Adjusting the Parking Brake

Check the parking brake for proper adjustment.
1. Disengage the brake lever (lever down).
2. Measure the length of the spring. The measurement
should be 2-3/4 inch (74 mm) between the washers
(Fig. 58).
3. If an adjustment is necessary, loosen the jam nut below
the spring and tighten the nut directly below the yoke
(Fig. 58). Turn the nut until the correct measurement is
obtained. Tighten the two nuts together and repeat on
the opposite side of the unit.
4. Turn the nuts clockwise to shorten the spring length and
turn them counterclockwise to lengthen the spring.
5. Engage the parking brake, lever up.
6. Measure the distance between the trunnion roller and
the collar on the brake rod. The measurement should be
3/16–1/4 inch (5–7 mm) (Fig. 58).
7. If an adjustment is necessary, loosen the jam nut
directly below the yoke. Turn the bottom adjusting nuts
until the correct measurement is obtained (Fig. 58).
Tighten the jam nut at the yoke.

Servicing the Fuses

The electrical system is protected by fuses. It requires no
maintenance; however, if a fuse blows, check the
component/circuit for a malfunction or short.

Alternator F2—20 amp, blade-type
1. Raise the seat to gain access to the fuse holder (Fig. 59).
2. To replace the fuses, pull out on the fuse to remove it
(Fig. 59).
