Have you ever encountered the problem of oil leakage in Bora s manual half shaft?

Bora Legend Half shaft oil leakage is not normal. Qin Zheng

FAW-Volkswagen. The cause of the oil leakage of the Bora half-shaft is basically caused by poor sealing, which may be an assembly problem. If this happens to a new car, the oil seal can be ruled out.

The possibility of aging, thus identifying it as an assembly problem. The same problem will not occur again after the oil is replaced with a new oil seal.

Causes of oil leakage in half shafts: More than 90% of oil leakage problems are caused by the corrosion and aging of oil seals, because rubber seals lose their plasticizer over time due to the changing temperature of alternating cold and warm.

The seal then shrinks, loses its elasticity, and then hardens, making oil leakage inevitable.

The half shaft of the car often beats very much, and the temperature rises with pressure, the traditional rubber oil seal is difficult to meet, and the manufacturer uses the most low cyanide rubber oil seal, high temperature resistance is not good, easy to age, so the general oil leakage.

If the half-shaft oil leakage is not serious, it basically has no impact, and if the leakage is serious, the oil seal must be replaced, because the leakage is the gearbox.

In general, in order to solve the problem perfectly, the oil seal and the half shaft are replaced together, because the oil leakage is sometimes worn out of the half shaft, and it is useless to change the oil seal, only the half shaft oil seal is replaced together.

This is a quality issue.

According to the data of the car quality network, the oil leakage of the half-shaft oil seal of the 19 Volkswagen Bora car is caused by the poor sealing, if this situation occurs in the new car, the possibility of aging of the oil seal can be ruled out, and it can be identified as an assembly quality problem. The half shaft of the automobile often beats very much, and the temperature rises with the pressure, which is difficult to meet with the traditional rubber oil seal. Moreover, manufacturers use low-cost nitrile rubber oil seals, which cannot withstand high temperatures and are easy to age, so if the leakage is not serious, there is basically no impact.

If the leak is severe, the oil seal should be replaced, as it is the transmission oil that is leaking. If the leakage time is long, it will affect the lubrication of the gearbox and damage the gearbox. Generally, in order to solve the problem perfectly, the oil seal and the half-hare shaft are generally replaced together, because sometimes the oil leakage is caused by the wear of the half-shaft, and it is useless to change the oil seal.

Only the half-shaft oil seals can be replaced together.

The reason for the oil leakage of the FAW-Volkswagen Bora half-shaft is basically the poor sealing, which may be an assembly problem. If this happens in a new car, the possibility of oil seal aging can be ruled out and considered to be an assembly problem. After replacing the oil seal, the same problem will not occur again.

Causes of oil leakage in half shafts: More than 90% of oil leakage problems are old dates caused by the corrosion and aging of oil seals, because over time, under the influence of alternating temperature changes, rubber seals will lose plasticizers, and then seals will shrink, lose elasticity, and then become hard, and oil leakage problems are inevitable. The half shaft of the car often jumps a lot, the temperature rises with the pressure, the traditional rubber oil seal is difficult to meet, the manufacturer uses a very low nitrile rubber oil seal, high temperature resistance.

If the oil leakage of the half-shaft is not serious, it will not affect it at all. If the oil leak is severe, it will be solved by replacing the chamber and removing the oil seal, because the oil leaking is the transmission oil. If it leaks for a long time, it will affect the smoothness of the gearbox and damage the gearbox.

Generally, in order to solve the problem perfectly, the oil seal and the half shaft are usually replaced together, because sometimes the oil leakage will be worn by the half shaft, and it is useless to replace the oil seal. Only the oil seals of the half shaft can be replaced together.

Millions of car purchase subsidies.

Causes and solutions of oil leakage from Bora drive shaft: 1. First, check whether the oil seals at the front end and rear end of the crankshaft are leaking. Oil leakage at the front end of the crankshaft will be caused by the rupture and damage of the oil seal at the front rough end of the crankshaft, aging or the wear of the contact surface between the crankshaft pulley and the oil seal.

The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft. In addition, attention should be paid to whether the rear end of the camshaft oil seal is leaking. The oil seal should be replaced in time if it is aging, broken and leaking.

In addition, it is necessary to check whether there is leakage in each part of the engine lubrication system; 2. If there is oil leakage at the front and rear oil seals, or even organic oil seeping out from the front and rear cylinder head covers, front and rear valve tappet chambers, oil filters, oil pan liners, etc., but no obvious oil leakage can be found, the crankcase ventilation device should be checked, and the crankcase ventilation duct should be cleaned, especially whether the PCV valve is poor due to carbon deposition and gelatinization. If the crankcase is poorly ventilated, it is likely to cause the pressure in the crankcase to rise, resulting in multiple oil seepage and leakage of the rubber stool; 3. If the joints of the oil filter and some oil pipelines are still leaking after being tightened, attention should be paid to checking whether the oil pressure is too high and whether the oil pressure limiting valve is working poorly.

The solution to the oil leakage of the Bora drive shaft is to replace the new oil seal. The transmission shaft has oil leakage, fracture, damage to the lamp phenomenon can be replaced, the oil leakage of the transmission shaft needs to replace the oil seal, if the replacement is not carried out for a long time, the longer the vehicle driving time, the more serious the wear of the parts, will cause a driving safety accident. The phenomenon of the broken propeller shaft is as follows:

1. When the car starts or shifts gears during driving, there is a sound of collision on the transmission shaft, especially when driving at low speed in high-speed gears, the sound is more obvious;

2. There is no abnormal sound of the transmission shaft when the car starts, and the transmission shaft has the sound of hitting the wide rock when the car is driving;

3. There is no abnormal sound of the transmission shaft when the car starts, but there is abnormal sound of the transmission shaft when the car is coasting;

4. The car makes a constant sound during the whole driving process.

The new Bora half-shaft is not insulated, and the oil leakage is caused by poor sealing。If this happens in a new car, the possibility of oil seal aging can be ruled out, and it can be identified as an assembly problem. The same problem will not occur again after the oil is replaced with a new oil seal.

More than 90% of oil leakage problems are caused by the corrosion and aging of oil seals, because over time, rubber seals lose their plasticizer due to the changing temperature of alternating cold and warm.

Solutions to oil spillsIf the oil leakage of the half-shaft is not serious, it will not affect it at all. If the oil leak is severe, it will be solved by replacing the oil seal, because the oil leaking is the transmission fluid. If it leaks for a long time, it will affect the lubrication of the gearbox and damage the gearbox.

Generally, in order to solve the problem perfectly, the oil seal and the half shaft are usually replaced together, because the reputation code is that sometimes the oil leakage will be worn by the half shaft, and it is useless to replace the oil seal. Only the oil seals of the half shaft can be replaced together.
