How to repair the oil leakage after the crankshaft, the oil leakage in the front of the crankshaft,

Generally, when a similar situation is found in driving, stop and check in time, place a warning triangle, turn on the double flash, remind passing vehicles to pay attention, and find that the oil leakage of the automobile crankshaft oil seal is very serious, it is necessary to immediately inject part of the automobile oil into the crankcase, and then quickly drive the car to the nearest maintenance station, after arriving at the maintenance place of the car, if there are auto parts that can be replaced, it is necessary to replace the automobile crankshaft oil seal in time Hope to get you.

The rear oil seal of the engine crankshaft is generally composed of asbestos packing, oil slingering disc and oil return thread structure. Although asbestos packing is low in cost and easy to disassemble and assemble, it also has disadvantages such as unstable performance and inelasticity.

It is difficult to grasp the tightness of asbestos packing in contact with the surface of the crankshaft journal, and after a period of operation, the contact gap will be too large due to wear and deformation, resulting in oil leakage.

The reasons for sealing oil leakage are as follows:

1. The parallelism of the rear oil seal pressing surface and the rear oil seal seat installation surface can not meet the technical requirements, after the engine is used for a period of time, the rear oil seal lip is deformed due to uneven force, resulting in oil seal damage and oil leakage.

2. In the process of press-fitting the crankshaft oil seal, the engine oil is used to replace the relatively higher non-petroleum-based lubricant, which causes the engine to loosen or even fall off after a period of use.

3. If the engine is used for too long, the rear oil seal will naturally age, and cracks will occur at the lip, resulting in oil leakage.

1.More than 90% of the causes of engine 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.

2.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.

3.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.

4.It is recommended that 3-5 year old cars be added to Marty DS in advance to prevent oil leakage.

Danger Danger You have to change the oil seal as soon as possible, otherwise you will have to overhaul it carelessly, if the oil is thrown too quickly, it is easy to burn the tile, and the cylinder liner and ring are seriously worn.

Oil leakage from the rear oil seal of the crankshaft of the car engine, possible causes:

1. The crankshaft oil seal does not use non-petroleum-based lubricants in the press-fitting process, resulting in loosening or even falling off the oil seal after the engine is used for a period of time (for example, some engine manufacturers use engine oil to replace the relatively expensive non-petroleum-based lubricant in order to reduce manufacturing costs).

2. The parallelism of the rear oil seal pressing surface for the installation surface of the rear oil seal seat does not meet the technical requirements of the assembly drawings, which makes the rear oil seal lip unevenly deformed, and the oil seal lip is deformed after the engine is used for a period of time and even the entire oil seal is distorted, resulting in oil seal damage and oil leakage.

3. The engine has a long service life, and cracks occur at the lip of the natural aging of the rear oil seal, resulting in oil leakage.

Reason 1 and 2 are both manufacturer problems, after the problem directly to the manufacturer to ask for maintenance, if the service life is long, then you need to replace the engine in time.

If you find that the oil leakage of the rear oil seal of the crankshaft is very serious, you should immediately inject some oil into the crankcase and quickly drive the car to the nearest repair station. After arriving at the maintenance place of the car, if there are auto parts that can be replaced, it is necessary to replace the oil seal of the rear crankshaft of the car in time. But when there is no spare object for the car, then you can remove the last crankshaft main bearing cover, carefully remove the graphite asbestos strip from the crankshaft main bearing cover, use the asbestos wire coated with a layer of butter to pad it in the oil seal groove, and then press the removed graphite asbestos strip on the asbestos wire according to the original appearance, and can be used for a short time after completion.

Generally speaking, the gear oil of the car will have an obvious smell, while the engine oil of the car has no obvious smell, if the inspection determines that the leakage is the car engine.

, then it can be determined that the leakage is the crankshaft of the car.

The rear oil seal is up. If the oil spill is severe, we can:

1. If the owner has auto parts that can be replaced, it is necessary to replace the crankshaft oil seal in time, but if there is no spare object of the car, then we will deal with it like this. Remove the last crankshaft main bearing cover, carefully remove the graphite asbestos strip from the crankshaft main bearing cover, use the asbestos wire coated with a layer of butter to pad it in the oil seal groove, and then press the graphite asbestos strip on the asbestos wire according to the original appearance, and can be used for a short time after completion, and then drive to the repair shop for maintenance.

2. Immediately inject some car oil into the crankcase, and then quickly drive the car to the nearest maintenance station for maintenance. Hope, thank you!

The rear crankshaft oil seal of the engine is leaking, then the engine should be replaced, and the oil seal of the crankshaft should be replaced with a new oil seal, so that he will not leak.

The oil seal of the engine cannot be repaired and maintained, and it can only be replaced with a new oil seal.

The oil seal is made of rubber products in the second shift, and after a long time, it is easy to age under the soaking of engine oil, and so on, so in case of aging, he will leak oil, and he must replace the new oil seal of the engine.

In general, cars are prone to breakdown after a long journey. However, when there is a problem with the vehicle, there are some signs. If you feel that the vehicle is abnormal, the rider should first be calm, do not panic, choose a suitable parking place, and check the cause of the fault after parking.

Intuitive diagnosis methods are usually adopted, that is, under the condition of not having machine detection, through sight, hand touch, nose smell, ear hearing and other methods to check the working condition of the car itself. For example, according to the oil consumption, gas and liquid leakage, abnormal noise of various parts, as well as the smell and appearance of the car and other phenomena, analysis and judgment, so as to determine the cause of the failure, and then accurately determine the location of the failure.

Use soap and cloth strips to plug leaks.

Tubing breakage: When the tubing is broken, you can find a rubber or plastic pipe that is suitable for the diameter of the tubing. If the socket is not tight enough, the two ends should be tied with iron wire to prevent oil leakage.

Oil leakage from tubing joints:

Cotton yarn can be wound around the lower edge of the horn, and then the tubing nut and the tubing joint can be tightened; Bubble gum or maltose can also be chewed into a paste, coated on the seat of the tubing nut, and sealed after it dries and sets.

Oil and water leakage: According to the size of the sand hole, the fuse of the corresponding specification can be selected, and the hand hammer can be gently smashed into the sand hole to eliminate oil and water leakage.

If the oil seal after the crankshaft of the engine leaks, it is necessary to replace the new oil seal after the crankshaft in time to avoid serious oil leakage and serious mechanical accidents such as the engine holding tile sticking to the cylinder. Replacement method, disassemble the gearbox, disassemble the clutch pressure plate, remove the damaged old curved rear oil seal, and replace the new oil seal.

Hello! Oil seal leakage so it is easy to lack oil, of course, it may be that the sealing ring is damaged, it is better to replace the sealing ring, if the crankshaft is broken, then the project is very large.

The oil seal leakage can only be replaced, which is a bit technically difficult, and the new oil seal needs to be loaded once, otherwise the probability of oil leakage again is very high.

Only a new one can be replaced

If the front and rear oil seals are leaking, pay attention to the following aspects: 1The runout of the oil seal hole and the crankshaft can not exceed, that is, the coaxiality between the oil seal hole and the crankshaft) 2.

Buy a good oil seal (PTFE oil seal with good sealing, high temperature resistance and high linear speed) 3Now there is a spiral line at the oil seal seal, which is divided into left-handed and right-handed, and cannot be reversed 4When installing the oil seal (generally pay attention to the installation of the oil seal after the installation of the fetus), it is best to use the fetal tool, otherwise it is easy to cause damage to the oil seal and leakage 5

If the amount of air channeling at the piston ring is large, the gas temperature in the crankcase rises, which is easy to cause the aging of the oil seal.

Summary. Hello, Happy New Year, dear, the car master for your service, attentive, careful, attentive to answer your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this answer helpful.

Hello, the oil seal of the rear crankshaft of the engine is leaking, and the relevant treatment methods are as follows.

First, depending on the severity of the oil leak, if it is a slight leakage, then it is okay not to repair it in a short period of time.

Second, if the leakage is more serious, this can only be replaced by disassembling the gearbox to replace the crankshaft rear oil seal.

Third, if the vehicle is still within the warranty period, you can go to the 4S shop for free maintenance.

What should I do if the engine rear crankshaft oil seal leaks?

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, happy new year, dear, the car master for your service, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this answer helpful. Happy Chinese New Year, the Year of the Tiger Hello, engine crankshaft oil seal leakage, the relevant treatment methods are as follows: first, this specific look at the severity of the oil leakage, if it is a slight leakage, then this celery is not repaired within a short period of time is also the first to open the second, if the leakage is more serious, this can only disassemble the gearbox to replace the crankshaft after the oil seal third, if the vehicle is still within the warranty period, you can go to the 4S shop for free maintenance.

How long does the crankshaft oil seal leak and how to solve it. He also collected information on the Internet about how long the crankshaft oil seal leaked and what to do. Let me share it with you.

1.If you encounter a similar situation while driving, stop and check in time, erect a warning sign, and turn on double flashes to remind passing vehicles. If you find that the crankshaft oil seal leakage is very serious, you should inject some car oil into the crankcase and quickly drive the car to the nearest repair station.

When you arrive at the car repair site, if there are replaceable auto parts, you should replace the crankshaft oil seal in time.

2.Attachment: Oil seal leakage front oil start reason:

3.The parallelism between the press-fitting surface of the oil seal and the mounting surface of the rear oil seal seat met the technical requirements, but it was not checked at that time. After long-term use of the burial and dismantling machine, the rear oil seal lip is deformed by the force of silver liquid, resulting in oil seal damage and oil leakage, which is the most common oil leakage.

4.After long-term use of the engine, the oil seal will naturally age, and the lip will crack, resulting in oil leakage, which is also the normal aging phenomenon of the crankshaft oil seal.

I hope it helps you through this article, and this is the end of the article.

If the crankshaft oil seal leaks, it must be repaired in time to a 4S shop or a professional auto repair shop, otherwise the engine may be seriously damaged.

The most direct impact of oil leakage in the rear crankshaft is that fuel consumption is aggravated and the amount of oil is reduced, which will affect the lubrication effect of the engine, thereby aggravating engine wear and reducing engine life.

The oil leakage of the rear crankshaft oil seal can be roughly divided into three reasons: edge oil leakage, peripheral oil leakage and oil leakage caused by non-quality reasons.

The common causes of oil leakage at the cutting edge are as follows:1The cutting edge of the oil seal is worn or eccentric; 2.Aging of the cutting edge of the oil seal; 3.The oil seal spring falls off; The oil seal is in the wrong direction; 4.The eccentricity of the shaft is severe, etc.

The common causes of surrounding oil leaks are as follows:1. deformation of oil seals; 2.Loose oil seal; 3.The oil seal is tilted; 4.Scratch the perimeter of the oil seal; 5.The appearance and size of the oil seal are abnormal, etc.

Oil spills caused by non-quality reasons may be caused by:1. A foreign body is stuck in the lips; 2.Excessive pressure in the crankcase system; 3.Abnormally high temperatures cause the lips to harden, etc.

Since you can't see the actual car, you can't make an accurate judgment. In reality, it is recommended to go to a 4S shop or a professional auto repair shop in time, and let the maintenance personnel check it first to see what the problem is. We can only remedy it if we determine what the problem is.

If the crankshaft rear oil seal leaks, you must go to a 4S shop or a professional auto repair shop for repair in time, otherwise it is likely to cause serious damage to the engine. The most direct impact of oil leakage after crankshaft oil seal is that the oil consumption is intensified and the amount of oil is reduced, which will have an impact on the lubrication effect of the engine, thereby aggravating the wear of the engine and reducing the life of the engine.

Oil leakage from the rear oil seal of the crankshaft can be roughly divided into three reasons: oil leakage at the cutting edge, oil leakage at the periphery, and oil leakage caused by non-quality reasons.

The common causes of oil leakage at the cutting edge are: 1. The cutting edge of the oil seal is worn or eccentricly worn; 2. The edge of the oil seal is aging; 3. The oil seal spring falls off; The oil seal is in the wrong direction; 4. The eccentricity of the shaft is serious.

The common causes of oil leakage in the periphery are as follows: 1. Deformation of the oil seal; 2. The oil seal is loose; 3. The oil seal is tilted; 4. Scratches on the periphery of the oil seal; 5. The appearance and size of the oil seal are abnormal.

Oil leakage caused by non-quality reasons may be due to: 1. Foreign body stuck in the lip; 2. The pressure of the crankcase system is too large; 3. Abnormal high temperature leads to lip hardening, etc.

Since you can't see the actual car, you can't make an accurate judgment.

In reality, it is recommended to go to a 4S shop or a professional auto repair shop in time to let the maintenance personnel check it first to see what the problem is.

Only by determining what the problem is, can we guess the symptomatic repair suspicion.
