I just bought a Howard Miller clock, used but in great shape. It has the Kieninger KRSU movement. It chimes correctly but at the hour it gives only one gong, regardless of the actual time. Is this correct?
Not correct. Take off the hands and see if it works fine. If not take off the dial and the hands both and see if its fine. If not please send a pic of the front of the movement without these things on

I’m repairing a Kienenger 83K 100cm movement. While oiling I noticed that the clutch and verge has been bent and the pin that goes through the pendulum is broken off. Are these parts available?

I have a Ridegeway grandfather clock with curio, Here are the info.gathered from it. M61-853B2K, MODEL 9252, dial It, movement CCK, Serial 99021314, need weights regulator cable.
Hi,
What are the numbers off of the back plate of the clock movement itself? If it is hard to get to, usually you can stick a cell phone up behind the movement and get a picture of the numbers. Or through the side access panel if there is one.

Nice, thank you for the help.
I have a grandfather clock with a kieninger ksu movement and it wont stop chiming the hour. I have been told a stop pin has probably been sheared off. I cannot find any diagram of the part to be replaced. Any help please and its location in the movement
