  • Volume control
  • Includes a pendulum
  • AutoNight Silence Switch
  • Light sensor for chime off

About the movement

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 added benefits. The volume control can make it very loud or soft this was not possible on the old mechanical unit. This quartz unit also have 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 these things would need to be removed.

About the pendulum drive

This is a new product on the market. Never before was there such a strong pendulum drive produced 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.

Parts no longer needed

Mechanical movement is getting swapped for the quartz unit instead, so it is no longer needed. The new quartz movement will come with hands so these are not needed either. Chime block will no longer be used from the clock case and can be removed and discarded. The only things needed 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. With the weight removed from the outer shell, it can be hung for decoration. A portion of the chain or cable from the mechanical unit could be used 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

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 is used, 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 related 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

I will be building a grandfather clock soon and I was considering getting the quartz conversion kit rather than a mechanical movement. I was wondering how the size of this kit compares to other kits. How much does the pendulum swing and how wide would the case have to be? Also, what would the depth of the case have to be for this particular kit? Thanks

Regarding the “post length”. I assume you mean the thread length portion, not the total length. Is that correct?

Hi. The clock that I have has a pendulum. I want to buy a quartz conversion unit. I’m not sure which one to order. Please help

I have a Emperor grandfather clock, model 100M. Circa 1970. Does your instruction manual include removal of the old clock face? If its a hassle can I purchase a new clock face to fit?

I have a Hermle 1171-850 movement with a Lyre Pendulum. Will this conversion kit fit? and what functions will it replace. I assume:
1. Lyre pendulum movement (with optional pendulum drive)
2. quarter hour chime (west only)
3. auto night shut off
4. second hand support
5. West or Ave Marie hourly chime
6. I have no use for the supplied pendulum? is that correct
7. Can I use the original second hand; hour and minute hand with the new quartz movement?

Does the quartz movement or the pendulum drive provide a tick tock sound?

I want to scrap my mechanical (regula movement,bellows,coco bird, Chain and the rest )and put a quarts replacement in the case…….could you recommend a smaller conversion kit . The songs aren’t important the hour chime and half-hour coo-coo would be nice….I like the fact of having night silence options……..I really just enjoy the tic-tok and hour notifications……can you suggest…..

Hi I have an emperor grandmother clock. Can I use the original hands for it with the conversion kit?

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.

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?

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.

Looking for a quartz movement 812062 originally from s. Lacross

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.

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.

What is the diameter of the shaft where it passes through the clock face QU40 model. I’m converting an old school house regulator clock to quartz. The hole in the face measures 11 mm (approx 7/16″)
