Chapter 239: Rebel

"Accident car?" Manager Wang was upset, and took a step forward to question Song Guoyuan, "You tell me where the accident is?"

"Look here. Song Guoyuan's fingers stroked the paint on the roof of the car, but he quickly shook his hand with disgust, as if he felt dirty.

In order to explain the location and cause of the accident, Song Guoyuan endured his nausea, and his helpless fingers swiped the side of the roof from the front to the back again, signaling to everyone: "There must be a long heavy object that hit this location......"

Pointing out the direction of the accident, Song Guoyuan took off part of the adhesive strip that had just been installed, and asked everyone to come over to see the residual paint: "There will never be such paint defects in the regular OEM spraying, and the only explanation is that the roof is painted with sheet metal." ”

Manager Wang and the others came to the front, hooked their heads and looked at the area pointed out by Song Guoyuan, and sure enough, they found a little white paint mixed in the gaps, this location is too hidden, if it is not an experienced master, it will take some effort to find out.

However, Manager Wang, including Wang Hu and others, didn't know anything about car maintenance, and they saw it in vain, and the only ones who knew what it meant to have residual paint were Fang Yuan and Sun Yanming.

Fang Yuan was pretending to be stupid and didn't speak now, but Sun Yanming couldn't help nodding as if he had been empowered, and completely understood what was going on: "No wonder I used a paint film meter to check the roof of the car, there are a few subtle places where the paint data is very high, it turns out that I have done paint." ”

After Sun Yanming sighed, he smiled bitterly and thought that his car condition appraisal level was really not good, if Fang Yuan hadn't accidentally discovered the residual paint, he would have taken the accident car and put it in the car dealership for sale.

"It's really a blessing for me. Sun Yanming turned his head to look at Fang Yuan, his eyes full of gratitude and appreciation.

Finding that Manager Wang and the others were still in a state of confusion, Song Guoyuan reinstalled the rubber strip and pointed to the rear door hinge next to him again and said: "There are generally two common door hinges for car doors. ”

(Here, when picking off the rubber strip to check the solder joints, etc., you have to pick it up one by one, and if you pick off all the rubber strips at once, you will be beaten to death by the car dealer, and some models will not even be able to install the rubber strips.) ）

"Hey, brother, let's talk about the accident car, why are you mentioning the door hinges?" Sun Yanming was a little puzzled, and Song Guoyuan suddenly said what the rear door hinges of this car were trying to do.

"Fang Yuan, come here. Song Guoyuan didn't pay attention to Sun Yanming, and motioned for Fang Yuan to walk next to him, he was not so much explaining to Manager Wang and the others, but rather to give Fang Yuan a lesson in opening a small stove, "Do you know which two?"

"I know that. Fang Yuan thinks this is very common knowledge, "one is the cast door hinge commonly used in European and American car series, and the other is the stamped door hinge commonly used in Japanese and Korean car series."

Stamped door hinges have low manufacturing cost and save money, but its strength is not so great, it can not bear too much weight of the door, after a long time, frequent opening and closing of the door, there will be problems such as the door sinking, unable to close completely, abnormal noise, and difficult to close the door. Therefore, the door with stamped door hinges must not be heavy, and the impact resistance in the event of an accident is not very good.

The cast door hinge is formed at one time, the structure is simple and stout, the strength is high, the manufacturing precision is high, the cost is higher, of course, it can withstand the heavier door, the door sinks, can not be completely closed, abnormal noise, the door is difficult to close and so on. ”

"Well, yes, yes. The door hinge of the door is indeed the most basic knowledge, Fang Yuan can answer smoothly, Song Guoyuan did not feel a little surprised, "If the door is impacted, it needs to be sheet metal or replaced, it can be judged from the disassembly and assembly traces of the door hinge screws." ”

Fang Yuan nodded, of course he understood that when he twisted the screw, the paint on the surface of the nut would be damaged, and even the nut itself would be damaged.

"You have to remember that this is just a normal way of judging. Song Guoyuan said to Fang Yuan very seriously, "Sometimes I will replace new screws, new door hinges, and wrap the nut with cotton cloth and other methods and then twist it, etc., and I can't detect it." ”

"Oh, I'll go, what else can I do?" Fang Yuan really didn't know this kind of trick, and the surprise on his face was really not faked.

Song Guoyuan taught the apprentices on the spot, and Liu Liang and others were also very curious, and felt that they had learned a lot of things.

Liu Liang noticed that Song Guoyuan had been emphasizing the matter of door hinges, and he hooked his head to look at the two rear door door hinges of this Mazda Ruiyi.

This kind of door hinge has a simple structure and a thin material, and Liu Liang doesn't have to guess to know that it is the kind of stamped door hinge that Fang Yuan said.

Carefully checked up and down according to the method Song Guoyuan said just now, Liu Liang finally determined that the paint surface of the four nuts on it was intact, and there was no trace of twisting, and finally raised his head and looked at Song Guoyuan in confusion: "Master Song, there is no problem with the hinges of these two doors, right?"

Song Guoyuan smiled at Liu Liang, just now Liu Liang stood firmly on Fang Yuan's side, not afraid of Manager Wang, the superior leader, he is far from the other party, and he is his apprentice's fellow countryman and friend, Song Guoyuan gave him face very much, and explained very seriously: "The young man sees it very accurately, and there is really no problem from the surface of the nut, but you look here......"

Song Guoyuan bowed his head and bent down and pointed to the bottom of the door hinge at the bottom: "The problem is here." ”

"Huh?" Fang Yuan was also curious about what was going on, and leaned over with Liu Liang to check.

Eyes carefully scanned the bottom of this door hinge for a while, Fang Yuan finally found a problem, its paint and the nearby body have no color difference, but the material at the bottom is slightly deformed, but the degree of distortion is not very large, and it is really impossible to see if you don't look carefully.

"Awesome, awesome. After finding the reason, Fang Yuan and the others cast admiring glances at Song Guoyuan, "You can see this." ”

"I know my rebel too well. Song Guoyuan was embarrassed to explain to everyone that his traitor Wang Jialiang was highly skilled and talented, especially in maintenance and maintenance, and his achievements were more powerful than his master.

However, Wang Jialiang also has shortcomings, and they are fatal shortcomings.

According to Song Guoyuan's words, he is stingy, snarky, and values money more than life.

As long as it is not the kind of car that is repaired regardless of the cost, Wang Jialiang can save money, and he is not willing to waste a penny more, a small part.

Take this Mazda Ruiyi as an example, he has already done a good job of the sheet metal paint on the roof and the door hinge screws, but he has not removed the paint residue in the gaps and directly replaced the new stamped door hinges, but still uses the old one to save money.

"If such a person has a bad realm and mind, he can't achieve great things. Song Guoyuan said that he judged from the maintenance technology and the flaws left behind that it was Wang Jialiang's method.
