This is the Large dished Washer that was used on the bottom of all road going SOHC, OHV and SV petrol tanks to hold captive the rubber washer (our Item 0129) that fitted under the frame tank bracket and protected the tank from vibration. The special Norton shouldered tank bolt (our Item 0124) then fed through this lipped washer and rubber, and through the tank mount and lipped washer (our Item 0128), to screw into the thread that was used on almost all Norton petrol tanks from the 1920's through to the late 1950's (although not Featherbed models, which used a different fixing strap)
Four were Fitted per petrol tank - if a normal type road or pre-bolthru racing tank, all of which would use this dished washer in conjunction with the 0124 type of fixing bolt. However, the same washers were all used on the upper 'Top Hat' rubbers on Manx Bolt- thru petrol tanks, and were also used on the 1950 oil tank upper Top Hat rubbers.
Finally, in conjunction with the special lockwired tank bolts (which our item 0124 bolts are - allowing for them to be lockwired for security), they were also used for the under tank to frame mounting of most wrapround racing Oil tanks, pre 1950.
Our dished washers are as per the original Norton dimensions, but CNC manufactured in stainless steel - so are als0 very pretty and durable, they are one of most popular sellers.
Price is per each
