Rebirth of the Auto Giant

Chapter 16 Finding the Trouble

"Do you know what the problem is, Master Wang?" Officer Huang saw Wang Shi's operation just now, measuring current and voltage, and knew that Wang Shi was really capable.

Just now Wang Shi tried to connect the iron directly by bypassing the key switch through the starter. The starter made a clicking sound but the engine did not move. It must be that the engine is stuck and the crankshaft is locked and cannot move.

"Now it seems that the engine is broken. We need to disassemble it and take a look." Wang Shi said.

The engine used in the fourth-generation Crown produced in 1971 was a 4-cylinder in-line electronic injection engine with a displacement of 2.4 liters.

Wang Shi's previous repairs were all carburetor engines, and this is the most advanced engine Wang Shi has ever seen.

Drain the engine oil first, and check that there are many silver-white metal particles in the drained engine oil. Seeing this, Wang Shi knew that the engine must have locked up. This was obviously caused by the wear of the cylinder liner and piston rings.

This is a big project, and the sun is so hot, so I asked the other party to bring over a sun umbrella and tools and get ready to start work.

Also, remove the engine cover for easier maintenance, and remove the fuel nozzle and spark plug.

I opened the rocker cover and found that the engine oil inside was black and had a lot of carbon deposits. I looked at the engine's factory date and found that it was produced in 1971. The car was eight years old and had a lot of carbon deposits.

It was the first time I saw someone repairing such a high-end car. It was a novelty. Soon there were spectators standing around. They were basically children from the compound. There were older ones like Wang Xi and others, and there were also naughty children with runny noses.

, everyone watched Wang Shi, who was similar to themselves in age, dismantling the engine, with envy in their eyes. At this moment, Wang Shi became like a hero in their eyes.

Soon several drivers inside also arrived and watched Wang Shi dismantle the engine.

This is a top-mounted rocker arm. Take off the cover and remove the two rocker arm shafts. Remove the cylinder head and see the piston and cylinder liner inside.

The results are clear at a glance.

The cylinder liner and piston inside have been locked together.

"Did you see it? The piston ring and cylinder liner inside are locked together. Go and call your responsible person." Wang Shi said, looking at Officer Huang who was standing behind him and watching his work attentively.

"Wait a moment." The other party said and rushed out. Soon the middle-aged man named Zheng came over. When he saw the engine parts dismantled into a pile, his eyes towards Wang Shi became gentler.

"Uncle Zheng, now we know the fault. It's the engine cylinder."

"Pull the cylinder?" The other party didn't know what "pulling the cylinder" meant, so Wang Shi said it too professionally.

"Oh, the engine is broken, and the piston and cylinder liner inside are stuck together, so the car can't move."

The other party finally understood what Wang Shi said, "Comrade Wang, can you fix it?"

"Uncle Zheng, you can, but you will have to take care of the broken parts after you dismantle them later," Wang Shi said in a very formal tone.

You have to say this, these things are not repaired, they need to be replaced with brand new parts. If it doesn't work, put it back on yourself now, otherwise if you wait and dismantle it all and say it doesn't work, it will be in vain.

How did interpersonal relationships come about? It was handed over little by little. Where is this place? This is the General Logistics Complex. If you establish a good relationship with this place, you might be able to use it some time.

"Okay, you can dismantle it first and see what parts are needed. We'll take care of it. You'll have to worry about the rest of the work," the other party said.

"Okay." Wang Shi heard the other party's words and sent him away. Then he asked Officer Huang to find two jacks and jack up the two front wheels of the car, use solid wood blocks to stabilize them, and then remove the oil pan.

, then remove the piston from under the oil pan by pushing against the connecting rod, and then remove the cylinder head.

…

After working for a long time, I finally took out all the broken ones by lunch time.

The four cylinder liners, pistons, piston rings, and connecting rod bushes were neatly placed on the floor.

All four pistons were broken and could not be used and needed to be replaced. There were also piston rings and connecting rod bushes. After checking the valves, there were also some problems. However, Wang Shi considered the current difficulties in the country and spent foreign currency to buy these parts, so he finally decided to use

The valve can be polished with sand and can be used again.

If these and the valve seats can be replaced directly with new ones in modern times, now that the country is in difficulty, these imported parts need to be purchased with foreign currency, so save what you can.

I checked the oil pump and it was fine. I checked the water pump carefully and found that there was no problem, but there was a problem with the belt. This was the culprit of this failure. The belt was old and cracked. Insufficient tension led to insufficient water pump speed, which caused the engine water temperature to be too high.

Pull the cylinder.

After doing this, the next step is to write a list of required parts.

A set of overhaul kits, four pistons, piston rings, connecting rod bushes, and valve seals must also be replaced. If some of them are damaged, if they are not replaced, the oil will enter the combustion chamber from the valve seals and accumulate in the combustion chamber for a long time.

Increased carbon causes engine weakness.

The carbon deposits on the piston are caused by the valve oil seal.

After checking the list and finding no problems, I attached the engine model at the end so that the salesperson could know the engine model and what types of parts to sell. Give the list to Director Huang and you'll be fine.

After working for a long time, the time came to around three o'clock in the afternoon.

The things have been handed over to the other party for purchase. All I have to do is wait for the parts to arrive before repairing. But before that, I have to write some tools for the other party to find, such as a torque wrench and valve grinding sand.

The torque wrench is used when assembling some special screws, such as cylinder head screws, connecting rod nuts, camshaft fixing screws, etc. These have specified torques. More or less will not work, and the order is specified.

When assembling these screws, a torque wrench is required, which is still available today, but the current torque wrench is a pointer type and can be used. After the 21st century, high-precision adjustable torque wrenches are used.

The leadership office of the General Logistics Complex Building.

Zheng Wu was looking at a pile of documents at his desk when suddenly the door opened and a middle-aged man in his fifties walked in.

"Old Wang, what's the matter?" Zheng Wu was the uncle Zheng who just went downstairs to talk to Wang Shi, and the man who walked in was named Wang Tucheng. He was Wang Xi's father and the director of a department in the main backyard.

"Old Zheng, I found an opportunity to improve the skills of our comrades in the transportation class. Do you want to hear it?" Wang Tucheng sat across from him, looking at a pack of Daqianmen cigarettes on the table, and took one and lit it.

.

"Come on, I don't have time to grind my teeth with you." The black pen in Zheng Wu's hand was writing something on the white paper, and he kept saying.

"I found that the boy named Wang who we hired downstairs has some skills. Didn't you notice? He dismantled the RB car as soon as he asked, and he was so skillful. The parts were arranged so neatly that you can see

He turned out to be a veteran, and now I really believe that he will definitely repair our car Crown. I think so, with such a good opportunity, why not let him teach some knowledge about car repair to the soldiers in our transportation class?

, it’s considered training, what do you think?” Wang Tucheng took a deep breath after speaking and looked at his comrades who were writing.
