What Are the Symptoms of a Faulty Clutch Pressure Plate?

[LeSerenity]

The symptoms of a faulty clutch pressure plate are as follows: 1. Wear of the diaphragm spring. When part of the diaphragm spring is worn, the friction surfaces do not act uniformly during engagement. The friction surface area controlled by the severely worn spring segment will press against the clutch disc first, resulting in insufficient friction area and causing jerking during take-off. If the diaphragm spring is completely worn, the problem becomes severe, leading to clutch failure and inability to disengage. 2. Wear and looseness of the diaphragm spring support ring. The diaphragm spring support ring is a wire-like component pressed against the diaphragm spring, acting as the fulcrum of a lever. If worn, the fulcrum will shift, causing the clutch travel to lengthen in mild cases, or incomplete disengagement or inability to disengage in severe cases. 3. Loosening of the support ring rivets. The support ring rivets are used to secure the support ring. If loosened, it effectively disrupts the fulcrum of the lever system, also resulting in incomplete clutch disengagement or inability to disengage.
