 PERFORMANCE ORDER

1. If check is made at established on engine TNVD, instead of in the course of installation of the last, disconnect a negative wire from the battery and cover with polyethylene the generator. Remove форсуночные tubes (Removal and installation ТНВД, subsection "Removal", item 12 see).
2. If yet have not done it, ослабьте tightening the screw and-or a nut and shift lengthways drive a cable of turns of fast idling its trailer clamp, completely having taken away it from the executive lever on the pump (the lever of fast idling should nestle on an emphasis) (Removal, installation and adjustment of the thermosensitive gauge of turns of fast idling see).
3. Achieve combination of adjusting drillings of blocking of a cranked shaft (Fixing cranked/distributive shaft and ТНВД for the purpose of prevention of casual hit of valves in contact to pistons in the course of performance of procedures of service of the car see). Remove blocking tool and turn a shaft back (counter-clockwise) approximately on a turn quarter.
4. Turn out the screw of access located between штуцерными connections four форсуночных of tubes in back part ТНВД. Having turned out the screw, get under the pump suitable drain capacity for gathering of spilt fuel. Wipe begin to flow pure rags.
5. Screw in a back part of the pump a special carving nozzle (Citroёn № 4123) and fix in it циферблатный a measuring instrument (the measuring instrument and a probe for check of installation of the moments of injection on ТНВД systems Bosch see an illustration of Tsiferblatnyj).

The nozzle can be got in any good firm shop of automobile accessories. Arrange a measuring instrument so that it плунжер it has appeared in the middle of the course, then strongly tighten a nozzle counternut.

6. Slowly повращайте a cranked shaft forward-back for the purpose of moment definition when piston TNVD will appear in the bottom point of the course (НМТ). Having achieved demanded position of the piston, null a measuring instrument.
7. Slowly turn a cranked shaft in a normal direction until again there will be no possibility of introduction of a blocking core.
8. The indication fixed by a measuring instrument should correspond to requirements of Specifications. Otherwise ослабьте forward and back nuts of fastening of the pump also start to develop slowly its case until the device will not register demanded value. Having achieved satisfactory result, strongly tighten pump fixture.
9. Turn a cranked shaft on one turn with three quarters in a normal direction, achieve transfer of the piston of the pump in position НМТ (item 6 see) and null a measuring instrument.
10. Slowly turn a cranked shaft before combination of blocking drillings (having resulted the engine in position ВМТ) and repeat check of installation of phases timing.
11. In case of need again ослабьте fixture of the pump also repeat the procedures described in subitem 8-10.
12. Having achieved satisfactory result, turn out a carving nozzle and remove a measuring instrument.
13. Screw into place the access screw (do not forget about a sealing washer) and strongly tighten it.
14. If check was made during pump installation, operate, as Removal and installation ТНВД is described in section.
15. If the pump is established on the engine, return to the place of a tube of atomizers and tighten накидные their nuts штуцерных connections with demanded effort. Connect a negative wire to the battery and remove air from the power supply system (Filling of the power supply system with fuel and removal from it air stoppers see). Start the engine and make adjustment of turns of idling and turns of prevention spontaneous останова (address to the Head Routine maintenance). Adjust also приводной a cable of turns of fast idling (Removal, installation and adjustment of the thermosensitive gauge of turns of fast idling see).
