This was work in progress before I tidied everything up.

These are the component parts
the original screw from speedo drive, two pieces of hard rubber spacer tube and a piece of plastic as a bridge.


One of the spacers has a step cut into it. It fits tight inside the drive hole and the larger bit covers the hole (if that makes sense) The hole in the middle is slightly larger than the drive spigot.



Fitted together prior to going on the bike.


Fitted in place, a bit of threadlock and it aint going anywhere. Keeps all the dirt out and the workings can still spin happily away inside.



Put this one on so you can see the replacement bolt in place on the disc, nice and tidy and it wont ever drop off.


Hope this helps, pictures arnt very good but you get the idea, looks better in the flesh.
Good luck
Chris
