Kieninger Clock Lyre Pendulum

You need the CM number off of the clock movement itself to get the right pendulum. This information is not on the paper work and not on the wood case, it is only on the back of the movement.

Please view these information tabs to help with determining the proper Mechanical Clock Pendulums for your clock.

Sequential steps to obtain a pendulum

  • 1. First, know who really made the movement. If the clock was made in Germany post WW2, it will be one of four makers. Hermle, Jauch, Kieninger, or Urgos.

    If none of these names are on the movement it is still, most likely made by one of these factories. They made movements for other clock makers who had their own name on the movement because they were buying so many.

    Best to use the identification page to narrow down exactly who made the clock movement. Then return to this page to continue the process of pendulum measuring on German Clocks.

  • 2. Get the CM numbers, or PL numbers from the back plate of the movement itself. Match these numbers with what we are offering.
  • 3. Determine the bob diameter. Measure how wide the inside of the case is and then subtract 4 inches. This will be the maximum pendulum bob diameter that the clock case can handle.
  • 4. Decide between Lyre, Wood stick, or a brass rod pendulum if the options are there. They all come with a brass round bob for the end, but leading down to the bob can be any of these three styles.
  • 5. Order it
  • 6. Once received, the pendulum install it on the clock, then Put The Clock In Beat.

Pendulum Measuring on German Clocks

Measure the pendulum on a German Clock from the very top of the movement down to the very bottom of the pendulum rating nut threads.

Naturally, if the clock says something like 94cm, choose 94cm from the list, making sure it also lists the correct bob diameter. Clockworks will calculate the length, making sure it is correct, before shipping it.

A customer may receive the pendulum and think that it is not the correct length. Most likely, this is not the situation. Ordering a pendulum for a Hermle 94cm movement, does not mean a 94cm long pendulum will arrive. The pendulum may be shorter, although it will be correct.

Determine Bob Diameter after Pendulum Measuring on German Clocks

Of course, bob diameters vary so that they will not hit the sides of the case. bob width is determined by the inside of the case width.

Measure how wide the inside of the clock case is and then subtract 4 inches from that measurement. That measurement is the largest diameter Bob that can be used in the clock case. Likewise, a smaller diameter bob can be used, but not a larger one.

Pendulum clocks need to be put "In Beat"

Finally, after installing the new clock pendulum the clock will need an adjustment for it to run correctly. This is very easy to do and only takes a few minutes. Moreover, no mechanical pendulum clock will run right without "Putting The Clock In Beat" first.

Types of Clock Pendulums

There are three basic categories for types of clock pendulums. These are lyres, wood sticks and brass rods. Mantle clocks have very short pendulums which use a mantle bob. This section will not discuss these types of pendulums. Instead, search the keywords mantle bob if working with a mantle clock.

This will bring up the correct product for mantle clocks. What is in this section is the types of clock pendulums available for shelf, wall and floor clocks. Each of them have their own pros and cons. We can make recommendations on what was typical for a particular clock. Ultimately, it comes down to personal preference.

  • Brass rod style pendulum for small shelf or wall clocks.
  • Metal Lyre style pendulums for floor clocks.
  • Wood stick pendulums are for almost everything.
Types of Clock Pendulums

Metal Lyre

A Metal Lyre pendulum is a type of clock pendulum that is most decorative of pendulums. A floor clock can mean a grandfather, grandmother, or granddaughter clock. Basically, any clock that sits on the floor versus a wall or mantle. These types of clock pendulums are for post WW2 German movements.

This would be Urgos, Kieninger, Jauch and Hermle units.

These are the only post WW2 German units made. Generally speaking, the stamp may have another name on the backplate of the movement. This is due to companies paying a premium to have their name put on the movement. However, this does not change who the actual manufacturer is. In short, the ones who made the movement are one of the German companies already on the above list.

Wood stick style clock pendulum

Wood Stick

The wood stick type of clock pendulum is sent with no stain on it. This is so the stick can have the same stain to match the clock case. Likewise, a black stick looks nice with the gold bob as well. Certainly, by leaving it plain the customer can customize the stick to whatever color they deem fit.

A wood stick type of clock pendulum consists of the stick, the top hook, the rating assembly and the round bob. They are capable of accepting any size bob and can easily be cut if too long. Because of these qualities, they are the most versatile pendulums out of the three.

Types of Clock Pendulums

Brass Rod

Shelf clocks or wall clocks mainly use brass rod types of clock pendulums. It is not common for them to be on granddaughter or grandmother clocks. It is possible but not likely. These pendulums tend to cost more for a couple of reasons.

First, they are made of brass. Of course this is a much more expensive medium than the wood. Second, they are custom cut to size by us here at Clockworks. We will cut it to the exact length needed for the specific clock movement upon ordering. Getting the correct CM length is very important to ensure the brass rod is the right length.

Types of Clock Pendulums In Summary

As shown above, the three styles of pendulums have their own good points and drawbacks. For the most part, wood stick types of clock pendulums tend to be the most versatile. They can have stain, or paint, in any color. Moreover, modifications are fairly easy.

After that, the brass rod would be the next flexible type. They are custom cut to the correct length prior to being sent. Lastly, the lyre pendulum is the most decorative out of the three styles. Modifications to these pendulums are minimal.

Please feel free to contact us if there are any questions on any of these types of clock pendulums. As always, we are here to help. When contacting us, make sure to have the movement number that is on the backplate of the movement itself. This is the only way to know who made the movement. Without this information it is not possible to direct you to which pendulums would be correct. As always, pictures of the movement are always helpful.

Grandfather Clock Pendulum Information

Grandfather clock pendulum information begins with the obvious discussion of length. The length of the pendulum on German units comes in a few CM options.

German units measure the pendulum from the top of the movement to the bottom of the nut threads.

The pendulum itself, the leader it hangs on, and the suspension spring that the leader hangs on.

All three components in centimeters make up that CM length in the drop down menu.

Hermle Clock Movement Availability

Pendulum length information

To know how long the actual pendulum is, subtract 15CM from the options with the pendulum length.

This will exclude the leader and suspension spring, and be the actual pendulum length from tip to tip off of the clock.

This length can vary as if a larger pendulum bob is selected, the actual length of the pendulum gets longer.

Why the CM length matters at all is because if the pendulum length is not near the CM length of the movement, the clock will not keep time.

So the gearing in the movement and the pendulum length works together to keep time around the specified CM length.

The bob width Options

A Lyre grandfather clock pendulum comes with either a 6 1/2, 8 1/2, or 10 1/2 inch bob diameters. The 'Bob' is the round disk at the bottom of the pendulum.

Moreover, the CM length on the movement will indicate the length of the pendulum from the TOP of the movement all the way down to the bottom of the pendulum nut threads.

This is an approximate length that depends on other factors such as bob diameter and weight of the pendulum.

Basically if the CM is 94CM the pendulum itself will be about 35 inches tip to tip off of the clock, and the 114CM option would put this same measurement at approximately 44 inches.

The Mechanical Clock Pendulum Assembly

The mechanical clock pendulum assembly does not mean just the pendulum alone.

The use of the word assembly means the pendulum consists of three components and not just the pendulum. A pendulum assembly consists of the suspension spring at the top, the leader that hangs on it, and then the pendulum.

Pendulum styles

Usually mechanical clock pendulum makers are not movement makers and the two are married together by a person or place. A place such as Clockworks or Howard Miller instead of the movement manufacturer. This is interesting because it explains why there can be so many variations in pendulums for one movement.

The pendulum could be a brass rod, wood stick, or metal lyre style.

Pendulum bob diameter size

To determine the bob diameter for a mechanical clock pendulum, need to consider what looks good as well as which one won't whack the sides of the case. A good rule for the bob diameter is it needs two inches on each side to swing.

So if the clock case is 12 inches wide the bob cannot be more than 10 inches. In this example we would need a 10 inch bob but these are not made.

So the choice is clear that for a 12 inch wide clock case the maximum bob size to get is 8 1/2 inches wide. If this rule did not exist and the 10 inch wide bob is run the clock may go tick, knock, tock, knock, as it hits the sides every time it swings. Eventually the clock will stop running from this resistance. Plus it is quite annoying to hear that sound!

Pendulum lengths for Mechanical Clock Pendulum Assembly

The length of the pendulum has to be correct for the gearing inside the movement. If the mechanical clock pendulum is too long the clock will be too slow. If the pendulum is too short the clock will run too fast. When a clock is too fast or slow it usually has nothing to do with the movement itself. It only has to do with the pendulum length alone and nothing else.

Pendulum top mount hook

The top hook has to hook to the leader on the movement. The leader is the part that holds the mechanical clock pendulum up in the air and it hooks to the suspension spring. Sometimes an old pendulum will not hook to the new movement the same way as it did on the old unit. However, this is not common. It may or may not need a new top hook for the pendulum.

Pendulum leader

The leader is the 3 to 7 inch long part that the mechanical clock pendulum hangs onto. The leader hangs onto the suspension spring which is on top of the movement. At the same time it will have the crutch on the back of the movement engaged with the center of the leader. The crutch is the wig wag part that is sticking out of the back of the movement.

To install the leader, remove the set screw on top of the suspension spring. With the suspension free it can hook onto the leader and be brought back up. The leader then goes onto the suspension and the crutch on the back of the movement at the same time. This assembly gets brought back up again to mount with the set screw like it was.

The mechanical clock pendulum length

A pendulum clock without a pendulum is a shame for sure. Hence, getting the mechanical clock pendulum length correct does take some diving into the clock world.

If there is no idea what pendulum it would take, this is a basic guide. Of course, this is a basic guide to narrow it down to the best pendulum for the clock. This will cover most situations, without special equipment to figure out the length.

The movement CM or PL stamp

On the back plate of the clock movement usually, there are some numbers and or letters for identification. Likewise, there may be an indication of how long the pendulum should be in the mix of these numbers.

It may say CM or PL and this stands for centimeter or pendulum length. Subsequently, this would be the length where it should keep approximate time. Generally, there are a few different ways to measure this depending on the country of origin.

Mechanical Clock Pendulum Length for German made movements

Most mechanical German made clock movements are easy to figure out the pendulum length. In essence, the numbers will let us know or the stamp will clearly state the CM or PL number. If it is German, keep in mind the CM length is not the actual pendulum length.

Altogether, German units measure this length from the top of the clock movement, and this includes the three components of the pendulum all in one length, in centimeters.

This length will include the pendulum itself, the leader that it hooks to, and the suspension spring on the top that the leader hooks on to, all in one CM measurement. To clarify, CM stands for centimeter and PL stands for pendulum length.

If no stamp try to convert

When there is no stamp with the CM on the movement, there are some additional steps that need to happen. You will need to cross reference The numbers on the back plate to the pendulum length that you need. The first step is to identify the manufacturer of the clock movement by using the movement numbers.

The movement numbers indicate who the actually manufacturer is of the movement. Various clock retailers may have a stamp of their name on it, but the numbers are always true to the manufacturer.

Converting numbers to CM length

Moreover, some movements do not have an indication of the pendulum length on the back plate. The unit will have a number that would need to be found on this website first to find out what the correct CM length is for it.

Conversion number example

Generally speaking, let's say that the movement has no CM stamp on the movement and only shows the Urgos number UW32319.

Go to the identification page to look at the movement number examples. In this example, we see that it is a Urgos. Now it is possible to go to the Urgos page and find the number to see what the pendulum length is.

In this example, the pendulum length would be 80cm, representing the full length with the size including the size of the bob.

German grandfather movements

Almost all grandfather clock movements are going to be German if made after 1950. The first thing we need to do is get the numbers off of the back plate of the movement. This is the only way, and we can't cheat by looking at the paperwork or clock case.

It has to come right off the back of the clockworks. The manual and the sticker on the case is of no use to get the pendulum.

American clocks

The American mechanical clock movement manufacturers refer to the pendulum length as a "drop". The drop is the length of the pendulum from the hand shaft all the way down to the bottom of the pendulum rating nut threads.

It is a different way of measuring the pendulum length then the German made way. The basis for both ways are on the smallest bob diameter. If the bob is larger or heavier, the length would be longer than what the stamp indicates.

No luck

If everything fails for one reason or another, the best chance for a pendulum is the wood stick style. This is the only style of pendulum that can be easily modified because it can be cut down.

These types of clocks are usually antiques, or of Asian origin, and information such as pendulum length is simply not available. Sometimes it takes a good guess on where the manufacturer meant to have the bob sit. To do it this way, you only need a pendulum with a stick that is way too long to begin with.

Chop it, try it, chop it, try it. Each time slowly cut an inch and half off of the sticks length and hang it back on. It will only take a couple of times, and if starting way too long it can always go shorter.

Clock makers method for Mechanical Clock Pendulum Lengths

There is another way, which is known as setting the beat rate. This is a more complex way and is usually just done by clock makers. It involves a beat detecting device that counts out the beats per hour, or the beats per minute. To do this, first figure out what the beat rate is suppose to be for that particular movement.

Then keep adjusting the pendulum length until it keeps time. There are cell phone apps out there these days that will tell the beat rate and the cell phone will listen and say if the clock will keep time with that pendulum. Go longer or shorter until the phone says the beat rate is set.

Contacting us for help with Mechanical Clock Pendulum Lengths

Please email the movement numbers from the back plate, and explain what part you need. The email address to send this information to is [email protected]. We always welcome pictures but they are not a necessity. If emailing pictures please include the back side of the clock movement where the markings are.

Timing a mechanical pendulum clock

Timing a mechanical pendulum clock is all about the overall pendulum length. Rarely has anything to do with the movement itself, unless the movement not geared to the proper length from the start.

A mechanical clock is easy to time providing the correct pendulum. When the pendulum is correct for that particular movement it will hang on the leader and keep approximate time.

The fine timing can be done only with the pendulum adjustment located at the very bottom. At the bottom of the bob is some adjustment threads and a nut.

To turn the nut one way raises the bob and the other lowers it. A shorter pendulum will make the clock run faster. A longer pendulum makes the clock run slower.

Fine timing the clock

If the clock is timing slow, raise the pendulum bob by turning the nut at the bottom of the bob. If the clock is fast, do the same but lower the clock's pendulum bob instead. One full turn is somewhere around 1-2 minutes a day faster or slower.

If there is no more adjustment

If the bob is all the way up and its still too slow or fast, shorten either the pendulum or the leader it hangs on to correct.

A lyre pendulum that does not keep time with the bob all the way adjusted will need its length altered. It can be altered with the overall length by the pendulum itself or the leader it hangs onto.

The leader is about 5 to 7 inches long and engages with the crutch on back of the movement. The leader is the part that the pendulum top hook will mount to.

It is possible to shorten or lengthen the pendulum leader to put the clock in time range with some solder if needed. 1 3/4 inches is a good measurement to make one of these longer or shorter as needed, as this is the length of the threads at the bottom of the bob.

So it will give a full timing adjustment range all over again and can go up or down as needed.

German pendulum length CM stamp

The pendulum length is overall and not just the pendulum itself. These German units measure there pendulum lengths from the top of the movement and all the way down. This will include the suspension spring, the leader and also the pendulum itself.

This is based on a 4 1/2 inch bob diameter. Of course the larger the bob, the longer it will be beyond that CM stamp measurement.

Used to keep time, now does not

If the clock kept time in the past but now does not, it means a worn gear. The escape wheel is worn and it is advancing more than one tooth at a time.

The escape wheel alone would be hard to find, and hard to replace both. The entire movement would be disassembled to replace this worn escape wheel if there is another one found that will work.

The cost of having this done would be the same price as a new movement. There is no such thing as having a repair on a clock movement being better than a new movement.

The price would be about the same for a complete overhaul or a brand new one. First see if the clock movement is in production and available new. We do this by getting the numbers off of the back plate of the movement itself, right off of the brass. Please email and we will check the availability and quote for the new one.

If the movement is not in production anymore, then a movement restoration is the only option. You can ship the movement to Clockworks Attn Repair department for a beautiful restoration.

Mechanical Pendulum Clock Timing Issues - Conclusion

Fine timing of the clock is easy as seen. If the clock kept time in the past and now too fast, its time for a new movement and has nothing to do with the pendulum. A worn escape wheel is most likely the cause and a new unit would be less cost then a repair.

Kieninger Clock Lyre Pendulum

The CM number on the movement's back plate (not paperwork or case) is key to finding the right replacement pendulum. For example, it will say a number such as 93CM or 116CM, then a CM (centimeters).

Of note- The pendulum will be much shorter than the CM chosen. However it will be the correct one to keep time. Also, the measurement of German units is from the top of the movement all the way down. It is not just the pendulum.

What is a clock CM number?

The CM number is the pendulum length from the very top of the movement all the way down to the end of the pendulum rating nut threads. This measurement is with the lightest possible pendulum. In addition, this measurement is not only the pendulum itself.

But the pendulum from tip to tip, the leader it hangs on, and also the suspension spring that the leader hangs on. Subsequently, this is a theoretical length. Because the length will vary depending on factors such as the weight of the pendulum and bob diameter.

When a pendulum is lost, just look on the back plate of the movement itself to get the CM length.

What is a clock pendulum bob?

The pendulum bob is the round disk at the bottom of the pendulum. The width of the pendulum bob is important to get correct. Because if the bob is too wide it will bonk the sides of the clock case and the clock will not run. Measure the inside case width where the pendulum is to swing back and forth.

Do this measurement in inches and subtract 4 inches from the total. This will be the largest bob diameter that can run in the clock case. For example if the inside of the case is 13 inches wide, subtract 4 which gives you 9 inches. So the largest bob size that will fit the case is 8 1/2 inches wide.

What is a clock pendulum leader?

The leader is the part of the pendulum assembly that the pendulum hangs on. Another name for the leader is a pendulum hanger. These come in two lengths for Kieninger units. So this will be either 4 1/2 inches long or 7 inches long.

It is important to specify the length of the leader that is currently in the clock. This will enable us to custom make the pendulum to the correct length.

Kieninger clock movement identification

The identification process is the first step to replace a Kieninger clock movement or any other components. To begin with, start with the movement number in order to purchase a new clock movement and to see the price and what it includes.

Also, these numbers are essential to get compatible components for the clock. Examples of some components include pendulums, dials, hands, keys, cranks, chime blocks, mounting screws, weights, pulleys or chains.

Decoding Kieninger clock movements

For example, let's say the movement numbers are 81 K 116cm.

  • 1981 = If it is an on older unit, the 81 would be the year it was made. On new units this number is not the year but only an internal engineering code.
  • K = The K is the movement series. This is the basic raw movement plate size and internal gear configuration.
  • 116CM = This is the pendulum length, in centimeters, from the top of the movement all the way down to the bottom of the rating nut. This is true only for the smallest 4 1/2 inch bob diameter.

Kieninger Clock Movement Identification

Dating the Kieninger movement

In the above description, 81 is the date, however this is not always true in later years. After a certain date that first number is no longer the date that it was made. Rather that first number became an engineering code that has nothing to do with the date.

So it may or may not be the date code, ignore this as it is not pertinent to replacing the unit. There is no longer a solid way to date the Kieninger clock movement unless there is a stamp on the back plate.

We can help

The new movement will fit into the clock case just as the old one did. Keep using the same components such as the dial, pendulum, chime block and weights.

If it is a weight driven clock it will come with the chime hammers as well as chains or cables. If this decoding process is confusing, just email the numbers or a picture to us. We are happy to help with figuring out the best course of action. Similarly, Kieninger clock movement questions and ordering can be done by phone as well.

I need a 116cm pendulum for a Howard Miller with a KSU 33 movement. It has a 1.5″ bob and a 7″ leader. I have an existing pendulum, but my clock repair person said it is damaged. The issues is, our clock has a mirrored back so the pendulum needs to be brass on the front and back, as both are visible. Can you help?

James, My son, John (Matt) Schade is also working this with you folks – we gave him the clock. He sent a note yesterday providing the numbers from the back of the movement. The nbr is UW66004I followed by -01 and some other characters we can’t read. Which we think is a Urgos brand which I think you can match up with an aftermarket pendulum. I will stand down until I hear from my son. I think we are closing in on a solution.

Do the Kieninger lyre pendulums have a bright brass finish. I would assume so, but it does not look like it in the photos to me. I need the 100cm 10 1/2 bob in a bright finish.

Hi, I am looking for a pendulum for a Sligh wall clock – clock movement is Kieninger K with 116 cm pendulum length. Sligh documentation says the pendulum length is measured from the HAND SHAFT which would require a 41 inch pendulum from hook to adjustment nut. Reading on this website says the 116 cm would be measured from the TOP of the MOVEMENT giving a 38 – 39 inch pendulum length. Any information on which is correct and thank you!
