The Bonneville Shop offers a variety of washers for your vintage Triumph, Norton and BSA motorcycle. Washer hardware for motorcycles is an essential component used in various parts of the bike. These washers come in different sizes and materials to suit different applications.Specialized Washers
Some washers are designed for specific applications, such as oil drain bolt washers. These may have specific inner and outer diameter requirements to ensure a proper fit and seal. When selecting washers for your motorcycle, it’s important to choose the correct size and material for the specific application to ensure proper fit and function. Search by part number to ensure you’re getting the right washer for your application.
Key Considerations for Replacing Norton, BSA and Triumph Washers
Preventing Damage
Washers protect the underlying metal surfaces from damage when tightening bolts. They help distribute the load evenly and prevent direct metal-to-metal contact that could strip threads or cause surface damage.
Electrical Connectivity
In some cases, specific washers like copper washers provide electrical grounding. For instance, a copper washer on a stator cover can ensure proper electrical connection between engine components. Make sure your Triumph washers are in good order.
Leak Prevention
Crush washers are particularly important for preventing leaks. When used on oil drain plugs, they create a tight seal and help maintain the integrity of critical components like the oil pan with these Triumph washers
