Brake Maintenance
Adjusting the Service Brakes
Adjust the service brakes when there is more than 1 in.
(25 mm) of "free travel" of the brake pedal, or when the
brakes do not work effectively. Free travel is the distance
the brake pedal moves before braking resistance is felt.
1. Disengage the locking latch from the brake pedals so
that both pedals work independently of each other.
2. To reduce free travel of the brake pedals, tighten
the brakes:
A. Loosen the front nut on the threaded end of the
brake cable (Figure 79).

B. Tighten the rear nut to move the cable backward
until the brake pedals have 1/2 to 1 in. (13 to
25 mm) of free travel.
C. Tighten the front nuts after the brakes are
adjusted correctly.
Belt Maintenance
Servicing the Alternator Belt
Service Interval: Every 100 hours
Check the condition and tension of the belts (Figure 80)
after every 100 operating hours.
1. Proper tension will allow 3/8 in. (10 mm) deflection
when a force of 10 lb. is applied on the belt midway
between the pulleys.
2. If the deflection is not 3/8 in. (10 mm), loosen
the alternator mounting bolts (Figure 80). Increase
or decrease the alternator belt tension and tighten
the bolts. Check the deflection of the belt again to
ensure that the tension is correct.
