It is not easy to perform major surgery on the BJ212, although at present, almost all car factories have access to a complete set of technical drawings for the car. That can only be imitated, and there will be any automobile factory whose technical strength can compare with the original factory, and the original factory is not good at modifying, let alone the auxiliary factory.

Hongxing Factory is not an ordinary auxiliary factory, when he built the factory, he already had top technicians like Ma Jintao, and the comprehensive technical personnel he brought were not comparable to many provincial automobile factories combined.

The most important thing is that the Red Star Factory has a variety of off-road vehicles produced by Japanese car companies, although there are no drawings, but it can get some inspiration and guidance through disassembly research.

The most important of these is chassis technology.

In charge of the project is Liu Guobing, another of Ma Jintao's high-ranking disciples.

The students led by Ma Jintao have such characteristics - they specialize in materials research, and they all have the ability to develop a certain subsystem. Just like Ma Jintao, he is an all-rounder, Taishan Beidou in the field of materials research, and has deep attainments in process technology and overall engineering.

In this aspect, he is even better than Pei Lei.

One thing must be admitted, the technologists of this era are really real. Unlike those experts and professors who relied on copying papers and reviews their titles decades later. The technicians of the 60s worked for 30 or 40 years until the first decade of the 21 st century, is it really because they are in good spirits, no, it is because they must have such really talented old people as they sit in charge and engage in scientific research.

China's scientific research personnel are not sleeping on their laurels, but they are overdrawing their lives until the end of their lives, so there is a great leapfrog development of China's military industry and the frequent phenomenon of overtaking in corners.

In the vehicle test site, the technicians of the project team surrounded an off-road vehicle that was larger than the modified models used by Fox Hunt and Evil Fox without paint.

To Li Lu's surprise, Sun Jiangtao was also there.

Sun Jiangtao stayed in the New Guangming Factory, he is an important resource of the Guangming Factory, Wang Jiaqing will not fake his hands to others, and he will not even give it to the Red Star Defense Company. The eight King Kongs of Guangming Factory, that is, the eight eighth-level fitters, were all left in the current new Guangming Factory by Wang Jiaqing. In Wang Jiaqing's view, without the New Bright Factory of the Eight King Kongs, at least half of its strength has been lost.

Therefore, after the handover of the Guangming Factory, Li Lu also hadn't seen the workers and masters in the original factory for a while, after all, it was not as good as before, and it was not so convenient to borrow.

Sun Jiangtao was at the scene, and he felt strange because of this.

"Master Sun, why are you here?" Li Lu walked a few steps quickly to greet Sun Jiangtao.

The weight of the eighth-level fitter is obvious, and even Ma Jintao is polite to Sun Jiangtao. Technicians can design the workpiece with precision, but to turn the drawing into a real workpiece, it must go through the hands of the worker. And the eighth-level fitter is the general among the workers, the top existence.

Without workers, no matter how good the drawings drawn by technicians are, they are still in the air, and without top workers, no matter how accurate the drawings are, they can only be drawings after all.

For the eighth-level fitters who can control the error of the workpiece in the equivalent of the hair diameter, there may be only one statement that is accurate - every eighth-level fitter is a national model worker, and not all national model workers are eighth-level fitters.

To become an eighth-level fitter, in addition to talent, it requires day and night labor.

The reason why Sun Jiangtao, who is in his forties, is the head of the Eight King Kongs, in addition to his skills, age is an absolute advantage, because he is the youngest one. One can imagine how much work it took him to comprehend the slightest error control in the past.

Sun Jiangtao held his right hand behind his back, and he was smoking a cigarette in his left back, spitting out a cigarette and laughing but not speaking.

Liu Guobing, who was standing beside him, said, "Third brother, we asked Master Sun to come over and help process a workpiece, it's been a few days." ”

Li Lu took out a pack of cigarettes from his pocket, stuffed them into Sun Jiangtao's pocket, and said with a smile, "Master Sun, thank you for your hard work." ”

Sun Jiangtao was very satisfied.

It's not that he lacks cigarettes, nor does he have a good smoke. Not to mention the treatment of the new Guangming Factory, after the transfer to the locality, the treatment is better than before. He came to the Red Star Factory to help, and the Red Star Factory was serving with good cigarettes and wine, all of which were going to the highest standards.

However, the cigarette given by Li Lu is a manifestation of status.

Sun Jiangtao pointed to the prototype No. 1 of the little white rabbit surrounded by everyone, and said, "The strength of a workpiece in the transmission shaft is not enough, and if you use high-strength steel, some young people can't get this accuracy, so I'll come over to help for a few days." ”

"Master Sun, as soon as you get out of the horse, it will definitely be no problem." Li Lu said.

Sun Jiangtao waved his hand and said, "Don't be in a hurry to pat yourself on the back first, try the car to see the effect." ”

Liu Guobing explained, "The third brother, the fox hunting and the evil fox models all have the same problem, and the torsion resistance of the transmission shaft is not enough. With a higher-horsepower diesel engine, we matched the new engine to a four-speed manual gearbox. However, after a period of use, it was found that the torsion resistance of the propeller shaft was insufficient. In this batch of modifications, we mainly solve this problem. There are seven workpieces of the transmission shaft using high-strength steel, which solves the torsion resistance and strength, but there are problems in processing, so I asked Master Sun to come out. ”

Li Lu was surprised and said, "The new engine and the old gearbox are matched?" ”

Liu Guobing nodded and said, "Yes, the main thing is the torsion resistance of the clutch." The processing of the clutch is also a headache, and there are many curved surfaces, and Master Sun still has to come out. So after tossing around for so many days, only one prototype was made. ”

He said with a smile that Li Lu noticed that his fingernails were full of unwashed oil, his hair was messy, and his eye sockets were deep.

This kind of appearance is the norm for many technicians at present, and they are even more desperate than the workers and masters.

"The problem is obvious, it's not complicated to solve, the material basically meets the standard, it's this processing, you Red Star Factory only has one hole Daquan can barely do it, but the speed is too slow." Sun Jiangtao said, taking a puff of his cigarette.

Li Lu said, "Master Sun, I have to trouble you to come over and bring the young people here when you have time." ”

Waving his hand, Sun Jiangtao said, "Just be polite with me." ”

Hehe smiled, Li Lu said to Liu Guobing, "Xiao Liu, let's start." ”

"Yes!"

Liu Guobing ordered, "The first test run of the Little White Rabbit light off-road platform begins!" ”

Each post was in place, and Liu Guobing walked into the car and lit the fire himself.
