The correct treatment of the oil leakage of the semi-axle oil seal! Semi-axle oil seal leakage This is a situation that we often encounter when we use a car. For a novice driver who does not know the car, if it is a half-shaft oil seal, it is quite annoying. It is completely unclear how to deal with it. Today, Xiaobian will tell you the reason and correct treatment of the oil leakage of the semi-axle oil seal.

Half shaft oil seal leakage reason

Many friends know that the half-shaft oil seal is very harmful, which may cause the amount of lubricant in the drive axle to decrease, which will affect the normal lubrication and increase the wear and tear of the machine parts, causing damage; flowing into the brake drum, causing poor braking, endangering safe driving. Or the lubricating oil flows into the wheel reducer, causing the oil level of the wheel reducer to rise and damaging the oil seal. Therefore, the oil leakage of the half shaft oil seal can not be ignored. Let us look at the cause of the oil leakage of the half shaft oil seal.

1. There is too much oil in the drive axle reducer, and the oil level exceeds the normal height.

2. The sealing effect caused by the deterioration of the oil seal deteriorates.

3. There is a problem with the installation of the oil seal, there is a gap.

4. The drive axle reducer vent is blocked. When driving, the oil temperature rises, the pressure rises, and the oil is squeezed out, causing damage to the oil seal.

5. The quality of the semi-axle oil seal is not good, the size does not match, the oil seal and the semi-axle sleeve are too loose.

6. The hub bearing is loose, the reducer bearing is loose, and the half shaft is shaken up and down.

7. The seal caused by the wear of the semi-axle journal is not strict.

Semi-shaft oil seal leakage solution

1. When changing oil every time, it should be the same as the oil level.

2. Remove the reducer vent cleaning for each maintenance.

3. Choose a suitable and quality half shaft oil seal.

4. The main oil seal is installed correctly when installing the oil seal.

5. For oil seals that may age, they need to be replaced in time.

6. Check the tightness of the hub bearing during secondary maintenance, and make sure that it is not loose.
