The Wacker Neuson Lock Washer is a genuine OEM component designed for the GV2500A Value Generator and GP2500A portable generator series. As a direct factory replacement, this lock washer delivers the exact dimensional tolerancing and material hardness required to maintain secure fastener tension under the vibration loads typical of generator operation. It is a direct-fit replacement that installs exactly as the original, with no modification needed to mating hardware or fastener assemblies. Verify your model number before ordering to confirm compatibility with your specific machine configuration.
Key Features
- Hardened OEM Material Grade — Manufactured to Wacker Neuson's original hardness and spring-tension specification, ensuring the washer bites and holds under the continuous vibration of generator operation without flattening or backing off.
- Drop-In Fastener Compatibility — Matches the original bore diameter and outer profile exactly, seating flush against the mating fastener and surface without reworking adjacent hardware.
- Confirmed Fitment for GV2500A and GP2500A Series — Validated for GV2500A (60 Hz Value Generator) and GP2500A portable generator models, covering multiple machine configurations within those families.
- Vibration Resistance Where It Counts — A lock washer in a generator application must resist constant engine vibration; a worn or flattened washer allows fasteners to loosen, which can lead to misalignment, rattling, or component failure in the assembly it secures.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000171811 carries the same quality assurance as every component that ships in a new machine.
A lock washer is a small but critical fastening component placed beneath a nut or bolt head to prevent the fastener from loosening due to vibration, thermal cycling, or dynamic loading. In a portable generator, where the engine produces continuous vibration throughout operation, lock washers are essential to keeping covers, brackets, and internal assemblies securely torqued. When a lock washer wears flat or fails, the fastener it supports can back out over time, leading to loose components, unwanted movement, or damage to surrounding parts.
