fuel-injected "i" models, and select regional and specialty configurations within the BS rammer family. Always verify your machine's model number before ordering to ensure this is the correct part for your unit.
Key Features
- Genuine OEM Specification: — Manufactured to the exact torque-retention and dimensional tolerances required for Wacker Neuson rammer assemblies, ensuring the washer seats and locks correctly under vibration-heavy operating conditions.
- Drop-In Replacement: — Matches the original Lock Washer in inner diameter, outer diameter, and tooth profile, so it installs directly in place of the worn or damaged component without any modification.
- Broad BS-Series Compatibility: — Verified for use across the BS50-2, BS50-2i, BS50-2plus, BS60-2, BS60-2i, BS60-2plus, BS62-2, BS65-V, BS68-2, BS70-2, BS70-2i, BS70-2plus, and additional BS rammer variants in both US and EU configurations.
- Vibration Resistance: — Lock washers on vibratory rammers are subjected to continuous high-frequency impact loads; this genuine OEM part maintains the clamping force needed to keep critical fasteners secure throughout the compaction cycle.
- Fastener Integrity: — A failed or omitted lock washer allows fasteners to back out under vibration, which can lead to component loosening, accelerated wear, and potential structural damage to the rammer — replacing a worn washer at service time is a low-cost step that protects higher-value components.
A lock washer is a small but essential hardware component placed under a bolt or nut to prevent it from loosening due to vibration or dynamic loads. On a vibratory rammer like the Wacker Neuson BS series, where the machine generates intense repetitive impact forces during trench and cohesive soil compaction, fasteners throughout the assembly are constantly exposed to loosening stress. The lock washer's toothed or spring-tension profile bites into both the fastener bearing surface and the mating component, maintaining clamping force and preventing rotation. When a lock washer becomes deformed, corroded, or loses its tension, fasteners can work loose — potentially causing misalignment, component damage, or unsafe operation of the machine.
