    I have a German coo coo clock. It has music in addition to the coo coo. (1) the door shuts and reopens with each coo coo, so if it’s 10 o’clock, the door opens and shuts 10times. (2) there is a clicking sound when the music plays.

    The gathering pallet needs to be adjusted so it locks out and stays locked. The clicking sound maybe the butterfly hitting the lock out lever. if there is a plastic tube you may have to move it to in gauge the butter fly more. Or the wire that keeps the music from playing till the cuckoo is finished may need to be adjusted.

    It's not the gathering pallet. There's a latch on the right-hand (3 o'clock side) of the movement that's supposed to catch the bird perch rod and keep the bird out and the door open during the strike. It's not doing its job, and needs adjusted. Sometimes there's a window on the side of the clock that lets you see that part of the mechanism.

    Cuckoo's have several very different mechanisms to hold the door open. Some are easier to understand than others but a photo of the front of the movement would be necessary for troubleshooting. I'm guessing you have a
    40 to 50 year old clock there?

    The clicking is usually caused by a craked plastic gear. Look closely at the little shaft that holds the MB fan/fly. It is often driven by a white plastic gear, look closely at that gear and you will probably see a small radial crack.

    Your MB and main cuckoo movement will need to be removed to repair and service it. Not easy, even pros have trouble with cuckoos!
    Good luck, Willie X

    The gathering pallet job is to count the teeth on the rack, not to lock the bird in place, the locking for the bird needs to be adjusted.

    If it is a Schatz cuckoo then the cuckoo door is designed to open and close at every cuckoo. I agree with R&A on the possible clicking sound.

    yep, the plastic gear split, usually on one side. Eventually it will quit. Problem is the cuckoo and music box are all interdependent of other.

    There was a recent post about this kind of repair where one can buy that gear. If you plan to replace the gear yourself keep in mind that you can simply bend the metal with needle nose to make room to pull out the gear. The plastic gear is friction fit so it will slide off.

    Not so. When properly adjusted, the Schatz keeps the door open during the strike. (I learned that from Dave LaBounty).
    See THIS post.

    Okay so what do you do if it's a regula movement We don't even know what movement it is. The cam on the inside of the movement if a Regula needs to be vertical and the locking lever needs to be all the way into the gather pallet so the warning pin locks as soon as it drops into it. If the cam is to high, it will lift and the door will keep opening and shutting every time it goes to lock out. Not allowing the lever to lock out into the gathering pallet. So yes if you adjust the gathering pallet it will change the position of the cam and all will be good.

    I misspoke. The door on a Schatz remains open meanwhile the cuckoo bird goes in and out for each cuckoo. On a Herr and Regula the bird stays out during cuckooing.

    Plus the gathering pallet is on the same arbor that has the cam that has to be vertical when locked out. The cam is on the inside of the movement. When it lifts it will hold the bird out with the door open and when it locks out it disengages and the bird pops back in. If that help on a Regula movement adjustment

    More like 45 degrees, the rocker lever sits on lowest point of the cam that's is between the plates, the cam is on the gathering pallet arbor, when the strike train runs the cam lifts the rocker lever which in turn pulls the vertical lever the bird rides on allowing the bird to move out, the rocker lever is locked by another lever inside the plates.

    The gathering pallet counts off the cuckoo's then lets the rack hook to drop which in turn slaps the locking lever releasing the rocker lever allowing the bird to snap back in.

    This is the way Regula movements work, usually the bird lock works pretty well, problems can happen if the rack hook spring is missing or broken then the cuckoo won't shut off consistently.


    hubert Herr is a bit different, Schatz yes the door is supposed to lock open and the bird moves in and out, but they can be problematic, specially if someone has sprayed something in the clock.

    I'd still prefer a non-nylon part.

    Now that I think of it, I recall filing notch just a touch on one of those locking lever, that cured the problem. Also I recall the cuckoo would not stop as it should before the filing. I remember thinking a delicate balance between no lock or stuck. Pretty sure it was a regula, with that odd looking black plastic smooth wheel thing. Junky was my impression.

    Nylon is good in situations of high wear occurrence but is next to useless when pushed onto a metal shaft.

    It may be possible to close the gap somewhat by various methods but from experience, this often only results in greater failure.

    I believe that at a 45 degree the bird will come out on warning and will lift < I would not want this

    Black Forest Industries (or something like that).

    Later correction: Imports. (You'd think I'd remember.)

    I purchased some of these from Black Forrest Imports, could not find any where else. Common problem is that the nylon or plastic of some sort splits over time and renders the mb useless. Much less money than replacing the mb, the one I priced was $100.00.

    Have another look, I usually set this so the rocker lever is at the lowest point on the internal cam, this is about 30-40degs from the horizontal, when on warning there is no lift of the rocker lever, only when the train starts to run at full speed will the bird be pushed out.

    Was reviewing this thread for something else, and noticed the discussion about plastic gears on the movement. Maybe it would be worth some time when replacing a worn out movement to go ahead and strip it for some of the parts you could use later, like E-clips that go flying away or dropping on the floor, metal gears when they were used, to replace the plastic ones, little springs, wave washers used on movements with dancer tables, etc.? T'would save a lot of trouble, fuss, and money. Just saying..................................gary;)
