CLUTCH ADJUSTMENT

Moderate clutch pedal play ranges from 0.79 to 1.18

pedal. If it becomes difficult to disengage the clutch or
pedal play decreases, adjust the length of the clutch
rod. From inside the left side panel, remove the
internal cotter pin and clevis pin to disconnect the
clutch rod. If the clutch is difficult to disengage,
shorten the rod. If there is too little play in the clutch
pedal, lengthen the rod. See Figure 44.
