gap between brake pad and belts, follow
these steps:
a. To increase brake pad gap,
loosen idler adjustment nut, and
move idler away from belt.
Position idler to achieve a 1/16 in.
(1.6 mm) minimum brake pad gap
and a 1/2 in. (12.7 mm) minimum
gap between the plastic roller and
the frame.
b. Check the clutch cable spring
extension and adjust as
necessary to achieve a 1/2 – 9/16
in. (12.7 – 14.3 mm) spring
extension.
c. If the cable needed adjustment,
recheck gaps described in step

until brake clearance, roller gap
and spring extension are within
specified ranges.
IMPORTANT: If adjustments cannot be
brought into specified ranges see your Dealer
for repairs.
