Adjust the length of the clutch link to achieve a bolt
head clearance of 1/4 in. to 5/16 in. (6.35 mm to

remove ball joint from clutch arm, shorten the clutch
link to increase this measurement or lengthen the
clutch link to decrease this measurement. If adjust-

lems with pulley wear or belt misalignment.
