Drivers should report erratic clutch operation as soon as possible. This allows service technicians to make the necessary inspection, internal clutch adjustment, linkage adjustments, and lubrication checks before a total clutch failure occurs.
The importance of free pedal cannot be overemphasized. This is the free play travel in the clutch pedal in the cab. A free pedal of 1½ to 2 inches is usually specified. Free pedal is directly related to free travel at the release fork. Free pedal should be a checklist component of the daily driver report form. Changes in free pedal measurement are an indicator to the service technician that problems may exist with internal clutch components, so make a habit of noting it whenever you operate a truck.
