PETROL ENGINE
In each compartment of a fuel tank there is a sensor of indication of level of fuel.
Removal
| PERFORMANCE ORDER |
| 1. Merge fuel from a tank. If only one sensor is dismantled, it is necessary to merge fuel only from this compartment. |
| 2. Remove drain топливопровод (74) with a standard clip (011). |
3. Remove drain топливопровод on a basic plate of the fuel level sensor (B4/1). For this purpose weaken and shift back a shlangovy clip.
Prevention
The flowed-out fuel collect rags or merge in suitable capacity. Connecting input of the pipeline close a suitable stopper, or insert into a hose a pure bolt with suitable diameter of a carving.
|
4. Unscrew a round nut (89/1). In a repair truck the special tsapfovy key is for this purpose applied. If you have no such key, insert into shlitsa of a safety ring a suitable plastic wedge and weaken a ring in easy blows of a hammer.
Prevention
Do not apply some metal because of danger of emergence of a spark.
|
| 5. Take the fuel level sensor. |
| 6. Remove pipelines (88/3) and (88/4) from the jet soaking-up pump on the fuel level sensor. |
|
Installation
| PERFORMANCE ORDER |
| 1. Get pipelines (88/3) and (88/4) on the fuel level sensor. |
| 2. Establish the fuel level sensor, having equipped it with new profilirovanny consolidation so that thorns of the sensor entered into gearing in grooves (88/2) fuel tanks. |
| 3. Twirl a tsapfovy key a round nut with the moment of 55 N of m. |
| 4. Get a drain hose and fix it a shlangovy collar, remove a shlangovy clip. |
| 5. Fill in fuel and at the working engine check tightness of all points of connection. |
|
DIESEL ENGINE
In each compartment of a fuel tank there is one fuel level sensor.
Removal
| PERFORMANCE ORDER |
| 1. Merge fuel from a tank. If the sensor only acts in film, it is necessary to release its clips only. |
| 2. Disconnect a standard clip (011) drain fuel lines (70). |
3. Remove the drain line from a locking plate of the fuel level sensor. For this purpose weaken and shift back shlangovy clips.
Prevention
Collect rags the following remains of fuel or catch them in a suitable vessel. A flange of the pipeline close a stopper, for example, a pure bolt with suitable diameter of a carving which insert into the pipeline.
|
4. Turn off a nut (89). In a repair truck the special tsapfovy wrench is for this purpose applied. If there is no such key, put in a groove of a safety ring a suitable plastic wedge and weaken a ring in easy blows of a hammer.
Prevention
Do not use metal: danger of an iskreniye!
|
| 5. Take the fuel level sensor. |
| 6. Remove pipelines (90) from the ezhektorny pump on the fuel level sensor. |
|
Installation
| PERFORMANCE ORDER |
| 1. Get the pipeline (90) on the fuel level sensor. |
| 2. The fuel level sensor with a new profile sealing ring (89/1) establish so that pins of the sensor entered into gearing in grooves of a fuel tank. |
| 3. Screw an eye nut a tsapfovy wrench with the moment of 55 N of m. |
| 4. Put on a drain fuel hose and fix it a clip for a hose. Remove from a hose the plug. |
| 5. Fill in fuel and check tightness of all junctions at the working engine. |
