Mason-Sullivan clock movement Identification
Mason-Sullivan clock movement Identification
If the movement says Mason and Sullivan it does not mean it has a Mason-Sullivan movement number. Often the use of their own numbering system was on the clock movements. This was done in the later years of the Mason and Sullivan company history. Generally speaking, it is best to match up the ID numbers on the clock movement identification chart if not already done. If the clock movement number ends with an X, then the Mason and Sullivan chart page is the right place to be. If the number does not end with an X, please refer back to the clock movement identification chart.
Why convert the number
For the most part, the Mason and Sullivan number system is not helpful to determine what the movement is. After the conversion everything will be known about the movement and who made it. In the long run, this will allow for the purchase of parts or a replacement movement precise and accurate. Moreover, the conversion number will tell us the movement plate size, hand shaft length, hammer location and more.
How the new one comes
The new movement ships the same or next business day already with fresh oil and ready for installation. If it is weight driven it will come with chains or cables. If the movement is a pendulum version it will come with the leader and suspension spring.
Support
Clockworks provides the instructions for installation and also support for the clock movement. This family has a combination of over 100 years as clock makers. Questions and problems are taken care of even after the manufacturer says it's out of warranty. Basically if needing help just ask. There are not many clock makers around anymore, so not only get a response but it will be correct answer and what makes the most financial sense. The manufacturer warranty is three years on a new clock movement.
Conclusion
Identification of the Mason and Sullivan clock movement is the first step. It will grant the customer the ability to shop for a movement or components. Without the identification process everything is in the dark so to speak. It is like a secret code that needs to be cracked. It can get confusing but we are here to help. When contacting us the movement number will be the first thing we ask for. If having trouble locating it, email a picture along with the question. This way we can see what you have in the clock. Once the movement has the proper identification, it is a good idea to write it down and keep it inside the clock case for future reference. That way this whole process does not need to take place again.

I need new mechanical works for a wall clock (no chime) made for us at least 30 years ago, the Mason & Sullivan number is 3351X which is not listed on the M&S chart. If this is no longer available, is there a works the will exactly fit the same frame and clock face construction?
I do not have reference for that one. Can you email some pics of this clock and the movement to clockworks@clockworks.com so I can see what one it is please

I have had a Mason and Sullivan clock movement for almost 40 years. The numbers on it are 141-030. It’s 4″ high and 3 1/2″ wide. About every five to ten years, it gets bound up. Each time, I get it repaired. It is a Shaker style clock with a pendulum, hand made from native wood by a close family friend. It’s a family treasure our three adult children will battle over.
Hi,
Here is the direct replacement for your Movement:
141-030K Hermle Clock Movement – 1-800-381-7458- Clockworks – Clockworks
If you clock does not have a calendar (days of the month) Please see these instructions:
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 the removal of 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
Look at the new movement and see two hex nuts on the front of the clock holding a small plate with gears under it. See that the 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 the 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 the movement to the 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 using 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 the hour hand tube in the correct position. Make the clock strike and count how many times it strikes. If 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.

I have M&S movement I acquired nearly 30 years ag. Two chime springs, one weight for the clock. Has opperted fine over the years.
Recently wound the chime springs, now it will not chime. Any suggestions as to the problem and how to fix?
M and S went out of business over 30 years ago. Those are 25 year movements. Its time to replace that one with the new one. The new one is half the price of restoration, lasts 20 – 30 years, get it now. Are you interested in a quote? If so, please email a pic of that ones back side where the numbers are, and email this to clockworks@clockworks.com

Built Railroad Regulator clock model 6675X. Quit running. Took to clock repair man, said it couldn’t be fixed. Wanted to replace works with a quartz movement.
could I get a replacement movement from you? It’s a calendar, bim-bam chime movement.

Sorry do not have the battery operated calendar units

I have a Mason&Sullivan Vienna Regulator. The movement has the number 3325, but it is not on any of your lists. I need to know who made it and what model number so I can order repair parts.
Hi,
Not sure what that is, need to see it to ID the unit. Please email some pics with this very same question with it to clockworks@clockworks.com and so we can narrow it down
