Maintenance steps
1, first remove the wheel, remember to screw it well, and it will be troublesome to drop it.
2, take down the bearing, some of the wheel core is very tight, the bearing is very difficult to remove, with the six corners of the hand (that is the one that dismantling the screw) to it hard to dig it down, rest assured that the bearing is not easy to bad!
3, first use the toothbrush to wipe the dirt off the surface of the forest. You can't do this step.
4, some bearing's side cover is detachable, others are not. First, judge whether you are Perlin or not. How do you judge? Don't be in a hurry! If there is a C ring on the edge of the bearing side cover, it can be detachable. No, it is not removable, but there are exceptions.
5, if it is detachable, it's very simple. With a precision screwdriver, pry up the C ring in the gap of the C ring, then remove the side cover. Just remove the side. C rings and side covers must be closed. Once you finish washing, you may want to pack them back!
6, if it is not detachable, it is more troublesome! Use a destructive method. Use the precision screwdriver to extend into the seam of the side cover, and force the side cover to pry up. Don't doubt, that's all, but the side cover will not go back. Well, throw it off! Remember, just remove one side, and destroy both sides.
7, remove all the side covers of the bearings and start washing. Pour the oil into the bowl, then throw the bearings down and stir them up.
