Step 2 - 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 engaged
to disengaged.
NOTE:
As blade brake band/drum wears, pul-
ley travel will increase and it will be necessary
to adjust the blade brake band nut to maintain
these dimensions.
