Removal and installation of the fuel pump from the gauge of a stock of fuel The fuel pump with the gauge of a stock of fuel. The petrol engine of all-wheel drive model The fuel pump is together with the gauge of a stock of fuel in a fuel tank. All-wheel drive models owing to necessity of placing карданного a shaft have a fuel tank, two-piece. In this case in each chamber the gauge of a stock of fuel is located. In the right chamber there is an electric fuel pump. On an illustration the fuel pump of the petrol engine of all-wheel drive cars is above shown. The description concerns also cars with the diesel engine of 1.9 l, and also to diesel engines of 2.5 l about 5/02 releases. The gauge of a stock of fuel consists of a float and a potentiometer. At decrease in level of fuel the gauge float falls also. The potentiometer connected with a float, raises thus electric resistance of the gauge. Pressure on panels of devices and the index of a stock of fuel thus goes down "empty" moves in a direction. At cars with a fuel tank, two-piece, the control panel processor calculates the general stock of fuel on the basis of signals of two gauges then gives out a signal on the index of a stock of fuel.
At removal of the fuel pump a fuel quantity can flow out. Fuel steams are poisonous and inflammable. Therefore watch good ventilation of a workplace. Use the gloves proof in relation to influence of fuel. Do not apply open fire, danger of a fire! Keep in readiness the fire extinguisher. Before removal of the fuel pump and the gauge empty an as much as possible fuel tank. The tank should be filled no more, than on 2/3. The radial fan which electric motor is outside of an air stream can be applied To workplace ventilation and has productivity not less than 15 m 3 / hour. Models with a forward drive Removal
Installation
Models with a full drive and front-wheel with the 6-cylinder diesel engine of release to 4/02 For отворачивания запорного rings the key 3087 is necessary. The tightening moment 145Нм.
In the right chamber the fuel pump with the gauge of a stock 1 is established. In the left tank the gauge of a stock 2 is established. The all-wheel drive car, and also the front-wheel car with the 6-cylinder diesel engine of release to 4/02: the Fuel pump is fixed баянетным by a shutter. For its removal it is necessary to turn to the left on a corner 15 ° the special tool. At installation it is necessary to turn accordingly to the right. On баянетном a shutter there are two notches and an arrow specifying in a direction "is closed". |
