Wan Feng returned to his grandmother's house and began to sleep as soon as he arched his head onto the kang, and slept until more than eight o'clock the next morning.

Overslept, this was the first time he had slept in these days since he arrived at his grandmother's house, and he slept until this time to get up.

My brother-in-law has long been gone, and he probably went to work.

Wan Feng got up and went to the field to drink half a scoop of water.

"Breakfast is in the pot, no matter how you wake up. Grandma complained outside the house.

"Don't eat it, let's eat together at noon, didn't grandpa go to work in the brick factory today, I have to go and see." ”

One is that my grandfather goes to work, and the other is that today he is going to repair a tractor.

Wan Feng rode out on his broken bicycle and arrived at the brickyard 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 stacks of the brick factory, and seemed to be counting the number of red bricks in the brick factory.

When a custodian naturally has to know everything about the brick and tile factory.

Seeing that his grandfather looked like a new official taking office, Wan Feng felt that it was wiser to stay away, if he made up for it, there might be a possibility of being arrested as a laborer, so he didn't go forward at all, but walked in 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 lazily leaning on the tractor and looking at the sky.

Wan Feng carried a set of torn clothes full of patches, which was a set of clothes that his uncle didn't want, and he found it to take as a job.

This set of clothes is a little too big to wear on the body, like the coats worn by those masters during the Republic of China, Wan Feng had to tie a straw rope around his waist to make do.

The tractor came with some simple tools, and Wan Feng used them to start repairing the tractor.

The first thing to disassemble is the ball head at the front end of the steering wheel linkage, both ball joints are very worn, which increases the steering clearance of the steering wheel and the toe is unstable.

Could it be that this tractor has made a lot of effort, why is it so badly worn out in such a place?

After disassembling the connecting rods, it was time to clean up the engine.

Xiao Jun had already lifted the lid of the machine.

"If you want to be a good driver in the future, you have to remember everything I do now, including the steps and processes, now you find a basin or something to put the oil out of the engine oil bottom, it is this screw that unscrews it and the oil flows out. ”

That's the advantage of having an apprentice, some things don't have to be done yourself.

22 tractors use 2100 two-cylinder inline engines, most of the tractor engines in 80 are 2100, 4100, 2125, 4125 and 4115 on the Tieniu 55 tractor.

These engines Wan Feng in the last life, but the tractor driver does not know how many times he has disassembled in the past few years, don't look at this life, he is still the first time to disassemble these engines, but he is no stranger to them at all, and he is completely familiar with them.

Remove the valve chamber cover, remove the cylinder head, remove the oil pan and connecting rod screws to pull out the piston and connecting rod, and explain to Xiao Jun while dismantling.

When the things that need to be disassembled are disassembled, reach out and touch the groove on the wall of the cylinder liner and pull out the cylinder liner as well.

As for the valve device, he didn't check it, and that set of things is not a wearing part, and it generally doesn't need to be replaced.

"See, the intact cylinder liner is not a little groove, you touch it with your hands, this cylinder liner is grinding, this is serious wear. ”

Xiao Jun reached out and touched the wall of the cylinder liner and nodded.

"And the piston and the piston rings, which are almost gone, and in a few days the exhaust pipe will be filled with oil, and at that point you won't be able to use a pot of oil for a day. ”

Wan Feng checked the crankshaft and bearing again, and without calipers, he could only touch it by hand.

After thinking about it, I removed the grease nozzle and diesel pump, and since it was dismantled, I took it down and repaired it together, and the oil pump and the fuel nozzle were also taken to correct it.

Wan Feng wrote down what he wanted to buy: two cylinder liners, two pistons, one piston ring, one cylinder gasket, two steering ball assemblies and a school pump.

Two cylinder liners cost about a dozen yuan, two pistons are estimated to cost about 30 yuan, piston rings cost about six or seven yuan to Shijiazhuang rings, three or four cylinder gaskets, plus ball head assembly is about 20 yuan.

A hundred dollars should be about the same.

When all this was disassembled, it was already ten o'clock in the morning, and Zhang Hai was beckoned over.

Zhang Hai came over to listen to Wan Feng's introduction of the loss.

"I roughly figured out these parts, and estimated that they cost more than 80 yuan, which is only the approximate price, and I don't know how much it is. ”

Zhang Hai wrote a note asking Wan Feng to go to the accountant to get the money.

If you want to buy these accessories, you can only go to the agricultural machinery company to buy them, even if the commune tractor station has accessories, it is estimated that they may not be able to match them all.

If you want to go to the agricultural machinery company, you can only take a car in the afternoon, but I hope that the agricultural machinery company will have a day off on August 15, and if you go to the afternoon for two more days, you may go in vain.

Wan Feng took off his torn clothes and washed his hands and went to the team headquarters to find an accountant to get money, and when he passed by Luan Feng's house, Luan Feng poked his head out of the window and looked at him with a smile.

Wan Feng pointed at the team headquarters and went directly to the team headquarters without going in.

After receiving the money, go home for lunch and wait for the tractor on the side of the road.

At about one o'clock, two tractors suddenly drove over, and Xiao Jun wanted to go with Wan Feng to buy accessories and sit on the tractor.

Wan Feng got on the tractor and arrived at the county seat an hour later, fortunately the agricultural machinery company only had one day off on August 15, and today they are open as usual.

The 2100 and 4100 are the most widely used engines in Beiliao Province, and Hongya County Diesel Airport produces these two diesel engines, so there is no shortage of parts at all.

In just ten minutes, Wan Feng bought all the accessories.

The price difference from his expectation was not large, and these accessories really cost more than eighty yuan.

Xiao Jun sat on the steps in front of the agricultural machinery company and waited for the tractor to come back, while Wan Feng ran to the diesel engine factory with the oil pump and the oil nozzle to check the pump.

At that time, only the county diesel engine factory in Hongya had the business of pumps for foreign schools.

The working hours of the school pump are six yuan, and it costs five yuan to change a grease nozzle, and there are a few dollars left after the hundred yuan given by the team.

But when Wan Feng returned to the front of the agricultural machinery company with the calibrated oil pump, the tractor delivering bricks was already waiting here.

If he had enough time, he would have wanted to ask Xia Qiulong about the sales of electronic watches, but now he obviously doesn't have time.

After returning to the brickyard and loading the tractor as fast as possible, it was already dark.

Xiao Jun had already gone home early, Wan Feng had no choice but to call Zhang Hai, and the two of them set the engine on fire.

This time the sound of the engine is much softer, the exhaust pipe no longer emits black smoke, as long as it is a little running-in, this is a good tractor.
