Why does the pendulum on my cuckoo clock stop?

One of the most common reasons owners have issues with their coo coo clock stopping is that the mechanical movement of the cuckoo clock is not level. If the heart beat is irregular, adjust the cuckoo clock’s position on the wall until the tick-tock beat of the pendulum sounds even again.

Why does one pendulum stop and the other keeps going?

When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

How do you balance a pendulum clock?

Give the pendulum a slight sideways push to start it swinging. Listen to the tick –tock. The tick and the tock should sound evenly spaced, if so the clock is said to be “in beat” or balanced. If not, the crutch at the back of the movement will need to be bent sideways to either the right or the left.

Why is my pendulum clock losing time?

The adjustment nut is a large nut at the bottom of the pendulum just below the large disk or weight called the bob. The bob will settle lower, making the effective length of the pendulum longer. The clock will run slower. To speed up the clock, tighten the nut (turn it toward your right).

Why does my clock run slow?

Moving a clock from sea level to a higher elevation will affect the speed of the clock. Pendulum too low or too high: The lower the pendulum the slower the clock will run. Many pendulum clocks can be adjusted either by a set screw at the bottom of the pendulum or by an inset screw on the pendulum.

How do you adjust the pendulum on a cuckoo clock?

To set the time, turn the cuckoo clocks long hand clockwise into position, then flick the pendulum to get it moving back and forth. To set the time exactly, remove the pendulum from its hook. The cuckoo clock shop created pendulum leaf to slide up and down. If time is running too fast, slide the pendulum leaf down.
