Warning: Clutch lining dust that coats clutch components may contain asbestos, which is hazardous to health. Do not blow off with compressed air or inhale. Do not use gasoline or other non-gasoline based solvents to remove dust. Use brake cleaner or methylated spirits to remove dust into a suitable container. Then wipe clutch components with clean rags and place in a sealed, labeled container.

Examination
3. Rotate the release bearing and check for ease of rotation. Hold the outer race and try to move it lengthwise against the inner race. If play or binding is detected, replace the bearing. When installing a new clutch, the release bearing should be replaced.
Installation
4. Clean and then lightly lubricate the surfaces of the release bearing that contact the release lever. Similarly, lubricate the guide bushing.
5. Slide the bearing into place on the guide sleeve, then rotate it until it snaps into place on the release lever.
