Clock runs for a few hours and stops..
Weight shell hanging.
Hi Folks, I just want to validate I did not mess up something simple on the SB14. My clock runs for a few hours and stops. I am going to take it down and check the fit in the frame of all the arbors I suspect some might be too tight.
For the few hours it runs it is pretty accurate and everything seems ok. Last night it ran for 10 hours. When it stops just moving the pendulim is not enough the escapement wheel seems to not be in the right position and the escapement just goes back and forth so I need to turn it just a little so it can start turning and then it goes again.
I just want to make sure I am not missing anything hanging the weight, the string is going from the spool through the pulley and hooked to the little hook on the other side of the clock.
Thanks! Herb
Just to clarify, are you saying that the escapement doesn't rotate when you manually move the pendulum back and forth?
This would tell you to look for friction in the gear train.
Start by looking for physical defects like blobs or elephant foot, focusing directly where the gears are meshing when the clock stops.
Look from the sides to see if any sideways interference is occurring.
Move each gear in and out to check for end shake. Also notice if the escapement starts spinning again as you touch each gear.
Check that the cord is not binding on itself.
The next steps involve taking the clock apart to double check that every gear spins freely on the arbor and within the frame. These steps are outlined in the assembly guide.
You can try greasing the pinion teeth to see if things improve. Very little grease is needed. It will work into the main gear teeth.
Remove the pallet and let the gears spin until the weight hits the floor. Sometimes this loosens things up.
