The scooter's belt is broken. Should I change the pulley?

In general, the pulley does not need to be replaced, but if the pulley is defective or damaged, it must be replaced, otherwise the belt life will not be long.

If we change it together like this, it should be no problem. If the pulley and V-belt are of good quality, it will cost about 100 yuan.

It is the case that the normal wear of the belt leads to the end of life, and it is the case that the belt is abnormally worn and broken after the pulley fails. You can judge whether there is a problem with the pulley according to the broken belt.

Just like a motorcycle tire leaks, it is easy to see whether the sharp weapon pierces the inner tube or the outer tire is damaged to cause the inner tube to leak.

Visual method:

Look with your eyes. Is the pulley deformed or discolored (the result of high temperature caused by friction)?

Second, as long as the contact surface between the pulley and the belt is obviously high and low, that is to say, it must be replaced if it is not peaceful. In this case, just feel it with your fingers. ?

Third, after putting on a new belt, did you hear a loud swish when pouring the door? If the noise is loud, the belt seems to rotate unevenly, which is also a problem.

Four smells, the pulley is hot, there is a squeak, and it smells like burning rubber. After changing the belt, I feel that the speed has not improved or even slowed down, which also proves that the pulley is broken.

Extended data:

Scooters are basically stepless speed change automatic clutches, similar to Mulan electric vehicles;

No gear design. After starting, you just need to twist the throttle and leave. When you turn off the throttle, you will automatically slow down gradually until you stop. Moreover, the wheels of scooters are smaller than other cars, and most of the transmission parts are belt transmission, which is commonly called women's motorcycles.

Pedal means that there is a wide pedal between the seat and the handlebar. When riding, you can put your feet comfortably on it, just like sitting in a chair, without sitting astride the car like other cars.

Scooters are one of the important means of transportation for modern children to go out. It fascinates many children and brings serious harm to many families.

But it is a moped between an electric car and a motorcycle. Many parents are in favor of children's buying, but I didn't expect children to be so crazy.
