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: 1. oil tank damage motor vehicle in use, found oil leakage, can clean the oil leak, soap or bubble gum in the oil leak, temporary blockage, repair with epoxy resin adhesive, the effect is better. 2. when the ruptured tubing is broken, the rupture can be cleaned, coated with soap, wound with cloth strips or rubber cloth, and tied with wire, then a layer of soap. 3. when the tubing is broken, a rubber or plastic pipe sleeve can be found to fit the diameter of the tubing. If the sleeves are not tight enough, the ends should be tightly tied with iron wire to prevent oil leakage. 4. cylinder head appears sand hole and oil leakage, leakage can be according to the size of the sand eye, select the corresponding specifications of the electrical fuse, with a hand hammer gently smash it into the sand eye, can eliminate oil leaking, leakage. 5. when the oil pipe joint leaks oil, when the motor vehicle is used, such as the leakage of the oil pipe joint of the engine, it is caused by the fact that the oil pipe horn mouth 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. 6., when the rupture of the hose is small, a layer of soap coated with a layer of soap is used to bind the leakage. If the rupture is large, the hose can be cut off, a bamboo tube or iron pipe is set in the middle, and the wire is tied up with wire. 7. fan belt breakage can break the broken belt with iron wire or open and stop the car. 8. screw hole slide screw hole slide will cause oil leakage or connecting rod loosening, making 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. 9. diaphragm or oil pump diaphragm broken or broken can be removed from the oil pump to remove the diaphragm, using glue wood board, electrical insulation wood or plastic cloth according to the original shape, size saw file molding, and wear. When the 10. valve spring is broken, the valve spring is broken, the broken spring can be removed, and the broken two segment can be installed in turn, and then it 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. .
