I recently purchased a nice little Badische #11 clock movement in good working condition. It runs flawlessly for a little bit and then gradually stops, even when I have it fully wound. I noticed that the pendulum suspension spring is slightly bent. Does it need to be replaced? How can I get it working for the full 8 (?) day duration? I am new to clocks and this is my first mechanical clock movement and I don't really know how to repair it.

Could you post some pictures of the clock for us? Also, you might want to read "Beat Setting 101" too. Its at the top of this forum under "How To Do It" articles.

I did get it to run for almost 3 hours today. I’ll see how long I can keep it running but here’s some pictures of the movement. I do think it's something with the beat of the clock. I didn't do a great job mounting it on this temporary stand. I think I installed it slightly crooked, because you can definitely hear that it is slightly out of beat.

One thing I notice is that the pendulum hanger is touching the back of the crutch loop. It needs to be hitting center position.

How would I fix this issue? I made a minor adjustment to the crutch and it sounds more or less in beat now. I have also had it running for the past few hours. EDIT: I fixed the position and now the pendulum rod hits the center of the crutch, but now it has a weird ticking sound and falls out of beat really fast.

Just bend the crutch wire, much like you do for setting the beat. But be careful not to put enough pressure on the escape wheel pivots to bend one.

It is good now, perfectly in beat, but it sounds like this "clink-tick-click-tick" because of the pendulum rod hitting the sides of the crutch loop. Is this normal?

No. The crutch loop should be closed a bit. You want enough movement there to allow the hanger to move easily within it, but not too sloppy. A paper width on one side of the hanger is enough. A tiny smear of oil is OK too.

Thank you so much! My movement is now working like the day it was made! If I ever do need to oil it, what is the best oil for antique clocks?

You can use the same oils you would use in a modern clock movement, but even that is a subject of much debate! :p More importantly, you'll want to clean the movement before re-oiling it. Just putting more oil on a dirty movement is a recipe for wearing out your clock faster.

I've personally used Etsyntha 859 on a hundred year old German grandfather clock movement that has been running well for 4 years now. It's expensive (~$20 for 3.5 ml), but one bottle will last for dozens of movements. At least one NAWCC author has suggested Mobil 1 5w-40 for all pivots. And there are tons of recommendations for various viscosity Moebius oils on this board.

Cheers,
Dan
