Under normal circumstances, it is impossible to install the clutch plate reversely. Some can be reversed. The anti-clutch cannot be stepped on, or the pedal cannot be decoupled, or the gear will not go when it is always disconnected and geared. It cannot be used if it is installed backwards. One side has a long gear groove, and the other side is a short gear groove. The joint surface of the output gear of the transmission is very small. It is easy to damage the gear groove of the grinding plate of the intermediate pressure plate, and the clutch cannot be separated.
