Wacker Neuson 5000103211 Lockwasher

The Wacker Neuson 5000103211 is a genuine OEM Lockwasher designed for the BS50-2, BS60-2, BS70-2, and BS70-2i vibratory rammer series, as well as the BH 22, BH 23, BH 24, BH 40, BH 55, and BH 65 gasoline breaker families. As a genuine OEM component, this Lockwasher is manufactured to the same specifications as the original part installed at the factory, ensuring a correct, secure installation every time. Fitment spans a wide range of BS-series rammer configurations — including standard, oil-injected, variable speed, and high-altitude variants — along with legacy BS500, BS600, and BS700 models. Whether you are servicing a jobsite rammer or a gasoline-powered breaker, part number 5000103211 is the correct OEM replacement to keep fastened assemblies secure and properly torqued.

Key Features

• OEM-Spec Hardness and Geometry — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, so the locking teeth grip and hold under the high-vibration loads typical of rammer and breaker operation.
• Drop-In Installation — Matches the original washer's bore diameter, outer diameter, and tooth profile exactly, seating against mating fasteners without any modification to hardware or mounting surfaces.
• Broad Rammer Family Coverage — Confirmed fit across BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS65-V variable speed, and legacy BS500 / BS600 / BS700 rammer configurations, including standard, oil-injected, EU, and high-altitude variants.
• Breaker Series Compatibility — Also fits BH 22, BH 23, BH 24, BH 24 Low Vib, BH 40, BH 55, BH 55rw, and BH 65 gasoline breaker models across multiple tool-holder configurations.
• Vibration Environment Performance — In high-cycle rammer and breaker applications, fasteners are subjected to constant shock loads; a correctly spec'd lockwasher prevents fastener back-out that can lead to loosened assemblies and accelerated wear on surrounding components.

A lockwasher is a hardened washer placed beneath a nut or bolt head to resist loosening caused by vibration and dynamic loads. In vibratory rammers and gasoline breakers — machines that generate intense repetitive impact forces during every operating cycle — fasteners throughout the drive train, crankcase, and housing are constantly at risk of working loose. The locking teeth or serrations on the washer bite into both the fastener bearing surface and the mating component, creating mechanical resistance to rotation. When a lockwasher is worn, deformed, or missing, fasteners can back out progressively, leading to misalignment, component separation, and potential damage to adjacent parts.
