Key Features
- Genuine OEM Material Spec — Manufactured to Wacker Neuson's exact thickness and hardness tolerances, ensuring proper load distribution and clamping force at every fastened joint.
- Drop-In Replacement — Matches the original bore diameter and outer dimension exactly, seating flush against mating fastener hardware without filing or shimming.
- Broad Generator Family Coverage — Confirmed fitment across the GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GV3800A, GV5600A, GV6600A, GV5000A, GV7000A, and GV7003A series, spanning EPA, CSA, CARB, and 50Hz configurations.
- Protects Mating Surfaces — Distributes fastener load evenly across housing and panel interfaces, preventing surface deformation, loosening, and fretting that occur when washers are missing or worn.
- Verified by Part Number — Cross-referenced directly to Wacker Neuson 5000158488 for confident, accurate ordering across the full GP, GPS, and GV generator lineup.
A plain washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it clamps against. Without a correctly sized washer in place, the fastener can pull through or deform softer housing material, cause vibration-induced loosening, or fail to achieve proper torque, all of which compromise the integrity of the assembled component. On portable generators like the Wacker Neuson GP and GV series, where engine vibration is constant during operation, correctly installed washers throughout the assembly help maintain secure connections across panels, covers, and structural hardware over the life of the machine.
