The correct way to deal with the oil leakage of the half shaft oil seal

The correct way to deal with the oil leakage of the half-shaft oil sealHalf-shaft oil seal leakage is a situation that we usually encounter with the car, for novice drivers who don't know much about cars, if there is a half-shaft oil seal leakage it is quite annoying, and it is not clear how to deal with it at all. Today, Xiaochi will tell you the reasons for the oil leakage of the half-shaft oil seal and the correct way to deal with it.

Reasons for oil leakage of half-shaft oil seals:

Many friends know that the half-shaft oil seal is very harmful, which may lead to a decrease in the amount of lubricating oil in the drive axle, thereby affecting the normal lubrication, aggravating the wear and tear of the parts and causing damage; flow into the brake drum, causing poor braking and endangering safe driving; Or the lubricating oil flows into the wheel reducer, causing the oil level of the wheel reducer to rise and flush out the oil.

Envelope. Therefore, the oil leakage of the half-shaft oil seal cannot be ignored, so let's take a look at the reasons for the oil leakage of the half-shaft oil seal.

2.The sealing effect of the oil seal deteriorates and deteriorates.

3.There was a problem with the installation of the oil seal, and there were gaps.

4.The vent of the drive axle reducer is blocked, and when driving, the oil temperature rises, the pressure rises, and the oil is squeezed out, resulting in damage to the oil seal.

5.The quality of the half-shaft oil seal is not good, the size does not match, and the oil seal and half-shaft sleeve are installed too loosely.

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

7.Poor sealing due to wear of the half-shaft journal.

Solution to oil leakage from half shaft oil seal:

1.Every time you change the oil, it should be the same as the oil level.

2.Disassemble the vent of the reducer for cleaning every time it is maintained.

3.Choose the right half-shaft oil seal with good quality.

4.When installing the oil seal, the main oil seal is installed in the correct way.

5.Oil seals that may deteriorate need to be replaced in time.

6.During the second level of maintenance, it is necessary to check the tightness of the hub bearing to confirm that there is no loosening.

The treatment of oil leakage of half-shaft oil seal, the oil seal is a hard rubber state of the material, once the oil leakage is caused by the deformation, damage or aging of the oil seal, it cannot be repaired, and the oil seal can only be replaced with a new one.

The correct way to deal with the oil leakage of the half-shaft oil seal is to replace the oil seal.

If the half-shaft oil seal is damaged, it should be replaced in time. The main reason for the non-replacement is that there are problems with the installation process and the quality of the half-shaft oil seals in some repair shops. Due to these two problems, many riders replace the oil seal, the gear oil on the front and rear axles of the gearbox appears to be more and more permeable, and many riders are quite annoyed about the oil seal leakage.

Therefore, many people think that the oil leakage after replacement is more serious, and it is better not to replace it.

Notes:

The half-shaft oil seal should be repaired for oil leakage, and the oil seal can prevent oil penetration and oil leakage. If it is not treated, it will accelerate the loss of gear oil in the front and rear axles of the gearbox, and over time, it will aggravate the wear of the gears and parts, resulting in damage. Whether it is a half-shaft oil seal or other oil seals, as long as the oil leaks, it must be repaired, otherwise the oil will only leak more and more.

For new cars, most of the oil seal leakage is due to installation problems, and the oil seal is not tightly matched, which will cause oil leakage. At this point, you can drive the car to the 4S shop and let them reinstall it.

For older cars. Oil leakage of half-shaft oil seals is mostly caused by corrosion and aging of oil seals. And over time, the rubber parts on the car will harden, shrink, and thus lose their elasticity, and if such a situation occurs, then oil leakage is inevitable.

Solutions to oil leakage from half-shaft oil seals:1Every time you change the oil, it should be the same as the oil level.

2.Disassemble the vent of the reducer for cleaning every time it is maintained. 3.

Choose the right half-shaft oil seal with good quality. 4.When installing the oil seal, the main oil seal is installed in the correct way.

5.Oil seals that may deteriorate need to be replaced in time.

In essence, the damage of the half-shaft oil seal is to be replaced in time, and the statement that it is not replaced is mainly because of the installation process of some repair shops and the quality of the half-shaft oil seal.

Due to these two problems, many car owners replace the oil seal, the gear oil on the front and rear axles of the gearbox appears to be more and more penetrated, and many riders are quite annoyed about the oil seal leakage. Therefore, many people think that the oil leakage after replacement is more serious, and it is better not to replace it.

Half shaft oil seal oil leakage, this situation is normal, mine also has a little bit, but it has no effect, I have been driving for a few years, it is still the same.

1.Half shaft oil seal.

Is there always oil leakage, what are the serious consequences? Seriously, the oil seal is seriously worn, and the installation is not in place; Gearbox.

too much oil; The inner cage is severely worn or deformed. The correct way to deal with the oil leakage of the half-shaft oil sealOil leakage from half shaft oil seals is a situation that we often encounter when using a car.

For novice drivers who don't know much about cars, the situation of oil leakage in the half-shaft oil seal is still quite annoying, and it is not clear how to deal with it at all.

2.The cause of oil leakage in the half-shaft oil seal. Fault Description:

During maintenance, it was found that the half-shaft oil seal was leaking. In fact, oil leakage of half-shaft oil seals is quite common, mainly for three reasons: the oil seals are seriously worn and not installed in place; too much transmission oil; The inner cage is severely worn or deformed.

Cause: The oil seal is badly worn and installed incorrectly. The maintenance technician uses a lift to lift the trolley to detect whether the half-shaft oil pat code seal is aging and cracking, and whether the installation is in place.

Solution: The half-shaft oil seal is aging and cracking, or the installation is not in place, it is recommended to replace it in time. In terms of cost, you can go to the 4S store for free during the warranty period**; If the warranty expires, the cost of the 4S shop is about 300-500 yuan, and the ** of the repair shop is about 300 yuan.

3.If the transmission oil is added too much, the gas generated by the increase in oil temperature cannot be discharged, and the internal parts of the transmission run at high speed, which will cause the transmission oil circulation to be poor. What should I do if Bora's half-shaft oil seal leaks? Solution: Drain the excess transmission.

oil, and return the transmission oil to normal levels. Cause: Severe wear or deformation of the inner cage. The maintenance technician lifts the vehicle with a lift to check whether the surface of the inner cage is smooth and deformed. Solution: Remove the tires and support arms, remove the half shaft, and replace the inner cage directly.

4.The technician had already inspected the vehicle in this case, which was leaking due to severe wear and tear on the half-shaft seal. For details, see Solutions.

In addition, we recommend that car owners maintain their vehicles on time and check their condition regularly. If you find a problem, it's best to fix it as soon as possible. Half a bend shaft oil seal always leaks oil, what are the serious consequences?

Half shaft oil seal leakage is lubricating oil or grease.

1. The variety of oil leaking from the half-shaft oil seal: the oil seal is mainly to prevent the leakage or leakage of lubricating oil or grease. The half-shaft oil seal is to prevent the leakage or leakage of lubricating oil or grease in the half-shaft.

2. Half-shaft oil seal leakage: The half-shaft oil seal is in the lower part of the chassis, and the half-shaft oil seal is used to close and divide the two parts of the drive axle and the wheel side reducer. The half-shaft is used to transmit the output torque of the differential half-shaft gear to the drive wheel or wheel side reducer.

The oil leakage of the half-shaft oil seal will reduce the amount of lubricating oil in the drive axle, affect the normal lubrication, and aggravate the wear of the parts and lead to early damage.

The half-shaft oil seal leaks, and the lubricating oil flows into the wheel reducer, causing the oil level of the wheel reducer to rise, breaking the oil seal, and flowing into the brake drum, causing poor braking and endangering safe driving.

The solution to the oil leakage of the half-shaft oil seal is: when changing the oil, it should be the same as the oil plane, and the reducer should be disassembled to clean the vent during maintenance; Choose the right half-shaft oil seal with good quality. Install the oil seal correctly and replace the aging oil seal in time; Check the hub bearing for looseness. The causes of oil leakage in the half-shaft oil seal are:

Excessive refueling in the drive axle reducer and the oil level exceeds the normal height; The sealing effect of the oil seal deteriorates and deteriorates. The oil seal has a gap to block the pie; The ventilation hole of the drive axle reducer is blocked; The quality of the half-shaft oil seal is not good, the oil seal and the half-shaft simple change bushing are installed too loosely, the hub bearing is loose, and the reducer bearing is loose; Poor sealing due to wear of the half-shaft journal.
