There will be some trouble in driving out. If there is a breakdown or failure in the running and there is no need for spare parts supply at the same time, we have to take some urgent repair methods. Some simple and easy methods of emergency repair are introduced as follows: when the motor vehicle is used, it is found that the oil tank is leaking, can clean the oil leak place, apply soap or bubble sugar to the oil leak place, temporarily block the oil, and use the epoxy resin adhesive to repair it, the effect is better. When the tubing is broken, the ruptured place can be cleaned, coated with soap, wound with cloth strips or rubber cloth, and tied with wire, then a layer of soap. When the tubing is broken, a rubber or plastic pipe sleeve suitable for the diameter of the tubing can be found. If the sleeves are not tight enough, the ends should be tightly tied with iron wire to prevent oil leakage. According to the size of the sand eye, the electrical use fuse of the corresponding specifications is selected, and the hammer can be lightly smashed into the sand eye with the hand hammer, and the leakage and water leakage can be eliminated. When the motor vehicle is used, such as the oil leakage of the engine oil pipe joint, it is caused by the fact that the oil pipe horn and the oil pipe nut are not sealed. The cotton yarn can be wrapped around the horn of the horn, then the tubing nut is tightened with the tubing joint, and the bubble gum or maltose can be chewed into a paste, and it is applied to the nut seat of the tubing. When the rupture is not large, a cloth coated with a layer of soap will be used to bind the leakage. If the rupture is large, the rupture of the hose can be cut off, a bamboo tube or iron pipe is placed in the middle, and the wire is tied tightly. The broken belt can be tied up with wire or the car should be opened and stopped. The screw hole slider will cause oil leakage or loosening of connecting rod to make it unable to work. At this time, the original screw can be hammers and flatten with the hammer, so that the two sides will expand and tighten again, but it can not be repeatedly removed. Can be removed from the oil pump to remove the diaphragm, with glue wood board, electrical insulation plywood or plastic cloth according to the original shape, size saw file molding, and wear. After the valve spring is broken, the broken spring can be removed, and the two broken segments can be installed in turn, and then they can be used. Also, find a piece of iron 1 millimeter thick, cut into a round piece of 1 millimeter larger than the diameter of the spring, and cut a round hole in the inside, the diameter is less than 4 millimeters of the diameter of the spring, and the outer edge is cut into 4 millimeters by 6 millimeters every 6 millimeters. After being cut, each one folds one piece to form a double side spring seat slot, and then the spring head is loaded into the iron groove. .
