Changing location of gear tooth with gear's overall dimension

See attached. I'm trying to update this part I've inherited and my task is to decrease the gear's overall dimension. The initial diameter was set by using revolve about an axis and then the teeth were created using the cut feature. When I decrease the size of the diameter to say, 15mm, the sketch for the cut doesn't move with it. The sketch has concentric and fixed relationships. Deleting those and trying to re-position the sketch so that the cut goes through the new revolved body doesn't work. I've attempted to add dimensions from the bottom and top of the sketch to the middle of the revolve; changing that doesn't do anything.

 

I can't figure out how to move this sketch if I decrease the diameter of the gear. Can anyone help? I've attached the part. Any help I can get would be great!
