Replace fuel tank cap motor

10 Unwittingly, my long Yi car has traveled 110000 kilometers. It has been four and a half years since I bought a car, and the distance I have walked in a year has reached more than 25000 kilometers, with an average of more than 60 kilometers per day. Take a picture to commemorate the 110000 kilometers, but also to commemorate the passage of time.
Long Yi car as a Volkswagen magic car, there is no big problem, but there is still a little bit of temper. This does not tell a true story that happened to me. If there are similarities in the plot, it is a pure coincidence! I remember that one day, according to the usual habit of running out of gas, I drove to refuel when an accident happened. When I was refueling, I suddenly found that the fuel tank lid could not be opened. Under normal circumstances, after the door is unlocked, press the fuel tank cover and it can pop open by itself, but on this day it cannot be opened by pressing left and right. What are you going to do? see if there’s a button in the car.
Look, I only see a button on the door of the main cab. I usually use this much more, and I am familiar with it to open the trunk.
If you look again, you can only see one lever, but it’s a pity that you can only open the front hood. Usually in the maintenance of the engine can be checked for abnormal circumstances, the use of this lever, in addition, there is no button. Do you feel particularly disappointed? why do you only have the buttons of the front and rear engine cover and the trunk, but not the buttons of the fuel tank cover next to it? this question should be carefully considered!
There was no way. I was in a hurry to refuel at that time, so I made a wild effort to pry the lid of the fuel tank, but I miraculously opened it. Pay special attention to the fact that there is a round hole in the back of the tank cap. Be thankful that it is not damaged. You should not ignore this round hole. It is an important part of locking the tank cap.
After opening the lid of the fuel tank, I found that a metal rod was born in it. What is this? let’s sell it for a while, and listen to it.
So I began to think about how to take out this metal rod. If you don’t take out the metal rod, you can’t close the fuel tank cap. You can’t finish filling up, open the fuel tank and run all over the world. In the end, I found the way. Look at the picture below. This is the picture without metal rod after being removed.
So I tried to find it in this position, not on the outside, but on the inside.
Open the trunk, open the flannelette cushion, unexpectedly, the secret mechanism is in it. It is this white shell that makes me happy and makes me worry. I am glad that I finally found you, and what I am worried about is why there is no button switch, otherwise, don’t go to a lot of trouble.
Loosen these two screws and you can remove the motor of the fuel tank cap.
When I pulled the metal rod by hand, I didn’t expect that the rod would contract freely when I pulled it by hand. What is the principle? we have to study it carefully.
So after filling the oil, take the fuel tank motor for separation, a good study of the internal structure and principle.
This is the working scene of the motor after unlocking. We can see that there is a certain distance between the metal pull rod and the ring cover, and the ring cover here simulates the round hole on the inside of the fuel tank cover. At this point, the fuel tank cap can be opened.

When we press and hold the lock button, the motor will protrude a white plastic lever, push the front metal lever forward, enter the ring cover, and close the fuel tank cover. This is also the reason why there are metal bars inside after the hard pry in the picture above.
Let’s understand its internal structure again. We need to know the root of the problem before we can find the truth. With a knife in the middle to a gap, turn to a knife, you can open the shell of the motor.
After taking it apart, you can see the internal structure.
This is the fuel tank motor, often the fault is here, as for what principle, it is necessary to review the high school study of electromagnetism, magnetism to electricity.
This is the plug, which is connected to the circuit of the car, and this can be removed. sometimes the fault may be caused by loose joints.
This is the pull rod, through the rotation of the motor to drive its telescopic function.
Now try to restore the internal structure. The position of the motor is very early, and the shell reserves a large space, that is, the position of the discharge motor. When putting the pull rod, I can never find the original position, but I know that the rotating shaft is connected, otherwise how can I bring it to the pull rod?
Finally found the location, it is really a radish a hole, according to the reserved position can be assembled.
Take a side view and look at it more carefully. The motor is a small rotating shaft of metal, and the pull rod is a large rotating shaft of plastic. Is it a little bit like four or two to pull out a thousand jin?
Take another top view so that we can know the location of several internal parts.
Simulate the working state of the internal motor again. This is the state in which the motor does not work, which is the internal structure after we press and hold the unlock key.
This is the internal structure of the motor when it works normally. After pressing the lock button, the connecting current motor begins to work. At this time, the motor drives the white rod through the rotating shaft, and the white rod rotates spirally to push the metal rod forward.
At the beginning of the fault, it was judged that there was a problem with the internal coil of the motor, so a similar oil tank cover motor was bought on a certain network, and the price was not expensive, more than 30 yuan on the Internet.
There is still a certain gap between the online purchase and the physical object, and the original one is better. Just install it in this order. All right, this is the end of the principle of the fuel tank cap motor. Next time you encounter friends with similar experience, do not use brute force to pry the fuel tank cap. In case the round hole in the tank cap is broken, it will be an irreversible secondary injury. The best way is to directly remove the fuel tank cap motor, which can solve the problem that the fuel tank cap can not be opened. All right, that’s all for this program. See you guys next time.
