    Hi,
    First I'd like to say that I'm a complete novice at repairing cuckoo clocks.
    Uhm, so I was given this Hubert Herr cuckoo clock to examine and clean for someone.
    But one thing I notice is that the bird door opens 3 times at say 3 o'clock instead of opening once and doing three cuckoo sounds.
    It seems odd and I have no idea if this is normal for this model cuckoo clock or not.

    Any help will be appreciated, thanks.

    It is not normal. These movements have several methods
    to latch the bird out. I don't have a movement like that handy
    so can't tell you how it works on this movement.
    Some have a piece that rotates and some have a bar that drops
    down.
    It is likely the result of in appropriate oiling in the past. There
    are a lot of parts on a cuckoo that should not get oiled.

    That clock looks like it has some age to it. It should be noted that cleaning (and especially intact cleaning) won't do anything to fix the natural wear that has occurred.

    There's a latch that catches the bird perch wire when the bird pops out, and holds it until the cuckoo is finished.
    For some reason, it's not working. Remove the lefthand whistle & bellows, and check that side of the movement. You may be able to spot the problem.

    Follow this wire up to the top, and you should spot the problem.

    Hi,
    Ok thanks. Tinker that was my first concern when I received it - too much oil basically everywhere :)
    I did not use any fancy cleaning stuff, just a diluted rust remover (with sulphuric acid as ingredient) and water combination, left it in there for 15min
    and then cleaned with dishwashing liquid in warm water. Cleaning with a toothbrush and small paintbrush afterwards.

    The latch is dependant on its linkage being pushed past the latching point. Adjustment is done by slightly bending that wire that angles downward, just inside the right side door. The perch latch is released and the bird and door slams shut. This is done when the rack drops completely down after the last count.
    Note, the clean-up you did would be considered a rinse. This should never be done with anything caustic. Reason being, that it is impossible to remove the caustic solution from anything except open surfaces. There are many areas of your clock where the caustic residue, along with some water, is now hiding!
    Next time use a petroleum solvent, like mineral spirits or Coleman lantern fuel. That way the material you leave behind won't cause future problems.

    Confusing and strange that in this photo I took before I started disassembling the clock, the pin is on the other side of the wire?

    Reason for this is to stop the bird functioning?

    Ok I made some more pictures, but I hope it will be of value regarding the problem.

    Anyway I followed the wire to the top and found the locking rod.

    This is the other side of the drop down lock pin.

    The front, I am still examining the movements by turning the sound chain sprocket and turning the minute hand to
    see how things work here.
    View attachment 353428

    These pins on the gear wheel looks slanted to the side.
    Should I straighten them?

    The long wire pointing downward at the right side of the movement (as you face the clock) needs to be bent slightly inward. Enough to make the latch actually latch. The latch catch is that vertically movable bar at the red arrow in your first photo (last post). The latch hook is on the silver lever, inside the plates just bellow the latch bar.

    I have one on the wall, just like that with the bar that
    drops down. The previous own gave me the clock and said
    that it has never worked right, since new.
    I looked at it for some time before I realized that the slot
    was too narrow and that it would never have worked. I
    widened the slot by about .001 inches and it has been
    working fine ever since.
    Mine is an 8 day and they are generally fussier.
    The bar that falls must be clean with no oil or rust.
    Run slowly by hand, now that you have it out.
    The problem should be more easily seen.
    The pins on the wheel should be straight but I don't think
    they are the issue. If you straighten them, you take a
    chance of having them get loose on the wheel.

    Thank you Tinker, your thorough examination paid off, good for you to have noticed that,
    and you got the clock for free? - great!
    Now (with manual hand advance) I can see everything clearly and am satisfied as the bar (well cleaned) falls
    easily into place plus I notice the bird perch stays out for the full count now, only coming back inside after the
    number of cuckoos have sounded.
    And I did not put any oil on that bar :) just major places where various rods slot into the front and back plates.
    I used synthetic oil (actually from my ABU fishing reel) :)
    Those pins I left alone yes, but just cleaned them again (this time) with mineral spirits!

    As a general rule for the future, only rotating parts get oiled.
    Pivots for levers and such should be dry.
    Teeth and pinions stay dry except a tiny amount on the escapement teeth.
    It really has to do with load. No load no oil.
    Oil accumulates dust, no matter what type. Dust can be abrasive
    as well as gumming up the oil.
    If a clock would run well without oil, that would be best.

    Ok, sorry ... stupid me, this is the correct way the pin and shaft should be (other way around) ... :screwball:

    Does that lever retract at the end of the strike? If so, you have a return spring unhooked or broken (lower part of the perch wire assembly).

    Hi,
    It did not at first yes, so I fiddled with angle of the pin (on pedestal ) and also the height of the tail lift wire, and now it does :) ... phew !
    Another question if you don't mind .. about that pin on the pedestal - can it change the amount the door opens, say like less or wider open?
    Sorry, I should have updated the situation as I was watching it for a while now.

    Yes, the length of the door wire effects how far the door opens. However, unless you suspect it's been modified, it's probably the correct length. The bird may not be moving far enough to open the door all the way. Check for the perch being obstructed at the bottom of the door opening.

    Oh ... and I did bend the lever inwards towards the pedestal shaft so that it's exactly parallel with the pedestal shaft (as opposed to in the photo I posted).

    Exactly ... I fixed that a few days ago. It was only a fraction too low and thus touched the bottom of the door.
    I used my US Made (PO) craft knife (previously used for balsa planes etc.) to cut a little off at the bottom as the door still covers it :)

    Yes I think its not the original wire. I looked at some other HH clocks wires and they are definitely not the same.
    Actually the door opens too wide for my liking, and the tail lift wire's shape is a problem in this clock, as it moves the door slightly while the birds sings.

    OK, you can shorten it a bit then. Bend first, cut later :)

    Here is a photo I took when I first got the clock.

    The tail lift wire was way off and touching the opposite bellow !
    So at present I only have a basic idea (just guessing really) of it's shape and angle :(

    Yes I will try, as this wire is thinner as the original it should not be a problem, thanks :)

    One of this clock's previous owners did a lot of changes :(

    One of them is that he glued the sound boxes while there was holes in the sides (made by who-ever :))
    So I managed to loosen the sound boxes, as luckily only a little amount of epoxy was used and I used brass screws instead. :)

    Also the wood is very dry and I have Linseed oil that I used to apply to the unpainted areas :)

    Lots of stuff ... :)

    This is my sister's clock and seeing that it's women's month she will be thrilled when she sees it (they are on safari at the moment up north).

    Here where I am, in the Cape it's been very dry and dam levels are so low (25% - 80%) that unless we get a lot more rain soon
    we are in for a difficult summer season coming. :)

    :) Way off topic, but anyway some background info.:)

    The bird wire should be straight and UNDER the tail. If it won't reach the bird, bend a couple of 90° angles so it isn't slanted upward like that. It doesn't need to be that long either.

    Thank you :coolsign: - I took about 2-3mm off and it worked like a charm! the door is perfectly still
    when the bird is doing the cuckoos :thumb:
