Removing the ·Balance
Wheel
Two "V-conic" studs ore used as
bearings for the bo lance staff on the
TIMEX Model 25 movement. The
bearing on the dial plate is mounted
in a screw so that fine endshake ad-
justment is possible.
Removal
of
the balance wheel assem-
bly should be carried out in the fol-
lowing
manner:
a) Remove the hairspring wedge pin,
being careful not to distort either
the pin or the hairspring.
b) Rotate the balance wheel slowly
until the hairspring toil is free of
the hairspring wedge pin brocket
and the regulator .
c) Loosen
the bo lance screw ossemb ly
(counter-clockwise direction) us-
ing a su itabl e screw driver, until
the end of the balance staff is
free of the "V-conic" bearing .
During the loosening of the screw,
only minimum downward pressure
should be applied with the screw
driver,
as excessive downward
pressure could seriously damage
the balance staff points.
d) Carefully remove the balance as-
sembly.
