How a Clock Movement Wears.
This Hermle Clock Movement is made up of two brass plates with 3 springs and 15 gears between them. Each gear shaft has two pivots at either end that ride in a hole in each of the plates. As the mechanism runs, the pressure from the spring turns the first gear in one direction, that gear turns the next gear in the opposite direction, and so on. Which ever direction the pressure presses the gear to run, the pivot holes in the plates will wear in that direction. The more the holes wear, the more the gears drag as they move out of alignment, and the more power the movement needs to continue running. Eventually the movement wears to the point that the spring cannot supply enough power to run the clock. At this point the movement will need to be rebuilt.
How the Clock Movement is Rebuilt:
First, the clock movement is completely disassembled and ran through the cleaner. Next, all the worn pivot holes are realigned and then drilled out to the proper size of the bushing it is to receive. The bushings are then pressed into the holes and touched up with a bushing reamer, as needed, to provide adequate clearance for the pivots. (I use only high quality KWM bronze bushings) The springs are stretched while being scrubbed clean, and new spring oil applied. (Any springs that
do not pass inspection will be replace with another good used spring) The movement is then oiled, reassembled, and thoroughly tested.
