Will you replace a barrel mainspring for a German RA wall clock made by Lenzkirch? It is labeled 2Q with ser. # 14239
Yes. Do you have the barrel out or do you need to send the entire movement?

Yes, I have the barrel out, but the geared base is loose and it does not want to fit back properly. Can you provide a new barrel with a new mainspring, or do you think you can fit the base back onto the old barrel
Mainspring swap is different than barrel work. We would need to see what is going on. The barrels are no longer made for that one. If you send in for a mainspring job we can quote for more work if it needs.

If I understand you correctly, you want me to send you the barrel with the mainspring to see what you can do to solve the problem. Is that correct?
Correct. See this link for starters

Time barrel spring out of a mid 50s Seth with an A400-000 movement. The barrel cap has an 8E stamped. Can’t seem to find that particular number. Any idea? Thank you.
Is this the strike, time, or chime side barrel ?

Should I be able to remove the mainspring barrel intact from a Kundo Torsion Clock? I can wind the mainspring and let down the mainspring but the barrel never seems to rotate. I’m thinking if I can remove the entire barrel unit, I can see why once wound it does not turn. Not comfortable removing the back plate from the entire movement.
Sorry do not have parts for that one

What is the Mainspring & barrel number of a Hermle 1051-020? I expect I will find replacing the barrel easier than the spring! All help received with thanks.
Hi,
The barrel number is on the cap of the barrel and can be seen when you take it out.
If the barrel is ok, we do offer a mainspring replacement service
https://www.clockworks.com/product/hole-end-clock-mainspring
Hole-End Clock Mainspring replacement-service
For a Hole-End Clock Mainspring replacement-service, all you have to do is send clockworks the clock barrel. Once we have the barrel, the old spring will be taken out. Then it is just a matter of installing the new mainspring. When sending in the mainspring, be please sure to leave the Hole-End clock mainspring within that barrel. The price for this service is $80 and it includes the cost of the Hole-End mainspring, as well as the shipping to return the barrel and new spring back to you.
What will be done
Clockworks.com will remove the broken, or worn, spring from the container in a safe way. The next step is to measure the thickness and width of the spring. The final measurement requires stretching out the old spring in order to get the length. Next we will use the mainspring chart for reference so that the correct spring will be put into the barrel. We will then pull that spring from the inventory that is already here with us at Clockworks. The installation of the spring will be done with a special tool called a mainspring winder. Once the new spring is safely within the barrel, the cap is snapped back into place and the mainspring is then on its way back to you.

Hi. I was wondering if you could help….I need to replace a barrel on a FHS mechanism but the backplate is just stamped with ‘8’ which I can’t seem to find anywhere. Did / do they make barrel No.8 or does it sound like it might be from a different manufacturer? Thanks for your time
you might try checking the barrel caps for a number. These numbers (if they are there) will let us know what spring is needed. Some are not stamped.
Therefor, removal of the spring from the barrel is necessary in order to measure the proper spring length, width and thickness. –Bob
Thank you !
I just removed 2 barrels from a hermle 150.010 mouvement from 1962 with a ‘8’ stamped on both caps. I did not take the springs out of the barrel since they where still clean and ok. You can measure the spring well when still inside the barrel. One string is 17 x 0,40 x ~1200 , and the other is 17 x 0,38 x ~1200 mm. Hope it helps. Greatings from belgium.
Why can’t I find a #53
How about #53 ?
Never heard of it.
Best to swap the mainspring inside that clock barrel because I dont think youll find that barrel outside. Not new anyway.
James
Many Thanks !

Hi
I have an old ship clock that I need a new barrel and main spring. It does not have any markings to tell me a size. The outer dimension with the teeth are 34.5mm and the other is 32mm without teeth. There is 73 teeth over all. What size do I need?
Thank you
do you have any numbers on the back of the movement itself? it may or may not be a hermle unit. if it is NOT a hermle, the spring barrels will not be compatible.–Bob
Hi. Please would you tell me the dimensions of the hermle 54 barrel.
If replacing a number 54 barrel, with a 54 barrel it would be the same dims.
James
Many Thanks !
