Is The Clutch Pressure Plate Broken?

    The clutch consists of three sets, namely the clutch pressure plate, the clutch plate, and the release bearing. The three-piece set can be used normally for about 100,000 kilometers, but it is also related to the driving habits of different car owners. If the vehicle is often in a semi-linked state, starting with a big accelerator or high speed and low gear, the service life of the three-piece set will be greatly shortened.

    The clutch pressure plate is broken and can smell a burnt smell. The clutch plate slips, the acceleration is weak, the power is reduced, the starting slips, or the driving is weak. When the engine speed rises, the vehicle speed cannot start.

    If the clutch pressure plate is damaged, the clutch will still slip after engaging, resulting in insufficient power for the car. Therefore, we should always check our clutch pressure plate in the process of daily car use. There are several aspects of the inspection of the clutch pressure plate here:

   (1) Deformation detection of the pressure plate: Put the working surface of the pressure plate on the flat plate, measure the gap between the working surface of the pressure plate and the plate with a feeler gauge, and the flatness of the surface of the pressure plate is not allowed to exceed the limit. There are grooves on the surface of the pressing plate, and the depth of the groove is not allowed to exceed 0.3 mm. The warping deformation of the pressing plate or the groove can be ground on a surface grinder or turned on a lathe. However, the pressure plate with serious deformation or excessive groove depth, or rupture defect should be replaced.

   (2) If the clutch cover is found to be cracked, damaged, or deformed during the maintenance of the clutch cover, replace the clutch cover or pressure plate assembly.

   (3) Maintenance of the diaphragm spring If the diaphragm spring has defects such as broken spring, burns, cracks, etc., the diaphragm spring should basically be replaced. The wear of the end of the diaphragm separation finger can be checked with a vernier caliper. The depth should be less than 0.6 mm and the width should be less than 5 mm, otherwise, the diaphragm spring should be replaced. When the diaphragm is deformed, cover the inner end of the spring separation finger with a professional tool, and then use a feeler gauge to measure the gap between the inner end of the spring and the special tool. The inner ends of the springs should be on the same plane and the gap should not exceed 0.5mm.
