1、 Remove the wheel
Our first step is to remove the wheel. This operation seems very simple, just loosen the screws on the wheel hub, but the sequence of removing the screws is exquisite. The wheel hub of Golf 6 (detailed picture quotation) is a five-screw structure. The diagonal sequence should be adopted during disassembly, which is equivalent to the step of drawing a five-pointed star. In this way, theoretically, the force on each screw will be more uniform, which can minimize the deformation of screws and mounting holes.
With the help of the air cannon, the maintenance technician quickly unloaded Xiaogao's four wheels and put them aside. These wheels have only been in service for 10 months, and there is no wear and tear except for some dirt, but they can not escape the fate of being replaced - perhaps this is the fate of the original parts of golf (detailed picture quotation).
2、 Set tyre
Go back to the point. The maintenance technician took the new wheel hub out of the packing box, carefully placed it on the tire changer and fixed it, and then the tire can be put on.
The operation of "cover" seems simple, but when you look at the structure of the tire and touch the material of the tire, you will find that it is quite laborious to cover the tire on the wheel hub. Looking at the thin body of the maintenance master, we also sweat for him. The maintenance technician first brushed Vaseline on the inner edge of the tire, and then put the tire on the wheel hub, while stepping on the pedal to make the base rotate, slowly put the tire on the wheel hub with the help of the fork on the tire changer, and press the tire edge into the wheel hub with force.
In the process of tyre fitting, the maintenance technician said to us while operating: "brute force is useless. The more violent the tyre is, the more uncooperative the tyre is. We must not rush." That said, it is useless to do this work with less strength. Let's look at the master again. He is sweating. Although the maintenance technician pressed the tire very carefully, the tire was still a bit "naughty": I thought it had been set for a while, and then it bounced out after turning the base, so I could only press it again.
3、 Inflation check
After painstakingly putting the tire on the wheel hub, the maintenance technician should also inflate the tire according to the standard air pressure, and check the tightness of the tire and the wheel hub while inflating. As the air pressure rises, the inner edge of the tire is constantly squeezed and gradually fits with the wheel hub. There is a loud "bang bang" sound of rubber bouncing off the wheel hub from time to time, but it sounds like a tire burst, which really startles us
After working for more than an hour, the maintenance technician repeated the above laborious operations four times, and finally put four tires on the new wheel hub. Although the maintenance technician has been soaked, he can't rest because there are still key steps to be completed
