Please view these information tabs to learn about Hermle Clock Movement 140/141 series.

Hermle 140 / 141 Clock Movement

Hermle 140 / 141 Clock Movement comes in either the pendulum or non pendulum styles. Such as the pendulum unit 141-040 or the non pendulum balance wheel version such as the 140-010. This is a fourteen day unit, it runs the 14 days on a single wind up. They used to be made to run 8 days only. If the numbers are with a 5 instead like 151 or 150-xxx its an 8 day wind. All they did to make this happen was put a longer mainspring in the barrel, so if you have a 151 or 150 unit, the new unit to replace this is a 141 or 140-xxx instead. The rest of the numbers are consistent with the old, just match them up.

Movement Details

Hermle 140 / 141 Clock Movement series are all spring driven with 85 x 98mm plate size. They all take a #8 size clock key. What is being offered on this page is the movement only with out the pendulum, gong or dial. It will come as the movement itself with its hand nut, and if a pendulum unit it comes with the suspension spring and leader. The 141-040, 141-030, and a 141-033 all comes with a calendar. It is required to remove this calendar if you do not have the days of the month on your dial. Its easy, its just removing excess things so its not so involved. See the other tab about how to remove your calendar.

The speed

The time from deciding to repair the clock, to having it done is the very least it could be.It will ship out the next business day, unless its a special gearing. If this is the situation it will take about 4 days to ship as the movement. This is because the movement comes apart and put together with special gears. You can tell if its a regear unit if it has an extra charge on the movement that cost more than the rest of the movements. The choice is clear to get the new one instead of overhauling the old unit. You would get the movement in a week or two instead of months later, it will cost about a third the amount of a typical overhaul charge also.

Clock Movement 141-040 141-070 Compatibility

The compatibility between the clock movement 141-040 and 141-070 needs explanation and clarification. At one point in time the same number was used for both versions .

What is the difference between the 040 and the 070 Hermle units? The 040 series has a one hammer on the back whereas the 070 units have two bells on the back.

It is common to get an 070 as a replacement for an 040 gong strike. This is because the two units are cross compatible. To make it a gong strike, you only need to remove one of the hammers with its wire and take off the bells. The reasoning behind this is simply the cost of importing the movements from Germany. There are minimum purchase requirements for each series. So it only makes sense to import one series that is cross compatible. In most cases the customer leaves the bells and ditches the gong as the sound is better.

What is even more confusing is that there was a time when the 141-070 had a gong strike or a bell strike. It was the same number for both types. So what was previously known as a 141-070 is now referred to as a 141-070141-040. So, if you have a 141-070 see if it has one hammer on the back that strikes a gong, or if it has bells on the back. If you have the bells get the 141-070 and if it has a gong order the 141-040.

Clock Movement Calendar Removal

This section is referring to the calendar versions of the Hermle clock movement 141-040 141-030 and 141-033

Many of these units come with a calendar as indicated by the letter K after the movement numbers. This is the usual way some movements are supplied by the manufacturer. This way it covers movements with and without a calendar. In this way only one style is to be made, shipped, and stored ready to ship. So sometimes the new movement only comes into the country with a calendar attached. The below information will enable you to remove the calendar portion if needed to do so for the installation. Such as if the calendar tube is in the way of installing the new movement to the dial.

Removal

If you look at the new movement you will see two hex nuts on the front of the clock holding a small plate with gears under it. You will see that your old unit does not have this. Take these hex nuts off, and the plate, and slide the big gear off of the hand shaft. This big gear is just for the calendar.

There is a small C clip that blocks the hour hand tube from coming off. Remove the C clip with a small flat screwdriver and the hour hand tube will come off. Do the same thing with your old unit and put the old unit hour hand tube on the new unit. Note the exact position of the new movement’s hour tube. This position is important to note before taking it off and put the old unit’s hour tube in the exact position. What is meant by position is the humps on the snail looking portion that is attached to the hour hand tube. This has to be the same position on the new one just like it was on the old. If it is not the same then the hourly strikes will be off. The deepest slot is 12 o’clock and the highest hump is 1 o’clock.

Post Removal

The mounting posts where the hex nuts were located are still on the clock movement. Now if these are in the way of mounting your movement to your dial, they would need to be removed. The clock movement calendar removal would require these to be snapped off. This may seem harsh but if you get a pair of pliers and bend them down and up, they will snap off. This is because these posts are only pressed in by machine and there is no other way to remove them. This is the intent of the factory to have done, when needed.

Strike Count Reset

It is time to test the strikes and see if they are correct and that you have the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If you have one o’clock and 12 o’clock strike correct its all set. Tf it strikes 1 and 12 out with the correct number of strikes, then the rest is ok also.

If this is too much information then you can send in the old unit and the new unit and we will swap it out at for a charge of $30 Plus shipping.

About Hermle Clock Movements

Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint. To go and get it overhauled like you normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it. But as you see, since its a modern day unit (Post War German) it can be available new for a very good price. So what happens is you get a new movement instead of a fixed up old one, you get it in 3 days instead of 6 months. You will save hundreds of dollars doing it also.

 

All the Hermle clock movements we offer is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade. Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series. To get the movement from someone besides clockworks.com, you may not know what one you will get. Please know that Clockworks.com will only ship the best grade Hermle clock movement available, every time.

What you will get

Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also. If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader). If its a weight driven clock, it will come with new chains or cables and with pulleys. So this will be the movement with its hammer assemble on. This is the complete movement that comes out after you get in your hands and walk away from the clock with it. No weights, pendulum, chime block, hands, dial all this you have already usually.

When you place your online order you will get a receipt emailed to you providing you put in the correct email address. If you do not get a receipt, please check your spam folder for the receipt from us. On the receipt is the link to click for the instructions for your product. The Hermle clock movement ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear. The Hermle Clock Movements ship out UPS or sometimes FedEx. Never USPS unless there is a special request or you are an international customer.

Hermle Clock Pendulum Measuring

Hermle Clock Pendulum Measuring is done in combination of the CM number and the pendulum bob diameter. The CM will only be accurate to the pendulum length if the pendulum bob is small. If it has a larger bob it will be a longer pendulum. The larger the bob, or the heavier the pendulum, the longer it needs to be. Best to email [email protected] if you need the exact info on how long your pendulum should be. We would need the CM number off the back plate, and also how wide the pendulum bob is (round disk at the bottom of the pendulum).

The pendulum length (**cm) will be from the suspension post all the way down to the bottom of the pendulum nut threads. The length includes the pendulum from tip to tip, the leader it hangs on, and the suspension spring. This pendulum length will not always be exactly what is marked on the movement. There are other factors such as the pendulum bob diameter. The larger the pendulum bob diameter then the longer the pendulum length despite the CM length.

Conclusion

If the CM length on the old unit matches the CM length on the new unit, this is all that is needed. Sometimes it is required to use the old leader and put it on the new unit. If both CM numbers match and there is still a timing issue, it may had the wrong pendulum. The next question would be, did the clock ever keep time with the pendulum it had?

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky. By the time 20 or 30 years go by, the oil has solidified and is creating wear on the movements brass plates.

If you look at your old clock movement, you will see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round. With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.

This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function. To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.

New Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

Hermle Clock Movement Aliases

Hermle produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.

The best disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . This is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart. However the Seth Thomas chart is not very accurate, please see instructions on that page.

It is best to replace the clock movement if either of these names are on the movement automatically. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.
