Howdy all,
I'm about to work on this Korean clock for a friend. Pivots look good upon cursory inspection. My dilemma is how to release the suspension spring. Looks like the only option is to gently bend out the two supports on either side of the spring? The holder is riveted to the plate. My other concern is the 31 day springs. I've never taken a movement apart that has these powerful springs. Any suggestions (other than don't do it)?

I think i would do the same, spread those tabs to get the susp spring off.
I dont find these springs any more stronger or hazardous, just longer and a bit more difficult to work with.

The 31 day springs are not any more powerful than the 8 day variety, but will fill your work room with spring when you let them down on your spring winder. Take good note of how those spring tabs at the base work. They HAVE to go back in there, exactly like they are. To me, it's easier to put them in last.

I've never had any need to remove the suspension, and just work around it. If it's broken, then take it off to replace it.
For the springs, let them down first, then one at a time, take the nut off and remove the steel pieces that are there to force the spring away from the movement. Then put the nuts back on, and wind it up again, restrain the spring (I use wire), then let them down again. Re-install in an opposite manner to get the steel pieces back in place.
