Brake Maintenance

Adjusting the Service Brakes

Adjust the service brakes when there is more than 25 mm
(1 inch) 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. Release 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
Figure 59
1. Brake cable
B. Tighten the rear nut to move the cable backward
until the brake pedals have 13 to 25 mm (1/2 to
1 inch) 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
every 100 operating hours.
1. Proper tension will allow 10 mm (3/8 inch) deflection
when a force of 4.5 kg (10 lb) is applied on the belt
midway between the pulleys.
2. If the deflection is not 10 mm (3/8 inch), loosen the
alternator mounting bolts
Note: 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.
