5.4.14. Distributive fuel pipeline

GENERAL INFORMATION

Prevention

It is forbidden to try to dismantle the entrance union as its connection with the distributive pipeline is executed by the one-piece. It can lead to damage of details.

At dismantle from the engine of the distributive fuel pipeline assembled it is necessary to show care not to damage electric sockets and raspylitelny tips of nozzles.

It is necessary to protect openings of pipelines and knots of fuel system from dust and dirt hit. At carrying out servicing and repair it is necessary to muffle openings jams and to close unions caps.

To clear

Before demontazhy it is recommended to clear outside the distributive fuel pipeline by means of a cleaner for the engine in aerosol packing. It is forbidden to immerse the distributive fuel pipeline in liquid solvent.

Prevention

Before a detachment of unions it is necessary to dump pressure of fuel in system and the distributive pipeline.

To remove or disconnect

PERFORMANCE ORDER

1. Negative wire of the storage battery.

2. A hose of ventilation of a case of the engine from a camshaft cover.

3. Electric sockets of fuel nozzles (4шт.).

Prevention

At dismantle of pipelines it is necessary to use the second wrench for deduction of unions from rotation. Otherwise damage of the distributive pipeline or sealing rings is possible.

4. The feeding fuel pipeline.

5. The drain pipeline from a regulator of pressure of fuel.

6. Vacuum bars from a pressure regulator.

7. Clips (2 pieces) distributive pipeline.

8. Distributive fuel pipeline.

To disassemble

Prevention

If the nozzle was removed from the distributive pipeline and left in the inlet pipeline, it is necessary to replace both sealing rings and a nozzle collar.

PERFORMANCE ORDER

1. To remove and throw out a sealing ring from a raspylitelny tip of a nozzle. If the nozzle was removed from the distributive pipeline, it is necessary to dismantle both sealing rings.

2. Collars of nozzles if necessary.

3. Holders of consolidations and consolidation of shtutserny connections of feeding and drain fuel pipelines. For демонжа holders of consolidations to use a small screw-driver. To throw out holders and consolidations.

To collect

PERFORMANCE ORDER

1. To grease with engine oil new sealing rings and to establish them on nozzles.

2. Collars of nozzles if necessary.

3. New holders of consolidations and consolidation of shtutserny connections of feeding and drain fuel pipelines.

4. To press holders with consolidations.

5. New consolidations (2 pieces) shtutserny connection of the drain fuel pipeline.

To establish or attach

PERFORMANCE ORDER

1. If nozzles were dismantled, to insert them on the places into nests of the distributive pipeline.

2. To establish on nozzles collars. The collar should settle down parallel to the electric socket.

3. To insert nozzles assembled into nests of the distributive pipeline so that collars and electric sockets were outside. To establish a nozzle coaxially with a nest, to enter a collar into gearing with ledges of a nest and then completely to move a nozzle into a nest against the stop.

4. If fuel pipelines were dismantled, to attach them to the distributive pipeline and a pressure regulator. To tighten unions of feeding and drain fuel pipelines. For deduction from rotation of the case of a regulator of pressure it is necessary to use the second wrench for which are provided лыски on the case. To tighten a nut of the entrance union. For deduction from rotation of the entrance union it is necessary to use the second wrench.

5. The distributive pipeline on a head of cylinders of the engine.

6. Bolts (2 pieces) fastenings distributor pipeline foot. To tighten bolts of fastening of the distributive pipeline.

7. Electric sockets of nozzles. To develop nozzles so that wires were not tense.

8. A hose of ventilation of a case of the engine to a camshaft cover.

9. A vacuum hose to a cover of a regulator of pressure of fuel.

10. Negative wire of the battery.

To examine

PERFORMANCE ORDER

To include ignition and, without starting the Engine, to check tightness of connections of fuel pipelines.
