Blade Brake Band Adjustment
After the maximum pulley travel is set, adjust the
working travel of the clutch idler pulley by adjusting
the brake band nut and make the following adjust-
ment as needed:
1. Adjust the blade brake band, using the adjust-
ment nut until pulley travel is approximately
5/8 in. to 3/4 in. (16 mm to 19 mm) from en-
gaged to disengaged.
NOTE:
As blade brake band/drum wears,
pulley travel will increase and it will be neces-
sary to adjust the blade brake band nut to
maintain these dimensions.
