When replacing the QU40 Chime-Pendulum Clock Movement, you will need to measure the post on the old unit. So then you can match it up with your new chiming quartz movement. In addition, the post is the part that goes through the dial (face) and mounts from the front.

Removing a Bad Unit
The first step to replacing a quartz movement, is to be able to get to the movement from the back and also the front where the hands are.1. Getting to the dial
There are many case designs and styles and there is no telling what way your clock case is made to get to the dial (face) of the clock. Sometimes it is very easy to get to the dial and hands, other times the dial has a glass covering it. You may find yourself trying to figure out how the clock case was put together, in order to take it apart enough to get to the dial. You may have to remove some screws, or if there is a bezel you may have to bend the bezel tabs a little to get it off. Once you're at the point where you can remove the hands, and also the back of the quartz unit, you're good to start replacing the unit.2. Removing the hands
If there is a second hand on the clock, grab it with your thumb nails and pull straight off of the clock to take it off. There are two styles to the minute hand. One type has the nut holding it down and the other kind has a minute hand only held in place by friction. The second type has a perfectly round hole in the hand in comparison to the oblong hole of the first style. Obviously, the friction fit with no nut style just pulls straight off like the second hand did. The other style (the kind we sell) has the nut on the top of the minute hand to hold it down. To take this off, hold the minute hand still as you turn the nut to the left with needle nose pliers to loosen the nut so you can take it off with your fingers. Next is the hour hand, this is only a friction fit with a round hole in the hand, the tube its on is tapered fatter as it goes down into the movement. Simply twist the hand and pull it toward you until it comes off.3. Removing the hex nut
Then you will see a hex nut (six sided nut). So, use the same needle nose pliers to just turn the hex nut some to the left so you can unscrew it with your fingers. Of course, once the hex nut is off, the quartz clock movement will just fall out of the back side of the dial (face).
Dial = The clock face that the movements post goes through. 
Post = Threaded portion on the movement that takes the hex nut. 
Hex Nut = A six sided nut that threads onto the movement post.
Hanger = Included, but optional, steel part to hang clock. 
Hands = AKA needles, arms, pointers. Indicates hour and minute. 
Second Hand = The optional skinny pointer that ticks out the seconds.Quartz Movement Assembly
These are the assembly instructions for the time only quartz clock movement into the clock case.- Place hanger on post (optional)
- Place black washer on post (optional)
- Put post through the clock dial face
- Slide the brass washer onto the post of the movement that is sticking out of the clock dial face
- Put hex nut on post and tighten to hold movement to the back of the clock face – you may use needle nose pliers to get a tighter fit, however do not crank it down so tight that it ruins the clock face.
- Push hour hand on the post (smaller of the 2 hands with round hole). This is a friction fit and should be pushed all the way down on the post without it touching the clock face.
- Put the minute hand on the post
- If using a second hand, skip to step 9. If you are not using a second hand, screw the cap nut on. You are done.
- If using a second hand, screw the small donut on top of minute hand and then push the second hand onto the pin in the center of the unit. You are done installing you're brand new quartz clock movement !
Movement information
This QU40 Chime-Pendulum Clock Movement is a four melody chime unit and is unique as it has a light sensor. If the lights are off, or it does not see light, it will not chime. Easy! Simple! So what this means is if you want to just set and forget, and not bother with turning the chimes on or off during the night, this unit will be the one for you. Of course there is a overnight automatic shut off that is an option as well. In addition, the pendulum, clock hands and the second hand are all sold separately. Congratulations on the purchase of our new QUAD quartz movement. In fact, they are backed by our one year warranty. Also, with their amazing Tubular Chime sound, these movements should provide years of worry free performance. Furthermore, this unit has a premium sound quality and takes two C-cell batteries. The speaker is on a wire so it can be mounted anywhere in the clock case with two wood screws.
- Volume control
- Supports a 16 inch pendulum or shorter
- AutoNight Silence Switch
- Light sensor for chime off
QU40 Chime-Pendulum Clock Movement Notes
Movement
The new QU40 Chime-Pendulum Clock Movement has step motion timekeeping accuracy and includes a time setting knob on the back of the unit. The knob on the back is so the time can be set by the back, in case you have the hands not easily accessible from the front. This is a pendulum unit but you can use it with or without the pendulum. The pendulum motion does not have anything to do with the timekeeping on this unit.Sound
This is the only unit with four options for the chime. Choose between Westminster chime on every quarter and then striking out the hour, or choose Westminster or Ave Maria or Bim Bam on the top of the hour only. The light sensor is easy, if it does not see light, it will not make noise. The sensor is on a wire, and you can tuck it in just so it can detect if there is light or not anywhere in the case that light would fall upon.Hands
Any of the hands we sell for quartz clock movements will fit this unit. As far as the quartz units go, we only have the standard American “I” shaft units and hands. This means the hour hand will have a round hole and the minute hand would have a oblong hole. The hour hand goes on as a friction fit, then the minute hand goes on the upper post with its nut. Use a second hand only if you want to. All hands are sold separately and are offered here as well.Pendulum
This movement supports a pendulum that is 16 inches at its longest length. However you can shorten it to anything less than 16 inches with ease. The pendulum has three bob diameter options to choose from, the bob is the round disk at the bottom of the pendulum rod. Please note although this is a pendulum unit, you can use it with or without the pendulum. If you do not use a pendulum, you can just lock the pendulum swinger to one side and not use it.Mounting Post
The movements threaded post comes in three lengths. This is the fat part with the threads that takes the hex nut. This post length is what we measure, the actual part that the hands go onto sticks out another ¼ inch beyond this measurement, but we do not count that in the measurement. The post lengths available for this unit is either 5/16 long or 7/16 or 11/16 long. The posts are all 5/16 wide, and fit into a ⅜ dial hole.
Features of the QU40 Chime-Pendulum Clock Movement
- 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
Instructions for the QU40 Chime-Pendulum Clock Movement
- Connect the speaker to the movement
- Rotate handshaft clockwise until you hear a faint click sound. Insert hands at 5:00
- Insert the proper C cell batteries into the movement. Note that the positive end of the battery faces downward.
- Double check to see that the hands are at the 5:00 position. 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.
- 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.
- When in the 4x4 mode, it may take a complete hour to correct itself after the time set knob is turned to the correct hour. This is completely normal.
- If you desire that the sound be shut off at night while asleep, set the sound lever, which 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. If you wish to have it strike all 24 hours, move lever to the 24 HR mode.
- The monitor button is to demonstrate the hourly chime.
- The SET button is to advance the strike one hour. This will not move the hands
- 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 Counter Clockwise only, if setting the clock from the front, turn hands Clockwise only
I have a thin metal clock face. You state I should order the 3/16″ size post, but you only carry the 5/1″ post. What can I do? The clock has a slightly curved glass face.
Put a spacer between the movement and the back of the dial if need be

I just received my Premium Chime Clock Movement QU40. There is a holder for an AA battery which is not shown in your clock description and installation instructions. What is the AA battery for? My order number is 338191.
Yes needs the AA battery also. It is for the time keeping aspect

What is the distance from the front face to the pendulum? Or how far from the mounted surface to the pendulum?
Also, will this unit handle five inch hands?
The bottom of the pendulum hanger is about 2 inches down from the hand shaft. The pendulum is 16 inch at its longest, but can be shortened to whatever. Yes it can take 5 inch hands

What Qu40 quartz movement kit do I need to convert My Seth Thomas 120 movement Mantel Clock to the battery operated clock. I would like to order this if possible. Thanks, Jerry.
Not easy. Would need to drill the dial center hole wider to take a 3/8 post, the post could stick out too far to shut the convex glass and so forth.
That is a higher value movement. Are you interested in our restoration service ?

Further to my question, I have an original Sessions Ramona clock the works of which are gone and have been replaced with a simple AA battery quartz drive, and the pendulum just sits fixed to the case. So I would like to improve it, with a pendulum drive and appropriate chimes.
Good plan, any questions ?

Is their an electronic clockworks that emulates the 1905 Sessions Ramona clock, which I understand had a bell that is struck on the half hour and a coil chime that was struck for the hours?
Sorry but no

How do you do “Fall Back” going off daylight savings time if you can’t turn hands back?
Take the battery out for an hour, or go forward around to the time again

I purchased and installed the chime-pendulum clock movement. The clock movement is working just fine. However, after working well for several weeks the pendulum stopped working. The clock is level side to side and front to back. Of possible, please suggest what I can do to get it to work.
Make sure the batteries are good and strong, the pendulum is not rubbing the wall or anything else also. The unit should be close to level within the clock

I have a Waltham 30 day wind Vienna regulator wall clock in which I want to replace the works with a battery operated works. The location where the clock is located is not an easy access to be wound (even if it is only thirty days!) and so I’m thinking battery operated is the way to go, The lyre pendulum that I believe is original to the clock weighs about 7.2 oz. Will the original pendulum work with these works or will I need to also order they heavy duty pendulum drive? Thanks so much for your help.
It will come with a pendulum if you order it as such. Best to get the pendulum we offer with the movement to be sure. This way if yours does not work on it you can use the one shipped

On the Chime Options switch, what does CDS stand for? The illustration about says “24 hour if there is light”. How do I set the clock to strike all the time?
Chime options
1. PM auto Silent
2. CDS 24 hours chime
3. Chime off

Update. I confirmed that the illustration above is accurate in that the photodiode of the clockworks does need to be exposed to light in order to chime during the night. I confirmed this by 1) shining a small flashlight on the photodiode during the night, and 2) covering the photodiode during the day. In the first case, the clock chimed during the night. In the second case, the clock did not chime at all.
Is there a work around the bypass the photodiode?
Thank you,
Joe Knight
There is not. If there is no light, there is no sound.

I’m interested in the QU40 movement, however my pendulum is 24 inches. It’s a Powel Westminster Quartz clock, second hand and pendulum so figuring the QU40 a good replacement. It not this QU 40, do you have another suggestion for replacement??
If the pendulum is very light it will work maybe. Typically it takes a light 16 inch pendulum. If its too heavy it is needed to get the heavy duty pendulum drive also, and this would mount separate in the case behind the movement. This link

Is there a way to slow the movement down? Mine always seems to be running fast and I have to back the time a min or so bi-weekly
There is not an adjustment, usually they are dead on.

How far from center, on each side, does the pendulum swing?
It depends on the length of the pendulum rod, and this is variable depending on what length it is cut by you.
It is 16inches at longest but can be cut to whatever length shorter as described here https://www.clockworks.com/product/quartz-clock-pendulum-bob
It also depends on bob diameter chosen
If the swing ends up being to wide it is possible to put some duct tape over the magnet too lessen the strength and thus the swing.

How do I get the quarter hour chimes to work
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 4×4 mode it will chime on the quarter and half hours as well as on the hour.
6. When in the 4×4 mode, it may take a complete hour to correct itself after the time set knob is turned to the correct hour. However this is completely normal.
7. For night chime silence, set the sound lever located 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 is used to demonstrate the hourly chime.
9. The SET button is used to advance 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 had to reset my time a couple of times, mostly because it was off just a bit. The instructions are OK for the initial setup, but unnecessary for any adjustment to ensure the chime started exactly on the hour. I followed the instructions but I could never get it quite exactly where I wanted it. The chime was always a few seconds late or early. So, I simply moved the clock ahead to just before 5, and with the battery already installed, waited until the second hand hit 12. I hit the reset button and then moved the time to the correct time. This method works perfectly and you don’t have to remove the hands, and turn it back until it clicks and then hit the reset.
That is great to know, I do appreciate the feed back

Can this movement drive a remote pendulum? Movement #QU40 Chime Pendulum Clock Movement. If not, do you recommennd one that can with chimes.
Thank You
The QU40 comes with a 16 inch pendulum rod – if that length is not needed, it is segmented every inch so you can measure the length you need, bend it and snap it off.
Let me Clarify – The pendulum in the clock I am working on is not in the same plain as the movement so it has a remote module that plugs into the main movement. There is about a two inch different from the face of the clock to the location where the pendulum connects to the pendulum drive module (similar to your Heavy Duty Pendulum Drive)
Oh ok – so we have a pendulum drive that is designed just to run a pendulum and is capable of handling a large lyre pendulum.
If you want the clock to chime then there are non-pendulum movements that you can get in conjunction with the pendulum drive.
All of these items and hands can be found at this link: https://www.clockworks.com/clock-movement/chiming-pendulum-quartz-clock-movements.html
Thank you. Going to try one last thing to make the one I have work, if it doesn’t I will be ordering new ones from your shop. I usually only work on mechanical clocks so this is new territory for me.
Thank you for the help.
