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 you feel
braking resistance.
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 as follows:
A.
Loosen the front nut on the threaded end of
the brake cable

1. Brake cable
B.
Tighten the rear nut to move the cable
rearward 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: After the first 10 hours
Every 100 hours
Proper tension of the belt allows 10 mm (3/8 inch) of
deflection when a force of 44 N∙m (10 ft-lb) is applied
on the belt midway between the pulleys.
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.
