Taking the windvane tower apart
The turret is held in position by friction of the
course-adjusting disk around the perimeter of the
turret. Loosening the ¼ in. bolt in the edge of the
disk allows to pull up the turret and connecting rod.
When re-assembling, make sure the turret is
pushed down all the way, as the precise length of
the connecting rod in relation to the total length of
the tower is critical to maintain the servo-pendulum
in the vertical position when the vane is also vertical.
If it is not, and the crank at the aft end of the
horizontal axle is not bent out of shape, the length of
the connecting rod is re-adjusted by loosening the
lock nut at its base and rotating it from the top.
