The Wacker Neuson Lock Washer B16 is a genuine OEM Lock Washer B16 designed for a wide range of Wacker Neuson portable generators, trash pumps, vibratory plates, and hydronic surface heaters. As a direct OEM replacement, part is manufactured to the same specifications as the original hardware installed at the factory, ensuring consistent fit and function across the G25, G50, G70, G85, G110, G125, PT6LT, PT6LS, BPS 2550A, VPG165V, VPG165A, VPG170A, HSH 380S, and E1250 series equipment families. Whether you are servicing a skid-mounted mobile generator or performing scheduled maintenance on a trash pump, this lock washer delivers the clamping security and fastener retention the machine depends on. Confirm your model number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the same hardness and dimensional tolerances as the original, so clamping force and thread engagement remain consistent with the machine's design.
- Drop-In Installation — Sized to B16 specification, this washer seats directly onto existing fastener hardware without any modification to the host assembly.
- Broad Fitment Across Multiple Equipment Families — Confirmed for G25, G50, G70, G85, G110, and G125 portable generators; PT6LT and PT6LS trash pumps; BPS 2550A and VPG-series vibratory plates; HSH 380S hydronic heaters; and E1250 series heaters.
- Fastener Security Under Vibration — Lock washers are especially critical on compaction and pump equipment where constant vibration can loosen threaded connections over time; a worn or missing washer risks fastener back-out and component damage.
- Genuine OEM Traceability — Sourced directly through authorized Wacker Neuson parts channels, so part number 5000012650 is fully traceable and consistent with current production specifications.
A lock washer is a hardened fastener component placed between a bolt head or nut and the mating surface to resist loosening caused by vibration, thermal cycling, or dynamic loads. Its spring-like or toothed profile bites into the fastener and the mounting surface, maintaining clamp load even as the machine operates under continuous stress. When a lock washer wears flat, fractures, or goes missing entirely, the fastener it secures can progressively loosen, leading to misaligned components, fluid leaks at sealed connections, or structural failure of the fastened joint — any of which can escalate into a costlier repair if left unaddressed.
