Hi Roger
Quite simple really. Just place the rubbers in the hub so that the bottom edges of each pair of rubbers are propped up against each other so as to form a V where the vanes on the sprocket fit. Align the vanes and push together. Thats it!
You can always apply a little tyre lubricant as used at your local tyre fitters if you want to make it a bit easier.
