Ethereal gearbox 1500 rpm abnormal sound

Are you the CVT one? If so, it is generally the abnormal sound of the input shaft, output shaft or pressure cylinder, and you should listen to which part is ringing.

Fumei first tested and completed the maintenance plan, and before dismantling the car, it must be accurate, and if you don't agree, you won't charge a penny; Agree to repair before disassembling the gearbox, after disassembling the new Fumei found that even if the damage is serious, it will not increase the price even if it loses money. I think it's good, there are branches in various places, and major insurance companies have designated maintenance units; Online or ** ask, can give you a detection of transmission problems.

The reasons for the noise in the gear are improper operation, clutch failure, sprocket wear, and chain looseness.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to seep into Chang to avoid unnecessary disassembly, first of all, we must distinguish between normal sound and abnormal sound. The normal vibration sound of each cluster system component (such as the noise on the engine surface), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of damage to the grinding belt of the machine is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal driving of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is abnormal sound of wear.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc.

It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.

Ethereal ( Check price |.)The abnormal sound of the gearbox may be caused by the wear and damage of the bearing, the wear and tear of the transmission components or the low precision of the parts selected when replacement, the poor lubrication caused by insufficient lubricating oil or too high a pump, and the loose bolts of the gearbox shell (end cover).

2. If there is an abnormal sound in neutral and the abnormal noise disappears when you step on the clutch, it may be that there is a problem with the clutch, you can lift the gearbox and check the clutch.

3. If there is an abnormal sound in all gears, it is generally the bearing sound behind the output shaft of the transmission, which should be disassembled and the bearing should be checked.

4. If the abnormal sound disappears when the direct gear is hooked, and there is abnormal noise in other gears, it means that the front bearing of the second shaft is damaged or the intermediate shaft bearing is damaged, and the gearbox should be opened to check the intermediate shaft.

5. If there is a continuous high-frequency abnormal sound in a certain gear during driving, it is generally the metal friction and peeling off the surface of the gear, and the gear gear should be replaced in serious cases.

6. If it is a periodic sound, it is mostly a broken individual wheel tooth, you should stop and check the gearbox first, if it is serious, you should call a tow truck to tow the car to the maintenance shop for maintenance, so as not to cause greater losses.

Hello, Ethereal high-speed oil sheathing squeak may be a manifestation of engine fuel system failure, which may be due to fuel filter squeeze squeak, insufficient oil pressure, oil pump, oil pump or oil pump drive shaft and other fuel system components failure. It is recommended that the owner carry out engine inspection at high speeds, check the engine oil and oil impurities, and check the wax parts of the fuel system; If it is determined that there is a fault, the damaged parts should be replaced in time, and the quality and certificate of the parts used must be paid attention to to ensure the normal operation of the vehicle. Secondly, the abnormal noise of the nuclear oil at the high speed of the Ethereal may be a problem with the engine oil pump or the drive shaft of the oil pump.

Because the oil pump filter element is clogged with dirt, the dirt accumulated in the engine oil circuit will be evenly distributed at the filter element, causing the oil pump filter element to be blocked by fouling, and the driving shaft may be worn out if the oil pump is well driven, so there will be noise. At this time, the filter element should be cleaned and replaced, the wear of the drive shaft of the oil pump should be checked, and if necessary, it can be replaced. If not dealt with in time, it may lead to damage to the engine oil system, which will greatly affect the service life of the engine.

There is a problem with the gears of the transmission. Tian Lai is a well-known car brand in Hengsan, cost-effective, practical, high-speed oil sheathing abnormal sound is a problem in the gearbox gear meshing, should be maintained in time to lift the mold.

Hello, there may be the following reasons for the abnormal sound of high-speed oil harvesting in Ethereal:

1.Fuel problem: It may be that the fuel is impure or the fuel contains impurities, resulting in incomplete combustion, resulting in abnormal noise.

2.Ignition system problems: It may be that there is a problem with the ignition coil or spark plug, resulting in poor ignition, resulting in abnormal noise.

3.Exhaust system problem: It may be that there is a problem with the exhaust pipe or muffler, which causes poor exhaust and abnormal noise.

4.Engine problems: It may be that there is a problem with the internal parts of the engine, such as pistons, connecting rods, etc., which causes the engine to run unstable, resulting in abnormal noise.

It is recommended that you go to a professional car repair shop for inspection and repair in time to avoid more serious problems. Rough collapse.

High-speed oil squeezing can be caused by a variety of reasons, among which the following are common: the hand is not clear.

1.Damage to engine parts: For example, crankshafts, connecting rods, pistons, and other parts are worn, loose, or damaged, which can cause the engine to produce abnormal noises.

2.Oil pump failure: The oil pump is not working properly, such as the oil pump pressure is too high or too low, and the internal accessories of the oil pump are damaged, which will cause abnormal engine noise.

3.Oil quality Bina problem: The use of inferior lubricating oil or deteriorated lubricating oil will increase the friction between engine parts, resulting in abnormal noise.

4.Relaxation of the pump transmission belt: causing the pump to work abnormally, which will affect the use of the engine and cause abnormal noise.

It is recommended that you go to a regular car repair service center for inspection and repair in time. At the same time, maintaining the engine and replacing the high-quality lubricating oil are also effective measures to prevent abnormal noise.

The 25-day high-speed skimmer squeak can be caused by a variety of factors, and it is recommended that you go to a professional car repair shop or dealer for inspection and repair. Here are some of the possible reasons for this problem:

1.Fuel filter blockage: After using the fuel filter for a period of time, it will accumulate sediment, reduce the fuel flow, and cause the engine to have an abnormal sound of oil collection at high speed.

2.Air filter blockage: Air filter blockage restricts air inflow, depriving the engine of oxygen, and causing oil squeaks and squeaks at high speeds.

3.Ignition system problems: Ignition system failures can cause fuel to fail properly, resulting in squeaky and squeaky oil harvesting at high speeds.

4.Automotive sensor failure: The automotive sensor is responsible for monitoring the operating status of the engine and sending signals to the computer control module. If the sensor is faulty, it can cause an oil squeak at high speeds.

It is recommended that you go to the designated repair shop or dealer as soon as possible for an inspection and to make appropriate repairs or replacement parts according to the advice of professional technicians.

25 Sounds of high rpm squeak can be caused by a variety of reasons, here are some common possibilities:

1.Air Cleaner Problem: If the air filter is too dirty or damaged, it will cause insufficient air intake to the engine, resulting in abnormal noise.

2.Oil Pump Problem: The oil pump works more frequently and nervously at high speeds. If the oil pump is malfunctioning or aging, it may cause abnormal noise when rewinding.

3.Internal problems of the engine block: such as damaged or aging parts such as pistons and connecting rods, may also lead to abnormal noise at high speeds.

4.Exhaust system problems: Carbon deposits and deformation in the exhaust pipe may affect the emission effect, and it is easy to produce noise at high speeds.

It is recommended that you go to a regular car repair shop for inspection and repair in time. At the same time, it is necessary to pay attention to the maintenance and maintenance of the car in daily use, and regularly replace the air filter, oil and other lubricants or slip agents and other consumable parts.

There are several possible reasons for the abnormal sound of high-speed oil collection of Ethereal vehicles:

Blockage of the air filter: The blockage of the air filter will lead to poor air intake of the engine, which will affect the normal operation of the engine and produce abnormal noise. It is advisable to check if the air filter needs to be replaced.

Poor quality gasoline: Poor quality gasoline can also cause abnormal engine noises. It is recommended to use high-quality gasoline and carry out regular cleaning and maintenance.

Engine failure: When driving at high speeds, parts inside the engine may fail, such as valves, pistons, valve springs, etc. These can cause abnormal engine noise, so it is recommended to go to a professional maintenance site for repair and maintenance in time.

In short, the problem of high-speed oil sheathing and abnormal noise needs to be investigated and dealt with in time, and the problem should be found and repaired as soon as possible to avoid more serious damage caused by stuffiness. If you can't solve the problem yourself, it is recommended to go to a professional car repair station for overhaul and maintenance.

Generally, in the case of insufficient torque rubber, it is easy to occur. The presence of the most common abnormal noise in the engine depends on the speed state of the engine. 1.

The reason for the sound: the gap between the piston and the cylinder wall is too large; The piston pin assembly is too tight or the connecting rod bearing assembly is too tight; The gap between the tappet and the guide hole is too large; Wear of the valve cam profile; Sometimes, the starting gear is loose and the pulley goes off (noticeably when shifting). 2.

Identification method: A lot of abnormal noises on the engine are obviously related to its load. During the diagnostic process, tests can be carried out by uninstalling them one by one.

Single-cylinder or double-cylinder ignition is usually used to reduce the load on one or two cylinders to determine the relationship between abnormal noise and load.
