    Default Cuckoo music no start or sometimes slow start-stops just fine

    Novice member with thanks for any suggestions:

    Problem:
    Either: music tries to start and music man door stays open
    Or: no music launch at all unless I give the slightest tug on the weight. Then the music starts slowly and it plays a nicely paced tune. Rarely it plays on its own.

    I have a Cuckoo Henry Coehler 1 day movement, with large music fan that sticks up like sails. No other stamps on back plate except : no jewels, made in Germany.

    Time and cuckoo work great!

    Music is one song- Harry Lime tune, and it seems to want to play on 1/2 hr and hour.
    Weights are 429 gm, 412gm, 412gm. The heaviest is one the music chain.

    I have like tried heavier weight, up to 80gms more. It does seem to trigger start a little better but not all the time; it worries me that this is a bandaid..

    I have read the forums on music box adjustments but I have a hard time seeing where the warning is on the music. I have not taken this out yet.

    I will post pictures. Thanks for any ideas.

    Hello.

    The cuckooing and music are interdependent. So if one fails they both do. The music box is often the culprit.

    I see it looks like a different arrangement and yours has the governor section built in the movement. But this might give you some idea.

    One thing about the music box is to not do what I think (trying to recall) a dry run. Where you roll the barrel without the governor. It screws up the tines I believe.

    Thank you you for your quick reply. I have added a short video, showing it needs a slight pull of weight to continue playing.
    Can I make any adjustment without taking it out?

    Hopeful!

    Have you tried oiling it yet? On the oil use a light weight oil and pour a few drops in milk jug lid. Take a small screwdriver tip and touch spots of anything that turns 360 degrees more than once. I would concentrate on the music box portion examining it's train of gears that push it.

    Get the oil right into where the pivots go through the plates or other devices. I would also oil the worm gear at the top. Your not suppose to oil heavily as oil eventually attracts dirt and then the dirt acts as abrasive to ruin the pivots.

    Yes, first thing I did was oil using the special synthetic oil purchased from clock specialist. With tiny tiny drops,I covered all the pivots from the back, worm. I tried to reach in the side and oil toward the front.
    I also hoped that would release the hang up... Could this clock use more weight? Would adjusting the fan sails cause less drag and make it easier to start off? ( I read to adjust the large fans is to loosen screws and move them so they each mirror the other)
    Thank you. I will add some in the music box area, gears etc.
    It looks like the bright silver wire running horizontally starts the music after the cuckoos.
    Another note: sometimes when it works on its own, it would start playing on the hour before the cuckoo is finished calling. However, since this tune runs fairly long it is not a real draw back.

    I'm not sure from the pics, but on most cuckoos you can see much of the front of the movement if you remove the hands then the dial. Usually held on by tiny nails and hopefully not glue. You can carefully prize the dial off and check out the action and study it to look for clues as to why the music is going off too early. Also you can do a better job oiling. This assumes your not ready to tackle taking the clock all apart.

    It looks like the door might be the issue. Unhook it, leave it open and see if that helps. If it does, you might have to look at the hinges, etc. to find the bind.
    A man with a clock always knows the time. A man with two clocks is never sure.

    Oh such a neat idea! I will certainly try that.
    Currently away all day with grand kids.
    I will report back tomorrow.

    I have had the clock since mid winter. It was playing pretty well, then change in temperature to 55 degree in the place it was hanging. May have been part of the issue. Also wondering if the cool temp caused any old oil to gum up.

    Can't wait to try the door.

    Thanks

    Did you oil the music fly and pin barrel? Sounds to me like it's not jumping up to run when it's released.
    The fan sails govern the cuckoo, not the music. You say the cuckoo runs fine, so the problem is at the music box.
    When the cuckoo ends, a wire pulls away a lever that was blocking the fan on the music box, allowing it to run.
    Apparently, it ain't doing it.

    With a count wheel, the pull wire is probably connected to the count lever, so when it falls into a notch, the wire is pulled. If it's starting early, the pull wire needs adjusted.

    Is what I think.

    By the way, welcome to the Message Board!

    I am very hopeful with these good suggestions for better oiling to fan fly, pin barrel and look for hang ups with door.
    I will try these tonight.

    ps Is pin barrel same as worm...?
    since the music gears are so hidden in this movement I am hopeful to find the hang up from your experienced troubleshooting suggestions.
    As another member said he likes to tinker, take things apart, put back together- well so do I.
    However, hopefully it really"ain't broke", so major fixing is not required.

    Pin barrel has little pins that plunk the music box tines (fingers of the comb) to make the music. Yours is a bit different than the average cuckoo, it is more valuable and worth paying for service.

    I have just discovered (on an 8-day cuckoo) that the bird's door hinges can benefit from the tiniest drop of oil. Door now closes nicely.
    Perhaps that might help your situation.

    Pixelating! The shy music man, does not like to be disturbed. Or, he is just busy at work and prefers not to stop what he is doing to play his zither...hmm

    Great suggestions all around. And thanks for your time.

    what have I done so far...
    compressed air to shift any dust etc...okay I really found a tiny beige dried up spider! I'm not kidding. LOL...msg is probably clean the movement!

    foucued on music progression: oiled the music pin barrel axis, other music related gear axis. Learning more about what wire is doing what.

    unlatched the door no difference)

    okay now with more weight, plays without my prompt on the 1/2 hr!
    https://youtu.be/akicNLL2gaY

    Haha - great sense of humor...okay..429gm to 650 gm

    Is it okay to add more weight for the movement?

    Alternatively, I can just let it sit without playing music, for now, until I find a competent repair person.

    Thanks again all!

    You may also try loosening the screws that hold the music box on the side of the case. (take the weight off first) Sometimes the meshing of the gears gets a little tight preventing the music box from taking off. Also if it not working properly off the 429gm weight, then there is an adjustment problem. And, I think the thumbscrew at the bottom of the fly is an adjustment for the meshing of the worm screw which may be binding. All sorts of little problems that can contribute to a non working music box.

    You might try taking the music box completely out first, and see if the movement runs normally without it, since the music box is powered by the gear mesh from the movement.
