The Wacker Neuson 5000012648 is a genuine OEM Lock Washer A12 designed for the BS50-2, BS50-2i, BS52Y, BS62, and BS68 series gasoline vibratory rammers. As a genuine Wacker Neuson part, it is manufactured to the exact dimensions and material specifications required for proper function in these machines. This lock washer is a direct-fit replacement sourced straight from the original equipment manufacturer, making it the correct choice for service and maintenance on BS-series rammers across a wide range of serial number configurations. Confirming your model and serial number against the fitment list ensures you receive the right part the first time.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original hardness and spring-tension specification for a lock washer, ensuring correct clamping force and resistance to loosening under vibration.
- Direct-Fit Installation — Sized to A12 specification for drop-in replacement at the original fastener location with no rework to mating hardware.
- Broad BS-Series Compatibility — Confirmed fitment across BS50-2, BS50-2i, BS52Y, BS62-2, and BS68-2 rammer variants, including Sunbelt-designated configurations.
- Vibration Resistance — A correctly tensioned lock washer maintains fastener preload through the high-cycle impact forces generated by rammer operation, preventing bolt back-out and hardware loosening during use.
- Fastener Safety — On high-vibration equipment such as jumping jacks, a failed or missing lock washer can allow critical fasteners to back out, creating a structural or operational hazard; replacing worn hardware promptly is essential.
A lock washer is a hardened, spring-tensioned washer placed under a nut or bolt head to prevent the fastener from loosening due to vibration or dynamic loading. On vibratory rammers like the BS-series, the machine's rapid impact cycle generates continuous shock loads that work against threaded connections; the lock washer compensates by maintaining tension on the fastener joint between tightening intervals. When a lock washer loses its spring tension, deforms, or is missing entirely, fasteners can back out progressively, leading to loose assemblies, component misalignment, or hardware loss during operation.
