What are some common parts needed to repair a cuckoo clock?

Some common parts necessary for repairing a cuckoo clock include the pendulum, chain and gears, all of which have vital functions in the clock's motion mechanisms. The surface of the clock may also be repaired to create a more uniform appearance.

To determine what sections of the clock need to be repaired, users must perform a simple troubleshooting checklist to narrow down potential issues. The pendulum may need to be replaced if the clock is going too slow or too fast. Sometimes the gears and chains need oiling if the clock stops randomly or if there are strange noises inside the device.
