① The inner end height of the separation lever is not in the same plane.

② The driven disk or pressure disk warps and deforms, and the end circle of the working end face of the flywheel is seriously runout.

③ The thickness of the friction sheet of the driven disk is uneven, oil, scorch, the surface is uneven, the surface is hardened, the rivet head is exposed, the rivet is loose or cut off, and the wave spring sheet is damaged.
