The Wacker Neuson is a genuine OEM Lock Washer 5/16 designed for the G120, G125, G160, and MGT3S series mobile generators. As a direct OEM replacement, the is manufactured to the exact material and dimensional standards of the original hardware, ensuring proper clamp load and secure fastening in every application. This lock washer fits across the full G-series portable generator lineup, including skid-mounted, cold weather, and custom configurations, as well as the MGT3S Mobile Generator Dual Axle Trailer with Surge Brakes.
Key Features
- OEM-Grade Hardness and Temper — Manufactured to the same material spec as the original, maintaining the correct spring tension needed to resist fastener back-off under vibration.
- Direct Hardware Replacement — Matches the original 5/16 bore and outer profile exactly, seating flush against mating fasteners without rework or shimming.
- Broad G-Series Compatibility — Confirmed fitment across G120, G125, and G160 mobile generator variants, including skid-mounted, cold weather, and custom configurations, plus the MGT3S trailer-mounted generator.
- Vibration Resistance — Lock washers in generator applications bear constant engine vibration; a worn or fatigued washer allows fasteners to loosen progressively, risking component shifting or electrical connection failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so the part number, material grade, and fitment are verified against the original engineering documentation.
A lock washer works by exerting spring tension between a fastener head and the mating surface, creating friction that resists loosening caused by vibration and thermal cycling. In mobile generator applications, where engine vibration is continuous during operation, maintaining proper fastener torque is critical to keeping assemblies secure and electrical connections stable. When a lock washer fatigues, flattens, or corrodes, it loses that clamping force — allowing bolts to back out gradually and introducing movement that can damage surrounding components.
