How do I speed up the chimes on my grandfather clock?
The clock can be made to go faster or slower by means of the nut at the bottom of the pendulum. Turning the front of the nut to the right speeds up the clock, and turning it to the left slows it down (in other words move the nut up to speed up, or down to slow down).
What do you do when your grandfather clock is slow?
If the clock is running slow, move the bob up or turn the nut to the right. Restart the pendulum and reset the clock hands to the proper time. It is easy to remember: lower is slower and left is lower.
How do you slow down a chiming clock?
To slow down the clock, loosen the adjustment nut (turn it toward your left). 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).

Adjusting the Hourly Chime
- When your mantel clock chimes, count the number of times it chimes.

How do you manually lower weights on a grandfather clock?
Using cloth gloves, or at least a cloth of some kind, pull down on the weight some. This is the same as making the weight weigh more. At the same time, turn the minute hand past the quarter hour to see if it will engage the chime. When you advance the time and make it chime, the weight will slowly come down.
How do I adjust the chime on my pendulum clock?

Where should the weights be on a grandfather clock?
If there is no markings to identify the weights, hang the heaviest weight on the right side as it needs more power to run all of the chime hammers. The other two equal or lighter weights should be placed in any order on the left side and center position. This will usually work on most grandfather clocks.
Why is my grandfather clock running slow?
These factors include heat, cold and humidity. Increasing the ambient temperature of a clock will slow it down from the expansion and lengthening of the pendulum unless the pendulum is a compensating type. Denser air causes the pendulum to move more slowly.
How do I fix the chimes on my grandfather clock?
Repair grandfather clock chimes by adjusting the clockâs minute hand. Stop the pendulum as soon as the grandfather clock begins to chime at the wrong time. Write down the time. Grasp the minute hand with one hand. Use pliers to take hold of the nut on top of the minute hand.
What would cause a grandfather clock to stop working?
This might be caused by the front to back leveling of the grandfather clock. If the back is too high, the pendulum will drag on the weights and stop the clock. If the front is too high, it will drag on the chime rods. Also, check for an even tick tock with the pendulum attached.
