Du Jianshan returned to the machine repair shop, put the parts he had picked up on the table, wiped the sweat from his forehead, reached out and unscrewed the screwdriver, and deftly began to disassemble the cylinder block.
He moved quickly and steadily, and in no time, he removed the broken piston ring from the engine.
Liu Dafu was leaning against the door, smoking, looking completely unconcerned.
But seeing Du Jianshan's swift and fierce actions, he suddenly became suspicious, stubbed out his cigarette, and moved a little closer.
"Comrade, have you repaired engines before?"
Du Jianshan didn't even look up, his hands never stopping: "I learned a little from my dad before, I've disassembled all the common cars and machines in our factory."
"Which factory does your dad work at?" Liu Dafu asked with a hint of curiosity in his eyes.
"From Ansteel, in the chain steel workshop, a veteran technician," Du Jianshan replied casually.
Liu Dafu was startled and couldn't help but take a step closer, staring at Du Jianshan's hand.
With one hand holding the cylinder steady, Du Jianshan used a wrench to quickly turn the screws, disassembled it, and carefully took out the old piston rings and piston cap, setting them aside.
He turned around, picked up the parts Aygul had found, compared them, and then took out his tools to start polishing and repairing them.
This job is meticulous; the slightest carelessness could damage the parts. This time, Liu Dafu really paid close attention.
Seeing Liu Dafu staring intently, Ayiguli leaned closer and whispered with a smile, "Comrade, do you believe me now? My Brother Du is really something."
Liu Dafu chuckled, his expression turning serious: "I believe you, I believe you can tell, you're definitely a true expert."
Du Jianshan worked diligently for almost half an hour, during which he used a wire brush to polish the parts, the tools making a crisp and powerful clanging sound.
He worked quickly and efficiently, polishing the parts before applying lubricant and carefully assembling them.
Liu Dafu watched with growing alarm and couldn't help but say, "Comrade, this job is not easy. Your skills are better than those of the experienced workers in our station."
Du Jianshan smiled and said, "Children from poor families mature early. Before going to the countryside, they had done all sorts of jobs, so they developed their skills."
Liu Dafu nodded, feeling a surge of admiration.
About ten minutes later, Du Jianshan tightened the last screw with a wrench, straightened up and took a breath: "It's done. Let's see if it can start."
Liu Dafu looked astonished: "Really healed?"
Du Jianshan wiped the engine oil from his hands: "Why don't you try and see?"
As he spoke, he reached out and pulled the starter lever. The engine immediately emitted a deep roar, and after a few turns, it actually started running smoothly!
Boom boom boom—
The clear roar of motors suddenly filled the machine repair room.
Liu Dafu's eyes widened in astonishment, his mouth agape: "This...this is really fixed? Comrade, you're amazing!"
Aygul clapped her hands with joy, her eyes filled with admiration: "Brother Jianshan, how come you can do everything!"
Du Jianshan wiped the oil off his hands and said with a smile, "It's nothing, I just learned a little bit, it was just a coincidence."
Liu Dafu quickly took out a pack of cigarettes, lit one, and handed it over: "Comrade, I'm impressed! Your skills are amazing! Our agricultural machinery station has been looking for you for days and you couldn't fix it, but you solved it in one go today!"
Du Jianshan waved his hand: "I don't smoke, thank you."
Liu Dafu wasn't embarrassed at all, and praised him repeatedly: "You're really capable! But, comrade, there's something else I'd like to ask you to take a look at."
"What's the matter?" Du Jianshan asked.
Liu Dafu pointed to another tractor parked outside and said with a bitter face:
"That tractor's tire has been flat for two months, and we haven't been able to fix it because we're short of parts, which is delaying our farm work. If you have any ideas, the farm machinery station will waive all the diesel fuel we need for this plowing trip!"
Du Jianshan nodded: "Let's go, take me to see."
The three went outside, where the tractor was parked quietly in the yard, its tires flat.
Du Jianshan squatted down to examine the tire carefully and found that the puncture was quite large, with a large crack in the tire sidewall.
Liu Dafu sighed, "The tire is so badly damaged that it can't be repaired, and we don't have any new tires to replace it. We can make do with other parts, but what are we going to do with this tire?"
Du Jianshan stared at the damaged area for a moment, then suddenly slapped his thigh: "This is simple, use fire to patch the tire!"
