I am on my third Hermle movement and I always have trouble with the chime side getting started or running too slow. Is there a common issue with this that I am not aware of? The hammers, the chime train, all run freely when not connected to the other. The movement has been cleaned and I only saw one bushing that I felt needed replacement. And the springs seem to be fine. Any help is appreciated.
Sounds familiar. I have a Hermle triple chime grandfather clock movement with a hang-up issue. The clock works great but the chimes will run fine for a while (hours/day) then hang up. That is, they will fail to start at the quarter hour. I hear a click but the locking cam does not turn, thus no chimes. I am learning a lot from this course and maybe I will find out what is causing this problem. I am beginning to suspect a bent pin or something like that. Any ideas?
