Bob Thanks for the reply I usally work on 400 day clock so this is new to me. I removed the arbor, the click wheel is still attached to I assume clutch plate on the back side of the large wheel. I come from school of ask first then screw it up so forgive me for asking the dumb stuff, it appears the back side is peened over to engage the plate. I have popped the plate off and pushed the click wheel out of the large wheel. Now all I need to do is find a new one.
