Maintenance of Clutch Bearing is Very Important

The clutch bearing is a relatively important part of the car. If it is not well maintained and malfunctions, it will not only cause economic losses, but also it will be quite troublesome to disassemble and assemble once, and it takes a lot of man-hours.

The clutch bearing is a relatively important part of the car. If it is not well maintained and malfunctions, it will not only cause economic losses, but also it will be quite troublesome to disassemble and assemble once, and it takes a lot of man-hours. Therefore, it is very important to find out the cause of the failure of the clutch bearing.

The clutch release bearing is lubricated with grease. In actual work, repairers tend to ignore the lubrication problem of the release bearing and do not add grease to the release bearing during installation, resulting in a lack of oil in the clutch release bearing. The wear amount of non-lubricated or less-lubricated release bearings is often several to several tens of times that of lubricated release bearings. As the wear increases, the temperature will also increase greatly, which makes it easier to damage the release bearing. Therefore, during the repair process, check the lubrication of the release bearing when installing the clutch, and timely add grease for maintenance.

The damage of the clutch release bearing has a lot to do with the operation, maintenance and adjustment of the driver. The reasons for the damage are rough as follows:

  1. The working temperature is too high to cause overheating

Many drivers often half-depress the clutch when turning or decelerating, and some have their feet on the clutch pedal after shifting gears; some vehicles have too much free stroke adjustment, which makes the clutch disengagement incomplete and in a semi-engaged and semi-released state A large amount of heat generated by dry friction is transferred to the release bearing. The bearing is heated to a certain temperature, and the butter melts or dilutes and flows, which further increases the temperature of the release bearing. When the temperature reaches a certain level, it will burn out.

  1. Wearing due to lack of grease

The clutch release bearing is lubricated with butter. There are two ways to add butter. In actual work, the driver tends to ignore this point, causing the clutch release bearing to run out of oil. In the case of no lubrication or less lubrication, the amount of wear of the release bearing is often several to several tens of times the amount of wear after lubrication. As the wear increases, the temperature will also be greatly increased, so that it is more vulnerable to damage.

  1. The free stroke is too small or the number of loads is too much

According to the requirements, the clearance between the clutch release bearing and the release lever is 2.5mm. The free stroke reflected on the clutch pedal is 30-40mm. If the free stroke is too small or there is no free stroke at all, it will cause the separation lever to interact with each other. The release bearing is in a normally engaged state. According to the principle of fatigue failure, the longer the working time of the bearing, the more serious the damage; the more times the bearing is loaded, the easier it is for the release bearing to produce fatigue damage. Moreover, the longer the working time, the higher the temperature of the bearing, the easier it is to burn, which reduces the service life of the release bearing.
