Key Features
- Genuine OEM Hardware Grade — Manufactured to the same hardness and dimensional spec as the original, ensuring proper clamping load without deforming under torque.
- Direct-Fit Replacement — Matches the original bore size and outer diameter, seating correctly in the same position as the part it replaces.
- Broad Fitment Coverage — Confirmed for GPS9700, GPS8500, GS8.5V, and GS9.7V portable generator models as well as RD880V and RD11V double drum vibratory rollers.
- Prevents Fastener Loosening — The locking profile bites into the mating surface to resist vibration-induced back-off, which is critical in high-vibration environments like compaction equipment and generator applications.
- Correct Part for Warranty-Valid Repairs — Using the genuine Wacker Neuson 5000081026 ensures the repair meets OEM standards for authorized service work.
A lock washer is a small but important fastening component placed beneath a nut or bolt head to prevent the fastener from loosening due to vibration or dynamic loads. In equipment like vibratory rollers and portable generators — both of which produce sustained mechanical vibration during operation — hardware that backs off even slightly can lead to misalignment, component damage, or failure of the assembly it secures. Replacing a worn or missing lock washer with the correct OEM part restores the clamping integrity of the joint and helps prevent more significant repairs down the line.
