Li Weidong picked up the tools and began to disassemble the gearbox of the crown car.

As soon as the so-called experts reach out, they will know if there is one, and this is especially true for mechanical repair. When repairing a car, you only need to look at the disassembly sequence of the mechanic to know how proficient he is in the mechanical structure of the car.

Disassembling the Crown car gearbox, Li Weidong is naturally very skilled, with Li Weidong's understanding of the seven generations of Crown, even if the whole car is completely disassembled into parts, it can be reassembled.

The seventh generation of the crown was born in 1983, when RB had not yet signed the "Plaza Agreement", which was the heyday of RB enterprises, when the number of RB enterprises was very large, and the profits of enterprises were also very good, so it also drove the sales of cars.

Crown is a luxury B-class sedan, more suitable for business, is the boss to talk about business to drive the car, in the RB economy is good, the era of high corporate profits, the crown is the first choice of the bosses, in the RB society has a relatively high number of ownership.

In his previous life, Li Weidong was a trainee at RB for three years and also repaired a car for three years. This kind of seven-generation crown, Li Weidong has not repaired it, so Li Weidong knows the structure of the seven-generation crown very well.

Looking at Li Weidong's skillful disassembly of the gearbox, Liu Jinlong was 100% sure that Li Weidong had repaired this car, otherwise it would be impossible to operate it so skillfully.

"This crown is an imported car, there are only two in the province, this Xiao Li is so familiar with the structure of this car, what is his origin?" Liu Jinlong became more and more surprised in his heart.

After a while, Li Weidong had already dismantled the gearbox assembly, and at this time, the masters in the workshop had already surrounded him, and no one had ever seen the appearance of an automatic transmission.

"What kind of part is this, why haven't I seen it?"

"This is the gearbox, which was removed from the top of the imported crown car. ”

"The gearbox can be made so small! This imported car is amazing!"

"I heard that this gearbox is different from our gearbox, this gearbox doesn't need to change gears, just step on the accelerator and run forward. ”

"Wouldn't you save the clutch without changing gears? ”

Car mechanics, you and I will discuss it word by word.

At this time, Li Weidong picked up the attack and began to disassemble the gearbox assembly.

"Wait a minute, don't dismantle it directly!" Liu Jinlong was taken aback, in his opinion, such a small gearbox must be a very precise part, and he was afraid that it would be broken by Li Weidong.

"Don't worry, I've dismantled this stuff a lot. After Li Weidong finished speaking, he started directly.

Liu Jinlong's heart instantly rose to his throat, for fear that the gearbox would be damaged at all. Li Weidong was very skillful and disassembled the gearbox.

"I found the problem, it's the belt is damaged, and I have to replace the belt. Also, don't forget to bring a transmission oil, it has to be imported, and it will have to be replaced later. Li Weidong directly pulled out the linkage belt of the transmission wheel.

Liu Jinlong asked cautiously: "After changing the belt, can you still put it back?"

"Sure, can you dismantle it or pretend!" Li Weidong said with a smile.

"You're going to have to put it all back in and go. Liu Jinlong then added: "When you opened it just now, the action was too fast, I didn't see it clearly, if you leave, I guess I won't be able to pretend to be back." ”

"I'll fix the car and then go, so it's all right!" Li Weidong paused, and then said: "But you have to take care of the meal, I don't have a meal ticket from your factory." ”

At this time, the crown car driver interjected and said, "This little master, you just need to repair this car, and I will invite you to dinner." ”

Li Weidong looked at the driver of the crown car, then stood up, walked to his side, and said, "Master driver, when you drive, do you often run in neutral gear?"

The driver nodded proudly: "I drive, that's absolutely fuel-efficient." ”

Li Weidong sighed and continued: "If you drive this car in the future, don't run in neutral gear, otherwise the gearbox will be broken." ”

The driver of the crown car was slightly stunned, obviously not understanding what Li Weidong meant.

Li Weidong explained: "This crown uses an automatic transmission, which is different from the structure of our manual transmission. You can't get this wrong. Don't push into N gear while running, the gearbox will break. ”

"Ahh

"N is neutral, but it can't be used like a manual gear. Li Weidong opened his mouth to explain.

The car with the carburetor has a very special operation, that is, after the car runs, hang a neutral gear and let the car "slip" for a distance, so that it is more fuel-efficient to drive.

Because the carburetor of the carburetor does not supply fuel to the engine when it is in neutral.

Therefore, many old drivers drive carburetor cars, and they do not give oil and do not put gears. When the car runs, you need to give the throttle, hang up the gear, go down with one foot on the throttle, and when the speed of the car increases, you will pick it up and run on the neutral gear for a while. This will be more fuel-efficient.

Later, the car engine became EFI, and as long as the car walked again, oil was used, and such an operation lost its meaning.

However, for automatic cars, the car is running and then hanging on the N gear, which is obviously very harmful to the gearbox, and the gearbox is easy to be damaged because of this.

The driver of the crown car does not understand this, he still uses the previous fuel-saving method to drive, after one foot of the accelerator on the N gear, and then use the D gear when you need to refuel, the gearbox will definitely have problems, the first damage is the transmission belt.

Knowing that it was his own improper operation that caused the vehicle to break down, the crown driver suddenly panicked, he was afraid that he would be punished by the leader.

Li Weidong obviously saw the driver's careful thoughts, and he immediately opened his mouth to comfort: "Master driver, just pay attention to driving in the future, don't take it as an example, as for the cause of the failure of this car, I won't tell anyone else." ”

Seeing that Li Weidong was willing to keep it a secret for himself, the driver of the crown car held Li Weidong's hand with a grateful face, and then said sincerely: "Little comrade, thank you, I really invite you to dinner at noon today!"

......

In the repair workshop of the Yellow River Factory, all kinds of parts are still very complete, and about an hour later, Liu Jinlong found a transmission belt that can be replaced.

Li Weidong was about to put the belt back into the gearbox, but Liu Jinlong said: "Xiao Li, can you move a little slower this time, let us see how these parts are installed back." ”

"Brother Liu, you love to learn. Li Weidong smiled, and then said: "Otherwise, let me tell you about the structure of this automatic transmission first?"

"That's great, and I'm just curious about why this gearbox doesn't have to change gears and just keeps running on the accelerator. Liu Jinlong came up as he spoke, then took out a cigarette and handed it to Li Weidong, which was counted as tuition.

Li Weidong glanced at it, fortunately it was not the one he gave to Liu Jinlong.

Li Weidong began to introduce: "In fact, there are two kinds of automatic transmissions, one is hydraulic automatic transmission, the other is continuously variable transmission, this crown uses a continuously variable gearbox, do you see that there are two discs in this gearbox? This is the principle of continuously variable transmission......

As he spoke, Li Weidong simply explained the other parts of the crown car.

Soon, Li Weidong was surrounded by a large group of people, all of whom were masters in the repair workshop, and they were all listening to Li Weidong explain the mechanical structure of the crown car.

In fact, the parts in the car are all the same, and here are all experienced car repairers, who are very familiar with car parts. But when those familiar car parts are put together into an imported car, the car repairers are a little confused.

RB people are more picky about details, which is also reflected in RB cars, and the crown is a business B-class sedan, which reflects the details of RB cars everywhere. This is something that other countries really can't do.

For these car repairers, this crown car is high-end, but also fresh, they can rarely get access to the world-class business car, Li Weidong's explanation, is what they are eager to get the knowledge.

As a result, more and more people gathered around, and some people kept asking questions. And Li Weidong can answer them one by one, after all, his theory of auto repair and his understanding of the crown car are much higher than those of these car repair masters.

......

Wei Bin, the workshop director, walked out of his office, and then saw a group of people gathered together.

"What's wrong?" Wei Bin walked over, and then saw Li Weidong explaining the structure of the crown car to everyone.

"Who is this person, not from our workshop. Somewhat familiar...... By the way, I remembered that there was a company in Qinghe today, and he said that he was coming to visit and study, wasn't that this young man? ”

Wei Bin turned his head and was about to leave, but the next second he suddenly stopped.

"Hey? What's wrong, he's here to study? But looking at this posture, it seems like he's teaching our people! How do you feel that he's here to guide the work!"
