    I am working on a Cuckoo Clock MFG cuckoo for my grand daughter. When pulling the chain normally, the ratchet wheels will not move. Putting them under durres, they do not turn freely. When originally put chains on to test the movement, the chains went on but not smoothly.
    Are these ratchet wheels replaceable? Are they repairable? If repairable, how, as I find no info on that
    Looking at Timesavers, appears they only have ratchet wheel for Regula, Hubert Herr and no m
    Name movements. The Hubert Herr wheels look the closest to what I have but ......... the no names look the same as well. Never having replaced them, would rather gain some knowledge before trying anything.
    Any idea,s. Prefer to keep original movement.
    Thanks in advance for the help.
    Chuck

    There aren't any new replacements that I know of. It looks to me like someone hammered on the brass retainer too far. It should only be pushed down far enough to hold the pieces together and give a little tension. If you look at this pic you can see the difference, your spring plate (with the three tabs), is flattened out. You could probably repair them by taking them out and loosening them up.

    Evening Chris.
    Thank you for your help. I did pull back the 3 pronged piece a bit and it did start turning much better. Taking a good look into the works, also noticed the locking pin seemed to be dragging. Gave her a little oil and it turned even better. Almost like new. Put the chains back on and back on the test stand and she is tick tocking well for 15 minutes now.
    Again, thank you. Now I know a little more.
