The Wacker Neuson is a genuine OEM Nylon Flat Washer 8.4X24X2.36 designed for the GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A series portable generators. As a direct factory replacement, this washer meets the exact dimensional and material specifications called for in the original equipment build. Sourced directly through the Wacker Neuson parts network, the delivers consistent fit across the wide range of GP and GPS generator variants it supports — including wheel kit, electric start, EPA, CSA, and CAN GFI configurations.
Key Features
- Nylon Construction, Correct Thickness: — Molded from nylon to the precise 8.4 x 24 x 2.36 mm profile, ensuring proper load distribution and isolation at the mounting point without cracking or deforming under generator vibration.
- Genuine OEM Specification: — Manufactured to Wacker Neuson's exact material grade and dimensional tolerances, so the washer seats flush and holds torque specs as designed — no shimming or improvising required.
- Broad GP/GPS Series Fitment: — Confirmed fit across GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A generator families, including EPA, CSA, CAN GFI, wheel kit, and electric start variants.
- Protects Mating Surfaces: — The nylon material prevents metal-to-metal contact at fastener points, guarding against surface wear, galvanic corrosion, and fastener loosening over the generator's service life.
- Drop-In Service Part: — Installs in place of the original washer with no alteration to hardware or surrounding components, making it a straightforward swap during routine maintenance or repair.
A nylon flat washer serves as a load-spreading and surface-protection element positioned beneath a fastener head or between clamped components. In a portable generator, washers like the 5000162291 prevent fastener heads from pulling through or marring softer mounting surfaces, and the nylon material adds a degree of vibration isolation that helps keep hardware tight during operation. When a washer is missing, cracked, or the wrong size, fasteners can work loose over time or damage the surfaces they bear against — leading to misalignment, noise, or more costly hardware failures down the line.
