The gear oil has just been poured in, it is a cool reddish-brown, and after operation, due to temperature and oxidation and other reasons, it has become black, and now, in the soaking of black gear oil, those gears are waiting for Liu Jianzhi.

This kind of reducer, the most commonly used is the combination of planetary gears, a shaft inside, is a main gear, the outside is a few pinions, the pinion revolves around the big gear, just like the planet revolves around the star, this structure, Liu Jianzhi is familiar, except for the straight teeth replaced by helical teeth, but he doesn't know the other doorways.

Now, being stared at by Zhao Guodong, Liu Jianzhi doesn't know how many times he has been scolded in his heart, why hasn't Zhao Guodong left today? As for this Qin Zhenhua, he is clearly looking at his own jokes.

He tentatively tinkered a few times, and then said to Qin Zhenhua: "Okay, put it on and try it." ”

All right? Zhao Guodong looked at Liu Jianzhi seriously, what are you kidding, just make a few tinkers like this, that's good? Didn't fix it at all, right?

"Qin Zhenhua, pay attention when assembling, if there is another failure just now, it must be a problem with your installation." Liu Jianzhi said.

If it continues to ring for a while, it will all be on Qin Zhenhua's body, hum, let you see my joke!

"Master Liu, this, how to install it, I will only disassemble it, not install it, after all, this is the first time I have disassembled it." Qin Zhenhua said.

What the? Master Liu's face was as black as a piece of charcoal, and he originally planned to shirk the responsibility to Qin Zhenhua, but now, when Qin Zhenhua said this, he kicked the ball back.

"That's right, Qin Zhenhua is only a three-day apprentice, dismantling things is still neat, if you pretend to be inappropriate, I'm afraid that it won't be suitable, Lao Liu, you pretend, let's try it." Let the troops see our efficiency, so that the commander of the tank division always scolds his mother on the phone. Zhao Guodong said beside him.

Liu Jianzhi's eyes bulged, and he glared at Qin Zhenhua fiercely, Qin Zhenhua was humble: "Master Liu, what wrench do you want, I'll get it for you, we have to hurry, Director Zhao has said, let the troops see our efficiency, you are a master, install this thing, it must be fast." ”

In this way, it is impossible for Liu Jianzhi to even delay time, although he has a black face, he has to continue to pretend, perhaps, he will make it better like this, yesterday, Qin Zhenhua was like this!

Thinking of this, Liu Jianzhi also got upset, hurriedly installed the partial cover, and then installed the tracks, and soon, the tank was repaired.

"Where's Lao Zhang? Come on, give it a try. Zhao Guodong shouted, Zhang Xiangqian was getting off a tank, and when he heard Zhao Guodong shouting, he immediately ran over.

"Another 69?" Zhang Xiangqian said: "Open the partial cover again?" It looks like yesterday's breakdown. ”

"That's it, let's try it." Liu Jianzhi said, for fear that Zhang Xiangqian would say too much and shake out yesterday's events.

Zhang Xiangqian's hands and feet were nimble, he went up to start the tank, put on gear, and just released the clutch, he heard a loud sound, this time, it sounded even louder!

"Park, park!" Zhao Guodong shouted: "It's not repaired at all, it's even worse!" ”

I was expecting it to be fixed all at once, but why did the fault become more severe? If Qin Zhenhua pretended to be just now, he could still be counted on to take the blame, but now it is absolutely impossible.

"No, yesterday, wasn't it repaired quickly? Zhenhua, what's going on? Zhang Xiangqian asked Qin Zhenhua.

In the morning, Zhang Xiangqian came very early and went out to test the car, so he didn't know everything here, and now, he looked at Qin Zhenhua very strangely, and this look immediately made Zhao Guodong understand something.

Zhao Guodong's eyes stared at Liu Jianzhi, Liu Jianzhi's hands were on his back, constantly rubbing his work clothes, and then he finally raised his head and looked at Qin Zhenhua: "Zhenhua, why don't you come and take a look?" ”

"I'm an apprentice, you're a master." Qin Zhenhua said: "You can't repair a master, where do I dare to look at my apprentice, I am learning from you." ”

Master, apprentice, these words were placed in Liu Jianzhi's ears, particularly harsh, just now, he was still trying to pretend to be a master, but now, it has all changed, his appearance makes Zhao Guodong even more wondering: "Lao Liu, didn't you repair the 69 tank yesterday?" ”

"Yesterday, I didn't say I did it." Liu Jianzhi muttered, he really didn't say anything yesterday, it was Liu Dajun who said it, of course, that sentence is misleading, but today, Liu Jianzhi's performance is completely a master's style.

However, this sentence only dared to mumble quietly in his mouth, at this time, his face was almost red, it was really embarrassing, as a master, he was not as good as an apprentice, just now, he had been pointing fingers, hoping to put it on, but now, it is still exposed.

"Qin Zhenhua, yesterday's car, you repaired it?" Zhao Guodong asked Qin Zhenhua.

"Master Liu, how did you report to Director Zhao about yesterday?" Qin Zhenhua continued to ask: "Looking at your performance in the morning, I can only keep pretending." Didn't you watch me fix it yesterday, why haven't you learned it yet? If you had learned it yesterday, you wouldn't have looked foreign today. ”

After speaking, Qin Zhenhua said to Zhao Guodong: "Director Zhao, I'm sorry, you really can't blame me for this." ”

This expression, this tone, is clearly saying, Liu Jianzhi wants to be a master, I, a small apprentice, can't steal Liu Jianzhi's limelight, I repaired it yesterday, and I also taught Liu Jianzhi, Liu Jianzhi wants to grab credit, and I have to let it as an apprentice, this morning, I have been an honest apprentice here, and I have given face, and I have a lining, but Liu Jianzhi is helpless, and he didn't learn, which leads to a fool now.

"You." Liu Jianzhi listened to Qin Zhenhua say this, and suddenly he was speechless, you made it so fast yesterday, how can I see it clearly? Moreover, I'm a teacher, do I still use you, an apprentice, to teach?

Liu Jianzhi has been in the maintenance workshop for more than ten years, and the shelves have long been there, when have he been so angry, but Zhao Guodong is beside him, and he can't say anything.

"Okay, Master Liu, take a good look at it, I'll show you it again and see how to eliminate this kind of failure." Qin Zhenhua said that now his tone, like that of the old master, began to educate apprentices.
