Examination
1. Check the clutch release mechanism and replace worn parts if necessary.
2. Check the release bearing, which should rotate easily, evenly and quietly. The working surface of the bearing, acting on the pressure spring, should be smooth, without cracks, local corrosion or wear. If these defects are present, the release bearing must be replaced. On leading clutch assemblies of the second type, the entire assembly must be replaced.
