If you mean the cover with the posts sticking through, just pry slightly at different points around the outside edge, should pop right off. If you mean the plate with the mounting posts attached, you will want to put the assembly in the freezer for 3-4 minutes to collapse the bellows. Then you can remove the plate by pushing down and turning until the bayonet mount comes apart. NOTE: you do not want to leave the bellows at room temperature without some sort of restraint. If it expands to its maximum, it could crack the seams.I haven't been able to get the bellows cover off yet. Don't want to break anything. Any tricks to that?
1) If the spring is fully wound to equilibrium with the bellows, it will not continue to wind until the clock has run enough to let the spring down a bit. As Ed says, if there is some binding in the mainspring, this could take a while, or fail entirely.Thanks, Ed. Would that keep it from winding? It seems to be running on the spring power well at this point. Two days now.
If you checked the bellows assembly (see attached), and it is OK, then the spring that does the cold cycle 'pushing' is OK. The spring that moves the chain in/out does not follow the bellows - yes, it gets pushed by the bellows (moving the chain out and arming the ratchet), but when the bellows contracts, the chain spring will only expand as much as the winding mechanism lets it. The chain spring could be weak (it happens, but not likely), the chain pulley could be binding (common on the 540, but we still don't know what clocks you have), or the mainspring could be binding (common in older clocks if the mainspring has never been serviced).The other one will wind, but on the cold side of the wind the internal spring doesn't seem to want to push the bellows enough. So it appears to want drastic temperature changes to wind. Any ideas about that? I wound it about 3 turns by hand and have it running as a test now.
And the fix for this is oil? Or a new mainspring? Just curious.What I find on virtually all the Atmos clocks I disassemble is a dry mainspring.
Got it. Didn't see that one.You have to read Victor's comment.
a library with good books and charming atmos-sphere!Here 'ya go, Victor. The one on the right is running. I need to clean up the bottom where a presentation plaque came off.
