Clock Pendulum PartsUsually there are three components to a clock pendulum assembly. The pendulum, leader and suspension spring, the suspension is what breaks usually. The suspension spring is the very top part that wig wags back and forth and the leader is attached to it.
The leader is the part that hangs on the suspension, and the pendulum hangs on the bottom of the leader. Getting the proper replacement part is not always simple to figure out, if you have the old parts it is much easier to match up.
Replacing Lost Pendulum PartsIf the parts are lost then its some what tricky, you would need to review the products and instructions below to figure out the proper pendulum part. If you are unable to determine the correct part from below, then you may want to email us the movement numbers off of the back plate and email a picture if able to. The email address is [email protected] and we can let you know what unit is best.
Suspension SpringsUsually there are three components to a clock pendulum assembly. The pendulum, leader and suspension spring. NOTE: Suspensions do not have to be exact in length, if the clock runs slow then raise the pendulum bob with the screw at the bottom of the pendulum rating nut threads. If the clock is running fast then turn the nut as too lower the pendulum bob. The suspensions in the picture are not actual size, you will need to measure your broken suspension spring the best you can and select the closest size in the drop down list by the order button below.

LeadersIf the old leader is lost, the length of the leader needs to be determined. To determine the length on a German movement, look at the CM number off the back plate of the movement. This measurement is the approximate length from the top of the movement to the bottom of the pendulum. So if you measure the pendulum tip to tip in inches and then add an inch for the suspension spring, the multiply times 2.54 it will give you the CM length of all but the leader. The remaining length from this measurement and the CM length from the back plate, will be the approximate leader length.

Top HooksThese top hooks are all for a wood stick style pendulum except the letter "I" and "J" units. Some of the wood sticks come in either 1/2 inch or 1 inch width. The top hook is, in most cases, installed by bending the tabs over as a friction fit. Note: The pendulum assembly consists of the suspension spring on the top, then comes the leader, then comes the pendulum with its top hook attached.
$10.00 – $15.00
Pendulum BobA pendulum bob is the round disk at the bottom of the pendulum and the diameter is the measurement from one side to the other. To select the proper bob size you would need to know the inside width of the clock case. You should have at least 2 inches on each side of the pendulum bob so it can swing in the case without hitting the sides.
$20.00 – $40.00
Long SuspensionsStyle A and B are for antique tall case clock movements. Suspension C is the most popular as it covers many antique and antique replica wall and mantle clock movements. Please note style C comes as a three pack as they have to be cut and bent to fit, and so we provide three units to get it the perfect shape and length.
