Hi Chaps.
I just have a query regarding a Kieninger SK025. The small lever appears to be dropping into the chime stop wheel too early on the 3x4 run. Oddly it doesn’t do this on the 1x4, 2x4 and 4x4 positions!
Can anyone suggest a reason fir this? I have added a video. The problem isn’t actually causing a problem but I don’t see this sort of thing happening on the hermle movements!
I don’t like these movements at all- just come across as cheap and inferior to the original Kieninger!
Thank you as always.

I'm not seeing it visually. Looks OK to me. Maybe I'm not seeing what you are referring to.

Thanks Shutt. It happens on the 3x 4 run ... if you look closely the fork of the front lever drops into the chime stop wheel too early and gets thrown back out , it shouldn’t be falling at all until the 3x4 run is completed ?

I see what you're saying now. Must be something with the auto-sync feature. That would probably round off your stop slot in time.

Found out the problem Shutt.. the small lever where it rests on the chime count wheel (which as mentioned the hook of which was slightly catching the chime stop wheel on the 3 x 4 run), was worn which had allowed the hook to fall a little too far!
I removed the small lever and slightly elongated the worn section that rests on and follows the chime count, by very slightly hammering it out. This lengthened it just enough to prevent the hook catching the chime stop on the 3x 4 run. Also helped with hook clearing chime stop wheel on 4x 4 run. All fixed now :)

Worn section of lever - part that contacts and follows the chime count wheel. Please note that this isn’t the same lever, this is a spare from another SK movement. 90B53D53-9E41-443B-A43A-3EFA3CFE7379.jpeg

Good job! It's good to know that it wasn't a factory error in design.
