I am having difficulty finding the right beat on the verge of this cuckoo clock. I would appreciate any suggestions and experiences related to this little movement. Thanks Kelwing2132

I have moved this inquiry to the Clock Repair forum where it should get better exposure.

The clock was cleaned in the ultrasound cleaner, rinsed in alcohol and then oiled. The clock runs for a period of time then it quits. I have listened to the clock and have had a strong even beat then after a few minutes or less, the escapement slows and the clock stops.

Kelwing2132, did you have this movement completely apart when you cleaned it? The description of the problem is not very clear. "Runs for a period of time" :???:? "after a few minutes of less":???:?? We do not know what that means. "finding the right beat":???:? or what that means. There are people on this forum that can help you but more info is needed and pictures are always helpful.

Your problem is indicative of a worn out movement.

Clean/oil are good practices but are preventative rather than curative. It may be you are trouble shooting the problem incorrectly.

Please take time to check the lateral play in all pivot points in the clock movement. The normal solutions are to replace/properly rebuild the movement.

Best Regards,

Dick

I agree with Dick, this usually means the clock will
need some repair. Cuckoo clocks usually have sloppy
bushings to start with. A warn bushing will show as an
oval shaped bushing rather than a round one.
A couple of things to check before giving up.
Check the trapeze to make sure it is positioned
right. Also, make sure it isn't warn flat where it
connects.
Also, make sure none of the pivot are bent. With
not load on the train, you should be able to pick
up the movement and the arbors of the wheels
should slide easily by gravity, slightly from side
to side ( end play ) of about .020 to .050 someplace.
In any case, the reason it is stopping is friction, someplace
or over many places.
If it is because of bushing, it has allowed the mesh
of the pinion and wheel to get too far from the
correct position, causing friction.

If you rock the large wheels back and forth with your thumb while looking at the other pivot holes, you will see one or more moving back and forth in a straight line. Those will be your problem areas where bushings will have to be inserted. You could, of course, replace the movement with a modern Regula 25. They are not expensive.

No the movement was not taken apart on cleaning. I used a solvent cleaner from Perrins as well as an ultrasonic cleaning. It was rinsed with alcohol and blown dry, then lubricated before going back on the stand.
I am in the process of checking the pivots now. Thanks

Old thread, evidently left hanging, but it could have been split into a second thread?? Willie X
