The Wacker Neuson is a genuine OEM Washer A5 Lock Ext Blk Zinc 8T designed for the BS50, BS60, and BS70 series gasoline vibratory rammers. As a factory-sourced component, part is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct, consistent fit within the fastener assembly. This lock washer is confirmed across a wide range of BS-series rammer configurations, including 4s, 4As, and 4-stroke variants with 280mm/11-inch shoe setups. Whether you are performing routine maintenance or a targeted repair, sourcing the correct OEM hardware helps maintain the structural integrity of your rammer.
Key Features
- Black Zinc Coating for Corrosion Resistance — The Blk Zinc 8T finish provides a protective layer against moisture and oxidation, extending the service life of this fastener hardware in field conditions.
- External Tooth Lock Design — The external tooth profile bites into mating surfaces under torque load, resisting loosening caused by the high-frequency vibration inherent to rammer operation.
- Broad BS-Series Compatibility — Fits a wide range of Wacker Neuson BS50, BS60, and BS70 vibratory rammer models across 4s, 4As, and standard 4-stroke configurations, including high-altitude variants.
- Genuine OEM Hardware — Sourced directly from Wacker Neuson, part 5000164907 matches the original dimensional and material grade specifications, so fastener torque values and clamping loads remain consistent with the original assembly.
- Drop-In Replacement — This washer installs identically to the original, requiring no modification to adjacent fasteners, brackets, or housings.
A lock washer serves a straightforward but critical role in any bolted assembly: it prevents fasteners from backing out under load. In a vibratory rammer — a machine whose entire operating principle is sustained high-frequency impact — standard flat washers can allow bolts to loosen over time, leading to play in components, accelerated wear on mating surfaces, and potential structural failure. The external tooth design of this A5-grade washer grips both the bolt head and the substrate, maintaining clamping force even under continuous vibration. When this washer wears, deforms, or is omitted during reassembly, fasteners in the affected joint become vulnerable to self-loosening, which can compromise the performance and safety of the rammer over time.
