c. If the clearance is not 3/8" (9.5 mm) loosen the
locking nut from the adjusting nut, and turn the
adjusting nut in or out to obtain the 3/8" (9.5
mm) gap.
d. When the proper gap is reached, hold the adjust¬
ing nut with a wrench and tighten the locking
nut to it firmly.
7. Pulley Brake Adjustment
a. The pulley brake return spring (C, Figure 36)
should be compressed enough so that it mea¬
sures 1-3/8" (34 mm) with the clutch-brake
pedal released (up). If it does not, turn the nut
(D) to obtain the proper measurement.
b. After adjusting the pulley brake return spring,
press the clutch-brake pedal down fully to en¬
gage the brake.
c. While holding the clutch-brake pedal down fully,
measure the length of the spring (A) on the
pulley brake rod. It should be compressed to
1-3/4" (45 mm). If it is not 1-3/4" (45 mm)
loosen the adjusting nut (B) and move it forward
or back until the proper measurement is reached.
Then hold adjusting nut and tighten the locking nut firmly
to it.
