Clutch Adjustment – (Continued)
Clutch Adjustment Bolt
Part # 25321
The clutch spring is held in place by two clutch forks that are connected by the clutch adjustment bolt.
The clutch adjusting bolt has two nuts set together that hold the clutch forks and spring in position once it
has been adjusted to the proper tension. The inner nut is for adjusting the tension of the spring and the
outer jam nut, when tightened against the inner nut, secures the desired tension of the spring.
Adjusting the Clutch Spring Tension
Step 1
Disengage
the clutch. This will allow the drive sprocket to move slightly to the right and to the left on the
drive shaft.
Step 2
Use one 1/2” wrench to hold the inner nut and the second 1/2” wrench to loosen the outer jam nut. Once
the outer jam nut is loosened, the inner nut can be turned clockwise to; compress the clutch spring,
widening the gap between the clutch pad and sprocket but decreasing the tension on the clutch, or
counter clockwise to; lessen the tension on the spring, decreasing the gap between the clutch pad and
sprocket and increase the tension on the clutch.
