Adjustment

PERFORMANCE ORDER

Adjustment of the maximum number of turns 1. To check up, whether the pedal of an accelerator and the elements transferring its moving freely move. 2. To start the engine and to warm up it to normal working temperature. 3. To finish the engine to the maximum number of turns. The prevention It is impossible to exceed as much as possible admissible number of turns of the engine; the engine on the maximum number of turns should be no more than 5 seconds. 4. If the maximum number of turns differs from recommended (see subsection 3.2.1.2.1) it is necessary to adjust by means of an adjusting bolt 1 (see fig. Adjustment of the fuel pump). 5. To check up time of reduction of number of turns from maximum before idling (no more than 5 seconds). If this time is more, it is necessary to execute adjustment of idling and the residual expense preventing deenergizing of the engine. Adjustment of idling and the residual expense 6. To establish a plate in the thickness of 4 mm between a bolt (3) adjustments of the residual expense (the engine preventing deenergizing) and the lever (2) accelerators (a fuel dosage) (fig. Adjustment of the fuel pump see). 7. To establish a plate in the thickness of 20 mm between the lever (5) (fig. Adjustment of the fuel pump see) idling and a restrictive bolt. 8. To establish position of a restrictive bolt of adjustment of the residual expense so that number of turns of the engine made 900±100 rpm. 9. To take a plate in the thickness of 20 mm. The idling lever should return to contact to an adjustment bolt. 10. To take a plate in the thickness of 4 mm. To establish position of a bolt of adjustment of idling so that number of turns of the engine made 870±20 rpm. To check up behaviour of the engine at sharp release accelerator pedals. If time of reduction of number of turns too big, or too small and the engine stops, it is necessary to repeat adjustment. If the engine all the same stops, it is necessary to tighten on 1/4 turns a bolt of adjustment of the residual expense in case of too slow reduction of number of turns of the engine or to unscrew on 1/4 turns in case of too fast reduction of number of turns of the engine. The prevention It is not necessary to tighten or unscrew this bolt more than on 1/4 turns.

Removal

PERFORMANCE ORDER

1. To disconnect from the accumulator a weight wire. 2. To unhook spring hooks of fastening of the top casing of a drive of system timing. 3. To establish the car on the stationary lift. 4. To unscrew a bolt of fastening of the bottom casing of a gear belt, then to weaken the second bolt and to turn round the weakened bolt a casing downwards. 5. To lower the car and to remove the top casing of a drive of system timing. 6. To designate position of a cable of a pedal of an accelerator on the lever of the fuel pump and to unhook from it a cable. To unscrew a bolt of fastening of the lever and to take a cable. 7. To disconnect a socket of an electric wire from the proof-reader of an advancing of injection of the cold engine. 8. To disconnect from the pump sockets of pipelines of injection and sockets of pipelines of return and the proof-reader of a dose of fuel (apertures to close corresponding stoppers or caps). 9. To unscrew fastening bolts скобы the bottom arm of the fuel pump. To unscrew fastening bolts скобы to the block of cylinders of the engine. 10. To disconnect a socket of electric wires of the electromagnetic valve of deenergizing of the engine (valve STOP). 11. Cautiously to disconnect the vacuum pipeline between the valve of correction of pressure турбокомпрессора and an inlet collector. 12. To remove приводной a generator belt. 13. To take from the block of cylinders of the engine заглушку a control aperture for installation of the piston of 1 cylinder in ВМТ. 14. To disconnect pipelines: fuel, returnable and pressure corrections турбокомпрессора. 15. By means of a corresponding key to turn a pulley of a cranked shaft clockwise so that to establish the fuel pump in a position of "12 hours", and cam-shaft cut in a position of "8 hours". 16. To turn a cranked shaft of the engine counter-clockwise so that to establish the fuel pump in a position of "11 hours". 17. To screw up against the stop the mandrel (1) for installation of the piston of 1 cylinder in ВМТ (fig. send for installation of a cranked shaft in position ВМТ see the Sizes). 18. To weaken a bolt (2) fastenings of a roller of the tension device of a gear belt of a drive of the fuel pump, to weaken a gear belt and to tighten a bolt of fastening of a roller of the tension device. To unscrew three bolts (1) fastenings of a pulley of the fuel pump. 19. To remove a gear belt and a pulley of the fuel pump. 20. To remove the fuel pump from the block of cylinders of the engine.

Installation

The prevention

At installation of the new fuel pump it is necessary to take stoppers (заглушки), closing apertures of fuel pipelines and to pour in the pump diesel fuel for simplification of removal from it air.

PERFORMANCE ORDER

1. To check up, whether is in a control aperture sideways the block of cylinders of the engine оправка for installation of the piston of 1st cylinder in ВМТ. 2. By means of the corresponding adaptation to establish an aperture in a pulley of a drive of the fuel pump opposite to an aperture in its case. 3. By means of bolts Torx to attach a forward part of the case of the fuel pump to the block of cylinders of the engine. 4. After extraction of the adjusting adaptation to establish a pulley on a flange of a drive of the fuel pump and slightly to screw up bolts of fastening of a pulley. 5. To arrange the adaptation for installation of the fuel pump in a pulley and to be convinced that it has entered into an aperture of a flange of a drive of the fuel pump. 6.
