Driver/Service Technician Communication

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.
