As soon as Wan Feng returned to his grandmother's house, he lay down on the kang and fell asleep. He slept until after eight o'clock the next morning.
He overslept. This was the first time he had to wake up at this time since he came to his grandma's house.
My uncle had disappeared long ago, probably going to work.
Wan Feng got up and went outside to drink half a bucket of water.
"Breakfast is in the pot, but you won't wake up no matter how I call you." Grandma complained outside the house.
"No, let's eat together at noon. Isn't grandpa going to work at the brick factory today? I have to go see him."
One is that grandpa goes to work, and the other is that he has to repair a tractor today.
Wan Feng rode his broken bicycle out and arrived at the brick factory a few minutes later.
As soon as I entered the brick factory, I saw my grandfather Zhu Xianyu and Zhang Hai walking around the brick piles in the factory, seemingly counting the number of red bricks in the factory.
As a custodian, you naturally have to know everything about the brick factory.
Seeing that his grandfather looked like a new official who was eager to take office, Wan Feng thought it would be wise to stay away. If he got close to him, he might be forced to work as a laborer. Therefore, he did not move forward at all, but walked to the front of the tractor.
Xiao Jun knew that Wan Feng was going to repair the tractor today, so he didn't drive the tractor out. He was leaning lazily against the trailer and looking at the sky.
Wan Feng carried with him a set of patched and ragged clothes. These were clothes that his uncle didn't want anymore, so he found them and used them as work clothes.
This suit was a little too big for him, like the robes worn by masters during the Republic of China period. Wan Feng had to tie a straw rope around his waist to make it fit.
The tractor came with some simple tools, and Wan Feng used these tools to start repairing the tractor.
The first thing to remove is the ball head at the front end of the steering wheel connecting rod. Both ball heads are severely worn, which increases the steering clearance of the steering wheel and makes the toe-in unstable.
Has this tractor been used very hard? Why is this part so badly worn?
After removing the connecting rod, we started to clean up the engine.
Xiao Jun had already opened the engine cover.
"If you want to be a good driver in the future, you have to remember everything I'm doing now, including the steps and process. Now find a basin or something to drain the oil from the engine oil pan. Just unscrew this screw and the oil will flow out."
This is the advantage of having an apprentice, you don’t have to do some things yourself.
The 22 tractor uses a 2100 two-cylinder in-line engine. Most of the tractor engines in the 1980s were 2100, 4100, 2125, 4125, and the 4115 used on the Tieniu 55 tractor. The newest one is probably the 495 engine used on the Shanghai 50 produced by the Shanghai Tractor Factory. The single-cylinder one is 195. Anyway, these are the same things over and over again.
Wan Feng had dismantled countless of these engines in his previous life when he was a tractor driver. Even though this was his first time dismantling these engines, he was not unfamiliar with them and was very familiar with them.
Remove the valve cover, remove the cylinder head, remove the oil pan and connecting rod screws, pull out the piston and connecting rod, and explain to Xiao Jun while disassembling.
When everything that needs to be disassembled is disassembled, reach out and touch the grooves on the cylinder liner wall, and pull off the cylinder liner.
As for the valve device, he didn't check it. That device is not a wearing part and generally does not need to be replaced.
"See? A good cylinder liner doesn't have any grooves at all. If you touch it with your hands, you'll feel it rubbing against your fingers. That means it's severely worn."
Xiao Jun reached out and touched the cylinder liner wall and nodded.
"And the pistons and piston rings. The piston rings are almost worn out. Soon the exhaust pipe will need oil spraying. At that point, even a bottle of oil won't be enough for a day."
Wan Feng checked the crankshaft and bearing again. Without a caliper, he could only feel them by hand.
After thinking about it, I removed the fuel nozzle and diesel pump. Since they were dismantled, I took them down and repaired them together. The fuel pump and fuel nozzle were also taken for calibrating.
Wan Feng wrote down what he wanted to buy: two sets of cylinder liners, two pistons, a set of piston rings, a cylinder gasket, two steering ball joint assemblies and a calibration pump.
Two cylinder liners cost about ten yuan, two pistons are estimated to be around thirty yuan, piston rings from Shijiazhuang are about six or seven yuan, cylinder gaskets are three or four yuan, and the ball head assembly is about twenty yuan.
One hundred yuan should be about right.
When everything was dismantled, it was already ten o'clock in the morning. He waved and called Zhang Hai over.
Zhang Hai came over to listen to Wan Feng’s introduction of the losses.
"I roughly calculated the cost of these parts and estimated it to be around 80 yuan. This is just a rough estimate. I'm not sure the exact price."
Zhang Hai wrote a note asking Wan Feng to go to the accountant to get the money.
If you want to buy these parts, you can only go to the agricultural machinery company. Even if the commune tractor station has the parts, it may not be able to provide you with them.
If I want to go to the agricultural machinery company, I can only take the bus there in the afternoon. I hope the agricultural machinery company will have a day off on August 15th. If it is closed for two more days, it may be a waste of time to go there in the afternoon.
Wan Feng took off his tattered clothes, washed his hands, and went to the Wahou team headquarters to find the accountant to get money. When passing by Luan Feng's house, Luan Feng stuck her head out of the window and looked at him with a smile.
Wan Feng pointed at the team headquarters and went straight to the team headquarters without going in.
After getting the money, I went home to have lunch and then waited for the tractor by the roadside.
At about one o'clock, two tractors came rumbling over. Xiao Jun and Wan Feng were going to buy spare parts and also sat on the tractors.
Wan Feng got on the tractor and arrived at the county town an hour later. Fortunately, the agricultural machinery company only had one day off on August 15th, so they were open as usual today.
2100 and 4100 are the most widely used engines in Beiliao Province, and Hongya County Diesel Airport produces these two types of diesel engines, so there is no problem of missing parts at all.
In just over ten minutes, Wan Feng bought all the accessories.
The price was not much different from what he expected, and he actually spent more than 80 yuan on these accessories.
Xiao Jun sat on the steps in front of the agricultural machinery company waiting for the tractor to come back, while Wan Feng took the oil pump and nozzle and ran to the diesel engine factory to calibrate the pump.
At that time, only the county diesel engine factory in Hongya had the business of external pump calibration.
The labor cost for calibrating the pump was six dollars, and replacing the oil nozzle cost five dollars, so there were still a few dollars left out of the hundred dollars given by the team.
But when Wan Feng returned to the agricultural machinery company with the calibrated oil pump, the tractor delivering bricks was already waiting there.
If he had enough time, he would have wanted to ask Xia Qiulong about the sales of electronic watches, but he obviously didn't have time now.
After returning to the brick factory and loading the tractor as quickly as possible, it was already dark.
Xiao Jun had already gone home early, so Wan Feng had to call Zhang Hai over, and the two of them started the engine.
This time the engine sound is much softer and there is no more black smoke coming out of the exhaust pipe. After a little running-in, it will be a good tractor.
