is encased in the flywheel hub.
2. Check whether there is abrasion on the diaphragm spring.
Check the abrasion depth and width of diaphragm spring with
calipers.
Limit value: Max depth: 0.6mm
Max width: 5mm
If the abrasion depth or width of the diaphragm spring exceeds
the limit value, change the diaphragm spring .
3. Check the separation bearing
Exert force in radial direction by hand to rotate the bearing.
If it cannot be rotated or if the resistance is too large, change
the separation bearing.
Remark:
Remark: as this bearing is lubricated permanently, it doesnít
need to be cleaned or lubricated.
