I recently overhauled this cuckoo clock. The movement was very dirty and someone had damaged the fan fly and enlarged its pivot holes to about 1/8 inch! The slideshow below shows the repair process.
I had to plug the enlarged pivot hole, use the depthing tool to establish the correct center distance, and drill a new hole. Also, the fan fly had been damaged and a brass strip needed to be attached so that the fly fit properly on the arbor.
