I'm repairing a Delco radio. The tuning mechanism works off of friction between the tuning shaft and a large metal wheel. I think originally there must have been rubber on the edge of the large metal wheel, and it's gone. There is about a 1/8th inch gap between the little rubber piece on the end of the shaft and the metal wheel.

Any ideas on how I could make this work again? Here are some photos...

   
   
   

I'm thinking I need to glue something on the wheel so there is contact with the shaft, but what? Or perhaps there is a way to adjust the wheel and move it outwards so it contacts the shaft? Anyone ever seen one of these before?
