GENERAL INFORMATION

Measurement of movement of the piston by means of measurement by the indicator of hour type of raising of the final valve leaning on a piston bottom

Air filter

1 – the filter case with the broad camera,

2 – the filtering element,

3 – filter cover,

4 – air supply pipeline

Installation of the indicator with the holder on the fuel DPC pump (in cars since 1987)

1 – indicator of hour type,

2 – holder of the indicator,

3 – bolt of fixing of the indicator,

4 – bolt of fixing of the holder


ENGINES OF THE CARS RELEASED TILL 1987

Removal

PERFORMANCE ORDER
1. To disconnect and remove the accumulator.
2. To remove the air filter.
3. To disconnect from the fuel pump elements of management, and also returnable fuel-supply lines from the pump and from nozzles.
4. To remove pipelines of supply of fuel to nozzles and to muffle their openings, to disconnect the pipeline of supply of fuel to the fuel pump.
5. To uncover a head of the block of cylinders.
6. By means of a stripper for springs of valves together with auxiliary elements (No. 21.024, 21.024/04 and 21.024/03) to squeeze springs of the final valve of the 4th cylinder, to take a core of a pusher and to turn the valve lever on 90 °.
7. To remove a sheet casing from below of the engine.
8. To install the piston of the 4th cylinder in VMT (both valves in the 1st cylinder are partially open), to remove crackers, a basic plate and springs of the valve from the final valve of the 4th cylinder and to lower the final valve on a piston bottom.
9. To install the indicator of hour type on the second to a bolt of a cover of a head of the block of cylinders and to operet its measuring tip on a head of a core of the final valve of the 4th cylinder.
10. To check installation of the piston of the 4th cylinder in VMT and to nullify the indicator.
11. To carefully turn a bent shaft aside, opposite to the direction of its working rotation so that the final valve leaning on a bottom of the piston of the 4th cylinder moved down to 7 mm.
12. To turn a bent shaft in the direction of its working rotation (elimination of gaps) on 4,15 mm so that the indicator of hour type showed value of 2,85±0,05 mm (before piston VMT).
13. To unscrew two bolts with an internal hexagonal nest of fastening of the fuel pump to a forward cover of the engine and to take the fuel pump.

Installation of the fuel pump and installation of the beginning of injection

PERFORMANCE ORDER
1. Sideways the fuel pump to unscrew a bolt of fastening and to unscrew the stopper closing a control opening for installation of the moment of injection.
2. To turn a pump shaft so that the adjusting sign (flute) of a rotor of the pump was directed up (was in the middle of a control opening.
3. To install the fuel pump and to fix it by two bolts with an internal hexagonal nest.
4. To check installation of a rotor of the pump. To fix the holder together with the indicator sideways of the pump and to operet a measuring tip of the indicator on an adjusting sign of a rotor of the fuel pump.
5. To turn a bent shaft aside, opposite to the direction of its working rotation so that the piston of the 4th cylinder appeared at distance of 7 mm before VMT. To turn a bent shaft clockwise so far the indicator on the fuel pump will not show the maximum value with an accuracy of 0,1-0,2 mm.
6. This value has to make 2,85±0,05 mm before VMT of the piston of the 4th cylinder. If it not so, then it is necessary to weaken bolts of fastening of the pump and carefully to turn it.
7. To repeat the actions described above, beginning from installation of the piston of the 4th cylinder at distance 7 mm before VMT, before obtaining necessary value on the indicator of hour type.
8. To tighten pipelines of high pressure, since the back pipeline.
9. To install the piston of the 4th cylinder in VMT and to remove the devices used for installation of a corner of an advancing of injection.
10. To establish springs of the final valve of the 4th cylinder, a basic plate and crackers.
11. To turn a bent shaft aside opposite to the direction of its working rotation until opening of the final valve of the 1st cylinder.
12. To insert a core of a pusher of the final valve of the 4th cylinder, to install the lever of this valve and to fix the closing stopper on the fuel pump.
13. To check gaps of valves and to screw a cover of a head of the block of cylinders.
14. To attach elements of control of the fuel pump and pipelines. To install the air filter. To establish a sheet casing of the engine.
15. To establish and connect the accumulator. To remove air from fuel system.

ENGINES OF THE CARS RELEASED AFTER 1987

Installation of the indicator with the holder on the fuel DPC pump (in cars since 1987)

1 – indicator of hour type,

2 – holder of the indicator,

3 – bolt of fixing of the indicator,

4 – bolt of fixing of the holder.


Removal

It is carried out in the same way, as well as it is described above.

Installation of the moment of injection of fuel

PERFORMANCE ORDER
1. On each pump there is a stopper from artificial material on which the adjusting size in millimeters is beaten out. This size different for each pump; it is measured by the indicator of hour type with the extender Ford 23-0.
2. To remove the closing stopper (1) located on a pump cover. (2 – a tip, 3 – passatizh).
3. To fix on the pump the indicator of hour type together with the extender Ford 23-0 (fig. 1 B.19).
4. To install the indicator so that his shooter began to move (the measuring tip slightly concerns a pump rotor).
5. To establish an arrow of the indicator of the pump on zero.
6. To install the piston of the 4th cylinder at distance of 2,85±0,4 mm before VMT.
7. The indicator of hour type of the pump has to show at once the value which is beaten out on a pump stopper.
8. If this condition is not satisfied, then it is necessary to weaken bolts of fastening of the fuel pump and very carefully to turn it in one or other party before obtaining the necessary indication of the indicator on the pump.
