3. If an adjustment is necessary, do the following:

A. Loosen the jam nut below the spring and

tighten the nut directly below the yoke
(Figure 48).

B. Turn the nut until you obtain the correct

measurement.

C. Tighten the 2 nuts together and repeat on

the opposite side of the machine.

4. Turn the nuts clockwise to shorten the spring

length; counterclockwise to lengthen the
spring.

5. Engage the parking brake, with the lever up.
6. Measure the distance between the trunnion

roller and the collar on the brake rod. The
measurement should be 3/16 to 1/4 inch (5
to 7 mm) (Figure 48).

7. If an adjustment is necessary, do the following:

A. Loosen the jam nut directly below the yoke.
