The car gearbox is leaking, what should I do?

Sealant is applied to the leakage point, that is, the sludge is cleaned on the surface, and this method does not require dismantling the gearbox structure. In addition, it is not excluded that there may be leakage problems in individual gearboxes, and if there are traces of liquid flowing on the surface of the oil, it is necessary for the owner to go to the shop as soon as possible to check it.

What should I do if the car transmission leaks oil? Of course, it's going to be repaired! If you have the money, it's not impossible to just get a new car.

It's a problem to go to ** repair. If your car is first-hand and relatively new. During the warranty period of the vehicle, it is best for you to choose a 4S shop for maintenance.

Because of the quality of the car itself, the manufacturer has the responsibility and obligation to help you repair it. It might cost a little money, but not a lot.

If you buy a second-hand car or have bought it for a long time, you don't usually repair and maintain it in a 4S shop. Then you can find a relatively reliable car repair shop and carry out repairs. Comparatively speaking, these repair shops, the repair ** will be cheaper.

Solution:1If the screw is loose, tighten the nut. 2.If the oil seal is aged, replace the aged oil seal. 3.If there is an oil leak in the journal, the worn weld should be repaired or replaced.

Hurry up and repair it, it's all there, it's too serious.

Answer; Claim, the gearbox oil leakage is generally a broken pad, and it can be replaced. If there is oil leakage at the oil bottom, the oil pan and the oil bottom fixing screws will be checked first, and the bottom shell will be deformed or the screws will be damaged under normal circumstances; Another scenario is a leak of oil from the side cover gaskets and oil seals. According to the current dealer's after-sales capacity,

There are many points of oil leakage in the gearbox, if it is the gearbox half-shaft oil seal or the front and rear oil seals, this can be replaced separately, if it is the gearbox shell oil leakage, then the gearbox needs to be disassembled, and then re-glued, the problem can be solved.

Mine is the same as yours, the gearbox leaks oil, the first warranty has been found, the 4S shop gave the same detection suggestions as yours, the maintenance method is also dismantling, the engine gearbox is removed and the oil seal is re-smashed, I refused, as long as it is not a large-scale oil leak, it is not in the way, but dismantling once is bound to affect the subsequent value retention rate, I personally do not recommend that.

More than 90% of the causes of oil leakage are caused by the aging of seals (oil seals)! Seals (oil seals) harden over time, that is, they lose their plasticizer over time. This process is exacerbated by the constant alternating operating temperatures of warm and cold.

As a result of this poor process, the seals first begin to shrink, then harden, and finally even break, and oil leaks are inevitable.

Now the more popular oil leakage solution is to add German Mattie DS directly to the oil, under normal driving, the oil leakage problem will disappear naturally in about 14 days, and the car will not be delayed for dismantling and repairing, so as to avoid the waste of time and money caused by dismantling and repair, and it is easier for the owner to solve the oil leakage problem by himself.

The traditional maintenance plan is to dismantle and repair the vehicle, and the man-hour cost is often thousands of yuan, as well as the cost of replacement, and the maintenance time is long. At the same time, due to improper operation and other reasons in the process of dismantling and repairing, the vehicle has many other sequelae. Some oil leaks need to disassemble the engine, so I advise you not to disassemble it easily, the car is not broken, it is repaired!

Traditional solutions can be summarized as time-consuming, labor-intensive, and costly.

More than 90% of the oil leakage is caused by the corrosion and aging of the oil seal. Especially for cars that are more than three years old. Because the rubber seal will lose the plasticizer due to the influence of the temperature change of cold and warm for a long time, the consequence is that the seal shrinks and hardens and loses elasticity, and even breaks seriously (this degree is far from reaching, and oil leakage will be found during maintenance), and the problem of oil leakage is inevitable.

This problem is not recommended for dismantling and repairing, and it can range from hundreds to thousands or even tens of thousands at a time. But it may not solve the problem and hurt the car. It is recommended that the majority of car owners and friends use the method of "solving car oil leakage without dismantling and repairing" to solve car problems without dismantling and repairing.

1.Improved vent cover and inspection hole cover. One of the main causes of oil leakage is that the internal pressure of the gearbox is greater than the external atmospheric pressure.

If the internal and external pressure is balanced, oil leakage can be prevented. Although all reducers have exhaust caps, the exhaust holes are too small and easy to be clogged by pulverized coal and oil, and the cover plate of the inspection holes must be opened every time they are refueled, so that once opened, the possibility of oil leakage will increase, and the original place that does not leak oil will also leak oil.

2.Improved shaft seal structure. The output shaft of the reducer of most equipment such as belt conveyor, screw discharger, impeller coal feeder is a half shaft, which is easy to transform.

Disassemble the reducer, remove the coupling, take out the end cover of the shaft seal of the reducer, process the groove outside the original end cover according to the matching size of the skeleton oil seal, install the skeleton oil seal, and the spring side is facing inward. When reassembling, if the end cap is more than 35mm away from the inner end face of the coupling, a spare oil seal can be installed on the shaft outside the end cap. Once the oil seal fails, the damaged oil seal can be taken out and pushed into the end cap, eliminating the need to disassemble the reducer, disassemble the coupling and other time-consuming and laborious procedures.

3.The new sealing material can be used to plug leaks at the static sealing point of the gearbox.

4.Rub. The static sealing point of the gearbox can generally be treated to achieve no leakage, but the dynamic sealing point still has slight leakage due to the aging of the seal, poor quality, improper assembly, and high surface roughness of the shaft.

Due to the harsh working environment, the coal dust sticks to the shaft and looks oily, so it is necessary to wipe the oil on the shaft after the equipment stops running.

Attachment: Definition method of gearbox oil leakage:

The oil leakage of the old rough gearbox is similar to the engine oil leakage, which is divided into oil leakage and oil leakage, and most of it is oil leakage, not real oil leakage. Oil leakage refers to the oil stains that seep out due to the poor sealing of the internal seal of the gearbox or the aging of the oil seal, which does not affect the normal use of the vehicle. Oil leakage refers to the failure of the transmission oil seal or quality defect causing the transmission oil to drip and leak quickly.

In this case, you must always be vigilant, often observe the transmission oil level, and deal with it in time.

Millions of car purchase subsidies.

Whether the gearbox leakage is repaired or not depends on the situation.

1. Transmission oil leakage is generally divided into two situations: automatic transmission models and manual transmission models.

2. The oil leakage of the gearbox is not very serious, and it can not be repaired, because the gearbox oil is also called gear oil in the manual gearbox, which lubricates the gears in the gearbox, and there is no problem with a lack of a point, which will not affect driving.

3. But if it is an automatic transmission model, the oil of the gearbox will seep out, if it is not powerful, it doesn't matter if it is not good, you can not repair it, this is simple, buy a small barrel of ATF oil, and add a little at any time.

Oil Leakage and Oil Leakage:

Oil Leak: The oil has formed a droplet at the lowest position of the car. Looking at your car from oozing to forming a droplet, it is estimated that it will only be a matter of a few minutes, and the diagnosis of oil leakage is from the perspective of maintenance experts.

Oil Leakage: Due to the aging of the sealing strip or oil seal, a layer of oily dust (not dripping) is formed at the joint site, which is considered oil leakage in the maintenance industry.

If it is engine oil, the maintenance interval is about 5000 to 8000 kilometers to change the oil, which can be used as rehydration. You are the transmission oil, and the replacement interval is at least 40,000 kilometers later. According to the current "oil leakage", it is uncertain how much is left after running to 40,000 kilometers.

If the gearbox oil leak is found in time and properly maintained, it can be repaired. Double-check the place where the oil is leaking. If the oil seal or O-ring on the end cap is damaged, replace it.

If there is oil leakage at the connection of the box, it is too troublesome to disassemble and repair. Clean the oil leak with gasoline. After the gasoline is dry, use sandpaper to reduce oil leakage, mix with AB glue and stick it on the oil leakage until the glue is dry.

The solution to the oil leakage of the gearbox is as follows: 1. If the gearbox leaks, the first step is to determine whether it is oil leakage or oil leakage. 2. The occurrence of some oil leakage is not continuous, as long as it is no longer strictly grinding, ignore it, you can continue to drive for short distances, find a maintenance station to check the gearbox oil leakage fault, if the oil leakage gearbox is very serious, it is necessary to check and deal with it as soon as possible.

3. When the gearbox has obvious shift impact and setback, it is necessary to check the transmission oil as soon as possible, otherwise long-term use is likely to lead to overheating of the transmission oil temperature, and the gearbox gear belt is poorly lubricated. 4. At the same time, frequent high-speed operation or rapid acceleration will also lead to an increase in the oil temperature of the gearbox, increasing the probability of oil leakage in the gearbox.
