The Wacker Neuson 5000172305 is a genuine OEM Lock Nut designed for the BS50-2, BS50-2i, BS60-2, BS60-2i, BS65-V, BS70-2, BS70-2i, MS52, and MS62 gasoline vibratory rammer series. As a direct OEM replacement sourced from Wacker Neuson, this lock nut meets the same specifications as the original hardware installed at the factory. It fits across a wide range of BS-series rammer configurations, including EU and "i" variants, making it a versatile stocking part for crews running multiple rammer models. Confirm your machine's model number before ordering to ensure correct fitment.
Key Features
- Genuine OEM Torque Retention: — Manufactured to Wacker Neuson's original thread and hardness specifications, ensuring the nut holds clamping force under the high-vibration loads generated by rammer operation.
- Drop-In Hardware Replacement: — Matches the original thread pitch and dimensions so it installs directly onto the existing fastener position without chasing threads or sourcing adapters.
- Broad BS-Series Coverage: — Verified for BS50-2, BS50-2i, BS60-2, BS60-2i, BS65-V, BS70-2, BS70-2i (including EU variants), plus MS52 and MS62 rammers — one part number spans a wide fleet.
- Vibration-Resistant Locking Design: — A lock nut is specifically engineered to resist self-loosening; using the correct OEM piece maintains the integrity of the fastened joint through continuous impact cycles.
- Critical Fastener Safety: — On vibratory rammers, loose or incorrect fasteners can lead to component separation during operation. Using the specified OEM lock nut supports safe, controlled machine use on the trench or compaction site.
A lock nut is a specialized fastener designed to resist loosening caused by vibration, shock, and repeated loading. On a vibratory rammer like the BS-series, internal components generate continuous percussive forces that will work a standard nut loose over time; the lock nut's locking mechanism — whether a nylon insert, prevailing-torque design, or serrated flange — maintains clamping load even under those conditions. When a lock nut fails, strips, or goes missing, the fastened joint loses its holding force, which can lead to component movement, accelerated wear on surrounding parts, or mechanical failure during compaction work.
