Grandfather Clock Weights Description

The Grandfather Clock Weights Description on this web page will cover what is meant by weights and their parts. Any part of the weight is available on its own. We also offer complete weights. If needing a complete clock weight, we need to determine what the appropriate weight is for the clock. This requires getting the information off of the back plate of the brass movement itself. This information will not be on any of the paperwork or clock case. Once the movement number is known, cross reference that with the weight chart. The other piece of information that you need is the diameter of the bob. The bob is the round disk at the bottom of the pendulum.

The weight chart

Before using the chart, it is needed to know who made the clock movement. This can be deceiving because the movement can have any name on it, but it may not be the true maker. For example, a Hermle unit may have the name Sligh, Ridgeway, Howard Miller and so on. The numbers on the movement is what will lead to getting the correct manufacturer of the movement not the names on the movement. The stamp with these numbers are right on the back plate. Use the movement identification page to find out who made it. Once the manufacturer is known and the starting numbers of the movement, use the chart to see the weight specifications for the Grandfather clock weights.

Avoiding the weight chart

There is also another way to go about this task, which may be easier. If the movement was made in Germany, post WW2, we can safely make the following assumptions. If the movement is square and chain driven, it will require [email protected] lbs and [email protected] lbs. These are available in either 47mm or 43mm diameters.

If the pendulum bob is 8 1/2 inches or more, change that rule to [email protected] lbs and [email protected] in 47mm or 43mm. A movement that is rectangle in either chain or cable will use [email protected] and [email protected] LBS in 60mm diameter. This changes to [email protected] and [email protected] in 60mm diameter if the pendulum bob is 8 1/2 inches or wider. These specifications do not apply if your clock has 5 or 9 big tubes on the back. Also this rule is not for all Grandfather clock weights but the vast majority of the post WW2 German units.

Close enough is good enough

The weight specs list it as 4.7 or 6.6, however this is really being too picky. If you get it close to those numbers that is fine. In fact if you order a 4.7 lb weight, it may come 5.3 or whatever, but that is just fine. There has to be some sort of reference for the factory to label the Grandfather clock weights so it is what it is. Just know if it is a pound over that is fine. If it's a little under, that is fine also. They do not have to be exact.

Often wrong from the start

In fact, there is a lot of clocks in the world sold new with the wrong Clock Weights on them from the start. Clockworks will do a repair and they will say the clock ran for 30 years straight and come to find out they had Grandfather clock weights that were a pound or two too heavy. If the weights are a little too heavy it is fine. A lighter weight may or may not be fine because it may not trigger the movement to work as designed.

Grandfather Clock Weights Description - Conclusion

Grandfather clock Weights are not cheap mainly because they are so heavy to keep, ship, store, move from here to there. Sure one weight set of three is less than 30 lbs but that adds up quickly in a stack of weight sets. With that said, we don't want to ship these back and forth. It is best to get the right weights the first time. To return these is not an inexpensive or easy task. For example, suppose we charge $30 to ship these. They are wrong for some reason it's now $40 to get it back and another $30 to reship. UPS charges a fee to send a call tag for them to come back. That is $110 to UPS for no reason. So if there are questions, please ask.

Grandfather Clock Weights Stuck

The Grandfather clock weights can get stuck in the high position if over wound. Some larger clocks have over wind protection to prevent this. The grandmother and grandfather chain drive units often do not have this feature. When winding the weights up make sure the top of the weight can be seen when done. Never go to the point where the top of the shiny weight cover cant be seen.

Chime weight stuck

The chime weight is on the right as you face the clock and has the heaviest weight. 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. This will hopefully be enough to activate and run the chime on its own.

Time weight stuck

The time weight is the center weight which can be light or heavy depending on bob size. This is the hardest weight to deal with out of the three. Try pulling down some while swinging the pendulum. See if it starts running on its own when letting go. If this does not work, take off the pendulum. All it will have is the pendulum leader hanging on the back of the movement.

This will make it tick tock faster than if the pendulum was on. The leader will tick tock faster as you pull down some on the weight. The weight will then come down enough to run the clock. If all else fails, and it’s a chain driven clock, you would need to cut the chain in half, or break a link, to take the movement out of the clock. With the movement out of the clock it can be fixed.

Strike weight stuck

The strike weight is on the left as you face the clock and has the lightest weight. Only after the chime weight is operating correctly can you work on the strike weight. If the clock does not run through the chime sequence it will not get to where it strikes out the hours. With some cloth gloves on, or at least a cloth of some kind, pull down on the weight some.

Again, this is the same as making the weight weigh more. Doing this will make the clock strike. Advance the minute hand and let it chime each quarter until it plays the top of the hour song. Then pull a little on the weight when it’s supposed to strike out the hours. Keep advancing the time with the minute hand, as to make it chime and strike. Then slowly the weight will come down enough to be able to activate and run the strike on its own.

Changing a Clock Cable

Changing a clock cable requires the movement to be removed from the clock case. These instructions refer to post WW2 modern grandfather units of German origin, however all makes have a similar method. Swapping the cable is easy. There is a big hole and a little hole on the cable mount. The cable end fits into the big hole, then slides over to seat into the little hole. When locked in, it seats in securely. It's the same basic theme on both ends of the cable, meaning, one slot being in the cable drum itself and the other on the movement.

The cable drum side of the cable

To remove, lift the cable up from the oblong hole on the drum and slide it over to the big side. The cables have ends made of brass attached to them. These get slide over from the small side of the slot on the cable drum to the larger slot. It will then be released and removed from the clock movement.

The other end of the cable

The movement itself would normally have the plates attached for the cable ends. The cables have round brass ends on them and these lock into a plate on the movement. This plate will have a small hole leading to a big hole. To remove the cable it requires only lifting the end and moving over to the big hole and out.

Grandfather Grandmother Clock Chain

Grandfather grandmother clock chain by movement maker or links per foot LPF. Count the links on the old chain so it matches the LPF on the drop down menu. All Hermle chain driven units take 46.5LPF. Cuckoo clock chains are sold in a different section on Clockworks.

Clock Chain Installation

Clock chain Installation is simple. One end of the chain has a hook and the other end a tab. Loop the chain over the ratchet wheel so the hook end is on the side of the ratchet that will not come down if it is pulled. The weight is supposed to be suspended in the air and not come crashing down when it is hung in other words.

How to replace a chain & weight

I am interested in using grandfather clock chain for hanging pictures. Is there a recommended weight limit that you know of for this chain? Is the longer link chain (38 LPF) made of heavier wire, resulting in a slightly higher rating than the chains with higher link count?
Thank you
