The Wacker Neuson Lock Washer A12 Ext. Star is a genuine OEM component designed for the G70, G100, G120, G130, and G150 series portable and mobile generators. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional standards of the original hardware used on the production line. It fits an extensive range of G-series generator configurations including Standard, Cold Weather, Custom, and Tier 4 variants across multiple model numbers. Confirming your generator's model and serial number against the fitment list ensures a straightforward, accurate replacement.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to Wacker Neuson's original material hardness and tooth-engagement specifications, so the locking function performs exactly as designed rather than approximated.
- External Star Profile for Positive Locking — The serrated external star teeth bite into mating surfaces on installation, resisting vibration-induced loosening that is common in generator and power equipment applications.
- Direct Drop-In Replacement — Matches the A12 size specification of the original fastener stack, seating correctly without filing, shimming, or adapting surrounding hardware.
- Broad G-Series Fitment — Compatible across G70, G100, G120, G130, and G150 generator families, covering Standard, Cold Weather, Custom, Tier 3, and Tier 4i configurations in both mobile and skid-mounted formats.
- Protects Critical Fastener Clamp Load — A worn or missing lock washer allows fasteners to back off under engine vibration, which can lead to loose assemblies, misalignment, or accelerated wear on adjacent components.
A lock washer is a hardened fastener component placed beneath a nut or bolt head to prevent the fastener from loosening due to vibration or dynamic loads. In generator applications, constant engine vibration creates conditions where standard fasteners can gradually back out, reducing clamping force on covers, brackets, and electrical connection points. The external star design of the 5000179741 bites into both the fastener and the mating surface when torqued, maintaining tension over extended operating hours and helping keep assemblies secure between service intervals.
