A new cuckoo clock movement is factory lubricated and tested. It is still in production so the movement will be the same as you have now, but brand new. In other words it’s not some knock off unit that will not last, it is the same movement you have but new. So to think how old the cuckoo clock movement is now, it should last that same amount of time before a service again with the new unit. The movement comes with the chains, the hooks and rings for the chains and the hand hardware. A cuckoo clock movement repair will not last like a new one would, and it more expensive to get repaired than just getting a new one.
With age, the oil that is supposed to be lubricating the cuckoo clock movement, will solidify and become an abrasive rather than a lubricant. This abrasive creates wear that is usually evident within the pivot holes in the cuckoo clock movement’s brass plates. The pivots spin around in the holes in the plates with the dried up oil, and make the holes oblong instead of round. The oblong holes pinch the pivots, and with the dried up oil also, the clock stops functioning. To attempt to repair this or have it repaired is time consuming, frustrating, and costly. This is because the entire movement gets disassembled and cleaned, then the oblong holes made to be round again via a bushing machine.
Cuckoo clock movements are not always easy to identify but here are some suggestions. To begin with most of the cuckoo movements out there are made by Regula. They have made the most movements and this is automatically what your cuckoo clock movement already is. Although the movement may not say the words Regula, and may say something else on the back plate of the movement, it still maybe this company. So you need to look at the back plate of the cuckoo clock movement itself, not off the paperwork or case. If the movement says 25, 34, or 35 on it, anywhere, it is Regula. Just follow the directions below and you can get a new cuckoo movement. If there is no 25, 34, or 35 on the back plate, its best to email a couple pictures of the movement to us at email@example.com
For cuckoo clock movements that are stamped 25, 34, or 35 on the back plate, or have a KW stamped on it. With this information you can now do the rest of the things required to narrow down what movement you need. First of all, is it a two train movement or three? Although the cuckoo clock movement may have three weights, we need to determine if the three weights all go into the movement, or just two into the movement and one weight controls an “outside of the movement” music box. Most of the time, you will have only a two weight movement and if it does play music, an outside music box. So now, if you have a platform with dancers that spin around, this is a different unit also. You will then need to measure the “drop” as described below. Overwhelmed?

Most popular one day weight driven cuckoo clock movement. Comes with chains, hooks and rings. This movement uses two weights at 5/8 LBS (275 Grams) each (not included). The pendulum is the Smaller one day size.
The drop is the measurement from the suspension post (top of the movement) down to the center of the pendulum leaf where the clock keeps approximate time.

Swapping the cuckoo clock movement can be challanging if you have never done one before but these are the basic steps. Take off the hands, unhook the bird off of the door and remove the hooks and rings from the chains, then flip the clock over. Take the back off and undo the bellow wires off of their lifters. This is done by opening the loop that lifts the bellow wires up and down, open the loop with a small flat screwdriver by twisting it so it will open. Next take out the bellows by unscrewing the screw on the outside of the side of the cuckoo clock case. The bellows will now come out and you can take the four screws out that hold the cuckoo clock movement in. When you receive your new cuckoo clock movement the arm that the bird sits on will have to be bent and cut to size then you can take the bird off of the old cuckoo clock movement by loosening the birds set screw and put it on the new unit. Installation is then the reverse of removal.
