How to remove the inner bearing after removing the tire?

Tools: jack; Sleeve 19MM (unloading wheel); Sleeve 15MM, remove brake caliper and brake caliper seat; Unloading wheel bearing with sleeve 13MM, long skirt sleeve 34MM, unloading shaft fastening nut; T25, remove the brake disc screw.

Working procedure:

1, find a flat position to park the car and release the foot brake. Before and after the other three wheels, the masonry fixed wheels are padded. Lift the vehicle. Remove the tire.

2. Remove the brake caliper, and fix the brake caliper on the damping strut with iron wire. Remove the brake caliper seat. When removing the calipers, the hydraulic jacking seat will press the brake pads. You can push the hydraulic jacking seat back with a hammer handle or a screwdriver (C-clamp is used in the maintenance manual).

3. Remove the brake disc fastening screw with T25, and remove the brake disc.

4. Remove the axle fastening nut with a 34 mm long skirt sleeve. (Be sure to use a 34MM long skirt sleeve or heavy sleeve, which can't be removed by ordinary ring wrenches. )

5. Remove the ABS plug.

6. Remove the wheel bearing and three 13MM fastening bolts.

7. Place the wood square on the axle, tap the wood square and remove the wheel bearing. (Use the three-jaw puller to unload the manual. The simple way is to tap lightly on the wooden mat, not hard. If you use too much force, the post will be knocked off and the four wheels will be out of alignment. )

Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on the metal rim, it can support the car body, buffer the external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used in complex and harsh conditions. They are subjected to various deformations, loads, forces and high and low temperatures during driving, so they must have high bearing performance, traction performance and cushioning performance. At the same time, it also requires high wear resistance and bending flexibility, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tire to consume rubber.

The earliest tires were made of wood or iron, which can be seen from the ancient chariots in China and the gentry carriages abroad. Later, when the explorer Columbus explored the New World for the second time in 1493- 1496 and arrived at Haiti Island in the West Indies, he found the rubber blocks where local children were playing, which surprised him. Later, he brought this wonderful thing back to the motherland. After several years, rubber was widely used, and the wheel gradually changed from wood to hard rubber. But at this time, the rubber tire is still solid, and it is still very uncomfortable and noisy to walk. It was not until 1845 that R·w· Thomson, a Scottish-born civil engineer, invented pneumatic tires and obtained a patent from the British government on the topic of "wheel improvement of vehicles such as carriages". The first pneumatic tire was born in February 10 of the same year. The first person who bought pneumatic tires was named Li Luo, a nobleman. The total price of the four tires is 44 pounds and 2 shillings. 1847, Scientific American magazine introduced Thomson's pneumatic tire, calling it an epoch-making improvement. However, Britain at that time paid too much attention to the traditional middle class. In order to protect the carriage,

In order to limit the development of steam cars, the speed of cars is limited to 2 miles per hour (about 3.2 kilometers) in urban areas and 4 miles (about 6.4 kilometers) in suburbs. In this way, Thomson's invention has no market, and it is slowly forgotten by people. That is to say, Thomson's first tire revolution did not bring the same light as the sun to mankind, because the darkness that human beings should experience seems to be not over yet. But the sun will always come out, because human beings and everything need it. More than 40 years later, in 1888, Mr J·B· Deng Lupu, an Englishman who was a veterinarian in Ireland, obtained the patent of pneumatic tire. At that time, Johnny, the son of Mr. J·B· Deng Lupu, who was 10 years old, bought a three-wheeled bicycle, but because the tires at that time were all solid tires made of hard rubber, it was very uncomfortable to walk on the stone road. His son's complaint inspired Mr. Deng Lupu, so the pneumatic tire that had been forgotten for more than 40 years came out again. With the progress of the times, the pneumatic tire invented by Mr. Deng Lupu was quickly applied to bicycles and quickly entered the automobile field, making great contributions to the development of the world automobile industry.
