242  Dual Purpose Radiused Washer

This rather simple Brass Washer has proved to be one of the most useful parts in our catalogue.  It fits behind the Oil Pump and serves as a Thrust Washer to the Diablo shaped Dual Chain Sprocket Assembly replacing the fibre Washer that was originally fitted by Singer.  Because of the radius on the inner edge, this part 'self-centres' over the shoulder of the Chain Tensioner Sprocket shouldered Bolt which is 'blind' when being tightened up.
