Young Master Gu took the part handed over by Old Tang, looked at it carelessly, threw it away and said arrogantly,
“Is it my business that this thing spoils? Do you know I was so fucking embarrassing just now!”
As a result, the part he dropped fell in front of Fang Linyan.
Fang Linyan was originally going to leave. With a move in his heart, he picked up the part and examined it for a while, then he walked to the technician next to the car and said,
“Is the tolerance level of this part reaching IT10?”
The technician took a look at Fang Linyan in amazement. Fang Linyan’s question was on point and it was not a confidential parameter, so he said,
“No, it’s probably around IT12.”
Machining precision was measured by tolerance level. The machining error was expressed by a numerical value; the smaller the value, the higher the accuracy; the higher the machining precision, the lesser the machining error. There were a total of 20 tolerance levels from IT01, IT0, IT1, IT2, IT3 to IT18, of which IT01 represented the highest machining accuracy of the part.
Fang Linyan nodded, then he searched in his bag and found a loupe to put on his head. This thing was originally used by watchmakers to repair watches. It was also called an eyepiece. The others were also slightly stunned.
Immediately afterward, Fang Linyan took out more than 10 tools from his bag. The files alone included plastic file, small file, pull back file, triangular file, etc., as well as bench vice and grinder. There were still a few self-made tools that no one else knew.
Fang Linyan’s speed was extremely skilled. He assembled a temporary workbench for fitter almost in the blink of an eye, then he looked at the part carefully and then began cutting.
Everyone’s attention was on the car, and they didn’t notice Fang Linyan’s actions. Only the technician was stunned. Only 3 minutes later, Fang Linyan finished his work. He looked at the processed part in the light, then he said,
At this time, Old Tang had already let Young Master Gu sit inside. The only 1 guarding the car was the technician as well as the brat and Director Deng. They were initially here to see their peers making a fool of themselves, but they happened to see Fang Linyan’s operation.
Fang Linyan came to Corvette and reinstalled this part. The technician hurriedly stopped,
“Hey, hey! Why did you install it?”
Fang Linyan ignored him, squinted at the engine, and then carefully inspected it. Then, he took out a tube from the top, removed it and polished it carefully. The expression of the technician changed, but he just talked about it; he didn’t intend to stop him.
Because this person had a deep scheme, knowing that Young Master Gu was not a reasonable person. It happened that someone like Fang Linyan took the initiative to get involved. If he couldn’t fix this (In this technician’s mind, this was almost a high probability event. ), why shouldn’t he let Fang Linyan take the blame? At least he could shed most of the responsibilities.
Fang Linyan’s actions were very fast. The series of actions of disassembly, polishing, and reinstallation was almost done in one go. He completed the work in just 5 minutes, then he began to conduct a careful inspection again as well as debugging. During the inspection, he also used a wrench to tap, a finger to flick, etc as if he could know what was wrong judging from the sound of tapping.
At this time, that Young Master Gu walked out from inside with a sullen face and was cursing. Boss Tang kept apologizing. Because the workers of the shop all wore the same uniform, so Fang Linyan, who was fixing the car, looked very conspicuous. Young Master Gu said angrily,
“Hey, what are you doing?”
Fang Linyan raised his head and glanced at him indifferently,
“Wait another 2 minutes, if there is no problem, you can drive away.”
“Huh?” Young Master Gu was dumbfounded.
Old Tang had already made it clear to him that if he wanted to race with this car, he had to wait for the high-precision part from Europe. If he was lucky, it may arrive tomorrow; not lucky, half a month at least.
If a second-hand disassembly part was used, there was no guarantee that there would be no problems to race.
Young Master Gu finally accepted this fact. He didn’t expect that as soon as he left the shop, this kid told him that he would be able to drive away in 2 minutes! ! However, people always like to hear good news, and Young Master Gu, a rich, powerful and willful person, was no exception. He said with some surprise,
“Really? I can drive away in 2 minutes? Can it race?”
Fang Linyan said lightly,
“Yes, and I just optimized it to increase the coefficient of performance of the four items: the ignition advance angle, the amount of fuel injection, the time of fuel injection, and the concentration of the combustible mixture by about 5%. In this case, the mid-stage acceleration performance of your car after reaching 80km/h will also be improved to a certain extent.”
Hearing Fang Linyan’s words, Young Master Gu’s face was already smiling. He didn’t consider whether Fang Linyan would lie to him, because those who dared to lie to him would usually end up miserably. But after hearing Fang Linyan’s words, several technicians around Old Tang lost their composure as they shouted,
Fang Linyan had already done an inspection at this time, closed the hood and said without bothering them,
After he said that it was done, Young Master Gu was pushed away by the several technicians as he was about to walk up. With a feeling of humiliation, they directly connected a series of instruments and began to test. As a result, amidst the huge roar of the Corvette’s engine, the latest parameters were shown one by one.
This Corvette had always been maintained in this shop, so the previous parameters were very clear to them. After comparing, the technicians looked at each other incredibly. They felt that their worldview was turned upside down. Because this car had not only been repaired, but its performance had really been optimized and improved! It was higher than Fang Linyan’s 5% increase, which was about 7%.
At this moment, Director Deng was dumbfounded, not knowing what he felt right now.
Looking at the expressions of these technicians, Young Master Gu knew the results. He said to Fang Linyan with a smile,
“Awesome! Can I drive away now? Can I race with it now?”
Fang Linyan said,
“Let’s try the car first, neutral gear, full throttle, and try to keep the engine speed above 12,000 rpm for 1 minute. If there is still no problem, it will be completely okay, but remember to change the axle shaft after 2 weeks. The new part should arrive by then.”
Young Master Gu was stunned because the engine speed of an ordinary car was almost at its limit at 7000 rpm. Although his car had been modified, the limit speed was only a little more than 10,000. Previously, the engine got a problem when the engine speed was more than 11,000 rpm.
Therefore, even if Young Master Gu didn’t know much about the car, he clearly knew that if the engine speed could be maintained at more than 12,000 rpm for 1 minute, the car was indeed be repaired.
So Young Master Gu immediately said,
Then he could not wait to get into the car and began to step on the throttle. The rest of the people were startled watching the operation of Young Master Gu. As a result, after the 1 minute test, Young Master Gu came out from the car and said with a delightful smile,
“Yes, not bad! Badass!”
Fang Linyan said calmly at this time,
“It’s fine. The total is 300, thank you.”
When Young Master Gu heard this, he only felt that the asking price was really too cheap. He came here to modify the car, and the cost was not less than 5 figures. He took 5,000 yuan directly from the wallet and threw it to Linyan, then he made a call before driving away to eagerly look for someone to race.
The rest of the people looked at each other. They didn’t expect that things would progress to such a point. Especially Director Deng, he was completely stunned. At the same time, his face was even hotter; he didn’t even have the courage to look at the brat.
After Fang Linyan earned this money, the purpose of coming here had been achieved. He began to dismantle the fitter’s workbench in a hurry and prepared to leave.
Boss Tang certainly wouldn’t let this opportunity go away. He approached with a smile, gave him a cigarette and chatted with him. Fang Linyan knew that he would have to do business with them in the future, so he answered as much as he could, although he didn’t look so enthusiastic.
After the 2 casually chatted for a while, Boss Tang went straight to the subject because he thought Fang Linyan was young and didn’t have any scheme,
“Little brother, I didn’t see you change any new parts just now. How can you fix Young Master Gu’s Corvette?”
Fang Linyan said,
“Isn’t the problem with his car very simple? The axle shaft part is worn. Once it enters high-performance mode, the engine is close to the limit. The flaws on the part cause a series of problems and eventually cause the fault light. Wouldn’t it be enough to reprocess this worn out part?”
Boss Tang was stunned for a while. As a boss, he certainly didn’t know much about technical skills. He only felt that the young man in front of him seemed to be fine, but he always felt that something was wrong.
However, the technician beside couldn’t help it anymore. He said madly,
“That part is not a cheap thing! You thought it was bought online with free shipping and buy 1 free 1? Our boss obtained it from the refitting factory in Mitsuoka, Japan through a special channel, and the price quoted to us was more than 3,000 USD per piece. What’s more, every time we went there late, it was out of stock. How can it be possible to reprocess it?”
Fang Linyan said,
“I took a look. The filing accuracy of this part should be about four thousandths of a millimeter, right?”
The technician thought for a while, then he said in hesitation,
“En, it seems that the filing accuracy is four thousandths of a millimeter in the manual, which is beyond the reach of domestic car companies.”
Fang Linyan said,
“My hand filing accuracy can reach a machining tolerance of one thousandth of a millimeter when needed.”
