When removing the pallet lever and the escape wheel, the
first operation is to unscrew the solid pillar screw and the tubular
pillar screw. Then remove the tubular pillar. It is also impor
tant to loosen (about Ys turn) the opposite solid pillar screw.
(By doing this, there is less chance of distorting the back frame
during parts removal.) The winding stem must be left in the
movement. This is important because it holds the winding bridge
from falling out when spreading frames. When spreading back
frame from front frame, the thumbnail is inserted between the
back frame and solid pillar. The middle finger rests on the back
frame and pressure is applied, thereby raising the frame. The
pallet lever and escape wheel staff are released from the location
holes. Before changing the pallet lever and escape wheel, it is
recommended that the balance wheel is also removed.
