(1) The damage caused by operating panel press is mainly surface wear, scratch, tear, deformation, strain, deformation, strain, deformation, strain and deformation Pressure plate deformation detection: Place the pressure plate working face on the plate and measure the gap between the pressure plate working face and the plate with a plug. The alignment of the pressure plate surface shall not exceed the limit The depth of grinding groove on the surface of press shall not exceed 0.3 mm. The bending deformation of press or groove can be ground on surface grinder or lathe However, plates with severe deformation, excessive groove depth or rupture defects should be replaced.

(2) Replace the clutch cover or pressure plate assembly if the clutch cover is broken, damaged or deformed when repairing the clutch cover.

(3) Maintenance of diaphragm spring If the diaphragm spring has defects such as broken spring, burning and cracking, etc. ⑤ It is mainly necessary to replace the diaphragm spring Diaphragm separation means that the end wear can be checked with optical scale. The depth should be less than 0.6 mm and the width should be less than 5mm.

Otherwise, the diaphragm spring should be replaced When the diaphragm is deformed, the inner end of the spring finger is closed by a professional instrument. The gap between the inner end of the spring and the special instrument is measured by a measuring ruler The inner end of the spring shall have a clearance of not more than 0.5 mm in the same plane... Otherwise, use the repair tool to adjust the spring breaking cost due to excessive tilt deformation.
