This A16 external star lock washer secures fasteners at the fuel tank and underframe assembly locations across the G150, G180, G230, G240, and G320 mobile generator lines, providing the tooth engagement needed to resist loosening under vibration in generator applications.
The external star profile bites into the mating surface when torqued, maintaining clamp load on fuel tank mounting hardware and subframe connections that are subject to continuous engine and load vibration during operation. Specified as part number 5000178507 in Wacker Neuson's parts catalog, this washer appears across multiple assembly locations including the fuel tank, underframe, subframe, pallet and fuel tank assembly, and associated fuel system components on T4i and Tier 4 Final generator configurations.
Compatible with the following Wacker Neuson models:
Fitment covers standard, cold weather, and custom configurations, as well as Transport Canada certified mobile generator variants in the G230 and G320 families. When replacing fuel tank or subframe hardware, using the correct lock washer specification ensures fastener retention is maintained to the original design standard.
Genuine Wacker Neuson OEM part, sold by an authorized dealer.
