This 3/8-inch medium lock washer (Wacker Neuson part 5000025649) is a fastener retention hardware piece used across multiple assembly locations including engine mounts, gearboxes, axle assemblies, clutch and belt guard assemblies, crosshead assemblies, and generator front and frame assemblies. Its split-ring design bites into mating surfaces under torque to resist loosening from vibration, a property that makes it well suited to the high-vibration environments found in portable generators, mobile generators, vibratory plates, ride-on trowels, trash pumps, diaphragm pumps, light towers, and truss screeds.
This washer appears in parts catalogs spanning a wide range of Wacker Neuson equipment families, including the Ersatzteilkatalog series, and is used at fastener locations throughout the drivetrain, engine mounting, and electrical generator assemblies. When replacing hardware during scheduled maintenance or after disassembly of engine mounts, gearbox covers, or crosshead pivot boxes, installing a fresh lock washer ensures fasteners hold their specified torque over time.
