The Wacker Neuson is a genuine OEM Lock Washer designed for the G50, G70, G100, G120, G130, and G150 series mobile and skid-mounted generators. Sourced directly from Wacker Neuson, this part meets the same exacting standards as the component originally installed at the factory. It serves as a direct-fit replacement across a wide range of Tier 3, Tier 4F, and Tier 4i generator configurations, including switchable 600V and custom URI HVAC variants. If you need to restore a fastened joint to proper clamping force, this is the correct part for the job.
Key Features
- Genuine OEM Hardness and Temper — Manufactured to Wacker Neuson's material specification, ensuring the washer bites and holds under the correct torque load without flattening prematurely.
- Drop-In Replacement — Matches the original dimensions and thread clearance exactly, so it seats and locks without any rework to surrounding hardware.
- Broad Generator Series Coverage — Fits G50, G70, G100, G120, G130, and G150 models spanning Tier 3, Tier 4F, and Tier 4i emissions configurations, including skid base and custom mobile variants.
- Maintains Fastener Integrity — A properly functioning lock washer prevents fasteners from backing out under vibration — a constant stress in generator applications. A missing or worn washer risks joint loosening and component damage over time.
- Verified Part Number — Part number 5100034597 is confirmed against Wacker Neuson's parts documentation for the listed generator models, giving you confidence you're ordering the right component.
A lock washer is a small but critical hardware component placed beneath a nut or bolt head to resist loosening caused by vibration, rotation, and thermal cycling. In generator sets — which run under continuous load and sustained mechanical vibration — fasteners without proper locking hardware can gradually back out, leading to loose connections, misaligned components, or structural failures. Replacing a worn, flattened, or missing lock washer restores the clamping reliability of the joint and protects the integrity of the assembly it secures.
