the spring and tighten the nut directly below the yoke
(Fig. 55). Turn the nut until the correct measurement is
obtained. Tighten the two nuts together and repeat on
the opposite side of the unit.
4. Turn the nuts clockwise to shorten the spring length and
turn them counterclockwise to lengthen the spring.
