What is the reason for the abnormal beating of the Volkswagen Magotan timing pulley

This is easy to mismatch the tooth top valve, you need to pay attention. There's a solenoid valve, right above the timing shell.

Does Magotan have timing belts Isn't it a chain.

The front wheels of the vehicle make abnormal noises, know what may be the causes of abnormal noises, and check and repair the vehicles accordingly.

Possible causes of squeak and squeak:

Front shock absorber failure.

The front-wheel drive half-shaft is loose.

The chassis screws and rubber components are loose, and the ball joints and bearings are loose.

Inspection steps: Lift the vehicle with a lifter, check whether the screws and rubber components at the front end of the chassis are loose, disassemble the front shock absorber to check whether the shock absorber is good, remove the front wheel to check the front wheel bearing, check whether the front wheel drive half shaft is loose, and finally judge the cause of the failure, and replace the spare parts in the remaining beat.

The relationship between abnormal noise and the working cycle of the engine is that the abnormal noise fault of the motor is often obviously related to the working cycle of the engine: the piston strikes the cylinder wall; the knocking sound of the piston pin; piston top cylinder head; The connecting rod bearings are too loose, and the sound is still present when maintaining high-speed operation. The causes of the ringing are; piston deformation; The clearance of the piston ring is too small; Piston pin break:

premature ignition due to overheating; The camshaft timing gear is radially broken: the piston pin copper sleeve is loose. A cylinder is out of flame.

The relationship between the sound of the different ruler and the temperature, the sound is reduced or even disappeared after the temperature rises, and the sound appears at this time. The reasons for the sound are: all the sound caused by the crank connecting rod mechanism is the work of the engine, and it is sounded twice at a time; All the sounds caused by the valve mechanism are the work of the engine, and the sound is sounded once. In general, the noise caused by clearances unrelated to the duty cycle is mostly due to faulty engine accessories, and the sound is aggravated

The connecting rod bearing is loose, the bearing is melted, or the size does not match and rotates. There is a sound when the temperature rises; If there is a continuous metal friction sound emitted by a mechanical part that is not related to the duty cycle, it can be considered that some rotating part is faulty.

The relationship between the abnormal noise and the engine part is when the engine makes abnormal noise; The crankshaft bearing is loose or the bearing is burned, and the sound is reduced or disappeared when the temperature is reduced. There are many reasons for the sound, if the abnormal noise is not related to the work cycle; Piston pin break:The causes of the ringing are;

The crankshaft bearing is loose. The sound is disordered when it is maintained at a certain speed, and it makes a brief sound when it decelerates sharply; Sometimes, the starting grip is loose and the pulley makes a sound (which is noticeable when the speed changes); The long and minor axes of the piston skirt oval are opposite; The piston ring is leaking. Abnormal noise occurs when the engine accelerates sharply; loose valve seat inserts; Valve jamming can not be closed:

The gap between the piston and the cylinder wall is too large; The piston pin assembly is too tight or the connecting rod bearing is assembled too tightly; The flywheel retaining bolts are too loose.

Or the timing belt is not installed properly. The tensioner needs to be adjusted by turning the water pump, and if the tensioner is not adjusted properly, there will be a sound. Mine is like this, the first time the 4S shop map is trouble-free without adjusting the water pump and directly installing the timing belt, which is very noisy.

I reinstalled it in a different place, and it was normal.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! If the timing pulley jumps, it is a wheel problem.

1.There is a spline inside the timing pulley, and if the spline is smoothed, it will cause the wheel to jump and rattle. 2.

The pulley surface needs to be inspected. If there is no problem with the surface, remove the pulley and check the spline inside.

There is a spline inside the timing pulley, and if the spline is smoothed, it will cause the wheel to jump and rattle. 2.It is necessary to inspect the surface of the pulley.

On the surface, there was no question about the wheel, so I dismantled the pulley and checked the spline inside.

The chain and tensioner pulleys that have just been replaced are noisy.

Check the engine speed when there is noise. If there is an abnormal noise in the case of idling, it is generally a problem with the pulley.

What do you have to do in exchange for this?

Check the specific problem before deciding on a replacement accessory. It is usually the timing chain that rings there.

How to deal with the sound of the Volkswagen Suteng timing belt? Volkswagen Sutar ( Price |Detailed explanation of the model) How to deal with the timing belt ringing? The treatment method of Volkswagen Sutar timing belt ring is to replace the timing belt positive pin or adjust the tensioner.

The main function of the engine timing belt is to drive the valve mechanism of the engine to open or close the engine intake and exhaust bucket doors at an appropriate time, so as to ensure that the engine cylinder can be suction and exhaust normally. The following are the replacement steps of the timing belt: 1. Disassemble the valve chamber cover, disassemble the crankshaft pulley, and remove the timing chain shell; Rotate the crankshaft, turn the crankshaft to the top dead center of a cylinder, screw the crankshaft fixing screw, and fix the crankshaft; 2. Rotate the intake and exhaust camshaft, there is a groove at the rear end of the camshaft, align the grooves of the two camshafts in a balanced manner, and snap the special tool into it; 3. Remove the old chain and replace it with a new one.

The crankshaft pulley is also without a slide key, and when installed, there is a round hole on the pulley, which is aligned in the groove above the chain shell; 4. The crankshaft position sensor can be adjusted, and the gap should be adjusted in place during installation, otherwise the fault code will be reported; Both the crankshaft sprocket and the pulley rotate freely. @2019

This phenomenon is often seen. I used to have a repairman. The customer requests a belt to be replaced.

At that time, the engine did not make any noise. When he finished changing the timing belt. There was a beep after starting.

I asked the repairman. The sound came there. He said he didn't know.

I said that there was no sound in front of the belt when the car was realigned. And when you change the timing belt, it will make a noise. It's so hard that it doesn't explain the problem.

He still didn't know.

The wear gap between the outer ring of the bearing and the inner diameter of the bearing seat is too large, the wear gap between the inner ring of the bearing and the diameter of the shaft is too large, and the lack of oil in the bearing causes heating.

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 leakage; 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.

How to identify the sound of a car:

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 made by the dry friction of the bearing, and the "click" sound similar to the light hammer hitting the concrete floor made 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 avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), 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 wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation 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.
