Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the original load and deflection specification, ensuring consistent clamping force and vibration resistance at the fastened joint.
- Drop-In Hardware Replacement — Matches the original bore diameter, thickness, and spring rate of the factory-installed washer for straightforward installation without modification.
- Broad GP, GPS, and GV Series Coverage — Fits GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GP4000, GV3800A, GV5600A, and GV6600A generators across EPA, CARB, CSA, standard, and wheel kit configurations.
- Protects Fastener Integrity — A correctly functioning spring washer maintains preload on critical fasteners under engine vibration; a fatigued or missing washer allows fasteners to loosen, which can lead to component misalignment or mechanical failure over time.
- Verified Wacker Neuson Part Number — Part number 5000162483 is the OEM reference for this washer across the supported generator families, giving technicians and parts managers a reliable ordering anchor.
A spring washer is a hardened, curved or wave-form washer placed beneath a fastener to maintain tension across a bolted joint. Under the constant vibration generated by a running engine and alternator, standard flat fasteners can gradually back out; the spring washer counteracts this by applying continuous axial load against the fastener head, keeping the connection secure. When a spring washer loses its temper, deforms, or is missing entirely, fasteners in high-vibration areas can loosen progressively, potentially allowing covers, brackets, or other components to shift and cause secondary damage to the generator.
