Free travel is too small or subject to excessive load times.

Free travel is too small or subject to excessive load times. Upon request, the general clutch lever clearance between the bearing and the separation of 2.5mm more appropriate to reflect on the clutch pedal free travel for 30 ~ 40mm, free travel is too small or no free travel, will make the separation lever and separation Slewing bearing in a normally engaged state. According to the principle of fatigue damage, bearing work longer, more serious damage; load times by the more, the more easily separated bearing fatigue damage. And the longer working hours, the higher the temperature of the bearing, the easier burning, reduce separation bearing life.
(2) whether the separation was smooth adjustment lever, release fork is deformed, release bearing return spring is good, but also has a great influence on the damage to the separation of the bearing. Separate adjustment is not flat, isolated fork deformation, release bearing spring does not return, will result in the clutch release bearing against the work, so that the state is always in work release bearing, the temperature rising, burn easily release bearing, reducing the separation bearing life.
