Wacker Neuson 5000058381 Lockwasher

The Wacker Neuson Lockwasher is a genuine OEM component designed for the BS50-2, BS60-2, BS70-2, BS65-V, BS70-2i, DS70, and DS720 vibratory rammer series, along with a wide range of additional Wacker Neuson compaction and demolition equipment. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original hardware installed at the factory — no guesswork on sizing, thread engagement, or material grade. This Lockwasher fits an extensive range of rammer models across multiple generations, making it a dependable stock item for rental fleets, service shops, and contractors managing multiple machines. Confirm your machine number against the fitment list to ensure the correct application.

Key Features

• Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring proper locking force without distorting mating threads or fastener heads.
• Drop-In Hardware Replacement — Matches the original washer's inner diameter, outer diameter, and bite profile exactly, so it seats and functions correctly without reworking fastener assemblies.
• Broad Rammer Family Coverage — Verified fitment across BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS65-V, DS70, DS720, and legacy BS500/BS600/BS700 series rammers, plus select BH-series gasoline breakers and DPU reversible vibratory plates.
• Prevents Fastener Back-Out Under Vibration — Vibratory rammers generate continuous high-frequency shock loads that can loosen standard hardware; a correctly rated lockwasher maintains clamp load and prevents critical fasteners from walking loose during operation.
• Safety-Critical Fastening Application — Loose hardware on a vibratory rammer can lead to structural failure or loss of a major assembly during use; replacing worn or deformed lockwashers at every service interval is a straightforward step that protects both the operator and the machine.

A lockwasher is a hardened fastening component placed beneath a bolt or nut to resist rotational loosening caused by vibration and dynamic loading. On vibratory rammers — where the entire machine cycles at high frequency with every stroke — standard flat washers provide no resistance to fastener back-out, making lockwashers essential at key structural and drivetrain attachment points. When a lockwasher becomes deformed, corroded, or is omitted during reassembly, the fastener it supports can progressively loosen, leading to increased play in assemblies, accelerated wear on mating components, and in severe cases, complete fastener loss and unplanned disassembly of the machine in the field.
