Reiz's Maca wheel hub is uneven, just reinstall it. 1, the first step is to disassemble the wheel. This operation looks very simple, just loosen the screws on the hub, but the order of removing the screws is particular. The hub is a five-screw structure, and it should be disassembled in diagonal order, which is equivalent to the step of drawing a five-pointed star. Theoretically, the stress of each screw will be more uniform, and the deformation of the screw and the installation hole can be minimized. 2. Take the new wheel hub out of the packing box, carefully put it on the tire remover and fix it, and then you can start loading tires. First, apply vaseline to the inner edge of the tire, 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 dismounting machine, and press the tire edge into the wheel hub. 3. After installing the tire on the wheel hub, you should also inflate the tire according to the standard air pressure, and check the tightness between the tire and the wheel hub while inflating. With the increase of air pressure, the inner edge of the tire is constantly squeezed and gradually fits with the wheel hub.
