How to Reattach a Pendulum on a Grandfather Clock

Have you ever wondered how to reattach a pendulum on a grandfather clock? This article will show you step by step how to do it. The process is not difficult and can be done in just minutes! Let’s get started! First, remove the pendulum from the clock movement. Use pliers for this part. Next, use needle-nose pliers or long nose pliers for this next step.

How to Reattach a Pendulum on a Grandfather Clock

Take the wire that is connected at both ends of the pendulum and pull one end up until it reaches about 1/4 inch above its previous position while pushing down on the other side with your hand, allowing for enough space to insert two fingers. Once you can put one finger on each side of it, get your needle-nose pliers and stretch the wire so that there is enough slack to wrap it around a pencil. Read on to know more!

8 Benefits of Reattaching a Pendulum on a Grandfather Clock:

1. Increased Accuracy:

Once the pendulum is reconnected to the grandfather clock, it will be in sync with its internal timekeeping mechanism. This will cause the clock to start ticking more accurately. If your grandfather clock has stopped running, this might be the only solution. However, if it’s not a problem with its internal workings, you can always use the pendulum for decorative purposes or remove it completely and hang something else from the rod in its place.

2. Balance Wheel Movement:

The clock’s pendulum is what keeps it accurate. As the pendulum swings, it pulls the clock in one direction because of the magnetism in the pendulum and the weights.

3. Reduced Stress:

When removing or opening a grandfather clock, one must be careful not to damage the delicate mechanisms. The pendulum is an important part of the clock and must be removed from the case carefully to avoid damage.

4. The Clock Keeps Accurate Time:

The accuracy of the time is essential for people who make appointments or run businesses based on time. Having an accurate clock can help avoid missed meetings and ensure that deadlines are met. Clocks that are off can cause you to run late for an appointment, but they can also cause a lot of tension and stress.

Having an accurate clock can help avoid missed meetings and ensure that deadlines are met.

5. Clock Keeps its Original Integrity:

Detaching the pendulum is usually done during servicing or if it ceases to function. If this occurs, it can damage or change the features of an antique clock. Reattaching it will ensure that everything remains in its original condition, including any recent repairs.

6. Conserves Original Parts:

If your clock starts giving you trouble, taking the pendulum off for repair will help ensure that any original components stay in their current condition. If you don’t do this, you may need to replace parts or even restore the grandfather clock completely. Even if it’s not a problem, taking the pendulum off and checking it annually will help keep the clock in good condition and ensure that it can be used for many years to come.

7. Maintaining Value:

If you want to sell your grandfather clock for a lot of money, you should try to restore it to its original state. This will make it look nicer and more valuable to collectors. But it might be hard to do and might cost more money than just selling it as is.

8. Easy Clock Storage:

Pendulums are the key to keeping grandfather clocks running smoothly and preventing damage while in storage. By attaching the pendulum to the clock, it becomes much more manageable and can avoid any potential mishaps.

What Tools You’ll Need?

Tools you’ll need to reattach a pendulum on a grandfather clock include:

  • Phillips head screwdriver (preferably the size for clock repair)
  • Small pliers or tweezers
  • Clock oil
  • A small container for clock oil
  • Needle nose pliers
  • Spring bar tool (found at clock or jewelry supply stores)

Instructions: How to Reattach a Pendulum on a Grandfather Clock 

Step 1:

To fix your grandfather clock, you need to take out the weights on top of it. The pendulum should come right off, but if it doesn’t, you can remove the glass and take off the pendulum by removing the screws that hold the weights in place and taking out the weights.

Step 2:

Attach a new weight to your grandfather clock and put up your pendulum. Most grandfather clocks have an adjustment screw for this purpose on each side of the clock. You can tighten or loosen it to make the pendulum swing at the speed you want. If your clock does not have adjustment screws, look inside the case to see if there is a nut that you can adjust.

Step 3:

Remove all of your old oil, if necessary. If your grandfather clock needs new oil (which is unlikely), use a small container to hold the clock oil and drip it very slowly onto each gear while turning them until they are all well lubricated. This is best done with the weights up so you can turn the gears while you oil them.

Step 4:

Rehang your grandfather clock pendulum and check to make sure it’s running smoothly. If not, go through the above steps again until it does run smoothly. Make sure you don’t over-tighten any of the screws, or else the pendulum will be too hard to swing, and it won’t run smoothly.

Step 5: 

Hang your weights back up on the pendulum. Make sure your grandfather clock runs for about eight hours as a test to ensure everything is working correctly.

Grandfather Clock Repair Tips

1. Be careful when you lift the weights off not to pull any of the gears out of line. If you do, they will not be easy to put back. And if you lose one, it is nearly impossible to find a replacement.

2. When you take the weights off, do not knock them together as this could knock out some of the bypasses on the bottom plate, which keep the pendulum going and keep the clock from stopping when it runs down.

3. If the pendulum is broken when you take the clock down, be very careful when you lift it off not to break any of the pieces off in the works.

If the pendulum is broken when you take the clock down, be very careful when you lift it off not to break any of the pieces off in the works.

4. Always handle with care when repairing a grandfather clock. Things are out of alignment, and parts are pressed or stressed beyond their normal working range.

5. It is best not to lift the weights too high off the floor, so you do not stress the clock’s suspension spring system. Also, if you have a pendulum-type regulator, it will be hard to get your first set point needed for the clock to run.

6. When you get the weights off, keep them together because if one of them is lighter than the other, that weight will run faster and may knock over something when it gets going.

Frequently Asked Questions

What Does a Pendulum Hang From?

A pendulum is a weight that swings back and forth in an arc. It is used to measure the force of gravity and to determine the direction of a magnetic field.

Why Does the Pendulum Stop Swinging on My Grandfather Clock?

The pendulum on a grandfather clock typically swings back and forth because it is weighted with lead. Over time, the lead will start to wear down, and the pendulum will no longer swing as freely. This can be fixed by having the clock serviced by a professional.

What Stops a Pendulum From Swinging?

There are a few things that can stop a pendulum from swinging. One of the most common things that stop a pendulum from swinging is gravity. Gravity causes objects to move towards the center of the Earth, and this is why a pendulum will eventually stop swinging if it is not held in place.

Another thing that can stop a pendulum from swinging is friction. Friction occurs when two surfaces come into contact with each other and cause them to resist each other. This resistance creates an energy that can be used to move an object or cause it to change its direction.

Does a Pendulum Ever Stop?

It depends on the pendulum’s condition and how you are using it. If you are using a pendulum to determine the direction of a future event, then it is possible that the pendulum will stop swinging once the event has occurred.

Will a Pendulum Swing Forever in a Vacuum?

It depends on a number of factors, including the size and shape of the pendulum, the atmospheric pressure, and how much friction is present. In general, however, a pendulum will swing for a limited amount of time before it comes to a stop.


The pendulum is an essential part of the clock because it regulates the movement of the hands. Without a pendulum, there would be no way to keep time or handle that all-important ticking sound. So if you’ve lost your grandfather’s beautiful antique clock and are looking for help reattaching the pendulum, this article on how to reattach a pendulum on a grandfather clock should give you some valuable information about doing so.

The pendulum should be reattached to the weight and then placed back on its rod. That’s all there is to it! This article has provided a step-by-step walkthrough of how to reattach a pendulum onto your grandfather clock successfully.
