Mechanical - Quartz Clock Conversion Kit

The Mechanical - Quartz Clock Conversion Kit is an economical alternative to the mechanical replacement unit. The clock will operate by a battery, and still look and sound the same. Installation is easy with this kit contains everything you need.

It has the chiming quartz clock movement and the pendulum drive. (You only need to pick out the hands) With just some minor alterations, you will mount the movement to the back of the dial. Then mount the pendulum drive to the back of the clock case.

Heavy Duty Pendulum Drive

5 1/2" x 2 5/8" x 2"

Heavy duty Clock pendulum drive
No Chime Heavy Duty External Quartz Pendulum Drive. The strongest pendulum swinger available that operates by a battery. Tested with 2lbs 8oz (1100 grams), 44 inch long metal lyre pendulum with 8 ½ wide bob. Operates on two C-cell batteries (these do not come with the drive).

#QU40 Four Melody Chime (Best Sound)

4 9/16" x 4 3/4" x 1 1/8"

Chiming Quartz clock movements
West Ave Maria Bim Bam Hour Strike Song options: Westminster every quarter or Westminster, Ave Maria, Bim Bam options on the top of the hour only. Includes a light sensor and will be silent automatically if its dark in the room. Hands for this unit are sold separately.
  • Volume control
  • AutoNight Silence Switch
  • Light sensor for chime off

About the movement for the Mechanical - Quartz Clock Conversion Kit

The QU40 quartz clock movement is the best sounding unit on the market. It will sound just as a mechanical clock chime. It will also have some additional benefits.

The volume control can make it very loud or soft and this was not possible on the old mechanical unit. This quartz unit also has multiple chime options and an auto night silence switch. QU40 Instructions

Mounting the movement

The QU40 quartz clock movement will mount to the back of the clock dial. If the clock dial has phase of the moon it can have gears in the way of this. The QU40 would need a flat surface to mount up to the dial so you will need to remove these things.

About the pendulum drive

This is a new product on the market. Never before was there such a strong pendulum drive made like this one. It will run any pendulum length or weight that a mechanical unit has run in the past. It will mount to the back of the wood clock case with wood screws.

Extra Parts

The quartz unit is replacing the mechanical movement so there will be parts you do not need any longer. The new quartz movement will come with hands so you do not need these either. You will no longer use the Chime block so that can also come out.

The only things you will need from the old mechanical kit is the dial and the pendulum. Weight shells also if they are to be hung as decoration to have the clock look the same.

Weight modifications

The clock weights are heavy so it is best to make them lighter. When you remove the weight from the outer shell, it can be hung for decoration. You can also use a portion of the chain or cable from the mechanical unit to hang the decorative weight shells. With a little attention the clock can look just as it did with the mechanical movement.

What will not work with the Mechanical - Quartz Clock Conversion Kit

Dial's clock moon dial disk that indicates the lunar cycles will no longer spin. If the clock has a moon dial that is. If there is a separate second hand sweep portion on the dial, the quartz unit will not have this feature.

There will no longer be a second hand spinning with in that circle. Someone could epoxy the second hand to the dial so at least it looks right.

The point of no return

When a Mechanical - Quartz Clock Conversion Kit is done, there is no going back. At least it would not always be easy to go back to a mechanical movement. So please be sure this is what you would like to do for the long run.

Steps to Take - the short version

  1. Remove the old movement and all parts
  2. Mount the quartz movement to the back of the dial
  3. Mount the external pendulum drive to the back of the cabinet and hang the pendulum.
  4. Remove lead from weight shells and hang the shells for decoration
Chiming Quartz Instructions QU40

Features

  • Westminster every quarter, and then strike out the hours
  • Or Westminster / Ave Maria / BimBam on the top of the hour only
  • Auto Night Silence Option (10pm to 6am)
  • Volume Control
  • Second Hand Option
  • Pendulum Option
  • Light sensor auto chime off
  • Takes Two C-Cell Batteries

Premium Chime Clock Movement QU40 Instructions

  1. Connect the speaker to the movement
  2. Rotate handshaft clockwise until you hear a faint click sound. Then install hands at 5:00
  3. Insert the proper C-cell batteries into the movement. Note that the positive end of the battery faces downward.
  4. Double check to see that the hands are at the 5:00 position. Then press the gray RESET button at the bottom of the back side of the movement. This will set the electronic strike to 5:00AM. Rotate hands to 6:00 and note that it will strike 6 times. If everything is correct advance the hands to the correct time.
  5. Next, choose the melody in which you wish the movement to play. Note when in the 4x4 mode it will chime on the quarter and half hours as well as on the hour.
  6. When in the 4x4 mode, it may take a complete hour to correct itself after the time set knob is put to the correct hour. However this is completely normal.
  7. For night chime silence, set the sound lever that is on the back right hand side to PM 11:00-AM 5:45 Night off. This will be the auto night shut off mode and will shut the chimes off between 11 and 5:45AM. For 24 hours, move lever to the 24HR mode.
  8. The MONITOR button demonstrates the hourly chime.
  9. The SET button advances the strike one hour. However, this will not move the hands
  10. Very Important! Never turn the hands backwards. If setting the time from the back of the clock, turn the time set knob on the back of the movement so the hands move Clockwise only. Likewise, if setting the clock from the front, turn hands Clockwise only.

I have a grandfather’s clock I’m sure because it’s light wood and not real wood it wasn’t very expensive, I’m guessing maybe $800 or less. But I like it I wish you could let us upload pictures of what we’re talking about. I want to restore it, somebody actually started in the trash outside their house. And my lover and I put it in the back of a pickup and we forwarded home. It’s a real time mechanism that had weights and actually have long chimes in the back I would love to restore it or replace the inside with something that is going to sound just as good and keep just as good time. Am I looking for something that doesn’t exist? I don’t even know who makes the clock.

I have a Becker wall clock with original face, case and pendulum. The movement is beyond help. I do have many functioning German wall clocks and I’d like to add this one because the case is lovely, as is the dial and the pendulum. I am aware of your heavy duty pendulum drive and your #QU40. I understand that the hands would not retrofit, but can the original pendulum be installed with a bit of ingenuity?

  • I have two QU40 movements installed in clocks. One upstairs and one downstairs. Something has happened that I cannot explain. Both clocks have started chiming two times less than the proper number. The time itself is right on.
  • I will reset both clocks at the end of daylight saving time but there must be some reason for this. Do you have any ideas or suggestions why both clocks would do this at the same time? Thanks

Want to convert old Sear’s kitchen clock to battery/ quartz with kit QCON. There is a inch and a half hole in the center of the original face plat that makes room for a round plate that attaches to the old clock movement. I would like to use the original face plate. I was wondering if you have a part solution for this issue? Maybe I need convert with a new face that has a correct size hole to receive the new shaft on the new clock movement. I am and very handy and have lots of tools. I could send pictures if that would help”
Thank you

I just installed the QU40 Quartz conversion to a mantel clock without a pendulum. The clock runs but is a little slow (loses about 2 minutes per hour}. Can you adjust the clock? Also, the chimes have been set correctly according to the directions but will not chime automatically. The Monitor button shows that they are chiming the correct hour.
Where is the light sensor? How can it see light if it is enclosed in a clock case? I have tried putting it under a bright light to see what happens. No chimes. Do you have any ideas on what to do now?

Dear Sir, i currently have an 8-Day mechanical Cuckoo Clock that is not working. I bought this Cuckoo Clock in Germany. Is it possible for me to convert this mechanical clock to a digital battery operated clock. How much will it cost for the conversion. Where is the station that i need to send my clock to…?

Please let me know

Hello. I have two Emperor mantel clocks that my father put together from kits in the 1970s. Both had mechanical movements. He replaced one with what appears to be an MT-13005 battery movement later in the 1980s. I found that information at https://clockinfo.com/posts/300. This looks exactly like that movement. Now the mechanical movement of the second clock has broken. I’m looking for an economical battery movement to replace it. The clock does have the moon dial, not just the Tempus Fugit plate like the first one does. What options do you have to try to restore this clock to running condition? Thank you.

I purchased the conversion kit but no instructions included on removing old hardware and installing? Do you have step by step instructions? Also, not seeing where you might install the chains and weights on the kit mechanism. I understand they will be for display only but what will they be anchored to? Maybe instructions will include this?

I am hoping to convert my grandfather showcase pendulum clock with Urgos 03096 mechanism to quartz. The clock currently displays month, day and date as well as phases of the moon. Your description says moon phase mechanism may interfere with installation of your QU40 quartz clock movement.  
Does your QU40 drive the month, day and date mechanism that is currently part of my clock face so they will continue to display correctly? If not, is there another movement that does?

Two questions for QU40. I’m thinking there will be many days I would prefer the unit to be silent. I propose to mount a small switch on the speaker wires. Can I get by with just switching one line, or do I need a double pole switch? Nest question, the remote battery housing used with the pendulum unit is very handy. Is there such an option with the QU40?

Just finished installing the Quartz Conversion Kit in a 1983 Dold corner grandfather clock. Went well considering the tight space in the cabinet and my arthritis. Unfortunately, I did something at the end that caused the time/chimes to be 5 minutes fast. Given the proscription to backing up the hands, is there a way to pause the movement? I really don’t want to do the initialization over — there’s no easy way to get to the back of the movement.

Day 1 of my mech to quartz conversion and it seems to be fine – just looking for info on the way the light sensor is supposed to work. Probably an update is needed to https://www.clockworks.com/clock-repair/quad-clock-instructions.html to cover it. Does it over-ride the fixed period shutoff or also works if the clock is on continuous chime and lights on? How much light will keep it chiming? Sure trial and error will get us there, but you guys already know, and sharing is good!
Same as hanging the pendulum on this driver, no info. I have a supposed max weight 250g pendulum and it rips away, like the drive could easily handle double the mass! Hanging it was just a matter of carefully squashing the pendulum top slotted bit over the bar so it was square but not gripping hard so can easily be unhooked but is stable in operation; another instructional oversight.

How do you attach a pendulum to the pendulum drive. I ordered the hd pendulum drive there were no directions, and no clip provided to attach my old pendulum. The plastic looks fairly delicate and I don’t want to break the plastic arm. What is your suggestion, or is there a part I should order?

Also I ordered your chime movement as part of the conversion kit. Again no directions, or diagram. What are the two wires that extend with the ends bare, and connected at the end. They appear to have no function. I attached the speaker wires.

Thanks for your help. I am excited to finish this project.

how long of a pendulum will a #qu40 movement use

Tom Graber
Tom Graber
3 years ago

This QU40 movement will fit flat on the back of the dial which is brass and 1/16 inch thick. I think there should be 2 to 3 threads on the 5/16 post to secure the movement if it can be put directly on the flat brass dial back. Does this sound right?

Tom Graber
Tom Graber

Is there a switch on the clock movement to stop the pendulum, as you would use the heavy duty pendulum drive? Is the circuit board inset so it isn’t squashed when attaching to the clock face, or is that not a problem? You offer 3 sizes of shaft lengths. It would seem that having a bit more shaft would be easier to work with if you are mounting just on the back of the brass sheet of the face. If it proved to be too long could you just shim it with a couple washers, or is that not recommended. 5/16” would probably be enough mounting directly on the back of the movement plate, but the 7/16” would work for sure.
What do you advise? Thanks.
