(1) Operating temperature is too high lead to overheating. Many drivers in turning or deceleration, often half-pedal clutch, some Guadang rear foot on the clutch pedal also; Some vehicles free travel adjustment is too large, making the clutch is not complete, in a semi-bonding, semi-isolated state, this causing the state of the friction generated between the sliding friction plate and flywheel, a large amount of heat transmitted to the bearings, the bearing is heated to a certain temperature, the melted grease or diluted flow, the temperature of the bearing to further improve the separation, when the temperature reaches a certain degree will burn bad release bearing.
(2) the lack of grease and abrasion. Clutch release bearings with grease lubrication. Repair personnel in practical work release bearing lubrication problem is easy to ignore, and do not release bearing lubrication during installation, causing the clutch release bearing starvation. No lubrication or less the amount of wear of bearings lubricated separate release bearing lubrication is often several times to several times. Wear increases, the temperature will increase greatly, so more damage to the release bearing. So in the repair process, the installation of the clutch release bearing lubrication to check, timely lubrication maintenance.
