Vehicle gasoline pump failure emergency repair
1. Internal and external rocker arm clearance is too large (1), the outer and outer rocker pad gasket pad can be used metal, copper, iron, semi-circular opening pin made of "factory" glyph. During installation, make sure there is a certain gap between the inner and outer rocker arms and wrap the gasket to prevent falling. (2) Check whether the thickness of the gasket is reached by hand reaching the petrol pump mounting hole on the cylinder, slowly turn the crankshaft of the engine manually and touch the tip of the driving eccentric of the petrol pump on the cam in the direction of not pumping oil When installed, install the petrol pump (the gasket between the petrol pump and the cylinder is installed beforehand). Install the gasoline pump fastening bolts and screw in a little, by hand to promote the gasoline pump to fit with the cylinder, and then relax, at this time if the suction effect, the gasket is too thick, should be adjusted. 2. Rocker arm breakage When the rocker arm break, can take one of the following methods: (1) with a wire or thin string tethered to the hand pump arm, the other end of the lead to the cab, with hand movement control , The car can only drive at low speed. (2) If there is a small pulley, the above-mentioned wire or string can be tied to the accelerator pedal through a small pulley and controlled by the foot. (3) The broken rocker removed, find a choke or throttle pull soft pull tube, so that the hole fully lubricated, the one end is fixed on the hand pump handle, while the other end Fixed in the wiper lever on the appropriate position (Note: pull tube should be fixed in the body of the appropriate position). Use, open the wiper switch, the use of wiper lever swing back and forth so that the pump constantly pumping oil. (4) For electric wiper models, the electric wiper assembly can be removed, fixed to the gasoline pump at the top of the appropriate position, with the ends of the wire were fixed on the handle and wiper lever in the appropriate position . Take a good wiper power supply, you can use the electric wiper lever swing back and forth to bring hand crank pump oil. The above several methods of choice, according to the specific conditions at the time decision. 3. The pump membrane rupture (1) For the pump membrane is not serious damage, for example, only the edge of damage, can be damaged at the depth of soap, the damaged pump film and a good pump membrane separated from each other, and each piece Damaged at staggered open and then loaded. (2) If the pump membrane cracks longer, available plastic, tarpaulin, film cut into the original shape of the film, sandwiched between the original film. (3) If gasoline is found to flow into the crankcase from the rupture of the pump membrane, the crankcase oil is severely diluted. Should be replaced with new oil. If there is no new oil, the old oil in the crankcase can also be released for heating, so that the old oil can be temporarily used after the gasoline in the oil is evaporated. 4. Inlet and outlet valve seal is poor (1) If the bakelite oil valve is not flat, the valve can be turned over to continue to use, or the uneven side of the oil surface grinding, it is best to use abrasive paste on the glass Flatten. Good grinding of the valve can be installed before use. (2) If the inlet and outlet valves are poorly sealed due to gumming, the jelly may be washed off with alcohol or high-concentration white spirit or acetone. (3) If the oil valve has ruptured, replace it with a thinner piece of glass. The method of making is to immerse the glass in water and clamp the glass piece slowly into the shape of the oil valve with pliers. 5. Cracked cup (1) If the cup is cracked, it can be repaired with old plastic (such as a toothbrush handle). First, the oil cup rupture thoroughly clean, the plastic on the exhaust pipe heating (be careful not to plastic stained with oil), to be melted quickly press the crack in the cup, and let it adhere to a certain Thickness, with the exhaust pipe on the heater in advance will repair the Department by pressing the flat, so that the bond more firmly. (2) If the oil cup is broken, replace it with a substitute. Many types of substitutes, such as bottles, small thermos cover, beverage boxes, bamboo, small cups, flashlight caps, cream bottles and so on. If the substitutes are not high enough to be fixed, a padding pad 2 may be placed on the bottom of the substitutes. The thickness of the spacer should be fixed firmly by using the screws as a substitute. If you choose the bottle as a substitute, the processing methods are as follows: with a cotton-stained cotton thread wrapped around the bottle to be cut off, and then ignite the cotton thread, when the cotton is almost ready to be burned, quickly into the cold water. As the bottle collapses rapidly due to the cold, the bottle is disconnected at the winding. If the broken oil cup with a partition structure in the middle, the soft board can be processed into the shape and size of the original partition, and according to the installation position of the original partition can be placed. 6. The outer arm and cam wear too much If the outer arm and the cam worn even make the fuel pump is too small, you can thin the gas pump and the liner between the cylinder and even removed (but can not leak from here Oil). 7. Pump spring break If the pump spring break, the steering wheel can be used at the top of the electric horn button spring alternative or other similar springs instead. 8. Gasket leakage (1) If the liner can not afford to seal due to stiffness, this liner can be soaked in hot water, softened and then coated with grease to continue to re-use. (2) If the above method still can not be used or the liner has ruptured, it can be processed according to the original liner size, such as yellow board paper or asbestos board. 9. Gas pump produces "gas resistance" Gas pump "gas resistance" to eliminate as follows: (1) the engine is stopped, open the hood for ventilation; (2) cold water to the tubing to help wash out the cool , Exhaust pipe and petrol pump oil cup watering); (3) soaked in cotton yarn or rags with cold water on the pump on the cooling, to be a period of time after the carburetor into the tubing removed by hand (4) If the temperature is too high, the air resistance frequently occurs when the sandbags can be made, soaked in water on the pump above to cut off the exhaust pipe to the gasoline pump Radiant heat. In order to improve the insulation effect of sandbags, we should often use cold water soaked. 10. Damaged Fuel Pumps If the damage to the fuel pump does not work properly, replace the fuel pump with the following method: fill the fuel tank with a container and install it at a position higher than the carburetor, Connected to form a self-flowing oil supply. Pay attention to fire prevention when using this method.
