"Dad, we can't suffer any loss, right? Besides, my brother volunteered. Brother, are you willing?"
Du Chen didn't have to do it anyway, so Du Chen continued to joke with Comrade Lao Du.
"Yes, I volunteered."
Du Bin is working hard now and has no chance to talk to his father and brother. No matter what they say, Du Bin promises it with his mouth, but when they really ask him what he said, he has no idea.
Brother, do you think this rack is okay?"
It took a long time for Du Bin to finally fix the rack.
"That's great, brother. Please make two more. It's just right for the three of us to each take one."
Du Chen clearly made use of his brother's ready-made labor.
"Okay, I'm pretty good at this now!"
Du Bin said nothing and went back to work. Actually, for children, anything other than studying is considered play. Good students and bad students are the same; few truly enjoy studying.
After a long while, Du Bin finally tightened all the racks.
"Brother, what should we do next?"
"Here, clamp the bicycle chain in a vise and remove each link."
Du Chen first clamped the bicycle chain in a vise, then found a set of punches from his father's toolbox, selected a round punch of just the right size, and told Du Bin how to remove the chain links.
"Dad, do you have any thinner enameled wire?"
Comrade Lao Du didn't say anything. He went to the small room and rummaged around again, and found a large roll of enameled wire, which was used to wrap the motor rotor. At this time, when the motor broke, it was usually rewound instead of being replaced directly.
"Here, take a look and see if it works. What are you going to use it for?"
"Dad, wrap these joints of the wire rack with enameled wire. It will be strong and look good. Also, Dad, please get me some solder wire and a soldering iron so I can solder the joints of the enameled wire later."
Comrade Lao Du went to the office to get solder wire and soldering iron for Du Chen, and Du Chen motioned Liu Yi to come over.
"Liu Yi, look at how I do it. You can learn from me. Then wrap all the connectors with enameled wire. Make sure you wrap them tightly, one circle after another. That way it looks good. Do you understand?"
Du Chen taught Liu Yi step by step, and once he taught Liu Yi, he no longer had to do it.
"Du Chen, let me give it a try."
Liu Yi watched Du Chen work for a while, then decided he was almost there, so he started talking. He also thought it was fun, and he felt a sense of accomplishment doing it himself, so Liu Yi was a little impatient.
"Here, try it."
Hearing Liu Yi's initiative to ask for work, Du Chen immediately handed the work in his hand to Liu Yi. Comrade Du rolled his eyes as he watched from the side.
On the other side, Du Bin had almost dismantled the chain. Du Chen found some gasoline to wash the chain, took out the rubber band prepared in advance, and prepared to clamp the links together.
"Wait a minute, son. I have a valve core here. Do you want to use it? It's very powerful."
Comrade Lao Du said from the side.
"Dad, it's OK. The valve core is better."
After Comrade Lao Du handed over the valve core, Du Chen put the chain links together in circles to make it a whole.
Du Chen looked at Liu Yi and found that he had not finished wrapping the gun mount yet, so he put the chain link on the table and went to the repair shop by himself.
"Hey, Dad, you still have Santana here?"
Du Chen saw a Santana parked in the workshop and asked curiously. The Santana was launched in China in 1985. Although it has been on the market for more than ten years, it is rare to see it here because it is too expensive.
"Well, that's the section chief's car, and the unit only has this one."
"Why did you stop here? Is there something wrong?"
"Well, the door glass doesn't work anymore. It's electric, and no one knows how to fix it."
"What? You don't know how to repair electric glass? I've looked in the books at home. Dad, you have a reference book that has it in it!"
"Really? I don't know. I haven't noticed it."
Comrade Lao Du felt a little embarrassed. He usually had no time to read or study. It would be so nice to just go home after get off work and lie on the bed and watch TV.
"Hey, Dad, come and take it apart. Let me take a look."
Du Chen said to his father.
"Can you really fix it? It won't make things worse, will it?"
Comrade Lao Du said doubtfully.
Du Chen rolled his eyes quietly. He had repaired many Porsches, Mercedes-Benzes and BMWs before. Could he not handle a Santana now?
Comrade Lao Du went over to remove the door covering with a half-believing and half-doubting attitude, and Du Chen went over to take a look.
"Dad, do you have a multimeter?"
"Here you go." Comrade Lao Du handed over the multimeter.
Du Chen measured it twice and said directly to Comrade Lao Du: "Dad, there is something wrong with the motor. Let's take it apart and have a look. I think the carbon brush is worn out."
Comrade Lao Du dismantled the motor with doubts. After opening it, he found that the carbon brushes of the motor were worn out and the contact was poor.
Motor carbon brushes are still commonly used accessories. Generally, there are repair kits when they break, unlike later times when the motor assembly had to be replaced directly.
Comrade Lao Du found two carbon brushes of similar size, polished them slightly, and tried putting them on. It worked!
"Sure, second brother! You guessed it right!"
"Dad, what do you mean I guessed right? This is strength, okay?"
Comrade Lao Du was about to speak when Liu Yi called Du Chen.
"Du Chen, come over and take a look. I've wrapped this up. Can you see if it works?"
Du Chen walked over quickly and took a look. Liu Yi's craftsmanship was pretty good. The enameled wire was wrapped tightly, and the circles of enameled wire were tightly fitted, as if they were wrapped by a machine.
"Nice wrapping, Liu Yi, your skills are quite good!"
