Rebirth of the Auto Giant

Chapter 107 20% Profit

Wang Shi had a late-night snack with six new employees and rode home a little drunk. Fortunately, the traffic police did not check for drunk driving at this time, otherwise he would have to go in.

When I got home, I turned off the engine and parked the car, washed my feet and got ready to go to bed.

"Why are you so drunk? You smell like alcohol. Go and don't sleep with us tonight." Zhao Min saw Wang Shi sitting on the edge of the bed and sniffed. There was a strong smell of alcohol coming from Wang Shi.

With a disgusted face, he pushed Wang Shi with his jade legs.

Wang Shi originally wanted to kiss his sleeping daughter, but when he heard what his wife said, Wang Shi sniffed it and said, "How could it be? I didn't drink much, it was all beer." He found that the smell was not as strong as the other party said.

"Hurry up and go down. You can go to the west wing to sleep today. There is an empty bed there. The smell of alcohol is so strong. If the baby smells the alcohol, it will affect the brain development. Come on, don't sleep with us." After Zhao Min finished speaking, he used

The jade leg held the king stone.

"Okay, okay, I'll go, I'll go." When Wang Shi heard this, it seemed to make sense. He had seen such reports on the Internet before, saying that the father who was drinking dipped some wine into his chopsticks and gave it to his child to lick.

Caused irreversible brain damage in children.

"Daddy is going to sleep outside tonight, baby." Wang Shi looked at Mingyue's pink face and looked so cute.

Wang Shi had just left the house when Zhao Min suddenly remembered something and said: "Oh, by the way, Lin Zhengtang came over just now and didn't see you. He said that the accessories have arrived and asked you to take the time to go to the store. The customers are anxiously waiting."

"I know, I'll make some time tomorrow." Last time, a valve spring of a crown car in a certain agency broke, and the valve fell into the cylinder, damaging the piston and cylinder liner. The cylinder head was not too big, so it was still usable.

When I came to the store, I picked up the imported parts from Germany through the general logistics department, but I didn’t expect them to arrive today.

The next day, Wang Shi got up early, had breakfast outside, and came to the store.

Lin Zhengtang was already there, laying out the accessories and waiting for Wang Shi to come.

An overhaul kit, a cylinder liner, a set of cylinder liner seals, a set of piston and piston rings, one intake and exhaust valve and one exhaust valve seat ring, six valve seals, and a pair of intake and exhaust valve springs

, and two pairs of valve lock clips.

"Master, the engine has been cleaned." Lin Zhengtang saw Lin Zhengtang walking over and said to Wang Shi.

"Well, the preparations are well done. I'm going to change clothes." After Wang Shi finished speaking, he went to the back room to change clothes and asked Lin Zhengtang to install the cylinder liner sealing ring on the cylinder liner and apply butter to prevent the sealing ring from being cut during installation.

.

When Wang Shi came back after changing his clothes, he saw Lin Zhengtang installing a sealing ring on the outside of the cylinder liner and applying a layer of butter.

"When pressing the cylinder liner onto the cylinder body, the force of both hands must be even and balanced. Don't use too much force at once. Find a capable wooden board." Wang Shi explained some key techniques for installing the cylinder liner.

Lin Zhengtang had personally seen Wang Shi repair engines several times and had seen him install cylinder liners.

Now that Wang Shi is quite busy in the factory, he intends to let his apprentices run the repair shop. So now, as long as Lin Zhengtang wants to learn, Wang Shi will try his best to teach him.

Lin Zhengtang quickly found Ganjiang's plank.

"Come here, I'll watch." After Wang Shi finished speaking, he watched the other person come to the front of the car with the cylinder liner.

"Use even force and press down slowly. Don't rush, take your time." Wang Shi patiently instructed from the left side.

"Yes." Lin Zhengtang felt the master's kindness, nodded, and slowly put the cylinder liner into the body, then placed the wooden board on the cylinder liner and pressed it down evenly with both hands. The sealing ring of the cylinder liner was coated with butter.

Because of the pressure, it slid in with a firm pressure.

Lin Zhengtang felt the force and slowly applied force downwards along the cylinder liner. Finally, the cylinder liner was completely pressed down, making it flush with the machine body.

"How do you feel?" Wang Shi asked.

"Um,"

"Remember this feeling and steps, and follow this technique when installing cylinder liners in the future. Everything is accumulated little by little. Rome was not built in a day." Wang Shi said.

"Thank you, Master, I will remember it." This time Wang Shi taught him according to his wishes. Lin Zhengtang also felt that this time the master treated him differently than before, and he was also moved in his heart.

"As for me, I will spend more time in the factory in the future, and I will come to the store less and less. From now on, I will leave it to you to run this place. You have to grow up quickly. As long as you are willing to learn, I will take care of you."

Everything will be taught to you, and if you don't understand anything in the future, just ask." Lin Zhengtang would rather not go to the factory but prove in the shop that he wants to become an auto mechanic.

Wang Shi simply taught him everything and let him run the store from now on.

Next, Wang Shi guided on the side, and Lin Zhengtang took action, refrigerated the piston pin for a while, installed the piston pin and the connecting rod together, and installed locking clips on both ends.

"The dimensions of the piston pin, piston and connecting rod are very high when they are processed. After using ice for a while, the effect of thermal expansion and contraction is used, and it is very easy to assemble without damage. Of course,

, if conditions permit in the future, it will be more convenient to use freezing spray." Wang Shi said.

"Master, are you going to install the piston rings next?" Lin Zhengtang asked.

"That's right."

There are two masters and apprentices, one teaches seriously and the other studies attentively.

"When installing this piston ring, please pay attention. The two gas rings on top are divided into upper and lower parts during assembly. The side with the mark is facing up, which is the mark." Wang Shi basically didn't do anything, and guided Lin Zhengtang to do it.

The piston ring is installed on the piston, and an adjustment cut is made in the direction of the piston pin.

According to the order, install the piston into the cylinder liner, and tighten the two connecting rod bolts according to the specified torque with the specified torque wrench.

"That's it, install the other five pistons." Wang Shi said.

"Thank you, master."

After installing the piston, install the second cylinder's valve seat ring, intake and exhaust valves, and valve springs to the cylinder head, then the cylinder head gasket and cylinder head.

This is an overhead camshaft engine. Wang Shi taught his disciples how to align the ignition timing when installing the camshaft, and installed the camshaft...

The two masters worked hard for more than an hour and nearly two hours before they finally installed the engine. Most of the time, Wang Shi was there to teach. After the instruction, the apprentice understood it and then installed the next one, so the progress was relatively slow.

"Okay, add oil." Since this was Lin Zhengtang's first time doing it, Wang Shi had to stand aside and watch, otherwise he would sometimes forget a screw in the cylinder and cry to death over the loss.

Because imported parts from Germany are not cheap.

This engine oil is not specifically for Mercedes-Benz. It is Mobil 0w--40 engine oil imported from the United States when I helped Claire from Coca-Cola Company repair her car last time. The viscosity index is 40, which is enough for running in the northern region in winter.

After adding more than one bottle of engine oil, it was finally full and the remaining half will be handed over to the customer later.

"Beep!" Wang Shi went to the cab and turned the key. A low beep sounded and the car shook slightly.

"Okay, let him idle for a while and then turn off the engine. Notify the customer to stop. The parts will be increased by 20% according to the base given by Uncle Zheng and the others. The labor fee will be 500. This is what was agreed last time."

"I'm leaving."

"Okay, master, I'll close the shop and let the customers come to the next car."

"Okay, I'll go then. When you're done, close the door and go back early to accompany your grandpa. Just hang a sign and leave your address at the door. I guess there won't be any business today."

"Okay." Lin Zhengtang replied.

After Wang Shi left, Lin Zhengtang made a list of the money for repairing the car, closed the door, and rode his bicycle to notify the customer to pick up the car.

Starting today, Wang Shi will conduct a series of professional training on maintenance for Haoruduo and the other six people.
