The Wacker Neuson 5100058381 is a genuine OEM Lock Washer designed for Wacker Neuson BS series gasoline vibratory rammers and DPS series compaction equipment. As a direct factory replacement sourced through Wacker Neuson's authorized parts program, the 5100058381 is manufactured to the same tolerances and material specifications as the original component installed at the factory. This Lock Washer fits a wide range of BS rammer models including the BS 45Y, BS 50-2, BS 50-2i, BS 52Y, BS 500, BS 500S, BS 500-oi, BS 60-2, BS 60-2i, BS 600, BS 600S, BS 600-oi, BS 60Y, BS 65-V, BS 70-2, BS 70-2i, BS 700, and the DPS 1850H, making it a highly versatile fastener component across multiple rammer generations. Verify your model and machine number against the fitment list before ordering to ensure correct application.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's material and hardness specifications, ensuring the locking tension and thread engagement this fastener application demands.
- Drop-In Replacement — Matches the original Lock Washer in bore diameter, outer diameter, and thickness so it seats correctly without rework or modification to mating hardware.
- Broad Rammer Family Fitment — Compatible with BS 45Y through BS 70-2i gasoline rammers and the DPS 1850H, covering a wide span of Wacker Neuson jumping jack and rammer generations.
- Maintains Fastener Integrity — A correctly functioning Lock Washer prevents critical fasteners from backing out under the intense vibration loads generated during trench and cohesive soil compaction cycles.
- Cost-Effective Preventive Maintenance — Replacing worn or deformed Lock Washers during scheduled service intervals protects more expensive mating components from damage caused by loose fasteners.
A Lock Washer is a hardened fastening component placed beneath a nut or bolt head to resist loosening caused by vibration, shock loads, and dynamic forces. In a vibratory rammer like the BS series, the machine's operating cycle generates continuous high-frequency impacts that place exceptional stress on every threaded connection in the assembly — a worn, flattened, or missing Lock Washer allows fasteners to gradually back out, leading to component movement, accelerated wear, and potential mechanical failure. Replacing the Lock Washer at the correct service interval keeps fastened joints secure and protects the surrounding hardware from the damage that loose connections cause over time.
