Due to the “Yellow to Green†policy introduced by Shandong Province, the car was upgraded to the National 3 model. For so many years, Master Liu has a good cherish for this old man.

Selling a cow test drive, from then on the truck
In the early years, Master Liu was still a vigorous young man. Because of the reform and change of the year, a cow was assigned to the family. Fortunately, the cow was pregnant and gave birth to two cows. In that era, the cow was very valuable. Because there is no land to grow in the family, and there is no need for cattle to cultivate the land, so one of the cows sold 800 yuan to test the driver's license.
Master Liu’s old Dongfeng Tianlong
From then on, Master Liu became attached to the truck. He said: "At that time, learning the car was not as simple as it is now. At that time, it took the master to take a long time. Now some of my driving habits were taught by the master at that time. There is security awareness, this is too important."

Once Master Liu was also a member of the Taian Transportation Group, Master Liu said: "Don't take care of anyone in the delivery, even if the security guards in the factory area may be the old drivers who retired that year." It can be seen that Master Liu There is a special feeling for the driver's career and the transportation group. Now, when I return here again, I am a little excited.
Trailer admission, initial inspection to be dismantled
The three major pieces of this old Tianlong are Dongfeng Cummins L series 375 horsepower engine, Datong 12-speed gearbox and 4.11 speed ratio rear axle. The tires are 295/80R22.5 size tires.

Although this old Tianlong can still drive, but due to regulations and emission restrictions, this car can not get on the road, so it is dragged into the inspection plant by the trailer. From the appearance, after 13 years of wind and rain, this old Tianlong has already shown traces of the years.
For this old Tianlong, Master Liu is particularly willing to invest. In order to ensure the quality of oil, he usually only adds oil from PetroChina and Sinopec.

Open the front cover, Master Liu said to us enthusiastically: "You don't look old here. I haven't changed parts for so many years. Most of these are original parts. You can see the production code on this part. See you.
Lao Tianlong stopped at the trench and prepared for engine disassembly.
After a simple inspection, Lao Tianlong stopped at the trench to prepare for engine disassembly, and Master Liu performed the final process check.
Overall, the results of this demolition inspection are very satisfactory to both Master Liu and Dongfeng Cummins technicians. You can see that there are good aspects, and you can also see problems in the user's use. The structure of the vehicle is similar to the Domino brand, and it is not the existence of an independent structure. If there is a problem in one link, it will cause problems in the whole vehicle.
Master Liu is definitely a good hand for the maintenance of vehicles, but it has exposed many problems and not very good habits in use.
Master Liu re-ignited and listened to the engine sound.
After re-installing the parts and cleaning, Master Liu re-ignited and listened to the voice and said: "Listen to how good the sound is, and it will be fine to run in this state." For the quality of Dongfeng Cummins and the car itself, Master Liu is excited. Said: "The quality of Dongkang is one of the best in many engines I have seen. It is the same as the new one in the 2 million kilometers. I chose the right one!"
Master Liu has already booked a new generation of Tianlong flagship, still matching the Dongfeng Cummins engine. Master Liu has extra trust in Dongfeng Cummins. He also said that driving in the future will correct those wrong driving habits. After all, the national six cars and the national two cars still have A big gap.
Thirteen years of wind and rain, the veteran retired has returned. Master Liu looked at his old buddy and said quietly: "Old man, you have been working hard for so many years, this time you have a good rest."
