The pressure between the clutch plate and the driven wheel and the inner and outer pressure plates is not enough, so that the clutch plate is not pressed tightly and causes slipping. If the gap adjustment is not good, check whether the surface of the middle pressure plate and the thrust plate is smooth and whether there is any damage. Their contact surface should reach more than 80%, so that the two clutch plates can be in normal contact and there will be no slippage during operation. Otherwise, it is necessary to consider replacing parts such as the middle pressure plate or the thrust plate to avoid burning out the clutch plates and other parts. Deformation damage.
Improper assembly can also easily lead to the contact surface of the clutch plate and other components not meeting the requirements of more than 80%. At this time, the clutch plate will also be worn off or broken. Therefore, it is required to carefully check the flatness of each component during assembly, and to observe whether it is concentric during trial operation, so as to avoid the wear of the middle pressure plate and the inner gear ring.
