The clutch may need set or adjusted to the specifications due to worn clutch discs. As clutch discs wear, they will lose material, therefore decrease in thickness, causing the spring deflection to decrease. This procedure will reset the clutch to the correct torque.
Note: An incorrect setting does not indicate incorrect factory setting. This system is subjected to wear during operation.
