Now it’s time to set the hands to point to the correct time when the clock cuckoo’s. This will sandwich the minute hand between the bushing and its nut. Next is the hand nut which goes onto the hand shaft where the threads are on the tip. Put this on the bushing and the ridges will somewhat lock it into place in the hole of the hand. Now put the minute hand on (the longer of the two hands). Do not worry about having it point to the right time yet, we will do that later. So the more you twist the hour hand and push down at the same time, the tighter it will be on the clock. The tube it goes on tapers although it may not be noticeable. Simply twist and push at the same time as it is only a friction fit. Twist it and pull at the same time and it will come off. ![]() ![]() The hour hand is next and is only a friction fit. If the bushing is stuck in the hand just remove it by prying up and off with a flat screwdriver. In fact it maybe stuck in the hand itself. This bushing may or may not come off with the minute hand. With the minute hand off it will expose a round bushing that has a square hole in it. Now you can turn it with your fingers and it will come right off. Turn the hand nut in a counter clockwise direction while holding the hand still will loosen it up. While holding the minute hand still (longer of the two hands) loosen the minute hand nut with the pliers. To remove the cuckoo hands you will only need a pair of needle nose pliers. Installing the cuckoo clock hands bought from starts with removing the old hands. These spinning gears dictate a lot of action and any resistance in any part will stop it from working. These 4-5 gears need to spin to have the bellows lift and open the cuckoo door at the same time. However, it will not function if there is any resistance. There is only 4 or 5 gears that have to spin around to make the clock cuckoo. Resistance causes the cuckoo to not go into striking mode. Putting a bend in this wire so it has a hump instead of straight will be the same thing as making it shorter. The solution is to make the door wire shorter or put a bend in it. The cuckoo strike cannot start if the bird door is open too much. When this wire is too long, it will try to open the bird door too much. Furthermore, it will only cuckoo if the bird arm is able to be all the way forward with no resistance. ![]() The intent is for it to open the cuckoo door only and not hit the front of the clock case. Therefore it hits the front of the clock case instead of the position where it opens the door. The arm that the bird rests on could be bent in a way where it is trying to go forward too much. When bellow tops are broken or torn it can cause this to happen also. These just get bent this way or that way so they can go up and down with the bellow tops. Because the bellow wires could be hitting each other and creating resistance if they got caught up on each other during the travel. On a new cuckoo clock movement install, you have to bend the lift wires so they do not get caught up on each other. This is the side that you pull to raise the weight on the other side of the chain loop. Also the side of the chain that there is no weight can't be caught up on anything as well. The chain that holds the weight should be straight from the ratchet wheel and down without rubbing anything. It would be equivalent to not having enough weight to make it run. If the chain is rubbing anything, like the hole in the bottom of the cuckoo case, it will not run. One weight controls the time and the other the strike. Clock chain resistanceīe sure nothing is in the way of the chain that drives the striking side of the cuckoo clock. Many manufacturers silence the cuckoo just by locking the bird door. Here is where you may see the silence switch.Īs you are facing the back of the movement, look for a lever on the right side near the top. Simply look at the back of the clock with the back panel off. But it may still be on the movement itself. Sometimes the movement has a silence switch that does not stick outside of the case. Just move it to the opposite direction and see if the clock will strike out the cuckoo calls. Push it down for cuckoo on and up for cuckoo shut off. The silence lever is on the side of the cuckoo clock movement and sticks outside of the clock case. There may be a silence lever if the cuckoo movement has one. Be sure it is out of the way so the door can open and it can cuckoo. Turn this wire either in the way or out of the way of the door. This is for either shipping the clock and also for chime shut off. ![]() Here are some guidelines on what to check in this situation. The bird will not come out and the clock will not indicate what time it is with the cuckoo call. The following is for when the new cuckoo clock movement will not go into striking mode for the hours.
