CLUTCH-BRAKE PEDAL ADJUSTMENT
To adjust the angle of the clutch-brake pedal, remove
the cotter pin and washer on the clutch rod and turn
the clutch rod in or out of the ferrule to obtain the
most comfortable angle of the pedal when the pedal
is released. Replace the washer and cotter pin. See
figure 30.
The brake adjustment is made by using a Vi" deep well
socket and turning the adjusting nut clockwise through
the opening in the back panel. This reduces the dis¬
tance between the brake band and the drum. See fig¬
ure 29.
CAUTION
If the spring tension idler goes below
the height of the engine pulley when
the clutch-brake pedal is depressed it
will cause excessive belt wear and the
brake should be adjusted. See figure
30.
