Introduction
In China, because there are more and more new energy vehicles , and motor repair is complicated, and many auto repairers have changed to do motor repair. But in , Pakistan still retains the traditional Chinese manual maintenance skills in the past, like ours, the master takes the apprentice and teaches step by step!
No matter how old you are, as long as you are here to apply for an apprentice, you must study hard and respect the master!
Today I visited a truck repair shop in Karachi, Pakistan and saw that several workers were already busy. They were about to start assembling the engine of a truck. Now we see that the cylinder block has been cleaned up by them and put it in a cleaner place to start assembly.
They all use manual
. A master led several Zhonggong to assemble an engine. (Zhonggong is an apprentice who has been apprenticing for a while and can assemble the machine manually) The master of this store is named Aka. Master Aka is now very skillful in installing the crankshaft cover back. You can see that this is a new bearing cover. Generally, we will replace the cover when we overhaul the engine. After the
tile cover was installed, a middle-aged worker poured it on the tile cover with a bottle of lubricating oil and applied it evenly with his fingers. After applying the tile cover evenly, you can install the crankshaft back. Before installing the crankshaft, Master Aka and Zhonggong wiped the crankshaft cleanly and checked whether there were any other impurities on the crankshaft. The crankshaft was at least 30 kilograms. It took two people to lift it at the same time to move it, and then the crankshaft can be carried on the cylinder block and installed.
crankshaft is placed on the cylinder body. His master tried to rotate the crankshaft first, and after confirming that there was no problem, he then used the crankshaft belt to start installing. Before installing, you should also apply some engine oil . After installation, knock it tight with a hammer and the installed crankshaft cover is manually tightened by another. These middle-aged workers are all apprentices of Master Aka. Each apprentice has learned skills from Master Aka for more than two years, and there are many places that can be completed independently by themselves.
saw an apprentice with white hair, who was 60 years old,
I saw the white haired apprentice with a bolt twisting behind him, who was nearly 60 years old, and was still following Ata. The master learned to maintain it and learned it until he was old. This spirit is worth learning. After his master tightened the cover, he then tried to turn the crankshaft to confirm that there was no problem. Master Aka took the torque wrench from Zhonggong to strengthen the crankshaft cover.
Because your screw requires a certain amount of force, if you are not well controlled, it will cause uneven force. Generally, in our country, this kind of screw is more dependent on the torque wrench. Some masters can rely on the feeling. After tightening all the screws, try to rotate and remove wrinkles. Make sure there is no problem. The rear drive shaft is installed.
Next, Master Aka brought another overhaul bag. With the overhaul bag, it was much more convenient. It contained various pads, oil seals, etc., and there were no overhaul bags before. They put newspapers on the engine and knocked them out one by one. In order to prevent oil leakage from the engine, after the master got the gasket, he applied a layer of sealant on the front end of the engine, then put the gasket to the position where the sealant was applied, then gently compact it, and then applied a layer of sealant on the gasket.
purely manual installation, the master teaches
Master Aka can put the money after applying sealant. The end cover has been installed back, and their skillful techniques have already tacitly cooperated in their years of work. At this time, Master Atta was responsible for tightening the screws of the front end cover, and several middle-aged workers were also busy installing other accessories next to the engine. After the front cover screw is tightened, you can install the timing gear back. The
machine turned out to be made in China, and I feel inexplicably proud!
After Master Aka got the formal gear, he first applied some lubricating oil to the formal gear. Then install the formal gear back. During installation, his master used his hand to tweak the crankshaft to rotate the crankshaft to a fixed position, and then install the gear back point to point.If you install formal gears, if you can't match, the engine cannot start or be powerless. It is better to have a diesel engine timing for this kind of diesel engine. Soon after Master Aka completed the installation of the gears, I walked closer and saw that there were very obvious words on the gears, which turned out to be made in China!
The machine was installed soon, and the machine was tested, and it started at once, and it was another perfect repair. Pakistani masters couldn't help but laugh happily!
Ba Tie Master praised it when it comes to making in China, making it powerful and durable!
ending
Now with the promotion of the Belt and Road Initiative and the construction of the China-Pakistan economy, more and more Chinese companies invest and build sites in Pakistan, and more and more Chinese equipment will also come to Pakistan. For Pakistani repair masters, there will be more equipment that needs repair. Pakistani masters said that in this way they will have more work and earn more money to support their families. I sincerely thank Chinese friends, China is Pakistan's eternal brother!
May China-Pakistan friendship be "higher than the mountains, deeper than the sea, sweeter than honey"
